Method for detoxicating rapeseed cakes or rapeseed dregs

Abstract

The invention discloses a method for detoxicating rapeseed cakes or rapeseed dregs.In the method, the rapeseed cakes or rapeseed dregs containing glucosinolate are ground and detoxicated in a high energy grinder under the action of grinding aid. The method comprises the following steps: 1) weighing rapeseed cakes or rapeseed dregs containing glucosinolate and then weighing grinding aid with a weight being 1-10% of the weight of the rapeseed cakes or rapeseed dregs and then evenly mixing the materials; 2) adding the mixture into the high energy grinder and grinding the mixture for 50-60min to obtain the detoxicated rapeseed cakes or rapeseed dregs.The method of the invention overcomes the weaknesses of the traditional detoxication method such as high cost, complicated processing equipment, long processing cycle, large labor intensity, large energy consumption and low detoxication rate; in addition, the detoxication method features simple process, small equipment investment, convenient operation, high detoxication efficiency, no generation of three wastes in the process of detoxication and adaptability to large-scale industrialized application; moreover the detoxicated rapeseed cakes and rapeseed dregs features good palatability, high digestibility and low content of anti-nutritional factors.

Description

technical field [0001] The invention relates to the field of protein resource development for feed, in particular to a method for detoxifying rapeseed cake or rapeseed 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. Rapeseed cake (meal) contains 35% to 45% vegetable protein, which is an important vegetable protein resource. Moreover, the amino acid composition in the protein is relatively balanced, and its feeding value can be compared with soybean cake. [0003] But rapeseed cake (meal) contains glucosinolates, th...

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
