Soy Epoxy Resin Based Beverage Can Coatings
A soybean oil derived epoxy beverage / food can coatings has been developed.
Epoxidized allyl soyate (EAS) coatings were assessed for their compatibility with food and beverages (beer and carbonated soft drinks). In addition mechanical, thermal, electrical properties and environmental stability of the epoxy composites were evaluated. Tests performed on the coatings are in the table below.

Blind Organoleptic evaluation of beer by expert panel
The test containers with ESA and commercial epoxy coated coupons were delivered to the Anheuser Busch Corp. The same were placed in sealed beer cans. The beer can were subjected to two week aging. At the end of the two week period beer from the containers was subjected to a blind organoleptic test
by a panel of experts assembled at the Anheuser-Busch facility in St. Louis. The panel rated the beer from each container for its taste, aroma, and other qualities. The panel ranked beer from each container on a 3-5 point system where a beer with a lower number is considered to possess higher quality. Beers with numerical values within 3.0-4.0 are considered acceptable. Beers from all containers fell within the acceptable range Results of the preliminary tests are given in Table – II
Beer in all test samples was found to be devoid of any off flavors or off taste. The panel gave all beer samples the same ranking. All were fully acceptable.
