The globalization of the food industry chain and the increasing complexity of the food supply chain present significant challenges for food authenticity and raw material processing. Food authenticity identification now extends beyond mere adulteration recognition to include quality evaluation, label compliance, traceability determination, and other quality-related aspects. Consequently, the development of high-throughput, accurate, and rapid analytical techniques is essential to meet these diversified needs.

The early intervention of precancerous lesions of gastric cancer (PLGC) is crucial for improving the survival of patients with gastric cancer. Traditional pharmaceuticals for the treatment of PLGC are limited by side effects, thus developing innovative drug carrier that are more efficient but without the undesirable side effects is required. Here, we proposed an acid-triggered mushroom-derived β-glucan carrier embedding doxorubicin (DOX) to circumvent drug cytotoxicity and synergistically alleviate PLGC based on the controlled conformational transformation.

A masticatory simulator is a mechanical device that mimics the physiological structures of the human oral cavity, chewing movement system, and functions. The advantage of this device lies in real-time tracking and analysis of food boluses within a sealed oral space, offering a direct validation platform for food experiments without constraints related to time, space, and individual variations. The degree to which the masticatory simulator simulates physiological structures reflects its efficacy in replicating oral physiological processes.

Article Synopsis
  • The study compared pectin and hydrolyzed pectin coatings as treatments to reduce acrylamide in fried potato chips.
  • Both coatings effectively reduced acrylamide levels by over 90%, with hydrolyzed pectin outperforming pectin, especially at concentrations greater than 2%.
  • Hydrolyzed pectin also provided better quality characteristics for the chips, including reduced browning and increased crispness, indicating its superior potential for application compared to regular pectin.

As prebiotics supplemented in infant formulas (IFs), galactooligosaccharides (GOSs) also have many other biological activities; however, their Maillard reaction characteristics are still unclear. We investigated the Maillard reactivity of GOSs and their effects on advanced glycation end product (AGE) formation during IF processing. The results showed that AGE and HMF formation was temperature-dependent and reached the maximum at pH 9.

Flavonols are bioactive substances in plant foods. In this study, two flavonols galangin and kaempferol were heated at 100°C for 30 min prior to assessing their effects on barrier function of rat intestinal epithelial (IEC-6) cells. Both heated and unheated flavonols (2.

Polyphenols are beneficial to human health because of their bio-activities. In this study, two flavonols quercetin and myricetin with or without heat treatment at 100 °C for 30 min were assessed for their barrier-promoting efficiency in rat intestinal epithelial (IEC-6) cells. The results indicated that the heated and unheated flavonols at dose levels of 2.

Pectin oligosaccharides (POSs) can not only be used as prebiotics to promote the growth of beneficial bacteria in the intestine but also can be used as natural food-borne antiglycation agents to inhibit the formation of advanced glycation end products (AGEs) in vitro, which is related to their structure, including molecular weight and galacturonic acid content. In this study, haw polysaccharides (HPSs) were isolated and purified, and POSs with high antiglycation activity in vitro were prepared. On this basis, the inhibitory effect of POSs on the formation of AGEs in infant formula milk powder was investigated.

Casein hydrolysates (CH) were prepared using papain and modified by the plastein reaction (CH-P) in the presence of extrinsic phenylalanine (CH-P-Phe) or tryptophan (CH-P-Trp). The in vitro protective activity of CH and its modified products against ethanol-induced damage in HHL-5 cells was investigated. The results showed that the modification by the plastein reaction reduced the amino group content of CH.

Article Synopsis
  • Two types of nuclei—homogeneous and secondary—play a role in fibril formation in whey protein concentrate (WPC), affecting how quickly and effectively amyloid fibrils form.
  • Thioflavin T fluorescence analysis showed that both types of nuclei speed up WPC fibrillation, with homogeneous nuclei resulting in more fibrils compared to secondary nuclei, which accelerated the aggregation process.
  • Although secondary nuclei led to faster aggregation rates initially and shorter gelation times for WPC, the final gel from homogeneous nuclei had a denser structure, providing better water retention.

Probiotics have been proposed as an option for the prevention of type 2 diabetes mellitus (T2DM). The objective of this study was to evaluate the hypoglycemic effects of Lactobacillus paracasei on diabetic mice and explore the possible underlying molecular mechanism. The α-glucosidase inhibitory activities of eight L.

An atrazine-degrading bacterial strain named L-6 was isolated from the sludge mixture of the sewage treatment plant by cultivating in raw water with limited nutrition and aeration and was domesticated steadily using SBR (Sequencing Batch Reactor) for two months. The degradation rate of atrazine in inorganic liquid culture medium with atrazine as the sole source of nitrogen could reach 89.2% after 96 hours.
