Effects of lipid concomitants on the stability of rapeseed oil nanoemulsions
Objective:Clarifying the effects of lipid co-passengers on the stability of rapeseed oil emulsions and prepare high-stability nano-emulsions.Methods:The endogenous lipidassociated compounds of rapeseed oil were subjected to column chromatography filtration,followed by various concentration gradient re-addition.High-pressure microfluidization was utilized to prepare nanoemulsions,which were subsequently characterized.The influence of lipid associated compound content on the stability of rapeseed oil emulsions was also investigated.Results:The preparation of rapeseed oil nanoemulsions reached optimal conditions when the a-tocopherol content was 292 mg/kg,rapeseed polyphenols content was 32 mg/kg,β-sitosterol content was 6 712 mg/kg,and β-carotene content was 31 mg/kg.The average particle size of the resulting rapeseed oil nanoemulsion was(182.4±2.056)nm,indicating good stability.Conclusion:Lipid associated compounds significantly affect the stability of emulsions.
