🧬 What is PHGG (Partially Hydrolyzed Guar Gum)?

PHGG is a water-soluble dietary fiber derived from guar gum, which is extracted from the endosperm of guar beans (Cyamopsis tetragonoloba). Through enzymatic hydrolysis, the long-chain galactomannans in guar gum are broken down into lower molecular weight polysaccharides — making PHGG easier to dissolve, better tolerated, and functionally more versatile.

Unlike raw guar gum, PHGG:

• Is non-gelling, fully soluble, and forms a clear solution

• Has low viscosity, even at high concentrations

• Is clinically recognized as a prebiotic fiber with low-FODMAP properties

Structure: Galactomannan backbone (galactose:mannose ratio ~1:2)
Form: Light beige to white powder
Solubility: Fully water-soluble (clear, neutral taste)
