Abstract

The invention discloses a manufacturing method of flax protein in the edible protein manufacturing technical domain, which comprises the following steps: degreasing under low temperature; grinding; doing aqueous extract and centrifugal separation; extracting through salt; doing centrifugal separation; condensing in the vacuum; spraying; drying. The invention solves the defect of high denaturization degree, deep glaze and bad taste, which improves the protein content of flax protein at 55-70%.

Description

1. Field of invention: [0001] The invention relates to a method for producing flax protein from oily plants with high oil content, and belongs to the technical field of edible protein processing methods. 2. Background technology: [0002] Oil-seed protein is a kind of oil-seed protein produced after degreasing and further processing of oil-seeds. Flaxseed is rich in protein and oil resources. Flax protein is rich in nutrition, rich in various amino acids needed by the human body, easy to be absorbed by the human body, and is a high-quality protein that combines functionality and nutrition. For a long time, flax protein has not been well utilized. Because its protein is composed of 2S components, it is difficult to extract with a single solvent, and the extraction rate is low. It is only used as feed. In view of this, it is an urgent problem for scientific and technological workers to develop a method for deep processing and producing flax protein under the premise of maint...
