background of turmeric oil extraction
Ginger or turmeric oil is an important natural product extracted from the root and stem of turmeric (Curcuma longa L.), containing active ingredients such as gingerols, gingerols, and borneol. It is widely used in the fields of food spices, pigments, and pharmaceuticals. The extraction process directly affects the yield, composition, and purity of the product, so choosing the appropriate method is crucial for industrial production
The extraction process of turmeric oil extraction mainly includes steam distillation, organic solvent extraction, ultrasonic assisted turmeric oil extraction, supercritical CO ₂ extraction, and composite processes combining new technologies. Among them, the supercritical CO ₂ turmeric oil extraction method performs the best in yield and quality, while continuous countercurrent ultrasonic extraction achieves continuous production of ginger butter and curcumin, improves automation level and extraction efficiency
Key conclusion of turmeric oil extraction
If pursuing high-quality, residue free, and industrializable turmeric oil extraction production, supercritical CO ₂ turmeric oil extraction method is the preferred choice; If limited by equipment costs, ultrasound assisted solvent extraction turmeric oil combined with subsequent purification steps can be considered. Meanwhile, optimizing process parameters using orthogonal or response surface methodology can significantly improve efficiency
