Extraction of Aril Oil from Gac Using Supercritical Carbon Dioxide

What is it about?

The extraction of aril oil from Momordica cochinchinensis Spreng using supercritical fluid was studied. The optimal conditions for the extraction of aril oil from Momordica cochinchinensis Spreng using a supercritical fluid were 52–55C and 200–250 bar, which resulted in an extraction efficiency of 80–100%, 30–50 mg bcarotene per 100 g, 10–20 mg lycopene per 100 g, 60–80% iodine values, and an acidity of 0–4 mg potassium hydroxide per gram. Supercritical fluid extraction resulted in a better extraction efficiency of oil with higher amounts and better chemical properties of carotenoids compared to using a screw press.
