Короткий опис(реферат):
Вивчено вплив деяких фізико-хімічних показників
монофлорного та поліфлорного меду Одеської області: уміст вологи та
кислотності на його мікробіологічні показники. Встановлено, що у пробах
меду, які мали більш високий рівень кислотності та менший уміст вологи
значення КМАФАнМ було найнижчим. Кількість Bacillus spp у
досліджуваних пробах була у межах від 4 КУО/г до 15 КУО/г, а Clostridium
botulinum - від1 КУО/г до 4 КУО/г, а в деяких пробах меду спорових
мікроорганізмів не було виявлено. Изучено влияние некоторых физико-химческих показателей
монофлорного и полифлорного меда Одесской области: содержание влаги кислотности на его микробиологические показатели. Установлено, что в пробах меда, которые имели более высокий уровень кислотности и меньшее содержание влаги показатель КМАФАнМ было самым низким. Количество Bacillus spp в исследованных пробах была в пределах от 4 КОЕ/г до 15 КОЕ/г, а Clostridium botulinum –от 1 КОЕ/г до 4 КОЕ/г, в некоторых пробах меда споровых микроорганизмов не было выявлено.

Study of the moisture content of acidity in mono- and polyfloral
types of honey Odessa region and microbiological parameters of these types of
honey. Investigated five varieties of fresh honey, including monofloral three types:
Lime, Sunflower honey and 2 types of polyfloral: Flower - color of fruit trees
(apricots, apples, cherries) and honey from herbs that have been selected from a
random sample three apiaries Odessa region in May and June 2015 each class
were selected honey 3 sample. We used the organoleptic research; humidity is measured using refractometric method. The total acidity of honey was determined by titration titrimetric method of solution of honey 0,05 N NaOH. total mesophiles determined by seeding 10-fold dilutions honey on special for this nutrient agar, Bacillus spp vyzachaly by heating dilutions of honey to 80 ° C for 10 minutes and after cooled immediately plated on Petri dishes with commercial agar polimeksynom B and incubated at 30 ° C. for 48 hours.
It was established that the average water content was lower in Monophlore types of honey and amounted to 15.9%, while both types of honey was flornyh this figure was on average 18.5%. In monophloral honey samples a higher moisture content in honey was a darker color - sunflower (16.4%) compared with lighter
monofloral types of honey. The total acidity was higher in honey with fruit trees
and a sunflower honey. Average pH in the investigated samples of honey was 3.54. Monofloral types of honey were 2.6% lower moisture content than was in polyfloral types of honey. Total count of mesophilic bacteria was within the permissible norms in samples of honey that had a higher level of acidity and a lower moisture content value Total count of mesophilic bacteria was the lowest. Bacillus spp number of samples studied was in the range of 4 CFU / g 15 cfu / g, and Clostridium botulinum - from 1 CFU / g to 4 CFU / g, and in some samples of honey spore microorganisms were found.
