Whole grain adlay and dehulled kernels stored at room temperature ( about 25℃), 15℃ and 5℃ were used as raw materials. Completed random design and factorial experimental design were adopted to analyze the changes of coixenolide content, fatty acid distribution and physicochemical properties ( including acid value and peroxide value ) of the adlay oil extracted from the materials in order to find more suitable storage condition.

摘要本研究探讨薏苡籽实，以带壳状态和脱壳后的糙薏仁粒分别贮存於常温(约25℃)，15℃及 5℃之下，利用 CRD 和复因子试验设计定期取样分析籽实在贮藏六个月期间薏仁油中薏仁酯含量，脂肪酸组成，以及薏仁油理化特性之变化，以期找寻薏苡籽实的较适贮存条件。

The removal of these impurities by three kinds of active carbon(coaly activated carbon,fruit hull activated carbon,woodiness activated carbon) are studied under different experimental conditions.The results show that the fruit hull active carbon is not suitable for the removal of the impurity in bittern of salt lake because its removing rate of COD and turbidity is ...

以去除盐湖卤水中COD和浊度为目的，选用煤质活性炭、果壳活性炭、木质活性炭3种不同活性炭进行净化除杂的工艺研究，结果表明：果壳活性炭对COD和浊度的去除率最低，加入量最大，不宜选用；木质活性炭在低温下(≤20℃)脱除COD效果较好，在常温下(28~45℃)去除COD和浊度的效率明显低于煤质活性炭；在震荡速度、吸附时间及吸附剂加入量均相同的情况下，煤质活性炭脱色除杂效果明显优于其余两种活性炭，在盐湖卤水的脱色净化工程中应优先选用。
