ABSTRACT:
See-through, packaging structures for liquid or semi-liquid fruit or vegetable products, which have a polyamide food contact-layer of at least 0.4 mil. thickness, extends the color-life of the contained food product. The polyamide layer removes certain degradation products of polyphenolic compounds which otherwise would cause browning during storage. The packaging structures allow the contents and their color to be clearly seen by using a transparent film or sheet structural material having a polyamide surface-layer, the structural material being formed into a packaging structure. The packaging structure may be one such as a film pouch or a plastic bottle, the surface layer of the film or sheet forming the inner-surface food contact-layer of the packaging structure. Alternatively, a polyamide inner contact-layer in the lidding of a see-through package structure can be used, in which case the see-through package container portion itself need not have a polyamide inner contact-layer.
