Effect of the addition of ultraviolet absorber (Tinuvin 234) on the quality of soybean oil packaged in polyethylene terephthalate (PET)

2005

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 resistance between the linear coefficients of each treatment indicates that significant difference does not exist (p
