Embodiment

[0026] A method for preparing a sunflower seed polypeptide, the method comprising the steps of:

[0027] a. Processing of raw materials: crush the defatted sunflower seed cake with a pulverizer and pass through a 40-mesh sieve to obtain crushed sunflower seed cake, and then mix the crushed sunflower seed cake with water in a ratio of 1:4 by weight to prepare Obtain a sunflower seed cake suspension.

[0028] b. Homogenization of the suspension: the sunflower seed cake suspension is subjected to colloidal grinding and then homogenized by a high-pressure homogenizer to obtain a sunflower seed cake mixture, and the homogenization pressure is 30Mpa.

[0029] c, heat preservation enzymolysis: add the mixed enzyme solution of AlcaLase enzyme and papain in the sunflower seed cake mixed solution,

[0030] The volume ratio of AlcaLase enzyme and papain in the mixed enzyme solution is AlcaLase enzyme: papain = 1:1. The amount of mixed enzyme solution added is 0.05% of the mass of the mi...

Abstract

The invention provides a preparation method of sunflower seed polypeptide, comprising the following steps: a, processing of raw materials: uniformly mixing water and a sunflower seed cake crushed material, which is obtained after a low-temperature cold-pressed sunflower seed cake is crushed, so as to obtain a sunflower seed cake suspension; b, homogenization of the suspension: homogenizing the sunflower seed cake suspension to prepare a sunflower seed cake mixed liquor; c, thermal-insulation enzymatic hydrolysis: adding a mixed the sunflower seed cake mixed enzyme liquid of AlcaLase enzyme and papain into the sunflower seed cake mixed liquor to carry out enzymatic hydrolysis at the temperature of 50-60 DEG C at pH of 7.0-8.5 for 6-8h so as to prepare a sunflower seed cake enzymatic hydrolysate; d, high temperature sterilization: rapidly heating the sunflower seed cake enzymatic hydrolysate to 90-95 DEG C; e, liquid-solid separation: carrying out liquid-solid separation on the sunflower seed cake enzymatic hydrolysate which has undergone high-temperature enzyme deactivation and removing insoluble solids so as to prepare a sunflower seed polypeptide liquid; f, condensation: condensing the sunflower seed polypeptide liquid to prepare a sunflower seed polypeptide concentrate; and g, drying: drying the sunflower seed polypeptide concentrate so as to obtain a sunflower seed polypeptide powder.

Description

technical field [0001] The invention belongs to the field of food processing, in particular to a preparation method of sunflower seed polypeptide. Background technique [0002] The phospholipids in sunflower seeds have a good health care effect on the cranial nerves. The extracted sunflower oil contains a large amount of unsaturated fatty acids, which has the effect of preventing and curing arteriosclerosis [5] . Sunflower seeds contain zinc, manganese, chromium and other indispensable trace elements for the human body, which can supplement the decreasing zinc and manganese content in the aging process of the human body. The protein content of sunflower seeds is generally 14% to 17%, and the highest can reach 29.7%. Its potency is similar to that of animal protein, and it is a good protein. my country's sunflower seeds are very rich in resources, but the depth of current development and utilization is far from enough. It is limited to the production of primary food, and t...
