Microbiological safety of ready‐to‐eat minimally processed vegetables in Brazil: an overview

Abstract

The market of ready‐to‐eat minimally processed vegetables (RTE‐MPV) is increasing in Brazil and many other countries. During processing, these vegetables go through several steps that modify their natural structure while maintaining the same nutritional and sensory attributes as the fresh produce. One of the most important steps is washing‐disinfection, which aims to reduce the microbial load, prevent cross‐contamination and inactivate pathogenic microorganisms that may be present. Nonetheless, the presence of pathogens and occurrence of foodborne illnesses associated with consumption of RTE‐MPV concern consumers, governments and the food industry. This review brings an overview on the microbiological safety of RTE‐MPV, focusing on Brazilian findings. Most of the published data are on detection of Salmonella spp. and Listeria monocytogenes, indicating that their prevalence may range from 0.4% to 12.5% and from 0.6% to 3.1%, respectively. The presence of these pathogens in fresh produce is unacceptable and risky, mainly in RTE‐MPV, because consumers expect them to be clean and sanitized and consequently safe for consumption without any additional care. Therefore, proper control during the production of RTE‐MPV is mandatory to guarantee products with quality and safety to consumers. © 2020 Society of Chemical Industry

Qualidade microbiológica de polpa de frutas no Brasil: Um panorama dos anos 2010 a 2020

“…Enquanto isso, os fatores que estão relacionados com a contaminação nas etapas que ocorrem após a colheita estão geralmente relacionados as falhas de higiene por parte do manipulador, ou mesmo, contaminação de equipamentos, utensílios e veículos de transporte. Além disso, o uso de água de lavagem contaminada, irregularidades no armazenamento e embalagens impróprias também são aspectos importantes na contaminação de polpa de frutas (Sant'anna et al, 2020).…”

Molienda De Zanahoria: Una Estrategia Para Producir Alimentos Con Valor Agregado

“…Los snacks generalmente son alimentos que tienen un gran valor comercial por su facilidad de manipulación y consumo, pero un reducido valor nutricional debido a su alto procesamiento (19,20). Sin embargo, en los últimos años la mayoría de investigaciones se han enfocado en la obtención de alimentos más nutritivos, fáciles de manipular y, sobre todo, mínimamente procesados (21,22). De acuerdo con un análisis realizado por ProChile, en el 2017 se estimó que el mercado mundial de los snacks se encontraba por encima de los 375.000 millones de dólares, de los cuales el 50% de este valor correspondía a la venta de snacks naturales y un 30% a la venta de snacks orgánicos (23).…”
