Abstract
Two natural extracts, from rosemary (Rosmarinus officinalis L.; Nutrox) and lemon balm (Melissa officinalis L.; Meliox) showing a potential antioxidant activity, have been evaluated and compared with a synthetic antioxidant (Butylated hydroxytoluene; BHT) and a control batch. Pork meat patties were made by addition of the mentioned compounds, cooked and packed in modified atmosphere and stored under illumination for 6 days. A descriptive sensory analysis was also conducted. The patties with natural extracts showed higher a*-values (P<0.001) than control and BHT samples. Cooked pork hardness was the lowest for Meliox batch after 0 and 3 days of storage in comparison with the rest of the batches. Nutrox batch showed the lowest TBARS values and hexanal content (P<0.05) throughout the storage period. The batches with natural antioxidants produced the highest concentrations of free thiol groups after 0 and 3 days. Differences in sensory attributes among batches were not detected by the judge panel.Entities:
