Abstract
In this work, the effect of packaging materials [polypropylene (PP), polypropylene/ethylene vinyl alcohol/polypropylene] on pH, color parameters, the intensity of the ongoing oxidative processes (TBA value) and instrumental texture indicators (hardness, shear force, elasticity) were investigated in bacon derived from two groups differ in the way of feeding (C – control group and E – group fed supplementation with rapeseed and linseed oils), both in the fresh condition and after storage at 4°C for up to 14 days. Smoked bacon stored in oxygen barrier packages (PP/EVOH/PP) showed lower TBA values and characterized by darker and more red color than that stored in packages more permeable to O2 (PP). Therefore multilayer barrier sheet materials such as PP/EVOH/PP could be utilized successfully to extend commercial quality of smoked bacon during its fourteen day of refrigerated storage compared to polypropylene materials. Additionally supplementation of animal diet with 2% rapeseed oil and 2% linseed oil can allow to obtain pork bacon enriched in unsaturated fatty acids with no negative influence on its quality because there were no appreciable differences between samples taking into account most of the examined parameters. Although some differences for color parameters were reported in experimental group compared to control group, they are of little practical implication and would still provide satisfactory quality for consumer.
