Free Fatty Acids Separation From Malaysian High Free Fatty Acid Crude Palm Oil Using Molecular Distillation

Abstract: Molecular distillation is industrially useful in the purification of highly oxidative oils and fats, and their derivatives. Free Fatty Acids (FFAs) were isolated from high free fatty acid crude palm oil (HFFA-CPO) using molecular distillation. The isolation conditions were set-up with feeder flow rate of 2.3 g/min, wipers speed of 350 rpm, evaporator temperature ranging from 150 °C to 265 °C and pressure at 10 torr respectively. The results showed that the yield of crude palm oil after separation (CPO AS ) was… Show more

“…The evaporation temperature for Camelina sativa oil (as a mixture of FFA, TAG, DAG, MAG, and other components) was selected at 150 • by many experimental trials when the first distillate was collected (evaporation degree between 1% and 10%) at pressure 0.1 Pa. This temperature, much lower than reported in literature [11][12][13][14][15], allowed us to reduce the heat consumption required by the evaporator, even if a high vacuum must be ensured. The wiper rolling speed and feed flowrates were chosen according to the limits of the equipment.…”

“…Due to these major drawbacks, alternatives methods need to be used on an industrial scale; to improve oil quality, the solvent traces in purified oils can be replaced using environmentally friendly solvents, such as CO 2 , under supercritical conditions [10]. Degradation of thermolabile compounds from oils can be avoided by using methods such as molecular distillation or advanced vacuum distillation [11][12][13][14][15][16]. Some researchers showed their interest in improving deacidification process using molecular distillation.…”

“…FFA content is usually around 3-4% in CPO (Kumar and Krishna, 2014). The acceptable limit of FFA content for food application is 5% (Bahadi et al, 2016), and CPO with more than 5% FFA is suitable for other applications such as in the manufacture of biodiesel (Hayyan et al, 2013). Other components in CPO that can generate rancidity and deteriorates of the oil are trace metals, moisture and non-acylglycerol impurities (Nagendran et al, 2000).…”

“…The chemical modification to be used is either esterification or transesterification reaction depending on the free fatty acid (FFA) present in the NEI oil. The percentage of FFA content is an important specification that affects the quality of palm oil in the storage, production and marketing stages [9]. This will enable NEI to be used in the distribution transformer [10].…”
