It is a common practice at home and abroad to use Chili essence as food seasoning. Because it is inconvenient to use pepper directly in food production, and the spicy degree of pepper is limited, many products use pepper essence to improve the spicy degree at present. The so-called "Chili essence", the scientific name "Chili oleoresin", is a product extracted and concentrated from pepper, which has a strong spicy taste.

The essence of capsicum contains capsaicin, protein, pectin, polysaccharide, capsanthin and other substances besides its spicy ingredients. Capsaicin is just a vague business name. All products containing capsaicin-like extracts are called capsaicin, and the content can vary greatly.

Even natural pepper ingredients, excessive use may be harmful to health. It is precisely because capsaicin is the concentrated product of spicy substances in pepper, which can produce a high degree of spiciness that natural pepper can't compare with, so it does more harm to mucosa, and people who pursue spicy stimulation should not be careless.

In addition, when the skin, eyes, mouth, respiratory tract and digestive tract are damaged, inflamed or ulcerated, don't try food containing capsaicin. After touching, don't rub your eyes for a period of time to avoid unnecessary pain.
