摘要

The functional beverage market has recently increased due to the health benefits in addition to their nutritional and thirst-quenching functions. Tigernut is an economic crop with reported health benefits. This study evaluates the antioxidative potential of processed tigernut extracts fortified with baobab fruit pulp powder. The ferric reducing antioxidant potential, 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid), and l,l-diphenyl-2-picrylhydrazyl were used to determine the antioxidant capacity, while the Folin-Ciocalteu method was used to measure the total phenolic content of the beverages. The inclusion of baobab fruit significantly (P<0.05) increased the total phenolic content by 18% (from 31.06 to 36.83 mg gallic acid equivalent/100 mL)and the flavonoid content by 15'-20%, while the vitamin C content peaked at 39.6 mg/100 mL. There was a significant correlation between the phenolic and vitamin C contents. Overall, the antioxidant potentials were elevated with the inclusion of baobab powder. All the beverages included in this study are good sources of Ca, P, and K; the contents of Ca, P, and K in the roasted tuber extracts with baobab peaked at 210.91, 8.70, and 93.35 mug/mL, respectively. However, the K: Na ratio was greater than 5:1. Although, baobab increased the acidity of the beverages, it did not significantly diminish the consumer acceptability, with the values ranging from 7.62 to 8.40 on a 9-point Hedonic scale. The beverages have potential for use as natural antioxidants and could be recommended for consumers with diets deficient in Ca and K, particularly in food insecure communities. They could also be used as a replacement for sugar-sweetened carbonated beverages.
