Key Facts about Madagascar:
A tropical cyclone named Gamane that swept across the island of Madagascar killed at least 18 people and displaced thousands more, the country's disaster management office said recently.

About Madagascar: 

  • Located off the coast of East Africa in the Indian Ocean, Madagascar is the second-largest island country in the world.
  • It covers an area of 592,800 sq. kilometers.
  • Geography: The country can be divided into three parallel longitudinal physiographic regions.
    • The coastal strip in the east, the central plateau and the western regions of low plateaus and plains.
    • The Tsaratanana Massif region at the northern end of the island is home to Madagascar's highest point, Maromokotro, at 2,876 m. 
  • History:
    • France invaded the island in 1883. France officially declared Madagascar a French colony in 1896.
    • After World War II, in 1947, locals fought for their independence from France in what became known as the Malagasy Uprising. In 1960, Madagascar finally became an independent nation.
  • Capital: Antananarivo
  • Languages: Malagasy, French
  • Government: It is a semi-presidential republic. The public elects a president, who in turn appoints a prime minister to put together a cabinet to advise the president. 
  • Economy: Eighty percent of Madagascar’s economy is fueled by agricultural industries, including forestry and fishing. Among the island’s most frequently sold agricultural products are coffee, vanilla and sugarcane.
  • Biodiversity:
    • Lush rainforests, dry deserts, and grassy plains cover the island, with coral reefs and mangrove forests stretching along its coastlines. 
    • Almost 90 percent of the plants and animals living on Madagascar aren’t found anywhere else in the world. That’s because strong ocean currents have isolated the island from the African continent, so the species living there haven’t traveled beyond the island’s borders.

Fish otolith
Ornaments from fish otoliths have made a market debut, which are crafted by a group of enthusiastic fisherwomen in Vizhinjam, trained by scientists from Central Marine Fisheries Research Institute (CMFRI).

About Fish otolith:

  • Otoliths are biomineralised ear stones that help fish hear and provide it a sense of balance. These are important in fish studies as they have species-specific shapes and grow throughout their life.
  • They are commonly known as "earstones," are hard, calcium carbonate structures located directly behind the brain of bony fishes.
  • There are three types of otoliths, all of which aid fish in balance and hearing:
    • Sagitta: It is involved in the detection of sound and the process of hearing or converting sound waves into electrical signals.
    • Asteriscus: It is involved in the detection of sound and the process of hearing.
    • Lapillus: It is involved in the detection of gravitational force and sound.
  • Different species have otoliths of different shapes and sizes; and cartilaginous fishes, such as sharks, skates and rays, have none. 
  • Significance:
    • These otoliths can be used to identify the species, size, age, growth rate, and season of death of an individual fish.
    • Analysis of the oxygen isotope values of fish otoliths can provide information on the temperature of the water in which the fish lived.

What is a Non-Performing Asset (NPA)?
The Gross Non-performing Assets (GNPA) of the Indian banks are projected to see further improvement, potentially reaching up to 2.1 per cent by the end of the fiscal year 2025.

About Non-Performing Asset (NPA): 

  • A NPA is a loan or advance for which the principal or interest payment remained overdue for a period of 90 days. They can include various types of loans, such as personal loans, business loans, mortgages and credit card debt. 
  • When the ratio of NPAs in a bank's loan portfolio rises, its income and profitability fall, its capacity to lend falls and the possibility of loan defaults and write-offs rise.
  • Types of NPAs: Different types of NPAs depend on how long they remain in the NPA category
    • Sub-Standard Assets: An asset is classified as a sub-standard asset if it remains as an NPA for a period less than or equal to 12 months. 
    • Doubtful Assets: An asset is classified as a doubtful asset if it remains as an NPA for more than 12 months.
    • Loss Assets: An asset is considered a loss asset when it is “uncollectible” or has such little value that its continuance as a bankable asset is not suggested. However, some recovery value may be left in it as the asset has not been written off wholly or in parts.
  • NPA Provisioning:
    • Provisioning means an amount that the banks set aside from their profits or income in a particular quarter for non-performing assets, such as assets that may turn into losses in the future.
    • It is a method by which banks provide for bad assets and maintain a healthy book of accounts. It is done according to which category the asset belongs.
  • Gross non-performing assets (GNPA) and Net non-performing assets (NNPA): Banks are required to make their NPA numbers public and to the RBI from time to time. There are primarily two metrics that help us understand any bank's NPA situation.
    • GNPA: GNPA is an absolute amount. It tells you the total value of gross non-performing assets for the bank in a particular quarter or financial year, as the case may be.
    • NNPA: NNPA subtracts the provisions made by the bank from the GNPA. Therefore, net NPA gives you the exact value of non-performing assets after the bank has made specific provisions.
  • The NNPA is a measure of the actual losses that a bank has incurred on its NPAs. A high NNPA indicates that a bank has incurred large losses on its NPAs.

