Detailed Description
In order to better understand the technical solutions, the technical solutions will be described in detail below with reference to specific embodiments, and it is obvious that the described embodiments are only a part of embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
A method for reducing the crude fiber content of whole wheat flour for feed comprises the following steps:
s1, cleaning the wheat and making the cleaned wheat into powder, and screening the bran from the powder; the bran which is separately screened out can reduce the use of an enzyme preparation and the enzymolysis reaction time, thereby improving the production efficiency; in addition, if the whole wheat flour is directly subjected to enzymolysis, nutrition loss of part of powder of wheat endosperm can be caused during fermentation, waste is avoided due to the fact that bran is screened out independently, and production cost is reduced.
S2, wetting the bran with water to enable the water content of the bran to reach 60% -65%, and adding an enzyme preparation and a leavening agent, wherein the ratio of the enzyme preparation to the bran is 1: 2000; the enzyme preparation comprises cellulase and hemicellulase, and the leaven is anaerobic bacteria such as Bacillus bifidus and lactobacillus. The leaven can assist the enzyme to decompose the crude fiber on one hand, and the fermentation reaction can bring about the rise of temperature and the reduction of PH value simultaneously, promotes the efficiency of enzymolysis reaction, if necessary, still can increase auxiliary materials such as cane sugar to increase fermentation speed.
S3, uniformly stirring the bran processed by the S2, and placing the bran into a sealed enzymolysis tank for enzymolysis, wherein the temperature in the enzymolysis tank is kept between 40 and 60 ℃, the pH value in the enzymolysis tank is adjusted to be between 4 and 4.8, and the enzymolysis time is about 24 to 72 hours.
S4, drying the bran processed by the S3, and mixing the dried bran with powder of the S1 without the bran to obtain the whole wheat flour with low crude fiber content, wherein the drying temperature is not more than 80 ℃ so as not to cause enzyme inactivation in the bran.
The detection of the cellulose content of the bran before and after enzymolysis shows that the cellulose content of the bran before the enzymolysis is 22.92g/100mg, and the cellulose content of the bran after the enzymolysis is 9.06g/100mg, which only accounts for 39.53% of the original bran content, thereby greatly reducing the content of crude fiber in the bran.
The technical scheme in the embodiment of the application at least has the following technical effects or advantages:
the crude fiber is softened and decomposed into disaccharide and glucose by an enzymatic hydrolysis method, so that the problems that the addition proportion of the conventional whole wheat flour is limited when the conventional whole wheat flour is used as a feed formula due to the excessively high content of the crude fiber, the speed of the feed passing through the stomach and the intestine is increased, the absorption and utilization rate of nutrients in the feed is influenced, and the conversion rate of the feed is reduced are solved, the content of the crude fiber in the whole wheat flour is reduced, and the proportion of the whole wheat flour in the feed formula is widened; meanwhile, the residual enzyme preparation after reaction can also have a synergistic effect with digestive enzymes in the stomach and intestines, so that the absorption of nutrients in the feed is improved, and the conversion rate of the feed is improved.
