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 µg g 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.
本研究旨在评估利用可再生农业工业副产品生产富含类胡萝卜素的微生物油（CRMO）的不同回收方法，以制备基于CRMO和巴西棕榈蜡（CW）的油凝胶。在油提取方法中，选择了布莱希和戴尔法，因为该系统能保持颜色稳定性。提取的CRMO总类胡萝卜素含量为41.1 μg/g，脂质含量为23.8%。对基于CRMO或橄榄油（对照体系）以及浓度为2.5%、5%、7.5%和10%的CW的油凝胶进行了表征，并强调了它们在食品体系中的潜在应用。本研究是最早描述基于CRMO的油凝胶生产的研究之一。其结果有助于其作为脂肪替代品的潜力。这种新型油凝胶可能满足全球减少食品中反式脂肪酸的需求，并作为生物活性生物化合物的保护体系。
