One.Prodcut presentation
Beta-dextranase(beta-1,3-1,4-glucosidase) is made by liquidfermentation deeply adopting Bacillus licheniformis bacterialstrain.This product is an endo protease,and it is usedspecially in Beta-dextranase’s 1,3 and 1,4 indican key,andgenerates 3-5 oligose and glucose.This product can dissovle validlyBeta glucose on the endosperm cytoderm of wheat and grain.It can beused to induce the viscocity of malt juice in the beerbrewing,improve the character of filter and the dissolution rate ofmalt,avoid beer mixture,stable the beer quality.
Two.Prduct specification and qualityindex
1, Operatingstandard:Q/FSMW001-2003.
2.Appearance:solid,tawny powder.
3. Enzymeactivity:1000,2000u/g.
4.Waterconcent: ≤8.0.
Three.Enzyem activity define
In thecondition of 40 centi grade,PH6.0,the quantity of using enzyme thathydrolyzing 1% barley Beta-dextranase can cause 1 micromole glucose can be defined as anenzyme activity unit.
Four.Using condition
Temperaturerange:30-60 centi grade,the most suitable temperature:50-55 centigrade;PH range:4.8-7.5,the most suitable PHrange:6.0-6.5.
Five.Using methods
You should addit when the malt start to sugar and the suitable quantity is100-300g per ton malt in the process of sugaring.
You can add itinto the fermentatin cylinder together with the cool malt juice,andthe suitable quantity is 4-10g per ton malt juice.
Six.Store condition
Product should be stored in dry and cool place.The enzyme activitywill not be below the signed enzyme activity and can last 12 monthsif it can be stored below 10 centi grade;enzyem activity can bemore than signed enzyme activity 95 percent and can last 6 monthsif this product can be store below 25 centi grade.
Seven.Attention
This prodcut adopt theinternational-popular marke unit of enzyme acitvity ofBeta-dextranase,which is 1000 times bigger than popular marked unitof enzyme activity in national feed business(In the case of 40centi grade,PH5.0,that every minute generates 1 micromole gulcosecan be seen as an enzyme activity).That is1000u/g of this productis the same with the 1000000 u/g of back,therefore,you should paysome attention to the define of the enzyme activity when you chooseBeta dextranase.
