Encapsulation and release kinetics of apitoxin from alginate-based microparticles

Apitoxin, or honey bee venom, contains various enzymes, polypeptide toxins, and other substances, some of which are allergenic or immunogenic or both. Studies indicated that apitoxin aqueous solutions may be used as a potential new agroecological insecticide. The apitoxin solution of various concentrations (2 to 6 g L-1 ) was used for the preparation of calcium-alginate microparticles (80 μm nozzle). Release kinetics were observed as a cumulative release (%) of apitoxin from dry and wet microparticles in distilled water and a buffer solution (NaHCO3 / Na – citrate, pH = 8.28). Kinetics curves showed different patterns and significantly slower release of apitoxin from dry microparticles in comparison with wet microparticle in water (26% vs. 100% cumulative release after seven days) and a buffer solution (100% cumulative release in 18 min vs. 4 min and 30 s). Microcapsules were characterized based on parameters such as encapsulation efficiency (EE%), loading capacity (LC), size (μm), and a swelling degree (%) in an aqueous medium. Loading capacity vs. apitoxin concentration plot showed linear correlation (R² = 0, 9929) with a slope of 0.0127 while other parameters remained almost constant with different concentrations. The obtained results indicated that there is a significant difference in kinetics properties between dry and wet apitoxin microparticles.
