DuPont Nutrition & Health introduces GUARDIAN® TOCO 30P, a highly effective and label-friendly antioxidant from naturally sourced mixed tocopherols in a powder form.

Manufacturers of cereal and granola brands now have a convenient, easy-to-use antioxidant protection product when compared to liquid tocopherols. The powder format can help ease manufacturing concerns such as homogenous distribution, handling, labor-intensive cleanup and application equipment costs and limitations.

“GUARDIAN® TOCO 30P simplifies the process by incorporating antioxidants into the dry mix and eliminates the need for additional equipment and cleanup,” says Luping Ning, group manager, Bars/Confections/Snacks/Cereals. “This new antioxidant solution in a cost-effective powder form helps to reduce expenses while improving productivity.”

Shelf-life studies validate the antioxidant activity. In accelerated shelf-life studies of commercial cereal products, GUARDIAN® TOCO 30P at 1000 ppm was found to significantly inhibit oxidation of the cereal as indicated by reduced level of hexanal, while sensory evaluation of the cereals correlated well with hexanal levels. In a separate accelerated shelf-life study, GUARDIAN® TOCO 30P was incorporated into the dry mix of extruded oat and corn cereal. Sensory testing at 12 weeks of accelerated storage showed that both 1200 ppm and 1500 ppm levels significantly reduced “cardboard” and “painty” flavor attributes.

“Tocopherols enable a consumer-friendly ingredient declaration compared to synthetic antioxidants,” added Ning. “Now cereal and granola brands have a solution that contributes to a positive eating experience by maintaining cereal freshness with greater consumer acceptance, all while contributing to the bottom line.”
