Special Protease ( Yeast Promoter JMCJ - 001 )
Introduction
Sunson Special Protease for Molasses or Corn Alcohol fermentation is produced by Aspergillus niger followed by separation, purification and then formulation with yeast promoter. This product hydrolyses protein under acid condition and promotes the growth of yeast.

Function
1. Promote yeast germination and growth, accelerate the fermentation, and shorten the fermentation cycle .
2. Increase ethanol yield and reduce the production cost.
3. Reduce the residual sugars and eutrophic substance precursor material to reduce the vinasse drying process Maillard reaction, reducing the pressure on sewage treatment.
Product uniqueness
1. It completely replaces nutrient salts such as urea and ammonium sulfate on molasses alcohol, and partially replaces urea and ammonium sulfate on corn alcohol. 2. Balance alcohol yeast nutrition (increasing cell number and germination rate ), adjust yeast osmotic pressure (osmotic pressure determines sugar consumption) , improve yeast high alcohol tolerance (lower sugar) and improve alcohol content . 3. The alcohol can be increased 0.6- 2.0% (v / v) when used in Molasses alcohol ; and the alcohol can be increased 0.3 ~ 0.6% (v / v ) when used in corn alcohol .
Dosage
The recommended dosage is 180-200 ml of the enzyme preparation per ton of total molasses materials and dosage is 100-180 ml of the enzyme preparation per ton of total corn materials, However, the optimal dosage depends on the application criteria, the processing parameters being utilized and the attributes desired in the hydrolysate being developed.
Recommended Storage
Best Before
| When stored as recommended, the product is best used within 12 months from date of delivery. |
Storage at customer’s warehouse | 5℃-15℃ |
Storage Conditions | This product should be stored in a cool and dry place in sealed container, avoiding insolation, high temperature and damp. The product has been formulated for optimal stability. Extended storage or adverse conditions such as higher temperature or higher humidity may lead to a higher dosage requirement. |

Safety and Handling Precautions
Enzyme preparations are proteins, which may induce sensitization and cause allergic type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
