N1 - Funding Information: Production of starch nanoparticles, native starch-, amorphous starch- and nano starch-based films, as well as determination of physicochemical properties of films were carried out with financial support from the Grant of the Administration of the Novosibirsk Region (project no. GR-9). Mechanical treatment of native starch, X-ray diffraction, and differential scanning calorimetry of native starch, nano-sized starch, amorphous starch-, nano starch- and native starch-based films were supported by the Russian Science Foundation (project no. 22-73-00124). Production of glucose syrup, preparation and quality assessment of confectionery products were supported by the state assignment to the Institute of Solid State Chemistry and Mechanochemistry SB RAS (project no. FWUS-2021-0005). Publisher Copyright: © 2022 by the authors.

N2 - This study demonstrated the feasibility of comprehensive enzymatic conversion of starch for non-waste applications in food industry. Enzymatic conversion of starch gives rise to nano-sized particles that can be used for manufacturing biodegradable and edible packaging materials and glucose syrup for replacing sugar in confectionery formulations. The 96 h enzymatic hydrolysis yielded starch nanoparticles smaller than 100 nm. Films based on nano-sized starch particles have promising physicochemical properties for manufacturing biodegradable and edible packaging materials. Such properties as reduced moisture content, increased homogeneity, crystallinity, and high initial thermal stability improve the mechanical and performance characteristics of the final food packaging materials. During film formation from starch subjected to preliminary mechanical amorphization, the polymer chain is recrystallized. The C-type crystal structure of starch is converted to the B-type structure. The supernatant obtained by starch hydrolysis can be used for producing glucose syrup. The resulting glucose syrup can be used as a sugar substitute in production of confectionery products. No objective technological differences in properties of glucose syrup obtained by comprehensive conversion of starch and the commercially available glucose syrup derived from sucrose were revealed.
