| dc.description.abstract | The Ethiopian traditional fermented alcoholic beverages including (‘Tella’, ‘Tej’, ‘Shameta’,‘Bordie’ and ‘Korefie’), traditional distilled alcohols (‘Wheat Berkrakie Areki, ‘Wheat Sharata Areki’, ‘Dagusa Arefa Areki’, ‘Dagussa Sharata Areki’, ‘Dagim Areki’, ‘Gibto Areki’, ‘Wheat Arefa Areki’, ‘Mixed Areki’, ‘Koso Areki’ and ‘Yemar Areki’) and factory produced alcoholic beverages (‘Vodka Areki’, ‘Lomie Areki’, ‘Ananas Areki’, ‘Ouzo Areki’ and ‘Dry Gin Areki’) were collected from Addis Ababa, Ethiopia for the measurement of their ethanol, methanol, solid, salinity contents, acid value, pH value and electrical conductivity. The overall average values of pH value, ethanol% (v/v), acidic content (g/L), solid content (mg/L), conductivity (μS/cm) and salinity (%) found in all of the beverages studied were in the range of 4.6 - 7.5, 2.80 - 51.2, 0.02 - 105, 0.00 - 20328, 5.87- 8391 and 0.1 - 4.6, respectively. The methanol contents of the beverages were determined using GC-MS. The results showed that the level of methanol in some of the studied traditional and factory alcoholic beverages were found in the range between 0.867 - 0.979% (v/v). No methanol was observed in all of the analyzed traditional fermented beverages. Hence, contrary to the general assumptions, the levels of methanol observed in the analyzed drinks do not pose any health threat to the human. However, the normal alcohol health risk associated with high consumption remains a problem. | en_US |
