Abstract
Two new Bulgarian selected hybrid sweet cherry cultivar candidates (El.17-90 ‘Asparuh’ and El.17-37 ‘Tzvetina’ – Fruit Growing Institute, Plovdiv, Bulgaria) and one standard cultivar (Bing) were chitosan treated and stored in refrigerator at 4°C for 21 days, up to the endpoint of the experimental shelf-life time. Chitosan-Ca-lactate (multicomponent) and Chitosan-alginate (bi-layer) edible coating treatments were applicate in these experiments. The used coating formulas are bio compatibles, non-toxics and have antimicrobial activities. The sample series (five replicates with thirty fruits from each cultivar and each treatment, and a control) were inspected weekly based on the appearance. The healthy and intact fruits were tested for physical (visual sorting, weight loss and texture of the intact fruits), physico-chemical (refractometrical dry content, antioxidant activity, pH of the pulp), and microbiological properties (total number of microorganisms, E. coli, fungi and yeasts). At the beginning of the storage, the control samples (not treated) showed better appearance and harder texture than the treated samples, because they had to suffer less manipulations. Later they lost these preferences, but the Chitosan-alginate treat was able to preserve the fruits in a better state. This study shows that the edible coating is a promising method to preserve the nutrition value of fresh fruits. The application is possible in preparation of ready-to-eat fruit salads or in fruit decoration of confectionery products.

An author should not normally publish manuscripts describing essentially the same research in multiple journals or publication venues. Such redundant publication is generally considered to constitute unethical publishing behavior, and if discovered may result in a manuscript under consideration being rejected, or a published article being retracted.
Authors of manuscripts reporting on original research should present an accurate account of the work performed, accompanied by an objective discussion of its significance. Underlying data should be represented accurately in the manuscript. The manuscript should contain sufficient detail and references to permit others to replicate the work. The fabrication of results and the making of fraudulent or knowingly inaccurate statements constitute unethical behavior and may be cause for rejection or retraction of a manuscript or published article.
