FSSAI Announces Curbs on Dairy Products

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

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

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

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.
