Resumo: | Potatoes of the variety “Monalisa” were minimally processed like slices and submitted to different treatments, employed to decrease the enzymatic browning and growth of microorganisms. These treatments consisted on pure cellulose films (FP) or incorporated with active compounds (2% of citric acid (AC), 0,5% of L-cysteine Hydrochloride Monohydrate (CIS), 7% of sorbic acid (AS) and film incorporated with all of them (MIS)) which were intercalated to sliced potatoes. For control, potatoes were conditioned without film. All of the samples were conditioned in expanded polystyrene trays, wrapped up in PVC film and stored 8ºC ± 2ºC by nine days. Every three days, they were evaluated for color, pH, water activity (Aw) and microbiological quality (growth of total Coliformes and to 45ºC, Molds and yeasts, Psychrotrophics, Bacillus cereus and Staphylococcus positive coagulase). The treatments didn’t differ significantly (p>0,05) for most of the evaluated parameters, except for the color difference, that presented significant difference to the 10% of probability. In conclusion, the active films can minimize the enzymatic browning of vegetables. |

Utilizaram-se filmes celulósicos incorporados com aditivos (2% de ácido cítrico (AC), 0,5% de monocloridrato de L-cisteína (CIS), 7% de ácido sórbico (AS) e mistura dos compostos mencionados (MIS)) ou sem a incorporação destes (Filme FP), que foram intercalados às batatas fatiadas. Como controle, foram utilizadas batatas mantidas sem filme intercalado (SF). Todas as amostras foram acondicionadas em bandejas de poliestireno expandido, envoltas em filme de PVC e armazenadas por 9 dias a 8ºC ± 2ºC. A cada três dias, as amostras de batatas foram avaliadas quanto à cor, pH, atividade de água (Aa) e qualidade microbiológica (contagem de Coliformes totais e a 45ºC, Fungos filamentosos e leveduras, Psicrotróficos, Bacillus cereus e Staphylococcus coagulase positiva). Observou-se que para os mesmos tempos de estocagem, os tratamentos não diferiram significativamente (p>0,05) para a maioria dos parâmetros avaliados, com exceção da diferença de cor, onde diferiram significativamente aos 10% de probabilidade. Conclui-se que os filmes ativos anti escurecimento têm potencial de serem usados em vegetais que apresentam deterioração por escurecimento enzimático.
