Food Chem Toxicol, 2012 Sep 25This study has the objective of evaluating the stability of B complex vitaminsand its vitamers, for a period of one year of storage. The pollen samples werestored under room temperature (with and without light) and frozen. The vitaminswere quantified by HPLC with fluorescence detection. All proposed vitamins werefound in the samples and the dehydration process didn't interfere in vitamincontent. The variations were (dry basis): 0.59-1.09 mg/100g (B(1)); 1.73-2.56(B(2)); 6.43-15.34 (PP) and 0.33-0.68 (B(6)). After one year of storage, it can be stated that vitaminB(1) concentration remained constant, while for the others, the concentrationloss was dependent on time rather than on storage conditions. All samples wereconsidered Vitamin B(2) sources. The influence of the storage time in theconcentrations of vitamin B6 and PP was explained mathematically, throughlinear regression equations of multivariate analysis.
