The application discloses a compound flocculating agent and application thereof, and belongs to the technical field of flocculating agents. The compound flocculating agent comprises flocculating agent A and flocculating agent B. The flocculating agent A comprises attapulgite and bamboo charcoal, and the flocculating agent B comprises chitosan quaternary ammonium salt and polyacrylamide. The compound flocculating agent is applied to the flocculation of stevia extract liquid, and has the advantages of fast flocculation settling speed, low cost, simple operation, low loss rate of steviol glycosides, high clarification rate and good flocculation and impurity removal effects.

There is a need for a beer-flavored beverage which has a flavor suitable for a beer-flavored beverage even if a naturally derived sweetener is used, which is reduced in terms of inappropriate sweetness, and which is favorable in terms of other flavor characteristics. Provided is a beer-flavored beverage in which the content of lactic acid is 20-1800 mg / L and a stevia extract is contained at a quantity of less than 150 mg / L.

The application discloses a method for separating steviol glycosides and chlorogenic acid, comprising the following steps: concentrating a stevia extract by using a nanofiltration membrane to obtain a concentrated solution; adsorbing the concentrated solution by using a resin system composed of a series connection of LX-8 and LX-T28 resin columns; after the adsorption is completed, resolving the LX-8 resin column by using 60-80wt% ethanol solution alone to obtain a chlorogenic acid resolution solution, and resolving the LX-28 resin column by using 60-80wt% ethanol solution to obtain a steviol glycoside resolution solution; and after the chlorogenic acid resolution solution is concentrated, spray drying is performed to obtain chlorogenic acid; and after the steviol glycoside resolution solution is concentrated, spray drying is performed to obtain steviol glycosides. The method uses a series connection of resin systems to treat the concentrated stevia extract, and uses different adsorption resins to adsorb and separate steviol glycosides and chlorogenic acid in the stevia extract, and the method is simple and has high separation efficiency.

This invention belongs to the field of acidifier technology, specifically relating to an acidifier that can improve the health of breeding ducks and the hatchability of hatching eggs, its preparation method, and its application. The acidifier includes acidifier A and acidifier B. Acidifier A is prepared by mixing and adjusting the volume of calcium formate, acetic acid, lactic acid, monk fruit extract, and an immune enhancer; acidifier B is prepared by mixing and adjusting the volume of calcium propionate, citric acid, malic acid, stevia extract, and an antioxidant. This invention enhances the immunity and antioxidant capacity of breeding ducks and improves eggshell quality by intermittently and alternately adding the two acidifiers to their drinking water during the egg-laying period. Furthermore, by spraying a proportionally diluted mixture of the two acidifiers during the later stages of hatching, it improves embryonic calcium absorption and duckling shell-pecking rate, reduces embryonic mortality, and significantly increases the hatchability of hatching eggs. This invention is suitable for large-scale breeding and hatching of breeding ducks.
