玉米胚芽资源在国内比较丰富,其含油量及蛋白含量较高.目前用传统方法提取玉米胚芽油,为提高产油率,采用高温榨油技术,使胚芽蛋白变性,所产生的大量玉米胚芽饼粕,只能用低价值的动物饲料.本实验采用玉米胚芽低温干燥、低温破碎和预榨、低温萃取脂肪的工艺,目的在于使玉米胚芽提取脂肪过程,能保持玉米胚芽蛋白不变性.因而用低温萃取后的胚芽饼粕,可用常规碱溶、酸沉法提取玉米胚芽蛋白粉.这种胚芽蛋白粉,含有一定量百分比的赖氨酸、蛋氨酸、苏氨酸、色氨酸、缬氨酸、L苯丙氨酸亮氨酸、异亮氨酸8种必需氨基酸,符合国际粮油/卫生组织所规定的优质蛋白标准,接近于母乳和蛋清蛋白的营养价值.此技术能于工业上采用,将会大大提高玉米胚芽加工业的经济效益.

The corn germ resources in China is abundant and its full of oil and protein.Traditional extraction method was performed at high temperature,this bringsa large number of corn germ meal which can only be used as a low-value animal feed.In this paper,we discuss a new extraction method includes low-temperature drying,crushing and pre-extrusion and low-temperature fat extraction process.The method can best keep the corn protein.Therefore,after low temperature extraction,high quality protein can be obtained by alkali and acid precipitation from the corn germ meal.This kind of corn germ protein mill,containing certainpercentage of eight amino acids,such aslysine,methionine,tryptophan,threonine,valine,L phenylalanine leucine,isoleucine and meets with the international FAO/WHO stipulated standards of quality protein.The nutrition value of the corn germ protein mill is close to human's milk protein and whey protein.This technique can be used in the industry to greatly improve the economic value of corn germs.
