“…Um dos grandes problemas do fruto é a baixa conservação pós-colheita, pois se trata de um produto altamente perecível que possui rápida perda de água nos seus tecidos em função da alta taxa respiratória (Mirahmadi et al, 2011), além de ser suscetível à incidência de fungos que acarretam perdas consideráveis, tanto nutritivas quanto econô-micas (Malgarim et al, 2006;Reis et al, 2008).…”

Postharvest conservation of strawberry fruits at different storage conditionsStrawberry is a product appreciated by consumers due to the organoleptic characteristics. However, strawberry fruits are highly perishable after harvest, so alternative measures to prolong the shelf life of fruits are necessary. The objective of this experiment was to evaluate the fruit postharvest conservation of strawberry cultivars under different storage conditions. Strawberry fruits of eight cultivars (Festival, Campinas, Toyonoka, Dover, Oso Grande, Camarosa, Diamante and Aromas) were grown at "Mape Frutas" farm, in Datas municipality, Minas Gerais State, Brazil. Strawberry fruits were stored at cold storage (2.34±0.78°C; 89.93±4.14% RH) and environmental conditions (17.43±2.68°C; 74.11±10.44%). The experimental design was randomized blocks in a factorial arrangement with eight strawberry cultivars and five storage times, with three replications. Fruits appearance, disease incidence, total soluble solids, titratable acidity, vitamin C and firmness were evaluated every 3 days, until 12 days. At room condition, strawberry fruit could be stored for only three days. Fruits kept in cold chamber kept quality until 12 days. Cv. Festival had the best postharvest shelf life in both storage conditions and cvs. Toyonoka and Campinas showed higher incidence of diseases and less fruit firmness when compared to the other cultivars.

“…Accordingly, Malgarim et al (2006a) reported mean initial content of 7.35 °Brix in fruits of cv. Camarosa, with variations in content values having no relation with the treatments or storage periods.…”

“…Increased acidity can also be related to the release of galacturonic acids, which accelerate fruit ripening by the action of the enzymes pectinmethylesterase and polygalacturonase (Arriola et al, 1980). Malgarim et al (2006a) reported TTA of 0.6 g citric acid.100 g -1 of pulp on fresh strawberries cv. Camarosa; as discussed by the authors, this lower acidity may be due to different conditions of cultivation as well as soil and climate characteristics.…”

RESUMO Conservação pós-colheita de morangos recobertos com fécula de mandioca e quitosanaO morango é classificado como fruto não climáterico, mas apresenta taxa respiratória pós-colheita elevada, o que o leva a uma rápida deterioração em temperatura ambiente. Este trabalho teve por objetivo avaliar a aplicação de revestimentos biodegradáveis na conservação pós-colheita de morangos orgânicos, cv. Camarosa, acondicionados em embalagens plásticas e armazenados a 10 °C. Os tratamentos foram: a) controle, b) fécula de mandioca 2%; c) quitosana 1% e; d) fécula de mandioca 2% + quitosana 1 %. Foram avaliadas as características físicas e químicas dos frutos, aos três, seis e nove dias de armazenamento, e realizadas análises microbiológicas e sensoriais, ao final do armazenamento. Os tratamentos alteraram positivamente a qualidade pós-colheita dos morangos orgânicos. O revestimento que mais se destacou foi fécula de mandioca mais quitosana, apresentando valor inferior a 6% de perda de massa nos frutos, menor quantidade de leveduras e de micro-organismos psicrotrófilos e melhor aparência na análise sensorial.Palavras-chave: Fragaria ananassa Duch., revestimentos biodegradáveis, qualidade sensorial. Post-harvest conservation of organic strawberries coated with cassava starch and chitosanThe strawberry is as non-climacteric fruit, but has a high post-harvest respiration rate, which leads to a rapid deterioration at room temperature. This study aimed to evaluate the application of biodegradable coating on postharvest conservation of organic strawberries, cv. Camarosa, packed in plastic hinged boxes and stored at 10 °C. The treatments consisted of: a) control; b) 2% cassava starch; c) 1% chitosan; and d) 2% cassava starch + 1% chitosan. Physical and chemical characteristics of fruits were evaluated at 3, 6 and 9 days of storage, and microbiological and sensory analyses were carried out at the end of the storage period. The treatments influenced positively the post-harvest quality of organic strawberries. The coating cassava starch + chitosan provided the best results, with less than 6% of loss in fruit mass, lower counts of yeast and psychrophilic microorganisms and the best appearance according to the sensory analysis.

“…The mass loss showed a linear relationship tendency with the storage time in both treatments and fruits. When the strawberries loose 6% of their weight in the trees they are no longer marketable (MALGARIM et al 2006). In this aspect it was checked that strawberries cover with bacterial cellulose were efficient in the reduction of the weight loss, with average values of 5.7%…”

The consumer by fresh food such as fruits has increased in the last decades and the minimally processed has come to attend this demand. The focus of this paper is to evaluate the application of celluloses biofilm in the conservation of minimally processed fruits. It was followed a (2 x 5) factorial design, with two treatments (with and without cellulose) and five periods of storage (0, 48, 96, 144 and 192h
