中文摘要: 以山东微山湖红莲荷叶为主要原料,将超微粉碎技术应用于传统荷叶露生产工艺中。对荷叶露颜色、风味、澄 清度、稳定性、黄酮得率等方面进行研究。以黄酮得率和感官指标为依据,得到荷叶浸提液最佳制备条件:干燥荷叶经过 万能磨粉碎后再经过一次超微气流粉碎,中位径 D50 为 72.5 μm,在温度为 90 ℃,料液比为 1 ∶ 50(g/mL),提取时间为 20 min。荷叶风味饮料的最佳调配工艺条件,即白砂糖用量 3 %,柠檬酸用量为 0.08 %,VC 用量为 0.06 %,β-环状糊精 用量为 0.4 %,薄荷汁用量为 3 %。本研究选用硅藻土作为过滤介质对荷叶浸提液进行二次抽滤,可得到品质良好的荷 叶饮品,颜色和口味均令人满意。从而确定了一种新型高效荷叶功能饮料的生产工艺及配方。
Abstract:The paper studied the production technology of lotus leaf health beverage applied super fine crushing technique by lotus leaf of Weishan Lake red-violet as the raw material. It studied the product color,favor,the stability, especially the functional composition of leaf flavonoid content, etc. The best preparation conditions of lotus leaf extract: the size of material D50, solid/liquid ratio, the extraction time and the extraction temperature were 72.5 μm, 1 ∶ 50 (g/mL), 20 min and 90 ℃. The best mixing process conditions: the dosage of sugar, the dosage of citric acid, the dosage of VC, the dosage of beta cricoid dextrin and the dosage of mint juice were 3 %,0.08 %, 0.06 %, 0.4 % and 3 %. This research could get the lotus leaf extract by secondary filter used diatomite as the filter medium.
