Physio – Chemical Parameters of Some Libyan Samples

A total number of ۲۰ Libyan honey samples were collected from different areas in Libya through ۲۰۱۶ – ۲۰۱۷ , 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 ۳.۲۵ to ۵.۰۰ , with a mean of ۴.۱۰۱ . These values are comparable to the pH values of U.S. honey (range ۳.۴ to ۶.۱), the moisture content of honey samples range from ۷.۷۶ to ۱۵ % which is found within the limits prescribed by Codex Alimentarious Commission(۱۹۶۹), i.e. not more than ۲۱%.The mean of ash content of honey samples were ۰.۳۱۳ %, with the range of ۰.۱-۰.۹۵ %. These values are comparable to the values of U.S. honey which has mean of o.۱۶۹%, with a range from ۰.۰۲۰ to ۱.۰۲۸%.The Hydroxymethylfurfural (HMF) content of Libyan honey samples are found within the limits prescribed by the Codex Alimentarious Commission(۱۹۶۹), Insoluble matter content of Libyan honey samples range from ۰.۰۰۵ to ۰.۱۴۹ % . with mean of ۰.۰۶۱۷۵ % . The range of proline content of Libyan honey samples arek from ۳۵۰ to ۱۰۷۹.۴ mg / kg, with mean of ۶۲۶.۲ mg / kg.
