Abstract

The invention belongs to the technical field of feed additives, and in particular relates to an α-galactosidase soft capsule feed additive and a preparation method thereof. The method comprises the following steps: 1) adding α-Gal to the phosphate buffer solution, then adding β-CD, and then standing for the reaction after homogenization, until the end of the reaction, to obtain the α-Gal-β-CD additive solution; 2 ) adding B-type gelatin into water, adding glycerin, preservatives and titanium dioxide after fully swelling, mixing evenly to gelatinize, and obtaining a rubber compound; 3) filling. The soft capsule additive obtained by the present invention utilizes the inhibitory effect of the cyclodextrin inhibitor on α-Gal, so that the α-Gal enzyme activity in the animal feed undergoes a process of first low and then high, so that the α-Gal in the feed Catalyzes during more favorable periods of digestion.

Description

technical field [0001] The invention belongs to the technical field of feed additives, in particular to an alpha-galactosidase soft capsule feed additive and a preparation method thereof. Background technique [0002] α-galactosidase (α-galactosidase, α-Gal) is an exoglycosidase that catalyzes the hydrolysis of α-galactosidic bonds. It is also known as melibiose because it can decompose melibiose. - Hydrolysis of galactosidic linkages. This feature makes it useful for improving and eliminating anti-nutritional components in feed and soy-based foods. [0003] Corn-soybean meal-based feed is a good source of protein feed due to its nutritional characteristics such as high crude protein content, balanced amino acid content and rich in lysine. However, the content of Ⅱ-galactoside sugar in soybean meal and miscellaneous meal feed is relatively high, and it is an anti-nutritional factor in feed. Its anti-nutritional effect is often ignored, and it is difficult to decompose it b...
