Mechanism of emulsifiers
A number of different chemical and physical processes and mechanisms can be involved in the process of emulsification: • Surface tension theory – according to this theory, emulsification takes place by reduction of interfacial tension between two phases • Repulsion theory – According to this theory, the emulsifier creates a film over one phase that forms globules, which repel each other. This repuls… WebThe main group consists of terpenes, terpenoids, and other aromatic and aliphatic constituents, characterized by a low molecular weight [ 11 ]. The main component of this Citrus genus is δ-limonene, followed by β-pinene, α-terpineol, and other components that vary qualitatively and quantitatively.
