**7. Food flavoring by coating**

Edible coatings act as a physical barrier to prevent the widespread migration of contaminants from the environment into foods and vice versa. These barrier qualities are crucial for ensuring the safety of food. Consumers desire greater food safety, as well as improved nutritional and Flavor qualities. In recent years, active packaging has been developed to extend food shelf-life by improving and increasing coating properties and functionalities. For instance, adding active ingredients, such as Flavors, might give edible coatings more activity. To protect their activity and qualities, Flavors can either be encapsulated or added directly to the edible polymer matrix.
