• •Physicochemical parameters of stingless bee honeys differ of A. mellifera honey.•SDS–PAGE protein patterns show distinctive bands for each kind of honey.•Conventional physicochemical parameters could determinate the authenticity of honey.•Proteins profiles of honeys could be used to establish their entomological origin. Increasing production of stingless-bee honey and the prospect of broader marker for natural and organic products indicate the need to establish parameters to determinate the entomological origin and authenticity of honey. In this research, honeys of Apis mellifera, Melipona beecheii and Trigona spp. were collected in Yucatan, Mexico. Stingless-bee honeys contained more water and less total sugars and reducing sugars. SDS–PAGE patterns show distinctive bands for each kind of honey. The SDS–PAGE pattern of A. mellifera proteins honey showed three bands with molecular weights between 10.2 and 74.8kDa, there were five proteins bands in M. beecheii honey with molecular weights between 6.1 and 97.0kDa and nine for Trigona spp. proteins between 9.3 and 86.7kDa. Conventional physicochemical parameters along with electrophoresis profiles of stingless-bee honeys proteins could be an alternative for determination of entomological origin.
