“…This could, in turn, reduce the photodegradation of TCS and other phenolic compounds over the materials. Furthermore, the photodegradation of TCS and the other phenolic compounds by metal oxides could produce secondary pollutants in the environment by forming other toxic intermediates or byproducts, as illustrated in Figure 6 below [ 94 ].…”

Environmental pollution remains one of the most challenging problems facing society worldwide. Much of the problem has been caused by human activities and increased usage of various useful chemical agents that inadvertently find their way into the environment. Triclosan (TCS) and related phenolic compounds and derivatives belong to one class of such chemical agents. In this work, we provide a mini review of these emerging pollutants and an outlook on the state-of-the-art in nanostructured adsorbents and photocatalysts, especially nanostructured materials, that are being developed to address the problems associated with these environmental pollutants worldwide. Of note, the unique properties, structures, and compositions of mesoporous nanomaterials for the removal and decontamination of phenolic compounds and derivatives are discussed. These materials have a great ability to scavenge, adsorb, and even photocatalyze the decomposition of these compounds to mitigate/prevent their possible harmful effects on the environment. By designing and synthesizing them using silica and titania, which are easier to produce, effective adsorbents and photocatalysts that can mitigate the problems caused by TCS and its related phenolic derivatives in the environment could be fabricated. These topics, along with the authors’ remarks, are also discussed in this review.

“…Free radicals come basically from normal essential metabolic processes in the human body. However, they are exacerbated by external sources such as exposure to xrays, ozone, smoking, or industrial chemicals (Cheng et al, 2022). Furthermore, the human lifestyle at this fast pace also contributes to the production of radicals in the body, which makes people buy and consume their food quickly without much consideration (Lee et al, 2022).…”

All modern lifestyles such as unhealthy eating patterns and lack of exercise can trigger the accumulation of free radicals in the human body, where the human body cannot neutralize these free radicals fast enough because of the large number of free radicals that have accumulated in it. Therefore, antioxidant compounds need to be consumed to suppress free radicals. In this study, mulberry is promoted as a natural, functional, and dye source that has been explored for further applications in food and beverages. This research aims to develop natural coloring products from mulberry fruit through extraction and encapsulation processes. Furthermore, hedonic testing was also carried out to determine the panelist's preference level for jelly products using mulberry fruit dyes. Mulberry fruit is extracted, encapsulated by freeze drying method, and processed into a natural dye in jelly products. Mulberry fruit extract contains vitamin C 4.1 g/ml, anthocyanin content of 215.16 mg/L, and antioxidant activity of 73.25. Mulberry encapsulates can be used as a natural dye in jelly products. Based on hedonic testing, jelly products made from natural dyes have superior taste and texture. Further development of natural mulberry fruit encapsulated dyes needs to be done to increase solubility, color sharpness, aroma and color stability
