Abstract
El objetivo del estudio fue determinar la calidad microbiológica del filete de Dosidicus gigas “pota” precocido, sazonado, congelado y envasado de una empresa de hidrobiológicos de Paita, entre los meses enero a diciembre del 2022. La metodología empleada correspondió al tipo aplicada y enfoque cuantitativo, tomándose como unidad de análisis a los reportes de análisis microbiológicos de producto en proceso y producto terminado, para la producción de filete de Dosidicus gigas “pota” precocido sazonado, congelado y envasado. Se obtuvo el reporte de 304 muestras, de las cuales 115 fueron de filete precocido en cremolada, 94 de filete precocido sazonado y 95 de producto terminado. Del análisis de resultados se tiene que el 8.35% de las muestras tuvieron recuentos de bacterias aerobias mesófilas viables entre 1.8– 5.57 x 10¹ufc/g, mientras que el 59.21% recuentos entre 5.1 – 5.31 x 10²ufc/g y el 32.24% restante con recuentos entre 2.43 – 4.78 x 10³ufc/g. Respecto a Escherichia coli, todas las muestras fueron negativas, al igual que para Staphylococcus aureus y Salmonella sp. Se concluyó que el 100% de muestras presentaron recuentos microbiológicos de bacterias aerobias mesófilas viables dentro de los límites permitidos, así como la ausencia de microorganismos patógenos, lo que sugiere un adecuado control de calidad e higiene alimentaria, evidenciando la eficacia de las medidas de control de calidad implementadas durante el procesamiento y envasado, asegurando la confianza del consumidor y la salud pública.
The objective of the study was to determine the microbiological quality of the pre-cooked, seasoned, frozen and packaged Dosidicus gigas "pota" fillet of a hydrobiological company in Paita, between the months of January and December 2022. The methodology used corresponded to the type applied and quantitative approach, taking as the unit of analysis the reports of microbiological analysis of product in process and finished product, for the production of pre-cooked Dosidicus gigas "pota" fillet, seasoned, frozen and packaged. A total of 304 samples were obtained, of which 115 were pre-cooked steak, 94 were seasoned precooked steak and 95 were finished products. From the analysis of results, 8.35% of the samples had counts of viable mesophilic aerobic bacteria between 1.8 – 5.57 x 10¹ufc/g, while 59.21% had counts between 5.1 – 5.31 x 10²ufc/g and the remaining 32.24% had counts between 2.43 – 4.78 x 10³ufc/g. All samples were negative for Escherichia coli, as were Staphylococcus aureus and Salmonella sp. It was concluded that 100% of the samples presented microbiological counts of viable mesophilic aerobic bacteria within the permitted limits, as well as the absence of pathogenic microorganisms, this suggests adequate quality control and food hygiene, evidencing the effectiveness of the quality control measures implemented during processing and packaging, ensuring consumer confidence and public health.
