Citrus fruit vinegar prepared by composite strain mixed fermentation and preparation method thereof

Abstract

The invention relates to a citrus fruit vinegar prepared by composite strain mixed fermentation, belonging to the technical field of fruit vinegar brewage. The preparation method is characterized by comprising the following steps: 1) preparing a composite microzyme strain seed solution; 2) preparing a composite acetobacter strain seed solution; 3) preparing a glutinous rice saccharified solution; 4) preparing a citrus juice; 5) preparing a fermentation liquid; 6) carrying out alcohol fermentation; 7) carrying out acetic fermentation; and 8) aging at room temperature for 2-3 months, filtering with diatomite, and clarifying to obtain the citrus fruit vinegar finished product. By using the citrus and glutinous rice as the raw materials and adopting the fruit/grain co-brewage and composite strain mixed fermentation, the prepared citrus fruit vinegar has the advantages of abundant nutrition, favorable mouthfeel, pleasant fruital aroma and no bitterness.

Problems solved by technology

Compared with the liquid fermentation method, the solid-state fermentation method has the advantages of good flavor and good taste, but there are disadvantages such as long fermentation period, high labor intensity, difficult to control the fermentation process, and easy to be contaminated by bacteria.

The advantage of the liquid fermentation method is that the fermentation cycle is short, the labor intensity is small, the fermentation process i...
