Valorification of starch from waste solutions for the modernization of food industry, REZAMIDO

• modernizing of food production;
• obtaining valuable products conforming to the food security
  principles;
• developing a new methodology, efficient and nonpolluting, for valorification of some waste waters from food industry for obtaining valuable products;
• developing an enzymatic methodology, ecological and economical for reducing the production costs of process for obtaining floury pasta;
• a patent;
• PC 7;
• project proposal.

Project novelty is given by:

• investigation of composition of waste water resulted in foods industry in the floury pasta factories regarding their content in starch and other saccharides, metallic ions ant other compounds;
• the achievement of an experimental model for preliminary tests, the screening of available amylolyitc extracts;
• determination of influence of bioprocessing parameters (temperature, pH, metallic ions presence, eventual the introduction of some enzyme activators) on the composition of resulted solutions after enzymatic hydrolysis;
• the study of possibilities to combine different amylolytic extracts for obtaining the biggest hydrolysis degree and yield and the increase of glucose production;
• the study of addition of different extracts influence on the duration of hydrolytic bioprocess;
• achievement of database with the possible utilizations of starch containing wastewaters for obtaining valuable products for food industry with glucidic structure, especially glucose, dextrin, maltodextrin;
• the proposed technology – patentable, for valorification of the starch from residual fractions.

• testing of efficiency of different amylolytic extracts commercial available for enzymatic hydrolysis of starch;
• the influence of experimental parameters (starch concentration, substrate-enzyme ratio, temperature, pH, presence of Ca²⁺ ions, stirring intensity, the possibility of using some water insoluble enzymatic extracts (with immobilized enzymes) and achievement of process in (semi)continuous process;
• the study of process for solutions which contain some other compounds, with a similar composition with real waste solutions;
• finding concrete possibilities for using the resulted glucose syrup;
• proposal of some methods to obtain crystalline glucose from these aqueous solutions resulted by enzymatic hydrolysis of starch;
• enzymatic technology for hydrolyzing starch from wastewater solutions;
  the development of a mathematical model for describing the process;
• patent proposal;
• technical-economic analysis;
• PC7 project proposal.
