Product Description
100ml High Temperature Alpha Amylase Enzyme For Potable Alcohol And Brewing
USAGE GUIDELINES
For industrial application of one-time spray liquefaction, first prepare 30∼35% w/w starch slurry, adjust pH 5.8 to 6.5, add calcium ion 50∼70 ppm (dry solids basis), and then add this product. Liquefy at 105∼110°C (221∼230°F) for 5 to 7 minutes, flash cooling down to around 97°C (207°F), keep on liquefying at a temperature above 95°C (203°F) for 90 to 120 minutes so as to reach required DE value. If calcium ion concentration in tap water is already sufficient, it is no need to add calcium.
The actual dosage of LIQMEI FD depends on the actual situation including application fields, starches, substrate concentration, temperatures, pH and other processing conditions. To optimize the dosage, it is recommended to conduct a number of liquefaction trials prior to the routine use of LIQMEI FD.
The presence of calcium is helpful to increase the thermal stability of this enzyme. LIQMEI FD requires a very low calcium concentration of 50∼70 ppm (dry solids basis) to ensure its stability.
Copper, titanium, and cobalt ions are moderate inhibitors for LIQMEI FD, whereas aluminum, lead and zinc ions are strong inhibitors.
PRODUCT CHARACTERISTICS
| Declared Enzyme: | Alpha-Amylase |
| Systematic Name: | EC 3.2.1.1, 1,4-α-D-glucan glucanohydrolase |

EFFECT OF PH
LIQMEI FD is active over a wide range of pH, depending on the actual application conditions. Its optimal pH ranges from 5.8 to 6.5. At a temperature of 25°C (77°F), its stable pH range is 5.0 to 10.0 (See Figure 1 and Figure 2). The actual pH optimum depends on actual conditions including temperature, substrate concentration and processing time.
EFFECT OF TEMPERATURE
Optimum temperature of LIQMEI FD for interval liquefaction is 85∼90°C (185∼194°F). It liquefies starch substrates efficiently at 95∼97°C (203∼207°F) and remains highly active at 100°C (212°F).
LIQMEI FD demonstrates exceptional thermal stability at temperatures from 105∼110°C (221∼230°F), maintains its stability for 5 to 7 minutes and keeps on liquefying efficiently. At a temperature above 105°C (221°F), the enzyme stability decreases rapidly (See Figure 3 and Figure 4). The exact temperature optimum depends on actual conditions including pH, substrate concentration and processing time.
PACKAGING, STORAGE & SHELF-LIFE
LIQMEI FD is packaged in 25kg, 30kg food-grade HDPE plastic drums or 1125 kg IBC totes.
Customized packaging is available upon request.
Typical shelf-life is six months if this product is stored below 25°C (77°F) in its original packaging, sealed and unopened, protected from direct sunlight.
Its shelf-life will be eighteen months if it is stored properly at 0∼10°C (32∼50°F).
LIQMEI FD has been formulated for optimal stability. Prolonged storage and/or adverse conditions such as higher temperatures may lead to a higher dosage requirement, and should be avoided.
SAFE HANDLING OF ENZYMES
Inhalation of enzyme dust and mists should be avoided. In case of contact with skins or eyes, promptly rinse with water for at least 15 minutes. For detailed handling information, please refer to the Safety Data Sheet.