What are X-Class Solar Flares?
Earth was recently hit by an X-class solar flare strong enough to ionize part of the planet's atmosphere.

What are Solar Flares?

  • Solar flares are large explosions that occur at the sun's surface when twisted magnetic field lines suddenly snap, emitting large bursts of electromagnetic radiation. They are seen as bright areas on the sun and they can last from minutes to hours.
  • In a matter of just a few minutes, they heat the material to many millions of degrees and produce a burst of radiation across the electromagnetic spectrum, including from radio waves to x-rays and gamma rays.
  • Although solar flares can be visible in white light, they are often more readily noticed via their bright X-ray and ultraviolet emissions.
  • Effect of Solar Flare on Earth:
    • The intense radiation emitted during a solar flare can affect satellite communications, disrupt radio signals and even pose a risk to astronauts in space.
    • Additionally, the increased solar radiation can lead to geomagnetic storms, which may impact power grids and cause auroras (northern and southern lights).

About X-Class Solar Flares:

  • Flares are classified according to their strength. The smallest ones are B-class, followed by C, M and X, the largest.
  • Similar to the Richter scale for earthquakes, each letter represents a ten-fold increase in energy output. Within each letter class, there is a finer scale from 1 to 9. 
    • So, an X is 10 times an M and 100 times a C. 
  • C-class flares are too weak to noticeably affect Earth. M-class flares can cause brief radio blackouts at the poles and minor radiation storms that might endanger astronauts.
  • The biggest X-class flares are by far the largest explosions in our solar system. X-class flares are most common during solar maximum.

What is Butterfly Cicada?
Scientists recently uncovered a dazzling new cicada species known colloquially as “Butterfly Cicadas” from Meghalaya.

About Butterfly Cicada: 

  • It is a newly discovered species of cicada belonging to the genus Becquartina. It brings the total number of known species in the genus Becquartina to seven.
  • It was discovered in Meghalaya. It marks the first-ever record of this genus in the country.
  • The colorful wings of the cicada earned it the nickname “butterfly cicada”, with the species name “bicolour” reflecting its two distinct colour forms.
  • Features:
    • The species is localised in the Garo Hills preferring thick forests and native vegetation. The basal one-third of the hind wing is rich saffron and the apical two-thirds are matte black with prominent rich saffron squarish spots.

What are Cicadas?

  • Cicada, (family Cicadidae) is any of a group of sound-producing insects. They have two pairs of membranous wings, prominent compound eyes, and three simple eyes (ocelli).
  • Cicadas are medium to large in size, ranging from 2 to 5 cm (0.8 to 2 inches). More than 3,000 species of cicadas are known. Most of them are tropical and occur in deserts, grasslands, and forests.
  • Male cicadas produce loud noises by vibrating membranes (tymbals) near the base of the abdomen. Female cicadas usually lay their eggs in woody plant tissues that drop from the plant when, or shortly after, the eggs hatch.

What are SLAPP Suits?
A Supreme Court bench recently recorded observations on how courts should decide pre-trial injunctions against media organisations, and the growing use of SLAPP suits.

About SLAPP Suits: 

  • The term ‘SLAPP’, stands for Strategic Lawsuit Against Public Participation. The concept of a SLAPP lawsuit evolved in the US, where it was observed that certain lawsuits were filed targeting individual or group litigants who voiced their concern over important or considerable social issues in the public arena.
  • The subject matter of the suit would target an act of public participation, such as engaging in an issue of societal or political significance, in the form of journalism, advocacy, whistleblowing, peaceful protests or boycotts, activism, or simply speaking out against abuse of power.
  • As such, winning the lawsuit is not the focus. The plaintiff’s goal is typically accomplished if the defendant succumbs to fear, intimidation, mounting legal costs or simple exhaustion and abandons the criticism.
  • The remedies sought are usually substantial amounts of damages and generally aggressive or disproportionate to the subject matter of the dispute.
  • SLAPP suits are routinely filed for libel, slander, defamation, abuse of process, malicious prosecution, conspiracy, invasion of privacy, and tortious interference with contract or business relationships.
  • The most common SLAPP suits have often involved a powerful corporation suing local citizens for speaking against their company.

