Glucose oxidase (GOX) is widely used in bakery applications to improve dough rheology and bread quality. However, its direct addition formulations limits functionality due premature enzymatic activity. This study electrospraying encapsulate GOX using chia mucilage sodium alginate as biopolymeric wall materials. Three drying methods-critical point (CPD), Lyophilization/freeze-drying (LC), oven (OD)-were compared evaluate their impact on encapsulation efficiency (EE), activity retention, microstructural integrity. Our findings reveal that CPD preserved the porous structure of microcapsules, minimizing leakage yielding highest EE (70%). In contrast, LC induced ice crystal formation, disrupting polymer network leading a moderate (27.43%), whereas OD resulted extensive capsule shrinkage, causing significant enzyme loss (57.1%). The release kinetics during mixing were best described by Korsmeyer-Peppas model (R2 = 0.999), indicating non-Fickian diffusion mechanism influenced relaxation. These results demonstrate technique selection plays crucial role encapsulated enzymes' stability behavior, providing new insights for optimizing delivery applications.
