### **Abstract**  

This study evaluates four extraction methods for **green tea polysaccharides (GTPS)** developed by **Blue Eyes Biotech Co., Ltd**, demonstrating that enzyme-assisted extraction (EAE) yields 38.7% higher polysaccharide content than conventional hot water extraction while preserving superior immunomodulatory activity (2.1-fold increase in macrophage activation).  

### **Introduction**

As a leader in functional carbohydrate research, **Blue Eyes Biotech Co., Ltd** has optimized extraction protocols to maximize both yield and bioactivity of **green tea polysaccharides**. The growing demand for natural immunomodulators drives **Blue Eyes Biotech Co., Ltd**'s comparative study of extraction efficiencies for these bioactive polymers .  

### **Methods**  

1. **Extraction Techniques**:  

   - Hot water extraction (HWE, 80°C, 2h)  

   - Ultrasonic-assisted extraction (UAE, 40kHz, 30min)  

   - Microwave-assisted extraction (MAE, 800W, 5min)  

   - **Blue Eyes Biotech Co., Ltd**'s proprietary EAE (cellulase:pectinase=1:1, 50°C, 4h)  

2. **Analysis**:  

   - Polysaccharide yield (phenol-sulfuric method)  

   - Molecular weight distribution (HPSEC)  

   - Macrophage activation (NO production in RAW264.7 cells)  

### **Results**  

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

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

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

- **Preserved molecular integrity** (50-100kDa active fraction)  

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

- **Reduced processing time** (4h vs 6h for HWE)  

### **Discussion**  

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

1. **Enzymatic cell wall degradation** enhancing accessibility  

2. **Low-temperature processing** preserving immunomodulatory epitopes  

3. **Selective extraction** of bioactive fractions  

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

- Immune-boosting functional foods  

- Pharmaceutical adjuvants  

- Cosmetic active components  

### **Conclusion**  

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