Citric Acid Cross-Linking Of Starch Films, Narendra Reddy, Yiqi Yang Jan 2009

Citric Acid Cross-Linking Of Starch Films, Narendra Reddy, Yiqi Yang

Faculty Publications - Textiles, Merchandising and Fashion Design

This paper shows that citric acid can cross-link starch and improve the tensile strength, thermal stability and decrease the dissolution of starch films in water and formic acid. The poor mechanical properties and water stability of starch have restricted its industrial applications. Although cross-linking is a common approach to improve the properties of starch products, current starch cross-linking methods are either expensive, toxic or do not impart the desired properties to the cross-linked materials. In this research, the possibility of cross-linking starch films using citric acid to improve their strength and stability was examined. Citric acid cross-linked starch films show ...


Rural Consumers’ Online Shopping For Food And Fiber Products As A Form Of Outshopping, Sharon J. Lennon, Young Ha, Kim K. P. Johnson, Cynthia R. Jasper, Mary Lynn Damhorst, Nancy Lyons Jan 2009

Rural Consumers’ Online Shopping For Food And Fiber Products As A Form Of Outshopping, Sharon J. Lennon, Young Ha, Kim K. P. Johnson, Cynthia R. Jasper, Mary Lynn Damhorst, Nancy Lyons

The purpose of the research was to longitudinally investigate rural consumers’ online shopping for food and fiber products as a function of satisfaction with local retailing and outshopping. Innovation diffusion theory was used to guide the research. Eight hundred seventy-nine rural consumers from 11 states completed surveys twice (in 2000 and 2003). Data were analyzed using structural equation modeling and analyses of variance. Dissatisfaction with local retailing in 2000 was a powerful driver of outshopping, beliefs about online shopping, and online shopping (both in 2000 and in 2003). Outshopping was positively related to online shopping at both points in time ...