What is Section 120B of the Indian Penal Code (IPC)?
The Supreme Court recently dismissed the review petitions filed against its judgment related to Section 120B of the IPC.

About Section 120B of the IPC:

  • Section 120A of the IPC defines the offence of criminal conspiracy. Section 120B of the IPC, on the other hand, defines the punishment for criminal conspiracy.
  • Criminal Conspiracy under IPC is an agreement between two or more persons to commit an illegal act or to commit a lawful act by illegal means. In other words, it is a criminal offence where two or more individuals agree to plan and execute a criminal act.
  • Section 120A of the IPC states: “When two or more persons agree to do or cause to be done, an illegal act or an act which is not illegal by illegal means, such an agreement is designated a criminal conspiracy”.
  • For a conspiracy to be established, there must be an agreement between the conspirators, a common intention to commit an illegal act, and an overt act in furtherance of that intention.
  • The agreement does not have to be in writing or expressed verbally; it can be inferred from the conduct of the parties.
  • The Doctrine of Agency in a Criminal Conspiracy:
    • It is said that a criminal conspiracy is a partnership in crime because every member involved is a joint and mutual agent to each other for the common purpose, i.e., execution of the conspired crime.
    • By this doctrine of agency, the law contemplates that the act of one of the members in the conspiracy is deemed as the act by each of them, due to all members being equally liable. 
  • Punishment for Criminal Conspiracy:
    • Under the purview of IPC 120B, conspiracy is divided into two categories depending on the nature, gravity and punishment for the said offences. Also, whether the case is bailable or not, depends on the above-mentioned circumstances. 
    • In the first part, it states that if the conspiracy is to commit an offence of serious nature, an offence which is punishable with death imprisonment, imprisonment for life, or with rigorous imprisonment for at least a term of 2 years or more, or if there is no punishment mentioned in the code for the offence committed, such person shall be treated in the same manner as of the offence committed and abetted by him.
    • Whereas, in the other part of Section 120B, conspiracy other than the offence committed under the first part, conspiracy to commit an illegal act is covered.  In this kind of case, the section provides a uniform punishment, which means imprisonment of either description for a term which may extend up to six months, a fine, or both.

Food Waste Index Report 2024
According to the Food Waste Index Report 2024, households across the globe wasted over one billion meals a day in 2022.

About Food Waste Index Report 2024:

  • It a study jointly authored by the United Nations Environment Programme (UNEP) and WRAP (Waste and Resources Action Programme), a U.K.-based non-profit.
  • It tracks the global and national generation of food and inedible parts wasted at the retail and consumer (household and food service) levels.
  • Highlights of the report:
    • The report defines “food waste” as “food and the associated inedible parts removed from the human food supply chain”.
    • ‘‘Food loss” is defined as “all the crop and livestock human-edible commodity quantities that, directly or indirectly, completely exit the post-harvest/slaughter production/supply chain up to, and excluding, the retail level”.
    • It noted that in 2022, there were 1.05 billion tonnes of food waste generated (including inedible parts), amounting to 132 kilograms per capita and almost one-fifth of all food available to consumers.
    • Many low- and middle-income countries continue to lack adequate systems for tracking progress to meet Sustainable Development Goal 12.3 of halving food waste by 2030.
    • At present, only four G-20 countries (Australia, Japan, U.K., U.S.) and the European Union have food waste estimates suitable for tracking progress.
    • Hotter countries appear to generate more food waste per capita in households, potentially due to higher consumption of fresh foods with substantial inedible parts and a lack of robust cold chains.
    • As compared to urban areas, rural ones generally wasted less food, due to “greater diversion of food scraps to pets, livestock and home composting”.
    • As of 2022, only 21 countries had included food loss and/or waste reduction in their climate plans or Nationally Determined Contributions (NDCs).

Afanasy Nikitin Seamount
India recently applied to the International Seabed Authority (ISBA) for rights to explore two vast tracts in the Indian Ocean seabed, including a cobalt-rich crust long known as the Afanasy Nikitin Seamount (AN Seamount).

