Resumo

This study evaluated the stability of vitamins C, E and β-carotene in six samples of bee pollen after their process, and in a one-year period of storage. After the pollen's process, there was a 67.1% increase for vitamin C (p <0.05), an 18.7% loss for vitamin E and 15.6% for β-carotene. Storage in freezer was the most efficient condition for the vitamins conservation; the loss in storage at room temperature (exposed or protected from light) was similar. Vitamin E appears to be better preserved during storage when compared to vitamin C and β-carotene. (AU)
