Detoxification method of cottonseed cake or cotton seed meal

Abstract

The invention discloses a detoxification method of cottonseed cake or cotton seed meal, which is a method for grinding and detoxifying the cottonseed cake or the cotton seed meal containing free gossypol in a high-energy grinder under the effect of the grinding auxiliary agent, and comprises the following steps that: 1) the cottonseed cake or the cotton seed meal containing the free gossypol is measured, and then the grinding auxiliary agent with the weight being 1 to 10 percent of that of the cottonseed cake or the cotton seed meal is measured to be uniformly mixed with the cottonseed cake or the cotton seed meal; 2) the above mixture is added into the high-energy grinder to be ground for 5 to 60 minutes so as to obtain the detoxified cottonseed cake or the detoxified cotton seed meal. The method overcomes the weaknesses of the traditional physical and chemical detoxification technology that the high temperature and high-moisture treatment is required, and the energy consumption is high, has simple process, less equipment investment, convenient operation, high detoxification efficiency, is free from three wastes during the production process, and is applicable to the large-scale industry. The prepared detoxified cottonseed cake or the detoxified cotton seed meal has good palatability, high digestibility and low content of anti-nutrition factor.

Description

technical field [0001] The invention relates to the field of protein resource development for feed, in particular to a method for detoxifying cottonseed cake or cottonseed meal. Background technique [0002] With the rapid development of my country's feed industry, the contradiction of serious shortage of protein feed resources has become increasingly prominent, which has become the main restrictive factor for the development of my country's feed industry, and will become the bottleneck of the development of my country's animal husbandry for a long time. The development and utilization of protein resources has become my country's development of feed important issues for industry. As an important by-product of cotton crops, cottonseed cake (meal) contains 30% to 45% crude protein (CP), and is an important protein feed resource. Its output is second only to soybean meal in my country's cake feed resources. [0003] However, cottonseed cake (meal) contains 0.6-2.5% gossypol, wh...

Problems solved by technology

However, the detoxification rate of the current chemical method is not high, and the effect of the additive detoxification method is inaccurate; the physical method will lose some nutrients, the investment in equipment is large, the process is complicated, and the operating conditions are harsh, so it is not suitable for large-scale industrial applications; and microbial fermentation The effect of the method and the detoxification mechanism need to be further studied
