Instant Soy Protein Isolate for Food Processing
Yuxin Bio-Tech is a soy protein isolate manufacturer in China, supplying instant soy protein isolate for food manufacturers requiring rapid powder dispersion, convenient hydration, and consistent processing performance. Our instant and dispersible soy protein grades are designed to support efficient ingredient incorporation in suitable food formulations.

With a protein content of at least 90% on a dry basis, our instant soy protein isolate combines high protein concentration with application-oriented functional properties. We offer grade selection and customization to help customers meet specific mixing, solubility, viscosity, and processing requirements.

Key Functional Advantages
Fast Dispersion: Designed to disperse efficiently in suitable liquid systems, helping reduce powder clumping during ingredient incorporation.
Convenient Hydration: Supports easier incorporation of soy protein into formulations where mixing efficiency and hydration behavior are important.
Solubility Options: Different functional grades can be selected according to the required protein solubility and application conditions.
Viscosity Control: Low- and medium-viscosity requirements can be evaluated to match mixing, pumping, and processing needs.
High Protein Content: Provides at least 90% protein on a dry basis for high-protein food formulations.
Application Flexibility: Functional properties can be selected according to the intended food product and processing method.
Standard Product Specifications
Our instant soy protein isolate specifications include the following key physical and chemical requirements:

Protein (Dry Basis): ≥90.0%
Moisture: ≤7.0%
Ash (Dry Basis): ≤6.5%
Fat: ≤1.0%
Appearance: Light yellow or milky white powder
Microbiological Quality: Total bacterial count evaluated according to the GB 4789.2 sampling plan shown in the product specification.
These specifications provide a basis for initial supplier evaluation. Functional parameters such as dispersibility, solubility, viscosity, and particle size should be confirmed for the selected grade and intended application.

Standard, Optional & Custom Capabilities
Yuxin provides standard product specifications and supports optional or customized functional requirements based on the customer's formulation and processing conditions.

Standard: Protein ≥90%, moisture ≤7%, ash ≤6.5%, and fat ≤1%, as specified for the product.
Optional Moisture & Fat: Lower moisture targets, such as ≤5-6%, and lower fat targets, such as ≤0.5%, can be discussed for suitable grades.
Custom Particle Size: Powder fineness and sieve-passing requirements, including 100-mesh specifications, can be adjusted according to processing needs.
Custom Dispersibility: Target wetting and dispersion performance can be developed for specified mixing conditions.
Custom Solubility: NSI and related solubility requirements can be evaluated according to the intended formulation.
Custom Viscosity: Low- or medium-viscosity performance can be specified under agreed concentration, temperature, and testing conditions.
Custom Packaging: Packaging weight, materials, and labeling requirements can be discussed for bulk orders.
Custom targets are assessed according to technical feasibility and agreed testing conditions. For dispersion time, viscosity, or solubility requirements, please provide your target values and testing method so we can identify or develop a suitable grade.

Manufacturing & Product Development
Yuxin Bio-Tech specializes in soybean protein ingredients, with a product portfolio covering seven soy protein isolate series and more than 60 specialized varieties. Our range of functional protein products allows us to support different food processing requirements and application-specific product development.

As an industrial soy protein isolate supplier, we help customers compare available grades and discuss customized specifications rather than relying on one general-purpose product for every formulation.

Applications of Instant Soy Protein Isolate
Instant soy protein isolate is suitable for food processing applications where efficient powder dispersion and controlled hydration are important. Different grades may be selected for powdered beverages, liquid protein formulations, nutritional foods, and other compatible processing systems.

The appropriate grade depends on the formulation, protein concentration, mixing equipment, temperature, and desired finished-product characteristics.

Application & Grade Selection
Instant Protein Drinks: Fast-dispersing grades can help reduce clumping during beverage preparation. Cold-water dispersion, viscosity, and flavor compatibility should be evaluated.
Powdered Beverage Mixes: Suitable grades should provide good powder mixing and reconstitution performance. Particle size, wettability, and dispersion speed are important selection factors.
Plant-Based Protein Beverages: High-solubility and appropriate-viscosity grades can be considered according to beverage pH, protein concentration, and processing requirements.
Nutritional Food Formulations: Different grades can be evaluated for protein enrichment, ingredient compatibility, and mixing performance.
Food Processing Systems: Where rapid protein dispersion is required, the selected grade should be tested under the actual mixing conditions before production approval.
How to Choose the Right Instant Grade
When selecting instant soy protein isolate, consider the following technical requirements before comparing prices or requesting samples:

Cold or Hot Water: Confirm the temperature used during powder incorporation. Not every grade has the same cold-water or heat-processing performance.
Dispersion Speed: Specify the acceptable mixing time, water temperature, protein concentration, and agitation conditions.
Solubility: Check the required NSI or other solubility indicators under the intended formulation conditions.
Viscosity: Choose a suitable viscosity level based on the desired mouthfeel, mixing equipment, pumping, or filling process.
Particle Size: Confirm powder fineness and sieve requirements according to your preparation and mixing system.
Finished Product Stability: Evaluate sedimentation, texture, and appearance under actual processing and storage conditions where relevant.
Quality Requirements & Technical Documents
Our published instant soy protein isolate specification includes protein, moisture, ash, fat, appearance, and microbiological acceptance requirements. Buyers should confirm the current grade-specific technical documentation before approving a product for commercial production.

Technical Data Sheet: Verify physical, chemical, and relevant functional specifications.
Batch Quality: Confirm the availability of applicable batch analysis documents and acceptance criteria.
Microbiological Requirements: Review the applicable sampling plan, test method, and limits rather than relying on a single bacterial-count value.
Food Safety Compliance: Confirm the applicable requirements and current certification documents for the selected product and destination market.
Frequently Asked Questions
Can instant soy protein isolate disperse in cold water?
Cold-water dispersion depends on the selected grade and mixing conditions. Please provide your target water temperature, protein concentration, and mixing method so we can discuss a suitable grade and sample evaluation.

Does instant soy protein isolate dissolve completely without sedimentation?
Instant functionality primarily refers to improved wetting and dispersion. Complete dissolution and long-term stability depend on pH, protein concentration, temperature, other ingredients, and processing conditions. We recommend testing the selected grade in the actual formulation.

Can you provide low-viscosity instant soy protein isolate?
Low-viscosity requirements can be discussed as an optional or customized functional specification. Please provide the target viscosity, protein concentration, temperature, and measurement method for technical evaluation.

Can particle size and dispersion performance be customized?
Yes. Yuxin can discuss particle size distribution, sieve requirements, dispersion performance, solubility, and related functional properties. Final specifications are agreed according to the application and technical feasibility.

What information is needed to request a sample?
Please provide your intended application, protein specification, mixing conditions, target functional properties, and required sample quantity. If you are replacing an existing protein ingredient, its technical specification can help us compare suitable options.

How are MOQ, packaging, and delivery time confirmed?
These requirements are reviewed according to the selected grade, order quantity, packaging preferences, and destination. Please include your estimated purchasing volume and delivery requirements when requesting a quotation.
