About this supplement
Partially Hydrolyzed Guar Gum (PHGG) is a water-soluble, non-gelling dietary fiber derived from the guar bean (Cyamopsis tetragonoloba). It is produced through controlled enzymatic hydrolysis of guar gum, which breaks down the galactomannan polysaccharide into smaller, lower molecular weight fragments. This process improves solubility and reduces viscosity compared to native guar gum, making it easier to incorporate into foods and beverages without altering texture. PHGG is classified as a prebiotic fiber, meaning it selectively stimulates the growth and/or activity of beneficial bacteria in the colon. It is resistant to digestion in the upper gastrointestinal tract and is fermented in the large intestine, primarily by Bifidobacteria and Lactobacilli. It is odorless, tasteless, and has excellent stability across a wide pH and temperature range.

Physical properties
Fine, white to off-white powder. Highly soluble in cold and hot water, forming low-viscosity, clear solutions. Non-gelling. Stable across pH 2-10 and at high temperatures. Hygroscopic.
How it’s made
Produced from guar gum, which is extracted from the endosperm of guar beans (Cyamopsis tetragonoloba). The guar gum undergoes controlled enzymatic hydrolysis using specific enzymes (e.g., beta-mannanase) that cleave the galactomannan polymer backbone, reducing its molecular weight and viscosity. The process is followed by purification, filtration, and spray-drying to produce a consistent, soluble powder.
