摘要：
A method for manufacturing light-colored purified tall oil rosin includes a distillation process of distilling unpurified tall oil rosin in a presence of activated carbon. A method for manufacturing a tall oil rosin ester includes a rosin production process of producing light-colored purified tall oil rosin by this method for manufacturing, an esterification process of carrying out an esterification reaction of the purified tall oil rosin obtained in the rosin production process and alcohols, and an antioxidant-addition-process of adding at least one antioxidant selected from a sulfur-based organic compound, a thiophosphite-based organic compound and a phosphorus-based antioxidant during or after the esterification process.
