The application discloses application of Fagopyrum cymosum root powder in preparation of products for improving egg quality or intestinal health of laying ducks, and belongs to the technical field of feed additives. The application provides application of Fagopyrum cymosum root powder in preparation of products for improving egg quality or intestinal health of laying ducks, and the Fagopyrum cymosum root powder can improve eggshell strength, yolk color and eggshell proportion, improve the content of aspartic acid, threonine, glutamic acid, glycine, cystine and leucine in yolk, improve the content of arachidonic acid and arachidonic acid in yolk, and reduce the content of saturated fatty acid in yolk; the Fagopyrum cymosum root powder can improve the activity of maltase in the mucous membrane of the jejunum of laying ducks, and can improve the diversity and abundance of intestinal flora of laying ducks. The application provides a new strategy for improving egg quality or intestinal health of laying ducks.

The application discloses a new application of Korla fragrant pear high-activity polysaccharide in promoting expression of small intestinal disaccharidase, and belongs to the technical field of functional food and medicine. In the application, Korla fragrant pear pulp is freeze-dried, ground, sieved, extracted with hot water, alcohol precipitated, decolorized and deproteinized, separated through a membrane filtration system, further purified through DEAE-Fast flow anion exchange column chromatography, and finally, Korla fragrant pear high-activity polysaccharide KPP-2-a is obtained. The application innovatively finds that KPP-2-a can effectively promote expression and activity of disaccharidase (lactase, sucrase and maltase) in the brush border of small intestinal mucosal epithelial cells, significantly improves secondary disaccharidase deficiency and related symptoms, excavates a new use of the Korla fragrant pear high-activity polysaccharide KPP-2-a and widens the application field thereof, provides a new means for intervention of secondary disaccharidase deficiency, and has a broad prospect and market value.

The invention belongs to the field of food processing, and particularly relates to a white hyacinth bean protein beverage and a preparation method thereof. The hyacinth bean protein beverage comprises the following components: cooked white hyacinth bean powder, sodium alginate and chlorogenic acid. The preparation method comprises the following steps: adding alpha-amylase, maltase and cellulase, carrying out enzymolysis, and carrying out colloid milling, homogenization, sterilization and cooling. The white hyacinth bean protein beverage prepared by the method is unique in flavor, fine and smooth in taste, free of obvious beany flavor and free of layering after standing. And the production process is simple, easy to control and suitable for industrial production.

This invention discloses a modified maltase adjuvant and its preparation method. The preparation method includes: dissolving maltase in phosphate buffer, adding a bifunctional coupling agent (N-hydroxysuccinimide-polyethylene glycol-dibenzocyclooctylene) for activation; then covalently grafting the activated maltase with a hydrophilic modifier and a functional small molecule (1-carboxybutyl-3-methylimidazolium salt); finally, purifying by ultrafiltration to obtain the modified maltase adjuvant. This invention constructs a stable covalent structure on maltase containing both hydrophilic segments and functional ionic liquids through sequential functionalization modification mediated by a specific coupling agent. The resulting adjuvant possesses excellent enzyme stability enhancement and catalytic auxiliary functions, significantly improving the thermal stability, catalytic efficiency, and reusability of various industrial enzymes. It exhibits the characteristics of "multiple effects in one agent" and strong versatility, making it suitable for multiple fields such as biocatalysis, food processing, and bioenergy.

The invention belongs to the technical field of biological medicines, and particularly relates to application of 1, 3-dicaffeoylquinic acid (1, 3-DCQA) in preparation of a medicine for improving glucose and lipid metabolism disorder. The invention discloses application of 1, 3-DCQA in nitraria tangutorum bobr to preparation of a medicine for improving glucose and lipid metabolism disorder, and proves that the 1, 3-DCQA is inhibited by glycosidase (sucrase and maltase) of the 1, 3-DCQA, so that intestinal flora is changed, then short-chain fatty acid acetic acid secretion is promoted, acetic acid is used as a signal molecule to activate a GPR43 signal channel, and further insulin sensitivity is improved. The effect of regulating glycolipid metabolism is achieved. The invention not only provides a solid experimental basis for medicinal development of 1, 3-DCQA in Nitraria tangutorum Bobr, but also provides a brand new action target and direction for research and development of novel medicaments for treating glucose and lipid metabolism disorders, and has important theoretical significance and wide clinical transformation prospects.
