タイトルまたは説明

High temperature alpha amylase enzyme,
food additive, wine making.

Brief introduction
 
GR-M**4 is a fungal α*-‐amylase, which is produced by Aspergillus oryzae var fermentation action, via purification and refine. The enzyme can be not only used for gelatinization (liquidation) of starch, but for saccharity (produce malt syrup).
 
The amylase is called incision enzyme, which can hydrolyse α*1,4 glucoside bond of gelatinized starch, amylose, branch-chain starch solution, to produce soluble dextrin, meanwhile a small number of maltose and glucose. If proceed hydrolysis reaction use GR-M**4 for long time, there will produce syrup containing high maltose and a bit glucose. The syrup have low-hygroscopicity, difficult to crystal and high level fermentability.starch molecular, reduce viscosity of gelatinized starch, to produce soluble dextrin and oligosaccharide.
 
Typical properties
 
Appearance amber to brown solution
Activity ≥*9,**0 u/ml
pH 5.**6.5
Proportion about 1.*1g/ml
 
Enzyme activity unit definition: 
 
Under specific analyze conditions, 1 g solid enzyme ( or 1 ml liquid enzyme) can liquify 1.0g definitive soluble starch substrate in one hour. Assay method is on the basis of QB *********1.
Application 
 Effect of PH 
  • Optimum PH range: 4.**5.4
  • Effective PH range: 4.**6.6
  • GR-M**4 will be the most stable at PH6.**-‐8.0.
  • If the stability of enzyme is an important factor in operation, reaction should be done above PH 5.5, and below PH 5.5 if improved reaction rate.
  Effect of temperature
GR-M**4 can be effectively hydrolyse starch in a range of ***-‐*5℃ with the optimum temperature of *0℃. If the concentration of starch is too high, operating temperature can be increased to *5℃. The optimum temperature will be changed at ***-‐*5℃ affected by PH.
 
Dosage 
 
Dosage is determined by technology conditions generally. Under normal conditions, reaction rate will be improved with the increase of enzyme concentration.
 
Dosage of GR**0 is 0.***0.*5% of dry materials which can liquify and saccharify starch under optimized condition. Recommended dosage is *******0ml/t drys.
 
  Enzyme inactivation
  1. Increase temperature to ******0℃, and keep ****0 minutes.
  2. Decrease PH value to below 4.0, adjust temperature and PH.
  Enzyme inhibitor
  • Heavy metal ion can inhibit activity of GR-M**4, particularly is copper and lead.
  • Zinc, nickel and ferric ion also can play inhibiting effect in high concentration.
Packaging 
 
The product is packed in *0kg food grade polyethylene drum. Large package also can be provided.
 
Security & usage of enzyme
 
Avoid inhaling enzyme dust and enzyme fog. Please rinse with water more than *5 minutes if splash to hands or eyes carelessly. For details, please see individual security data.
