In this research, modification of long-chain inulin (FXL) through phosphorylation (PFXL) to enhance its application in wheat starch (WS) and starch-based products. The impacts of PFXL on the pasting, rheology, microstructure, and retrogradation characteristics of WS were researched. The findings revealed that PFXL significantly reduced both the breakdown and setback values of WS. Additionally, the incorporation of PFXL reduced the viscoelasticity of WS paste and improved its fluidity. Scanning electron microscopy indicated that higher PFXL levels (>5 %) produced small fragments that partially covered the three-dimensional honeycomb structure of WS paste, thereby reducing water loss during short-term storage. PFXL also altered water distribution in WS gels, depending on concentration and storage duration. X-ray diffraction and Fourier-transform infrared spectroscopy suggested that PFXL effectively inhibited amylopectin recrystallization. Compared to FXL, PFXL exhibited a more pronounced ability to inhibit the aging of WS in short- and long-term storage.

The main objective of the article is to elucidate the effects of ultrasonic treatment with different ultrasonic power (0 W, 200 W, 250 W, 300 W, 400 W and 500 W) on the rheology, water distribution, sulfhydryl disulfide bond content, microstructure, and gluten properties of FXL (Long-chain inulin) dough. When the ultrasonic power is 300 W, the protein polymerization can be promoted, thus improving the gluten network. The mechanical action and cavitation induced by ultrasound changed the water distribution of FXL dough and promoted the transition from weakly bound water to tightly bound water.

Background And Aims: Alcohol Use Disorder (AUD) is a psychiatric disorder characterized notably by gut microbial dysbiosis and insufficient dietary fiber (DF) intake. This study aims to investigate the effect of DF placebo-controlled intervention in patients suffering from AUD during a three-week period of alcohol withdrawal, in order to discover microbial-derived metabolites that could be involved in metabolic and behavioral status.
Methods: A randomized, double-blind, placebo-controlled study was performed with 50 AUD patients supplemented with inulin (prebiotic DF) or maltodextrin (placebo) during 17 days.

This study aimed to examine the in vitro digestion properties and immunomodulatory effects of inulin-type fructans (ALP-1) from Arctium lappa L. on immunosuppressive mice and to explore the underlying mechanisms. The simulated gastrointestinal digestion showed that ALP-1 underwent slight degradation during gastric and intestinal fluid digestion, with most of it reaching the gut as long-chain structures.
