Ultrasound is one of the emerging and novel techniques in oil extraction process. In this study, the oil was extracted from kapok seed using ultrasonic acoustic cavitation and conventional extraction techniques. The present study results found that Ultrasonic Cavitation-Assisted Extraction (UCAE) produced 92.29% of oil recovery with a shorter extraction time of 10 min compared to solvent extraction (5.7 h) and Soxhlet (8 h). The fatty acid composition of oils revealed that the linoleic acid (33.86%–37.64%), palmitic acid (21.79%–25.42%), and oleic acid (23.39%–25.01%) are predominantly present in oils. The oil obtained from UCAE, contains slightly higher composition of oleic, linoleic, malvalic and sterculic acids compared to other methods. The total energy consumption taking into account all possible utilisation was measured and found that the energy consumption of CUAE method is 80 folds lower than soxhlet and 50 folds lesser than SE.

Industrial Relevance

This research paper provides KSO production with the high quality, shorter time as well as the energy utilised by ultrasound process seems to be better. This research helps to develop a new and economical method of kapok seed oil production.

超声空化是一种从木棉籽中提取油脂的新兴节能技术

超声波是石油开采过程中新兴的新兴技术之一。在这项研究中，使用超声波空化和常规提取技术从木棉籽中提取了油。本研究结果发现，与溶剂萃取（5.7 h）和索氏萃取（8 h）相比，超声空化辅助萃取（UCAE）产生了92.29％的油采收率，且萃取时间缩短了10分钟。油中的脂肪酸组成表明，油中主要存在亚油酸（33.86％–37.64％），棕榈酸（21.79％–25.42％）和油酸（23.39％–25.01％）。与其他方法相比，从UCAE获得的油包含的油酸，亚油酸，苹果酸和硬脂酸组成略高。

产业相关性

该研究论文为KSO生产提供了高质量，更短的时间以及超声过程所利用的能量似乎更好。这项研究有助于开发一种新的经济的木棉籽油生产方法。
