Method for removing colloid components in medicinal liquor

Abstract

The invention provides a method for removing colloid components in a medicinal liquor. The method comprises the following steps: adding sodium hydrogen carbonate to an acidic medicinal liquid extract of a mixed system containing the colloid components to adjust the pH to neutrality, adding an electrolyte aluminum potassium sulfate having an amount being 0.1%(w / m) of the quantity of the extract, uniformly stirring, and allowing the obtained solution to stand for 5 days, taking the resultant supernatant to prepare the liquor, and filtering. The method solves problems comprising long production period, large energy consumption and much loss of traditional technologies, and enables the liquor to have a good physical stability in a low temperature environment and the efficacy loss and the component loss of the liquor to be small.

Description

technical field [0001] The invention relates to the field of preparation of alcoholic beverages, in particular to the elimination of relatively stable colloids or similar colloids suspended in medicinal wine. Background technique [0002] The problem of cold turbidity in medicinal wine has a long history. The fundamental reason is that the raw medicinal materials contain a large amount of colloidal substances such as protein and starch, which are often suspended in medicinal wine in a relatively stable colloidal or similar colloidal state. Most of the traditional production processes use low-temperature freezing combined with diatomite filtration to remove these colloidal substances. This process takes a long time to freeze and consumes a lot of energy. At the same time, the frozen wine is often not completely clarified due to factors such as the quality of medicinal materials and unstable freezing temperature. It makes it difficult to filter the wine, and the loss of functi...

AI Technical Summary

Problems solved by technology

[0004] According to the physical and chemical theory of colloids, the present invention reduces the mutual repulsion of the colloidal particles in the solution by adding chemical substances to neutralize the charges carried by the colloids in the medicinal wine, thereby making them coagulate and settle faster, solving the problem of long production cycle of the traditional process, The problem of high energy consumption and loss reduces the production cost, and the physical stability of wine is better in low temperature environment, and the loss of functional components is less
