Рисовый крахмал сорта «Маржан» и маниоковый крахмал сорта «Cassava 531» подвергались физической модификации методом облучения с дозами 0, 3, 6 и 9 кГр с применением ускорителя ILU-10. Пленкообразующие растворы готовились путём смешивания крахмала, хитозана и глицерина, после чего осуществлялось литьё и сушка. Метод поочерёдного варьирования одного фактора (OFAT) применялся для оценки влияния содержания крахмала, времени клейстеризации, содержания глицерина и хитозана на свойства пленок: прочность на разрыв (TS), удлинение при разрыве (EAB), паропроницаемость (WVP) и прозрачность.</p><p>Для многофакторной оптимизации использовался метод поверхности отклика (RSM) на основе дизайна Бокса-Бенкена (BBD). Регрессионная модель прозрачности (%) показала, что содержание крахмала и хитозана оказывает положительное линейное влияние, однако это влияние уменьшается из-за выраженных отрицательных квадратичных членов. Время клейстеризации и содержание глицерина показали отрицательное линейное влияние на прозрачность, а также были выявлены значимые взаимодействия факторов.</p><p>Несмотря на умеренную статистическую значимость модели (R² = 35,05%), она выявила сложные взаимозависимости факторов и позволила определить направление для оптимальной формулы. Полученные результаты подтверждают потенциал облучённого крахмала в качестве функционального компонента биоразлагаемых пленок и создают основу для дальнейшей разработки устойчивых упаковочных материалов с улучшенными физико-механическими и барьерными свойствами.</p></abstract><trans-abstract xml:lang="en"><p>This study aimed to develop and optimize edible antimicrobial films using electron beam-irradiated starches and biopolymer additives. Rice starch (“Marzhan” variety) and cassava starch (“Cassava 531” variety) were physically modified via irradiation at doses of 0, 3, 6, and 9 kGy using an ILU-10 accelerator. Film-forming solutions were prepared by blending starch, chitosan, and glycerol, followed by casting and drying. One-Factor-at-a-Time (OFAT) screening was conducted to evaluate the effects of starch content, gelatinization time, glycerol, and chitosan on film properties including tensile strength (TS), elongation at break (EAB), water vapor permeability (WVP), and transparency.</p><p>A Box–Behnken Design (BBD) based on Response Surface Methodology (RSM) was used for multi-factor optimization. The regression model for transparency (%) revealed that starch and chitosan contents had positive linear effects but exhibited diminishing returns due to significant negative quadratic terms. Gelatinization time and glycerol content showed negative linear effects on transparency, while several interaction terms also influenced the response.</p><p>Although the model demonstrated modest statistical significance (R² = 35.05%), it highlighted complex factor interdependencies and provided direction for optimal formulation. The findings support the potential of irradiated starch in functional biodegradable films and offer a foundation for future development of sustainable packaging materials with improved physical and barrier properties.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>съедобная пленка</kwd><kwd>облучение крахмала</kwd><kwd>хитозан</kwd><kwd>биоразлагаемая упаковка</kwd><kwd>оптимизация прозрачности</kwd><kwd>метод поверхности отклика (RSM)</kwd><kwd>дизайн Бокса-Бенкена</kwd></kwd-group><kwd-group xml:lang="en"><kwd>edible film</kwd><kwd>starch irradiation</kwd><kwd>chitosan</kwd><kwd>biodegradable packaging</kwd><kwd>transparency optimization</kwd><kwd>response surface methodology (RSM)</kwd><kwd>Box–Behnken design</kwd></kwd-group><funding-group xml:lang="en"><funding-statement>This research has been funded by the Ministry of Science and Higher Education of the Republic of Kazakhstan grant number BR21882447 «Development of a food safety system in longterm storage conditions based on electrophysical and radiation treatment methods».</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Biocontrol of Pathogen Microorganisms in Ripened Foods of Animal Origin / J.
