Table 2.
Percentage of vit. D2 retention after thermal treatment at 50 ℃ incubated at different times in the dark. Number of repetition for each treatment: n = 3. The data are represented here as the mean ± S.D, where *p < 0.05, **p < 0.01, ***p < 0.001, ns is non-significant, vit. D2 (5 μg) vs vit. D2 (5 μg) + quercetin (5 μg), vit. D2 (5 μg) vs vit. D2 (5 μg) + quercetin (10 μg). Statistical significance analysis was carried out through one-way analysis of variance (ANOVA) prism.
