摘要
研究了超高压处理丹阳封缸酒对其中9种有机酸的影响。先通过单因素实验和感官评价确定了在400 MPa、20 min条件下处理封缸酒,再用高效液相色谱分析超高压处理前后封缸酒中有机酸的变化。结果表明,经过高压处理后,酒中酒石酸、草酸、苹果酸和乙酸的含量增加,丙酮酸、酮戊二酸、乳酸、柠檬酸和琥珀酸的含量降低;感官分析表明,高压处理后的封缸酒口感和风味得到改善,更易让人接受。
The effects of ultra-high pressure treatment on the content of nine kinds of organic acids in Danyang Fenggang rice wine were investigated.Firstly,sensory evaluation was carried out through single factor experiment for Fenggang rice wine treated by 400 MPa for 20 min,then the change in organic acids content in the rice wine before and after ultra-high pressure treatment was analysed by HPLC.The results showed that after the treatment,the content of tartaric acid,oxalic acid,malic acid and acetic acid increased,while the content of pyruvic acid,ketone glutaric acid,lactic acid,citric acid and succinic acid decreased.Sensory evaluation indicated that the taste and the flavor of Fenggang rice wine got improved and was more acceptable after ultra-high pressure treatment.
