Abstract Nano-encapsulation is a developing area of study across several fields, including the food, pharmaceutical, and cosmetic sectors. In this study, nanocapsules containing polyphenols were made from canola meal by electrospraying, it was determined how capsules' walls affected their shape, encapsulation efficiency, ζ-potential, particle size. Furthermore, impact on oil examined using TBA ...

Antimicrobial resistance (AMR) has been identified as one of the biggest health threats in world. Current therapeutic options for common infections are markedly limited due to emergence multidrug resistant pathogens community and hospitals. The role different essential oils (EOs) their derivatives exhibiting antimicrobial properties widely elucidated with respective mechanisms action. Recently,...

The main goal of this research was to compare the in vitro release rates of nano- and microcapsules of Silybum marianum extract (SME) in animal simulated gastric and intestinal medium conditions. The extract was encapsulated within sodium alginate carriers using emulsification/internal gelation method. Particle size, zeta potential, polydispersity index (PDI) and morphology of...
