Abstract
This studies aimed to determi.ne physical and chemical properties  of clover honeys in Egypt. Eleven clover honeys samples from different governments in Egypt were analyzed results are presented from  specific gravity, viscosity (Poise)color, granulation , EC (ppm),TSS % , moisture % ,pH ,free acidity mq/kg, lacton  mq/kg, total acidity mq/kg ,fructose %, glucose %, sucrose % and maltose %  .
The results indicated that specific gravity was parallel and ranged from  1.4548 to 1.4050 with mean 1.4100, viscosity  from 34.9 to 93.05 with mean 46.93(Poise), color from 0.14 to 0.36 with mean 0.23 ,granulation  from 1.760 to 1.437 with mean 1.630, EC from 247.5 to 100.0 ppm with mean 155.5,TSS from 80.38 to 82.75 with mean 81.0 % .   
Chemical properties showed that moisture was parallel and ranged from 19.25 to 17.5 with mean 18.76,  pH ranged from 3.70 to 4.15 with mean 3.8 ,Free acidity 76.5 to 18.5 with mean 35.31 mq/kg , Lacton  5.0 to 45.0 with mean 11.5 mq/kg ,total acidity from 81.0 to 25.5 with mean  43.75mq/kg, fructose from 40.43 to 37.57 %  with mean 39.03, glucose 33.0 to 30.2 with mean 31.5% , sucrose 1.2 to 6.03 % with mean 3.56, maltose  8.0 to 3.5 with mean 5.2% and  proline ranged form 51.35 to 23.55 mg/kg with mean 34.07 mg/kg.
It is clear that the biochemical variation can be useful separating at least some different honeys within different types
