Fourteen red-fleshed plum (Prunus salicina Erhr. and hybrids) and eight peach [Prunus persica (Batsch) L.] genotypes were characterized for their total phenolic and anthocyanin contents. Selected rich phenolic genotypes showed high antioxidant activity, stable colour properties and good antimicrobial activity. Results indicated positive correlations between phenolic compounds (r 2 = 0.83) and antioxidant activity for both types of fruit. Colorants prepared from an anthocyanin rich plum genotype showed similar hue to that of synthetic colorant FD&C red 3 and higher stability than a commercial red grape colorant with respect to time, temperature and pH. Additionally, a selected rich phenolic plum genotype exhibited strong antimicrobial activity against Salmonella Enteritidis and Escherichia coli O157:H7. This study proposes that selection of crops high in phenolic compounds can be related to enhanced functional properties and opens the possibility of breeding fruits with targeted functional properties for the fresh produce and processing market. 2005 Elsevier Ltd.
