摘要

目的为开发具有可视化新鲜度指示功能的智能保鲜包装材料,本研究以壳聚糖为基体,构建黑枸杞花青素与纳米氧化镁共同改性的复合包装膜。方法采用溶液浇铸法制备不同花青素含量的壳聚糖复合膜并系统考察其力学性能、阻隔性能、抗氧化活性、pH响应特性及肉类新鲜度指示效果。结果纳米氧化镁的引入显著提高了复合膜的拉伸强度与穿刺性能;花青素的加入赋予了薄膜的抗氧化活性和pH响应性能。其中,花青素添加量为壳聚糖质量的40%时,复合膜在力学性能、抗氧化活性,以及颜色响应灵敏度之间表现出较好的平衡。该复合膜在不同pH条件下表现出明显的颜色变化,具有良好的pH响应能力。实际应用结果表明,复合膜在不同温度储存条件下能够反映猪肉新鲜度变化,其颜色变化与挥发性盐基氮含量和pH值具有较高相关性。结论黑枸杞花青素/壳聚糖复合膜兼具良好的力学性能、抗氧化活性、pH响应能力和可视化腐败指示功能,在智能食品保鲜包装与质量监测领域具有潜在应用价值。

Abstract

The work aims to construct a composite packaging film modified by black wolfberry anthocyanin and nano magnesium oxide with chitosan as the matrix to develop intelligent fresh-keeping packaging materials with visual freshness indication function. Chitosan composite films with different anthocyanin contents were prepared by solution casting, and their mechanical properties, barrier properties, antioxidant activity, pH response characteristics, and meat freshness indicator effect were systematically investigated. The introduction of nano magnesium oxide significantly improved the tensile strength and puncture performance of the composite film; The addition of anthocyanins endowed the film with antioxidant activity and pH responsive properties. When the amount of anthocyanin added was 40% of the mass of chitosan, the composite film exhibited a good balance between mechanical properties, antioxidant activity, and color response sensitivity. The composite film exhibited significant color changes under different pH conditions and had good pH responsiveness. The practical application results showed that the composite film could accurately reflect the changes in pork freshness under different temperature storage conditions, and its color change was highly correlated with the volatile base nitrogen content and pH value. In conclusion, the black wolfberry anthocyanin/chitosan composite film has good mechanical properties, antioxidant activity, pH response ability, and visual decay indication function, and has potential application value in the field of intelligent food preservation packaging and quality monitoring.
