Article Abstract
Digestive stability of a food protein in simulated gastric fluid (SGF) continues to be considered a risk factor for allergy, even though the current science does not support this belief. Methodological shortcomings of the adaption of the SGF assay for use with purified proteins has been cited as a reason to discount results that do not conform to this belief. Missteps in conducting and interpreting the results of SGF assays are reviewed here. However, these methodological shortcomings do not invalidate the conclusion that allergenic proteins are not systematically more stable to digestion than non-allergens. The growing evidence for the dual allergen exposure hypothesis, whereby sensitization to food allergens is primarily caused by dermal and inhalation exposure to food dust, and tolerization against food allergy is primarily induced by gut exposure in food, likely explains why the digestive stability of a protein is not a risk factor for allergenicity.

This study employed high-pressure microfluidization (HPM) to facilitate the Maillard reaction between quinoa protein (QP) and dextran (DX), systematically examining the effects of various pressures on the conjugate's physicochemical properties. Fourier transform infrared spectroscopy confirmed the formation of QP-DX conjugates, characterized by a new peak at 1149 cm (covalent CN bond). Secondary and tertiary structure analyses revealed that HPM-assisted Maillard reaction partially unfolded QP molecules, enhancing conformational flexibility and interfacial properties.

Unlabelled: Lactose intolerance is defined as the inability to digest lactose due to insufficient activity of the β-galactosidase enzyme, which catalyzes the hydrolysis of lactose into glucose and galactose. This study evaluated the potential probiotic properties of isolated S8, which exhibiting high β-galactosidase activity. The strain demonstrated higher survival rate under gastrointestinal stress, with 80% and 63% viability after 3 h in simulated gastric fluid and 8 h in intestinal fluid, respectively, while retaining 60.

The anti-digestive properties of cross-linked starches are essential for the development of low glycemic foods. Dynamic digestion modeling simulates the human digestive process more accurately and is an effective tool to study its anti-enzymatic mechanism. The structural evolution characteristics and the generation rules of sugar derivatives of lotus seed cross-linked starch with low, medium, high cross-linking degree (LS-2CS, LS-6CS, LS-12CS, respectively) were studied and compared during in vitro dynamic simulation digestive system.

Background: Traditional Chinese medicine (TCM) has shown anti-tumor potential, but its molecular mechanisms remain poorly understood. This integrated bioinformatics, network pharmacology, and experimental study investigated the anti-cancer effects and mechanisms of Dendrobin A, a pharmacologically active bibenzyl compound from Dendrobium nobile, in gastric cancer (GC).
Methods: Differentially expressed genes (DEGs) were identified through analysis of the TCGA-STAD dataset.

Functional ingredient bioaccessibility is limited by instability and low solubility, thus, edible macromolecules are used to enhance delivery. This study presents a safe, sustainable method to prepare dual-network emulsion gel (CSEG). The gel is formed via Ca-induced crosslinking of sodium alginate (SA) and coffee cherry-derived polysaccharide (CCP) to enhance bioavailability.
