Abstract Esterfication is an important tool for protein modification, since it blocks free carboxyl groups raising the net positive charge. The obtained results can be summarized as follows: Sesame seeds meal contained moisture (8.79%); ether extract (1.16%); ash (6.05%); crude fiber(18.26%); crudeprotein(51.05%) and total carbohydrates(41.74%). The optimum conditions for isolating proteins from sesame seeds meal were at pH 10, and 1:30 sample to solvent ratio, for 60 min at 45ᵒ C using 0.5 N NaOH as a solvent, where the best conditions to reach 86.4% proteinesterfication by microwave were 560 microwave power for 20 min and 20 meq of 5 N Hcl/g protein as catalyst and hexanol as a solvent. Using modified proteins helped to improve the physical and microbiological properties of same vegetables and fruits. On the other hand it was safe upon subjecting to biological evaluation |
