Abstract
Abstract In this study, the effect of different homogenization stirring speeds (10,000 rpm, 12,000 rpm, 14,000 rpm, 16,000 rpm, 18,000 rpm and 20,000 rpm) on mechanical and water barrier properties of gallic acid treated zein-oleic acid composite films was investigated. In addition, the effect of low and high homogenization speed on film microstructure with respect to speeds at 10,000 rpm and 20,000 rpm was also investigated. Results showed that homogenization stirring speed significantly (p −2 h −1 kPa −1 ) registered in gallic acid treated sample homogenized at 10,000 rpm. Results further revealed that WVP increased with increasing homogenization stirring speed especially in gallic acid treated zein films suggesting that the film matrix was being weakened as homogenization became more intense. Films produced by low homogenization speeds were characterized by smooth and homogeneous film microstructures as opposed to heterogeneous and coarse microstructures exhibited by films produced using high homogenization speeds.
