漆蜡是从漆树果实中提取的天然植物油脂,具有极高的药用、保健价值和加工利用价值。为进一步探究漆蜡理化特性,为其开发利用提供理论基础,本实验采用GC-MS法和X -衍射技术,分别对高温处理漆蜡的脂肪酸成分和晶体特性进行测定,研究高温对其脂肪酸成分和晶体特性的影响。结果表明:高温处理漆蜡脂肪酸成分与含量发生改变,其饱和脂肪酸总含量升高,不饱和脂肪酸含量降低;不同温度处理之间漆蜡脂肪酸成分基本相同,脂肪酸含量存在差异。高温120 ℃处理1 ~ 3 h不能改变漆蜡晶体类型,但衍射峰值发生了改变;高温120 ℃处理4 h和5 h一定程度上影响了其晶体类型,在衍射角2θ 为11.79°、13.83°和18.17°处均...

Lacquer wax,as a natural vegetable wax extracted from the pericarp of fruits of Toxicodendron vernicifluum is ofvery high medical,healthcare and processing & utilization value.In order to explore physicochemical properties of lacquer wax to provide theoretical basis for its development and utilization,the effect of high-temperature treatment on its fatty acid composition and crystalline properties were studied in this paper.And they were determined by GC-MS method and X-ray diffractometer technology,respectively.Results showed that the fatty ac...
