Abstract

The invention belongs to the technical field of silica gel preparation for beer stabilizers, in particular to a silica gel for wheat beer stabilizers with poor cold resistance, and specifically relates to a preparation method of silica gel for wheat beer, which includes carbon nanotube treatment and extraction from banana peels pectin treatment and calcium chloride aqueous solution treatment. Compared with the prior art, the present invention has the following advantages: in the present invention, by mixing carbon nanotubes and spherical silica gel, the carbon nanotubes in the obtained intermediate material A are uniformly distributed, interpenetrating with spherical silica gel molecules to form a network crosslinked structure, and then Treat the pectin extracted from the banana peel to increase the adsorption sites on the surface of the obtained intermediate material B, and then treat it with an aqueous solution of calcium chloride to make it have a developed mesopore structure, further increasing the adsorption of silica gel, and the stabilizer has no effect on the beer taste. It will not be affected, can adapt to adsorption treatment under low temperature conditions, and can significantly improve the cold stability of beer, thereby increasing the shelf life of beer.

Description

technical field [0001] The invention belongs to the technical field of silica gel preparation for beer stabilizers, and in particular relates to a preparation method of wheat beer silica gel. Background technique [0002] There are many factors that cause beer turbidity and precipitation in the later stage, the main reason is the formation of a sensitive protein-polyphenol substance mixture. To eliminate the turbidity and precipitation of beer, in addition to strict control of raw materials and production processes, a more effective method is in the beer. A non-biological stabilizer is added in the beer production process. Because the surface of silica gel contains silicon hydroxyl groups, it can specifically adsorb sensitive proteins in beer. It can be used as an effective protein adsorbent in beer production. Through continuous research on silica gel products, it is known that For different silica gel products, the protein adsorption effect of silica gel under different st...
