Physicochemical, Antioxidants and Sensorials Properties of Melipona subnitidaHoney after Dehumidifying

摘要

Physical-chemical characteristics (moisture, water activity, electrical conductivity, pH, free acidity, reducing sugars, apparent sucrose, hydroxymethylfurfural, ash, insoluble solids and color), total phenolic content, flavonoids, antioxidant and sensorial properties (aroma, flavor, color, fluidity, acceptance and purchase intention) were evaluated in honey bee Melipona subnitida in natura and after dehumidification. The data were submitted to analysis of variance (P<0.01), the means compared by the t-test (p<0.05) and the sensorial analysis by the Friedman test (p<0.05). Comparing the dehumidified honey with the in natura honey, differences in the physical and chemical characteristics of moisture, water activity, reducing sugars, sucrose, ash, insoluble solids in water and color were observed. However, there was no difference in antioxidant capacity, total phenolic content, flavonoids, flavor, color, acceptance, and intention to purchase the product. In the sensorial parameters of aroma and fluidity were evidenced alterations; however, the process of dehumidification of the honey did not impair it sensorial quality and still decreased the humidity favoring its greater conservation.
