Tóm tắt
Garlic is a familiar spice in all households and in medicine. It is also known for its potent antioxidant and anti-cancer properties. This study determined the optimal combination of operating parameters for the hydrodistillation of Ly Son garlic essential oil. The effects of distillation time, water-to-material ratio, soaking time in NaCl solution, and NaCl concentration on the yield of essential oil extraction were investigated. The results established the optimal extraction conditions as follows: distillation time of 2.5 hours, soaking time of 1 hour, NaCl concentration of 2%, and a water-to-material ratio of 1:7. Under these conditions, the maximum yield obtained was 3%. Ly Son garlic exhibited the highest antioxidant capacity, while Phan Rang garlic showed the lowest.
