Aquatic products contains rich nutrition,and are easy to deteriorate at room temperature.At present, the aquatic products are usually stored by low-temperature freezing storage.In the freezing process,the proteins in the aquatic products may denature to influence the product quality.For example,the gel strength and the water retention ability of surimi products decreases as the freezing time prolongs.The particle described the freeze denaturation mechanism of aquatic products,and the anti-freezing effects o...
