Preparation method of alfalfa leaf protein peptide beverage

Abstract

The invention discloses a preparation method of an alfalfa leaf protein peptide beverage. The method includes adopting fresh bloom alfalfa leaves as raw materials, obtaining alfalfa liquid by the washing, shearing, beating and filtering process, extracting alfalfa leaf protein by the acid-heating method, preparing alfalfa leaf protein peptide powder by enzymolysis of the alfalfa leaf protein, and obtaining the alfalfa leaf protein peptide beverage by mixing the peptide powder, concentrated fruit juice, castor sugar, sour agent, beta-cyclodextrin, compound stabilizer, emulsifier and drinking water. The beverage includes, by weights: 5 to 10 parts of alfalfa leaf protein peptide powder, 10 to 20 parts of concentrated fruit juice, 5 to 10 parts of castor sugar, 1 to 5 parts of sour agent, 0.2 to 0.5 part of beta-cyclodextrin, 0.1 to 0.5 part of compound stabilizer, 0.05 to 0.1 part of emulsifier and the balance of drinking water. According to the method, easily-absorbed alfalfa leaf protein with the low molecular weight is adopted as the protein source, the concentrated fruit juice and other food additives are added, various nutrients of proteins and carbohydrates are provided, and various biologically active ingredients with the health caring functions are provided. Thus, the beverage has good taste and flavor, nutrients are rich, various physiological functions of anti-aging performance, body immunity enhance and digestion and absorption promotion are provided, and the beverage is adaptive to various people. The process is simple, the conditions are mild, energy consumption is low, the production period is short, the peptide preparation rate is high, the operationality is high, and the method is adaptive to large-scale industrial production.

Description

technical field [0001] The invention relates to a functional beverage, in particular to a preparation method of an alfalfa leaf protein peptide beverage. Specifically, the invention relates to a method for producing alfalfa leaf protein peptide beverage by adopting an enzymatic hydrolysis method, and belongs to the field of food. Background technique [0002] Alfalfa leaf protein peptide is a polymer of several, dozens or even hundreds of amino acids linked by peptide bonds, which is produced after hydrolysis of alfalfa leaf protein by protease. In recent years, many scholars have studied the digestion and absorption mechanism of peptides. They believe that peptides are more easily absorbed by the intestine than proteins and free amino acids. Biological metabolism experiments have confirmed that the absorption rate of peptides is greater than that of free amino acids, and it is easier and faster than amino acids to pass through. Small intestinal mucosa to be absorbed and u...
