Addressing the issue of color loss owing to the degradation of anthocyanins during storage in blueberry wine, we compared the stabilizing effect of phenolics on anthocyanins. Initially, the influences of phenolic co-pigments (catechin, epicatechin, gallic acid, sringic acid, and caffeic acid) on the main monomeric anthocyanin (malvidin-3-O-galactoside) in blueberry wine were evaluated in a model wine solution. Gallic acid showed the highest binding strength (binding constant K = 24.41 mol/L) and excellent thermal (half-life t 1/2 = 15.20 h) and light stability (half-life t 1/2 = 38.66 h) in the model wine solution, whereas epicatechin distinguished itself in oxidative stability (half-life t 1/2 = 11.37 h). In the subsequent storage, the blueberry wine containing epicatechin or gallic acid as co-pigments displayed markedly improved color stability, evidenced by intensified color enhancement and darker displacement, reduced color change, and maintenance of elevated levels of total phenolics, total flavonoids, and anthocyanins. This work may provide theoretical and practical guidance for stabilizing wine color during the storage of fermented fruit wines such as blueberry wine.

The qualities of Penaeus vannamei that are prone to spoilage have a significant impact on its economic profitability. To extend the shelf life of shrimp, this study formulated a novel composite preservative with pullulan and protoilludane sesquiterpene aryl esters (melleolides). Two melleolide compounds, namely armillarin and armillaripin, were identified using high-performance liquid chromatography-triple quadrupole time-of-flight mass spectrometry (HPLC–Q-TOF-MS/MS) analysis of the ethyl acetate extract of Floccularia luteovirens . The antibacterial activity of melleolides was investigated through the disc diffusion method, and it exhibited the most potent effect against methicillin-resistant Staphylococcus aureus (MRSA) among the tested bacteria, producing an inhibition zone diameter of 15.6 mm. The composite preservative displayed competitive inhibition of polyphenol oxidase, with an IC 50 value achieved at a melleolides content of 6.27%. Furthermore, the effects of the composite preservatives on shrimp quality were evaluated through sensory, colour, pH, TVB-N, APC, and TBARS assessments. The results indicated that S-PM8 treatment group inhibited the growth of the APC in shrimp from 8.98 log CFU/g (S–C) to 7.48 log CFU/g. The TVB-N content was maintained within 28.7 mg/100 g throughout the storage period. The content of TBARS was 0.97 mg MDA/kg at Day 12, which was significantly lower than that of the control group. Additionally, the composite preservatives substantially improved sensory scores and colour retention during storage. These findings demonstrate the potential of pullulan-melleolides composite preservative to extend the shelf life of P. vannamei .

Photochromic materials with rapid color-switching, long color retention times, and rewritability are crucial for meeting the requirements of future rewritable ink-free media. However, these requirements are challenging to satisfy simultaneously due to the inherent constraints among these features. Herein, a novel photochromic nanofiber nonwoven fabric was designed and constructed based on a conjugated organic–inorganic hybrid structure through electrospinning and hot-pressing techniques. The as-prepared fabric can change color in merely 5 s under UV irradiation and can reach saturation within 2 min. In addition, upon the introduction of a potent metal chelator, its color retention time exceeds 14 days under ambient conditions, significantly longer than that of most rewritable materials recently reported (several hours to 5 days). Moreover, the fabric exhibits high writing resolution and can be photoprinted and heat-erased for over 100 cycles while still retaining 96% of its initial reflectivity. Hydrophobic thermoplastic polyurethane provides the fabric with excellent waterproof and antifouling properties, thus preventing the composite from swelling or collecting graffiti due to moisture or dust. This work exploits a competitive approach for designing flexible, rewritable, and superior functional wearables with practical applications.

Fiber-based photochromic wearables have attracted growing attention in sustainable photo-patterning information displays, information security encryption, and optical data recording/storage. Molybdenum trioxide (MoO 3 ) is one of the key photochromic materials that possesses good photochromic performance, nevertheless, it faces considerable challenges in preparing photochromic textiles with stable, scalable, and long color-retention properties. In this work, a new kind of fiber-based photochromic wearables is designed and developed by combining cotton fabric with a MoO 3 -based self-adhesive polymer network and long chain silyl group. The prepared photochromic wearable has exhibited excellent fatigue resistance and favorable reversibility (> 40 cycles), rapid light response (reach color saturation with a UV dose of 60 kJ m −2 ), outstanding color retention capability (> 90 days), and desirable biocompatibility (cell viability > 100%). In addition, the prepared photochromic textiles could maintain a fast light response and excellent color retention even after experiencing repeated washing (20 cycles). Moreover, the photo-patterning photochromic wearables are verified by resisting the deterioration of acid solution, alkali solution, and sweat (pH 2.0–9.0) as well as keeping clear patterns under sunlight irradiation. As a demonstration of the application, fiber-based photochromic wearables are made and employed for the sustainable applications of rewritable photo-patterning and information security encryption.
