Problems solved by technology

The disadvantage of biological fermentation detoxification is that the treatment cycle is long and the cost is high
[0004] By retrieving the existing technologies at home and abroad, it is found that there is no literature report on the detoxification of cottonseed cake powder in the circulating fluidized bed by infrared radiation, and there is no Literature report on preparation of cottonseed meal protein powder by detoxification of cottonseed meal meal in circulating fluidized bed by infrared irradiation

Abstract

The invention discloses dephenolization cottonseed meal protein powder and a preparation method thereof. The method comprises the following steps: firstly, coarsely crushing cottonseed meal, and then adding cellulose and hemicellulase to carry out enzymolysis on a cellulosic material in the cottonseed meal so as to improve the palatability; arranging the cottonseed meal into a circulating fluidized bed equipped with an infrared emission device; carrying out superfine grinding and infrared irradiation on the material in a boiling state by the circulating fluidized bed; destroying the structure of free gossypol in the cottonseed meal so as to reduce the content of the free gossypol to achieve the detoxification effect; finally drying to prepare the dephenolized cottonseed meal protein powder. The dephenolized cottonseed meal protein powder can be applied to the fields of food and feeds.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a cottonseed cake protein powder irradiated to reduce phenols in a fluidized bed and a preparation method thereof. Background technique [0002] Cottonseed meal is a by-product of cottonseed oil extraction. The by-products of extracting oil from cottonseed after husking are called cottonseed cake and meal, the cake after oil extraction by pressing, and the meal after pre-press extraction or direct extraction. In cottonseed cake, crude protein content is 20-44%, crude fat is 1-7%, crude fiber is 10-20%, crude ash is 5-8%, free gossypol is 1.0-4.8%, and cottonseed protein It is close to soybean protein in quality, and its nutritional value is also higher than that of cereal protein. It has 8 essential amino acids, especially the lysine content is as high as 6%. At present, my country's annual output of cottonseed is more than 8 million tons, and the annual output of co...
