Abstract:
This study aimed to determine the variety of zobo that will give a desired colour and at the same time retaining most of the nutrient imbedded, after boiling for 10 min. The nutritional quality of non-alcoholic drink obtained from three varieties of zobo calyx (Hibiscus sabdariffa); dark red, bright red and wine subjected to the same preparation conditions were Investigated. Hundred grames of each of the samples were boiled separately in 4 L of water for 10 min to extract the juice into the water. The zobo drinks thus produced were analysed for their nutritional quality. It was observed that dark red zobo drink has the highest percentage of Vitamin C (7.5 mg g-1), calcium (4 ppm) and ash (15.5%) content, the bright red recorded a high value in only magnesium (13.25 ppm) and the wine however, recorded the highest value in sodium (50.67 ppm), potassium (235 ppm), iron (1.17 ppm). The pH was noted to be high in all the three varieties i.e., 2.53. 2.50 and 2.67 for dark red, bright red and wine, respectively. The sensory evaluation also showed that the dark red zobo drink has the highest acceptability. It was therefore, concluded that the three varieties had their peculiar nutritional benefits therefore the choice depends on the producer and consumer; however, from the sensory evaluation the dark red was more preferred.
