The word Spices, needs no introduction, attributing to its familiarity among all the human communities, especially among food freaks. Spices are part of daily human use. As per the layman knowledge, spices are the ingredients used in the preparation of the food to enhance its taste.

Spices are available from different parts of the plants. Most of the spices are either dried fruits or berries or seeds of a plant. Some of the spices are also from roots, rhizomes, barks, arils, flower buds, stigmas, resins, etc. Unlike other food ingredients, spices are often added in minute quantities while preparing delicacies. The essential oils present in the cells of these plant parts are responsible for adding flavor, aroma and color to the food. Every spice has its own essential oil, which has different chemical compounds in different proportions. Spices can perform their function by releasing essential oils, for which the spices have to be crushed and then used. As these oils are volatile, they tend to spread in the dish as soon as they are crushed and added.
