  • How is rice bran oil extracted?
  • Rice bran (RB) oil extraction was performed by applying renewable solvents like ethanol and ethyl acetate. To assess the interaction of these solvents with the oil, the UNIFAC model was chosen to determine the infinite dilution activity coefficient. Soxhlet extraction was utilized to determine the maximum possible yield.
  • Which solvent is used for rice bran oil extraction?
  • The extraction yield was higher when using ethyl acetate as the solvent. Rice bran (RB) oil extraction was performed by applying renewable solvents like ethanol and ethyl acetate. To assess the interaction of these solvents with the oil, the UNIFAC model was chosen to determine the infinite dilution activity coefficient.
  • How much rice bran is produced in 2022?
  • According to the International Rice Research Institute, the amount of rice bran produced corresponds to about 5–10% of the rice to be polished, reaching a world production of around 25–50 million cubic meters between 2022 and 2023.
  • Does ethyl acetate reduce LN in rice bran oil extraction?
  • Rice bran oil extraction was conducted using ethanol and ethyl acetate as solvents. RSM was used to evaluate the effects of temperature and solvent/rice bran ratio. Ethyl acetate was found to have a lower ln (IDAC) compared to ethanol. The mass transfer kinetic model accurately predicted the experimental data.
  • Why is RB extracted oil a low yield?
  • This may result from the fact that the RB extracted oil acts itself as a co-solvent in the process, causing saturation to exist around the biomass particles, which causes the lack of improvement in the yield with the increase in the amount of solvent added ( Gasparetto et al., 2023c ). Fig. 3.
  • What are the independent variables of RB oil extraction?
  • The independent variables are x 1 and x 2, which represent the temperature (K) and the solvent/RB ratio, respectively. The coded intervals of − 1 and 1 correspond to temperature values of 298.15 K and 328.15 K and solvent/RB ratio values of 4.00 and 8.00. The dependent variable of the process is the RB oil extraction efficiency.
