Summary: | The physicochemical properties and the antinutrient status of the
beverage, coke were evaluated to determine its suitability for
consumption and toxic levels in mammal. The mean levels of nitrates,
total nitrogen, chloride, ammonia, tannin, cyanogenic glycosides and
caffeine in the samples were (mg/l): 0.008 ± 0.001, 150.000 ±
3.446, 11.000 ± 0.686, 183.000 ± 3.019, 0.016 ±5.976,
0.020 ± 0.010 and 0.146 ± 0.002 respectively. The pH of the
samples gave a mean value of 3.500, while the mean metal concentrations
gave (mg/l) - 0.990 ± 0.099 (Mg); 38.030 ±0.050 (Na); 1.400
±0.114 (Fe); 0.650 ± 0.014 (Zn); 0.080 ± 0.005 (Mn);
4.720 ± 0.016 (K) and 10.120 ± 0.094 (Ca). Toxicological test
using whister albino Rats, shows that the beverage was relatively safe.
Generally, the results shows that the antinutrient status of the
beverage fell within the standards adopted by most countries.
Similarly, the other parameters fell within natural background level
although few fell above WHO specifications. |
