Abstract
This thesis is devoted to the production of useful chemicals from some agroindustrial wastes available in Egypt. The thesis is divided into 5 chapters:- Chapter I -Isolation and characterization of pectins prepared from some agro-industrial wastes by the traditional and the modified method and toxicity studies . Chapter 2 -Pharmacological experiments of the prepared pectin from apple pomace including hypolipidemic activity and gastro-protective property. Chapter 3 industrial application of the prepared pectin includes: 1- Use of pectin in slow release formulation 2-Evaluation of pectin as binder and disintegrating agent in tablets manufacture 3-Isolation of galacturonic acid from apple pectin hydrolysate 4-Use of pectin as carrier for microbe immobilization Chapter 4 The microbial production of citric acid from apple pomace marc left after pectin extraction and pectin including optimization of culture conditions. Chapter 5 Chemical investigation of some wastes It includes: 1- Citrus essential oils 2-Phytochemical investigation of sugar beet wastes
