沙棘油提取工艺研究

本文研究了种子粒度、提取时间、溶剂用量等对沙棘油粗品最大得率的影响。结果表明:种子粒度和溶剂用量是影响提取效率的显著因子;提取时间对提取效率有影响,但不显著。当提取时间为6h,粉碎粒度为40目,溶剂用量为6倍量时,提取效果最好。

Study on ExtractionTechnique of Oil of Hippophae rhamnoides L

This paper studied extraction technology of oil of Hippophae rhamnoides L. The main results are as follows: the effects of operating parameters such as granularity of seeds, extraction time and amount of extractant on the highest yield of rude oil from seeds of Hippophae rhamnoides linn (extraction efficiency) were further detected.The ruslt showed that the granularity of seeds and amount of extractant were the significant factors affecting the efficiency of oil of Hippophae rhamnoides linn extraction. While the extraction time had influence (not significant) on the extraction efficiency. When the optimum extraction technique condi- tions was obtained as follows: extraction time was 6 hours, granularity of seeds was 40 mesh, amount of extractant was 6 diameters. Thus it can provide some referable data for others ’study on extraction of oil of Hippophae rhamnoides L.
