FSSAI Announces Curbs on Dairy Products
|
Context: The Food Safety and Standards Authority of India (FSSAI) has recently issued a directive to food businesses to remove claims related to ‘A1’ and ‘A2’ types of milk from their product descriptions.
Overview of Classification Of Dairy Products As ‘A1’ and ‘A2’:
- Classification: Several FBOs (Food Business Operators) are selling milk and milk products in the name of A1 and A2.
- Recognition of Classification: FSSAI regulations do not officially recognise this distinction, leading to the current mandate to eliminate these claims.
- Differentiation: Based on the structural differences in beta-casein protein.
- Beta-Casein: It is one of the major proteins found in milk, and it comes in two main variants: A1 and A2.
- Historically, cows produced only A2 beta-casein.
- However, due to genetic mutations, some cows began to produce A1 beta-casein as well.
- Key Difference: It lies in the amino acid structure.
- A1 beta-casein has a histidine amino acid at position 67.
- While A2 beta-casein has proline at the same position.

Tanager-1

|
Context: Recently, Tanager-1 satellite was launched from California, USA.
About Tanager-1 Satellite:
- Purpose: To track methane and carbon dioxide emissions.
- Imaging Spectrometer Technology: It will track these emissions by measuring hundreds of wavelengths of light that are reflected by Earth’s surface.
- Significance: It will be able to measure point-source emission on a global scale.

Sonoluminescence
|
Context: Sonoluminescence (SL) is a scientific phenomenon that occurs when a gas bubble in a liquid emits light after being subjected to intense sound waves.
About Sonoluminescence:
- Discovery: In 1934, two German engineers studying sonar technology discovered a curious phenomenon.
- Phenomenon: They observed that when a small bubble in a liquid is exposed to powerful sound waves, it emits a flash of light.
- Mechanism:
-
- Sound waves create alternating high- and low-pressure phases.
- These phases cause the bubble to rapidly expand and collapse.
- During collapse, the bubble compresses intensely, causing internal temperatures to soar to several thousand kelvin.
- The extreme temperature causes gases within the bubble to ionise.
- This ionisation releases light energy in about a trillionth of a second.
- The exact mechanism of light production is still unknown.
Natural Occurrence in Pistol Shrimp:
- Pistol Shrimp (Family Alpheidae):
- Possess a specialised claw capable of snapping shut at incredible speed.
- This action creates a jet of water that forms a low-pressure bubble.
- The bubble’s collapse produces a loud sound, intense heat, and sometimes a brief flash of light.

RHUMI-1

|
Context: India launched its first reusable hybrid rocket ‘RHUMI- 1’, developed by the Tamil Nadu-based start-up Space Zone India with Martin Group, from Thiruvidandhai in Chennai.
About RHUMI-1:
- Hybrid Rocket Engine: The RHUMI Rocket is equipped with a generic-fuel-based hybrid motor.
- Hybrid systems improve efficiency and reduce operational costs.
- Adjustable Launch Angle: The rocket’s launch angle can be precisely adjusted between 0 to 120 degrees.
- Parachute System: It is equipped with an electrically triggered parachute deployer.
- Environmentally Friendly: RHUMI is 100% pyrotechnic-free and 0% TNT.
- Application: The rocket’s applications extend beyond space exploration, impacting fields such as agriculture, environmental monitoring, and disaster management.
