ABSTRACT

Free polyphenolic acids content in four cauliflower cultivars – ‘Panther’, ‘Isabel’ F₁, ‘Amfora’ F₁ (cultivars with green curds) and ‘Coleman’ (cultivar with a white curd) was examined in 2001-2002. Cauliflowers were grown for harvest in spring, summer or autumn. The influence of gas composition of atmosphere during 6-week storage in a cold store (at the ambient atmosphere and at CA 5% CO₂ + 3% O₂) on polyphenolic acids content in cauliflowers harvested in autumn was also examined. Polyphenolic acids content was affected by period of growing and cultivar. Their concentration varied from 1.2 to 1.8 mg·g^-1 of f.w. (means of the two years). The highest polyphenolic acids concentration was found in cv. ‘Amfora’ F₁ and the lowest in cv. ‘Coleman’. During storage of cauliflowers polyphenolic acids concentration decreased. However, CA conditions inhibited to some degree changes in polyphenolic acids concentration i

Key words: cauliflower, cultivars, storage, CA, polyphenolic acids.
