A granola-type, omega-3-rich breakfast cereal prototype was developed using ground flaxseed as the principal source of linolenic acid (1.8% w/w). Other ingredients included rolled oats, yellow sugar, honey, sliced almonds, and canola oil. The focus of the research investigation was to apply and study the addition of an antioxidant (AO) and the use of Modified Atmosphere Packaging (MAP) on shelf-life extension of the enriched cereal. Granola samples, both with and without AO (300ppm of 70% mixed tocopherols), were packaged in air, and under the two atmospheres achieved by nitrogen flushing (MA 1) and an oxygen scavenger (MA2). Samples were stored at either 21 or 35°C. / Shelf-life was terminated when products reached a thiobarbituric acid (TBA) value of 4.0 mg malonaldehyde/kg corresponding to a sensory score of 5 (on a hedonic scale of 10).
