| Abstract: | The Sloanea hemsleyana seed protein was used as a raw material to prepare Sloanea hemsleyana seed protein in edible fihns. The influences of various process parameters on the performances of Sloanea hemsleyana seed protein in edible films were studied. The opt mized conditions were obtained by single factor test and orthogonal test, which was mass fraction of Sloanea hemsleyana seed protein in 6% , glycerin dosage 30% （g/g protein）, pH 9. 0, reaction temperature 80℃, and reaction time 20 rain. Under the optimum cinditions, the tensile strength of Sloanea hemsleyana seed protein in edible films reached 14. 53MPa, elongation was 56. 17% , transparency was 72. 17% , and water vapor transmission was 18. 12g . mm . （m2 .h . kPa） -1 |
