Description
技术领域:
本发明涉及一种果酒的加工方法,尤其是涉及一种龙眼果酒的加工方法。
背景技术:
四季水果可以延伸几百种甚至上千种果酒、果脯、果汁产品产业生产,不仅在中国销售市场前景广阔,在国外市场也定会大受欢迎,因为我们是资源大国,其他国家无法媲比,五大酒类市场全国一年大约5000亿销量,如果果酒连带产业兴起能够占领20—60%,那就是几百亿、几千亿的市场份额,前景不可想象。
发明内容:
本发明所要解决的技术问题是现有龙眼果酒在生产方法中存在的龙眼出汁率低、酶解效果不佳、果酒陈酿时间长、色泽不稳定等缺陷,提供一种营养丰富、口感浓郁、果味香醇且陈酿时间短、酵母菌纯正、酶解效果好的龙眼果酒加工方法。
本发明解决其技术问题所采取的技术方案是:一种龙眼果酒的加工方法,采用以下步骤:
A、原料预处理:挑选新鲜、无病害的龙眼经清洗,作为备用原料;
B、混合、打浆:将清洗过的龙眼与麸皮按一定比例混合,麸皮细度为60-70目,混合浸泡时间17-20小时,温度为40-50℃,做打浆处理;
C、复合酶处理:将果胶酶、纤维素酶和半纤维素酶按一定比例混合,按3-4%的重量比置于经过打浆处理的浆液中,温度控制为50-55℃,时间为4-5小时;
D、榨汁、过滤:将复合酶处理后的浆液榨汁,并过滤,制得龙眼果浆;
E、酶法澄清:向龙眼果浆中加入其重量0.5-1%的果胶酶,控制温度40-50℃,时间2-3小时,制得龙眼液;
F、超滤:采用壳聚糖-鱼胶结合的方法过滤龙眼液;
G、酵母菌种:从龙眼表面、栽培土壤等地分离果酒酵母,筛选适宜的酒母菌株,经过酵母筛选、扩大培养后,备用;
H、发酵:取步骤G中的酵母菌按重量比1-2%的比例加入步骤F中的龙眼液中,发酵温度为30-40℃,时间为10-15天;
I、超滤:采用壳聚糖-鱼胶结合的方法过滤,制得龙眼酒;
J、陈酿:采用微波辅助冷处理加速龙眼酒陈酿,微波功率500-1000MHz,冷处理时间5-10天,温度5-10℃;
K、包装、杀菌后制得龙眼果酒。
所述的步骤B中按一定比例为:龙眼为75-85重量份,麸皮为15-25重量份。
所述的步骤C中一定比例为:果胶酶为85-90重量份、纤维素酶为5-8重量份,半纤维素酶5-8重量份。
本发明具有以下优点: 本发明在龙眼打浆时采用龙眼与麸皮混合,提高了龙眼的出汁率;在酶解步骤采用多种酶混合,能够全面分解龙眼中的营养物质;在发酵时,采用经筛选、扩大培养的酵母菌,确保发酵液的口感纯正;超滤时,采用壳聚糖-鱼胶结合的方法,克服现有的过滤效果不佳的缺陷;陈酿中采用微波辅助冷处理的方法,减小了陈酿的时间。
具体实施方式:
实施例1:
A、原料预处理:挑选新鲜、无病害的龙眼80kg经清洗,作为备用原料;
B、混合、打浆:将清洗过的龙眼与20kg麸皮混合,麸皮细度为60目,混合浸泡时间17小时,温度为40℃,做打浆处理;
C、复合酶处理:取果胶酶2.6kg、纤维素酶0.2kg和半纤维素酶0.2kg混合,按重量比3%的比例置于经过打浆处理的浆液中,温度控制为50℃,时间为4小时;
D、榨汁、过滤:将复合酶处理后的浆液榨汁,过滤,制得龙眼果浆;
E、酶法澄清:向龙眼果浆重量中加入果胶酶0.3kg,控制温度45℃,时间2小时,制得龙眼液;
F、超滤:采用壳聚糖-鱼胶结合的方法过滤龙眼液;
G、酵母菌种:从龙眼表面、栽培土壤等地分离果酒酵母,筛选适宜的酒母菌株,经过酵母筛选、扩大培养后,备用;
H、发酵:取步骤G中的酵母菌1kg加入步骤F中的龙眼液中,发酵温度为40℃,时间为13天;
I、超滤:采用壳聚糖-鱼胶结合的方法过滤,制得龙眼酒;
J、陈酿:采用微波辅助冷处理加速龙眼酒陈酿,微波功率800MHz,冷处理时间7天,温度8℃;
K、包装:将杀菌后制得龙眼果酒装瓶包装。
以上所述仅为本发明的较佳实施例,凡依本发明权利要求范围所做的均等变化与修饰,皆应属本发明权利要求的涵盖范围。
