The strawberry cultivars Arosa, Clery, Miss, Raurica, Queen Elisa, Diamante and Madeleine grown in Slovenia were harvested at the commercially maturity stage and the content of total ascorbic acid and dehydroascorbic acid (DHA) was determined. Ascorbic acid (AA) was measured by using high-performance liquid chromatography and photodiode array detector. The total AA content of cultivars ranged f...

The effect of calcium chloride brine treatment on firmness and retention of phytochemicals in pastuerized yellow banana peppers was studied. Shear force values declined during processing and storage, but CaCl(2) treatment resulted in greater firmness retention. Processing reduced ascorbic acid content by 63%, and after 124 days, <10% of ascorbic acid remained. Quercetin and luteolin contents de...

UV-B radiation induced alterations in the contents of photosynthetic pigments, antioxidants (phenolics and ascorbic acid) and chlorophyll fluorescence in two tropical variants of Trichosanthes cucumerina L. – Cucurbitaceae. The Green (Variant A) and Light Green (Variant B) variants of T. cucumerina, which had earlier been shown to differ in their total phenolics contents, were used for the stud...

to determine the effects of pre-harvest salicylic acid (sa) treatments on postharvest life and quality of apricot fruits, four different concentrations (one, 1.5, three and 4.5 mm) were applied six days before harvesting of apricot fruits cv. ‘shamlou’. fruits harvested at commercial maturity stage and stored at 2ºc with 90 percent rh on the same day for a period of three weeks. the fruit was e...

In order to enhance bioactive functionalities of ginseng, an acid impregnation processing was applied as a pre-treatment in producing red ginseng. Acid impregnation studies were conducted, and acids (ascorbic, malic, and citric acid) were selected. The optimal concentration of each acid was investigated in this study in terms of ginsenoside contents. The most concerned ginsenoside, Rg3 was incr...

The present paper deals with the influence of starvation on fish which has great ability to adapt in starvation stress. In the present investigation, the effect of prolonged food deprivation on ascorbic acid contents of gonadal tissues has been observed in both the sexes of Clarias batrachus. The level of ascorbic acid content was found relatively higher in males than in females. The testes sho...

Neuroblastoma cells accumulate ascorbic acid and iron. It was hypothesized that these features could be exploited for sensitizing neuroblastoma cells for therapy in combination with reactive oxygen intermediates. In the present study the effects of 6-hydroxydopamine (6-OHDA) and H2O2 on metabolic parameters critical for cell survival were investigated in cells with low and high ferritin content...

Storage of potatoes is very important because fresh potatoes are available only for a few months in a year. Thus, any treatment such as irradiation that controls sprout growth and extends shelf life of potatoes could be beneficial. In this study, potato sprout inhibition and tuber quality after treatment with various levels of Gamma Irradiation (0, 50, 100 and 150 Gy) on different dates (10, 30...

The aim of this study was to prepare the freeze dried powder noni (Morinda citrifolia) pulp and determine contents bioactive antioxidant capacity. Seed, peel, lyophilized were characterized in terms physico-chemical, carotenoids, chlorophyll, sugars, ascorbic acid, phenolics, flavonoids antioxidants contents. Phenolic compounds determined by LC-MS. showed high levels phenolics (7486.38 µg GAE/g...
