BLACK PEPPER (Piper Nigrum, active ingredient: Piperine) is a flowering vine in the family Piperaceae, cultivated for its fruit which is usually dried and used as a spice and seasoning, known as a peppercorn. When fresh and fully mature, it is approximately 5 millimetres (0.20 in) in diameter and dark red, and contains a single seed like all drupes. Peppercorns and the ground pepper derived from them may be described simply as pepper, or more precisely as black pepper (cooked and dried unripe fruit), green pepper (dried unripe fruit), and white pepper (ripe fruit seeds).
Black pepper is native to south India and is extensively cultivated there and elsewhere in tropical regions. Currently, Vietnam is the world’s largest producer and exporter of pepper, producing 34% of the world’s Piper nigrum crop as of 2013.
Dried ground pepper has been used since antiquity both for its flavour and as a traditional medicine. Black pepper is the world’s most traded spice and is one of the most common spices added to cuisines around the world. Its spiciness is due to the chemical piperine, not to be confused with the capsaicin characteristic of chili peppers. It is ubiquitous in the modern world as a seasoning and is often paired with salt.
