Abstract
A compound and a method for prolonging shelf life of frozen aquatic products are provided. The compound includes: 15-20 parts by weight of modified carboxymethyl chitosan, 5-12 parts by weight of pectin, 2-5 parts by weight of oleic acid, 1-3 parts by weight of yeast selenium, 1-3 parts by weight of natamycin and 2-6 parts by weight of nisin. The method includes sequentially treating a frozen aquatic product under a mixed gas and soaking the frozen aquatic product in the compound. The method can obviously slow down the degradation and oxidative denaturation of protein in aquatic products during cold storage, thus effectively maintaining the activity of protein in the aquatic products and slowing down the deterioration of the aquatic products.
