The use of blueberry, defatted poppy seed and defatted grape seed powder has been proven to be effective in increasing the TPC and AOA of biscuits. This finding highlighted the efficacy of these natural antioxidant sources to improve the nutritional values of biscuits. In our study, the samples were produced in a commercial enterprise. Hence, these agents can be used in the industry easily.In general,all fortified biscuits had acceptable PV until the third month. However, sensory evaluation scores decreased rapidly because of the formation of aldehyde, ketones and FFA over time.Therefore,sensory acceptability of these products after 5 months was undesirable. Further investigations may explore the effects of different packaging systems to extend storage stability of fortificated biscuits.
