Sweet cherries cultivar Aksehir Napolyon were dipped in ethanol
extracted propolis (EEP) and water extracted propolis (WEP) in various
concentrations immediately after harvest and then kept at 0 ºC, 85-90 %
relative humidity for 4 weeks. The following treatments were applied
to the fruits: dipping in water, dipping in ethanol (70 %), dipping in 1,
5 and 10 % concentrations of ethanol extracted propolis and dipping in
1, 5 and 10 % concentrations of water extracted propolis. The effects of
propolis on incidence of fungal decay and fruit quality (weight loss,
total soluble solids, titratable acidity, skin colour, stem browning, surface
pitting, appearance and taste) were assessed at weekly intervals during
storage. Ethanol extracted propolis treatments were effective in preventing
fungal decay in cherries for 4 weeks, but adversely affected sensory
quality and stem colour of cherries.
