Konjac glucomannan (Viscosity≥15000mPa.s)
Based on 1 Customer Validation
Konjac glucomannan (Viscosity≥15000mPa.s) is an orally active acetylated (1-4)-β-D-glucomannan with multiple biological activities including anti-diabetic, anti-obesity, anti-inflammatory effects, as well as film-forming and gelling properties. Konjac glucomannan (Viscosity≥15000mPa.s) forms a defensive coating on the intestinal surface, reducing levels of blood glucose, cholesterol, triglycerides and blood pressure; it is specifically degraded by colonic β-mannanase produced by human colonic bacteria. Konjac glucomannan (Viscosity≥15000mPa.s) can be used as a food additive, dietary supplement and excipient for oral colon-targeted drug delivery systems. Konjac glucomannan (Viscosity≥15000mPa.s) is applicable to research related to various diseases such as type 2 diabetes, obesity, atopic dermatitis and metabolic syndrome, as well as research in fields including biotechnology, pharmaceuticals and tissue engineering.

Biological Activity
Konjac glucomannan (Viscosity≥15000mPa.s) hydrolysate exerts prebiotic effects by promoting the growth of beneficial Lactobacilli and Bifidobacteria strains in vitro[1].
Konjac glucomannan (Viscosity≥15000mPa.s) hydrolysate exhibits stronger structural stability at pH = 11 and 368 K due to increased hydrogen bond formation; in contrast, urea reduces its structural stability by decreasing hydrogen bonds[3].

Konjac glucomannan (Viscosity≥15000 mPa·s) (2.5-5% liquid konjac powder; p.o.; daily; 80 days) prevents obesity in male C57BL/6J mice by reducing abdominal and hepatic lipid accumulation and regulating obesity-related serum indicators[1].
Konjac glucomannan (Viscosity≥15000 mPa·s) (administered orally; daily dosing; for 45 consecutive days) significantly improves anti-obesity activity in obese male Sprague-Dawley rats[1].
Konjac glucomannan (Viscosity≥15000 mPa·s) (p.o.; daily; 8 or 9 weeks) induces anti-inflammatory immune responses in atopic dermatitis NC/Nga mice[1].
Konjac glucomannan (Viscosity≥15000 mPa·s) coats porous hydroxyapatite scaffolds, and the modified scaffolds achieve efficient bone repair in Rattus norvegicus by matching the scaffold degradation rate to new bone growth, as well as promoting osteogenic differentiation and angiogenesis[3].
Konjac glucomannan hydrolysate (Viscosity≥15000 mPa·s) (administered orally; daily dosing; for 4 consecutive weeks) inhibits IgE production in ovalbumin-immunized Balb/c mice, making it a practical dietary supplement for the prevention of atopic diseases[1].
Konjac glucomannan (Viscosity≥15000 mPa·s) (administered orally; daily; starting 2 weeks before colitis induction and continuing throughout the study period) alleviates Oxazolone (HY-126360)-induced colitis in C57BL/6 mice by promoting Th1-polarized immune responses[1].
