High Temperature Alpha Amylase Brewing Enzymes Non - GMO For Soy Sauce Brewing
A robust and cost-effective high-temperature almylase
produced from non-genetic modified strains of Bacillus licheniformis
enables better liquefaction and fermentation efficacy
LIQMEI FD is a heat-stable alpha-amylase produced from non-genetic modified strains of Bacillus licheniformis through submerged fermentation and refining extraction processes. It is an endoamylase that can rapidly decrease the viscosity of gelatinous starch solution by randomly hydrolyzing starch, glycogen and its degradation products within the α-D-1, 4 glucosidic bonds to produce soluble dextrins and oligosaccharides.
With its robust alpha-amylase activity and superior pH stability, LIQMEI FD has found it wide application in the production of potable alcohol and brewing.

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 andFigure 4).

The exact temperature optimum depends on actual conditions including pH, substrate concentration and processing time.
CONCENTRATION OF CALCIUM:
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.
