摘要

Abstract

The oxidation of polyunsaturated fatty acids(PUFA)in emulsion with stirring and limited oxygen compensation was studied.A mathematical model of diffusion-oxidation was developed considering the mass transfer resistance of a gasliquid boundary

the resistance of the boundary layer from the emulsifier membrane

and the autocatalytictype autoxidation reaction of PUFA.The dynamic mass transfer coefficient of the emulsifier membrane

was introduced.The model was verified by comparing the predictions of the model with the experimental data.The results indicated that the model was in good agreement with the oxygen diffusion and linoleic acid oxidation in the emulsion

and showed good applicability in the prediction of the effect of the emulsifier type on the oxidation of PUFA in the emulsion.It indicated that the oxidation of PUFA in emulsions

with stirring and limited oxygen compensation from the atmosphere

was controlled mostly by mass transfer resistance from the emulsifier membrane.
