“…Figure shows that at a constant temperature, increasing the pressure increased the amount of β‐carotene. This result is consistent with the results of Tai and Kim (). Increasing the pressure increased the solvating power, and more diffusion in the plant matrix led to an increased amount of β‐carotene.…”

The objectives of this research were to determine the suitable conditions and mathematical equations to predict the efficiency of aril oil extraction from gac (Momordica cochinchinensis Spreng), including the amounts of β‐carotene, lycopene, iodine value, acidity, and peroxide in the oil, using supercritical carbon dioxide. The experiments were planned using central composite design (CCD) for two factors, temperature (31, 35, 45, 55, and 60C) and pressure (130, 150, 200, 250, and 271 bar), and the optimal conditions for oil extraction were 50–60C and 200–250 bar, which resulted in 80–100% extraction efficiency, 30–50 mg β‐carotene per 100 g, 10–20 mg lycopene per 100 g of oil, 60–80% iodine values, and an acidity of 0–4 mg potassium hydroxide. In comparing the oil extraction efficiency and the amounts of β‐carotene, lycopene, iodine value, and acidity, there was a discrepancy (%D) of <10% between the experimental values and the values predicted from a mathematical model at 55C and 220 bar, indicating that the mathematical model was able to predict the extraction efficiency and the amounts of β‐carotene, lycopene, iodine value, and acidity very well. Moreover, when the pressure was increased, the extraction efficiency also increased, and when the temperature was increased at a pressure of 150–200 bar, the extraction efficiency decreased. These increases in temperature and pressure resulted in greater amounts of β‐carotene and lycopene in the aril oil from Momordica cochinchinensis Spreng. Practical Applications The extraction of aril oil from Momordica cochinchinensis Spreng using supercritical fluid was studied. The optimal conditions for the extraction of aril oil from Momordica cochinchinensis Spreng using a supercritical fluid were 52–55C and 200–250 bar, which resulted in an extraction efficiency of 80–100%, 30–50 mg β‐carotene per 100 g, 10–20 mg lycopene per 100 g, 60–80% iodine values, and an acidity of 0–4 mg potassium hydroxide per gram. Supercritical fluid extraction resulted in a better extraction efficiency of oil with higher amounts and better chemical properties of carotenoids compared to using a screw press.

“…The RSM-COM optimization study carried out in this work was centered in the experimental data provided by Tai et al [7], who measured SFE curves under different P,T and Q CO 2 /W biomass conditions. The Q CO 2 /W biomass is the ratio of CO 2 mass flow rate to biomass weight, which is equivalent to a weight hourly space velocity (WHSV); it will henceforth be called specific CO 2 flow rate.…”

“…: +351 234 401549; fax: +351 234 370084. Gac (Momordica cochinchinensis Spreng) is a traditional fruit from south Asia, mainly from Vietnam, and its aril not only exhibits an interesting amount of oil (up to 44.4 wt.% [7]), but also a remarkable abundance of carotenoids like lycopene and ␤-carotene [8]. The latter are present in amounts five times greater than in tomatoes, and ten times greater than in carrots, respectively [9].…”

“…Due to the bioactive features of carotenoids, such as anti-carcinogenic, and antioxidant effects [8,10], the enhancement of their presence in the gac oil has triggered a remarkable interest in the scientific community. So far gac oil is usually obtained either by mechanical pressing or solid-liquid extraction using organic solvents, but the SFE has been recently tested and provided auspicious results for both a productive and green extraction process [7].…”

Macauba kernel oil (MKO) was extracted using supercritical CO 2 and compressed propane as the solvent. The influence of temperature (313-353 K for CO 2 and 303-333 K for propane) and pressure (18-22 MPa for CO 2 and 8-12 MPa for propane) on oil yield was investigated, and the results were compared with conventional extraction. A characterization of oil and defatted meal was performed. Temperature and pressure, in the evaluated range, influenced oil yield with the use of CO 2 . For propane, the oil yield was not influenced by the experimental conditions. In the evaluated experimental range, the use of propane and CO 2 provided 100 % and $93 % oil yield compared to conventional extraction, respectively. MKO showed a predominance of saturated fatty acids, among which lauric acid was the major constituent. CO 2 presented greater efficiency in the removal of phytosteroids and tocopherols from the macauba kernel, however, the oil extracted with propane presented longer oxidative stability. Defatted meals presented modified physico-chemical composition and potentiated technological characteristics due to oil removal.
