CO₂ supercritical extraction and microencapsulation of oleoresins from rosehip fruits for getting powders with multiple applications.

ABSTRACT: The supercritical fluids extraction (SFE) was used to extract the oleoresins from rosehip, followed by an in-depth phytochemical analysis and the development of two design-customized powders for different food and pharmaceutical applications. The SFE experiments allowed obtaining an oleoresins extraction yield of 11.85%. Two fractions were separated (S40 and S45), with significantly different phytochemical profile (p < 0.05), highlighting the efficiency of extraction of fatty acids in S40 extract, whereas the extraction of polyphenols, phytosterols, carotenoids and polyphenols was favored in S45 extract. The phytochemical profile revealed that the linoleic acid (C18:2) and α-linolenic acid (C18:3) represented approximatively 82% and 58% from the total fatty acid content in S40 and S45, res
