Summary: A nanofiber film was prepared using polylactide (PLA), butterfly pea flower extract (BPA) and cinnamaldehyde (CIN) through electrospinning technique. The film exhibited prominent antioxidative, antibacterial, colorimetric and hydrophobic properties, enabling the monitoring and maintenance of beef freshness for up to 6 days at 4 degrees C. The nanofiber structure also allowed for rapid color responsiveness under acidic-alkaline atmospheres with different concentrations. Additionally, the film showed higher tensile strength than pure PLA electrospinning film, and the introduction of BPA effectively enhanced the antimicrobial ability of CIN. The film's color difference change facilitated easy detection of beef freshness, sub-freshness, and spoilage levels, making it an excellent candidate for intelligent packaging in meat sub-freshness detection.

Summary: A poly (lactic acid) (PLA) -based functional partition composite membrane (PLA/CA) containing chitosan (CS) and alizarin (AL) was designed for food packaging. The composite membrane exhibited antibacterial and pH-responsive properties, and the addition of tributyl citrate (TBC) enhanced its flexibility and transparency. The results showed that CS and AL were uniformly dispersed in the PLA matrix and had good compatibility. The composite membrane demonstrated good antioxidant activity and UV barrier performance, and exhibited high inhibitory rates against Escherichia coli and Staphylococcus aureus. The color change of the membrane could detect the freshness of food during packaging and storage.

Summary: This study presents an integrated 3D cell-based electrochemical biosensor to evaluate the neurotoxicity of organophosphorus pesticides (OPs). The sensor uses OPs to inhibit the activity of intracellular acetylcholinesterase (AChE), resulting in a decline in enzymatic hydrolysate 1-naphthol (1-N). The fluctuation of the 1-N electrochemical response is proven to be a reliable indicator for assessing OPs neurotoxicity. Gelatin methacrylate hydrogel is used as a scaffold for 3D culture of PC12 cells, while zeolite imidazolate framework67@CoAl layered double hydroxides/multi-walled carbon nanotube composites enhance the sensitivity of the screen-printed carbon electrode.

Summary: Diabetes affects one in six pregnancies, posing risks to mother and child. The effectiveness of diet and exercise in controlling dysglycemia in different populations and types of diabetes is uncertain. A systematic review and meta-analysis of 26 studies on pregnant women with gestational diabetes mellitus (GDM) found that nutritional supplements, diet, and exercise interventions could improve glycemia. However, evidence is lacking for women with pre-existing diabetes.

Summary: The effects of pulsed pressure curing on various attributes of beef were investigated in this study, including absorption of curing solution, cooking loss, moisture content, centrifugal loss, salt content, sensory attributes, texture, microstructures, and volatile compounds. The results showed that pulsed pressure curing significantly improved the efficiency and moisture content of the beef, reduced cooking loss, enhanced meat color, and improved texture compared to other curing methods. Additionally, sensory evaluations revealed that pulsed pressure curing improved the saltiness of the beef. TPA results indicated that the springiness and cohesiveness of the beef were increased, while hardness and chewiness were reduced. SEM images demonstrated that pulsed pressure curing increased the tenderness of the beef. Overall, this study highlights the advantages of pulsed pressure curing in terms of efficiency and sensory attributes of processed meat products.

Summary: High-stability bi-layer films (A-CBAL) containing anthocyanin-loaded liposomes were developed for non-destructive monitoring of shrimp freshness. Increasing the lecithin ratio improved the encapsulation efficiency of liposomes from 36.06% to 46.99%. Compared to films with free anthocyanins (A-CBA), the A-CBAL films showed lower water vapor transmission and slower exudation rate at pH 7 and pH 9. The bi-layer films successfully detected shrimp freshness through visible color changes, indicating potential applications in high-humidity environments.

Summary: This study used a combination of colorimetric sensor array (CSA) and mobile near-infrared (NIR) spectroscopy to predict the free fatty acids in wheat flour. The mid-level fusion coupled partial least squares (PLS) model showed superior data fusion results with higher correlation coefficients (RC = 0.8793), lower root mean square error of prediction (RMSEP = 6.99 mg/100 g), and higher residual predictive deviation (RPD = 2.27). The findings suggest that the NIR-CSA fusion approach can effectively predict free fatty acids in wheat flour.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
