the aim of this study was to examine the adverse effects of zinc nanoparticles on hematological indices of trout and investigate the improvement of these indices after vitamin c treatments. this study assesses the protective role of vitamin c in fish exposed to zno nps. two concentrations of zno-nps (40 and 80 mg l-1) and two doses of vitamin c (400 and 800 mg per kg of feed) were used to treat...

Consumption of vegetables and fruits is associated with a reduced risk of stroke, but it is unclear whether their protective effects are due to antioxidant vitamins or folate and metabolically related B vitamins. The purpose of the study was to test the hypothesis that intake of fruits and vegetables, which are major sources of antioxidant and vitamin B complex vitamins, reduces the risk of str...

Antioxidants are substances which, when present in low concentrations, compared with that of an oxidisable substrate, significantly delay or prevent oxidation of the substrate (Halliwell & Gutteridge 1989). The most abundant antioxidants in fruits and vegetables are polyphenols and vitamins, especially vitamin C. Vitamins A, B and E and carotenoids are present to lesser extent in some fruits. T...

This study provides a versatile validated method to determine the total vitamin C content, as the sum of the contents of L-ascorbic acid (L-AA) and dehydroascorbic acid (DHAA), in several fruits and vegetables and its degradability with storage time. Seven horticultural crops from two different origins were analyzed using an ultra-high-performance liquid chromatographic-photodiode array (UHPLC-...

In the present study, effects of edible coatings using sodium alginate (SA) and sodium alginate in combination with ascorbic acid (AA) on the shelf-life extension of strawberries at 4±1°C was studied. A factorial experiment was performed based on a randomized complete block design with four replications. The treatments included control (distilled water), SA (1%, 2%, 3% w/v), SA in combination w...
