Abstract

This research was undertaken with a view to develop antioxidant rich high protein biscuits with health promoting benefits. The flour used for this purpose was procured from Manildra Group of Pty Ltd Company. In order to enhance the antioxidant properties of the biscuits, four traditionally well-known underutilized plants with several health benefits have been chosen. These are Moringa leaves, Gotu kola leaves, Schisandra berries, and Goji berries that are known to exhibit antioxidant, antidiabetic, anticancer, anti-inflammatory, immunostimulatory, and cardioprotective properties. The dried form of leaves and berries were used in this research. The research was designed to prepare biscuit samples with different substitutions of the selected plant's material. Sample 1 was substituted with 1% of all the four plants in equal proportion Sample 2 was substituted with 2% of all the four plants in equal proportion; Sample 3 was substituted with 3% of all the four plants in equal proportion; Sample 4 was substituted with 4% of all the four plants in equal proportion; Sample 5 was substituted with 1% of Moringa and Gotu kola leaves in equal proportion; and Sample 6 was substituted with 1% of Schisandra and Goji berries in equal proportion. A control sample without any plant material was also prepared as a reference. Amongst the different biscuit samples developed in this research, sample 4 had the highest proportion of plant's material.Nutritional and chemical analysis of the four plants used in this study revealed that all of them exhibited highly significant radical scavenging activities that are superior to many well-known anticancer traditional herbs.
