Protein Fortification Solutions for Food & Beverage

The Real Challenge of Smart Protein Formulation

Protein has become the universal language of nourishment, appealing to every demographic and 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.

When Formulation Gets Challenging

Proteins thicken too fast, they separate, turn chalky, dull a flavor or may even strip a familiar texture.

Protein formulation is rarely about a single ingredient, it’s about how each element interacts.

Why a Systems Approach Matters

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

Developed 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 SOLAE® range of plant proteins and fiber is anchored by SUPRO® Soy Protein Isolates, the most extensively studied soy protein in the industry, with a PDCAAS score of 1.00 comparable to egg and dairy.

For plant-based applications, we complement it with TRUPRO® Pea Protein and DANISCO® GRINDSTED® VEGPRO Carob Protein to help optimize protein quality.

Hydrocolloids, Stabilizers and Emulsifiers

DANISCO® range of hydrocolloids and texturants, including GRINDSTED®, AVICEL®, RECODAN® and VEGEDAN®, help control viscosity, prevent separation and create a smoother, more satisfying mouthfeel.

When it comes to high-protein beverages, they can make a big difference between a product consumers love and one they rather leave behind.

Antimicrobials, Fermentates and Fruit Inclusions

Plant proteins may contribute to 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. TAURA fruit pieces and paste deliver real-fruit indulgence with low sugar and high fiber content.

Protein That Performs Across Applications

Every protein application presents a different challenge. We design systems that perform at every stage—from pilot to production—and continue delivering throughout shelf-life.

Let’s Design Your Product

Tender, Resilient, Familiar

High-protein bakery products often lose softness, freshness or flavor as protein levels increase.

Stabilizers like DANISCO® AVICEL® MCC rebuilds crumb structure, retain moisture and protect freshness so a high-protein bread, biscuit or cookie still feels like the original.

Our INVENTIVE by IFF inclusions add the crunch, color and signature texture that turn a nutrition product into a much-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 perfecting texture, taste and stability around it.

Our portfolio includes SOLAE® SUPRO® Soy Protein Isolates, SOLAE® TRUPRO® Pea Protein and DANISCO® GRINDSTED® VEG PRO Carob Protein. Together with hydrocolloids, emulsifiers, fermentates, antioxidants and TAURA Fruit Pieces, they are delivered as integrated systems for a wide range of applications such as beverages, bars, bakery and dairy.

Yes. We support protein bar development across texture, bite and shelf-life targets, and high-protein bakery formulations optimized for crumb structure, moisture management and freshness. Our applications and R&D teams partner with manufacturers from concept through scale-up, accelerating development and supporting successful commercialization.

Absolutely. We create customized protein solutions tailored to your format, protein targets, label requirements and market needs. Our experts support every stage of development, from formulation and testing through scale-up and commercial launch.
