Abstract

The invention relates to a biological detoxification method for camellia seed cakes. According to the invention, dipotassium hydrogen phosphate, magnesium chloride, 2000-4000U / g of acidic cellulase, microbe strains, and the like are added to crushed camellia seed cake; the mixture is well mixed by stirring, and is subject to a reaction for 10-15 days under a temperature of 40-50 DEG C under the effects of both the microbes and the acidic cellulase; an obtained material is dried by baking, and is crushed, such that a finished product is obtained. Tea saponin content in the obtained product is lower than a safety index of a feedstuff standard, and the nutritive value of the product is higher than non-fermented camellia seed cakes. Protein content of the product reaches 15-20%, which is improved by more than 5%. Free amino acid content of the product is higher than 5%, which is improved by more than 25%. Reducing sugar content in the product is higher than 5%, saponin content in the product is lower than 1.0%, and a detoxification rate of the product is higher than 90%. The product can be directly used as a feedstuff, such that a problem of camellia seed cake intoxication in prior art is solved. The production method is advantaged in simple technology and good effect. With the method, non-toxic camellia seed cakes satisfying the requirements of the feedstuff standard can be provided.

Description

technical field [0001] The invention relates to a biological detoxification method combining microorganisms and enzymes of tea seed cakes. Background technique [0002] Camellia oleifera is an important oil crop in the hilly areas of southern my country, accounting for more than 80% of the national woody edible oil crops. Tea seed cake, also known as tea meal, alias tea bran, tea dry, tea seed cake. The purple-brown particles are the residue left after the wild camellia oil fruit is pressed. Tea seed cakes after oil extraction also contain a large amount of starch, protein, crude fat, soluble sugar and tea saponin, etc., which can be re-extracted and utilized. The area of ​​Camellia oleifera forests in my country is about 4 million hectares, and it is the country with the most varieties, the widest distribution and the largest output of Camellia oleifera in the world. According to statistics, the area of ​​tea plantations in my country is about 1 million hectares. In rece...
