| Abstract | ||
| This experiments was applied to the date samples of Al-sultani date palm cultivar (Semi hard types) obtained from Iraqi Company for Dates Marketing in Al-Shalcheya. Juice dates was obtained by solving dates in water as 1:3 ratio , followed by filtration and clarification of the sample. .Moisture, total soluble solids, total and reducing sugars, protein, ash and tannin percent were estimated and their values were15.5%, 84%, 80.9% ,73%, 0.70 %,1.622%,0.003% respectively , values of viscosity , pH and density were7.025 poise ,6.6,101170 gm/cm3 respectively .Thin layer chromatography technique was applied to juice sample for identification of aldehyde and ketone mono reducing sugars by spotting them on TLC plate and the spts were compared with standard solutions of glucose, galactose (aldehyde reducing sugars) and fructose (ketone reducing sugars ) . The image gave blue spots color for the aldehyde sugar and brown spots color for the ketone sugars. Rf values were estimated for all the spots . | ||