About Afanasy Nikitin Seamount: 

  • The AN Seamount is a structural feature in the Central Indian Basin, located about 3,000 km away from India’s coast.
  • It comprises a main plateau, rising 1200 m above the surrounding ocean floor (4800m). It is rich in deposits of cobalt, nickel, manganese, and copper.

What is a Seamount?

  • It is an underwater mountain formed through volcanic activity. These are recognised as hotspots for marine life.
  • Like volcanoes on land, seamounts can be activeextinctor dormant volcanoes.
  • These are formed near mid-ocean ridges, where the earth’s tectonic plates are moving apart, allowing molten rock to rise to the seafloor. The planet’s two most-studied mid-ocean ridges are the Mid-Atlantic Ridge and the East Pacific Rise.
  • Some seamounts have also been found near intraplate hotspots—regions of heavy volcanic activity within a plate—and oceanic island chains with volcanic and seismic activity called island arcs.
  • Significance of seamounts:
    • They provide information about the mantle’s composition and how tectonic plates evolve.
    • These are helpful in understanding their influence on how water circulates and absorbs heat and carbon dioxide.
    • They are good places for life because they can cause localised ocean upwelling, the process by which nutrient-rich water from deep within the ocean moves up to the surface.

About Solar and Heliospheric Observatory (SOHO): 

  • It is a project of international collaboration between the European Space Agency (ESA) and the U.S. National Aeronautics and Space Administration (NASA). It was launched in December 1995, SOHO was designed to study the Sun.
  • In order to provide continuous observations, it was maneuvered to orbit the first Lagrangian point (L1), a point some 1.5 million km (900,000 miles) from Earth toward the Sun where the gravitational attraction of Earth and the Sun, combine in such a way that a small body remains approximately at rest relative to both. 
  • It carries 12 scientific instruments to study the solar atmosphere, helioseismology and the solar wind. 
  • Though its mission was scheduled to run until only 1998, it has continued collecting data, adding to scientists' understanding of our closest star, and making many new discoveries, including thousands of comets. It is the longest-lived Sun-watching satellite to date.

South East Africa Montane Archipelago (SEAMA)
A recent study in southern Africa has unearthed a wealth of previously undocumented biodiversity in a newly recognised ecoregion called the South East Africa Montane Archipelago (SEAMA).

About South East Africa Montane Archipelago (SEAMA): 

  • It is a newly recognised mountainous ecoregion. It stretches across northern Mozambique to Mount Mulanje in Malawi, southern Africa’s second-highest mountain. 
  • The ecoregion encompasses 30 granitic inselbergs reaching > 1000 m above sea level, hosting the largest (Mt Mabu) and smallest (Mt Lico) mid-elevation rainforests in southern Africa, as well as biologically unique montane grasslands.
  • SEAMA has distinctly higher annual rainfall and humidity, especially in the dry season, compared to surrounding regions.
  • Since 2000, the SEAMA has lost 18% of its primary humid forest cover (up to 43% in some sites)—one of the highest deforestation rates in Africa. 
  • The major cause of montane forest loss in SEAMA is slash and burn shifting agricultural practices, typically used for subsistence food production by local communities, along with charcoal production, for household cooking, and as a source of revenue.

What are Inselbergs?

  • Inselberg, or Monadnock, is an isolated, steep-sloped ridge, hill, or small mountain that stands above well-developed plains. It appears like an island rising from the sea.
  • Inselbergs are generally erosional remnants. Often, inselbergs are composed of harder igneous rock (such as granite) that is more resistant to erosion. However, inselbergs may also form in sedimentary rocks.
  • These structures are one of several varieties of landforms called paleoforms that can survive with little modification for tens of millions of years.
  • In inselberg landscapes, the active erosional processes are confined to valley sides and valley floors.

What is Polar Vortex?
The polar vortex circling the Arctic is swirling in the wrong direction after surprise warming in the upper atmosphere triggered a major reversal event recently.

About Polar Vortex:

  • The polar vortex is a large area of low pressure and cold air surrounding both of the Earth’s poles. It weakens in summer and strengthens in winter. 
  • The term "vortex" refers to the counter-clockwise flow of air that helps keep the colder air near the poles.
  • Many times, during winter in the northern hemisphere, the polar vortex will expand, sending cold air southward with the jet stream.
    • This occurs fairly regularly during wintertime and is often associated with large outbreaks of Arctic air in the United States and Canada.
  • Portions of Europe and Asia also experience cold surges connected to the polar vortex. 
  • The polar vortex extends from the tropopause (the dividing line between the stratosphere and troposphere) through the stratosphere and into the mesosphere (above 50 km). 
  • Low values of ozone and cold temperatures are associated with the air inside the vortex.

