通过考察欧、美几个稻谷加工厂,以及日本、韩国等发达国家米糠蛋白制取的先进工艺,整理出工业化米糠蛋白制取的工艺:脱脂米糠经过两次浸出和分离后,米糠蛋白溶解于液相中,液相进行酸沉分离提取出米糠蛋白,再对米糠蛋白进行杀菌和干燥,从而获得了优质的食用米糠蛋白。 相似文献

Abstract Qualitative and quantitative aspects of proteins, carbohydrates, lipids, vitamins, minerals, and antinutritional factors in rice bran and its subfractions are described. The nutritional value measured in animal feeding tests is summarized for bran, defatted bran, stabilized bran, and protein concentrates derived by alkaline extraction of bran. Stabilization of rice bran and how this process may lead to a quantum change in its utilization in foods and for recovery of edible oil is discussed. Present uses of rice bran in foodstuffs are described. 相似文献

从原料米糠中分离出纯稻米胚和纯米糠,利用溶剂浸出法分别提取其中油脂并进行品质分析对比,以研究稻米胚及米胚油的营养品质。结果表明:稻米胚粗脂肪含量27.06%,粗蛋白含量19.50%,粗纤维含量4.88%,比米糠粗脂肪、粗蛋白含量明显提高,粗纤维含量降低;米胚油的酸值(KOH)、过氧化值、维生素E含量、谷维素含量、植物甾醇含量分别为21.7 mg/g、6.1 mmol/kg、43.18 mg/100 g、0.47%、3.07%,与米糠油相比,米胚油的酸值(KOH)降低了23.8 mg/g,过氧化值降低了1.7 mmol/kg,维生素E含量提高了17.18 mg/100 g,植物甾醇含量相差不大,谷维素含量降低0.93个百分点。米胚油在酸值和维生素E含量方面较米糠油具有明显优势,新鲜稻米胚既可以直接作为营养丰富的产品,也是优质食用油的原料。 相似文献

Rice bran oil is not only a nutritious vegetable oil, but also a specialty oil with unique properties and many health benefits. Good stability, appealing flavor and long fry-life enable rice bran oil be used for frying and also to make margarine and shortening and advanced nutritional oils. More importantly, rice bran oil has been reported to have a high potential for making pharmaceuticals and cosmeceuticals. Rice bran oil has surprisingly high levels of nutraceutical components, such as oryzanol, fat-soluble vitamins, sitosterol, other plant sterols and other nutrients. Thus, rice bran oil has been a study focus in relation to its function and application in many countries in the world, as well as a family’s daily health edible oil. This paper summarizes the research progress on the bioactive ingredients and the physiological activities of rice bran oil. 相似文献
