“…proposed a diffusion‐type TTI consisting of a reservoir (filled with tween 20) linked to a microporous track strip ( Figure A). [ 84 ] Through diffusion of tween 20 in the strip a concentration gradient is built. When tween 20 reaches the test line made of poly‐diacetylene/silica nanocomposite (PDA/SiO 2 NC), it changes color irreversibly (from blue to red) indicating the TTI endpoint (i.e., the product deterioration time).…”

Concentration gradients are at the basis of many natural phenomena and hold great importance in human and plant biology. This basic phenomenon has inspired many material scientists to confer novel and original properties to materials with numerous biomedical and pharmaceutical applications such as drug discovery, controlled release of drugs, tissue engineering, orthopedic implants and time–temperature indicators, amongst others. While the generation of gradients in solution is well described, their incorporation in solid materials remains challenging. This study reviews concepts and methods reported to generate gradients in respective solutions and (at the surface or in) solid materials like polymer scaffolds and matrices. This article also discusses how innovative materials possessing such gradients may be applied in biomedicine and pharmacy.

“…In the diffusion‐type TTI, the endpoints alter with the position of the sign line or spot on the TTI strip. If the line is situated at a relatively long distance along the diffusion strip, it predicts a relatively long shelf life, causing a high possibility of an undesirable OP (TTI endpoints > food shelf life) and contrariwise (Suppakul, Kim, Yang, Lee, & Lee, 2018).…”

The development of smart packaging and innovation in common food packaging technology will greatly help to meet market needs, including consumer preference for "safe" foods, high-quality products and mitigate the negative environmental impacts of food packaging. In addition, consumers' tendency to use natural ingredients such as pigments and biopolymers has provided the basis for their application in the food industry, including smart food packaging. Hence, smart packaging in addition to protecting food products against environmental damage can also reveal a sign (colorimetric, chemical, electric, etc.) in real time in response to any changes in the packaging conditions and food quality. This comprehensive review emphasizes on the gas/temperature-sensitive smart films based on natural colorants and their key applications in the food packaging systems. Technological considerations associated with the natural colorantresponsive films, smart packaging, biopolymers, and importance of natural colorants versus synthetic dyes are investigated. In practice, the most common designed colorimetric indicators for monitoring gas and temperature changes and application of relevant smart films in real food models have also been discussed. Gas and time-temperature indicators provide a rapid, reliable, and online assessment and a visual indication of the food product quality level, usually through a color change, which is directly related to gas and temperature conditions during distribution and storage of relevant food products. However, future studies need to consider main points such as cost, consumers' acceptance, and confidence, regulatory aspects (i.e., labeling) and multifunctionality of smart packaging to be commercially sustainable.

“…Different kinds of food material will be stored at different temperatures; the system had the ability to detect temperature changes indirectly with the help of variation of pH of the food products, which occurred due to the improper temperature for the transportation and storage. Recently, a prototype diffusion-based TTI has been developed by Suppakul et al [47]. A polydiacetylene (PDA)/SiO 2 nanocomposite was used as the color-developing substance and loaded on the diffusion path.…”

Traditional food packaging systems cannot provide any information related to the food quality during storage to consumers. Recently, the renewable resources have been considered as starting materials for making biodegradable packaging film. A variety of food processing by-products have been utilized, either alone or in mixtures, to produce packaging films with proper properties. It shows high possibility for smart biodegradable filmmaking as well as is applicable in the food industry. In order to monitor the food quality and to reduce the food loss and waste, a new packaging technology has been increasingly developed. Smart packaging refers to packaging systems which can monitor, detect, and inform about the qualities of food in real time. Indicator is the most commonly used device, which can communicate through direct visual change, especially in color. Natural extract and synthetic color are usually added into smart packaging films. However, synthetic dyes may be harmful to the consumers' health. Thus, the use of natural extract has been increased. Smart packaging films can be applied to various types of food products in order to monitor the food quality during transportation and storage. Thus, smart packaging could be used as a nondestructive tool to detect the food quality.
