a nonstandard finite difference (nsfd) scheme has been constructed and analyzed for a mathematical model that describes lotka–volterra food web model. this new discrete system has the same stability properties as the continuous model and,on the whole, it preservesthe same local asymptotic stability properties. linearized stability theory and schur–cohn criteria are used for local asymptoticstab...

in order to improve food texture, hydrocolloids are used widely as gelling material in food systems. wild sage seed has remarkable amounts of gum (mucilage) with good functional properties. this mucilage also improves the rheological, textural and functional properties of foods. in this study the effects of different drying methods including hot air drying (40, 50, 60, 70 and 80°c), freeze dryi...

Objective(s): Biodegradable film is widely used because it is free from synthetic substances and does not lead to environment pollution. This study aimed to prepare and characterize biodegradable sago starch films loaded with Carboxymethyl Cellulose nanoparticles. Methods: Sago starch films were prepared and plasticized with sorbitol/ glycerol by t...
