Method for synchronous extraction of grease and protein peptide from shiny-leaved yellowhorn

Abstract

The invention discloses a method for synchronous extraction of grease and a protein peptide from shiny-leaved yellowhorn, and belongs to the technical field of plant grease and protein processing. The method includes the following steps: (1) peeling shiny-leaved yellowhorn, then crushing, and next carrying out vacuum extrusion expanding treatment, to obtain an expanded product; (2) adding water in the expanded product and mixing, then adding protease, carrying out magnetic field strengthening enzymolysis, and after enzymolysis, carrying out centrifugal separation to obtain free oil, a hydrolysate, an emulsion and residues; (3) mixing the emulsion with water, then adding phospholipase, carrying out ultrasonic enzymolysis demulsification, and after demulsification, carrying out centrifugal separation to obtain free oil and a hydrolysate; (4) merging the hydrolysates, then adjusting a pH to be neutral, then successively carrying out ultrafiltration treatment and nanofiltration treatment, and carrying out spray drying of the filtrate to obtain a protein peptide powder; and (5) washing the residues, carrying out vacuum drying, and crushing to obtain an animal feed. The shiny-leaved yellowhorn oil prepared by the method has high extraction rate and good quality, and the shiny-leaved yellowhorn protein peptide having high purity and strong activity also can be obtained at the same time and can be applied to industrial production with certain scale.

Description

technical field [0001] The invention belongs to the technical field of vegetable oil and protein processing, and mainly relates to a method for synchronously extracting oil and protein peptides from sorbifolium sorbifolium. Background technique [0002] Xingguan fruit has high nutritional value, the oil content of seeds is 30.4%, and the oil content of kernels after peeling is as high as 66.39%, of which the unsaturated fatty acid content is as high as 94%, linoleic acid accounts for 36.9%, oleic acid accounts for 57.16%, Compared with olive oil and soybean oil, it has higher nutritional value and can effectively prevent hypertension, hyperlipidemia, arteriosclerosis and other diseases. In addition, sorbifolia also contains 25.75% protein, which is a plant protein with high nutritional value. It is rich in amino acids and has a balanced amino acid ratio, which is better than peanut protein. At the same time, sorbifolia protein has better functions. sex. [0003] At present...

Problems solved by technology

The pressing method has a simple process and less supporting equipment, which can maintain the special flavor of the product, but the oil extraction rate is low, the energy consumption is high, and the cost is high. Moreover, the protein denaturation of the cake after pressing is serious, and the protein utilization rate is low, resulting in a serious waste of vegetable protein.

The leaching method has high production efficiency and low residual oil rate, but this method requires a lot of equipment, large investment, large loss of oil flavor and residual organic solvents, and requires refining treatment, which will also pollute the environment
