Nutritional Value and Antioxidant Activity of Honeys
Produced in a European Atlantic Area
Food Chem, 2013 Jun 1;138(2-3):851-6
One hundred eighty-seven honey samples from an Atlantic
European area were studied to determine their nutritional compositions and
antioxidant capacities, as well as the relationships between them. The results
showed that heather, polyfloral, blackberry, and eucalyptus honeys had the
highest carbohydrate contents, whereas honeydew and chestnut honeys had the
lowest. There were some important differences among the honey types, which were
related to the presence of minor components. The protein contents were
significantly higher in honeydew and chestnut honeys, and the same results were
obtained for mineral contents. Related to the presence of several antioxidant
compounds, heather honey had the highest phenolic content, whereas honeydew and
chestnut honeys had the highest flavonoid contents. Multivariate analysis
showed that some variables, such as the amounts of flavonoids, minerals,
proteins, and phenols, were significantly correlated with antioxidant activity.
The regression analysis produced a significant model (R(2)=0.716; F=154.680; P <
0.001) that related the antioxidant activity and the flavonoids, K, and P
contents.
