提取因素对木瓜籽油提取率的影响

Effect of Extracting Factors on Extraction Rate of Papaya Seed Oil

[目的]研究不同因素对木瓜籽油提取率的影响,确定木瓜籽油提取的最佳工艺条件。[方法]以市售光皮木瓜中的木瓜籽为试材,采用索式提取法提取木瓜籽油,通过单因素和正交试验,探讨不同的提取时间、液料比和提取温度对木瓜籽油提取率的影响,确定木瓜籽油提取的最佳条件。[结果]单因素试验表明,木瓜籽油提取的最佳提取时间为9 h,最佳液料比为8∶1,最佳提取温度为45℃。在此基础进行的正交试验表明,木瓜籽油提取的最佳提取条件为:提取时间9 h、液料比7∶1、提取温度为48℃,在此条件下,木瓜籽的出油率为28.77%。[结论]该研究为木瓜的综合利用和新产品的开发提供参考依据。

[Objective] The objective was to study the effects of different factors on the extraction rate of papaya seed oil,and confirm the optimum the technology conditions for extracting the papaya seed oil.[Method] With the papaya seed in the market-sold shine skin papaya as the tested material,the papaya seed oil was extracted by Soxhlet extraction method.The effects of the different extraction time,liquid-material ratio and extraction temperature on the extraction rate of the papaya seed oil were discussed and the optimum the conditions for extracting the papaya seed oil were confirmed through the single factor test and the orthogonal test.[Result] The single factor test showed that the optimum the extraction time for extracting the papaya seed oil was 9 h,the optimum liquid-material ratio was 8∶1 and the optimum extraction temperature was 45 ℃.The orthogonal experiments based on the single factor test indicated that,the optimum the conditions for extracting the papaya seed oil were as follows： the extraction time of 9 h,liquid-material ratio of 7∶1 and the extraction temperature of 48 ℃,under which,the oil yield of the papaya seed was 28.77%.[Conclusion] The study provided the reference basis for the comprehensive utilization and the development of the new products.
