自定内容

NTA of Greenyear is High temperature alpha-amylase, which is made from the best strain of Bacillus licheniformis through submerged fermentation and extraction technique. It can immediately hydrolyze starch, dextrin and soluble oligosaccharides in the α-1,4 glucosidase bond. FDA regards the strain as safety.
NTA of Greenyear possesses better heat resistance and adaptability under lower pH and calcium ion consistency. It is applied broadly for the liquidizing process in the industry of starch sugar, monosodium glutamate, alcohol, beer, organic acid, etc.

Application
Alcohol
Add NTA of Greenyear 0.15kg per ton of raw starch, adjust pH at 6.5-7.0, stir well with a pump or a continuous injection into the cooking pot liquid heaters, instantaneous temperature allowing up to 105℃, maintain tank temperature at 93-97℃, 60-100 minutes, send for saccharification after cooled.
Beer:
Materials mill through 40 mesh sieve, mixing in the paste pot, adjust pH, add NTA of Greenyear 0.15kg per ton of raw materials, maintain 95-97℃, liquefaction 30 minutes.
MSG, glucose, starch sugar:
According to process needs, adjust starch to a certain concentration of water, adjusting pH to 6.5-7.0, add 0.15-0.2% CaCl2 (by weight of raw materials), add Neozyme® HTAA 0.3kgs per ton of raw material.
In interval liquefaction, liquefied tank can be quickly heated to 95-97℃, 30-60 minutes liquid insulation.
In spray liquid, instantaneous temperature allowed to reach 105℃, maintain 95-97℃, 60-120 minutes liquid insulation.
Packaging

Storage
Should be stored in a dry place with temperature between 5-25℃.
Shelf life
6-9 months, subject to storage condition.
Safety
Enzyme preparations belong to protein, which may induce sensitization and cause allergic type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes or mucous membrane of nose, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
In textile desizing:The recommened optimum dosage are as follows:immersion method dosage:1-2g/L PH6.0-7.0,at
85-90degaree for 20-30 minutes .
