White Flakes
Low-Temperature Desolventizing System for High-Value Soy Protein Production
With the rapid growth of plant-based protein markets, the demand for high-quality soybean white flakes and low-temperature soybean meal is increasing worldwide. According to industry reports, the global plant protein market is expected to exceed USD 30 billion by 2030, driven by demand from food manufacturers, functional ingredients producers, and nutrition industries.
For processors producing soy protein concentrate (SPC), soy protein isolate (SPI), and textured soy protein (TSP), the quality of the raw soybean meal is critical. Conventional high-temperature desolventizing can lead to protein denaturation and reduced functional properties, limiting its value in high-end protein applications.
To address this challenge, low-temperature desolventizing technology has become the preferred solution for producing soybean white flakes with superior protein functionality.
With over 20 years of experience in oilseed processing technology, Myande Group provides reliable low-temperature desolventizing solutions designed to preserve protein quality while ensuring efficient solvent removal and stable plant operation.

FAQ
-
What are soybean white flakes used for in soy protein production?
-
Soybean white flakes are the primary raw material used in the production of soy protein concentrate (SPC) and other soy protein ingredients.
They are produced from dehulled and defatted soybeans through a low-temperature desolventizing process designed to preserve protein functionality. Unlike conventional soybean meal for feed, white flakes are specifically processed to maintain high protein solubility, which is essential for downstream protein extraction and concentration.
High-quality white flakes provide a stable starting material for SPC processing and help ensure consistent protein functionality in the final product.
-
-
Why is low-temperature desolventizing critical for producing soybean white flakes?
-
Low-temperature desolventizing is essential because excessive heat can cause protein denaturation, which reduces the functional value of soy protein.
In SPC production, maintaining high protein solubility is critical for efficient removal of soluble carbohydrates and other non-protein components during extraction. If the meal is overheated during desolventizing, protein functionality may be permanently damaged.
Therefore, white flake production focuses on gentle solvent removal under controlled temperature and vacuum conditions, ensuring that protein properties are preserved for downstream food-grade processing.
-
-
How do soybean white flakes influence SPC yield and production efficiency?
-
The quality of soybean white flakes has a direct impact on SPC yield, extraction stability, and product consistency.
White flakes with high protein solubility and uniform structure allow efficient removal of soluble components while maintaining the integrity of the protein matrix. This results in more stable extraction behavior and improved overall SPC production efficiency.
Poor-quality flakes, on the other hand, may cause unstable extraction conditions, reduced protein recovery, and inconsistent product quality.
-
-
What quality parameters are important for soybean white flakes used in SPC production?
-
Several key parameters are typically evaluated when selecting white flakes for SPC production, including:
- Protein solubility (PDI / NSI)
- Residual oil content
- Residual solvent level
- Moisture content
- Particle integrity and color
These factors determine how well the flakes perform in downstream protein processing and whether the final SPC product can meet food-grade quality requirements.
-
-
How does white flake quality affect the functionality of soy protein products?
-
Protein functionality—such as solubility, emulsification, and water-binding capacity—is strongly influenced by the thermal history of the soybean material.
White flakes produced under controlled low-temperature conditions help preserve these functional properties. This is particularly important for food applications where protein performance directly affects product texture, stability, and nutritional value.
Maintaining protein functionality is therefore one of the primary goals of white flake processing.
-
-
Can a soybean white flakes production line be integrated with SPC or SPI plants?
-
Yes. In many modern soy protein projects, white flake production is integrated directly with downstream SPC or SPI processing lines.
This integrated approach allows better control of raw material quality, reduces transportation and storage risks, and improves overall production efficiency.
Turnkey engineering solutions often design white flake processing as the upstream foundation of the entire soy protein production system.
-
-
How do I evaluate a supplier for a soybean white flakes production line?
-
Key evaluation factors include:
- Experience in soy protein processing technology
- Capability in low-temperature desolventizing design
- Integration with SPC/SPI production lines
- Automation and process stability
- Proven project references
A supplier with strong expertise in both oilseed processing and plant protein production can provide a more reliable solution for white flake production.
