The products developed from pepper broadly fall into four groups: black pepper, white pepper, green pepper and oil and oleoresin of pepper. Black pepper is the whole dried fruit of the plant, while white pepper is the dried seed after removing the pericarp of the berries. White pepper is neither too hot nor too cold, and is supposed to be the best of all peppers. Black as well as white pepper, are widely used as food ingredients, and as flavouring agents for a variety of processed foods.
