This is done in order to establish the best concentration of the spice to be adopted in the chocolate drinks production. E. anomala seed powder was added into chocolate formulation in various concentrations [1%, 2%, 3%, 4%, as samples A, B, C, D with sample E as the control （no spice added）]. These samples were analyzed for difference quality attributes like： the proximate composition, minerals and chemical analysis, microbiological analysis, as well as the sensory evaluation using standard methods. The proximate composition showed the percentage moisture content ranging between 85.1 ±0.11 and 85.5± 0.10, ash content between 0.4 ± 0.00 and 0.5 ± 0.10, protein content between 1.0± 0.01 and 1.1 ± 0.11, fat content between 0.4 ± 0.1 land 0.5 ± 0.00 and carbohydrate content between 12.5 ±0.10 and 12.7 ±0.10. The minerals： 0.05 ±0.10 mg/kg, zinc： 0.01 4- 0.11 mg/kg, lead： 0.1 ± 0.10 mg/kg, and copper 0.1±0.1/l mg/kg, Mangeulese were obtained while cadmium was not detected at all. The chemical analysis gave between 5.03 ± 0. l t to 5.35 ±0.10, and pH 3.17 ± 0.10 to 3.67± 0.10, and total titratable acidity between 32.47 ± 0.10 to 32.50 ±0.10 tbr Brix. ttowever, sample C （3%） E. anomala spiced chocolate drink has the highest nutrients composition than all the other samples. All the samples have low microbial count, less than 3.5 ×10^3 load which is below the safe level of 1.0 ×10^3 but on the overall, sample C has the least value. Conclusively, smnple C, （chocolate spiced at 3% concentration） is established as the best sample nutritionally, microbiologically and on the overall acceptability.展开更多
