摘要
The aim of this experimental study was to assess the effects of various plastic-based packagings on quality changes in mayonnaise during storage. The plastic packaging materials examined were PET, PET with an oxygen scavenger incorporated during extrusion (PET with Amosorb), and PET coated with an oxygen and carbon dioxide barrier. Packed mayonnaise was stored at 20 degrees C and removed monthly for chemical, microbiological, sensory and rheological analysis during storage over a period of six months. The ranking of oxidative stability in mayonnaise was glass = PET-Amosorb > PET-coating > PET. A sensory panel was unable to distinguish samples stored in glass from samples stored in PET-Amosorb or PET-coating. There was no significant difference in the linear viscoelastic properties of mayonnaise packaged in glass or plastic materials during storage.
