Turmeric (Curcuma Longa) is a flowering plant of the ginger family.
Turmeric's roots (rhizomes) are used in cooking, in the form of powder, being one of the key ingredients in many Asian dishes, imparting a mustard-like, earthy aroma and pungent, slightly bitter flavor to foods.
Turmeric powder was used widely from ancient times for both food and dye (for its golden yellow color) as well as an organic, vegetal, natural food colorant, being sometimes called 'Indian saffron'.
The golden yellow color of turmeric is due to curcumin.
Turmeric Powder (Curcuma Powder) is used in many products such as canned beverages, baked products, dairy products, ice cream, yogurt, yellow cakes, orange juice, biscuits, popcorn color, cereals, sauces, and gelatin, to impart a golden yellow color.
It is a principal ingredient in curry powders.
Turmeric is our preferred choice for coloring yellow pasta.
