Problems solved by technology

[0003] In the field of wine processing, freeze concentration technology has been applied to the concentration of grape juice in the past, so that its sugar content can reach the brewing standard, but it has not been applied to the concentrated wine after brewing.
In particular, the application of suspension freeze concentration technology to improve the quality of wine is still blank

Abstract

The invention discloses a preparation method and application of concentrated grape wine, and belongs to the technical field of grape wine. The concentrated grape wine is improved grape wine, and compared with raw wine, the concentration of main components of the concentrated grape wine is improved, and the sensory quality of the concentrated grape wine is improved. The invention also discloses a preparation method of the improved grape wine, namely the concentrated grape wine is prepared by using the integrated suspension freezing concentration device. Particularly, according to the suspension freeze concentration method, the component concentration of the concentrated wine liquid can be controlled by adjusting parameters set by integrated freeze concentration. Particularly, the improved wine is concentrated wine which has the typicality of brewed wine and is different from distilled wine. The concentrated grape wine and the preparation method thereof disclosed by the invention have the advantages of improving the concentration of grape wine components, improving the quality of the grape wine and highlighting the style of the grape wine, and are creative technical application of a suspension freezing concentration technology in the field of grape wine.

Description

technical field [0001] The invention relates to the technical field of wine, in particular to a concentrated wine and a preparation method thereof. Background technique [0002] Concentration refers to the process of removing the solvent part in the feed liquid to increase the content of the solute, and its essence is a separation process of the mixed components. Common concentration methods mainly include evaporative concentration, membrane separation concentration and freeze concentration. Evaporative concentration is to convert the solvent from liquid to gas by increasing the temperature, so as to separate it from the solution to achieve the purpose of increasing the concentration of the solute. Membrane separation and concentration use the selective permeability of filter membranes to separate solutes and solvents. Freeze concentration is to convert the solvent from liquid to solid by lowering the temperature, so that the solvent can be separated and removed from the s...
