The application discloses a kind of low denaturation low
phytic acid plant protein and its preparation method and application.The method comprises the following steps: first, extract liquid is mixed with material, and after sufficient extraction, insoluble matter is removed by
centrifugal separation and supernatant is collected.Then, membrane
separation system is used to purify and concentrate
protein.Subsequently, non-thermal sterilization treatment is carried out by hydrodynamic
cavitation equipment,
spray drying, so that low denaturation, low
phytic acid soy protein product is obtained.The method has the advantages that the obtained product has high
clarity and stability, and the
solubility can reach 60% to 95% within a wide range of pH values.Furthermore, the
protein has high purity, low beany
flavor, and the
phytic acid content is 0.3% to 0.7%.Compared with
soy protein isolate prepared by heat sterilization treatment, the protein prepared by the application has lower denaturation degree, and can be applied to acidic
food systems such as sports drinks and fruit juices, special medical use formula food, protein supplements and other easily digestible foods.
