CO hydrogenation to methanol using green hydrogen derived from renewable resources provides a promising method for sustainable carbon cycle but suffers from high selectivity towards byproduct CO. Here, we develop an efficient PdZn-ZnO/TiO catalyst by engineering lattice dislocation structures of TiO support. We discover that this modification orders irregularly arranged atoms in TiO to stabilize crystal lattice, and consequently weakens electronic interactions with supported active phases.

In our previous work, wheat gluten (WG) has been modified by pH-shifting treatment combined with heat to improve solubility and emulsibility. In this study, the high-soluble modified wheat gluten (M-WG) as an emulsifier in ice cream was investigated. Compared to monoglycerides (MG) and soy protein isolates (SPI), the ice cream emulsion prepared with M-WG exhibited smaller droplet sizes and a more consistent dispersion.

Pasteurization is an effective sterilization technique for the treatment of liquid egg white (LEW), but the pasteurization temperature is generally limited because increased temperature can lead to aggregation of the proteins and affect their processing properties. In this study, phosphorylation modification was used to increase the thermal stability and pasteurization temperature of LEW, aiming to enhance the pasteurization sterilizing effect. The FT-IR results showed that the phosphate groups were successfully grafted into protein molecules, improving the order degree of protein molecules.

The popularity of plant-based meat alternatives (PBMAs) has sparked a contentious debate about their influence on intestinal homeostasis compared to traditional animal-based meats. This study aims to explore the changes in gut microbial metabolites (GMMs) induced by the gut microbiota on different digested patties: beef meat and pea-protein PBMA. After digesting in vitro, untargeted metabolomics revealed 32 annotated metabolites, such as carnitine and acylcarnitines correlated with beef meat, and 45 annotated metabolites, like triterpenoids and lignans, linked to our PBMA.

Tumor-specific T cells are crucial in anti-tumor immunity and act as targets for cancer immunotherapies. However, these cells are numerically scarce and functionally exhausted in the tumor microenvironment (TME), leading to inefficacious immunotherapies in most patients with cancer. By contrast, emerging evidence suggested that tumor-irrelevant bystander T (T) cells are abundant and preserve functional memory properties in the TME.

Real-time dynamic imaging of immunoactivation-related cytokines is crucial for evaluating the efficacy of immune checkpoint blockade therapy and optimizing the treatment regimen. We introduce herein a spatiotemporally controlled nanodevice that allows photoactivated imaging of interferon-gamma (IFN-γ) secretion from T cells and . The nanodevice is constructed by rational engineering of an aptamer-embedded, UV-cleavable PC-DNA probe and further integration with upconversion nanoparticles- and CRISPR-Cas12a-enhanced fluorescence systems.

Due to the serious bacterial infection of skin and the waste of petroleum-based materials, there is an urgent need to develop natural biodegradable wound dressings with high antibacterial activity. Phosvitin (PSV) has shown its natural antioxidant and antibacterial properties, making it an excellent material for preparing wound healing dressings. In this study, we investigated the effect of magnetic field on the preparation of PSV-Microcrystalline Cellulose (MCC) composite hydrogels in 1-Allyl-3-methylimidazolium chloride (AmimCl) system.

Background: Wheat gluten protein (WGP) is poorly soluble and does not easily form fibrous structures. The meat analogues prepared from it have an unsatisfactory texture and poor water-holding capacity (WHC). Our previous work indicated that pH-shifting combined with heat treatment can significantly improve the solubility and emulsifiability of WGP.

Article Synopsis
  • - The study explores how different fermentation times (0, 3, 6, and 9 hours) of egg yolk affect the physicochemical properties, sensory quality, and storage stability of mayonnaise.
  • - Mayonnaise made with fermented egg yolk showed lower particle size and higher emulsion stability compared to the control, along with improved texture, color, and flavor.
  • - Results indicated that mayonnaise with 3-hour fermented egg yolk received the highest sensory ratings and maintained a more stable appearance after 30 days of storage, suggesting fermentation is beneficial for improving its quality and shelf life.

Plant protein films are a research hotpot in the current food packaging field for their renewable and bio-compatibility, and further improving the physicochemical properties of plant protein films in combination with biodegradable materials is of great significance. In this study, we selected cellulose nanocrystals (CNC) to modify the protein films with soybean protein isolate (SPI), wheat gluten protein (WGP), and Zein, and the physicochemical properties were studied. The results showed that the hardness and opacity of Zein-based films decreased by 16.

Phosvitin (PSV) is considered as a good emulsifier, although it has a low proportion of hydrophobic regions and steric hindrance. Wheat gluten (WG) possesses excellent hydrophobicity and macromolecular network structure. In this work, WG was subjected to a series of NaSO solution, followed by cross-linking with PSV under transglutaminase (TGase) catalyzation.

Systemic inflammation will cause an imbalance in the steady state of the gut-brain axis. Phosphatidylcholine (PC) is a phospholipid found in egg yolk that has anti-inflammatory and antioxidant properties. The present research proved that PC supplementation (60 mg/kg body weight) for 35 days prevented inflammatory responses and behavioral disturbances in lipopolysaccharide (LPS)-induced mice.

Phosvitin phosphopeptides (PPP) effectively enhanced calcium bioavailability via inhibiting calcium-phosphate deposition. It is difficult to hydrolyze native phosvitin (PSV) to release PPP due to its compact structure. Polysaccharide conjugation could improve the biofunctional properties of proteins via altering their structures.
