The application of the rosa roxburghii fruit wine composite clarifying agent is to use the rosa roxburghii fruit wine composite clarifying agent as a clarifying agent in rosa roxburghii fruit wine to be clarified, and the application mode is that the rosa roxburghii fruit wine composite clarifying agent is added into the rosa roxburghii fruit wine to be clarified according to the addition amount of 0.5% of the volume fraction, stirred in a water bath at 50 ℃ for 90min and then kept stand at normal temperature for 48h, so that the rosa roxburghii fruit wine can be clarified.
The reason for selecting the raw materials in the technical scheme is as follows:
the konjac glucomannan is a natural macromolecular heteropolysaccharide which is separated and extracted from konjac tubers and is connected by glucose and mannose through beta-1, 4 glycosidic bonds, has wide sources, good expansibility after being dissolved in water and high solution viscosity.
The carrageenan is curdlan extracted from red algae by thermokalite separation, can form thermoreversible gel by double helix crosslinking, has excellent gel property and rheological property, and can be prepared into composite gel with konjac glucomannan, sodium carboxymethylcellulose, xanthan gum and the like to enhance the gel strength.
The sodium carboxymethyl cellulose is a high-polymerization cellulose ether prepared by using cellulose, caustic soda and chloroacetic acid as main raw materials, is an anionic linear substance, is used as an additive in food, and has thickening and stabilizing functions.
The chitosan can interact with negatively charged microparticles in the wine body solution to flocculate and precipitate the turbid colloidal particles such as protein, pectin, tannin and the like in the wine. The method is reported to be applied to the clarification of wine such as crisp plum fruit wine, black garlic and red date wine, grapefruit fermented wine, green plum wine, beer and the like.
Uio-66 is a material formed by coordination of metal zirconium ion as metal ion source and terephthalic acid organism as ligand, has three-dimensional micropore structure of octahedral center hole cage and octahedral angle cage, and can be used as an adsorbent due to its large specific surface area. In recent years, with the rapid development of metal organic framework materials, the metal organic framework materials have important application in the field of dye adsorption, and have been reported to have certain adsorption effect on heavy metal ions such as copper, lead, cadmium and the like in water and dyes such as methylene blue and rhodamine B.
Compared with the prior art, the invention has the following beneficial effects:
the konjac glucomannan is selected as the main raw material, the good expansibility and the cohesiveness of the konjac glucomannan can obviously increase the adsorption capacity of the composite clarifier to incompatible impurities such as burrs and the like, and the added Uio-66 can improve the adsorption effect of the composite clarifier to substances such as pigments and the like, so that the rosa roxburghii fruit wine is transparent and clear, the clarity of the fruit wine is improved, and the quality of the fruit wine is improved; the compound clarifying agent prepared by the invention can effectively maintain the flavor and the nutritive value of the rosa roxburghii fruit wine and improve the stability of the fruit wine; the invention has simple operation and easy implementation, and is worth popularizing and using.
