“…The material elimination through magnetic fields was optimized. [87] The potential of these materials in the medical field as controlled release systems and contrast agents (CA) in magnetic resonance imaging (MRI) should also be highlighted. The study examined the significance of pore length and different morphology between MCM-41 and UVM-7 for the loading and release of a model drug like ibuprofen.…”

The use of triethanolamine in the preparation of materials has been a fertile area of research during the last decades. It is used in sol‐gel synthesis because of its ability to regulate pH, act as a structure‐directing agent, and form atrane complexes with a wide variety of elements. The atranes harmonize the hydrolysis and condensation processes of inorganic species with their interaction with surfactant molecules or micelles for the obtention of homogeneous materials. This review describes the basic principles of the formation of atrane complexes and their use in material synthesis, followed by a compilation of the main examples found in the bibliography. These materials include pure and doped silicas by using micelles as porogen species (MCM‐41, SBA‐15, UVM‐7, etc.), or without using template agents (TUD‐1, UVM‐11, etc.), non‐silica oxides (Al2O3, TiO2, ZrO2, etc.), mesoporous phosphates and phosphonates, zeotypes (zeolites, aluminophosphates or silicoaluminophosphates, and layered double hydroxides. The atrane route shows a versatile approach for the preparation of these materials with up to three elements simultaneously. The focus of the review centers on the synthesis of the materials and the discussion of their main applications. These examples enrich with a discussion about the future perspective of the topic.

“…It is well known that enzymatic browning is one of the most important challenges in the industrial minimal processing of selected fruit and vegetable products (Es‐Safi et al., 2003). The polyphenol oxidase (PPO) mediating the enzymatic reactions leads to significant color changes, whereas the oxidation of polyphenols negatively affects taste, flavor, and nutritional value ( Muñoz‐Pina et al., 2022). PPO (EC 1.14.18.1) is a copper‐containing enzyme belonging to the oxidoreductase family, which has the ability to catalyze the oxidation of monophenols to o ‐quinones, followed by a nonenzymatic polymerization of quinones, leading to melanoidin pigments, which cause a color shift toward reddish–brownish (Kanteev et al., 2015).…”

“…Apple ( Malus domestica ) is the third most cultivated fruit worldwide, with a production of around 87 million tons in 2022, whereas the most important part of total production is used for apple juice production (Bortolini et al., 2020). Due to the high polyphenol content, apple is prone to enzymatic browning (Martino et al., 2019), causing consumer rejection and leading to high amounts of food waste and economic losses for the juice industry (Muñoz‐Pina et al., 2022). In general, at the industrial level, different physical and chemical‐based methods to prevent enzymatic browning are used (Silva & Sulaiman, 2019).…”

“…Therefore, the most widely used physical‐based method is heat processing, which allows enzyme inactivation but significantly affects the biological and nutritional value of products, by the degradation of biologically active compounds and thermosensitive nutrients (Queiroz et al., 2008). A common practice is the chemical inhibition of PPO activity, by using natural and synthetic inhibitors, such as sulfites or citric acid and ascorbic acid, due to their lower cost, manageability, and minimal alteration of the bioactive compounds (Muñoz‐Pina et al., 2022). However, the use of chemical inhibitors is limited, due to their negative impact on taste and potentially allergenic of sulfites.…”

In this study, a comprehensive approach to advance the inhibitory effect of Hibiscus sabdariffa extract on apple polyphenol oxidase (PPO) was performed. PPO was extracted, purified, and characterized for optimal activity, whereas response surface methodology generated a quadratic polynomial model to fit the experimental results for hibiscus extraction. The optimum conditions allowed to predict a maximum recovery of anthocyanins (256.11 mg delphinidin‐3‐O‐glucoside/g), with a validated value of 272.87 mg delphinidin‐3‐O‐glucoside/g dry weight (DW). The chromatographic methods highlighted the presence of gallic acid (36,812.90 µg/g DW extract), myricetin (141,933.84 µg/g DW extract), caffeic acid (101,394.07 µg/g DW extract), sinapic acid (1157.46 µg/g DW extract), kaempferol (2136.76 µg/g DW extract), and delphinidin 3‐O‐β‐d‐glucoside (226,367.08 µg/g DW extract). The inactivation of PPO followed a first‐order kinetic model. A temperature‐mediated flexible fit between PPO and anthocyanins was suggested, whereas the molecular docking tests indicated that PPO is a good receptor for cafestol, gallic acid, and catechin, involving hydrophobic and hydrogen bond interactions.Practical ApplicationIt is well known that enzymatic browning is one of the most important challenges in the industrial minimal processing of selected fruit and vegetable products. Novel inhibitors for polyphenol oxidase are proposed in this study by using an anthocyanin‐enriched extract from Hibiscus sabdariffa L. Based on our results, combining the chemical effect of phytochemicals from hibiscus extract with different functional groups with minimal heating could be an interesting approach for the development of a new strategy to inhibit apple polyphenol oxidase.
