Research Concerning the Influence of the Use of Energo-protein Supplements-eco Certificate upon Physical-chemical Honey Indicators

Abstract

Abstract Numerical growth of global population, technical-scientific and socio-economical evolution determinate the increase of food need and diversification. In these conditions, beekeeping acquires an increasingly important role as food providers, but also as a vehicle to boost production by pollinating entomophilies cultures. Thus, the aim of present work is to highlight the influence of the use of energo-proteic supplements eco certificated represented by honey with added 10% rape pollen, sunflower, linden and trees upon some physical-chemical parameters of acacia, linden and rape honey. The analyzes performed show that water in honey samples was within the recommended range for a high quality honey. Whatever the energo-protein supplement used hydroxymethylfurfural content presented to all the variants analyzed values below 1mg/100g of honey. Colorimetric index value of honey was framed in recommended high quality standards, the results obtained were below the maximum limits for each type of honey, and the protein supplements administrated to bee families had no influence. Regarding the content of glucose and fructose in honey samples, acacia honey had the highest amount of fructose compared to linden honey or rape honey, and the ratio of fructose and glucose ranged between 1.34-1.43. It can be concluded that the physical-chemical parameters analyzed in all three varieties of honey were located within the limits recommended by the European Commission and Codex Alimentarius, whatever the energo-proteic supplement used.
