1、狒猴桃果啤工艺研究食品科学与工程乔沛沛[摘要]啤酒市场的竞争日益激烈,消费者的口味也趋于多元化。因而用于酿洒的原辅料越来越丰富。各类啤酒相继面市,如枣啤、姜啤、青棵啤等。果汁啤酒风味独特。有着广阔的市场潜力,而我国的研究尚处在起步阶段。木实验以狒猴桃果汁和麦芽为主要原料,结合低温啤洒发酵工艺制作酿造型獗猴桃果啤。通过单因素和正交实验,分别研究了果胶酶加入量,温度,保温时间对狮猴桃澄清的影响,以及研究了狐猴桃汁添加量,獗猴桃汁的添加时期,酵母添加量对发酵过程屮獗猴桃啤酒品质的影响,最终确定了最佳的工艺条件。结果表明:在獗猴桃汁澄清处理屮,
2、果胶酶用量1.0g/1,温度50°C,时间120min,为最好的处理条件。在此处理条件下,制得的猫猴桃果汁清亮,透明。在猫猴桃果啤发酵处理中,獗猴桃汁添加屋为12%,酵母添加量为0.4%,在发酵后期添加,为最适发酵条件。在此发酵条件下,制得的狒猴桃果啤外观金黄透明,泡沫丰富,果香浓郁,口味醇正。本课题对琳猴桃果啤生产具有一定的指导意义。[关键词]獗猴桃汁;果啤;工艺研究StudyonTechnologyofKiwiFruitBeerFoodScienceandEngineeringQIAOPei-peiAbstract:Increasi
