1996 | The formation of oligosaccharides and their influence in the high purity of final honeys
Main executives entity:  Cuban Institute of Sugar Research
Main author: Josefa Hormaza
Summary: Sucrose losses in final honey take place due to so many factors and in such a complex diversity of interactions that they cannot be studied in a simple way. In this work, it is carried out a global approach of the problem, and it is historically characterized the whole situation in the country. As a second aspect, the problem is valued from the economic point of view, in order to be able to appreciate the meaning of losses in final honey in a monetary language. Then, the most recognized causes are analyzed in a cause and effect diagram, and it is offered a summary of the studies carried out by the authors in the last years, which include some of those causes considered as significant by most of them: high sucrose solubility, high purity of the cooked mass, reproduction in masses and crystallizers, lengthening of the crystal and low exhaustion cycle. Diverse industrial examples, extracted from the authors' studies, illustrate the analysis of the causes. It was worlwide defined for the first time that oligosaccharides were the cause of sugar crystal's deformation, and it was quantified the role that it plays to increase final honey's purity, which was internationally recognized as a Cuban contribution. It is emphasized the importance of facing the problem in an appropriate way. For this purpose, complementary ways are suggested, such as stimuli systems, specific orientations and methodological actions. These solutions are presented, in a summarized form, in: Annex 1 " Payment of sugar cane for its quality", Annex 2 "Diagnosis of final honeys", Annex 3 "Conference for the introduction of quality improvement programs in Cuban sugar mills", and Annex 4 "Tools for the diagnosis in sugar industry”.
