Beschreibung
Zusammenfassung:	The invention provides a safe and efficient novel protein antifreeze agent as well as a preparation method and an application thereof. The preparation process of the protein antifreeze agent comprisesthe steps that fish scales are dried, pretreated, subjected to steam explosion treatment, decalcified, subjected to enzymolysis, subjected to hot water leaching and freeze-dried, and the obtained protein antifreeze agent can serve as a cryoprotectant to be applied to cryopreservation of aquatic products, enzymes and strains; the raw material is wide in source, low in cost, simple in process and efficient, the prepared novel antifreeze agent has the advantages of being safe, nutritional, wide in application range and the like, quality deterioration of frozen food and biological products can beeffectively controlled, and the freeze-thaw stability of the frozen food and biological products is enhanced. 本发明提供了一种安全高效新型蛋白抗冻剂及其制备方法和应用，所述蛋白抗冻剂的制备过程为：鱼鳞经干燥、预处理、蒸汽闪爆处理、脱钙、酶解、热水浸提及冻干后得到，所得蛋白抗冻剂可作为冷冻保护剂应用于水产品、酶及菌种的冷冻保藏；本发明原料来
