Abstract

A novel, sustainable time-temperature indicator (TTI) ink based on natural pigments is introduced for food freshness monitoring. The ink, composed of hydroxyethyl cellulose (HEC), Clitoria ternatea anthocyanin, and N-hydroxyphthalimide (NHPI), was applied to art paper using screen printing. The inks were characterized through FT-IR, particle size analysis, and rheological measurements, with optimal performance achieved at Clitoria ternatea anthocyanin to NHPI ratios of 9:1 and 7:1. The color change of the ink followed the Arrhenius equation, correlating with food degradation activation energies ranging from 0 to 75 kJ/mol. The ink was applied to monitor pork freshness, demonstrating high sensitivity and accuracy in tracking food quality. This TTI ink offers a cost-effective, environmentally friendly solution for food freshness assessment, with potential applications in reducing food waste and enhancing consumer confidence in food safety.

基于阴蒂蓝花瓣花青素和n -羟基邻苯二胺的时温羟乙基纤维素油墨的研制与应用。

介绍了一种基于天然色素的新型可持续性时温指示剂（TTI）油墨，用于食品新鲜度监测。将羟乙基纤维素（HEC）、阴蒂花青素和n -羟基酞酰亚胺（NHPI）组成的油墨用于丝网印刷艺术纸。通过FT-IR、粒度分析和流变学测试对油墨进行了表征，当阴蒂花青素与NHPI的比例为9:1和7:1时，油墨的性能达到最佳。油墨的颜色变化遵循Arrhenius方程，与食品降解活化能相关，范围为0 ~ 75 kJ/mol。该墨水用于监测猪肉新鲜度，在跟踪食品质量方面具有很高的灵敏度和准确性。这种TTI油墨为食品新鲜度评估提供了一种经济、环保的解决方案，在减少食物浪费和增强消费者对食品安全的信心方面具有潜在的应用前景。

期刊介绍： The International Journal of Biological Macromolecules is a well-established international journal dedicated to research on the chemical and biological aspects of natural macromolecules. Focusing on proteins, macromolecular carbohydrates, glycoproteins, proteoglycans, lignins, biological poly-acids, and nucleic acids, the journal presents the latest findings in molecular structure, properties, biological activities, interactions, modifications, and functional properties. Papers must offer new and novel insights, encompassing related model systems, structural conformational studies, theoretical developments, and analytical techniques. Each paper is required to primarily focus on at least one named biological macromolecule, reflected in the title, abstract, and text.
