A blend of oregano and thyme essential oils (EOs) incorporated edible film was evaluated to improve the storage quality of chicken meat patties. Several preliminary trials were carried out to optimize the levels of bio-polymer to obtained desired edible film as a carrier and blend of EOs as bio preservatives. Preliminary studies indicated that 1.5% (w/v) solution of carrageenan as bio-polymer and 0.10% (v/v) oregano with 0.15% (v/v) thyme EOs in blend form as antimicrobial were suitable. Chicken meat patties wrapped with edible film incorporated with aforementioned EOs, packaged aerobically were stored at refrigeration temperature (4 ± 1 °C) for further studies. Results of refrigeration storage, showed that control samples had significantly higher pH and thiobarbituric acid reacting substances value than EOs treated products. There were significantly lower microbial counts observed in treatment samples (with EOs) and found well within permissible limit as compared to control. All the treatment samples showed lower or comparable flavour score in regard with control. It was found that shelf-life of chicken meat patties increased significantly (< 0.05) during refrigerated storage and showed acceptable quality up to storage period of 30 days.
对含有牛至和百里香精油(EOs)的可食用薄膜进行了评估,以提高鸡肉饼的储存质量。进行了几项初步试验,以优化生物聚合物的用量,从而获得所需的可食用薄膜作为载体,并优化精油混合物作为生物防腐剂的用量。初步研究表明,1.5%(w/v)的角叉菜胶溶液作为生物聚合物,以及0.10%(v/v)的牛至与0.15%(v/v)的百里香精油混合作为抗菌剂是合适的。用含有上述精油的可食用薄膜包裹的鸡肉饼,在有氧包装下,于冷藏温度(4±1°C)下储存,以进行进一步研究。冷藏储存结果表明,对照样品的pH值和硫代巴比妥酸反应物质值显著高于经精油处理的产品。与对照相比,处理样品(含精油)中的微生物数量显著更低,且均在允许范围内。所有处理样品与对照相比,风味评分更低或相当。结果发现,鸡肉饼在冷藏储存期间的保质期显著延长(<0.05),并且在长达30天的储存期内都保持了可接受的质量。
