摘要
对"水蒸气蒸馏法"从废弃物柑橘皮中提取柠檬烯的提取工艺条件进行了优化改进,获得最优提取工艺条件为:提取温度为92℃,提取时间为150 min。并通过在提取过程中加入适量(质量为柑橘皮质量的3%)的氯化钠,进一步提高了提取率。将柠檬烯提纯获得天然的表面活性剂柠檬烯,并通过微乳化制备柠檬烯微乳体系。再将微乳柠檬烯体系、助剂、天然微纳米贝壳粉等制备三相微乳化的新型高效安全果蔬洗洁精。通过农药残留检测实验可知,该果蔬洗洁精对水果、蔬菜表面的农药去除效果及重金属去除效果比市面上的果蔬洗洁精效果更好,且经过测试,该产品的理化性能、稳定性能等各项指标均达到洗洁精类产品的国标要求。
The"steam distillation method"for extracting limonene from waste citrus peels was optimized and improved.The optimal extraction conditions were as follows:the extraction temperature 92℃and the extraction time 150 min.And by adding an appropriate amount of sodium chloride(the quality was 3%of the quality of the citrus peel)during the extraction process,the extraction rate was further improved.The limonene was purified to obtain the natural surfactant limonene,and the limonene microemulsion system was prepared by microemulsification.Then the microemulsion limonene system,additives,natural micro-nano shell powder were used to prepare a three-phase microemulsified high-efficiency and safe fruit and vegetable detergent.Through the pesticide residue detection experiment,it was known that the fruit and vegetable detergent had a more significant effect on the removal of pesticides and heavy metals on the surface of fruits and vegetables than the fruit and vegetable detergents on the market.The testing results showed that the product’s physical and chemical properties and stability met the national standard requirements of detergent products.
