A method to reduce the aldehyde content of a pine chemical composition is disclosed. The pine chemical composition is selected from gum turpentine, gum rosin, CST BLS, CTO, depitched CTO, DTO, TOH, TOR, TOP, TOFA, fractionated TOFA, TOFA dimer, TOFA trimer, TOFA monomer, isostearic acid, stearic acid, and ester- and amide derivatives thereof. The pine chemical composition is treated with an aldehyde scavenger such as anthranilamide at a temperature between 20 °C to 300 °C, for 1 minute to 5 hours.
