ECHEMI | Resin acids and Rosin acids, polymd., esters with glycerol

Lillian30 May, 2023Science

It is made by esterification of light wood rosin and food grade glycerin. Those used as gum gum bases are refined by steam stripping; those used as beverage stabilizers (adjusting the density of citrus essential oils) are refined by reverse steam distillation. Due to the bitterness of rosin glyceride, the rosin was modified to produce hydrogenated rosin, polymer rosin, and part of dimer rosin. The glycerides prepared therefrom are: hydrogenated rosin glyceride (hydrogenated ester gum), part of dimerized rosin glyceride, poly rosin glyceride, tall oil rosin glyceride, these products have improved rosin to a certain extent The bitter taste of glycerides enhances its use value in food.
