摘　　要：选取壳聚糖、明胶、皂土、果胶酶4种澄清剂对石榴果酒分别进行澄清处理,以澄清度为指标,先通过单因素试验,确定4种澄清剂澄清石榴果酒的适宜添加量,在此基础上,通过分析不同澄清剂处理后石榴果酒的澄清度、酒精度、色差、色度及感官评分等指标,筛选出适合石榴果酒的澄清剂,并利用单因素及正交试验对其澄清工艺条件进行优化。结果表明,4种澄清剂均可提高石榴果酒的澄清度,皂土效果最好,果酒澄清度最高,感官评分最高(86.8分),且澄清后酒精度下降不明显。皂土最佳澄清工艺条件:添加量为0.70 g/L,处理温度为18℃,处理时间为8.0 h,此条件下,石榴果酒澄清度高达98.9%,果酒清澈透明、均一稳定,品质较佳。Chitosan,gelatin,bentonite,and pectinase were used to clarify pomegranate wine.With clarity as the index,the suitable amount of four clarifiers to clarify pomegranate wine was determined by single factor test.The suitable clarifier was selected by analyzing the clarity,alcohol degree,color,chroma and sensory evaluation of pomegranate wine.Clarification conditions were optimized by single factor and orthogonal tests.All four clarifiers improved the clarity of pomegranate wine.Bentonite was superior,with the highest clarity and sensory evaluation score(86.8 points),and negligible decrease in alcohol content following clarification.The optimum clarification conditions of bentonite were addition of 0.70 g/L,temperature of 18℃,and clarification time of 8.0 h.Under these conditions,a clear,transparent and uniform pomegranate wine with 98.9%clarity was obtained.
