Preserving apple (Malus domestica var. Anna) fruit bioactive substances using olive wastes extract-chitosan film coating
Apple fruits have components of therapeutic nature. Such components, to a great extent, decline or decompose during post-harvest that negatively affect fruit shelf-life. Chitosan fruit-filming has proved useful in maintaining these compounds. This study aims, therefore, at enhancing Chitosan coating...
