Ultrasound-assisted preparation of sweet corn cob polysaccharide selenium nanoparticles alleviates symptoms of chronic fatigue syndrome.

Chronic fatigue syndrome (CFS) is a long-term chronic condition that predisposes individuals to oxidative stress and disruption of the gut microbiota. In this study, sweet corn cob polysaccharide selenium nanoparticles (U-SCPSeNPs) with relatively small particle sizes were prepared using an ultrasound-assisted method. Transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDX), X-ray diffractometry (XRD), Fourier transform infrared spectroscopy (FTIR), and ultraviolet-visible spectroscopy (UV-Vis) were used to characterize the U-SCPSeNPs and determine the monosaccharide composition of the U-SCPSeNPs.

Localization and antigenicity reduction of immunodominant conformational IgE epitopes on αs1-casein.

αs1-Casein (αs1-CN) is the major allergen in cow milk; however, the understanding of its conformational epitopes remains limited due to the absence of a well-defined three-dimensional structure, which has impeded efforts to effectively reduce its antigenicity. This study employed molecular dynamics simulations (MD), ELISA, cell assays and peptidomes analysis to investigate the critical conformational epitopes of αs1-Casein. MD and immunological analyses identified a dominant conformational epitope encompassing the regions S55-E75 & Y154-T174 & F179-W199, which exhibited strong binding affinity to IgE and triggered the releasing of β-hexosaminidase, histamine and IL-6 in KU812 cells, thereby inducing allergic responses.

Authentication of indigenous Brazilian specialty canephora coffees using smartphone image analysis.

The prevention of coffee fraud through the use of digital and intelligence-based technologies is an analytical challenge because depending on the adulterant, visual inspection is unreliable in roasted and ground coffee due to the similarity in color and texture of the materials used. In this work, a 3D-printed apparatus for smartphone image acquisiton is proposed. The digital images are used to authenticate the geographical origin of indigenous canephora coffees produced at Amazon region, Brazil, against canephora coffees from Espírito Santo, Brazil, and to capture the adulteration of indigenous samples.

Exploring the Structural and Dynamic Properties of a Chimeric Glycoside Hydrolase Protein in the Presence of Calcium Ions.

GH10 xylanases and GH62 Arabinofuranosidases play key roles in the breakdown of arabinoxylans and are important tools in various industrial and biotechnological processes, such as renewable biofuel production, the paper industry, and the production of short-chain xylooligosaccharides (XOS) from plant biomass. However, the use of these enzymes in industrial settings is often limited due to their relatively low thermostability and reduced catalytic efficiency. To overcome these limitations, strategies based on enzymatic chimera construction and the use of metal ions and other cofactors have been proposed to produce new recombinant enzymes with improved catalytic activity and thermostability.

A New Strategy for Enhancing Postharvest Quality of Sweet Cherry: High-Voltage Electrostatic Field Improves the Physicochemical Properties and Fungal Community.

Sweet cherry has a short shelf life due to the occurrence of senescence and fungal infection after harvest. This study aimed to study the effects of high-voltage electrostatic field (HVEF) on the physicochemical properties and fungal composition of sweet cherry during cold storage. The experiments were conducted at 4 °C for 28 days and the quality indicators were determined every 7 days during the period of storage.

β-carotene and resveratrol loaded glycerol monostearate-based oleogels: Physicochemical characterization at low gelation concentrations.

Oleogels are semi-solid systems that can function both as replacers of trans and saturated fats and/or as carriers of lipophilic bioactive compounds. However, bioactive compounds can affect the structure of the oleogel matrix and this effect depends on the properties of such compounds. Therefore, the aim of this study was to develop oleogels loaded with β-carotene (BC) or resveratrol (R), with low concentrations of glycerol monostearate (GMS, 2-5 wt%) and sunflower oil as organic solvent.

Combining heat treatment and conjugation between guarana extract and pea protein isolate to produce O/W emulsions loaded with vitamin D.

Growing interest in plant-based materials for stabilizing food emulsions is driven by the clean-label trend. Conjugating plant proteins with phenolic compounds from plant extracts enhances their techno-functionality and allows their use as stabilizers of emulsion-based systems. This study aimed to (i) combine heat treatment (HT) and conjugation with guarana extract (GE) to improve the emulsifying ability of pea protein isolate (PPI); (ii) encapsulate vitamin D3 (VD) in PPI/GE-stabilized emulsions; (iii) evaluate the potential of these formulations in improving VD retention during storage and in vitro bioaccessibility.
