Role of dietary fiber and flaxseed oil in altering the physicochemical properties and 3D printability of cod protein composite gel

Personalized food is created for customers with specific needs by 3D printing techniques. Hence, the new research looked at the rheological characteristics of the cod protein composite gel made on different combinations of inulin/soybean dietary fiber and flaxseed oil percentages. The results revealed the CPCG's suitability for 3D printing with percentages of IN:SDF at 7:3 and 5:5 as well as 10% of flaxseed oil, wherein the gel was highly thixotropic, making it suitable for use as food ink.

Influence of Soybean Dietary Fiber on the properties of Konjac Glucomannan/κ-Carrageenan Corn Oil Composite Gel

The effects of soybean dietary fiber on konjac's gel characteristics were determined. Due to the porous gels produced by SDF in the gels, the KGM/u03ba-CA composite gel with SDF had improved water- and oil-holding capacities. SDF provided a spatial framework to KGM and u03ba-CA, it enhanced the gel's internal architecture and weakened the systems' cohesive framework, resulting in inconsistent gel structure. SDF improved the storage modulus of the mixed gels and accelerated the formation of more robust gel structures, according to the frequency sweep results. SDF improved the apparent viscosity of the mixed gel system, according to the results of steady shear rheology. The findings of this investigation provided specific guiding meaning and benchmark value for the manufacture of solid fat products simulated by SDF/KGM/u03ba-CA composite gel.

Effects of electron beam irradiation treatment on the structural and functional properties of okara insoluble dietary fiber.

Background Insoluble dietary fiber has healthful physiological benefits, including intestinal peristalsis promotion, intestinal growth, and the absorption of certain harmful chemicals. However, the greater particle size and poor water solubility of okara IDF have detrimental effects on sensory properties and functional characteristics. We then investigated that the effects of EBI doses on okara's structure and functional characteristics, as an emerging physical method. IDF's crystalline structure was destroyed by the electron beam treatment, according to the authors. Conclusions The modified okara IDF improved particle size and hydration characteristics, as well as an improvement to the IDF's bland taste and texture and storage time after supplementation into food.

Activity-based protein profiling identifies alternating activation of enzymes involved in the bifidobacterium shunt pathway or mucin degradation in the gut microbiome response to soluble dietary fiber.

Although deprivation of dietary fiber has been related to adverse health events, studies into the effects of dietary fiber on the gut microbiome have been mostly limited to compositional sequence-based analyses or use a specific microbiota not native to the host. We discovered that mice raised functional activity of many proteins, including glycoside hydrolases, polysaccharide lyases, and sugar transport proteins from various taxa. Our results are complemented by metabolomics and shotgun metagenomics studies, providing a holistic investigation into dietary fiber metabolism in the gut microbiome and showing the value of a combined ABPP-multiomics approach for characterizing the gut microbiome's response to perturbations.

The potential mechanisms of bergamot-derived dietary fiber alleviating high-fat diet-induced hyperlipidemia and obesity in rats.

DFs had dose-dependent regulatory effects against metabolic syndrome, slowed the rate of weight gain, and stifled obesity by slowing down the rate of weight gain, as well as reduced body mass index and Lee's index without impacting appetite, according to the feeding experiment. DFs significantly up-regulated the protein expression levels of LXR-1 and CYP7A1 and CYP7A1, according to the liver's Western blot results, and down-regulated the levels of SREBP-1c, FAS, ACC, and SREBP-2. These results show that DFs played an important role in lowering weight and lipid levels in liver by encouraging the decomposition and transport of lipids, as well as raising the energy consumption of brown adipose tissue. The difference in the intestinal microflora between rats fed with a regular diet and those fed on a high-fat diet was reduced by DFs' intervention, which reduced the difference in the intestinal microflora between rats fed with a normal diet and those fed on a high-fat diet. Soluble dietary fiber and total dietary fiber were shown to have improved weight loss and hypolipidemic potential in comparison to insoluble dietary fiber at the same dose.

Gut firmicutes: Relationship with dietary fiber and role in host homeostasis.

Accumulating evidence shows that dietary fiber plays a vital role in host health, but the majority of studies have focused on how gut Bacteroides influence health. We review the current evidence regarding dietary fiber degradation by gut Firmicutes' molecular mechanism and outline the communication path of the dietary fiber-to-host axis, as well as the beneficial effects of dietary fiber-induced Firmicutes and their metabolites on health in this article.

Role of dietary fiber in promoting immune health-An EAACI position paper.

Since fiber-derived metabolites are evolutionarily hardwired into the immune cell decision-making processes, genetic changes in fiber intake may be contributing to the rise in allergic and hypersensitivity disorders. In this report, we discuss the role of fiber as a diet, its effects on the microbiome, its effects on immune regulation, the benefits of targeted intervention in the prevention and management of allergic diseases.

Rice hull insoluble dietary fiber alleviated experimental colitis induced by low dose of dextran sulfate sodium in cadmium-exposed mice.

This research was conducted in the hopes of finding the protective effect of rice hull insoluble dietary fiber on Cd-promoted colitis caused by a low dose of dextran sulfate sodium. In colitis mice with Cd exposure, the administration of RHF reduced inflammation by limiting Cd accumulation and monitoring intestinal immune homeostasis. RHF could enhance mucin secretion and intestinal tightness in mice while also improving intestinal tightness. Beneficial bacteria colonization in colitis mice was also accompanied by a reduction in short-chain fatty acids, boosting RHF's potential as a prebiotic in cases of harm caused by Cd exposure in colitis mice. When the gut microbiota was depleted by antibiotics, RHF became increasingly resistant to Cd toxicity in colitis mice. We believe RHF could be used as a novel dietary supplement to combat Cd-exacerbated colitis.

Quinoa bran soluble dietary fiber ameliorates dextran sodium sulfate induced ulcerative colitis in BALB/c mice by maintaining intestinal barrier function and modulating gut microbiota.

For four weeks, ulcerative colitis mice caused by dextran sodium sulfate were fed QBSDF to clarify the effect of quinoa bran soluble dietary fiber on gut inflammation and homeostasis. QBSDF reduced DSS-induced colitis symptoms, followed by a significant reduction of colon shortening and colonic epithelial injury, according to study. In addition, the number and abundance of gut microbiota in QBSDF-fed mice were significantly higher than that of UC mice. These results demonstrated the promising promise of QBSDF as a functional food ingredient to prevent ulcerative colitis by maintaining intestinal barrier function and modulating gut microbiota.

Structural Characterization of Dietary Fiber from Different Lupin Species ( Lupinus sp.).

Whole seeds from several lupin species were characterized by dietary fiber fractions. The soluble dietary fiber fraction is dominated by homogalacturonan and rhamnogalacturonan type I, with galactans and a smaller number arabinans as neutral RGI side chains, with galactans dominating the soluble dietary fiber fraction. Application of an enzymatic xyloglucan profiling method demonstrated a substitution rate of 75% and established the presence of fucosylated xyloglucans. Both seed coat and embryo/endosperm polysaccharides were tested separately, revealing tissue-specific differences in the amounts of cellulose and RGI.
