In this study, the influence of cranberry fruit extract on the chemical composition, ripening
indices, oxidative stability, and microbiological as well as organoleptic properties of the white
soft cheese was evaluated. Different concentrations of cranberry fruit extract powder (500,
750 and 1000 ppm) were added during the storage period at 5 ± 2ºC for 8 weeks. Cranberry
fruit extract treatments had a significant effect on the yield and recovery of fat, protein and
total solids of fresh cheese. Treated fresh or stored cheese have significantly less numbers of
total, psychrotrophic, enterococci, proteolytic, lipolytic bacteria and yeast and mould counts
than the control cheese. It could be concluded that cranberry extract could successfully used at
concentration up to 750 ppm to improve the keeping quality of white soft cheese.
