Problems solved by technology

[0003] At present, the industrial process for preparing plant-derived compound amino acid products is generally to hydrolyze plant-source protein meal with concentrated hydrochloric acid, then add alkali to neutralize it, and then adjust it into a product with neutral pH or weak acidity. This method has the advantages of thorough hydrolysis, cost-effectiveness and high efficiency. There are also unavoidable shortcomings, such as: there are many impurities in the product, carbohydrates will produce bitter taste after high-temperature hydrolysis, which will affect the taste; fat will generate a large amount of 3-chloropropanol after high-temperature reaction, high-dose 3-chloropropanol has physiological Toxicity, can cause tumors, cause damage to the kidney and reproductive system; the product contains many impurities, low amino acid content, and the umami taste is not outstanding; the product contains high salt content, which does not conform to the concept of healthy life, and its usage is limited, thus affecting its addition effect Wait
[0004] Therefore, there is an urgent need in the art for a method for preparing a high-purity, low-salt, delicious plant-derived compound amino acid product to solve the problems of high salt content, many impurities, and low safety in the plant-derived compound amino acid product

Abstract

The invention discloses a preparation method and application of high-quality food-grade plant-derived compound amino acid. The preparation method comprises the following steps: pretreating vegetable proteins, followed by impurity-removing and purifying; mixing the pretreated vegetable proteins with hydrochloric acid and carrying out acid hydrolysis; removing the hydrochloric acid (80% or above) from hydrolysate liquid by a hydrogen chloride recovery device to realize cyclic utilization of the hydrochloric acid; decolorizing acid-removed liquid to obtain decolorized liquid, and removing anionsand cations by using anion-exchange resins and cation-exchange resins; and subjecting effluent liquid to concentrating and spray drying to obtain the high-quality food-grade plant-derived compound amino acid. The invention has the advantages of simple preparation process, low energy consumption, low product salt content, short production cycle and high product quality. Compared with the traditional acid-hydrolyzed vegetable protein products, the salt content and the chloropropanol content of the high-quality food-grade plant-derived compound amino acid are greatly reduced, and the high-qualityfood-grade plant-derived compound amino acid is in line with the development trend of low-salt health food.
