Research On Brewing Technology Of Physalis Wine

In this paper, Physalis was used as materials to study preliminary systematically on brewing technology of Physalis wine. This paper optimized the brewing technology of Physalis wine and determined the optimum process parameters by the PB and response surface design,while studied on the wine nutrients, clarification methods, blending method.The main findings are as follows:1. The main factors affect the wine is fermented.which is fermentation temperature, sugar content and SO2 addition. Optimum fermentation conditions were:fermentation temperature was 26.46?, sugar content was 22.33%, Addition of SO2 was 63.79mg/L. In the brewed wine,flavonoid content was 80.08 ?g/mL, saponin content was 86.56 ?g/mL.2. It was found that Physalis wine clarification, bentonite, chitosan and gelatin-tannin can make light transmission rate was more than 93%, PVPP and egg white to clarify the Physalis wine can makes the light transmittance was more than 91%. By taking into account the cost of production and refining effect,gelatin-tannic was recommended in industrial production.3. By the response surface, the study found the best blend method for Physalis wine was:add alcohol to make alcohol content reaches 12%, glucose was added so that the total sugar content of 55.5 g/L, add citric acid content of the total 5 g/L.
