Test device for measuring stability of beer foam

Abstract

The invention provides a test device for measuring the stability of beer foam. The test device comprises a foam thermostat, a gas dispersion head, a thermostatic device, a pulley block and a CO2 gas bottle, wherein all the members are distributed and connected according to a gas pipeline and a constant-temperature water circulating path of a system. The test device provided by the invention can be used for researching a dynamic de-foaming process of the beer foam, evaluating the stability of the beer foam, the collection of active substances of the foam and a relation between the active substances of foam and the foam stability, and the like. The test device for measuring the stability of the beer foam has the characteristics of simple structure, low cost and easiness in operation.

Description

technical field

[0001] The invention relates to the technical field of measuring beer foam, in particular to a test device for measuring the stability of beer foam. Background technique

[0002] Foam is a typical feature that distinguishes beer from other alcoholic beverages. It is also an important evaluation index of beer quality and an important characteristic that determines consumers' willingness to purchase. Structurally, the foam is composed of a gas phase, a liquid phase, and a surface-active component that stabilizes the foam. In the traditional beer foam detection method, the gas phase required for the formation of foam is the CO carried by the beer itself. 2 supply. During the foaming process, the CO of the beer itself 2 Released under external force (dumping) or decompression, at the same time, the inherent surface active components (such as protein, α-acid) of beer itself dissociate to the surface of the gas phase and solidify into the bubble wall, making the...
