玉米又称玉蜀黍,是世界三大粮食作物之一,又是重要的饲料来源,在农业生产中占有重要的地位。我国玉米的种植面积约为2亿多亩,占世界种植面积的15.1％;年产量8500万吨,居世界第二位。 玉米胚芽是玉米中营养成分最好的部分,是玉米籽粒发育生长的起点。玉米胚芽集中了玉米中84％的脂肪,83％的无机盐,65％的糖和22％的蛋白质,此外还含有磷脂,谷固醇等。一吨玉米籽粒约可分离出10公斤左右的玉米胚。玉米胚芽油(或称玉米油)是一种有较高营养价值的植物油,国际上把玉米油称为保健油,其销售价格也高于其它食用植物油脂,国外像印度、加拿大、美国等均有生产玉米油的传统。玉米胚的含油率达40～50％,我国每年浪费掉的玉米胚芽就达几十万吨,也就等于白
Corn, also known as maize, is one of the world’s three major food crops and an important source of feed. It occupies an important position in agricultural production. The planting area of corn in China is about 200 million mu, accounting for 15.1% of the world’s planting area; the annual output is 85 million tons, ranking second in the world. Corn germ is the best part of corn and it is the starting point for the development of corn kernels. Corn germ concentrates 84% of fat in corn, 83% of inorganic salt, 65% of sugar and 22% of protein, and also contains phospholipids, gluten and so on. About a kilogram of corn embryos can be separated from a ton of corn kernels. Corn germ oil (or corn oil) is a kind of vegetable oil with higher nutritional value. Internationally, corn oil is called health oil. Its sales price is also higher than other edible vegetable oils. Foreign countries like India, Canada, and the United States are all There is a tradition of producing corn oil. The oil content of corn embryos is 40-50%, and the annual wasted corn germ in China is hundreds of thousands of tons, which is equivalent to white.
