Embodiment 1

[0018] 1) Add 10wt% α-Gal of the phosphate buffer solution to the phosphate buffer solution, then add β-CD until the concentration of β-CD reaches 10mmol / L, then leave it to react after homogenization, and the reaction time is 90min, the reaction temperature is 35°C, the pH value at the end of the reaction is 6.5, and the α-Gal—β-CD additive solution is obtained;

[0019] 2) Dissolve 100 parts of B-type gelatin in 90 parts of water, fully swell, add 30 parts of glycerin, 1.5 parts of preservative and 1.5 parts of titanium dioxide, mix evenly for gelation, the gelation temperature is 75 ° C, and then Evaporate 90% of the water at 85°C to obtain the rubber compound;

[0020] 3) Use the α-Gal-β-CD additive liquid obtained in step 1) as the soft capsule additive liquid, and use the rubber material obtained in step 2) as the soft capsule rubber material for filling to obtain α-galactosidase soft capsule feed additive.

Embodiment 2

[0022] 1) Add 12wt% α-Gal of the phosphate buffer solution to the phosphate buffer solution, then add β-CD until the concentration of β-CD reaches 10mmol / L, then leave it to react after homogenization, and the reaction time is 120min, the reaction temperature is 32°C, the pH value at the end of the reaction is 7, and the α-Gal—β-CD additive solution is obtained;

[0023] 2) Dissolve 100 parts of type B gelatin in 90 parts of water, fully swell, add 20 parts of glycerin, 1 part of preservative and 2 parts of titanium dioxide, mix evenly for gelation, the gelation temperature is 80 °C, and then Evaporate 94% of the water at 80°C to obtain the rubber compound;

[0024] 3) Use the α-Gal-β-CD additive liquid obtained in step 1) as the soft capsule additive liquid, and use the rubber material obtained in step 2) as the soft capsule rubber material for filling to obtain α-galactosidase soft capsule feed additive

Embodiment 3

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...
