Penentuan Kondisi Optimum untuk Mempertahankan Mutu Bekatul melalui Penghambatan Aktivitas Lipase oleh Protease Komersial

Abstract

Rice bran is a by-product of milling process that contains protein and high essential components i.e. lysine, antioxidant, fiber, mineral and vitamin E. It makes rice bran have high potential for substitute material of foodstuffs. The use of rice bran as food and feed is limited, however, by its instability caused by hydrolytic and oxidative rancidity. Immediately following the milling process, rapid deterioration of the crude fat in the bran by lipase and, to a lesser extent, oxidase occurs and makes the bran unfit for human consumption. The naturally occurring lipase enzyme in the ric" bran hydrolyzes triglycerols, which are primary lipids.
