1Comparison between all samples, i.e., fresh and dried at different temperatures. Mean values in the same line with the same Arabic superscript are not statistically different according to ANOVA with post-hoc test Tukey at a 95% confidence level (p < 0.05): N = number of measurements, F = test statistic, p value = significance

2Comparison between the dried samples alone. Mean values in the same line with the same Greek superscript are not statistically different according to ANOVA with post-hoc test Tukey at 95% confidence level (p < 0.05): N = number of measurements, F = test statistic, p value = significance

3Test T for independent samples at 95% confidence level (p < 0.05), for comparison of two groups
