Product Introduction
Soy Protein Concentrate (SPC) is a versatile plant protein ingredient made from non-GMO soybeans. Its protein content is 70 ± 5%. It also keeps the natural dietary fiber of the soybean, so it combines high protein with rich fiber.
SPC is valued in food manufacturing for its emulsifying, water-absorbing, gelling and water- and oil-retaining properties. It improves texture and mouthfeel, and it raises the protein content and nutritional value of the finished product.
As a professional China soy protein concentrate manufacturer, supplier and exporter, WEHENGFOOD™ supplies consistent, food-grade SPC to meat processors, bakeries and plant-based food brands worldwide.
Key Features & Advantages
- High protein, high fiber: 70 ± 5% protein plus abundant dietary fiber
- Non-GMO: made from non-genetically-modified soybeans
- Excellent emulsification: stabilizes fat and water in emulsified meat systems
- Strong water absorption: improves yield and juiciness
- Good gel strength: builds firm, elastic texture in sausages, ham and tofu products
- Water and oil retention: reduces cooking loss and keeps products moist during processing and freezing
- Nutritional boost: raises protein content without changing product structure

Functions of Soy Protein Concentrate in Food
| Function | What It Does in Your Product |
|---|---|
| Emulsification | Binds fat and water to prevent oil-off and give a smooth, uniform texture |
| Water absorption | Holds moisture to improve yield, tenderness and juiciness |
| Gelation | Forms a stable gel network when heated, improving bite and sliceability |
| Water & oil retention | Reduces purge and cooking loss, and keeps texture stable through freezing and thawing |
| Texture improvement | Enhances mouthfeel and structure in meat, vegetarian and bakery foods |
| Protein fortification | Increases protein content and nutritional value of the finished food |
Applications
- Emulsified sausages and hot dogs: improves emulsion stability, firmness and yield
- Ham and cooked meat products: better water retention, slicing and juiciness
- High-temperature (retort) sausages: keeps structure stable after sterilization
- Dried tofu sheets (qianye tofu) and vegetarian products: builds chewy, meat-like texture
- Baked goods: adds protein and improves moisture retention and softness
- Vegetable foods and frozen foods: protects texture through freezing and reheating

FAQ
Q1: What is soy protein concentrate (SPC)?
Soy protein concentrate is a food-grade protein ingredient made from non-GMO soybeans. It contains about 70% protein and retains soybean dietary fiber. It is widely used in meat products, bakery foods and plant-based foods.
Q2: What is the protein content of your soy protein concentrate?
Our SPC has a protein content of 70 ± 5%.
Q3: What is soy protein concentrate used for?
It is mainly used in emulsified sausages, hams, high-temperature sausages, vegetarian products, dried tofu sheets, baked foods, vegetable foods and frozen foods. It improves texture, water retention and nutritional value.
Q4: Is your soy protein concentrate non-GMO?
Yes. It is made from non-GMO soybeans.
Q5: What is the difference between soy protein concentrate and soy protein isolate?
SPC contains about 70% protein and keeps dietary fiber, so it is a cost-effective choice for functional use in meat and vegetarian products. Soy protein isolate is more refined, with about 90% protein and very little fiber. Choose SPC when you want strong water absorption, emulsification and gelation at a lower cost.
