Effect of Surfactants on the Properties of Sunflower Wax Oleogels
In this paper,polyglycerol fatty acid ester-SW oleogel was prepared using polyglycerol-10 oleate(PG-10),polyglycerol polyricinoleate(PGPR)surfactant,and Sunflower wax(SW)as materials,and the effects of PG-10 and PGPR addition on the properties of oleogels were studied.The results showed that the addition of PG-10 and PGPR would affect the crystallization properties and oil-holding capacity of SW oleogels.With the increase of PG-10 addition,the number of olegel crystals decreased,and the oil-holding capacity decreased.However,the addition of PGPR at low concentrations(0.3%～1.0%)enhanced the oil-holding capacity of the oleogel structure,which may be related to its lower hydrophilic lipophilic balance(HLB).This study will help to provide a useful reference for the construction of multi-component lipid phases in food or cosmetics.
