ABSTRACT Porous microspheres were fabricated utilizing the sol–gel phase transfer method of microcrystalline cellulose, exhibiting a three‐dimensional porous structure with notable adsorption capabilities. Employing these cellulose as carrier, sodium chlorite precursor and acid activator, physically adsorbed chlorate to level 20.029 mg/g. Subsequently, chlorine dioxide (ClO 2 ) sustained‐release system was prepared through chemical reaction citrate‐adsorbed in sealed environment, theoretically yielding cumulative ClO release 11.957 The profile found be significantly influenced by factors such temperature, humidity, type activator content hygroscopic agent. Notably, rate from wet microsphere could modulated adjusting temperature. By fitting data an S‐curve, underlying pattern elucidated. Mathematical modelling revealed that operation encompasses two distinct stages: stage diffusion stage. Water serves prerequisite for initiating stage, leading induction period dried system. During this period, water absorption triggers reactions, allowing adjustment amount duration variation agent content. These findings demonstrate adjustability system, positioning it promising green bactericidal use preservation packaging fruits vegetables. When applied grape preservation, effectiveness assessed monitoring key indicators decay rate, firmness, soluble solids titratable acidity. results confirmed demonstrated favourable preservative effects on grapes, effectively prolonging their storage over 5 days without compromising quality or altering natural flavour.
