Sample A value for vitamin C is 72.2mg/L while of sample B is 96.9mh/L. in terms of pH sample A is 5.0 and that of sample B is 5.5. According to WHO, (2009), the daily recommended vitamin C content that ought to be taken is 65 – 90mg while orange pH should be between 4 – 6; both sample (A and B) conform to WHO, (2009) value in terms of vitamin C and pH. Thus, the importance of vitamin C in humans should not be overemphasized.
