2.4. Statistical analyses
Results were analyzed by ANOVA with the SAS software package (SAS, 2001). The model assumptions of homogeneity of variance and normality were probed by means of Levene's and Shapiro–Wilk's tests, respectively. Variance (var) and degree of freedom (df) of each treatment, time of storage, state of maturity and parameter analyzed was calculated. Pooled standard deviation (Pooled SD) for all measurement physical determination was calculated. Means were then compared by a Fisher test at α ≤ 0.05.
