Abstract

Soy protein isolate (SPI) films exposed to formaldehyde vapor were prepared and observed for changes in selected properties of the films. The effect of different exposure times to formaldehyde on color, tensile strength (TS), percentage elongation at break. (E), water vapor permeability (WVP), and water solubility (WS) of SPI films was studied. SPI films bleached in color tint and became transparent following formaldehyde adsorption. TS of SPI films increased significantly (P<0.05) by adsorbing formaldehyde; while E decreased significantly. WVP and WS also decreased significantly (p<0.05) by adsorption of formaldehyde. Uniquely, for all properties, the majority of change in property values occurred within the first hour of exposure. Changes in properties of SPI film after exposure to formaldehyde treatment indicated development of cross-linking between formaldehyde and protein.
