Turmeric powder can be adulterated in many different ways:
- Curcuma longa(Turmeric) is a strong base and is used as a domestic product.
The possible adulteration and deterioration of Curcuma longa are as follows:
- It can be mixed with chalk powder which results in production of small bubbles.
- When turmeric powder is mixed with water, it produces some streaks of soluble colour in water that is caused as a result of adulteration of lead chromate in turmeric powder.
