1. Introduction
Through extensive screening across various bread applications, Natura Guide has optimized and launched ULTRA FRESH—a maltogenic amylase specifically tailored for China's industrial baking sector. It not only maintains bread softness and improves mouthfeel throughout the shelf life but also features high sugar tolerance and low dosage requirements.
Co-developed by Natura Guide and our Italian partner, this product adopts Europe's latest third-generation maltogenic amylase technology, making it more suitable for Chinese baking products. Natura Guide holds the exclusive sales rights in China.
2. Product Features & Advantages
- Maintains bread soft, moist and elastic throughout the shelf life
- Tolerates high-sugar formulas with low dosage while delivering equivalent freshness
- Perfectly preserves the product's freshness
Enzyme Activity vs pH & Temperature
- Optimum pH range: 5-7
- Optimum temperature range: 50-70°C
- No risk of excessive yeast activity
3. Test Application (Italian Partner Test Protocol)
Application: Sweet dough
We tested 3 different recipes:
- Recipe A: Standard, without maltogenic amylase
- Recipe B: With 50 ppm of competitor enzyme
- Recipe C: With 30 ppm of ULTRA FRESH
