Preparation method for fermenting high-nutrition animal feed by utilizing leftovers

Abstract

The invention provides a preparation method for fermenting a high-nutrition animal feed by utilizing leftovers, and particularly aims at solving the problem of waste of human catering food. The leftovers are converted into the high-nutrition animal feed through a modern biological integration technology, the utilization rate of the leftovers is increased, the resource waste is reduced, the environment is purified, the social cost is reduced, and the harmonious development of society is promoted. The high-nutrition animal feed prepared by a method contains a large amount of proteins, sugar, fat, amino acids, vitamins, trace elements and other nutrients, can produce a variety of organic acids and enzymes after probiotic fermentation, can supplement intestinal probiotics for animals and maintain gastrointestinal flora balance of animal bodies, and has the advantages that other common raw materials do not have. The method is wide in raw material source, easy in acquisition, low in manufacturing cost, easy to manufacture, high in operability and suitable for large-scale production, and has good economic benefits and social benefits.

Description

technical field [0001] The invention belongs to the technical field of animal feed preparation, and in particular relates to a preparation method for fermenting high-nutrition animal feed with leftovers. Background technique [0002] Food is the most important thing for the people. As a big food country, the long-standing food culture has always been the pride of the Chinese. However, in today's highly developed catering industry, the problem of food waste has become increasingly prominent. Statistics show that the per capita food waste rate in China's catering industry is 11.7%. Every day, tens of thousands of tons of food is thrown from the table. Chinese consumers waste 8 million tons of food protein and 3 million tons of fat in catering alone every year, and the leftovers that are thrown away at will, at least throw away the annual rations of about 200 million people. [0003] In 2013, a "CD Action" advocating strict economy and opposing extravagance and waste swept a...

Problems solved by technology

However, some of these methods need to occupy a large amount of land, some have high processing costs, some have low resource utilization rates, and secondary pollution is common.

At present, although there are also patents on the use of kitchen waste to make animal feed, the general process of feed production in these patents is dehydration of kitchen waste, inoculation of high-temperature-resistant yeast for fermentation, drying, and crushing; there is pollution from the accumulation, collection, and transportation of kitchen waste The problem is that the operability is not strong in actual processing, and the fermentation strain is single, the raw material fermentation is not complete, and the resource utilization rate is low
