“…As seen in Figure 7 , the PVA/CNC film revealed poor antioxidant activity due to the lack of effective antioxidant components, while the scavenging capability of PVA/CNC films on the DPPH and ABTS radical were significantly enhanced by PPA addition ( p < 0.05). Potent antioxidant activity was related to PPA, which comprised positively charged compounds (flavylium cations) at the oxygen atom of the C-ring of the flavonoid skeleton that would promote the transfer of hydrogen atoms for radical inhibition [ 46 ]. A significantly higher DPPH radical scavenging ability of 91.43% and relatively higher ABTS radical scavenging ability of 92.95% were found in 5 mg/mL of the PVA/CNC-PPA film.…”

“…The reason might be that DPPH radicals are more sensitive to the reaction environment; small changes in solvent, pH, or temperature might have a more significant effect on the measurement results, leading to higher variability. In addition, the absorbance of the DPPH radical decreased in the presence of light, and the ABTS assay was less susceptible to the interference of PPA color due to the higher wavelength used [ 46 ].…”

Anthocyanin-based smart packaging has been widely used for food freshness monitoring, but it cannot meet the requirements of smart films with antibacterial properties. This study aimed to enhance the antibacterial properties of intelligent films by incorporating Amomum tsao-ko essential oil (AEO) for mantis shrimp spoilage tracking and keeping the product fresh. A smart film was designed by introducing AEO and purple potato anthocyanin (PPA) to a polyvinyl alcohol/cellulose nanocrystal (PVA/CNC) polymer matrix. Our findings revealed that APP and AEO imparted the smart film with a favorable oxygen barrier, UV protection, mechanical properties, and antioxidant and pH/NH3-sensitive functions. Interestingly, the PVA/CNC-AEO-PPA film achieved 45.41% and 48.25% bactericidal efficacy against S. putrefaciens and V. parahaemolyticus, respectively. Furthermore, a visual observation confirmed that the target film (PVA/CNC-AEO-PPA) changed color significantly during mantis shrimp spoilage: rose red—light red—pink—light gray—dark gray. Meanwhile, the PVA/CNC-AEO-PPA film retarded the quality deterioration of the mantis shrimp effectively. The PVA/CNC-AEO-PPA film shows great application potential in mantis shrimp preservation and freshness monitoring; it is expected to become a rapid sensor for detecting seafood quality non-destructively and a multifunctional film for better preservation of product quality.

Enantioselective synthesis, which yields one enantiomer in higher concentration or purity than the other, has transformed the production of flavonoids. Flavonoids, which are found in large quantities in nature and are known to exhibit a diverse array of physiological activities, are an ideal choice for enantioselective synthesis due to the significance of chirality in their therapeutic effects. Enantioselective synthesis is used in the medicinal, nutraceutical, and agrochemical sectors to produce flavonoids, which are useful in the development of novel therapeutics with improved effectiveness and fewer adverse reactions. The ability to obtain specific enantiomers of flavonoids facilitates the elucidation of biochemical strategies and the relationship between structure and activity, thereby providing avenues for tailored drug design and optimization. This review highlights the critical role that enantioselective synthesis plays in achieving the full potential of flavonoids for a variety of therapeutic and non‐therapeutic applications. It also discusses the challenges and prospects of enantioselective syntheses to create relevant classes of flavonoid monomers, emphasizing their applications in the field. The review focused on the synthetic methods for fabricating native flavonoids and their analogs, highlighting the critical role that enantioselective synthesis of flavonoids plays in maximizing their therapeutic potential for enhancing human health and wellbeing.

“…Over the past decade, ultrasoundassisted extraction has been extensively documented to enhance the extraction rates of target compounds while reducing extraction time [4,15,22,31,32]. In this sense, in a recent study developed by Chua et al [33], the use of ultrasound as pre-treatment for just 30 min also enhanced the extraction of anthocyanins and phenolics from jaboticaba peels by 61% and 75%, respectively.…”

This study focuses on optimizing the ultrasound-assisted extraction (UAE) of bioactive compounds from purple-fleshed sweet potatoes (PFSP) for potential use as natural colorants. Factors such as time, temperature, and solid-to-liquid ratio were varied using a Box–Behnken Design. The optimal conditions were determined as 75 min, 70 °C, and a 1:15 m/v solid-to-liquid ratio, resulting in 18.372 mg/100 g total anthocyanin (TA) and 151.160 mg GAE/100 g total phenolic content (TPC). The validation yielded 18.822 mg/100 g for total anthocyanin and 162.174 mg GAE/100 g for total phenolic content, showing a 7% difference from predictions. UAE significantly increased TA extraction by 81% and TPC by 93% compared with the conventional method, with a notable reduction in process time from 24 h to 75 min. Additionally, three kinetic models were tested to compare extraction mechanisms, confirming the efficiency of UAE for PFSP bioactive compound recovery. This study proposes the UAE technique as a highly effective means of extracting bioactive compounds from PFSP, offering promising applications across multiple industries.
