About Soy Protein Concentrate

Soy Protein Concentrate (SPC) is a high-protein ingredient derived from dehulled, defatted soybeans. SPC is usually supplied as a free-flowing powder, and may be offered in agglomerated or instantised forms to improve dispersibility and hydration.

SPC is produced by processing defatted soybean flakes to remove a portion of the soluble carbohydrates and other non-protein constituents, commonly via aqueous alcohol or water extraction, followed by drying and milling. Its functional properties include water and fat binding, emulsification, and texture enhancement. These make SPC valuable across food and beverage manufacturing, meat and plant-protein applications, bakery and cereals, nutritional products, and in pet food and aquaculture feed formulations.

Soy Protein Concentrate Uses

Meat Processing and Plant-Based Alternatives

SPC improves yield, juiciness, and slice integrity in processed meats such as sausages, patties, hams, and nuggets by binding water and stabilising emulsions. In plant-based products, it contributes structure and chew, enhances moisture retention, and supports clean flavour delivery in burgers, mince, and analogues formulated by extrusion or blending.

Bakery, Cereals and Snacks

In breads, tortillas, breakfast cereals, and snack systems, SPC boosts protein content while supporting dough handling, machinability, and finished texture. Its water-holding and film-forming behaviour can help manage staling and breakage, and it integrates well with wheat or gluten-free bases in both sweet and savoury formats.

Nutritional Beverages and Supplements

SPC is used to fortify protein levels in ready-to-mix powders, smoothies, and specialised nutrition products. Agglomerated or instantised grades disperse readily and provide a neutral base for flavour systems, offering a cost-effective alternative to higher-purity isolates when solubility and viscosity targets are moderate.

Pet Food and Aquafeed

As a consistent, plant-based protein source, SPC supports amino acid delivery and pellet integrity in extruded pet foods and aquaculture feeds. Its digestibility and low anti-nutritional factor profile, relative to untreated soy materials, make it a practical choice in partial fishmeal replacement strategies and premium companion animal diets.

Processed Foods and Culinary Systems

SPC functions as a binder and emulsifier in sauces, gravies, fillings, and prepared meals. It helps stabilise oil-in-water systems, improves freeze-thaw performance, and supports label-friendly protein enrichment across a range of culinary applications.