Key Facts about Jet Streams:

  • Jet streams are narrow bands of strong wind that generally blow from west to east all across the globe.
  • Earth has four primary jet streams: two polar jet streams, near the north and south poles, and two subtropical jet streams closer to the equator.
  • What Causes Jet Streams?
    • Jet streams form when warm air masses meet cold air masses in the atmosphere.
    • The sun doesn’t heat the whole earth evenly. That’s why areas near the equator are hot and areas near the poles are cold.
    • So, when Earth’s warmer air masses meet cooler air masses, the warmer air rises higher in the atmosphere while cooler air sinks to replace the warm air. 
    • This movement creates an air current or wind. A jet stream is a type of air current that forms high in the atmosphere.
  • Since these hot and cold air boundaries are most pronounced in winter, jet streams are the strongest during both the northern and southern hemisphere winters.
  • On average, jet streams move at about 110 miles per hour. 
  • They are located about five to nine miles above Earth’s surface in the mid to upper troposphere, the layer of Earth’s atmosphere where we live and breathe.

What are Stomata?
Scientists recently discovered a novel regulatory mechanism that controls the opening of stomata in plants.

About Stomata:

  • They are tiny openings or pores in plant tissue that allow for gas exchange. They are typically found in plant leaves but can also be found in some stems. 
  • They allow a plant to take in carbon dioxide, which is needed for photosynthesis. They also help to reduce water loss by closing when conditions are hot or dry.
  • Stomata look like tiny mouths which open and close as they assist in transpiration. Plants that reside on land typically have thousands of stomata on the surfaces of their leaves. 
    • The majority of stomata are located on the underside of plant leaves, reducing their exposure to heat and air currents. 
    • In aquatic plants, stomata are located on the upper surface of the leaves. 
  • A stoma (singular for stomata) is surrounded by two types of specialized plant cells that differ from other plant epidermal cells. These cells are called guard cells and subsidiary cells.
  • Guard cells are large, crescent-shaped cells, two of which surround a stoma and are connected to at both ends.
    • A stomate opens and closes in response to the internal pressure of guard cells. These cells enlarge and contract to open and close stomatal pores.
    • Guard cells work to control excessive water loss, closing on hot, dry, or windy days and opening when conditions are more favourable for gas exchange. 
    • Guard cells also contain chloroplasts, the light-capturing organelles in plants.
  • Subsidiary cells, also called accessory cells, surround and support guard cells.
    • They act as a buffer between guard cells and epidermal cells, protecting epidermal cells against guard cell expansion.
  • For most plants, dawn triggers a sudden increase in stomatal opening, reaching a maximum near noon, which is followed by a decline because of water loss.

Moyar Valley
Moyar valley is the biggest nesting colony of critically endangered Gyps vultures in the wild.

About Moyar Valley:

  • Location: It extends from Gudalur through the core area of Mudumalai Tiger Reserve. This entire stretch is an important biome in the Nilgiri Biosphere Reserve.
  • It is sheltering several vital species like tiger and elephant and the critically endangered Gyps vulture. It is the only region in peninsular India where you have the biggest nesting colony of Gyps vultures in the wild.
  • How it supports Gyps population?
    • This valley offers plenty of wild kills and natural deaths of wildlife from Moyar village to Bhavanisagar.
    • This provides a stable food-chain to nature’s scavengers, simply because these carcasses are mostly free from NSAIDs (Non-Steroidal Anti-inflammatory Drugs) and other poisonous chemicals.

Quantum cryptography
Scientists are proposing new technology known as quantum cryptography to protect sensitive communications.

