Abstract
This study aimed at evaluating the effects of ginger inclusion on the bioactive, antioxidant, antihyperglycemic, and nutritional characteristics of groundnut-based snack (Kulikuli). The groundnut paste used in the preparation of Kulikuli was partially substituted with different levels (2.5%, 5%, and 10%) of ginger powder. The results showed that the bioactive, antioxidant, and inhibitory properties of ginger-substituted Kulikuli were significantly (p < .05) enhanced as the level of ginger increases. Also, carbohydrate and fiber contents of ginger-substituted Kulikuli were significantly (p < .05) increased. There was significant reduction (p < .05) in estimated glycemic index and in vitro starch digestibility which was proportional to the level of ginger in the Kulikuli. The sensory scores of the ginger-substituted Kulikuli revealed that they were well accepted. Therefore, ginger can serve as a functional ingredient in the making of Kulikuli, a groundnut-based snack for people suffering from oxidant-related diseases. With the increasing concern about the safety of orthodox hyperglycemic drugs, there is need to develop diet-based therapy to manage diabetes mellitus. Because of this, ginger (Zingiber officinale), a spice with vast nutritional and pharmacological importance was substituted with groundnut to produce a functional groundnut-based snacks (Kulikuli). The supplemented Kulikuli exhibited improved bioactive, antioxidant, glycemic, and antihyperglycemic properties. Therefore, the Kulikuli supplemented with ginger can serve as a functional snack for people suffering from diabetes mellitus and other oxidant-related diseases.
