Problems solved by technology

[0008] 3. The reaction conditions are harsh, and the enzyme is easily inactivated, resulting in the inability to enzymatically hydrolyze
[0009] 4. It cannot promote the dissolution of mineral elements in raw materials
[0012] 2. The reaction conditions are harsh, and changes in conditions will inhibit the growth of microorganisms, making the reaction slow or unable to respond
[0013] 3. The reaction time is long, which is not conducive to control

[0032] The preparation of example 1 calcium-supplementing bamboo shoot protein hydrolyzate

[0033] 1. The pretreatment of bamboo shoots: get bamboo shoots (fresh shoots are shelled), sliced, dried under reduced pressure at 60°C to water content below 7%, pulverized, crossed a 40 mesh sieve, and set aside.

[0034] 2. Acid hydrolysis: Weigh 10 kg of bamboo shoot dry powder, put it into a reaction tank, add 40 L of 3 mol / L lactic acid solution, keep it warm at 110° C. for 15 hours, and filter.

[0035] 3. Adjust the pH value: Take an appropriate amount of calcium carbonate powder, add it to the hydrolyzate, and stir while adding it until no bubbles are generated, and when the pH value is 4, no longer add calcium carbonate powder, leave it for 30 minutes, filter, and concentrate to Specify the volume.

[0036] 4. Blending: Take the concentrated solution, add appropriate amount of additives, fill it, and sterilize it.

Abstract

The invention discloses a method for hydrolyzing bamboo shoot protein by adopting organic acid. The method comprises the following steps of: (1) preprocessing bamboo shoot; (2) adding the organic acid to hydrolyze; and (3) adding pH regulator to regulate pH value, filtering, and concentrating. By adopting the method disclosed by the invention, salt obtained by reaction between acid used for hydrolysis and the pH regulator can be removed, and dietary supplement can be existed in reaction liquid. Compared with other hydrolysis methods, the method disclosed by the invention has the characteristics of simple and convenient process, less environmental pollution and full nutrients in hydrolysate.

Description

technical field [0001] The invention relates to a method for hydrolyzing bamboo shoot protein, in particular to a treatment method for hydrolyzing bamboo shoot protein and hydrolyzate with organic acid. Background technique [0002] Bamboo shoots have been regarded as "treasures in dishes" in our country since ancient times. In terms of nutrition, many people used to think that although bamboo shoots taste delicious, they are not nutritious. . In fact, bamboo shoots are rich in nutrients such as protein and dietary fiber, and are a healthy food with high protein, high fiber and low fat. How to make full use of rich protein becomes the key to develop bamboo shoot products. [0003] A protein is a polymer compound formed by combining α-amino acids in a certain order to form a polypeptide chain, and then combining one or more polypeptide chains in a specific way. The ingested protein is digested, hydrolyzed into amino acids and absorbed in the body, and the protein needed by...
