The Influence of Biomolecule Composition on Colloidal Beer Structure

Abstract

Recent studies have revealed an interest in the composition of beer biomolecules as a colloidal system and their influence on the formation of beer taste. The purpose of this research was to establish biochemical interactions between the biomolecules of plant-based raw materials of beer in order to understand the overall structure of beer as a complex system of bound biomolecules. Generally accepted methods of analytical research in the field of brewing, biochemistry and proteomics were used to solve the research objectives. The studies allowed us to establish the relationship between the grain and plant-based raw materials used, as well as the processing technologies and biomolecular profiles of beer. The qualitative profile of the distribution of protein compounds as a framework for the formation of a colloidal system and the role of carbohydrate dextrins and phenol compounds are given. This article provides information about the presence of biogenic compounds in the structure of beer that positively affect the functioning of the body. A critical assessment of the influence of some parameters on the completeness of beer taste by biomolecules is given. Conclusion: the conducted analytical studies allowed us to confirm the hypothesis about the nitrogen structure of beer and the relationship of other biomolecules with protein substances, and to identify the main factors affecting the distribution of biomolecules by fractions.

The Study of Mineral Elements Participation in Brewing Products Foam Structure Formation

“…According to Table 1 data, the nitrogen content with thiol groups is most closely related to the foam height (r 0.99), and Co 2+ ions (r -0.75) are less strongly related to the foam height, and most organic compounds have a high correlation between themselves (correlation coefficients are highlighted in green in the Table 3). The relationship between nitrogen with thiol groups and the foam height is natural, since it is due to SH-groups that the foam structure is formed [15].…”
