Significant differences (P < 0.05) were found among the contents of vitamin B6 in the dried samples, but as drying
temperature was increased from 60 to 80 C, a reduction in the degradation level was observed, with retention of 39% of the initial vitamin B6 content at 80 C. Therefore, it may be understood that longer exposure time to thermal treatment at lower temperature is related to a heavier thermal load that caused more damage to the phytochemicals than a higher temperature level.
