Interpretive Summary:

Technical Abstract: It has been known for decades that amylose will form inclusion complexes with various hydrophobic and hydrophilic compounds. Recently, soluble amylose inclusion complexes (AIC) have been formed using fatty acid or fatty amine salts. These AIC have been found to have value in a number of applications. It will be shown that they have superior emulsification properties than octenyl succinic anhydride starch, gum Arabic or sodium lauryl sulfate. The AIC can modify the surface properties of paper, cotton or wood, dramatically reducing the rate and amount of water which permeates the article. The fatty amine salt version of the AIC is an effective pesticide, killing pathogenic microbes as well as insects. Finally, polymers, such as polyvinyl alcohol or hydroxypropyl methyl cellulose, benefit from having up to 40% AIC incorporated in them. The ability to deliver value in so many different end-uses demonstrates the value of AICs which will result in providing a new high value end use for corn starch.
