7、············9红枣-胡萝卜复合饮料的加工工艺研究红枣-胡萝卜复合饮料的加工工艺研究摘要：为了确定红枣-胡萝卜复合饮料的最佳工艺条件，以红枣和胡萝卜为原料，用酶法提取枣汁，通过正交试验确定枣汁的最佳浸提条件和红枣-胡萝卜复合饮料的最佳配方，在红枣-胡萝卜复合饮料中分别加入CMC（羧甲基纤维素钠）、黄原胶、海藻酸钠3种稳定剂，研究稳定剂对复合饮料的影响。经过试验得出结论，枣汁提取的最佳工艺条件为：加水量为枣重的5倍，果胶酶用量0．20％，在50℃下提取4h。红枣-胡萝卜复合饮料的最佳配方为：红枣汁40％，胡萝卜汁45％，蔗

8、糖8％，柠檬酸0．10％。选择海藻酸钠作为红枣-胡萝卜复合饮料的稳定剂，其适宜用量为0．15％。该复合饮料色泽红润，口感细腻，酸甜适口，具有浓郁的胡萝卜和红枣的复合香气，是集营养和保健于一体的天然饮品。关键词：红枣汁,胡萝卜汁,复合饮料，加工工艺R
