摘要
采用热水法提取火龙果花多糖,研究不同的加热温度、料水比、加热时间等3个单因素对火龙果花多糖提取量的影响,采用L9(33)正交试验确定最佳提取工艺参数。结果表明:在加热温度90℃、料水比1∶35、加热时间3h的条件下,火龙果花多糖的提取效果最好,为55.87mg.g-1。
Hot water was used for extracting polysaccharide from pitaya flower. Heating temperature, the ratio of solid to liquid, and heating time were three factors used separately in single factor test to analyze the influence of various factor on extraction efficiency. Orthogonal experiment design L9 （35） was applied to optimize the extraction parameters. The results showed that, with ratio solid ： liquid in 1 ： 35 and extraction temperature at 90℃ for 3h, the best extraction efficiency of polysaccharides from pitaya flower was obtained for 55.87 mg · g^-1
