摘　　要： The experimental results showed that sucrose methyl fumarate(SMF)of 5.5 degree of esterification (DE) possessed better surface activity,which HLB value was 6.8,CMC 0.75mmol/L and surface tension 28.5mN/m of 2mmol/L mole concentration.The emulsion activity of SMF was superior to sucrose stearate and had excellent emulsion stability when concentration was more than its CMC.The foam activity and stability of SMF and Span-80 was inferior to sucrose stearate.The characters of SMF recombination with other surfactant and the application in food industry need further research.
