中文摘要: 澄清是猕猴桃果酒酿造的关键技术之一,直接关系着果酒的品质和贮藏。以四川宜宾野生猕猴桃为原料全果 发酵酿制猕猴桃干酒,研究果胶酶的添加量、4 种常用澄清剂对其澄清度和稳定性的影响。结果表明,添加 80 mg/L 的果 胶酶有助于酒体的澄清,混合澄清剂的最佳配比为皂土 0.45 g/L,明胶 0.65 g/L,壳聚糖 0.55 g/L,在此条件下果酒的澄清 度可达 95.42 %。复合澄清剂处理后,猕猴桃果酒的酒精度为 11.4 %,总糖 3.4 g/L,干浸出物 13.4 g/L,滴定酸 6.32 g/L,维 生素 C 190 mg/L,达到了干型果酒的国家标准。澄清处理的果酒在室温下保藏 7 个月后未发现沉淀物质。
Abstract:Process of clarification was one of the key technologies in kiwi wine brewing, which was directly re- lated to the quality and storage of the wine. The Yibin Sichuan wild kiwi fruit was used as raw material to brew for whole fruit fermentation dry wine, and the effect of pectinase dosage and four kinds of clarifier on clarifica- tion and stability of the dry wine was studied. The results showed that, 80 mg/L of pectinase was beneficial for the wine clarification, and the best ratio of mixing clarifiers were bentonite 0.45 g/L, gelatin 0.65 g/L, chitosan 0.55 g/L, respectively. After the treatment of compound clarifies, the clarity of kiwi wine could reach up to 95.42 %, and the component of kiwi wine were as follows, alcohol 11.4 %, total sugar 3.4 g/L, titratable acidity 6.32 g/L, dry extract13.4 g/L, vitamin C 190 mg/L, which reached the national standard of dry wine. The sedi- ment can not be found in Kiwi wine under room temperature after seven months.
