“…Anthocyanins stabilized by clays or clay minerals have provided an efficient alternative in the manufacture of intelligent, active packaging, some to prolong the shelf life of the food, others improving properties or inhibiting microorganisms [110][111][112][113][114][115]. One of these works studied the structural, morphological, thermal, optical, hygroscopic, mechanical properties, and pH sensitivity of films based on anthocyanin molecules from red cabbage and sepiolite as functional additives [110].…”

In recent years, anthocyanins, natural dyes, have promoted great scientific and technological interest. Their intrinsic antioxidant properties and health benefits make them ideal representatives of natural dyes as replacements for synthetic dyes. However, their instability can limit their use. A promising strategy to increase the color stability of anthocyanins is their interaction with clay minerals structures. Clay minerals have characteristics favorable to the stabilization of natural dyes, such as adsorption capacity, good surface chemistry, ion exchange capacity, abundance, non-toxicity, and environmental compatibility. This review summarizes relevant works that present different clays or clay minerals as robust inorganic matrices for incorporation, improved stability, and increased resistance against the thermal- and photodegradation of anthocyanins. In addition, several authors propose different applications for the formed anthocyanin-based hybrids.

In recent years, consumers have become more concerned about the freshness and safety of packaged food items with their shelf life and taste. Innovation in food packaging continuously evolves with various techniques, which improve or indicate the quality of the product throughout the supply chain. This review highlights the different packaging strategies for enhancing the freshness of various food products and proclaims an alternative to conventional food packaging systems. Also, this article emphasizes assorted packaging components for the safety of food products, implicating fresh and quality products for consumer health. Such packaging systems provide information on various concepts, including indicators, sensors, scavengers, absorbers and other smart integrated techniques and their application in food products. Moreover, this review highlights the need for exploration in toxicology and migration studies for industrial application and consumer health safety.

“…The change in pH color in anthocyanins is caused by a change in the structure of anthocyanins from a quinonoidal form to a carbinol form (Ifadah, Wiratara, & Afgani, 2022). A change in structure to a quinonoidal shape will lead to a decrease in the blue color (Raji et al, 2022;Wiyantoko & Astuti, 2020). Here is a picture of changes in the structure of anthocyanins based on the pH value.…”

The acid-base titration experiments at Senior High Schools typically use phenolphthalein and methyl orange indicators, which are relatively expensive and harmful to the environment. One of the plants containing anthocyanin pigments is boat lily (Rhoeo spathaceae (Sw.) Stearn) leaves. The research aims to determine the potential analysis of boat lily leaf extract as an alternative indicator used in chemistry learning in titration acid-base learning. The type of research used in this study is descriptive qualitative. Based on the research and discussion results, the pedagogical aspects carried out by chemistry teachers obtained results that using boat lily leaf extract indicators in acid-base titration in the acid-base chapter is appropriate and meets pedagogical terms to be applied by chemistry teachers. A review of chemistry teachers, laboratory employees, and students obtained results that the use of boat lily leaf extract indicators in acid-base titration in the acid-base chapter can be approved because it meets the aspects of ease to be applied in learning, understanding, and attractive to students, and ease of being provided in the laboratory. Based on the feasibility analysis of potential experiments, boat lily leaf extract is feasible based on financial aspects and shelf life resilience.
