Ultrasonic-assisted extraction of carotenoids using cottonseed oil: Optimization, physicochemical properties, and flavor studies

J Han, W Jia, Y Wan, X Sun, M Liang, C Wei… - Journal of food …, 2022 - Elsevier
Vegetable oils are ideal alternative solvents for extracting fat-soluble substances. Here,
response surface methodology, conventional analysis, and headspace-gas chromatography-
mass spectrometry were used to evaluate the effect of an extraction process on the
carotenoid yield, changes in physicochemical parameters, and flavor quality of cottonseed
oil (CSO). An optimal carotenoid recovery rate of 80.3% was obtained when the ultrasonic
power was 213 W, the extraction time was 36.0 min, and the temperature was 44.6℃ …
