Summary: A novel resveratrol triester derivative, RSVTR, was synthesized by combining resveratrol with trolox, exhibiting improved anti-glycation activity compared to resveratrol. RSVTR showed good chemical stability under various pHs and temperatures, with the greatest stability observed at pH 7.2 and 5 degrees C. The enhanced ability to inhibit the glycation process was attributed to RSVTR's better interaction with albumin due to increased topological polar surface area values and H-bond acceptor numbers.

Summary: Emulsions play a vital role in food science, but their application in food production is hindered by physical and oxidative stability issues. This study aims to review oxidation and oxidative stability in emulsions, covering lipid oxidation reactions, measurement methods, and strategies to enhance stability. Different types of emulsions, including conventional and uncommon ones, as well as multiple emulsions, nanoemulsions, and Pickering emulsions, are considered. The comparative approach is used to explain oxidative processes in various parent and food emulsions.

Summary: In this study, oil-in-water Pickering emulsions were prepared using Haematococcus Pluvialis protein (HPP) particles as an emulsifier. The emulsion showed high stability with an internal oil phase as high as 70% and average oil droplet size of 20 μm. The emulsion stabilized by 2.5% HPP and 70% oil phase ratio exhibited the best stability, even under acidic conditions, high ionic strength, and low or high temperatures. Additionally, the HPP-stabilized emulsion inhibited oil phase oxidation during storage due to the presence of astaxanthin (AST) in HPP.

Summary: Recent research has found that Parasutterella plays an important role in the development of type 2 diabetes and obesity. This study analyzed a European cohort and validated the results in a Canadian cohort. The findings showed that Parasutterella was positively associated with BMI and type 2 diabetes, and its abundance was related to the intake of carbohydrates. Furthermore, the study found a reduction in L-cysteine and activation of the fatty acid biosynthesis pathway, suggesting potential mechanisms for the development of type 2 diabetes and obesity.

Summary: This study found that obesity and metabolic abnormalities are more common in individuals with allergies, especially contact allergies. Contact allergies were strongly associated with hyperlipidemia and dietary intake of polyunsaturated fatty acids, while hay fever was linked to low physical activity, shorter sleep duration, and changes in gut microbiota composition. Genetic predisposition to hyperlipidemia was found to be associated with both contact allergies and hay fever.

Summary: Engineered fibril solutions from whey protein beta-lactoglobulin containing amyloid and non-amyloid fractions exhibit improved foaming capacity due to the synergistic interactions at the air-water interface. The non-amyloid fraction shows faster migration and adsorption, while the amyloid fraction has higher surface hydrophobicity, promoting attraction between fibrils. The incorporation of non-amyloid fraction increases the density and stability of the fibrillar film. Only small amounts of amyloid aggregates are required to stabilize foams due to the interplay between amyloid and non-amyloid proteins at the air-water interface.

Summary: The role of microglia cells in neurodegenerative diseases has been increasingly recognized. Activation of microglia cells is believed to be involved in the progression of diseases like Alzheimer's or Parkinson's disease. In this study, the researchers investigated the effects of the natural antioxidant resveratrol on human microglia cells. They found that resveratrol reduced inflammation, increased the release of insulin-like growth factor 1, decreased glucose uptake, lowered mitochondrial activity, and attenuated cellular metabolism in microglia cells. The study focused on changes in metabolism without any external stressors and demonstrated the potential protective effects of resveratrol against neuroinflammation.

Summary: The non-covalent interactions between phenolics and proteins are difficult to identify, leading to contradictory results in the literature. In this study, we use advanced methods to clarify the interactions between tea phenolics (EGCG, epicatechin, and gallic acid) and whey protein ll-lactoglobulin. The results show that all rings of EGCG can interact with native ll-lactoglobulin, indicating a multidentate binding. However, specific interactions were found for epicatechin only at higher protein:epicatechin molar ratios, and no evidence of interaction was found for gallic acid. Therefore, gallic acid and epicatechin can be added to native BLG without causing modification.

Summary: In this study, a family of (Fe4L6)-L-II spin-crossover cages based on 2,2'-pyridylbenzimidazoles was reported, and it was found that subtle ligand modifications can lower the spin crossover temperature in CD3CN by up to 186 K. Comparing different pairs of cages, it was observed that CH3 substituents on either the coordination motif or phenylene linker can lower the spin-crossover temperature by different degrees, attributed to electronic effects, steric effects, and a combination of both. The understanding of the interplay between ligand modifications from this study could contribute to the improved rational design of spin-crossover cages.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
