摘要：
This study aimed to evaluate different methods of recovery of carotenoid-rich microbial oil (CRMO) produced by Rhodotorula mucilaginosa in renewable agro-industrial by-products to achieve oleogels based on CRMO and carnauba wax (CW). Among the oil extraction methods, Bligh and Dyer was selected since this system kept color stability. Extracted CRMO showed 41.1 mu g g-1 of total carotenoid and lipid content of 23.8%. Oleogels based on CRMO or olive oil (control system) and CW at concentrations of 2.5, 5, 7.5, and 10% were characterized and their potential application to food systems was highlighted. This study is one of the first to describe production of oleogel based on CRMO. Its results contribute to its potential as a fat replacer. This novel oleogel may meet worldwide demands to reduce trans fatty acids in foods and act as a protective system of bioactive biocompounds.
