دراسة لتفاعلات الأكسدة للسكريات في بعض المواد الغذائية

Abstract

This research concerned with the study of the oxidiation reactris of some natural products as : whey, Dates Al – Zahidi , Treacle , starch of corn , Banana and water melon , with some oxidizing agent like: conc . nitric acid , in the presence of V2O5 as catalyst ( at room temperature ) and permanganate ion in acidic medium . The results obtained indicate clearly , that oxalic acid is the major product during oxidiation of natural products with conc . nitric acid in the presence of V2O5 as catalyst , liquid N2O4 also obtained as a side product . while mucic acid is obtained as a major product when we used permanganate ion as oxidizing agent . The products were identified by spectroscopic methods and thin layer chromatography ( T.L.C )
