doi:10.16178/j.issn.0528-9017.20230175

Abstract

Abstract:

Chinese torreya seed oil is rich in nutrients and has high health care functions. The purpose of this study was to explore the most suitable extraction process of sciadonic acid from Chinese torreya seed oil. The urea embedding method was used to optimize the extraction and preparation process of sciadonic acid from Chinese torreya seed oil by response surface method on the basis of single factor test. The results showed that the optimal experimental conditions for urea-embedded extraction of sciadonic acid from Chinese torreya seed oil were as follows: binding time 2.07 h, urea 33 g, binding temperature 68.93 ℃, and the optimal extraction amount of sciadonic acid from Chinese torreya seed oil was 4.53 g.

Key words: Chinese torreya seed oil, sciadonic acid, urea embedding, response surface method, extraction
