The results
revealed that the starch fraction of 0.5 was a critical point for the conversion of the protein matrix to
starch matrix and conversion of the gel from elastic to weak. Moreover, the protein-starch synergistic
effect on the storage modulus was strongest at fractions of 0.5 and 0.6, due to the formation of a
semi-interpenetrating network, with more amylose from the melted starch granules interpenetrated
with the protein molecules, and the absorption of water by the starch granules to concentrate the protein
matrix. Additionally, no covalent interaction between the protein and starch occurred with increasing
starch fraction, thus having no significant influence on the protein secondary structure
