Protein Fortification Solutions for Food & Beverage

The Real Challenge of Modern Protein Formulation

Protein has become the universal language of nourishment — appealing to every demographic, across every meal occasion. Our elevated nutrition approach starts from a simple truth: adding protein is the easy part. Making it delicious, smooth and stable is where formulation gets hard.

Where Formulation Breaks Down

Proteins thicken too fast. They separate. They turn chalky, dull a flavor or strip a familiar texture. Protein formulation is rarely about a single ingredient — it’s about how every element interacts.

Why a Systems Approach Matters

Protein formulation development demands proteins paired with the right hydrocolloids, emulsifiers, taste modulation and shelf-life protection — engineered together from day one. That’s how brands move from “high in protein” to “high in repeat purchase.”

Engineered as a System

Protein Fortification Food Ingredients

At IFF, we don’t simply add protein — we elevate it. Our protein fortification food ingredients pair high-performing plant proteins with hydrocolloids that perfect viscosity, emulsifiers that maintain stability, and antioxidants and fermentates that preserve freshness.

High-Quality Plant Proteins

Our soy protein and fiber portfolio is anchored by SUPRO® soy protein isolates — the most extensively studied soy protein in the industry, with a 1.00 PDCAAS score comparable to egg and dairy.

We pair it with TRUPRO® pea protein and GRINDSTED® VEG PRO carob protein for plant-based briefs.

Hydrocolloids, Stabilizers and Emulsifiers

Our hydrocolloids and texturants — GRINDSTED®, AVICEL®, RECODAN® and VEGEDAN — control viscosity, prevent separation and rebuild mouthfeel.

Paired with our emulsifiers, they’re the difference between a high-protein beverage that drinks like silk and one that drinks like a chore.

Off-Note Management and Shelf-Life Protection

Plant proteins bring bitterness and earthy notes. Our antioxidants and plant extracts protect flavor and color through processing and shelf life.

Our antimicrobials and fermentates keep proteins fresh with cleaner labels. And our fruit pieces and paste (TAURA) deliver real-fruit indulgence with low sugar and high fiber.

Protein That Performs Across Real Applications

Every category has its own protein puzzle. We tune the system to the format — designed to perform from pilot through scale-up, and to hold up across shelf life

Let’s Design Your Product

Tender, Resilient, Familiar

High protein bakery products often lose tenderness, freshness or flavor as protein loads climb.

Stabilizers like AVICEL® microcrystalline cellulose rebuild crumb structure, retain moisture and protect freshness — so a high-protein bread, biscuit or cookie still feels like the original.

Our inventive inclusions add the crunch, color and signature texture that turn a nutrition product into a craved one.

Frequently Asked Questions

About Protein Fortification

Protein fortification is the practice of adding high-quality protein to food and beverages to deliver greater nutritional value — typically supporting claims like “high in protein” or “good source of protein.” At IFF, we treat it as a systems challenge: proteins, hydrocolloids, taste modulation and shelf-life protection working together.

Proteins interact with everything — water, fat, sugar, fiber, heat, time. Add too much and viscosity climbs, taste turns chalky, and shelf life shortens. Successful protein formulation development means choosing the right protein for the format, then engineering texture, taste and stability around it.

Our portfolio includes SUPRO® soy protein isolates, TRUPRO® pea protein and GRINDSTED® VEG PRO carob protein, paired with hydrocolloids, emulsifiers, fermentates, antioxidants and TAURA fruit pieces — delivered as integrated systems for beverages, bars, bakery and dairy.

Yes. We support protein bar formulation across hardness, bite and shelf-life targets, and high protein bakery products across crumb, moisture and freshness. Our applications labs partner with R&D teams from concept through scale-up.

Absolutely. We build custom protein solutions tailored to your format, protein target, label requirements and market. We iterate fast, test against sensory and stability targets, and support pilot-to-commercial transition.
