High-protein products have become a standard expectation across many food categories, from beverages and dairy alternatives to bakery, snacks, and processed foods. However, meeting these expectations is not just about adding protein. To ensure product success, food manufacturers must also deliver the right texture, stability, and sensory profile, often while managing cost and production efficiency.
This is where isolated soy protein (ISP) plays an essential role—not just as a protein source, but also as a functional ingredient that helps address formulation challenges.
What Is Isolated Soy Protein?
Isolated soy protein is a highly refined form of soy protein containing ≥90% protein on a dry basis. It is produced by removing most fats and carbohydrates from defatted soy flour, resulting in a highly functional protein ingredient with a relatively neutral flavour profile.
ISP solves technical challenges through several key functional properties:
Where ISP Makes the Difference
Advantages of ISP in Food Manufacturing
In a market with a growing range of protein ingredients, ISP continues to be widely used due to its balanced performance across nutrition, cost, and formulation.
1. High Protein Quality (PDCAAS 1.0)
Comparable to animal-based proteins in terms of digestibility and amino acid availability.
2. Cost Efficiency at Scale
Offers a more stable and cost-effective solution compared to many protein sources, especially in high-volume manufacturing.
3. Neutral Flavour Profile
Allows easier integration into different formulations while reducing the need for flavour masking, helping simplify formulation and control costs.
4. Label Simplification
Serves as a multi-tasking ingredient, helping to reduce the need for additional ingredients and support clean label formulations.
Achieving the ideal balance of texture, taste, and cost is critical for product success.
