title: Evaluation of fruit quality, bioactive compounds and total antioxidant activity of flat peach cultivars.
abstract: BACKGROUND
  Fruit quality traits (fresh weight, dry weight, soluble solids content, titratable acidity and firmness) as well as the content of bioactive compounds (phenolic compounds) and total antioxidant activity were evaluated in four commercial cultivars of peach (Greta, Ufo 4, Rome Star and Ufo 6) and four of nectarine (Neve, Planet 1, Maria Carla and Mesembrina) differing in fruit shape (standard or flat) and flesh colour (white or yellow), important cultivars of the Italian and foreign market. The higher fruit organoleptic quality and nutritional profile of flat peach and nectarine cultivars make them candidates for exploiting new market opportunities and the chance to improve profits of farmers.
  
  
  RESULTS
  The results showed that assayed quality parameters differed greatly among cultivars. In particular, flesh color and fruit shape accounted for most of the variation in traits underlying organoleptic and nutritional quality.
  
  
  CONCLUSIONS
  Overall data suggested that the flat white-fleshed nectarine Planet 1, the yellow-fleshed nectarine Mesembrina and the yellow-fleshed peach Ufo 6, because of their profiles in terms of soluble solids content, titratable acidity and bioactive compounds, have the greatest potential to meet current consumer requirements.
