  • How to extract garlic oil?
  • The most commonly used methods for extracting garlic oil are steam hydrodistillation and hot solvent extraction. Water temperature, distillation time, and particle size are factors that influence the efficiency of hydrodistillation extraction .‌
  • What is the yield of garlic oil extraction?
  • The yield of garlic oil extraction expressed as the volume of oil after evaporation of the solvent was dependent on the extraction method used, with the highest result of 7.00% for supercritical fluid extraction (SCF). The oil obtained with the SCF method exhibited high viscosity, which facilitated encapsulation.‌
  • What temperature should garlic ethanol be extracted?
  • Dehariya et al. analyzed the effect of 2, 3, and 4 h garlic ethanol extraction with the Soxhlet method at temperatures of 50, 60, and 70 °C on the efficiency and antioxidant properties . The highest yield, i.e., 16.55%, was obtained after 4 h of extraction at 50 °C.‌
  • What are the parameters ensuring the best quality of garlic oil extraction?
  • According to the results obtained by Chen et al. , parameters ensuring the best quality of garlic oil extraction with the use of solvents are as follows: temperature 45 °C, time 42 min, solvent to raw material ratio 4:1, number of extractions 4 .‌
  • How is garlic oil prepared?
  • Medicinally used garlic oil is mostly prepared by hydrodistillation of raw garlic homogenate. The garlic oil is insoluble in water, therefore can be separated or extracted afterwards. Garlic oil consists of the diallyl, allyl methyl and dimethyl mono to hexa sulfides , , .‌
  • What is the quality of garlic essential oil?
  • Garlic Essential Oil Quality Depending on the Extraction Method Garlic oils are obtained by steam distillation of garlic cloves using n-hexane or petroleum ether, among other methods . The amount of oil in garlic cloves is in the range of 0.20–0.50%, and DADS and DATS are the bioactive compounds in the oil.
