Glucoamylase

One.Product presentation Glucoamylase is extracted from the fermented deeply excellent Aspergillus niger.It can start from the non-reducing end of starch molecule to decompose and transferAlpha-1,4 glucose glycosidic linkage to gulcose.It can be used extensively in beer brewing,alcohol,monosodium glutamate,starch sugar,antibiotics,etc. Two.

Beer brewing This product can be added before fermentation and saccharification start,which can improve fermentation.Recommended using amount: 0.1-0.25L per ton malt. 2. Alcohol business When the material is boiled and temperature is reduced to 60 centi grade,you can add glucoamylase.Recommended amount:0.4-0.6L unit per ton dry material.Temperature is kept about 30-60 mins,and after temperature of material get cold,you can ferment it. 3. Starch sugar business After this material is liquefied,PH is adjusted to 4.2-4.5,and temperature is reduced to 60 centi grade,and then glucoamylase is added to start to sacharify.Recommended amount: 100-300 u per gram material. 4. Monosodium,Antibiotics business After starch is liquefied and temperature is reduced to 60 centi grade,you can change PH to 4.5,and then add gulcoamylase.Recommended amount:100300 unit per gram material. Five.Package and storage The liquid is packed by innoxious plastic cask( 25kg per cask).The powder is packed as follows:inside package is innoxious plastic bag(1kg per bag),and external package is paper box(20kg). This product must be put in cool and dry place and avoided sunshining.
