微波法提取鱼鳞色素研究

目的]探讨微波技术提取锦鲤鱼鳞总色素的适宜条件,并与振荡浸提法进行比较。方法]采用单因素试验设计,以石油醚为提取溶剂,在不同辐射功率（160～800W）和辐射时间（60～180s）微波处理下,测定相同质量鱼鳞色素提取液的吸光度。结果]微波辐射功率为640W、辐射时间为150s的条件下,鱼鳞总色素提取效率最高;微波法（辐射功率为640W,时间为150s）提取鱼鳞总色素的效果比振荡法（提取温度为30℃,时间为3h）差。结论]建立了微波技术提取鱼鳞色素的适宜条件。

Study on the Microwave Extraction of the Pigment for the Fish Scale

Objective] The aim was to study extraction conditions on pigments of fish scale and compare extraction efficiencies between microwave and shaking extractions.Method] Pigments of the fish scale were extracted using the microwave method under different power (160-800 W) and time(60-180 s)with the petroleum ether as the extracting solution,and the absorbance of extracting solution was determined under the wavelength of 340 nm.Result] Extraction efficiency was highest with the extraction power of 640 W and t...
