摘要/Abstract

摘要：

对火棘色素和果胶的综合提取工艺条件进行研究。先采用乙醇浸提法提取火棘色素，后采用盐酸水解法提取火棘果胶，并分别采用L9(33)和L9(34)正交试验对色素和果胶提取工艺进行优化。结果表明：火棘色素的最佳提取工艺为提取温度90℃、提取时间2h、料液比1:20(m/V)，此条件下火棘色素粗提物的提取率为25.31%；用盐酸水解已提取色素的火棘渣提取火棘果胶，最优工艺条件为提取温度90℃、提取时间2.5h、pH1.5、料液比1:25(m/V)，此条件下的火棘果胶提取率为4.72%。该工艺设备投入低、工艺简单、适合大规模生产。

Abstract:

The fruit pigment of Pyracantha fortuneana was extracted into aqueous ethanol solution, and the residue was then hydrolyzed with hydrochloric acid to obtain pectin existing in the supernatant. Orthogonal array designs L9(33) and L9(34) were used to optimize the extraction processes for pigment and pectin. The optimum conditions for pigment extraction were as follows: extraction temperature 90 ℃; extraction time 2 h; and solid-to-liquid ratio 1:20 (m/V), which gave a crude pigment yield of 25.31%, and those for pectin extraction were as follows: extraction temperature 90 ℃; extraction time 2.5 h; initial pH 1.5; and solid-to-liquid ratio 1:25 (m/V), under which a pectin yield of 4.72% was achieved. The two processes are of low-cost equipment investment and simplicity, thereby being suitable for massive production.
