Unveiling lotus root processing under vacuum microwave: starch-malic acid interactions based on moisture, structure, and in vitro digestibility.
Food Chem

This study evaluated the effects of malic acid vacuum microwave preconditioning (MVMP) on lotus root (LR) by examining its moisture content, dielectric properties, microstructure, and starch characteristics, including modifications in starch structure and composition. Dielectric properties and LF-NMR indicated that the dielectric constant (ε') was closely associated to moisture content and state, while changes in water migration depended on microwave power and the dielectric loss factor (ε″). Increased microwave power and malic acid concentration resulted in microstructural damage (indentation and breakage of starch granules) and starch hydrolysis into smaller particles.

Egg yolk phospholipids are commercially valuable products that are beneficial to human health. Previous research on phospholipids in egg yolk mainly focuses on phosphatidyl choline (PC), phosphatidyl ethanolamine (PE), and fatty acid compositions, and neglects the esterification position and other bioactive phospholipids. This study found a total of 19 classes of phospholipids and 275 subclasses using lipidomics.

Ibuprofen, a widely used NSAID from the aryl propionic acid class, effectively relieves pain, fever, and inflammation. On prolonged use, it leads to gastrointestinal, hepatic, and renal toxicities, particularly gastrointestinal ulcers. These side effects are largely attributed to the carboxylic acid functional group common to NSAIDs.

This study aimed to evaluate the cholesterol-regulatory effects of lauric-acid-esterified octacosanol (LEO) and oleic-acid-esterified octacosanol (OEO) compared to their unmodified counterparts and to investigate the underlying mechanisms by partially substituting the fat content in obese C57BL/6J mice induced with a high-fat diet (HFD). Rice bran oil and coconut oil were also investigated as they are rich in oleic acid and lauric acid, respectively. The results showed that all supplemented groups significantly inhibited weight gain induced by the HFD, but the groups treated with esterified octacosanol exhibited a more pronounced effect.

January 2025
Institute of Mathematics, Henan Academy of Sciences, Zhengzhou, 450046, China.
This study examines the behavior of the Casson nanofluid bioconvection flow around a spinning disc under various influences, including gyrotactic microorganisms, multiple slips, and thermal radiation. Notably, it accounts for the reversible nature of the flow and incorporates the esterification process. The aim of this study is to investigate the influence of reversible chemical reactions on the flow behavior of a Casson nanofluid in the presence of bioconvective microorganisms over a spinning disc.
