Abstract

The invention provides a method for treating marten, racoon dog and fox carcasses with an enzymolysis process. The method comprises the following steps: performing enzymolysis on the carcasses to obtain an enzymolysis solution; performing mixed enzymolysis on houttuynia cordata thunb, radix sophorae flavescentis, radix astragali and osmanthus fragrans; mixing two enzymolysis solutions; adding calcium citrate and performing enzyme deactivation, cooling, filtration and concentration; and adding auxiliary materials and performing homogenization and spray-drying to prepare a small peptide nutritional agent. According to the method, the marten, racoon dog and fox carcasses are properly treated, so that waste resources are fully utilized, the treatment cost is reduced, and the environmental pollution is avoided; due to the addition of the traditional Chinese medicine ingredients, the nutritional value of small peptides to animals can be improved; meanwhile, the traditional Chinese medicines are applied to weaning materials of piglets, so that the dysentery of the piglets can be prevented; and calcium citrate improves the bitter taste generated after enzymolysis and facilitates the animals to absorb small peptides.

Description

technical field [0001] The invention relates to a method for enzymatically treating meat carcasses, in particular to a method for enzymatically treating mink, raccoon and fox carcasses. Background technique [0002] With the improvement of living standards, people's demand for fine fur is increasingly strong. The latitude of Shandong is very suitable for the growth of fur animals. In addition to the rich fishery resources near the sea and meat resources such as chicken racks and duck racks, fur animals such as Breeding of minks, raccoon dogs, and foxes flourished in the eastern part of the Shandong Peninsula. According to the statistics of the Shandong Provincial Animal Husbandry Bureau, in 2012, the number of minks, foxes, and raccoons raised in the province reached 75 million, of which Zhucheng (a county-level city in the eastern Shandong Peninsula) raised more than 12.5 million. The value of farmed mink, raccoon dog, fox and other fur animals is mainly in their fur, whil...
