Determination Of Nitrate, Nitrite, N-Nitrosamines, Malondialdehyde And PH Of Fruit Drinks Stored Under Sunlight Marketed In Umuahia, Abia State:- Emeh Chibuike G.
ABSTRACT
This study aimed at determining the
concentration of nitrite, nitrate, n-nitrosamine of some fruit juice sold in
Umuahia metropolis, Abia State. The nitrite, nitrate, n-nitrosamine, as well as
their by-product of metabolism, malondialdehyde (a deleterious by-product of
lipid peroxidation) and the pH value ofseven (7) branded fruit juice samples
were determined using chemical methods. Malondialdehyde and nitrite were
estimated spectrophotometrically, nitrate after reduction to nitrite with
cadmium column and N-nitrosamines after decomposition to nitrite using U.V
irradiation, while pH was determined using pH-meter. The results show that
nitrite ranged from 0.13 p/1- 1.10p/l, nitrate was non-detectable p/I- 1.10
p/1, while n-nitrosamine was nondetectable. Also, MDA value has range of
0.82p/l - 3.74 p/1 while the pH range was 2.80 p/1 - 3.30 p/1. From these
results, it can be safe to say that the fruit juices are relatively safe even
though chronic consumption should be discouraged.
