Determination and evaluation in terms of healthy nutrition of the pyridoxal, pyridoxine and pyridoxamine forms of vitamin $B_6$ in animal-derived foods

Abstract

In many studies, vitamin B6 is given as the sum of the pyridoxal (PL), pyridoxine (PN) and pyridoxamine (PM) forms. In a limitednumber of studies, PL, PN and PM forms of vitamin $B_6$ in animal origin foods were reported. Since the bioavailability of PL, PN andPM forms of vitamin $B_6$ are different; knowing the amounts of these forms in foods is important in terms of healthy nutrition. In thisstudy, the PL, PN and PM forms in a total of 38 animal-based foods were determined by high performance liquid chromatography(HPLC). PL and PM were found predominantly in fish, meats and chicken samples. Within these, the highest amount of vitamin $B_6$were found in golden grey mullet by 616.3 µg/100g, in veal fillet at 376.1 µg/100g and in chicken breast by 329.5 µg /100g, respectively.The PL form in total vitamin B6 ranged in fish between 32.5 and 53.1%, in meats between 15.6 and 48.9%, and in chicken samplesbetween 59.9 and 69.8%. It was also found that milk and milk products contain low amounts of vitamin $B_6$. Based on these results, allanimal-based foods were found to be rich in terms of the PL and PM forms. The results of this study will play an important role in thecreation of various diets for healthy nutrition.
