Determination Of Nitrate, Nitrite, Nitrrosamine, PH And Malondialdehyde (MDA) Of Fruit Drinks Exposed To Sunlight:- Nnochiri Odinaka W
ABSTRACT
This study aimed al determining some
physicochemical properties of some fruit juice sold in Umuahia metropolis, Abia
State. The nitrite, nitrate, n-nitrosaminc, as well as their by-product of
metabolism, malondialdehyde (a deleterious by-product of lipid peroxidation)
and the pH content of seven (7) branded fruit juice samples were determined
using chemicalmethods. 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 — 1.10 pg/ml, nitrate was -0.28 — 1.10 pg/ml while n-nitrosaminc was - 0.08
--0.39 pg/ml. Also, MDA value has range of 0.82 - 3.74 pg/ml while the pH range
was 2.80 — 3.30. From these results, it can be safe to say that the fruit juice
are relatively safe even though chronic consumption should be discourage.
