Characteristics physicist-chemistries of honeys produced in combs different of the age

Abstract

Honey color is a characteristic related to the flower source and plays a major role on consumers buying preference. When finished, honey is placed in wax honeycombs that are composed mainly by hydrocarbons, esters and a small percentage of fatty acids and alcohols that give to wax the plasticity and ability to absorb several kinds of elements. The consecutive comb reutilization might transfer pigments to honey that, in turn, can alter honey final characteristics. In the present study the objective was to evaluate the influence of comb reutilization on honey physico-chemical and color characteristics. The experiment was carried out using randomized blocks with four treatments and six repetitions. Each hive was considered a block. The treatments consisted of boxes with sheet of alveolated wax and honeycomb with one, two or three years of usage, totaling 24 boxes. Honey samples were analyzed by diffuse reflectance spectrophotometry and the physico-chemical properties were analyzed by laboratory standard tests. The diffuse reflectance, total sugar, pH, acidity and ash did not varied significantly among treatments (p > 0.05). Honey color produced in honeycomb with different years of use was similar amongst treatment; however, the honey produced in sheets of alveolated wax had clearer color and less sugar content.
