What is Turmeric?

Turmeric has been cultivated in India and other countries for the past 2500 years. It was introduced to China by India in 700 AD. Slowly and gradually, other countries started cultivating turmeric. It is an Indian spice, which is made by grinding the roots of Curcuma Longa plant or curcumin. It is yellow in colour and adds special flavour and colour to the food. It also acts as an excellent antibiotic. The curcumin content in turmeric helps fight infections.

What happens when turmeric comes in contact with detergent?

Turmeric has a pigment known as xanthophylls, which lends the yellow colour to it. It also has a pigment called as carotene, which is reddish orange in colour. When turmeric comes in contact with detergent, it reacts with the fatty acids present in the detergent and hence the carotene pigment gets more active than the xanthophylls and turmeric turns red. When turmeric is combined with any base liquid like soap it turns red in colour while when turmeric comes in contact with any substance like that of vinegar, that is acidic in nature, it turns yellow.
