| Abstract | ||
| The optimum acidic conc. determined for each solvent and the distribution ratio (D) and extraction percent (E %) also determined. The optimum acidic media for extraction with Hexane by using 0.5M HCl while for extraction with ether by using 1M HNO3 . The temperature fixed at 25C0. In this research it has been determined the optimum conditions for extraction of benzoate (sodium benzoate) that used as food additives and beverages. In extraction process two organic solvents used (hexane and ether) and used (HCl, HNO3 and H2SO4) as acidic media with molar concentrations (0.1, 0.2, 0.5, 0.6, 0.7, 1 and 1.5 molar) respectively. The percent of benzoate estimated in some type of beverage and was found to be in the limited international level (5mg/1kg). | ||
