Soy Protein Isolate, Isolated Soy Protein, Soya Protein, 9010-10-0

🌱 Soy Protein & Soy Protein Isolate

What is Soy Protein?

• Soy protein is derived from the soybean (Glycine max), a plant naturally rich in protein.

• It is widely used in the food industry as an alternative to animal protein, either on its own or combined with meat.

• Soy protein is considered a high-quality plant-based protein because it contains all essential amino acids.

Main Types:

1. Soy Protein Isolate (SPI)

   • Highly purified form of soy protein.

   • Contains ~90% protein with minimal fat and carbohydrates.

   • Popular in vegan/vegetarian diets and sports nutrition.

2. Soy Protein Concentrate (SPC)

   • Less refined than isolate.

   • Higher fat and carbohydrate content.

   • Commonly used in processed foods like sausages, bakery products, and meat substitutes.

What is Soy Protein Isolate?

• A highly refined protein powder obtained from soybeans.

• Produced by removing most fats and carbohydrates, leaving a product that is almost pure protein.

• CAS Number: 9010-10-0

• EINECS: 232-720-8

• Synonyms: Isolated Soy Protein, Soya Protein, Soy Protein Isolated

Chemical Composition:

• ~90% protein

• Low in fat and cholesterol-free

Extraction Process:

• Soybeans are soaked in acid or alcohol to remove sugars and fiber.

• The remaining protein is dehydrated into a fine powder.

Benefits

• Complete protein: Contains all 9 essential amino acids.

• Heart health: Helps lower cholesterol and supports cardiovascular function.

• Nutrient-rich: Provides B vitamins, zinc, and iron.

• Weight management: Increases satiety and supports muscle development.

• Isoflavones: Plant compounds that may help regulate hormone balance.

Considerations

• Residues: The extraction process may leave traces of chemicals or metals.

• Allergies: Not suitable for individuals with soy protein allergy.

• Thyroid health: People with thyroid conditions should consult a doctor before consuming.

Common Uses

• Protein supplements & shakes

• Infant formula

• Meat alternatives (burgers, sausages, patties)

• Dairy alternatives

• Bakery products & protein bars

Frequently Asked Questions

• Can soy protein be consumed with soy allergy? → No, avoid soy products.

• Is soy protein harmful for thyroid problems? → Consult a doctor before use.

• Can soy protein help with weight loss? → Yes, by promoting fullness and reducing calorie intake.

• How much should be consumed daily? → Around 50 g, depending on individual protein needs.

Soy Protein Isolate – Sectoral Suitability, Production, and Usage Ratios

1. Production Process (Summary)

• Raw material: Soybeans (Glycine max)

• Steps:

  • Removal of fats and carbohydrates (acid/alcohol extraction)

  • Separation of protein fraction

  • Drying and conversion into powder

• Final product: Powder with ~90% protein, low fat, cholesterol-free

2. Sectoral Suitability Table

3. Usage Ratios (General Industry Practices)

• Protein Supplements: 70–100% (main protein source)

• Meat Alternatives (burgers, sausages, patties): 10–30% (texture and binding properties)

• Infant Formula: 5–15% (balanced with other proteins)

• Bakery Products: 3–8% (protein enrichment)

• Functional Foods (bars, beverages): 10–25%

4. Sectoral Evaluation

• Advantages: Complete amino acid profile, low fat, cholesterol-free, vegan-friendly.

• Risks: Allergy potential, extraction residues, thyroid sensitivity.

• Regulation: EFSA, FDA, and Turkish Food Codex set limits for infant formula and functional foods.
