1. Description:
1). Process function
Glucoamylase breaks down α -1, 4 glucosidic bound of starch from non-reducing end into glucose, as well as breaking α -1, 6 glucosidic bound slowly.
2). Thermal stability
St able under the temperature of 60. Optimum temperature is 5860.
3). Optimum pH is 4. 0~4.5.
Appearance Brown liquid
Enzyme activity 100,000μ/ml to 150,000μ/ml
Capability(g/ml) 1.05---1.1
Enzyme livability: In three months, the enzyme livability is no less than the 90% of enzyme livability.
2. Definition of enzyme activity unit:
1 unit activity equals to the amount of enzyme get from 1ml liquid glucoamylase to hydrolyze soluble starch to get 1 mg glucose in 1 hour at 40, pH=4. 6.
3. Recommendation in application
1). Alcohol Industry: Steam and Boil the raw material with medium temperature, then cool down to 58-60.Add glucoamylase, recommended dosage is 80--200μ/g raw material. Keep the temperature for 30-60 mins, then cool down to 30 to ferment.
2). Starch Industry: Liquify the raw material, adjust the PH value to 4.2-4.5, cool down to 5860, Add glucoamylase, recom mended dosage is 100-300μ/g raw material. Keep the temperature for 24-48 hrs.
3). Beer Industry: when producing dry beer, add glucoamylase before fermenting, which could strengthen the fermentation ability.
4). Brewage Industry: when producing wine, yellow wine, using glucoamylase instead of wine yeast could make the more final product. It is widely used in vinegar industry.
5). Other: when applying in MSG and antibiotics industry, liquefy the starch and cool down to 60, adjust PH value to 4.2-4.5, add glucoamylase, recommended dosage is 100-300μ/g raw material.
4. Packing
It is packed in toxin free plastic drum. 1100KG/drum or 25KG/drum. We can also pack according to clients requirement.
Liquid Glucoamylase enzyme activity from 120000-150000u/ml
