| Abstract: | The
scientists at Turkey have evaluated the effect of packaging materials
and storage conditions on sunflower (Helianthus annuus Linn.) oil
quality. During experiment glass and polyethylenterephthalate (PET)
bottles filled with sunflower oil were stored under both light and dark and
with/without headspace to determine the effects of light, air, packaging
materials and storage time on the stability of sunflower oil. Peroxide value
(PV), free fatty acids, soap content and iodine number were measured to
determine stability of sunflower oil every 3months until 9 months. Glass bottles
recorded lower oxidation values than oils packaged in PET. The oxidation
proceeded faster in packages stored in light than in darkness, and in those with
headspace. The best quality oil was found stored in the dark, free of air and
packed in glass and then in PET. Even though glass gave the best protection
against oxidation, PET bottles offer adequate protection (especially in the
dark). This study showed that air, packaging and storage time all have an effect
on the stability of sunflower oil [Kucuk M and Caner C, Effect of packaging materials and storage
