Example Embodiment

[0024] The purpose of the present invention can be achieved as long as the cake for feed of the present invention has the above-mentioned composition. The present invention has no special requirements for its preparation method. In order to further increase the protein content in the cake for feed, a method for increasing the protein content of the cake for feed is preferred. Include the following steps:

[0025] (1) steam-exploding the cake raw material to obtain slurry A;

[0026] (2) enzymatic hydrolysis is carried out to slurry A;

[0027] (3) The slurry obtained by enzymatic hydrolysis is sequentially separated and dried.

[0028] In the present invention, the cake meal raw material can be any meal meal material that is interconnected by dietary fiber, phytic acid and protein, preferably one or more selected from rapeseed meal, rice bran meal and cottonseed meal.

Example Embodiment

[0029] According to a preferred embodiment of the present invention, the particle size of the cake raw material is not greater than 0.38mm, preferably not greater than 0.25mm. By adopting this preferred method, the feed cake with high protein content, low phytic acid content and good palatability can be obtained.

[0030] In the present invention, preferably, the cake produced during the processing of oilseed crops can be processed by the pulverization method and the grinding method, so as to obtain the cake raw material of the above-mentioned particle size.

[0031] In the present invention, the particle size of the cake raw material is measured by ordinary sieving.

[0032] According to the present invention, preferably, the embodiment of the steam explosion includes cooking a mixture containing the cake raw material and water in a steam explosion device.

[0033] According to the present invention, preferably, the cooking temperature is 120-200°C, preferably 160-180°C.

Example Embodiment

[0069] Example 1

[0070] Take 50g of rapeseed meal with a particle size of not more than 0.25mm and mix it with water in a steam explosion device at a mass ratio of 1:2 for cooking. The cooking temperature is 160°C and the cooking time is 10min. Obtain slurry A, after slurry A is cooled to room temperature, add water to adjust the material-liquid mass ratio to 1:4, add 6moL / L sodium hydroxide solution to adjust pH to 5.2, and add 2500U per gram of dry matter at 40°C. Phytase, enzymatic hydrolysis for 2 hours to obtain slurry B. Add 6 moL / L hydrochloric acid to adjust the pH of slurry B to 3.3, add complex polysaccharase relative to 15FBG per gram of dry matter at 42°C, and enzymatically hydrolyze for 24h to obtain slurry C. The pH of the slurry C was adjusted to 4.3, centrifuged at 3000 g for 10 min, and then placed in a drum for drying at a drying temperature of 60° C. and a drying time of 4 h.

Abstract

The invention relates to the field of feed, and particularly provides a high-protein feed cake meal, a method for increasing the protein content of a feed cake meal and the feed cake meal obtained with the method. The method includes the steps that (1) raw materials of the cake meal are subjected to steam explosion, and slurry liquid A is obtained; (2) the slurry liquid A is subjected to enzyme hydrolysis; (3) the slurry liquid after being subjected to enzyme hydrolysis is sequentially separated and dried. By means of the method, the feed cake meal which is high in protein, low in phytic acid and good in palatability can be prepared, and effective using of the cake meal in feed industries.

Description

technical field [0001] The invention relates to the technical field of feed processing, in particular to a high-protein cake for feed, a method for increasing the protein content of the cake for feed, and a cake for feed prepared by the method. Background technique [0002] my country is a big country in the processing of oil crops. In 2014, the output of oil crops reached 42.72 million tons, and most of the oil crops were used for processing and producing oils. In the process of oil processing, oil crops will produce a large amount of cakes, such as rapeseed meal, rice bran meal and cottonseed meal. The crude protein content of these cakes is generally 35-42%, and the amino acid composition is relatively balanced. Excellent protein resources, widely used in the feeding of pigs, cattle, fish and other animals. [0003] In recent years, the research on oil crops in my country has developed very rapidly and achieved obvious results, but the research mainly focuses on the chem...
