Demonstrating performance is a key element in designing and


providing a new product solution to a customer. In Figure 1, the improved efficacy of VERDILOX in chicken fat was demonstrated by storing chicken fat treated with 1,000 ppm and 3,000 ppm of either Naturox™ Premium Liquid or VERDILOX GT Liquid at 60o


C for 26


days to mimic fat storage in a truck and in a holding tank. The stability was then measured by monitoring the peroxide values (PV) weekly. The data clearly shows the improvement in performance for VERDILOX GT Liquid versus a tocopherol based antioxidant, such as Naturox Premium Liquid. For example, at day 26 the PV of the 1,000 ppm Verdilox treatment remained below 5 meq/kg fat, while the Naturox treatment was above a PV of 20 meq/kg fat. This demonstrates that the Verdilox was effective in controlling peroxide values in bulk fat when stored at elevated temperatures.

After 6 weeks of storage, the Chicken and Rice Feline diet showed


a significant efficacy improvement for the Verdilox combination versus the Naturox combination. After 6 weeks of accelerated storage at 37o


the Verdilox PV was 1.1 meq/kg sample versus 2.2 meq/kg sample. In addition, after 7 weeks of storage the Lamb and Rice Canine diet


showed a significant efficacy improvement for the Verdilox combination versus the Naturox combination. After the 7 weeks of accelerated storage at 37 o


C, the Verdilox PV was 1.7 meq/kg sample versus 2.2


meq/kg sample. Combining vertically integrated plant selection, crop improvement,


and manufacturing competencies with existing product innovation and application research has led to this novel antioxidant product line that meets customers’ needs for a sustainable, antioxidant supply.


The most critical testing was validating performance in a model diet


that would show the activity in pet food. In Figures 2 & 3 the improved efficacy of VERDILOX in extruded pet food diets was demonstrated. Both of these diets contained either 1,000 ppm of Verdilox GT Dry or 1,000 ppm Naturox Plus Dry in the dry mix prior to extrusion. The chicken fat coating was then either treated with 4,000 ppm Verdilox GT Liquid or 4,000 ppm Naturox Premium Liquid.
