Uses and synthesis of Soy protein isolate powder

Soy protein isolate powder is a kind of full-valent protein food additive produced by low temperature desolvation of soybean meal as raw material.Soy protein isolate CAS 9010-10-0 contains more than 90% of protein, nearly 20 kinds of amino acids, and contains essential amino acids.Soy protein isolate Raw Materials is rich in nutrition and does not contain cholesterol, it is one of the few varieties of vegetable protein that can replace animal protein. Soy protein isolate Raw Materials is rich in nutrients and free of cholesterol, it is one of the few plant proteins that can replace animal proteins.

Functions of Soy protein isolate powder

Soy protein isolate powder is a surfactant, it can reduce the surface tension of both water and oil, and water and air.

Applications of Soy protein isolate powder

‌1. Application in the food industry‌
‌Meat product improvement‌
As a water retainer and emulsifier, adding 2%~5% can improve the texture of products such as ham and sausage, prevent gravy separation, and replace 20%~40% of fish or meat ingredients.

It can enhance the protein content and enhance the flavor in high-end meat products.

‌Plant-based substitutes‌
It is used in vegetarian meat and plant-based dairy products (such as soy milk and vegetarian cheese) to simulate the texture and nutrition of animal protein.

‌Dairy products and baking‌
It can replace milk powder to make non-dairy beverages and ice cream, delay lactose crystallization, and improve emulsification.

It can enhance the protein content and taste of flour products such as bread and pastries.

‌2. Nutrition and health fields‌
‌Protein supplements‌
It has high bioavailability (absorption rate 90%~95%), suitable for protein powder and meal replacement products for lactose intolerant or vegetarian people.

Its low-calorie and high-protein characteristics assist weight management.

‌Special Food‌
Used in infant formula, sports food and medical nutrition formula.

‌3. Other innovative applications‌
‌Food preservation‌
As an edible coating agent (such as SPI-WPI composite film), it significantly reduces the decay rate and weight loss rate of citrus and other fruits, and prolongs the shelf life

Production methodprocess of Soy protein isolate powder

Soy protein isolate CAS 9010-10-0 is extracted from soybean meal (oil and water-soluble non-protein components are removed) in alkaline solution at low temperature, then precipitated, washed and dried to obtain protein powder with protein content more than 90%, Soy protein isolate Raw Materials structure and properties basically replace pure soy protein. Soy protein isolate Raw Materials basically replace pure soy protein in structure and properties.

‌1. Raw material processing‌
Use low-denatured defatted soybean meal (NSI value ≥80% can increase the extraction rate to more than 40%), which must meet the requirements of low fat and low impurities.

‌2. Alkali dissolution and acid precipitation method (mainstream process)‌
‌Alkali dissolution‌: Soybean meal is dissolved in an alkaline solution of pH 8-9 to separate fibers and carbohydrates.

‌Acid precipitation‌: Adjust the pH to 4.5 (isoelectric point of soybean protein) to precipitate the protein.

‌Water washing and drying‌: The precipitate is washed with water to remove impurities and then spray-dried to obtain a finished product with a protein content of ≥90%.

‌3. Other processes‌
‌Membrane separation method‌: Purify protein through ultrafiltration/microfiltration technology, avoid acid-base treatment, and retain higher activity.

‌Alcohol washing method‌: Use ethanol to precipitate protein, but it may affect functionality
