Process for extracting both active embryonic peptide and natural corn oil from embryo bud of corn

Abstract

A process for preparing the active embryonic peptide with coproduct of corn oil from the embryo bud of corn at the same time includes such steps as wet and thermal pretreating, grinding by colloid mill, multi-stage zymolysis, centrifugal separation to obtain fibres, corn oil and milk, concentrating the milk by nanometre filtering membrane, further concentrating, homogenizing, emulsifying, drying and granulating.

Description

1. Technical field:

[0001] The invention relates to a deep processing method of corn germ, in particular to a method for preparing germ active peptide and natural corn oil from corn. 2. Background technology:

[0002] At present, the processing and utilization of corn germ at home and abroad is limited to separating the germ in corn, drying it to obtain corn oil through traditional pressing or leaching, and selling the germ cake at a low price as feed after oil extraction. Corn is known as the "golden crop" in the world because of its multi-nutrition, and corn germ is the essence of corn "gold in gold". The fat in the germ mainly exists in the form of glycerol fatty acid, and the unsaturated fatty acid in the fatty acid accounts for more than 86%. The protein in the germ is a full-price high-quality protein, with as many as 18 kinds of amino acids. Among them, the content of essential amino acids for the human body has reached the standard of high-quality protein set by the...
