Abstract:
Emphasis has significantly been placed on the production of functional foods and the utilization of indigenous food crops in the management of some diet-related non-communicable diseases. This study included African walnut in the production of a cookie snack, and the effect of the inclusion on its nutritional, antioxidant and sensory quality was assessed. The inclusion of cooked grated walnut in the cookie caused a significant increase in crude protein (2.67%), fat (2.57%), fiber 91.17%), TPC (2.97 mgGAE/g db), DPPH (1.44 µmol TE/gdb) except for total starch, in-vitro protein, and starch digestibility. This resulted in nutrient-dense cookies, rich in antioxidants with a low estimated glycemic index, suitable for people with non-communicable pathophysiological conditions. Considering the sensory scores, walnut enriched cookies were accepted by the consumers comparably with the wheat flour cookies. Hence, walnut enriched cookies may be adequate in promoting health-related functions, while satisfying consumer’s urge for snacking.
