✦ Synopsis

Nutmeg (Myristica fragrans Houttuyn) was extracted with liquid carbon dioxide at 90 bar and 23.0°C. The seed is rich in essential and fatty oils, with myristicin and myristic acid being the characteristic compounds in each group respectively. Coextraction of essential oil and fatty oil was observed, and extraction curves for each were obtained. Chromatographic analyses of essential and fatty oils were performed.

The effects of particle size and solvent flow rate in extraction yield and velocity were studied. It was demonstrated that extraction yield can be greatly improved by a reduction in particle size. The extraction rate could be enhanced during the second period of extraction via an increase in solvent flow rate.

Dioxins and dibenzofurans are suspected to be quite toxic. They are fat soluble, and therefore, accumulate in fat-rich tissues (e.g., fish liver) and in products like milk. They have been detected in a large amount of food raw materials. Therefore it is urgent to find ways to purify such materials.
