Food Adulteration analysis techniques. How to?

I need to know how to test food products for adulteration. These days companies in India are mixing various chemicals in food product to increase production and serve bigger population. They just want to make money and local government and police dont do a single thing to stop them because they get bribe.

Very few people and NGO have taken the task for testing food but considering huge population of India, they are very few.

I had learnt some basic techniques back in school but want to learn as much as I can.

some common food adulterations here:-

1-milk+fertilizers+water (we don't get pure milk)

2-fruits+carbonates (to ripe fruit faster)

3-honey+antibiotics+fertilizers (antibiotics pass down to honey from medicated bees)

4-Butter and fat products + dead animal fats ( dead animals include dead stray dogs, cattle, others) - horrible process done by boiling dead animals in large cylinders for hours

5-cooking oil +fertilizers

6- Many undiscovered adulterations.

If you know about any incidence of adulteration in your native area, please do share.
