Abstract

The objective of the study is to study, evaluate the production process and analyze the quality of rice wine in Trung Thanh, Co Do district, Can Tho City. The study investigated the production situation of rice wine in Trung Thanh. The results showed that there were households producing rice wine under stable operating conditions. Most households process rice wine in the traditional way, the processing formula is based on experience, investment in science and technology, equipment, machinery, and no factory. Assessing the quality of rice wine produced in Trung Thanh using some physical and chemical indicators (humidity, brix, alcohol, acid content, pH) and microbiology (yeast, mold, lactic acid bacteria), it was found that the humidity of rice wine is in the range of 34% - 41,67% w/w, alcohol content is at 10 - 12% v/v, brix is 31 - 43 ^oBrix, pH is 3,9 - 4,19, lactic acid content is 0,8 - 1 mg/mL. The density of yeast and mold fluctuates at 7,04 – 7,26 Log₁₀CFU/g, lactic acid bacteria are also found to fluctuate at 8,05 – 8,31 Log₁₀CFU/g.
