These days, dried herbs and spices are widely available in supermarkets. But it is better to purchase them from local spice stores in your area as their collection of dried herbs and spices are of a superior quality and comparatively fresher than those offered by regular markets. When purchasing turmeric, always prefer organic turmeric as it does not possess additives.

The color of turmeric varies greatly, and it is important to choose the correct turmeric powder. Often, turmeric is mixed with other ingredients to give it a yellow–red hue. Being a natural colorant, it is also used by industrial workers to ward off the risks that may arise from the usage of artificial coloring material. The turmeric in curry powder has the highest content of curcumin, averaging about 3.14 % in weight. Turmeric is available both in chunks as well as powder and should be purchased after verifying the freshness and quality.
