sensitivity of tomato fruit to low temperature and chilling injury limits the storage, handling and marketability of the fruit. as a recommended postharvest treatment, effects of hot water treatment (hwt) on reducing chilling injury and quality traits, variation of tomato fruits during storage life were investigated. tomato fruits were harvested at mature green stage. they were treated by hot w...

The effect of pressure treatments of 100 and 200 MPa (10 and 20 min) and of thermal blanching at 70 C, 80 C and 98 C (1 and 2.5 min), on sweet green and red bell peppers was compared. Pressure treated peppers showed a lower reduction on soluble protein and ascorbic acid contents. Red peppers presented even an increased content of ascorbic acid (15–20%), compared to the untreated peppers. Peroxi...

The aim of this research was to study the effect of paclobutrazol pretreatment on the changes of antioxidative enzymes and antioxidants in the flooding-stressed sweetpotato Ipomoea batatas (L.) Lam. ‘Tainung 57’ was grown in plastic boxes in a screenhouse and maintained in optimal water conditions for 45 days followed by PBZ treatments (0 and 0.5 mg/plant) for 1 day. Then flooding was induced b...

It has been suggested that ascorbic acid is necessary for the transparency and metabolism of the crystalline lens (see Bellows, 1944). Primarily, this is based on well-authenticated observations of a loss of ascorbic acid from animal and human lenses undergoing spontaneous opacification. In experimentally induced cataract, however, loss of ascorbic acid does not always occur; thus, naphthalene ...

Studies were conducted to evaluate the blood levels of ascorbic acid, dehydroascorbic acid, glutathione, and histamine in patients with gastric carcinoma, tuberculous enteritis and non-specific ulcerative colitis. Leucocyte ascorbic acid, urinary excretion of total ascorbic acid and ascorbic acid saturation test were also carried out in order to assess the ascorbic acid status of these patients...

ABSTRACT. The present work was aimed to determine the contents of ascorbic acid and antioxidant activity eight types common fruits commercially available in Addis Ababa, Ethiopia using iodometric titration UV-Vis spectrophotometric methods, respectively. were found range 15.41 mg/100 g grapes 78.01 papaya. highest papaya (89.41) lowest water melon (31.28) mg equivalent per 100 edible part fruit...

Introduction: ascorbic acid is a water-soluble vitamin solved in water that acts as a helper of some the enzymes in the reactions of energy metabolism. Thus, the study aims to investigate the use of supplemental ascorbic acid on the aerobic and anaerobic capacity of the children.Methodology: Participants of this quasi-experimental study were 18 children in Esfahan who were randomly selected and...

An attempt was made to unravel further the mechanism by which high dietary concentrations of ascorbic acid influence copper metabolism. The addition of ascorbic acid to the diet of rats caused about a twofold increase in plasma ascorbate concentrations and reduced group mean plasma and tissue concentrations of Cu. The effect of 10 g ascorbic acid/kg diet was greater than that of 1 g/kg. Ascorbi...

Background: Liposomes constitute a promising drug delivery vehicle, and are believed to improve drugs’ effectiveness. This study was aimed to compare antihypertensive and vascular modifying activities of liposomal and non-liposomal forms of ascorbic acid. Methods: Forty-nine male Sprague-Dawley rats were randomly divided into seven groups (n=7): A sham vehicle-receiving (Sham-veh), hypert...

Objective(s): The aim of this study was to determine the protective role of ascorbic acid on apoptosis and proliferation of spermatogonia and primary spermatocyte cells after malathion administration as an organophosphate pesticide in rat testis.Materials and Methods: Thirty male Wistar rats were randomly divided into five groups of 6 ra...
