Page 236 Antimicrobial and antioxidant effect of pomegranate on bio yoghurt Forti�ed with its piths and juice Nanis H Gomah 1 , Mohamed T H 2 and 1 1 Faculty of Agriculture, Assiut University, Egypt 2 Agricultural Research Center (A.R.C), Egypt T he interest of eating healthy food has become obsession of the world. Bio yoghurt is a very favorite food which can be healthier by fortifying it with a natural source of vitamins, antioxidant and phenolic compounds. e aim of this study was to investigate the eect of bioactive compounds such as phenolic compounds, antioxidant, organic acids, carotenoids, and vitamins of pomegranate(Punicagranatum L.) juice, piths and depth at dierent concentrations on activity and vitality of probiotics and lactic acid bacteria during fermentation as well as, yeasts and molds count aecting the prolong of the yoghurt shelf life from the rst day till two weeks of storage. Samples had shown that phenolic compounds such as Oleuropein,Coumarin, Ellagic, HydroxyTyrosol, Benzoic, Salycilic, Ferulic, Caeine, Vanillic, Caeic, Chlorogenic, Catecol, Catechein, Protocatchuic and antioxidant compounds including Vitamins A, E, C, D concentration was changeable with dierent treatment within the range of(Oleuropein 9.5-18.4 ppm, Coumarin 4797.9- 11219.3ppm, Ellagic 2.1 - 8.4 ppm, HydroxyTyrosol 17.6 -56.8 ppm, Benzoic 5.5- 9.9 ppm, Salycilic 0.8 -5.8 ppm, Ferulic 3885 - 8668.8ppm,Caeine 5704.9 - 10457.9ppm, Chlorogenic 29029 - 122708.2 ppm, Catecol 2301.1 - 71847.3 ppm, Catechein 3 - 19 ppm, Protocatchuic16899.4 - 40515.4 ppm)and Vitamins (Vitamin A 0.067 - 1.17, vitamin E 0.073 - 1.96, vitamin C 75.95 - 171.27, vitamin D 0.33 -2.63 ppm). e eect of pomegranate juice on molds and yeasts was also studied in agar plats showing a clear zone of fungi surrounding the injected juice but there was no eect on the yeasts growth. Key Words: antioxidant, phenolic compounds, antimicrobial activity, pomegranate juice and pith, shelf life extension Biography Nanis H.
