Description:
Acid Protease is obtained through submerged fermentation of Aspergillus niger. It is a proteolytic enzyme that, under acid conditions, breaks down polypeptides into short chain peptides and amino acids. It is widely used in the production of ethanol, white spirits (vodka, gin, tequila), leather processing, feed additives and single cell protein feed and food.
Technical information:
- Available in liquid (brown) and powder form (light brown)
- Temperature range: 30 to 65℃ (Optimum temperature: 55 to 65℃).
- pH range: 2.0-6.0 (Optimum pH: 2.5-3.5)
- Unit definition: One unit is the amount of enzyme needed to liberate 1 mg of tyrosine per minute of casein at pH 3.0; at 40 +/- 0.2 ℃
Mode of Action:
The aspartic protease present has a proteolytic effect that hydrolyzes polypeptides into smaller peptide molecules and amino acids.
Uses:
- Alcohol
In the manufacturing of fermented grain spirits such as whisky or rye helps to increase production of ethanol.
Recommended dosage: 0.05-0.15 L/ton of raw material based on 100,000 u/ml.
- Other Fermented products
In the manufacturing of vinegar, soy sauce, yellow rice, millet wine, white spirits.
Recommended dosage: 0.15-0.2L (kg)/ton of raw material based on 100,00 u/ml.
- Wool slenderizing
Acid Protease will have a shrink proof effect in the wool fiber and will improve its tenacity and extension.
Recommended dosage for a small lot: 0.6-2.0% (owf) at a pH 3.0-3.5 and a temperature of 40 to 50℃
Bath ratio: 1:20-40; keep it for 60 to 90 minutes.
Deweighting rate: 1-4%
- Feed
Acid Proteases reduce undigested protein in the GI tract, thus increasing energy values of the feed rations, and reducing protein fermentation in the large intestine resulting in better GI health.
Protease widens the range protein sources that can lower the cost of the ration without sacrificing performance.
Recommended dosage: 0.01-0.05 kg/ton of complete feed
- Single Cell Protein
Acid Proteases work very well in the manufacturing of SCP. Due to the nutritional value of its biomass (protein content 40%), SCP is used as supplements in human food and animal feed.
Recommended dosage: 0.01-0.02 kg/ton complete feed
SCP is a protein source for human food supplements and animal feeds.
Recommended dosage: 0.1 -0.2 L(kg)/ton of raw material.
