AI:Lit the various kind of adulteration that is found in the milk all around the globe today since last 5 thousands years especially in US,UK,Canada, Europe, Middle East, Russia,China,Asia,Oceania. Which AI automated machines are available to avoid these adulteration and mixing of the adulterated substances and chemicals and purify it in real time if adulterated using both natural and scientific methodologies in real time.

 Milk adulteration is a widespread issue across the globe, and various adulterants have been used in milk for thousands of years. The adulteration of milk involves adding harmful or non-authentic substances to milk to increase its quantity, extend its shelf life, or enhance its appearance. In the past few decades, there has been growing concern over the use of dangerous chemicals and other substances in milk. The adulterants can range from natural substances like water to highly harmful chemicals that may be dangerous for human consumption.

Common Adulterants in Milk Across the World

1. Water:

• Water is added to milk to increase the volume. It dilutes the milk and reduces its nutritional value.
• Common in: All regions, particularly in developing countries.

2. Starch:

• Starch, derived from substances like rice, wheat, or potato, is often added to milk to increase its viscosity.
• Common in: South Asia, Middle East.

3. Detergents:

• Detergents such as washing soda or soap powders are added to milk to increase its froth or for other purposes.
• Common in: India, Pakistan, Bangladesh, and parts of Africa.

4. Synthetic Milk (Chemical Milk):

• This is the milk produced from non-dairy fat like palm oil or other chemicals to mimic the properties of milk.
• Common in: South Asia, China.

5. Formalin:

• Formalin (formaldehyde) is sometimes used to preserve milk, as it can prevent bacterial growth.
• Common in: Southeast Asia, China, and parts of South Asia.

6. Urea:

• Common in: South Asia and Southeast Asia.

8. Harmful Preservatives (e.g., Hydrogen Peroxide):

• These chemicals are used to extend the shelf life of milk, but they can be harmful when consumed.
• Common in: Europe, parts of the Middle East, and South America.

9. Sodium Bicarbonate (Baking Soda):

• This is used to reduce the acidity of milk, creating an impression of fresh milk.
• Common in: South Asia, Middle East.

10. Synthetic Milk Proteins (Casein or Whey Proteins):

• Sometimes, synthetic milk proteins are used to mimic the composition of real milk.
• Common in: Asia, especially China.

11. Melamine:

• Common in: China (notably the 2008 Chinese milk scandal).

12. Antibiotics and Hormones:

• Hormones such as recombinant bovine growth hormone (rBGH) are used to increase milk production, while antibiotics are used to prevent infections in dairy cows.
• Common in: US, UK, Canada, and Europe.

AI-Driven Solutions to Detect Milk Adulteration in Real-Time
