This study developed a postbiotic fermentation solution for fresh oyster preservation with the use of food waste soy whey. Lactiplantibacillus plantarum 299V was able to proliferate in soy whey within 24 h without any supplementation. Pacific oysters (Magallana gigas) were immersed in the postbiotic fermentation solution and stored at 4 °C for 12 d...

Multifunctional intelligent indication labels tend to prolong the quality guarantee period and monitor the freshness of food. In this study, indication labels were prepared with carboxymethyl chitosan (CMCS) and pectin as substrate, and porous microspheres loaded with anthocyanins (ACN@PGMs) as indicators and antioxidant as well as clove essential...

Background α‐l‐Fucose confers unique functions for fucose‐containing biomolecules such as human milk oligosaccharides. α‐l‐Fucosidases can serve as desirable tools in the application of fucosylated saccharides. Discovering novel α‐l‐fucosidases and elucidating their enzyme properties are always worthy tasks. Results A GH95 family α‐l‐fucosidase na...

Customers are increasingly opting for ready-to-eat and easy-to-prepare food products, such as cooked crayfish. It is highly valued for its unique taste, tender meat, and nutritional properties. Therefore, we conducted an investigation into its quality parameters over an 8-week period at − 20 • C. Parameters such as water distribution, oxidation rea...

Alginate is a commercially important polysaccharide composed of mannuronic acid and its C5 differential isomer guluronic acid. Comprehensive research on alginate and alginate lyases requires efficient and precise analytical methods for alginate oligosaccharides. In this research, high-performance anion exchange chromatography (HPAEC) in parallel wi...

Astaxanthin (AST) is a natural marine carotenoid with a variety of biological activities. This study aimed to demonstrate the possible mechanisms by which AST improves skeletal muscle atrophy in cancer cachexia. In this study, the effects of different doses of AST (30 mg/kg b.w., 60 mg/kg b.w. and 120 mg/kg b.w.) on skeletal muscle functions were e...

Microplastics have been an emerging threat to filtering species and the ingestion and impacts of microplastics on oysters are a cause for concern. However, much remains unknown about the effects of microplastics on flavor-related biomarkers in oysters. Herein, a laboratory microplastic exposure with concentrations of 1, 10, and 100 mg/L for 15 days...

Gangliosides play an imperative role in cell signaling, neuronal recovery, apoptosis, and other physiological processes. For example, GM3 can regulate hypothalamic leptin resistance and control energy homeostasis, GD3 can mediate cell proliferation and differentiation and induce apoptosis, and GQ1b can stimulate neurogenesis. Therefore, the present...

Sea cucumber intestines are considered a valuable resource in the sea cucumber processing industry due to their balanced amino acid composition. Studies have reported that peptides rich in glutamate and branched‐chain amino acids have anti‐fatigue properties. However, the function of the sea cucumber intestine in reducing exercise‐induced fatigue r...

λ-Carrageenan is a highly sulfated polysaccharide alternating of 1,4-O-α-D-galactopyranose-2,6-sulfate (D2S,6S) and 1,3-O-β-D-galactopyranose-2-sulfate (G2S). λ-Carrageenases are desirable tools for λ-carrageenan degradation. Based on the genome mining, a novel λ-carrageenase Cgl150A_Wa was cloned from the bacterium Wenyingzhuangia aestuarii and ex...

Astaxanthin supplementation altered the amino acid metabolism in tumor-bearing mice by modulating intestinal flora, thereby reducing the rate of skeletal muscle atrophy in tumor-bearing mice undergoing treatment.

The current study aimed to evaluate the proximate composition and quality properties of eight Egyptian sea cucumbers (Bohadschia argus, H. arguinensis, H. mammata, H. poli, H. sanctori, H. tubulosa, H. forskali and Stichopus regalis) collected during October 2023 from the Mediterranean Sea in Alexandria Governorate. Proximate composition, pH value,...

Scope Hypertrophic chondrocytes have a decisive regulatory role in the process of fracture healing, and the fate of hypertrophic chondrocytes is not only apoptosis. However, the mechanism of sea cucumber ( Stichopus japonicus ) intestinal peptide (SCIP) on fracture promotion is still unclear. This study aims to investigate the effect of sea cucumbe...

BACKGROUND Agarose, mainly composed of 3,6‐anhydro‐α‐l‐galactopyranose (LA) and β‐d‐galactopyranose (G) units, is an important polysaccharide with wide applications in food, biomedical and bioengineering industries. Carbohydrate‐binding modules (CBMs) are favorable tools for the investigations of polysaccharides. Few agarose‐binding CBMs have been...

Scope The optimization of anti‐cancer drug effectiveness through dietary modifications has garnered significant attention among researchers in recent times. Astaxanthin (AST) has been identified as a safe and biologically active dietary supplement. Methods and results The tumor‐bearing mice are treated with sorafenib, along with supplementation of...

Microwave sterilization is a novel potential sterilization technology to improve food quality. An industrial microwave sterilization system was used to sterilize imitation crab meat under thermal processing intensity F0 = 1, 2, 3. The characteristics of the microwave process, such as heating rate, processing time, and C100, were calculated. In addi...

Scope Astaxanthin (AST) is ubiquitous in aquatic foods and microorganisms. The study previously finds that docosahexaenoic acid‐acylated AST monoester (AST‐DHA) improves cognitive function in Alzheimer's disease (AD), although the underlying mechanism remains unclear. Moreover, autophagy is reportedly involved in amyloid‐β (Aβ) clearance and AD pat...

This paper aims to explore the effect and mechanism of water-soluble astaxanthin succinate diester (Asta-SD) on ulcerative colitis (UC) induced by dextran sodium sulfate in zebrafish and C57BL/6J mice. Asta-SD was synthesized with hydrophilic fatty acid succinic anhydride and the hydroxyl groups at the ends of F-Asta were synthesized by esterifying...
