贡柑果酒酿造工艺的研究

Research on brewing techniques of Gonggan oranges wine

以贡柑为原料,经打浆、酶解和脱苦等预处理,对贡柑果酒酿造的工艺参数等进行研究;以初始pH值、接种量、SO2添加量和发酵温度为因素,做4因素3水平的正交试验。结果表明,贡柑果汁经0.6%β-环糊精处理80min,酵母接种量为0.06%,二氧化硫添加量为90mg/L,初始pH值为4.5,发酵温度为33℃,发酵周期为7d,可得到浅黄色、澄清透明、风味好、营养丰富的贡柑果酒。

Gonggan orange which was used as material through shelling, beating and hydrolysis with pectin enzymatic, debitterization with β-cyclodextrin, addition of sugar and acid, filtering, fermentation with the yeast, was made into orange wine. The Gonggan fruit was debitterized with 0.6% β-cyclodextrin for 80min. Through the single-factor and orthogonal experiment, the optimum technological conditions of fruit fermentation were as followed, inoculation volume of 0.06%, SO2 90mg/L, pH value 4.5, fermentation temperature 33℃, and time 7d. The produced orange wine had advantages in light yellow, transparent, sapid and nutritional abundance.
