Abstract: Research preparation process of edible films of Loquat core starch, Yuhang County, Zhejiang Province Tangxi loquat cores as raw materials; On the single-factor test of starch, sodium alginate, glycerol and carrageenan, through the central composite experimental design and the response surface Methodology (RSM) analysis and optimization for preparation process. Glycerol and starch have a significant impact on the elongation at break, tensile strength and oil permeability of the film, carrageenan has a significant influence on elongation at break of the film , sodium alginate have a significant impact on oil permeability of the film. The optimum preparation process was determined as: starch 68 g·L-1, sodium alginate 7 g·L-1, glycerol 11.25 mL·L-1 and carrageenan 1.25 g·L-1.in the condition ，the starch of tensile strength, elongation at break, Swelling and through oil and other performance indicators are optimum．In this study, the preparation process can ensure the good mechanical properties of edible films of loquat core starch，and easy to scale-up.
