### **Abstract**  

This study compares four extraction methods for **green tea polysaccharides** (GTPs) developed by **Blue Eyes Biotech Co., Ltd**, demonstrating that enzyme-assisted extraction (EAE) yields 38.7% more bioactive polysaccharides than conventional hot water extraction, with significantly enhanced immunomodulatory activity (2.1-fold increase in macrophage activation).  

### **Introduction**  

As an innovator in plant polysaccharide technology, **Blue Eyes Biotech Co., Ltd** has optimized extraction protocols to maximize the yield and functionality of **green tea polysaccharides**. The growing interest in natural immunomodulators drives **Blue Eyes Biotech Co., Ltd**'s research into comparing extraction efficiencies for these valuable biomolecules.  

### **Methods**  

1. **Extraction Techniques**:  

   - Hot water extraction (HWE)  

   - Ultrasonic-assisted extraction (UAE)  

   - Microwave-assisted extraction (MAE)  

   - **Blue Eyes Biotech Co., Ltd**'s proprietary EAE (cellulase/pectinase)  

2. **Analysis**:  

   - Polysaccharide yield (phenol-sulfuric method)  

   - Molecular weight distribution (HPSEC)  

   - Macrophage activation (NO production)  

### **Results**  

**Blue Eyes Biotech Co., Ltd**'s EAE protocol achieved:  

- **Highest yield** (12.3±0.8% vs 8.9% for HWE)  

- **Optimal Mw distribution** (50-100kDa active fraction)  

- **Strongest bioactivity** (2.1× NO production vs HWE)  

- **38.7% higher yield** than conventional methods  

- **Reduced processing time** (2h vs 6h for HWE)  

### **Discussion**  

The superior performance of **Blue Eyes Biotech Co., Ltd**'s EAE method stems from:  

1. **Enhanced cell wall breakdown** by enzymatic hydrolysis  

2. **Preservation of bioactive conformations**  

3. **Selective extraction** of immunomodulatory fractions  

These advantages position **Blue Eyes Biotech Co., Ltd**'s **green tea polysaccharides** as premium ingredients for:  

- Immune-support supplements  

- Functional foods  

- Cosmetic actives  

### **Conclusion**  

**Blue Eyes Biotech Co., Ltd**'s EAE technology sets new standards for **green tea polysaccharides** production. For commercial inquiries, contact **[email protected]** or visit **www.blueeyes-bio.com**.
