Physicochemical, bioactive properties and antioxidant of Apis mellifera L. honey from western Paraná, Southern Brazil

Abstract

The Southern region of Brazil is known for its floral diversity, presenting great potential for bee products such as honey, pollen, propolis and royal jelly. In this study, 67 honey samples provided by beekeepers from 14 municipalities of western Paraná were evaluated. Physicochemical parameters, bioactive compounds and antioxidant activity were analyzed. The physicochemical parameters of the samples were in compliance with the specifications by national and international standards, presenting average values of 3.26, 34.54 meq.kg-1 , 18.75%, 10.79 mg.kg-1 , 0.14% and 340.10 µS.cm-1 , for pH, acidity, moisture, hydroxymethylfurfural, ash content and electrical conductivity, respectively. The nutritive values of honey, on average, achieved 0.28% of protein from 69.09% of total sugars, 64.57% of reducing sugars and 4.28% of sucrose. Bioactive compounds showed average values of 34.83 mg GAE/100 g-1 of total phenols and 16.26 mg EQ/100 g-1 of flavonoids, enabling antioxidant activity of 2.68 µmol FE (II)/g-1 of FRAP, 1.01 µmol ET/g-1 from ABTS and 0.12 µmol ET/g-1 of DPPH. This first study evaluated the parameters through cluster analysis and observed nine groups formed, as well as the characteristics between the samples with similar reaction. We concluded that the honey samples have high similarity and confirmed the quality of the honey produced.

Physicochemical characterization, bioactive compounds and antioxidant activity of apis mellifera honey from western paraná state, brazil

“…These results were similar to those reported by other studies for humidity (CAMARGO et al, 2014;GALHARDO et al, 2020). A research in previous years showed similar pH values to those found for honey samples from the same region.…”

Investigation of parameters in restaurant food waste for use as poultry rations

“…As a result, management programs are needed to recycle waste (Olszewska et al, 2020) properly. Due to rapid population growth and increasing demand for food, the amount of food waste produced in urban communities is increasing rapidly (Chen et al, 2012;Galhardo et al, 2021).…”

Antimicrobial activity, physical-chemical and activity antioxidant of honey samples of Apis mellifera from different regions of Paraná, Southern Brazil

“…Evaluation of samples from 14 municipalities in Western Paraná, presented values similar to those observed in this study, this low content of total flavonoid and total phenol. It may be due to the high percentage of samples of light shades of honey produced in the region, where the authors observed 67.16% of the samples presented light amber color (Galhardo et al, 2020). This characteristic of honey from the Western region is associated with a botanical origin that has a dominance of Hovenia dulcis (Moraes et al, 2019) which presents lighter shades of honey (Nascimento et al, 2018).…”
