AI Technical Summary

Technical Problem

Existing oleogels are limited in variety and suffer from insufficient gel strength, poor stability, and limited functionality, making it difficult to meet the diverse needs of different fields. Furthermore, β-sitosterol, as a single-component oleogel, is prone to rapid phase separation and is difficult to form a stable oleogel structure.

Method used

β-sitosterol and propyl gallate were used as gelling agents and dispersed in the base oil by magnetic heating. After cooling, an oil gel was formed. The molar ratio and mass ratio were controlled, and the dispersion rate and temperature were kept within a specific range to avoid the hydrogenation process.

Benefits of technology

An oleogel with high oil retention and resistance to temperature changes was prepared, exhibiting good thixotropic recovery, oil retention, thermal stability, and freeze-thaw stability. This improved the oxidative stability and health benefits of oils, meeting the needs of different application scenarios.

Abstract

The invention discloses oil gel with high oil holding capacity and temperature change resistance and a preparation method thereof, and the preparation method comprises the following steps: dissolving a gelator in base material oil, dispersing under magnetic heating, and cooling to obtain the oil gel, wherein the gelator is prepared from beta-sitosterol and propyl gallate. According to the invention, beta-sitosterol and phenols are adopted as gelators, so that the variety of double gels is improved, and various properties of the oil gel are enhanced; the whole preparation process is carried out under a relatively mild temperature condition, and the performance of the final oil gel can be effectively regulated and controlled by controlling the dosage of the beta-sitosterol and the phenols, so that the requirements of different application scenes are met; the technical route does not involve a hydrogenation process, so that generation of trans-fatty acid is avoided; meanwhile, the heat of the grease is effectively reduced, and the oxidation stability and health benefits of the grease are improved.
