Abstract: In this work, the effect of the addition of the UV absorber Tinuvin 234 on the quality of soybean oil packaged in PET bottles stored at ambient temperature for 6 months under fluorescent light (634 lux). Along this period determinations were made of: Peroxide value (PV), Free fatty acids (FFA), Specific extinction at 232 and 270 nm (EE) and Sensorial evaluation (SE). The analysis of variance and contrast between the linear coefficients of each treatment indicates that significant difference does not exist (p<0.0001) during the storage in relation to all determinations (PV, FFA, EE and SE). The results indicate that the addition of the absorbent Tinuvin 234 to PET bottles in the concentrations of 0.12% and 0.22% was not efficient in slowing down the deterioration of the oil exposed to the fluorescent light, when compared with soybean oil in PET bottles without addition of Tinuvin 234.
