Abstract In order to stabilize the whole wheat flour and extend its shelf life, microwave was employed to heat the wheat pineapple polly pocket bran to inactivate the lipase in this paper.The effects of microwave heating of wheat bran on the lipase activities, gluten properties, dough properties and storage stability of the stabilized whole wheat flour, and the quality of steamed bread made of stabilized whole wheat flour were investigated.Furthermore, molecular docking was sled shelf applied to interpret the mechanism.The results showed that microwave can reduce lipase activity, maintain the quality of whole wheat flour dough and steamed bread, and retard rancidity.The molecular docking results displayed that the conformation of the amino acids chains near the lipase catalytic center changed, which made the substrate difficult to enter the catalytic center and prevented the hydrolysis of the fat substrate.
