Crystallization of honey is a natural process and guarantee of authenticity. The aim of the study is to evaluate the influence of physico-chemical parameters on the process of crystallization and on crystal size. The interest in studying the factors influencing the crystallization process is due to the fact that most consumers, especially children, are reserved for the purchase and consumption of a crystallized honey, the commercial aspect being very important to them. Three samples of honey of

... different floral origins were used for the physico-chemical and microscopic analysis. The analyzes were carried out throughout 30 days every sample in triplicate. In terms of physicochemical following parameters were analyzed: acidity, diastase index, hydroximethylfurfural, humidity, invert sugar, glucose, fructose, fructose / glucose ratio and the microscopic analyze of crystals size. The parameter values resulting from the research study are in accordance with the legislation in force. Statistical analysis of experimental data highlights the influence of ratio fructose / glucose and humidity on the honey crystallization.
