Broccoli is an important crop worldwide, with over 21 million tons produced annually. It is considered a functional food due to its high nutritional value and bioactive compounds. There are two main types of broccoli - heading broccoli which forms curds and sprouting broccoli which has loose flower buds on stalks and is more popular in India.
