梵净山野生阳荷水溶性膳食纤维的工艺研究

Study on technology research of wild Zingiber striolatum in Fanjing mountain’s water soluble dietary fiber

摘要: 以梵净山野生阳荷为材料,采用超声波法在提取功率、温度、时间和料液比4个单因素实验的基础上,用L9(34)正交实验法,对野生阳荷水溶性膳食纤维(SDF)的工艺条件进行了优化。结果表明,最佳工艺条件为:提取时间39min、超声功率120W、浸提温度63℃、料液比1∶41(g/mL),在此优化条件下,SDF的提取率为3.33%。

Abstract: Wild Zingiber strioatums in Fanjing Mountain were materials and ultrasonic method was used, based on 4 fundamental single factors, these were power extraction, temperature and time and ratio of material to liquid, by means of L9 (34) orthogonal test, process conditions were optimized about water-soluble dietary fiber of Wild Zingiber strioatums. The results showed that the optimal technique conditions were extraction time was 39min, ultrasonic power was 120W, extraction temperature was 63℃ , solid -liquid ratio was 1∶41g/mL. Under these optimum conditions, the SDF extraction rate was 3.33%.
