Physio – Chemical Parameters of Some Libyan Samples

Abstract

A total number of 20 Libyan honey samples were collected from different areas in Libya through 2016 – 2017 , from east, west, southeast and southwest regions. These samples were analyzed for six physiochemical parameters of honey control i.e.,pH, moisture, ash content, insoluble mater porline control and HMF . The aim of this study is to give view about the quality of Libyan honey, which is suffering from paucity of characterization data. The results of physiochemical characteristic of Libyan honey samples, the pH of Libyan honey samples range from 3.25 to 5.00 , with a mean of 4.101 . These values are comparable to the pH values of U.S. honey (range 3.4 to 6.1), the moisture content of honey samples range from 7.76 to 15 % which is found within the limits prescribed by Codex Alimentarious Commission(1969), i.e. not more than 21%.The mean of ash content of honey samples were 0.313 %, with the range of 0.1-0.95 %. These values are comparable to the values of U.S. honey which has mean of o.169%, with a range from 0.020 to 1.028%.The Hydroxymethylfurfural (HMF) content of Libyan honey samples are found within the limits prescribed by the Codex Alimentarious Commission(1969), Insoluble matter content of Libyan honey samples range from 0.005 to 0.149 % . with mean of 0.06175 % . The range of proline content of Libyan honey samples arek from 350 to 1079.4 mg / kg, with mean of 626.2 mg / kg.
