Combined effects of octenylsuccination and oregano essential oil on sweet potato starch films with an emphasis on water resistance

The perishable character of moist food products demands packages with antimicrobial activity and water resistance. Oregano essential oil (OEO) and starch octenylsuccination were first jointly applied to formulate antimicrobial and water-resistant sweet potato starch films. The results showed that octenylsuccination powerfully retarded the coalescence of oil droplets in film casting process and favoured their homogeneity in the dried films. OEO...
