What is wood rosin glyceride?

Glycerol esters of wood rosin (GEWR) are complex mixtures of diglycerides and triglycerides of wood rosin resins, with residual monoglycerides. In addition, neutral substances (non-acid saponifiables and unsaponifiables) and residual free resin acids are present. Wood rosin is obtained by solvent extraction of aged pine stumps, followed by a liquid-liquid solvent refining process. Refined wood rosin consists of about 90% resin acids and about 10% neutral substances. The resin acid part is a complex mixture of isomeric diterpene monocarboxylic acids, with a typical empirical formula C20H30O2, and its main components are dehydrogenated rosin and rosin acid. GEWR is produced by esterifying resin acids with food-grade glycerol. The product is then purified by steam stripping or direct countercurrent steam distillation.
These specifications exclude substances derived from rosin, the exudate of live pine trees, and substances derived from tall oil rosin, a by-product of kraft (paper) pulp processing.
