Embodiment 1

[0023] The crushed rapeseed cake was sterilized under high temperature and high pressure, and treated at 105°C for 10 minutes. Bacillus subtilis B 3 Insert the inoculation amount of 5% (w / w) on the rapeseed meal solid-state fermentation medium (rapeseed meal 60% (w / w), water content 40% (w / w)), and stand at 35°C Fermentation 72h. The fermented base material was dried at 50°C to obtain a protein feed product, and the content of various anti-nutritional factors and nutritional components of the product was measured at the same time. The results are shown in Table 2.

Embodiment 2

[0025] The crushed rapeseed cake was sterilized under high temperature and high pressure, and treated at 105°C for 10 minutes. Bacillus subtilis B 3 , Bacillus natto N 1 and Saccharomyces cerevisiae R 1 With an inoculation ratio of 1:1:1 by weight, a total inoculum of 5% (w / w) was inserted into the rapeseed meal solid-state fermentation medium (60% (w / w) of rapeseed meal, 40% water content (w / w)) and leave to ferment at 35°C for 72h. The fermented base material was dried at 50°C to obtain a protein feed product, and the contents of various anti-nutritional factors and nutritional components of the product were measured at the same time, and the results are shown in Table 2.

Embodiment 3

[0027] The crushed rapeseed cake was sterilized under high temperature and high pressure, and treated at 105°C for 10 minutes. Bacillus licheniformis D 2 , Bacillus natto N 1 and Pichia P 2 With an inoculation ratio of 1:1:1 by weight, a total inoculum of 5% (w / w) was inserted into the rapeseed meal solid-state fermentation medium (60% (w / w) of rapeseed meal, 40% water content (w / w)) and leave to ferment at 35°C for 72h. The fermented base material was dried at 50°C to obtain a protein feed product, and the contents of various anti-nutritional factors and nutritional components of the product were measured at the same time, and the results are shown in Table 2.

Abstract

The invention relates to a preparation method of protein feed in oilseed dregs. Oilseed dregs are used as a main material in which accessories are added and mixed, and the mixed material is preprocessed and mixed with water; seed liquid resurrection is carried out on the sieved strain of high-efficient degradation anti-nutritional factors; in the form of single strain or combination, 2% to 15% of general inoculum concentration of the strains by weight are simultaneously connected with mixture solid fermentation medium after preprocessing on standing at the temperature of 25 to 45 DEG C, mixed and fermented for 24 to 96 hours; after fermentation, the finished products are obtained after drying and dehydration; the raw materials have the following proportions by weight: 40% to 60% of oilseed dregs, 0 to 10% of accessories and 40% to 50% of water. According to the composition, characteristics and nutrient advantages of anti-nutrient substance in oilseed dregs, the method not only can efficiently eliminate anti- nutritional factors in the dregs but also can improve the oligopeptide content and simultaneously maintains higher protein content so that the quality of protein feed can be further advanced and improved.

Description

technical field [0001] The invention relates to a preparation method of oil cake protein feed, which is used for improving the utilization rate of oil cake as feed. Background technique [0002] Plant protein feed is the most widely used and most important type of protein feed, including oil cakes, leguminous seeds and by-products of the starch industry. Among them, oilseed cake has higher protein content and more balanced nutritional components, and is an excellent natural vegetable protein resource. However, due to the existence of anti-nutrient components, the wide application of oilseed cake in feed is limited, as shown in Table 1. [0003] Table 1 Anti-nutritional factors in oilseed protein cake [0004] [0005] Oilseed cakes include soybean cakes, cottonseed cakes, rapeseed cakes, peanut cakes, sunflower cakes, flax cakes, sesame cakes, etc. The output of other oilseed cakes (collectively referred to as miscellaneous cakes) except soybean cakes in my country can...
