Abstract

SummaryThe effects of chitosan coatings (1.0% and 2.0% w/v) in controlling the decay of strawberries and raspberries and maintaining their quality were investigated. A chitosan coating significantly reduced the decay of berries stored at 13°C and induced a significant increase of chitinase and β-l,3-glucanase activities of the berries as compared with the controls. Chitosan coating proved almost as effective as the fungicide TBZ in controlling the decay of berries stored at 13°C caused by Botrytis cinerea and Rhizopus sp. Chitosan coating had beneficial effects on firmness, titratable acidity, vitamin C content, and anthocyanin content of strawberries and raspberries stored at 4°C.

8 of 18 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
