Broccoli and radish sprouts are safe and rich in bioactive phytochemicals

Cruciferous sprouts (e.g. broccoli and red radish) are rich source of health-promoting phytochemicals that are more concentrated than in 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 5 and 10 degrees C. Pathogenic microorganisms were absent during shelflife; nevertheless, the slight growth of Enterobacteriaceae organisms, aerobic mesophilic and psychotropic bacteria, molds and yeasts was assessed. The storage temperature influenced the quality and content of bioactives in the sprouts, and for practical applications, storage at 5 degrees C is the most suitable option. Moreover, these fresh crucifers remain acceptable for consumers after 14 d storage period, being an interesting option for consuming fresh and naturally-functional foods. (C) 2017 Elsevier B.V.
