Currently, designing smart membranes with multifunctional effectiveness is crucial to food freshness monitoring and retention. Herein, an active colorimetric Janus bilayer membrane with directional water transport (DWT) performance is constructed by electrospinning, which comprises a hydrophilic layer of silk fibroin-bayberry anthocyanins (SF-BAs) and a hydrophobic layer of polycaprolactone-eucalyptus oil (PCL-EO). The entities of BAs and EO are well dispersed in the fiber matrix by hydrogen bonds and physical interactions, respectively. BAs endow the membrane colorimetric response and antioxidant activity, and EO contributes to the antibacterial activity while DWT performance is generated from the asymmetric wettability of the two layers. The bilayer membrane has an accumulative one-way transport index of 1077%, an overall moisture management capacity of 0.76 and a water evaporation rate of 0.48 g h −1 . Moreover, the release of BAs and EO was predominantly controlled by Fickian diffusion. As a pH-sensing indicator, PCL-EO@SF-BAs is highly sensitive to external pH stimuli and the response is reversible. In addition to freshness monitoring, PCL-EO@SF-BAs can extend the shelf-life of pork beyond 100% at 4 °C. Also, it can extend the shelf life of shrimp by approximately 70% at 25 °C with the synergistic effect of antibacterial activity and the DWT performance.

The increasing rate of hyperlipidemia has drawn great attention and natural products may play a potential role in prevention of these disorders. Chinese bayberry leaves proanthocyanidin (BLPs) with epigallocatechin-3- O -gallate (EGCG) as its terminal and major extension units is unusual in the plant kingdom. Crude, purified and ultrasound depolymerized BLPs (CBLPs, SPBLPs and UDBLPs) were prepared with the aim to investigate their hypolipidemic mechanisms. BLPs inhibited the lipase activity in vitro and reduced the accumulation of total triacylglycerols (TAG) and cholesterol induced by oleic acid in HepG2 cells. SPBLPs and UDBLPS significantly increased the phosphorylation of AMP-activated protein kinase (AMPK) and thus reduced TAG and sterols biosynthesis by inhibiting its downstream proteins, such as acetyl-CoA carboxylase, 3-hydroxy-3-methylglutaryl-CoA reductase and sterol regulatory element-binding protein. BLPs also promoted glucose consumption in oleic acid induced HepG2 cells. Overall, this study suggests the hypolipidemic property and promotion of glucose consumption of BLPs via AMPK pathway.

Acrolein (ACR) derives from the external environment and the endogenous metabolism of organisms. It has super-reactivity and can induce various diseases. We investigated the capacity of cyanidin-3-O-glucoside (C3G) and its degradants/metabolites to capture ACR during thermal processing or in vivo. Our results indicated that both C3G and its degradants, including phloroglucinaldehyde (PGA) and protocatechuic acid (PCA), could efficiently trap ACR to form adducts, such as C3G–ACR, C3G–2ACR, PGA–ACR, PGA–2ACR, PCA–ACR, and PCA–2ACR. Additionally, these adducts were detected in commercial canned red bayberry products. The adducts of C3G and its metabolites conjugated with ACR, such as C3G–ACR, C3G–2ACR, PGA–ACR, and 4-hydroxybenzoic-acid–ACR (4-HBA–ACR), were also detected in mice feces treated with C3G by oral gavage, where the adduct level was dose-dependent. A similar pattern was observed in tests on human consumption of red bayberry. In human urine, only PGA–2ACR and 4-HBA–ACR, were found, whereas C3G–ACR, C3G–2ACR, myricetin-3-O-rhamnoside–ACR (M3R–ACR), PGA–2ACR, 4-HBA–ACR and ferulic acid–ACR (FA–ACR) were detected in human feces following administration of red bayberry. Our results are the first demonstration that C3G and its metabolites can capture ACR in vitro and in vivo (mice and humans) and present a novel strategy, the development of C3G as a promising ACR inhibitor.

In this study, we used Chinese bayberry residue as the raw material to extract anthocyanins using deep eutectic solvents (DESs). We screened for an efficient ADES—betaine & citric acid (Bet-CA), and coupled it with ultrasound for the extraction of anthocyanins. We delved deeply into the relationship between the physicochemical properties of deep eutectic solvents and their extraction efficiency of anthocyanins, and studied its degradation kinetics under different temperatures and light conditions. This provides a green, efficient, and multi-stability protective strategy for the recovery of anthocyanins from plant-based by-products. The results revealed that the total anthocyanin content (TAC) extracted using HB47 was 7 times higher (7.05 mg CGE/g DW) than that extracted using the conventional acidified ethanol solvent (1.05 ± 0.05 mg CGE/g DW). Correlation analysis demonstrated a significant positive correlation ( p < 0.01) between TAC and a ⁎ . The extracts were subjected to heat treatment at different temperatures and stored different light conditions. HB47 exhibited the highest degradation rate (k = 0.1169) at 80 °C. However, it showed the greatest stability at lower temperatures, particularly at 4 °C (k = 0.0016, t ½ = 433.22 h). After 7 days of storage in darkness, the preservation rate of anthocyanins extracted by different solvent systems remained above 90 %. While the loss rate under UV light exposure reached as high as 95 %, significantly higher than that under sunlight.
