摘要: Abstract The propolis has potential to be a natural food additive. However, its application is limited, because it alcohol-soluble and strong flavour. Microencapsulation may an alternative for reducing these problems. aim of this study was encapsulate extract by complex coacervation using isolated soy protein pectin as encapsulant agents. studied function pH (5.0, 4.5, 4.0 3.5) the concentration encapsulants core (2.5 5.0 g/100 mL). Samples obtained at in both concentrations were lyophilized analyzed hygroscopicity, encapsulation efficiency, particle size, morphology, thermal behavior, stability phenolic flavonoids during storage, well antioxidant antimicrobial activities. It possible obtain form powder, alcohol-free, stable, with property, activity against Staphylococcus aureus possibility controlled release foods.
