Abstract

This studies were conducted to find out the possibility of utilizing red pepper seed as resources of food fats, the research method was designed to make a comparison between crude and refined oil, and the results of the studies are as follows : The red pepper seed contained 28% of crude fat and 21% of crude protein. The main fatty acids of red pepper seed oil were linoleic acid(72.10~72.31%), palmitic acid(12.81~13.28%) and oleic acid(9.47~10.48%). The linolenic acid content was so small that is will not influence the autoxidation of the red pepper seed oil. The major triglyceride type of crude and refined oil of red pepper seeds were C52 and C54. The other types were found in a small quantity. The sterol composition of crude oil was $\beta$-sitosterol, campasterol, stigmasteral and brassicasterol,in the quantity order. after refining, brassicasterol was not detected, and the content was decreased by one six and one eight. The toropherol composition of crude and refined oil, tocopherol analog was composed of three kinds $\alpha$-, ${\gamma}$-, $\delta$-, but no $\beta$-form. the quantity of ${\gamma}$-, $\alpha$- and $\delta$-tocopherol were 162.91, 83.72, 43.98mg% respectively. The Quantity of and capsaicin in crude oil was 1,296 ppm, and it was reduced consicerably by refining and removed completely after the process of redeodorization.
