Description

Soy protein isolate is a functional ingredient obtained by water extraction and purification, containing a minimum of 90% protein in dry matter. The product is a light-coloured powder with a creamy shade, neutral taste and very good solubility.

Soy protein powder is characterised by low fat content, low moisture and a wide pH range. It is GMO-free and meets the microbiological requirements for the food industry, making it an excellent ingredient in high-protein, plant-based and functional recipes.

Technical aspects

Soy protein concentrate is characterised by a fine particle structure, high nutritional value and a stable physicochemical profile. Soy protein isolate has a natural appearance, uniformity and is convenient for use in industrial production.

Parameter	Value
Protein content (dry matter)	min. 90%
Moisture content	max. 7%
Fat content	max. 1%
Ash content	max. 6%
pH	6.8–7.8
Particle size (100 mesh sieve)	98–99%

Application

Soy protein isolate is used in the production of high-protein foods such as plant-based drinks, supplements, snacks, baked goods and meat substitutes. Its high functionality supports the texture and stability of the final product.

Soy protein isolate is also suitable for dietary, sports and vegan products. Soy protein powder can be used in clean label recipes – without flavourings or unnecessary fillers.

Storage

Soy protein powder should be stored in a cool, dry place in its original packaging. Once opened, it is recommended to protect the product from air and moisture.

Package

Isolated soy protein is packed in paper-plastic bags with a polyethylene insert, weighing 20 kg. The packaging complies with food safety standards.

Frequently Asked Questions

How does soy protein isolate differ from other plant proteins?

Soy protein isolate contains a high percentage of protein with minimal carbohydrates and fat. Compared to pea or rice protein, soy typically has a more complete amino acid profile, containing all essential amino acids.

How does soy protein isolate compare nutritionally to whey protein?

Soy protein isolate is typically slightly less digestible than whey, but it still provides all the essential amino acids. It can be a good plant-based alternative for protein needs, although individual results may vary depending on diet and goals.

What are the main functional properties of soy protein isolate?

Soy protein isolate has good emulsifying, water-binding, and gelling properties. It affects the texture, stability, and structure of food products.

What are the differences between soy protein isolate and concentrate?

Isolate contains a higher proportion of protein and less carbohydrates and fat than concentrate. It is a more purified form, used where a high concentration of protein is required.

In which industries and products is soy protein isolate used?

Soy protein isolate is used, among others, in plant-based products, meat substitutes, beverages and protein supplements, baked goods, and functional foods.

Where can you buy soy protein isolate?

Soy protein isolate can be purchased through the FDCM platform, which offers raw materials and ingredients used in food, supplements, and feed.
