Abstract

This study developed an innovative colorimetric film by incorporating 1-butyl-3-methylimidazolium chloride (BmimCl) in a composite matrix containing red cabbage anthocyanins extract (RCAE), ferulic acid (FA), gellan gum (GG), and potato starch (PS) for real-time grass carp freshness detection. A comprehensive analysis was conducted on the rheological characteristics of film-forming solutions, mechanical properties, hydrophobicity, opacity, characterization of structure, sensitivity, and color stability of smart film. Significantly, the introduction of BmimCl led to multifaceted enhancements in film performance. The findings indicated that the flexibility of films added with BmimCl was enhanced and the elongation at break (EAB) was increased from 20.34 % to 28.36 %. The surface of films was smoother and denser, and the surface roughness was reduced from 1.7 μm to 1.2 μm. The peak intensities of the XRD and FT-IR patterns of films changed, indicating the formation of hydrogen bonds between BmimCl and film substrates. The GGPS-R-FA-B4 film presented the most pronounced color change in different pH environments and the most sensitive response to the variation of ammonia concentration in the environment. The color of GGPS-R-FA-B4 film exhibited a strong correlation with the quality change of fish, which could be used to distinguish the freshness, sub-freshness, and spoilage of grass carp. This study provided an effective method to enhance the accuracy and sensitivity of smart films for monitoring food freshness.

一种以1-丁基-3-甲基咪唑氯为调谐器的比色增强和高ph响应智能薄膜，用于监测草鱼的新鲜度

本研究将1-丁基-3-甲基咪唑氯（BmimCl）掺入含有红甘蓝花青素提取物（RCAE）、阿魏酸（FA）、结冷胶（GG）和马铃薯淀粉（PS）的复合基质中，开发了一种新型比色膜，用于实时检测草鱼的新鲜度。综合分析了成膜液的流变特性、力学性能、疏水性、不透明度、结构表征、灵敏度和颜色稳定性。值得注意的是，BmimCl的引入导致了胶片性能的多方面增强。结果表明，加入BmimCl后，薄膜的柔韧性增强，断裂伸长率（EAB）由20.34%提高到28.36%。薄膜表面更加光滑致密，表面粗糙度从1.7 μm降低到1.2 μm。薄膜的XRD和FT-IR谱峰强度发生了变化，表明BmimCl与薄膜衬底之间形成了氢键。GGPS-R-FA-B4膜在不同pH环境下颜色变化最明显，对环境中氨浓度变化的响应最敏感。GGPS-R-FA-B4膜的颜色与鱼的品质变化有较强的相关性，可用于区分草鱼的新鲜度、亚新鲜度和变质度。本研究为提高智能薄膜监测食品新鲜度的准确性和灵敏度提供了一种有效的方法。

期刊介绍： Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied. Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media. The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
