Encapsulation technology has been used in the food industry to
provide ingredients with an effective barrier against environmental
and/or chemical interactions, thereby enhancing their stability to
temperature, moisture, oxidation and light exposure while
extending their shelf life. Food products that could benefit from
encapsulation include vitamins, colorants and nutrients (Barbosa-
Canovas, Ortega-Rivas, Juliano, & Yan, 2005, chap. 8)
