“…In the case of high pressure processing as reported by Jung and Mahfuz (2009), the use of high pressure induced protein aggregation yet it was further hydrolyzed by protease, thus facilitated oil removal. On the other hand, Shan, Jiang, and Li (2011) reported that ultrasound generated cavitations which accelerated the leaching out of cellular components including oil.…”

“…On the other hand, Shan, Jiang, and Li (2011) reported that ultrasound generated cavitations which accelerated the leaching out of cellular components including oil. The use of extrusion prior to AEE has been extensively studied by Jung and Mahfuz (2009), and Wu et al (2009. According to these authors, protein aggregates are formed during extrusion but these entrap or interact with the oil.…”

“…Extruders provide enough pressure and temperature on seeds to deactivate enzymes (Gerpen et al, 2002). Jung and Mahfuz (2009) used a dry extruder with high temperature for extraction of oil and protein. They found that increased extruder pressure increased the protein solubility in soybean oil.…”

“…Mass transferring is another critical factor for AEP, the raptured cell wall by extruding or flaking could increase oil extraction to around 71%. However, that is still quite lower than hexane extraction (Wu et al, 2009, Jung & Mahfuz, 2009). …”

Aqueous oil extraction is a process which replace organic solvent, hexane is most used in solvent extraction, with water. Comparing to typical solvent extraction and expelling processes, the aqueous extraction has higher oil yield (over 80%) than expelling process and that is exempt the issues resulted from chemical loading and remaining. The enzyme was used to improve the breakdown of cell and release free oil. The enzyme assisted aqueous extraction process (EAEP) includes dehulling, flaking, extraction and demulsification processes. SuperPro Designer was used to conduct the techno-economic analysis (TEA) of the extraction process. The total capital investment, operation cost and profits were evaluated. For EAEP extraction, that uses insolubility of water and oil, hence that could extract oil and protein simultaneously which decreases the operation cost especially on oil purification process and increases the profits from main product, soybean oil, and coproduct mainly protein in skim. Additionally, the free chemical loading and enzyme recycling also decrease material costs. Though the facility costs might increase due to extraction and demulsification processing unit, the value-added coproduct and high free oil yield are potential to have economic feasibility in pilot scale production.
