Abstract We investigated the literature to find the bioactive compounds’ profile of Brassicaceae microgreens and the influence of different production systems and the elicitors use in its overall quality. For this, a summary of the latest progress in bioactive compounds qualification and quantification are presented in the relevant databases. Determining the exact role of production systems is not a straightforward process, although it seems to have greater influence according to the intended plant. From the nutritional point of view, the microgreens production demonstrates a high content of bioactive compounds. The use of elicitors, as one of the dependent variables, appears to increase the concentrations of bioactive compounds, especially the use of the light. Besides that, the conditions of growth, harvest and processing remain crucial factors that should be considered in the successful development of the seed. quality this databases process plant view variables light growth seed

RESUMO: Extratos de taninos (com e sem enxague) foram comparados com o uso de hipoclorito de sódio e água em alface crespa minimamente processada, sob atmosfera modificada. Foram avaliadas diferença total de cor e análises microbiológicas após a sanitização e durante o armazenamento dos produtos (9 dias à 3°C). O extrato de tanino SM(r) com enxague apresentou resultados semelhantes aos da solução de cloro para todos os parâmetros analisados e, além disso, apresentou uma elevada redução da contagem inicial microbiológica de alface minimamente processada. No entanto, durante o armazenamento, SM(r) não apresentou melhores resultados do que o uso de água. Portanto, SM(r) poderia ser utilizado na desinfecção da água de lavagem das alfaces, reduzindo a microbiota inicial e, assim, impedir a contaminação cruzada durante o processamento mínimo de vegetais.

ABSTRACT: In the present study, tannin extracts (rinsed or not) were compared to the use of sodium hypochlorite and tap water on fresh cut crisp leaf lettuce stored under modified atmosphere packaging. Effects of these sanitizers on total color difference and microbial levels of the product after sanitization and storage for 9 days at 3°C were evaluated. Performance of rinsed SM(r) tannin extract was comparable to the results of chlorine solution for all the analyzed parameters and; furthermore, that extract presented a high reduction in the initial bacterial count of minimally processed lettuce. However, storage of tannin extracts, did not impart better outcomes than the use of tap water. Therefore, the tannin extract storage SM(r) could be used in washing water to reduce the initial microbiological load, avoiding cross contamination in vegetables minimally processed.
