Problems solved by technology

Wastes of animal origin are discarded without being used, which causes environmental pollution on the one hand and waste of resources on the other hand
[0004] At present, there are few research reports on the recycling of animal-derived wastes, and there is an urgent need for a processing method for animal-derived wastes to make full use of these resources

Abstract

The invention belongs to the technical field of animal processing, and discloses an animal-derived waste processing product, and a preparation method and an application thereof. The preparation method of the animal-derived waste processing product comprises the following steps: obtaining animal-derived wastes comprising animal internal organs; carrying out primary mixing on the animal-derived wastes, pancreatin and nuclease to obtain a first product; and carrying out secondary mixing on the first product and water, carrying out enzymatic hydrolysis at 38-45DEG C under a pH value of 7.2-8.0, deactivating, filtering, and collecting the obtained filtrate. The preparation method of the animal-derived waste processing product has the advantages of simple process, and full recycling of the animal-derived wastes, and the animal-derived waste processing product contains a large amount of organic nitrogen element, and can be used to prepare fertilizers.

Description

technical field [0001] The invention belongs to the technical field of animal processing, and in particular relates to animal source waste processed products, a preparation method and application thereof. Background technique [0002] Animal breeding includes livestock and poultry breeding, aquaculture and special economic animal breeding. Livestock and poultry farming is mainly the breeding of cattle, horses, donkeys, pigs, sheep, rabbits, chickens, ducks, geese and other livestock and poultry, providing people with rich food such as meat, milk, eggs and poultry. Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. For animals, the main breeding objects of aquaculture include fish, shrimp, abalone, scallops, sea cucumbers, etc., providing people with delicious food such as fish, shrimp, crab, and shellfish. Special economic animal breeding is the artificial large-scale breeding of special economic a...
