Quality parameters of apple fruits marketed in Iaşi

Abstract

Apples are the most consumedfruits in Romania, all over the year. In the present work were studied fruits of 7 apple cultivars (Golden Delicious, Idared, Jonagold, Florina, Jonathan, Starkrimson, Renet) commercialized in 3 open-markets from the city of Iaşiat the end of April. The main analysed quality parameters were: soluble solids content, acidity, total sugars, sugar/acid ratio. Renet cultivar proved the highest total sugars and soluble solids contents, while Florina, the lowest.The most acid was Idared (Sârca) and the less acid were Starkrimson and Golden Delicious.The best values for sugar/acid ratio (over 75) were obtained by Starkrimson and Golden Delicious, and the smallest ones (less than 33) byIdared (Sârca), followed by Jonathan, Jonagold and Idared (Suceava).
