Microencapsulated Vegetable Oil Powder

Abstract

Vegetable oil has been increasingly popular among consumption oils as it provides several health benefits such as antioxidant, anti-inflammatory, antivasoconstrictive, antiarrhythmic, antithrombotic, antimicrobial, antihypertension, antiaging, etc. Several applications of vegetable oils in foods, cosmetics, and pharmaceutical industries have been widely researched as it is made from natural products with a safe and reliable process. However, oxidative deterioration and stabilization of vegetable oil provide short shelf life storage with poor consumer acceptance. Thus, this chapter is aimed to give an overview of stabilization of vegetable oils using microencapsulation techniques mostly focusing on emulsion preparation using multilayer emulsion followed by a spray drying technique to obtain vegetable oil powder. Using different wall materials was discussed along with the application for several vegetable oils. Moreover, the characterization of encapsulated vegetable oil powder was summarized for the final product quality and encapsulated process efficiency.
