Effect of extraction conditions on carotenoids from Rhodotorula mucilaginosa

In this study, we investigated some conditions affecting the extraction of total carotenoids from R. mucilaginosa using environmentally friendly chemicals: cell disruption conditions with organic acids combined with ultrasound-assistant method, using ethanol and petroleum ether solvents to replace acetone in the process of extracting total carotenoids to obtain a benign product, easy to apply in food.
