Recognizing Challenges And Opportunities In The Quest To End Hunger, Jennifer Williams Zwagerman
Texas A&M Law Review
As an attorney and professor that does not focus on intellectual property law, I was a bit apprehensive about providing a keynote address for a Symposium focusing on “Agriculture, Intellectual Property, and Feeding the World in the 21st Century.” As I thought about this topic, knowing that there were other speakers who would focus more on the IP issues and technical aspects of various topics, I kept coming back to the importance of technology as we worktowards the goal of feeding the world, and the many ways in which innovation plays a role in meeting that goal. It also brought …

In this study, caffeic and ferulic acids were used to test the effect on acrylamide formation and elimination in model reaction systems. In asparagine/glucose reaction system, addition of caffeic and ferulic acid at the concentration of 25 mmol/L and 250 mmol/L inhibited acrylamide formation. However, they increased acrylamide formation below 2.5 mmol/L. It was found that both of phenolic acids increased acrylamide elimination when ferulic acid or caffeic acid were heated with acrylamide, but the effect is not obvious, so effect of caffeic acid and ferulic acid influenced on acrylamide content in Maillard reaction system mainly influence on acrylamide formation …

This study aimed at the effects of purple sweet potato powder (PSP) with different amounts (namely null, 5%, 10%,15% and 20%) on the rheological properties and pasting properties of dough tested by farinograph, extensograph, and rapid viscosity analyzer. The results showed that addition of PSP significantly influenced the properties of a dough. With the increase of PSP, the rheological properties and gelatinization properties of the dough were improved, which means PSP could lessen the gluten thews and inhibit the gelatinization and expansion process of wheat dough. However, the PSP could rise the bibulous rates, and reduce retrogradation value, which could …
