THE INFLUENCE OF LIGHT TRANSMITTANCE AND GAS PERMEABILITY OF VARIOUS PACKING MATERIALS ON THE QUALITY OF WHOLE NATURAL YOGURT DURING STORAGE.

INFLUENCE DE LA TRANSLUCIDITE ET DE LA PERMEABILITE AUX GAZ DE DIFFERENTS MATERIAUX D'EMBALLAGE SUR LA QUALITE DU YOGOURT ENTIER NATURE EN COURS DE STOCKAGE.

Summary

THE EXPERIMENTAL CONDITIONS WERE: TEMPERATURE 281 K (8 DEG C) ; LIGHTING AT 0 AND 2,000 LUX ; STORAGE TIME UP TO 24 DAYS ; PACKAGING OF 180 G IN EITHER GLASS JARS (TRANSPARENT, COLOURLESS OR BROWN) OR POLYSTYROL CUPS (TRANSPARENT, COLOURLESS OR BROWN, OR COVERED WITH CARDBOARD) ; IN AN UPRIGHT OR UPSIDE DOWN POSITION. FROM THE MEASUREMENTS ON THE CHEMICAL AND MICROBIOLOGICAL COMPOSITION AND PEROXIDE VALUE, SIGNIFICANT DIFFERENCES IN THE CHANGES OF THE PRODUCT WERE NOTED AS A FUNCTION OF THE CONDITIONS OF STORAGE. THE BROWN COLOURED CONTAINERS OR THOSE WITH CARDBOARD WERE FOUND TO PROVIDE BETTER PROTECTION THAN THOSE WHICH WERE TRANSPARENT AND COLOURLESS. UP TO 2 WEEKS OF STORAGE, THE DIFFERENCES IN LIGHT TRANSMITTANCE WERE MORE IMPORTANT THAN THE DIFFERENCES IN GAS PERMEABILITY.
