摘要
本文以荷叶为主要原料,魔芋粉、蓝莓粉、玫瑰及低聚果糖为辅料,开发出一款具有清暑利湿、降脂减肥功效的荷叶复合固体饮料。首先,将荷叶预处理及干燥后,进行超微粉碎。研究了超微粉碎时间对荷叶粉体特性的影响,以粉末粒径、持水力、溶解性及黄酮溶出率为指标,优化最佳粉碎时间。结果表明:超微粉碎最佳时间为15min,粉体的平均粒径为18.19μm,持水力为3.49g/g,溶解性为0.11g/g,且黄酮溶出率高达46.32μg/g。在此基础上,以感官质量为指标,依次通过单因素和L9(34)正交试验,优化了原辅料的最佳配比,即:荷叶超微粉30%、魔芋粉15%、蓝莓粉25%、玫瑰粉20%及低聚果糖20%。
In this paper, with lotus leaf as main raw material, konjac flour, blueberry powder, rose and fructo-oligosaccharides as auxiliary materials, a kind of lotus leaf compound solid beverage with the effects of clearing internal heat and damp, as well as hyperlipidemia and adiposity therapy, was developed. Firstly, after pretreatment and drying of lotus leaf, it was treated by superfine grinding. Furthermore, the effects of superfine grinding time on the flour properties were investigated. The grinding time was optimized in term of particle size distribution, water holding capacity, water solubility and flavonoids solubility. The results showed that the optimal grinding time was 15min. Meanwhile, the medium particle size, water holding capacity, water solubility index, and flavonoids solubility were 18.19μm,3.49g/g, 0.11g/g, and 46.32 μg/g, respectively. On this basis, the ratio of raw materials and auxiliary materials was optimized in turn in single factor tests and a L9(34) orthogonal test in term of sensory quality. The optimal formula was lotus leaf powders 30%,konjac powders 15%, blueberry powders 25%, rose powders 20%, and fructo-oligosaccharides 20%.
