The impact of cultivation systems on the nutritional and phytochemical content, and microbiological contamination of highbush blueberry

Abstract The aim of this study was to compare the nutritional and use value of berries grown in organic and conventional systems. The polyphenol content, fruit colour and firmness, and yeast, mould, and mycotoxin contents were assessed in blueberry fruit freshly harvested and stored for 8 weeks in c...
