¹⁾

Values with different superscripts in the same column are significantly different. NS means not significant.

²⁾

The method for MDA determination employed the incubation step of reaction mixtures (sample + chemicals) for 2 hr in a 95°C water bath, thus MDA could be artificially formed from its precursor fatty acids during the analysis.

³⁾

The value reflects the amount of non-volatile aldehydes, principally 2-alkenals.
