Declared Enzyme: |
Acid Protease |
Systematic Name: |
EC 3.4.23.18 |
Activity: |
150,000 U/ml (minimum) |
Appearance: |
Brown Liquid |
Product pH: |
3.5 to 6.0 |
Specific gravity: |
1.15 to 1.25g/ml |
AP-530 works with pH ranges from 2.0 to 6.0 with its optimal pH from 2.5 to 3.5.
Effect of Temp
AP-530 can work effectively from 30 to 65°C with an optimal temperature range from 40 to 50°C.
In intermittent fermentation, it should be added at one time when the fermentation tank is filled with one third materials. In continuous fermentation, it should be added consecutively depending on the amount of saccharification mash fed at the inlet of fermentation tank.
Benefits
Use of AP-530 in fermentation process offers the following benefits:
1. Promote raw material particles dissolved
AP-530 can hydrolyze the proteins of the raw materials, thus destroy the interstitial cell wall structure of starch granules, so as to release the starch wrapped in the granules, which is conducive to saccharification.
2. Promote the growth of yeast with reproduction
Free amino nitrogen (FAN) is the most effective nitrogen source for yeast. Adding AP-530 during alcoholic fermentation can effectively hydrolyze proteins and peptides in the raw materials so as to generate FAN that yeasts can absorb, thus promote the growth of yeasts, increase the quantities of yeasts in the fermented mash, and shorten the fermentation cycle.
3. Beneficial to high concentration fermentation
In high concentration fermentation of alcohol, it is mainly nutritional deficiencies rather than the accumulation of alcohol that leads to the decrease of fermentation activity. Free amino acids (FAN) can not only shorten the fermentation cycle but also increase the output of alcohol, improve ethanol tolerance and survival rate of yeasts. Therefore, AP-530is the best nutrient for yeast growth and accelerator for fermentation.
