Oleogels and reverse emulsions stabilized by acetylated Kraft lignins

Acetylated Kraft lignins were evaluated for their ability of structuring vegetable oils into oleogels. Microwaveassisted acetylation was used to adjust lignin's degree of substitution according to reaction temperature (130 to 160 ◦C), and its effect in improving the viscoelasticity of the o...
