Problems solved by technology

However, electrodialysis is an ion diffusion process from high concentration to low concentration. Therefore, when the concentration of the fresh water chamber is too high during electrodialysis, it is easy to affect the effect of desalination and even lead to the loss of protein peptides.

Abstract

The invention belongs to the technical field of peanut peptides, and particularly relates to a peanut peptide-containing composition and a preparation method and application thereof. Each 100ml of the peanut peptide-containing composition according to the invention comprises the following raw materials: 5-10g of peanut peptide, 3-8g of guava juice, 3-8g of apple juice, 3-8g of pear juice, 0.05-0.1g of citric acid, 1-7.5 g of stachyose, 0.1-1.5g of sucralose, 0.2-0.5g of maltodextrin, 0.2-0.5 g of pectin and the balance purified water. The peanut peptide-containing composition has the advantages of consistent color, no precipitates, no bitter taste, delicate taste, moderate sour and sweet taste, rich peanut peptide and fruit fragrance, and rich nutrition.

Description

technical field [0001] The invention belongs to the technical field of peanut peptides, and in particular relates to a composition containing peanut peptides and a preparation method and application thereof. Background technique [0002] Peanuts, also known as groundnuts, have been known as long-lived fruits in history. Existing studies have shown that peanut peptides obtained from peanuts have functional activities such as anti-oxidation, preventing high blood pressure, promoting growth, enhancing immunity and preventing allergies. [0003] Based on the various activities of peanut peptides, more and more new functional foods containing peanut peptides have emerged as the times require. Disclosed as Chinese patent CN101455430A is a kind of peanut peptide lactic acid bacteria beverage and its preparation method, is to soak the roasted peanut kernels, add water to grind, and then grind twice under the pressure of 40MPa; then the slurry after grinding is heated and boiled, An...
