ABSTRACT
Herbal teas are receiving increasing attention from consumers because of their perceived nutritional and health benefits. Current study evaluated the formulation of guava leaf teas supplemented with Moringa oleifera and dry ginger powder as supporting and activating herbs respectively. The formulated herbal combinations were packed as dip tea bags designated M1 and M2. Nutritional composition, functional properties and anti-nutritional factors were investigated using standard analytical methods of Association of Official Analytical chemist. Data was analyzed by ANOVA and results expressed as mean and standard deviation. Result of proximate composition indicates that ash and moisture content were within Association of Southeast Asian Nations (ASEAN) recommended standard. The result also revealed that the formulations contain appreciable amount of all essential amino acids. Functional properties indicate that bulk density range from (0.39 - 0.36 g/cm3 ), swelling index (2.8 - 3.7 ml/g), reconstitution index (6.6 - 6.8 g/ml), water absorption capacity (83.52 - 89.65 ml/g) and pH (6.11- 6.22). Selected micro nutrient estimated suggested that the composite blends are good sources of minerals like Zn, Ca and Fe which are of public health importance. Based on the results of this study, it can be concluded that guava leaf tea supplemented with moringa and ginger are good reservoir of macro and micro-nutrients with potential nutritional health benefits
