Abstract
Cruciferous sprouts (e.g. broccoli and red radish) are rich source of health-promoting phytochemicals more concentrated than the adult plant edible organs; however, these tiny microgreens need cold storage conditions to preserve their quality to reach the consumers in microbiologically safe conditions, maintaining their composition and acceptability. In this work, the microbiological status and phytochemical composition of broccoli and radish sprouts were evaluated at harvest (Day 0), and after seven and fourteen days of storage at two different temperatures, 5 and 10 °C. Pathogenic microorganisms were absent during shelf-life; nevertheless, the slight growth of Enterobacteriaceae organisms, aerobic mesophilic and psychrotrophic bacteria, molds and yeasts was assessed. The temperature of storage highly influenced the quality and content of bioactives in the sprouts, and for practical applications, the storage at 5 ºC is the most suitable option. Moreover, these fresh crucifers remain acceptable for consumers after a long refrigerated storage period (14 d), being an interesting option for consuming fresh and naturally-functional foods.
