Effect of environmental factors [air and UV-C irradiation] on some fresh fruit juices

Abstract: The present study was carried out to evaluate the effect of environmental factors (air and UV-C irradiation) on various common fruits juices (lemon, orange, papaya and grape). Total phenolics, total ascorbic acid (AA) content and antioxidant capability were determined in atmospheric air oxidation on fresh fruit juices, and the effect of UV-C irradiation on AA was investigated in both fresh fruit juices and commercial AA using RP-HPLC. The total phenolics content was found to be 92.46 ± 1.5, 41.53 ± 2.1, 138.56… Show more

“…A similar study was done with a sample of orange juice, but in this case, no significant degradation of vitamin C was observed during a working day if the sample was kept refrigerated. Differences in stability could be due to the acidity of the orange juice and also the presence of complexing agents such as citrate and flavonoids, which bind to metal ions that could otherwise catalyse the oxidative degradation of vitamin C (Rameshkumar et al ., ).…”

“…Gradient elution program followed; Solvent A and B was 0-10% (5 min), 10-15% (5 min), 15-20% (5 min), 20-30% (5 min), 30-40% (5 min); Flow rate was 1 mL/min and maximum pump pressure 4000 psi was maintained. Polyphenolics were identified at wavelength of 280 nm [17]. Compounds were identified and confirmed by comparing its tR and λ max compared with commercial standard.…”
