Antioxidant constituents in some sweet pepper (Capsicum annuum L.) genotypes during maturity
TL;DR: The nutritional significance of consuming sweet peppers at the red maturity stage because of enhanced functional properties is proposed and overall genotype Flamingo and Anupam represent superior genotypes for both nutrition and germplasm improvement.

Effect of ultrasound treatment on fruit decay and quality maintenance in strawberry after harvest
TL;DR: In this article, the effects of ultrasound treatment on fruit decay and physiological quality of strawberry fruit were investigated, and the results showed that 40 kHz ultrasonic treatment significantly reduced decay incidence and numbers of microorganism.
Journal ArticleDOI
Antioxidant activity in some red sweet pepper cultivars
TL;DR: In this article, the authors compared 10 red sweet peppers grown over two consecutive years with regard to ascorbic acid, total reducing content, β-carotene, total antioxidant activity and free radical scavenging activity.

Solubilisation of tomato fruit pectins by ascorbate: A possible non-enzymic mechanism of fruit softening
Jo C Dumville,Stephen C. Fry +1 more
TL;DR: Testing the hypothesis that endogenous ascorbate, released into the apoplast by membrane permeabilisation early in fruit ripening, could promote the solubilisation and depolymerisation of polysaccharides, and thus contribute to fruit softening suggests non-enzymic mechanisms of fruitSoftening should be considered alongside the probable roles of hydrolases, xyloglucan endotransglucosylases and expansins.

A method for the determination of small quantities of ascorbic acid and dehydroascorbic acid in turbid and colored solutions in the presence of other reducing substances
TL;DR: Although the titration procedure has been very useful and quite satisfactory for most plant tissue and some animal tissues, there are several limitations and hazards involved in its general use.

Flavonoids: some physiological and nutritional considerations.
R.E. Hughes,H.K. Wilson +1 more
TL;DR: Flavonoids by inhibiting ascorbic acid breakdown and thereby reducing the mutagenic potential of ageing tissues could be of some significance in both the ageing process and the incidence of disease.

Stability of ascorbic acid in extracts of iris leaves.
V. H. Booth,B. J. Constable +1 more
TL;DR: It is shown that leaves of the iris have a higher content of ascorbic acid than any of those mentioned above and also that they have an exceptionally low oxidase activity.
Journal ArticleDOI
Tissue ascorbic acid and a liver dehydroascorbatase in guinea-pigs.
TL;DR: There was no evidence that changes in dehydroascorbatase activity could account for the modified tissue ascorbic acid concentrations associated with ageing or with the ingestion of fluoride, flavonoids or anthocyanin material.
