A kind of preparation method of alfalfa leaf protein peptide drink

Abstract

The invention discloses a preparation method of an alfalfa leaf protein peptide beverage. The method includes: using fresh alfalfa leaves as raw materials, obtaining alfalfa juice through processes such as washing, cutting, beating, and filtering; extracting alfalfa leaf protein by acid-heating method; preparing alfalfa leaf protein peptide powder by enzymatically hydrolyzing alfalfa leaf protein; The peptide powder is mixed with concentrated apple juice, white sugar, citric acid, β-cyclodextrin, compound stabilizer, drinking water, etc. to obtain the alfalfa leaf protein peptide beverage. The beverage is calculated in parts by mass, including 5-10 parts of alfalfa leaf protein peptide powder, 10-20 parts of concentrated fruit juice, 5-10 parts of white sugar, 1-5 parts of sour agent, 0.2-0.5 parts of β-cyclodextrin, compound 0.1-0.5 part of stabilizer, 0.05-0.1 part of sucrose fatty acid ester, and the balance is drinking water. The preparation method of the beverage provided by the present invention uses low-molecular-weight, easily absorbed alfalfa leaf protein peptide as the protein source, supplemented with concentrated fruit juice and other food additives, not only contains various nutrients such as protein and sugar, but also contains A variety of bioactive ingredients with health functions. Therefore, the alfalfa leaf protein peptide beverage provided by the present invention has excellent taste and flavor, is rich in nutrition, and has multiple physiological functions such as anti-aging, enhancing body immunity, and promoting digestion and absorption, and is suitable for drinking by various groups of people. The invention has simple process, mild conditions, low energy consumption, short production cycle, high peptide yield and strong operability, and is suitable for 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 ut...
