Honey is a natural sweet substance produced by bees from plant nectar or secretions from live plant parts or from plant-sucking insect excretions. Bees collect, transform and combine these with their own specific substances and deposit, dehydrate, store and leave them on the hive to mature and age. Mexico is the fourth largest honey producer in the world. Eight honey samples were studied considering aspects palynological, bromatological and physicochemical. Regarding pollen richness, these honeys belong to Class II and III, which correspond to pollen-rich honeys. Regarding moisture, values from 10.55% for S1 honey to 18.14% for LC were found. For ash, LC honey had a lower percentage (0.07%) while EM honey had a greater percentage (0.42%). A maximum protein value of 0.63% was found, corresponding to EC honey. All the honeys analyzed were within the reference values (89.29% for honey S2 and 81.66% for LC) for nitrogen-free extract. Regarding ethereal extract, values of 0.01% and 0.08% were found while water activity (a_w) in the honey had values from 0.55 to 0.65. The pH of the honeys was between 3.73 and 4.16. The electrical conductivity of the honeys analyzed was between 0.27 and 0.50 mS/cm. Reducing sugars content was between 63.72 and 84.33%, corresponding to EC and ADA honeys, respectively. The results of this study indicate that the honeys analyzed are within the National and International standards.
