This study aimed at evaluating the effects of the addition of an oil/beer/lemon marinade solution with or without the inclusion of oregano, rosemary and juniper essential oils on the quality, the technological properties as well as the shelf-life and safety of vacuum-packed pork loin meat. The results obtained suggested that, aside from the addition of essential oils, the marination process allowed to reduce meat pH, thus improving its water holding capacity. Instrumental and sensorial tests showed that the marination also enhanced the tenderness of meat samples, with those marinated with essential oils being the most positively perceived by the panelists. In addition, microbiological data indicated that the marinated samples showed a lower microbial load of the main spoiling microorganisms compared to the control samples, from the 6th to the 13th day of storage, regardless of the addition of essential oils. Marination also allowed to inhibit the pathogens , and thus increasing the microbiological safety of the product. Overall outcomes suggest that the oil/beer/lemon marinade solution added with essential oils might represent a promising strategy to improve both qualitative and sensory characteristics as well as the safety of meat products.
本研究旨在评估添加或不添加牛至、迷迭香和杜松子精油的油/啤酒/柠檬腌制溶液对真空包装猪里脊肉的品质、工艺特性以及保质期和安全性的影响。所得结果表明,除添加精油外,腌制过程可降低肉的pH值,从而提高其持水能力。仪器分析和感官测试表明,腌制还增强了肉样的嫩度,添加精油腌制的肉样最受评审员好评。此外,微生物学数据表明,在储存的第6天至第13天,无论是否添加精油,腌制样品中主要腐败微生物的微生物负荷均低于对照样品。腌制还能抑制病原体,从而提高产品的微生物安全性。总体结果表明,添加精油的油/啤酒/柠檬腌制溶液可能是改善肉类产品质量和感官特性以及安全性的一种有前景的策略。
