Article Abstract
This study investigated the effects of differential modification of the structural flexibility of egg white protein (EWP) by different polyphenols, which in turn enhanced the oral processing properties and fat perception of EWP-based double network emulsion gel (DNEG). After modification with polyphenols, the skeleton of gel became more delicate, which improved the hardness and cohesion of DNEG. This transformation was attributed to the shift from hydrophobic interactions to hydrogen and covalent bonds. Notably, proanthocyanidins (PC) effect was better, which resulted in a 58.5 % increase in oral wettability and a more appropriate oral tribological performance (0.53). Besides, DNEG increased fatty taste perception via the "ball bearing" effect as a fat substitute in sausage. In summary, this study could enhance the refined design of gels and provide ideas for improving the fatty taste of low-fat, healthy foods.
Background: Oral treatment with the exogenous ketone body 3-hydroxybutyrate improves cardiac function in patients with heart failure with reduced ejection fraction, but ketosis is limited to 3 to 4 hours. Treatment with (R)-1,3-butanediol (BD) provides prolonged ketosis in healthy controls, but the hemodynamic and metabolic profile is unexplored in patients with heart failure with reduced ejection fraction.
Methods And Results: This was a randomized, single-blind, placebo-controlled, crossover study.

Crackers are bakery products that have shown an increase in consumption. One way to make crackers more nutritious is to add bioactive compounds, such as chia oil which is rich in polyunsaturated fatty acids. As these compounds are highly unsaturated, encapsulation techniques, such as nanoemulsion, allow the addition of them in foods, guaranteeing the preservation of their properties.
Fermentation is a key process in Congou black tea, but there is limited research on the changes in flavor factors and their interrelationships during different fermentation stages under industrial production. This study applies sensory evaluation and metabolomics techniques to explore the interactions between flavors. Sensory evaluation indicated that the 4-h fermented sample exhibited the best overall performance.
The presence of food in extra virgin olive oil (EVOO) during simultaneous storage might bring additional changes to the oil's composition and quality. To investigate this matter, the influence of dried tomatoes on the oxidative and hydrolytic parameters, fatty acids, phenolic and volatile composition, antioxidant activity, pigments, and sensory attributes of EVOO during six months of simultaneous storage at room temperature (RT; 22 ± 2 °C) and +4 °C, was studied. Lower storage temperature reduced the hydrolytic and oxidative degradation of oils when dried tomatoes were immersed.

Background: Disease-related malnutrition, with or without inflammation, in older adults is currently emerging as a public health priority. The use of Foods for Special Medical Purposes, including Oral Nutritional Supplements, and supplements is crucial to support patients in achieving their nutritional needs. Therefore, this article aims to comprehensively provide an analysis of the adequacy of FSMPs in meeting the nutritional requirements of different age-related diseases and takes into account the emerging role of inflammation.
