Low-Viscosity Fiber Formulation
PHGG Formulation & Manufacturing
Develop PHGG-based nutrition products with a focus on fiber delivery, drinkability, texture, serving design and commercial manufacturability.
The Central Formulation Challenge
"How can a formulator add meaningful fiber without making the finished drink excessively thick?"
The answer depends on the interaction of multiple variables — not the fiber ingredient alone.
What Is Partially Hydrolyzed Guar Gum?
PHGG stands for Partially Hydrolyzed Guar Gum. It is produced by enzymatic hydrolysis of conventional guar gum — a process that breaks down the high-molecular-weight galactomannan polymer into shorter-chain fragments.
This structural change significantly alters formulation behavior. Conventional guar gum is known for producing high viscosity at relatively low concentrations — a characteristic that limits its use in drinkable nutrition products. Partial hydrolysis substantially reduces this viscosity-building tendency while retaining the soluble dietary fiber classification.
For nutrition powder formulators, PHGG is evaluated as a soluble fiber source that can be incorporated at meaningful levels without the texture and drinkability challenges associated with conventional guar gum. Final performance must be evaluated in the complete formula system.
PHGG vs Conventional Guar Gum
Conventional guar gum and PHGG are not interchangeable. Each requires independent formulation evaluation.
| Attribute | PHGG | Conventional Guar Gum |
|---|---|---|
| Processing | Enzymatically hydrolyzed to reduce molecular weight | Minimally processed; high molecular weight retained |
| Viscosity Behavior | Low to moderate viscosity at typical use levels | High viscosity even at low concentrations |
| Powder Formulation | More compatible with high-inclusion nutrition formulas | Viscosity limits practical inclusion levels in drinks |
| Drink Applications | Evaluated for protein shakes, fiber drinks, stick packs | Primarily used as a thickener/stabilizer at low levels |
| Serving Design | Allows higher fiber targets within drinkable formats | Serving size constrained by viscosity threshold |
Designing Fiber Without Excessive Viscosity
Fiber grams alone do not determine consumer experience. Final viscosity in a finished product is the result of multiple interacting variables — all of which must be evaluated together in the complete formula.

PHGG in Protein + Fiber Formulation
High protein combined with meaningful fiber creates a formulation engineering challenge — not just an ingredient selection decision.
Example Development Target
25g Protein × 10g Fiber
Protein Systems for Evaluation
PHGG can be evaluated in formulation development with a range of protein systems. Compatibility and performance must be assessed in the complete formula — not assumed from ingredient specifications alone.
PHGG for Daily Fiber Products
PHGG is evaluated for daily fiber powder applications where drinkability and serving size management are primary formulation objectives.
Formats
Example Development Targets
PHGG Stick Pack Formulation
Low-viscosity behavior alone is not sufficient for a successful stick pack product. The complete serving design must be evaluated.
Also evaluate:
PHGG in Fiber Hydration Formulas
PHGG may be evaluated in hydration-style fiber products. Compatibility with electrolytes, acidic flavor systems, and light beverage formats requires formulation testing — no commercial compatibility is claimed without verification.

PHGG and Acacia Fiber
Formulators may evaluate PHGG and acacia fiber in combination to achieve specific product requirements that a single fiber ingredient cannot fully satisfy.
This is a formulation concept, not a universal recommendation. The combination must be evaluated in the complete formula.
PHGG and Resistant Dextrin
PHGG and resistant dextrin represent two different soluble fiber systems that may be evaluated in combination for specific product development goals.
No validated commercial formula is claimed. Evaluation in the complete formula is required.

Flavor Development
Available for Formulation Development
PHGG cannot be evaluated independently from the complete flavor system. Flavor interaction with protein, sweetener, and other actives must be assessed in the complete formula.
Sweetener Systems
Sweetener selection interacts with fiber, protein, and flavor systems. No single sweetener system is universally superior — selection depends on the complete formula and target consumer profile.
