怀地黄保健饮料的研制

Development of a novel healthy drink with Rehmannia glutinosa

以怀地黄为原料,对怀地黄保健饮料的加工工艺进行了研究.以可溶性固形物含量为指标,在单因素的基础上,通过L(934)正交试验,确定了怀地黄的最佳浸提工艺:加热温度90℃、加热时间20 min、浸泡时间为5 h.以感官评价为指标,在单因素的基础上,通过L1(645)正交试验,确定了饮料的最佳工艺配方:糖10%,柠檬酸0.08%,料液比1∶1,Vc-Na 0.1‰.饮料澄清透亮,口味柔和独特、酸甜可口.

The clarifying rehmannia glutinosalibosch sanitary beverages process has been studied with reference to relevant documents and the basis of single factor test,through L16（45） orthogonal test on heated temperature and time of materials,soaking time for the orthogonal experiment design,through sensory evaluation and concentration of resolvable solid to determine the optimal extraction process conditions.Choosing suger degree,acidity,the ratio of sardenia to liquor,Vc-Na as the factors design the orthogonal experiment to determine the optimal conditions for local flavour.The results showed that：the optimal extraction conditions for the heated temperature of materials 90 ℃,heated time 20 min,soaking time 5 h;the best conditions for local flavour are suger degree 10%,acidity 0.08%,the ratio of sardenia to liquor 1：1,Vc-Na 0.1‰.
