Structure and surface properties of ozone-conjugated octenyl succinic anhydride modified waxy rice starch: Towards high-stable Pickering emulsion.

In the present work, a dual-modified waxy rice starch (OOWRS) fabricated with OSA and ozone was successfully used to stabilize the O/W Pickering emulsion. The molecular structure, surface properties, and underlying stabilizing mechanism were systematically investigated. The results showed that oxidation occurring on the surface of OSA-modified waxy rice starch (OSAWRS) resulted in the presence of indentations and cracks.

Konjac glucomannan-assisted curcumin alleviated dextran sulfate sodium-induced mice colitis regulating immune response and maintaining intestinal barrier integrity.

Curcumin has been proven to be an effective strategy for reducing inflammatory responses. However, low bioavailability and instability at the physiological pH have limited its anti-inflammatory activity in ulcerative colitis patients. In the present study, a complex of curcumin and konjac glucomannan (KGM) effectively inhibited intestinal inflammation and this effect was associated with KGM degradation degrees.

seed polysaccharides attenuate inflammation-induced intestinal epithelial barrier dysfunction in a Caco-2 and RAW264.7 macrophage co-culture model by inhibiting the NF-κB/MLCK pathway.

The intestinal barrier dysfunction associated with chronic inflammation is a major health concern. This work aimed to investigate the protective effect and molecular mechanism of seed polysaccharide fraction (SMSP2) on inflammation-induced barrier dysfunction using Caco-2 cells and RAW264.7 macrophage co-culture model.

Beyond particle stabilization of emulsions and foams: Proteins in liquid-liquid and liquid-gas interfaces.

In the early 20th century, Pickering and Ramsden revealed that solid particles could be utilized as emulsion stabilizers. Later, it was shown that particles can be used to aid in stablilization of foam as well. Differentiated from the emulsions/foams constructed by using surfactant agents, particle-stabilization offers significant advantages, such as better interfacial stability, non-toxicity, and less sensitive to environmental influences.

Evaluation of the effect of prebiotic sesame candies on loperamide-induced constipation in mice.

Constipation is one of the most common gastrointestinal tract symptoms. In this study, prebiotic sesame sugar (PSC) was prepared from isomalto-oligosaccharide, konjac glucomannan and sesame, and the relieving effect of PSC on constipation induced by loperamide was explored. The results showed that PSC treatment profoundly improved the defecation function and boosted intestinal motility.

Preparation and characterization of konjac glucomannan (KGM) and deacetylated KGM (Da-KGM) obtained by sonication.

Background: Konjac glucomannan (KGM) has been widely applied in the food industry as a thickening and gelation agent because of its unique colloidal properties of viscosity enhancement and gelling ability. The current study aimed to prepare and characterize KGM and deacetylated KGM (Da-KGM) samples obtained by sonication in neutral and alkali ethanol-water solutions.

Results: The results showed that the deacetylation degree (DD) of Da-KGM increased exponentially with alkali concentration.

Probiotic Supplements: Their Strategies in the Therapeutic and Prophylactic of Human Life-Threatening Diseases.

Chronic diseases and viral infections have threatened human life over the ages and constitute the main reason for increasing death globally. The rising burden of these diseases extends to negatively affecting the economy and trading globally, as well as daily life, which requires inexpensive, novel, and safe therapeutics. Therefore, scientists have paid close attention to probiotics as safe remedies to combat these morbidities owing to their health benefits and biotherapeutic effects.

Role of green tea nanoparticles in process of tea cream formation - A new perspective.

Green tea nanoparticles (gTNPs) are considered as the precursors of tea cream, while the role of gTNPs in the process of tea cream formation remains obscure. This study indicated that gTNPs could be coated with epigallocatechin gallate (EGCG)-caffeine (CAF) complexes to form a ternary aggregate participating in tea cream formation. First, the ζ-potentials of gTNPs and EGCG-CAF complexes were adjusted by charge screening.

Encapsulation of tangeretin in PVA/PAA crosslinking electrospun fibers by emulsion-electrospinning: Morphology characterization, slow-release, and antioxidant activity assessment.

In this work, water-resistant poly (vinyl alcohol) (PVA)/poly (acrylic acid) (PAA) electrospun fibers encapsulating tangeretin (Tan) were fabricated by emulsion-electrospinning. To optimize the electrospinning condition, the size and morphology of electrospun fibers were characterized by dynamic light scattering (DLS), optical light microscope, fluorescence microscopy, and scanning electron microscopy (SEM), respectively. The optimized initial concentration of PVA/PAA was 10% (w/w) with a mass ratio of 3:7.

The noncovalent conjugations of bovine serum albumin with three structurally different phytosterols exerted antiglycation effects: A study with AGEs-inhibition, multispectral, and docking investigations.

The antiglycation effects of three structurally different phytosterols (PS) including stigmasterol, β-sitosterol, and γ-oryzanol on bovine serum albumin (BSA) were deeply studied in a BSA-glucose model by measuring the glycoxidation-based products, SDS-PAGE intensity, free lysine, and their fluorescence microscopy clicks. For the first time, the underlying mechanisms of the antiglycation effects of PS were wholly elucidated by measuring their interaction ability with BSA and their antiradical activity during the glycation reactions. The results showed that PS could partially inhibit the formation of advance glycation end products, block some of the lysyl residues of BSA (Lys127, 357, 434, and 524), prevent the glucose-BAS bonding, and their disaggregation effects on the glycated BSA.

Characteristic of interaction mechanism between β-lactoglobulin and nobiletin: A multi-spectroscopic, thermodynamics methods and docking study.

Nobiletin (Nob) is a major component among the most reported polymethoxyflavones (PMFs), which possesses multiple efficacious healthcare activities. Owing to its high melting point and poor water solubility, the oral bioavailability of Nob needs to be improved via loading Nob on carriers. To take full advantage of Nob, the interaction mechanism between Nob and vehicles should be clarified.
