Resumo: | The objective of this study was to evaluate the efficacy of the sanitization process using aqueous ozone and chlorination in reducing the microbial load on strawberries subjected to minimal processing. Strawberries were selected, washed in tap water, and sanitized using the following treatments: T1) Immersion in aqueous ozone at 0.2 mg/L for 5 min; T2) Immersion in aqueous ozone at 0.5 mg/L for 5 min; T3) Immersion in aqueous ozone at 1.0 mg/L for 5 min; T4) Chlorination; T5) Control; or T6) Strawberries without sanitization (natural). After sanitization, the fruits were processed, drained, packaged, and stored under refrigeration at 5ºC ± 1ºC for 6 days. Microbiological analyses for coliforms at 35ºC (MPN/g) and counts of filamentous fungi and yeasts (CFU/g) were performed on the day of processing. Microbiological enumeration of coagulase-positive staphylococci, coliforms at 45ºC (MPN/g), and detection of Salmonella spp. were performed on the day of processing and again after 6 days of storage. The microbial count of total coliforms was observed only in T6. Treatments with aqueous ozone were more effective than treatment with chlorine in removing filamentous fungi and yeasts. Contamination by Salmonella spp., Escherichia coli, and coliforms at 45ºC was not observed in the analyzed samples. |

Morangos foram selecionados, lavados em água corrente e submetidos aos tratamentos: T1) Imersão em água ozonizada a 0,2 mg L-1 por 5 min; T2) Imersão em água ozonizada a 0,5 mg L-1 por 5 min; T3) Imersão em água ozonizada a 1,0 mg L-1 por 5 min; T4) Cloração; T5) Controle; T6) Morangos in natura. Posteriormente, os frutos foram processados, drenados, embalados e armazenados em câmara de refrigeração a 5ºC ± 1ºC, por seis dias. As análises microbiológicas para Coliformes a 35ºC (NMP g-1) e Contagem de Fungos Filamentosos e Leveduras (UFC g-1) foram realizadas no dia do processamento. Enquanto que as análises microbiológicas de Enumeração de estafilococos coagulase positiva, Coliformes a 45ºC (NMP g-1), e detecção de Salmonella sp. foram realizadas no dia do processamento e após 6 dias de armazenamento. A carga microbiana de Coliformes totais foi constatada apenas em T6. Os tratamentos com a água ozonizada foram mais eficientes do que o cloro na remoção de fungos filamentosos e Leveduras. A contaminação por Salmonella sp., E. coli, e coliformes 45ºC não foram observada em nenhuma das avaliações.Instituto Nacional de Controle de Qualidade em Saúde2015-01-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion"Peer-reviewed article""Artículo revisado por pares""Artigo avaliado pelos pares"application/pdfhttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/article/view/43710.3395/2317-269x.00437Health Surveillance under Debate: Society, Science & Technology ; Vol. 3 No. 1 (2015): February; 61-66Vigilancia en Salud en Debate: Sociedad, Ciencia y Tecnología; Vol. 3 Núm. 1 (2015): Febrero; 61-66Vigil Sanit Debate, Rio de Janeiro; v. 3 n. 1 (2015): Fevereiro; 61-662317-269Xreponame:Vigilância Sanitária em Debateinstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZporhttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/article/view/437/186Copyright (c) 2015 Vigilância Sanitária em Debate: Sociedade, Ciência & Tecnologia (Health Surveillance under Debate: Society, Science & Technology) – Visa em Debatehttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessCoelho, Caroline Corrêa de SouzaFreitas-Silva, OtnielAlcantara, IvanSilva, Janine Passos Lima daCabral, Lourdes Maria Correa2023-06-27T14:59:29Zoai:ojs.visaemdebate.incqs.fiocruz.br:article/437Revistahttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebatePUBhttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/oaiincqs.visaemdebate@fiocruz.br || gisele.neves@fiocruz.br2317-269X2317-269Xopendoar:2023-06-27T14:59:29Vigilância Sanitária em Debate - Fundação Oswaldo Cruz (FIOCRUZ)false |
