Study on caramel flavor jujube juice by Lingwu long shope jujubes

灵武长枣营养丰富,但近年来在产品加工转化方面深入研究不够,深加工产品单一,营养损失严重。针对以上问题,本文以灵武长枣为原料,开发出一款新型枣清汁饮品,达到理想的色泽、香气和协调的口感。研究确定了灵武长枣饮料的最佳配方,即焦枣汁17.99%,枣清汁55.00%,蔗糖2.95%,糖酸比为53∶1。此配方下饮料的感官评分96.50,可溶性固形物含量7.83%,黄酮含量0.0227mg/mL,总酚含量0.1690mg/mL。灵武长枣清汁饮料酸甜爽口、柔和细腻、余味清香,且工艺简单,极具工艺化生产价值和开发前景广阔。
