Drying Temperature Affect Secondary Structure of Soybean Protein-Isolate/Carboxymethyl Cellulose/Stearic Acid Composite Films

Abstract:

The effect of the drying temperature on the secondary structure of the soybean protein-isolate/carboxymethyl cellulose/stearic acid composite films was evaluated. The Fourier transform-infrared spectra showed that the stearic acid lose some characteristic absorptions. Hence, the stearic acid was well integrated with the other ingredients. The absorption band (1600~1700 cm^-1) of the composite film was deconvoluted into 9 peaks for the calculation of their secondary structure. The β-sheet content of the composite films dried at 90 oC was significant higher than that of the control. Hence, the composite films dried at 90 oC was more stable than the control.
