Ester Gum

Ester Gum

ESTER GUM is a steam-stripped, glycerol ester of tall oil rosin. The process conditions of gum grade ESTER GUM is tightly controlled to ensure a resin that meets the highest standards set forth by the Beverage industry for consistent good taste and low odor characteristics. ESTER GUM has achieved the high quality once dominated by the gum grade resins made from wood rosin. This consistency and high quality is assured through a very special quality control screening.

ESTER GUM is available in both solid and pastille (bead) forms. We recommend, however, that shipment of the resin be taken in the solid form, rather than the beaded form. This would reduce the possibility of the resin being oxidized, which could ultimately affect the taste and odor characteristics.
