San Martín Region is located in the high jungle area of northeastern Peru, with great potential for honey production due to its climate, orography and vegetation. The objective of the study was to determine the physicochemical and sensorial characteristics of honeys from the Mayo river basin. Twenty samples of honey were taken from five zones of the Bajo Mayo ecosystem of the San Martín Region, belonging to the towns of Zapatero, Lamas, Juan Guerra, Las Palmas and Banda de Shilcayo. The samples were collected directly from the bee farms. Different physicochemical parameters were determined such as humidity (21.5 to 23.2 g/100g), reducing sugars (0.16 to <0.0025 g/100g of sucrose), ash (0.14 to 0.53 g/100g), density (1.40 to 1.43 g/cc), pH (3.04 to 3.73), electrical conductivity (100 to 170 mS/cm), water activity (0.63 to 0.69) and soluble solids (77.3 to 78.5 g/100g). Likewise, sensory evaluations (visual aspect, aroma, mouth-retronasal aroma-, mouth-taste-, and properties of barrier to UV light (transmittance). The honey (Apis mellifera L.) coming from the district of Banda de Shilcayo expressed the best overall score in terms of sensory evaluation, compared to the other studied honeys.

Keywords : honey; Apis mellifera L; physicochemical parameters; reducing sugars; sensory evaluation; transmittance.
