Specialized water treatment system for plant-based protein production - Ensuring consistent color and quality of products
1. How does water quality affect plant-based protein products?
Chain reaction of color and odor
🌱 Natural color issues:
• Humic acid/tannic acid in water causes product to be gray/yellowish
• Customer complaints ↑ 15% per 0.1ppm increase in color
👃 Flavor interference:
• Sulfides/earth odorants cause soybean odor residue
Industry Data: Global Plant Protein Market will reach $16.2 billion by 2025 (MarketsandMarkets) Water quality complaints account for 32% of quality issues.
2. Customized water treatment process
Three steps to remove pigments and impurities
① Deep pre-treatment
• Activated carbon adsorption: remove 98% humic acid (color <5PCU)
• Oxidation tower: ozone destroys the chromogenic groups
② Core purification
anti-pollution RO membrane:
• Retention of pigment molecules with molecular weight >100Da
• Desalination rate > 99% (conductivity ≤ 10μS/cm)
③ Terminal protection
• UV sterilization: 254nm ultraviolet ray kills microorganisms
• Titanium rod filtration: 0.2μm absolute filtration precision
Process Comparison:
| Indicator | Conventional Process | This System |
|---|---|---|
| Colorimetry Removal Rate | 60% | 99% |
| Protein Yield | 92% | 97% |
| Odor Complaint Rate | 8% | <0.5% |
3. Successful cases: pea protein production line
Reform project of a leading enterprise in Shandong
Original problem:
• Color difference ΔE>3 between product batches (visible to the naked eye)
• Monthly rework losses due to water quality ¥ 18 million
Solution:
• Installation of 20T / H dedicated RO system
• Add online color monitor
Results:
✅ Color difference ΔE stabilized <1.5
✅ Protein extraction rate increased by 5%
✅ Passed Beyond Meat supplier audit
