Pure Rosemary Oil Extraction Process

1. Supercritical CO2 fluid extraction: In a 1L extraction kettle, place 160.0g of evenly crushed and sieved rosemary powder. Design three factors and three levels of extraction time, extraction pressure, and extraction temperature, using the oil yield as an indicator. Conduct orthogonal experiments and repeat the process 2 times, taking the arithmetic mean of the results. The optimal process conditions are: extraction pressure of 20.0MPa, extraction temperature of 40.0°C, and extraction time of 4.0h, resulting in an oil yield of 4.40%.

2. Steam distillation: In a 500mL round-bottomed flask, place 20.0g of evenly crushed and sieved rosemary powder. Design three factors of material particle size, liquid-to-material ratio, and extraction time, using the oil yield as an indicator. Conduct a horizontal orthogonal experiment according to the volatile oil determination method in the appendix. The optimal process conditions are: material particle size of 0.20mm, liquid-to-material ratio (v/w) of 4:1, and extraction time of 4.0h, resulting in an oil yield of 1.40%.
