摘要
[目的]研究浒苔的快速干燥方法,为浒苔的加工利用提供依据。[方法]采用L9(33)正交设计法对浒苔三级脱水干燥进行了优化选择。[结果]烘干温度对浒苔叶绿素含量的影响显著(P<0.05),其次是时间和风量;浒苔三级脱水干燥的优化参数为温度60℃、风量1 500 m3/h、时间30 min。[结论]采用烫漂、压榨、回转干燥三级脱水技术,分阶段对浒苔进行脱水干燥,避免了单一脱水干燥的缺点,有效地降低了浒苔叶绿素等营养物质的损失。
[Objective] The quick-drying method of E.prolifera was studied to provide scientific reference for its processing and utilization.[Method] Orthogonal design of L9（33） was chosen to optimize 3-level drying technology of E.prolifera.[Result] The effect of drying temperature on chlorophyll content in E.prolifera was significant（P〈0.05）,followed by time and air quantity;the optimization coefficient of 3-level drying technology of E.prolifera were temperature 60 ℃,wind amount 1 500 m3/h and time 30 min.[Conclusion] The 3-level drying technology of scalding,extrusion and turn drying on E.prolifera was studied to avoid the shortcoming of single drying,and lower the loss of chlorophyll effectively in E.prolifera.
