Abstract:

Innovative functional flours with the trade name Q-Farin were used in the preparation of biopolymer materials with properties adequate to the production of biodegradable multifunctional packaging. To meet the assumed goal, it was necessary for  the modification and functionalization of starch-protein material derived from the milling of purified wheat grain to confer hydrophobic, thermoplastic and barrier properties upon it. Unmodified and modified functional flour with the tradename Q-Farin C1000 was plasticized by  pressure-thermal treatment in a mixture with typical plasticizers: glycerol, sorbitol & ethylene glycol. The modification of starch was accomplished by its esterification with acetic acid, enzymatic esterification with oleic acid or by oxidation with hydrogen peroxide. Mechanical and viscoelastic properties of the granulated thermoplastic compositions were examined. Their structure (microscopic and SEM observation), thermoplastic and processing properties as well as their susceptibility to biodegradation and phytotoxicity were also assessed. Selected thermoplastic compositions with adequate properties were processed into film and shapes. The materials obtained were  examined for their physical properties like grammage and strength. Parameters of the technology processes involved were also prepared.
