Foam coffee alcohol fermentation beverage and preparation method thereof

Abstract

The invention relates to a foam coffee alcohol fermentation beverage and a preparation method thereof. Through extraction, dilution or dissolution with hot water, a coffee solution can be made. Distiller's yeast is used as a fermenting agent, and after sealed fermentation, the yeast is removed; and sugar or other food additives are added for allocation, so that the coffee alcohol fermentation beverage rich in foam is made. According to the foam coffee alcohol fermentation beverage and the preparation method thereof disclosed by the invention, a high-concentration caffeine-free coffee solution is used for fermentation, and yeast nutrient substances do not need to be added; post dilution is performed, so that the content of coffee solids in the fermentation solution is reduced, organic acids in the fermentation solution are diluted, the pH value of a mixed solution is increased, and the foam coffee alcohol fermentation beverage is healthier than an ordinary carbonated beverage; a temperature-reduction method and a filtering method are used for stopping fermentation, so that part of sugar in the fermented beverage can be reserved, and the foam coffee alcohol fermentation beverage is more coordinative and natural in taste and rich and prominent in flavor; and CO2 produced during alcohol fermentation and foam promoting substances such as protein, polysaccharide and esters in the coffee mutally react, so that the coffee foams are finer and smoother, and are loose and long-lasting.

Description

[0001] (1) Technical field

[0002] The invention relates to a foamed coffee alcohol fermented beverage and a preparation method thereof. The purpose is to try to use coffee for the preparation of alcoholic fermented beverages, thereby enriching the types of coffee products, extending the coffee processing industry chain, promoting the technological update of the coffee industry, and promoting the healthy and rapid development of the coffee industry in my country. The technology belongs to the technical field of food processing.

[0003] (2) Background technology

[0004] Coffee planting in my country was first introduced to Yunnan by French missionaries in 1892. At present, the annual growth rate of the domestic coffee market is more than 15%, while the annual growth rate of the markets in developed countries is only 2% to 3%. Although domestic coffee consumption only accounts for 80 billion yuan, it is expected to reach 1 trillion yuan in 2020 and 2 to 3 trillion yuan in 20...
