Green pepper belongs to the plant kingdom, Dicotyledonous, Chrysanthemum Subclass, Solanaceae. And red pepper are collectively referred to as peppers. Fruit is a berry. There are many aliases, such as big pepper, lantern pepper and persimmon pepper. Because it can bear sweet berries, it is also called sweet pepper and vegetable pepper. Annual or perennial herbs, characterized by large fruits and mild or not spicy taste, are used as vegetables instead of seasonings. Because of its bright green color, the newly cultivated varieties have many colors such as red, yellow and purple, which can be widely used not only as a dish, but also as a side dish. Green pepper is evolved from pepper native to tropical areas of Central and South America. After long-term cultivation, domestication and artificial selection, the fruit size changed, the pulp became thicker, the spicy taste disappeared, and the number of carpels and ovary cavities increased. Green pepper was introduced to China more than 100 years ago, and was widely planted all over the country. Green pepper is rich in vitamin C, which is suitable for people with hypertension and hyperlipidemia.
