Embodiment 1

[0043] Mix β-mannanase, ferulic acid esterase and cellulase according to the mass ratio of 1:2:10 to make a mixed enzyme preparation; then uniformly mix with destarched wheat bran according to the mass ratio of 1:20, and seal Enzymatic hydrolysis in a water bath at 40°C for 24 hours; the enzymatic hydrolyzate was sterilized at 120°C and centrifuged at a speed of 5000r / min for 60min, and the supernatant was evaporated at a temperature of 110°C to obtain the enzymatic hydrolyzate of wheat bran. The mass content of mannan and the mass content of ferulic acid in the enzymatic hydrolysis product of wheat bran are greater than 35% and 28% respectively, as measured by liquid chromatography.

Embodiment 2

[0045] Mix β-mannanase, ferulic acid esterase and cellulase according to the mass ratio of 1:3:8 to make a mixed enzyme preparation; then uniformly mix with destarched wheat bran according to the mass ratio of 2:18, and seal Enzymolysis in a water bath at 35°C for 24 hours; the enzymolysis solution was sterilized at 120°C and centrifuged at a speed of 5000r / min for 30 minutes, and the supernatant was evaporated at a temperature of 100°C to obtain the enzymatic hydrolysis product of wheat bran. The mass content of mannan in the enzymatic hydrolysis product of wheat bran is greater than 38%, and the mass content of ferulic acid is greater than 30% as measured by liquid chromatography.

Embodiment 3

[0047] Mix β-mannanase, ferulic acid esterase and cellulase according to the mass ratio of 1:5:6 to make a mixed enzyme preparation; then uniformly mix with destarched wheat bran according to the mass ratio of 2:15, and seal Enzymolysis in a water bath at 40°C for 12 hours; the enzymolysis solution was sterilized at 120°C and then centrifuged at a speed of 3000r / min for 60 minutes, and the supernatant was rotary evaporated at a temperature of 100°C to obtain the enzymatic hydrolysis product of wheat bran. The mass content of mannan and the mass content of ferulic acid in the enzymatic hydrolyzate of wheat bran are greater than 42% and 33% respectively, as measured by liquid chromatography.

Abstract

The invention discloses an aquatic sugar metabolism regulating composition, a preparation method and application thereof. The feed additive comprises 3-25 parts of resveratrol, 2-20 parts of seabuckthorn seed flavonoids and 470-490 parts of wheat bran enzymatic hydrolysis product. The feed additive uses resveratrol, seabuckthorn seed flavonoids and wheat bran enzymatic hydrolysis products as raw materials, and makes full use of plant active ingredients with different biological structures for scientific compatibility. The regulation and mechanism of sugar metabolism in bream and carp are highly pertinent. The present invention combines the growth and physical and chemical index results of related breeding tests to prove that the feed additive can significantly improve the function of fish islet beta cells, and further improve the secretion and release of insulin.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to an aquatic sugar metabolism regulating composition and a preparation method and application thereof. Background technique [0002] Among the three major nutrients, sugar is the cheapest. Adding an appropriate amount of sugar in the feed can not only save the amount of protein and fat, reduce the cost of feed, but also reduce the catabolism of protein, reduce the discharge of ammonia nitrogen from fish, and then reduce the pollution of water bodies. However, compared with mammals, the ability of fish to utilize carbohydrates as an energy source is limited. Excessive sugar levels in the feed not only have a severe negative impact on growth performance, but also lead to metabolic dysfunction, which in turn impairs immune function. In view of this, exploring the mechanism of glucose metabolism disorder and seeking scientific and effective means to improve the glucose metaboli...
