MaterialThirty kilograms of cherrie

Material
Thirty kilograms of cherries (P. avium) were harvested
by hand in June, 1999 from Ayas, village in Ankara.
They were put in carton boxes and immediately
transported to the laboratory by a car (METU- Food
Eng. Dept.) for the experiments. They were washed and
dried, and defective ones were eliminated before treatments.
After washing and drying, the cherries were
divided into two major groups: control and Semperfresh
TM coated. The control groupc onsisted of cherries
with no SemperfreshTM fruit coating. The SemperfreshTM
coated groupcons isted of two sub-groups: 10 g/L
SemperfreshTM coated and 20 g/L SemperfreshTM
coated. Half of the cherries from each of the above
groups was stored at ambient temperature (B3073 1C)
and at ambient humidity (40–50% RH), the other half
of the cherries was stored at cold storage (0 1C) and at
ambient humidity (95–98% RH).
SemperfreshTM edible coating
SemperfreshTM is an edible coating solution which is
composed of sucrose esters of fatty acids, sodium
carboxymethyl cellulose and mono-diglycerides of fatty
acids was obtained from ACC group(was distiributed
from Semper Bio-Technology Ltd., U.K.) in liquid
concentrate form (500 g/L). It was diluted with distilled
water to obtain the desired concentrations (10, 20 g/L).
The diluted solutions were mixed for 30–45 min with
occasional stirring and then applied on the cherries.
Coating was applied by dipping the cherries into the
SemperfreshTM solutions for about 1 min
