A kind of highly soluble soybean peptide oral liquid and its preparation process

Abstract

A highly soluble soybean peptide oral liquid and a preparation process thereof relate to the field of oral liquids. The raw materials of the highly soluble soybean peptide oral liquid according to the embodiment of the present invention include: 1%-15% soybean peptide powder; 0.1%-1% acai fruit; 0.01%-0.2% taurine; 0.1% ‑2% guarana extract; 5%‑20% fructose; 10%‑30% isomalt; the balance is water, and the content of soybean peptide in highly soluble soybean peptide oral liquid is high, which has significant relief The effect of fatigue; the preparation process of high-soluble soybean peptide oral liquid is to dry mix the solid raw materials first, add some water, stir at 60-70°C for 15-40min, add the remaining amount of water, heat and degas, and adjust the pH 4.0-5.0, filtered, sterilized at 117-125°C for 10-20 minutes, and hot-filled. This process consumes less raw materials and has a simple process, which is suitable for large-scale production.

Description

technical field [0001] The invention relates to the field of oral liquids, and in particular to a highly soluble soybean peptide oral liquid and a preparation process thereof. Background technique [0002] The general process flow of common oral liquid production is: mixing materials to obtain liquid, filtering, potting, lamp inspection, sterilization and other steps. Protein oral liquid products will go through a sterilization process after filling. According to different product characteristics, the sterilization methods are different, but the sterilization temperature is above 80°C. At the same time, in order to prolong the shelf life of oral liquid products, the pH Most are acidic. Under the condition of pH 4.2-6, the solubility of soybean peptide after sterilizing at 121°C for 30 minutes directly determines its addition amount in oral liquid, but the oral liquid product with high protein content obtained by adding ordinary soybean peptide In an acidic pH environment, ...

On the other hand, the invention patent with the patent number 201010270873.6 discloses a nitrogen source enhanced oral liquid containing peptides and oligosaccharides and its preparation method. The amount of soybean peptide powder added is 20%-30%, and 0.18 um-0.22um microporous membrane for filtration, and finally sterilized at a high temperature of 135-140 ℃. The requirements are particularly high, and the consumption of raw materials is particularly large, time-consuming, and expensive. It is not suitable for large-scale production of oral liquids, and it is not clearly stated that the amount of soybean peptide powder added is 20%-30%. The oral liquid is filtered and the filtrate Whether the content of soybean peptides in medium reaches 20%-30%. In addition, microporous membranes have particularly strong interception properties and can be used for sterilization of liquid products that cannot be subjected to high temperature and high pressure. Therefore, microporous membranes may have blocking properties for soybean peptides
