Abstract:		"Bee pollen's nutritional and beneficial health properties depend on the botanical origin and storage conditions. Palynological analysis determines the botanical composition of the multiflora and colour fractions. This study aimed to characterize the phytochemical profile and antioxidant activity of Tuscan bee pollen stored at freezing temperature for 2 years to verify the preservation of nutraceutical properties of the multiflora and colour fractions. Polyphenols, flavonoids content, antioxidant activity and volatile compounds profiles were measured. Non-terpene derivatives (acids and aldehydes) represented the main class of volatile compounds in most analysed samples. Among the colour fractions, coral showed significant differences in the antioxidant compounds. In the multiflora were also determined the soluble sugar content (128.33 mg/g of fresh weight) and mineral content, with the prevalence of K, organic N and Ca. The results suggest that the freezing storage of bee pollen for a long period can be still used as food"
