Abstract

This chapter discusses the polymer-based oleogels prepared from direct and indirect approaches in more details. Ethyl cellulose (EC) can be considered to be a near-natural polymer, which is chemically synthesized by etherification of natural cellulose. By controlling the degree of substitution (DS) and degree of polymerization, different grades of EC can be obtained. Chitin is the second-most abundant natural polymer on earth, exceeded only by cellulose. Most food polymers are hydrophilic in nature, and accordingly, they have long been used for structuring water-based gels. Cellulose derivatives such as hydroxyl propyl methyl cellulose (HPMC) and methylcellulose (MC) served as excellent materials for creating porous cryogel with exceptional oil sorption properties. An innovative indirect method was developed to create oleogels from protein hydrogels by replacing water with vegetable oil through a step-wise solvent exchange route.
