| 中文摘要: |
| 目的 研发一种能够可视化、无损检测羊肉新鲜度的颜色指示标签，便于消费者更加直观、准确地判断羊肉新鲜度。方法 本研究以聚乳酸为基材，玫瑰花青素为指示剂，采用静电纺丝技术制备了颜色指示标签(PLA/Ac)。通过扫描电镜、傅里叶红外光谱、氨敏感性、湿度稳定性、温度稳定性和可重复性对PLA/Ac颜色指示标签进行表征，并验证PLA/Ac颜色指示标签对羊肉新鲜度的检测效果。结果 表征结果显示，PLA/Ac颜色指示标签具有均匀分布的纺锤体结构，平均纤维直径为541.96 nm，并成功负载玫瑰花青素。此外，PLA/Ac颜色指示标签还具有良好的氨敏感性、湿度稳定性、温度稳定性和可重复性。应用结果显示，羊肉在25 ℃贮藏期间香气轮廓发生变化，酸味逐渐下降，苦味逐渐上升，咸味和鲜味则呈现出先升后降的变化趋势。当羊肉在25 ℃贮藏48 h后，总挥发性盐基氮值和菌落总数超标，此时PLA/Ac颜色指示标签的颜色由粉色变为灰色。结论 PLA/Ac颜色指示标签在可视化、无损检测羊肉新鲜度领域具有良好的应用前景，对保障消费者健康和促进行业发展具有积极作用。 |

| The work aims to develop a color indicator label that can visually and non-destructively test the freshness of mutton so that consumers can determine the freshness of mutton more intuitively and accurately. In this study, an electrostatic spinning technique was used to prepare a color indicator label (PLA/Ac) with polylactic acid as the base material and rose anthocyanin as the indicator. The PLA/Ac, color indicator label, was characterized by scanning electron microscopy (SEM), Fourier infrared spectroscopy (FTIR), ammonia sensitivity, humidity stability, temperature stability, and reproducibility. The PLA/Ac color indicator label, was verified for the detection of freshness in mutton. Characterization results showed that PLA/Ac color indicator label had a uniformly distributed spindle structure with an average fiber diameter of 541.96 nm and was successfully loaded with rose anthocyanins. In addition, the PLA/Ac color indicator label had good ammonia sensitivity, humidity stability, temperature stability, and reproducibility. The application results showed that the aroma profile of mutton changed during storage at 25 °C, with sourness gradually decreasing, bitterness increasing, and salty and fresh flavors increasing and then decreasing. After the mutton was stored at 25 °C for 48 hours, the total volatile saline nitrogen value and total colony count exceeded the standard. At this time, the color of the PLA/Ac color indicator label changed from pink to gray. The PLA/Ac color indicator label has a good potential for application in the field of visualization and non-destructive testing of mutton freshness, which has a positive effect on safeguarding consumer health and promoting the development of the industry. |
