“…The use of alternative processes, such as liquid-liquid and supercritical extraction, has been proposed to retain high levels of antioxidant compounds in refined palm oil [5,6]. However, molecular distillation has shown better retention of carotenoids in palm oil, allowing the production of red palm oil (RPO) that retained 80 % of carotenoids and tocopherols [7,8].…”

This work aims to evaluate the use of an alternative process to deacidify palm oil using a strong anion‐exchange resin (Amberlyst A26 OH). The effects of the feed flow rate and the free fatty acids content in the feed stream were investigated by measuring breakthrough curves for bleached palm oil dissolved in n‐propanol. The resin had sufficient capacity and affinity to remove palmitic and oleic acids (98–99 %). The bed utilization efficiency can be optimized by choosing lower flow rates for oils with low levels of acidity, while higher flow rates can be used for oils with higher free fatty acids content. The ion‐exchange process can be used to obtain deacidified red palm oil, while preserving carotenoid and tocopherol/tocotrienol content. This alternative process has the advantage of occurring under mild conditions (44.0 ± 0.8 °C and atmospheric pressure) when compared with the conditions used in molecular distillation (150.0–170.0 °C and 2.7–3.3 Pa).

“…Aspen Plus ® has previously been used to model the SC fluid extraction (SCFE) of palm oil using SC CO 2 [22], where the SC extraction unit was modelled as a cascade of flash modules ("Flash2"). Benvenuti [23] also used a series of flash drums in Aspen Plus ® to model the SCFE of terpenes from lemon essential oil with SC CO 2 .…”

“…Deficiencies of these compounds in the human body may cause many diseases such as anemia, neurological dysfunction and myopathies. Degumming, bleaching and deodorization are the three major processes used during the physical refining method to remove undesirable components for other application 64 from crude palm oil. Different analytical extraction procedures such as pressurized liquid extraction 56 , Soxhlet extraction 65,56 and solvent extraction using mixtures of methanol and water in different proportions 50,52,66 , 60 % ethanol in water 54 were used for isolation of antioxidants from palm fruits and oils.…”

Supercritical fluid extraction of α-tocopherol and β-carotenoids from crude palm oil offers an excellent method over other existing conventional methods. Supercritical fluid extraction was developed in the early and mid-1980s to reduce the use of harmful organic solvent in the laboratory. The present paper reviews the applications of supercritical fluid extraction technology in extraction of palm oil using CO2 and R 134a fluids. Carbon dioxide is non-toxic, having low critical pressure (74 bar) and temperature (32 °C) which minimize the thermal degradation of product but it has a limited dissolving power for solutes of high polarity and high molecular weight in the supercritical state and it also requires higher pressure of upto 500 bar and this high pressure operation requires high operation cost and high capital cost. R134a is an alternative low pressure, non-reactive, non-flammable, non-toxic, non-ozone depleting and has comparable solvent properties as that of CO2. R-134a needs only its temperature or pressure to be controlled in order to control the conditions of extraction or product isolation. This allows simple control of the process.
