specific Embodiment approach 1

[0020] Embodiment 1: The preparation method of the linseed meal polypeptide beverage provided in this embodiment is carried out according to the following steps:

[0021] 1. Crush flax meal and pass through a 60-mesh sieve, accurately weigh 10g of flax meal powder into a 500ml beaker, add distilled water according to the weight of flax meal: water volume 1:8-18, and add the weight of flax meal after mixing evenly 0.5-2% cellulase, adjust the pH value to 4.8 with 1mol / L NaOH or 1mol / L HCl, keep the temperature in a 50°C water bath for 1.5-4 hours, then inactivate the enzyme to obtain the linseed meal cellulase treatment solution.

[0022] The cellulase is from Jiangsu Ruiyang Biotechnology Co., Ltd., and the cellulase activity: 50,000 U / g.

[0023] Two, in the linseed meal cellulase treatment liquid that obtains in step 1, add the alkaline protease of 1~3.5% of linseed meal weight, adjust pH value 8~10 with 1mol / L NaOH or 1mol / L HCl, at 50~70 Keep the temperature in a water ba...

specific Embodiment approach 2

[0030] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the weight of flax meal described in step 1: water volume ratio is 1:10-12. Others are the same as the first embodiment.

specific Embodiment approach 3

[0031] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the weight of flaxseed meal described in step 1: water volume ratio is 1:10. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a preparation method for a flaxseed cake polypeptide beverage. The method employs flaxseed cake as a raw material and includes the following steps: adding cellulase for pre-treatment to release protein constrained by cellulose, and adding protease to prepare flaxseed cake polypeptide, and carrying out composition and sterilization to prepare the flaxseed cake polypeptide beverage. The flaxseed cake polypeptide is prepared through the enzymatic method to overcome the defects that an alkali extraction and acid deposition method is intensive in reaction conditions and is liable to cause environment pollution and an organic solvent method is complex in processes and high in cost. The enzymatic method for hydrolyzing the flaxseed cake polypeptide has mild reaction conditions, short reaction time and low energy consumption, and is easy to control in hydrolysis degree. The flaxseed cake polypeptide beverage has excellent color and flavor, is rich in nutrition, is easy to prepare and is reasonable in cost. The method is suitable for amplification, develops a new approach for deep-processing of flaxseed cake protein and provides a new product for beverage industry.

Description

technical field [0001] The invention relates to a method for preparing a beverage, in particular to a method for preparing a linseed meal polypeptide beverage with linseed meal as the main raw material. Background technique [0002] Flax, also known as flax, is an annual or perennial herb of the family Linaceae. Flax meal is a by-product of flaxseed degreased by machine pressing or organic solvent method. Its protein content can reach 32-49%, mainly composed of albumin and globulin. For a long time, linseed meal has been mainly used as animal feed, fuel or returned to farmland as fertilizer, which has not been well developed and utilized, resulting in a great waste of resources. [0003] Peptides are a type of polymer formed by more than 10 amino acids through peptide bonds. Compared with proteins and completely free amino acids, polypeptides have the advantage of being easily absorbed and will not be hydrolyzed twice during absorption. In addition, peptides also have a va...
