Abstract: Peppery element is a kind of high-quality natural red pigment. It can be extracted from dry red peppers. Peppery element has applications in the fields of medicine food, light industry and so on. We studied the elimination of peppery element and extraction of peppery pigment from the dry pepper. Effect about extraction rate of peppery pigment and technical conditions of eliminating peppery element were approached. The results showed: When 15% NaOH solution extracts for 1. 5h at 90℃,peppery element will be eliminated; By the orthogonal test, the best extraction conditions are found: ① The extraction time is 3h, the extraction temperature is 30℃, the acetone volume is 25ml for 1g hot red pepper, and the extraction times is 3. ②The technology of peppery element extraction was studied by the way of using yield as an index. The amount of the solvent (per 10.0g paprika red pigment) was 120ml, the extraction time was 1 hour. Compared with traditional extraction method, the mix preparation method could improve the extraction yield and save extraction time of paprika red. The best extraction is 3.67%.
