Protein hydrolysate as well as preparation and application thereof

The invention provides a proteolysis product as well as preparation and application thereof. A preparation method of the proteolysis product comprises the following steps: crushing animals and plants, adding water, and sequentially carrying out high-pressure treatment, enzymolysis and low-temperature plasma treatment, so as to obtain the proteolysis product. Wherein the pressure of the high-pressure treatment is 100 to 400 MPa. According to the method disclosed by the invention, through high-pressure and low-temperature plasma treatment, the obtained protein zymolyte can remarkably improve the salty taste of the seasoning (the protein zymolyte with the protein content of 20mg/mL can increase the salty taste intensity of a 50mmol/L NaCl solution by 45.6%-57.2%), and the protein zymolyte can be used as a high-quality salty taste enhancer and is beneficial to guaranteeing the diet health of consumers. 本发明提供了一种蛋白酶解物及其制备和应用。所述蛋白酶解物的制备方法为：将动植物粉碎、加水后，依次进行高压处理、酶解、低温等离子体处理即得；其中，所述高压处理的压力为100～400MPa。本发明通过高压协同低温等离子体处理，得