About Quantum cryptography:

  • It is also known as quantum encryption which uses the naturally occurring properties of quantum mechanics to secure and transmit data in a way that cannot be hacked.
  • It is completely secure against being compromised without the knowledge of the message sender or the receiver.
  • It is impossible to copy or view data encoded in a quantum state without alerting the sender or receiver. It uses individual particles of light, or photons, to transmit data over fiber optic wire.
  • Process:
    • Quantum cryptography is not replacing traditional cryptography; rather, it allows for a more secure transfer of the keys used in encoding and decoding.
    • The amount of information which can be transferred using quantum cryptography is not very large or very fast, but it is very secure.
    • The maximum speed, scale and security of the transfer is achieved by sending the secret key using quantum coding, but encoding and sending the data itself using traditional methods and algorithms.
  • Benefits of quantum cryptography
    • Provides secure communication:  Instead of difficult-to-crack numbers, quantum cryptography is based on the laws of physics, which is a more sophisticated and secure method of encryption.
    • Detects eavesdropping:  If a third party attempts to read the encoded data, then the quantum state changes, modifying the expected outcome for the users.
    • Offers multiple methods for security: There are numerous quantum cryptography protocols used. Some, like QKD, for example, can combine with classical encryption methods to increase security.

Investment Facilitation for Development (IFD)
One of the significant developments at the 13th Ministerial Conference (MC13) of the World Trade Organization (WTO) in Abu Dhabi was the non-adoption of the agreement on Investment Facilitation for Development (IFD).

About Investment Facilitation for Development:

  • It is a joint Initiative launched at the 11th WTO Ministerial Conference (MC11) in December 2017 on a plurilateral basis by 70 countries. This was done through a process known as the Joint Statement Initiative.
  • Aim: This agreement aims to create legally binding provisions to facilitate investment flows. It also aims to develop predictable, transparent and open investment rules that will contribute to more efficient investment flows and increased business confidence and it is now in a formal negotiation phase. 
  • Objective: A core objective of the framework is to facilitate greater participation by developing and least-developed WTO Members in global investment flows.
  • The IFD agreement was finalised in November 2023 and at present around 120 of 166 WTO member countries (more than 70% of the membership) back this agreement.
  • Key areas included in the IFD Agreement to promote and facilitate investment
    • Improving regulatory transparency and predictability: such as publishing investment-related measures and establishing enquiry points;
    • Streamlining and speeding up administrative procedures: such as removing duplicative steps in approval processes and simplifying applications;
    • Enhancing international cooperation and addressing the needs of developing members – such as providing technical assistance and capacity-building for developing countries and least developed countries; and
  • India is not a part of this initiative.

What are Treasury Bills?
Recently, the Government of India, in consultation with the Reserve Bank of India notified the calendar for the issuance of Treasury Bills for the quarter ending June 2024.

About Treasury Bills:

  • Treasury bills or T-bills are money market instruments. These are short term debt instruments issued by the Government of India.
  • Maturity period: At present, treasury bills are issued in three maturities — 91-day, 182-day and 364-day.
  • These are zero coupon securities and pay no interest. Instead, they are issued at a discount and redeemed at the face value at maturity.
  • Who can buy?
    • Individuals, trusts, institutions and banks can purchase T-Bills. But they are usually held by financial institutions.
    • Banks give treasury bills to the RBI to get money under repo. Similarly, they can also keep it to fulfil their Statutory Liquid Ratio (SLR) requirements.
  • How do T-bills work?
    • Treasury bills are issued at a discount to original value and the buyer gets the original value upon maturity. For example, a Rs 100 treasury bill can be availed of at Rs 95, but the buyer is paid Rs 100 on the maturity date.
    • The return on treasury bills depends on the liquidity position in the economy. When there is a liquidity crisis, the returns are higher, and vice versa.

Mushk budiji Rice
Recently, scientists reported that altitude and temperature play an important role in the development of mushk budiji aroma.

About Mushk budiji Rice:

  • It is short, bold aromatic rice grown in the higher reaches of Kashmir valley. It possesses a harmonious blend of taste, aroma and rich organoleptic properties.
  • It is mainly grown in areas of Sagam, Panzgam and Soaf Shali of district Anantnag.
  • The consumption of aromatic rice in Kashmir has now been limited to special occasions, marriages and festivals. It has received a Geographical Indication (GI) tag.

Highlights of the study:

  • Scientists conduct a study of selected locations on the flavour profile of mushk budiji using gas chromatography-mass spectroscopy (GC-MS) and an ‘electronic nose’.”
  • Based on these studies, the scientists identified 35 volatile organic compounds (VOCs) in mushk budiji rice samples.
  • Acetyl-1-pyrroline (2-AP) is a known aromatic compound found in some varieties – but it was present only in mushk budiji samples collected from higher altitudes.

What is Chromatography-mass spectroscopy?

  • It is an analytical method used to reveal the presence of volatile compounds present in organic mixtures extracted from geological, environmental and biological samples.
