Physicochemical characterization of honeys from Brazilian monitored beehives

This study was performed with floral honeys from an innovator and pioneer project in Brazil for the digital monitoring of beehives. Samples from six regions of the Santa Catarina state were evaluated for moisture, acidity, pH, electrical conductivity, 5-HMF, diastase activity, fructose, glucose, suc...

Description
Summary:This study was performed with floral honeys from an innovator and pioneer project in Brazil for the digital monitoring of beehives. Samples from six regions of the Santa Catarina state were evaluated for moisture, acidity, pH, electrical conductivity, 5-HMF, diastase activity, fructose, glucose, sucrose, and minerals (K, Ca, Na, Mg, and Mn). Furthermore, chemometric analyzes were applied to classify honeys based on these parameters. Some results did not corroborate with the current legislation for free acidity (≤ 50 mEq kg −1 ) and electrical conductivity (≤ 0.8 mS cm −1 ). In all samples, the minerals K (0.37 × 10 3 to 3.03 × 10 3  mg kg −1 ) and Ca (0.03 × 10 3 to 0.38 × 10 3  mg kg −1 ) were majority. Considering that the results were different ( p
