Method for preparing fermented virus-free cottonseed meal feed protein

Abstract

The present invention discloses a method for preparing fermented virus-free cottonseed meal feed protein. The invention relates to a production process which uses cottonseed meal as raw material and produces the virus-free cottonseed meal feed protein by microbial technology in a transformation way, in particular to a microbial fermenting process of using multi-strains mixed solid to ferment and prepare virus-free cottonseed meal. Fermentation cultures of one strain Saccharomyces cerevisiae which is cultured in an amplification way, one strain Candida tropicalis, one strain Bacillus subtilis and one strain Lactobacillus are evenly mixed in the proportion of 2 to 1 to 1 to 1 and are inoculated in cottonseed meal (through 40 mesh sieve) with 5 percent of the inoculation amount, wherein, the water content of the cottonseed meal is 50 percent; simultaneously, substrate culture media (5 percent of molasses, 5 percent of bran, 0.5 percent of ammonium sulfate, and the initial pH value is 6.0) are added, evenly mixed, fermented for 72hours at 30 DEG C in aerobic way, dried and sampled at 60 DEG C; finally, the nutrient analysis is carried out on the cottonseed meal before and after fermentation; when weighed and packaged, finished products of the fermented cottonseed meal can be stored for 6 months at a cool and dry place. The fermented cottonseed meal can be used as feeds for beef cattle, chicken, tilapia, etc.

Description

technical field [0001] The invention relates to a production process of using cottonseed meal as a raw material to transform and produce detoxified cottonseed meal feed protein by using microbial technology, in particular to a microbial fermentation process for preparing detoxified cottonseed meal by multi-bacteria mixed solid fermentation. Background technique [0002] In recent years, my country's animal husbandry and feed industry have developed very rapidly, and the contradiction of shortage of feed resources has become increasingly prominent. According to expert forecasts, from 2010 to 2020, the balance of protein feed in my country will be 24-48 million tons, and the balance of cakes will be 25.6 million tons. For a long time, soybean meal, the protein feed raw material that my country has mainly relied on, has become increasingly tight due to various factors such as output, climate, and domestic and foreign market price fluctuations. The price has risen and fluctuated...
