摘　　要：玉米综合开发有许多产品。玉米蛋白质、油脂提取新工艺在用９５％酒精提取玉米油的同时干燥酒精，得到无水酒精产品。然后用酒精－碱提取蛋白质，得到的淀粉发酵制酒精，形成了酒精的循环使用。该新工艺与传统脱胚制油工艺相比明显的特点是玉米油提取率高达９０％以上，其全玉米蛋白质浓缩物含粗蛋白达７５％－８０％，其氨基酸含量及组成均优于传统玉米蛋白粉。The comprehensive exploitation of corn have many products,the extraction processing simultaneously dehydrated ethanol and extracted more than 90% of crude oil from dried corn,produced dehydrated ethanol.Protein was extracted by using a mixture of alkali and ethanol,the starch was used as substrate for ethanol fermentations.The procedure provided a menas for recycling the alcohol from ethanol fermentation to upstream steps of protein and oil extractions.The freezedried corn protein extracts contained 75%80% crude protein.
