“…Likewise, in soybean oil extraction, organic solvents such as hexane increase the probability of reverse micelle formation due to the surfactant nature of Pl (Hou et al, 2020). These micelles can reach MW of 20 000 Da or more (Boynueğri et al, 2017), which simplifies the separation process by membrane technology.…”

“…In this study, the membrane composition of 15% PVDF, 75% N-methyl-2-pyrrolidinone and 10% ethylene glycol showed excellent performance with satisfactory flux (47.5 L h -1 m -2 ) and 94% micelle rejection. Boynueğri et al (2017) studied the tubular PVDF membrane performance with an MWCO of 20 000 Da for degumming crude soybean oil using a reverse osmosis/ultrafiltration module. According to the results, it was possible to reject 86.11% of phospholipids, and an average flux of 17.04 L h -1 m -2 at 40°C and 2 MPa pressure was realised.…”

Palm oil is one of the most widely commercialised vegetable oils globally. This oil contains important phytonutrients, such as carotenoids (provitamin A), tocopherols and tocotrienols (vitamin E). These phytonutrients are thermally degraded and removed from crude palm oil (CPO) through bleaching techniques in the refinement process. This article focuses on using membrane technology as a green alternative to recover these compounds, specifically, the use of nanofiltration as a potential mechanism for recovering edible oil phytonutrients from palm oil. Furthermore, due to the few studies related to this topic, the review also highlights microfiltration and ultrafiltration uses in other crude oils (CO) for degumming and deacidification refining processes for phospholipids (Pl) and free fatty acids (FFA) removal. Finally, an overview of the biological functions of palm oil phytonutrients in health and their applications in the food industry is presented.

“…Membran teknolojisi, geleneksel ayırma yöntemlerine göre birçok avantaja sahiptir. Bu avantajlar, membranla fosfolipidlerin ayırılmasının oda sıcaklığında gerçekleşebilmesi ve bu sayede sıcaklığa duyarlı ürünler için daha kaliteli ürün elde edilmesi, diğer işlemlerle kombine olarak uygulanabilmesi, sürekli veya kesikli sisteme uygun olması, kimyasal madde kullanılmaması ve düşük enerji tüketimi gibi sıralanabilir [33], [34].…”

Bitkisel kaynaklı tohum ve meyvelerden elde edilen ham yağların rafinasyonu, yağın yapısındaki istenmeyen bileşenlerin uzaklaştırılması ya da miktarlarının kabul edilebilir düzeye düşürülebilmesi amacıyla uygulanmaktadır. Rafinasyon işlemi sırasında istenmeyen maddeler yağdan uzaklaştırılırken ya da miktarları kabul edilebilir düzeye düşürülürken; yağda bulunan biyoaktif özellikteki bileşenler (tokoferoller, fenolik maddeler, steroller, skualen vb.) nitel ve nicel olarak kayba uğramakta, konjugasyon ve trans izomerizasyon reaksiyonları meydana gelmekte, bir proses bulaşanı olan 3-MCPD oluşabilmektedir. Rafinasyon kademelerindeki biyoaktif madde kaybını azaltmak ve/veya istenmeyen bileşiklerin oluşmasını engellemek için sistem içi, yenilikçi, teknik çözümlerin geliştirilmesi gerekmektedir. Bu amaçla; daha düşük sıcaklıkta gerçekleştirilebilen, işlem süresinin kısaltıldığı, daha az kimyasal madde kullanılan, ultrases destekli rafinasyon gibi yenilikçi ve kimyasal reaksiyonları hızlandırıcı etkisi olduğu bilinen tekniklerin uygulandığı rafinasyon akışlarının geliştirilmesi gerekmektedir. Bu derlemede; ultrases destekli degumming, asitlik giderme ve renk açma konusunda yapılan bilimsel çalışmalar detaylı olarak ele alınarak özetlenmiştir.The refining of crude oils obtained from plant origin seeds and fruits is applied in order to remove the undesirable components in the oil or to reduce the amount to an acceptable level. While the unwanted substances are removed from the oil during the refining process or the quantities are reduced to an acceptable level; bioactive compounds (tocopherols, phenolic substances, sterols, squalene, etc.) in the oil are lost qualitatively and quantitatively, conjugation and trans isomerization reactions and process contaminants such as 3-MCPD occur. Intrasystem, innovative, technical solutions need to be developed to reduce the loss of bioactive compounds in the refining stages and/or to prevent the formation of undesirable compounds. For this purpose; refining flows, which can be carried out at a lower temperature, shorter processing time, using less chemicals, are supported by innovative techniques such as ultrasound-assisted refining and accelerating chemical reactions, need to be developed. In this review; the scientific studies on ultrasound assisted degumming, neutralisation and bleaching steps are summarized in detail.
