PHYSICAL AND CHEMICAL INDICATORS OF HONEY DEPENDING ON STORAGE TERMS AFTER PROCESSING COLONIES OF BEES BY CHLORAMPHENICOL

This article assesses the physical and chemical parameters of honey from linden for 30 and 120 day of the storage after applying various methods of treating bee colonies with 0.1% solution of chloramphenicol. The degree of preservation of the physicochemical composition of natural honey depending on the timing, storage conditions and antibiotic residues remains an important issue now. From the literature it is known that the degradation of antibiotic residues in honey during storage for 6 months in the dark at a temperature of 25 °C was different depending on the botanical origin of the honey to which the antibiotic is added. Three groups of the bee colonies were formed for this experiment: one control group and two research ones. The first experimental group was fed sugar syrup with adding of chloramphenicol, and the second was sprayed with 0.1% chloramphenicol solution. It was dissolved in 100 ml of boiled and cooled to 25 °C water, mixed thoroughly with freshly prepared sugar syrup and poured into each bee colony with 0.5 kg to feed the antibiotic with a 0.1 g. syrup. 0.1% active solution of chloramphenicol was used with the Rosinka fine pump sprayer for the aerosol treatment of hives. Processing of bee families of the control group was not performed by us. It was established that the physicochemical parameters of linden honey during the storage for 30 and 120 days vary depending on the processing of the bee colonies with the solution of chloramphenicol and correspond the requirements of the current national standard, except for the mass fraction of water and the mass fraction of sucrose. So, on the 30^th day of the storage the indicator of the mass fraction of water when feeding the bees of a syrup with chloramphenicol was 22.13±0.14% and 120 days – 22.26±0.06%, which is probable (p≤0.01) more than 5.03% and (p≤0.001) by 5.13% doesn`t correspond the requirements of the current national standard according to control groups. The mass fraction of sucrose was 6.13±0.14% on the 30<sup>th</sup> day of the storage and 6.10±0.15% on the 120<sup>th</sup> day, which is significantly (p≤0.001) more than in the control group, respectively by 2.50% and by 2.37%, which doesn`t correspond the requirements of the current national standard
