Embodiment approach

[0018] First of all, select soybeans, that is, select fresh, bright color, uniform and intact particles, less impurities, and no mold spots. At the same time, soybeans should be screened and cleaned by dry cleaning. Vibration screening and vacuum transportation are used for separation and cleaning. . Then dry it by dry method until the water content is 8%, then it can be crushed and peeled, so that the husk content of the crushed soybeans is less than 8%, and finally crushed and classified by a hammer mill, so that the product particles can be kept at 0.2mm-0.5mm , The requirement of this process is not to use strong heat treatment, the drying temperature should not exceed 80 ℃, avoid direct steam heating so as to ensure the solubility of the product, and the protein retention rate is above 95%.

[0019] The degreasing method is degreasing by extracting meal with low denaturation. The protein denaturation degree of the extracting meal obtained by this method is low, and high-q...

Abstract

The invention discloses a production method of high-purity instant protein powder, which comprises the following steps: refining and separating the low-denatured leached defatted soybean meal, centrifuging and concentrating, and is characterized in that it also includes the following steps: after refining and separating Perform high-purity membrane separation, followed by ultra-pure extraction; after centrifugation or preparation; or after centrifugation, concentration; after concentration process, drying, drying and spraying to make granules. Since the present invention adopts the ultra-pure extraction technology and the whole process of low-temperature process, the high-purity instant protein powder with hollow crystalline particles is made, so that the protein does not denature, maintains high activity, has a pleasant aroma, and is more beneficial to human health.

Description

Technical field: [0001] The invention relates to a preparation method of high-purity instant protein powder. Background technique: [0002] At present, the production method of separating protein is mainly alkali-soluble acid precipitation method. Now the production of protein powder must use acid, alkali and high temperature processes, resulting in a small amount of acid and alkali residues, making non-protein components, ash, salt, heavy metals, There are many harmful factors, etc., which directly affect the purity of the protein, and more importantly, constitute a hazard to human health, and have strong fishy smell, poor taste, and are not easy to dissolve when eating. The protein is denatured by high temperature, destroying the protein Nutrients and nutritional value, so that the human body is not easy to absorb. And waste water pollutes the environment. The supercritical carbon dioxide extraction process is a mature process, which is widely used in other fine chemical...
