Problems solved by technology

[0004] (1) Production of fermentation series products: B starch can be used as raw material for fermentation to produce monosodium glutamate, alcohol, citric acid, microbial culture medium, etc., but because there is a certain amount of non-starch components in B starch, it makes fermentation difficult to control and post-processing difficult
[0005] (2) Production of hydrolyzed products: Amylase can be used to degrade B starch to a certain extent to produce hydrolyzed products, such as high maltose syrup, dextrin and other products, but due to the high viscosity of B starch, it is difficult to dehydrate and filter, so that Increased process investment and reduced production efficiency
However, this requires the B starch to be completely dehydrated and ultrafinely pulverized, which increases the cost virtually, and the color of the produced superfine starch is darker, which has a certain impact on its application.
[0007] (4) Feed farmers directly as feed to pigs: the problem of this way out is that the B starch slurry is not easy to store and easy to stratify; the second is that the feed palatability is not good and the feeding effect is poor

Embodiment 1

[0017] Embodiment 1: the property comparison of enzymolysis and non-enzymolysis wheat B starch slurry

[0018] The solid content is 11Be ° wheat B starch slurry with high temperature resistant α-amylase at a pH value of 6.5, 95 ° C, with the addition of high temperature resistant α-amylase and reaction time to control the DE value of 11, 16, The hydrolyzate of 23, the hydrolyzate with different DE values ​​showed different sedimentation volumes, such as figure 1 shown. The sedimentation volume of the hydrolyzate with a DE value of 11 after homogenization under different pressures is shown in Table 1. From figure 1 It can be seen from Table 1 that the product obtained after the hydrolyzate with a DE value of 11 is homogenized under a pressure of 30-50 MPa does not settle within 1 month and has good stability.

Abstract

A process for preparing a component of liquid forage from the wheat starch slurry B by enzymolyzing includes such step as heating, enzymolyzing with refractory alpha-amylase until its DE value is 5-16, regulating pH, deactivating enzyme and homogenizing under 30-50 MPa.

Description

technical field [0001] The invention discloses a method for preparing liquid feed components by enzymatic hydrolysis of wheat B starch slurry, which belongs to the technical field of comprehensive utilization of wheat B starch slurry. Background technique [0002] There are two types of starch granules with large differences in particle size and shape in mature wheat grains, one of which is spherical in diameter and loosely distributed, and is called wheat A starch (hereinafter referred to as A starch). It is also called fine starch in the world; there is also a kind of particle diameter below 10 μm, most of which are approximately egg-shaped, and the particles are tightly packed, which is called wheat B starch (hereinafter referred to as B starch). It is also called tail starch, sludge starch or starch in industry. Squeegee starch. Wheat B starch is mainly composed of small starch granules, damaged starch granules, gluten fragments and other substances. It is one of the im...
