| 摘 要： | 以天津宝坻产区的三种葡萄为原料,分别从自然发酵的葡萄汁中筛选出340株酵母菌,经生理生化,产酸、酯、尿酶、H2S,发酵能力测定及26SrRNA测序,确定4株为酿酒酵母,用于贵人香低醇白葡萄酒的酿造。以商用酵母为对照,定量分析了不同酵母所酿酒中的香气成分、氨基甲酸乙酯含量,并进行了理化指标和感官测定,发现酵母C508和G611酿造的低醇酒具有更独特的香气特点,氨基甲酸乙酯的含量较低,微生物稳定性较高,更适合低醇酒的酿造。

| Abstract: | In order to identify the Saccharomyces spp.associated with spontaneous fermentation of three different grape varieties(Italian Riesling,Muscat and Cabernet Sauvignon grapes)from Tianjin Baodi wine region and to evaluate the micro-fermentation performance of low-alcohol white wine.The indigeous yeast flora isolated during fermentation was studied and analyzed.Firstly,yeasts were identified to genus level by growth on WL nutrient agar and the tests of assimilation carbon and nitrogen source and so on.Later,fo... |
