Make Inquiry
Beta glucan enzyme GY-101/GY-202
● Brief introduction
Beta glucan enzyme is a kind of high efficient biological preparation by superior strain by extraction liquid deep fermentation and advanced after preparation, and containing hemicellulase certain, widely used in beer production.
● Mechanism of action
In the saccharification of high temperature, especially to the rise in the saccharification temperature 60 ℃, mashing ingredient of barley malt will be a lot of beta glucan released into the wort, and the endogenous β - malted barley glucan synthase has been insufficient endogenous enzyme inactivation, often causing filter difficult and wort turbidity. Add the endo beta glucanase, acting on the beta glucan -1,4 glycosidic bond, the decomposition of the major product for 1-5 polymerization degree of oligosaccharides
● Effect
Reduce wort viscosity, increases the rate of filtration and clarification of wort;
Improve wine filtering efficiency, reduce the loss of the filter liquor;
Improve beer colloid stability, eliminate the beta glucan induced cold haze;
Degradation of beta glucan, improve efficiency in the use of membrane process in the production of pure draft beer, prolonging the service life of the membrane.
● Enzyme activity
Beta glucan enzyme GY -101
8000 IU/g
Beta glucan enzyme GY -202
20000 IU/g
The definition of unit activity (IU): at 50 ℃, pH4.8 condition, 1 minutes hydrolysis of barley beta glucan produced 1 μ mol reducing sugar (glucose meter) the amount of enzyme required for the 1 enzyme activity unit.
● Better thermal stability, effective temperature range:30-65 ℃, optimum temperature range :45 - 55 ℃.
Method of use
The beer saccharification recommended dosage is 100-300g/ tons of malt dry weight, the optimal dosage is determined according to the customer the experiment.
Beta glucanase in glycosylated pot acid and calcium after feeding, the enzyme powder into the mash kettle or the preparation dissolved into can glycosylated pot with 20-50 ℃ mashing water.
● The characteristics of the product
Particle the pale yellow solid dosage forms, liquid is red brown liquid. For pH4.0-6.5, the optimum pH is 5, the effective temperature range is 30-70 ℃, the optimum temperature is 60 ℃. To keep the 10min conditions in the above 80 ℃, the enzyme was inactivated.
● Scope of application
This product is suitable for brewing beer, starch processing industry.
● Storage
Products should be sealed storage in a dry, ventilated, cool place, avoid high temperature or direct sunlight insolate, rain, prohibition, and toxic and harmful substances, mixed mixed transport.
● Shelf life
In the fixed storage conditions, the shelf life of solid enzyme was 12 months, liquid enzyme for a period of 6 months.
● Matters needing attention
1, Each open bag or barrel, if not used, should tie the bag or tighten the cover, to avoid damp or pollution.
2, The dust of enzyme sensitive people, inhalation of dust may cause allergic reaction of enzyme. Therefore, recommend the use of solid enzyme preparations, should be operating personnel clothing, wear a dust mask and gloves, don't let the product powder splashing into eyes, mouth, nose, if there is contact, immediately rinse with water.
● Packaging and specifications
Packaging related information, please refer to the standard of the packing list.
