2.4. Experimental design and statistics
The experiment was laid out in a randomized block design with
factorial arrangements. Data were analyzed for variance by using
the SAS (V 9.3, SAS Institute Inc., USA) package. Comparisons were
made between treatments (EFF, calcium nitrate, control), and
observed changes in parameters during storage. When interactions
between treatments and storage intervals were found significant
(p
0.05), the effect of each treatment and interval was deter-
mined by pairwise mean comparison using Tukey HSD. The data
pertaining to decay incidence (%) and organoleptic rating (out of 9)
were subjected to square root transformation prior to analysis of
variance.
