Nutri-FAA GS is an enzyme (EC 3.2.1.1.1,4-α-D-Glucan glucanohydrolase) derived from Aspergillus oryzaevar strain. This enzyme is used for the starch saccharification stage.
Nutri-FAA GS is an endo-amylase that facilitates the rapid and thorough hydrolysis of the interiorα-1, 4 glucosidic bonds of starch, amylose, and amylopectin to produce high amounts of maltose syrup and small amounts of sugar. if the reaction lasts for a longer period.
Nutri-FAA GS is widely applied to food industries such as the production of alcohol, maltose, high maltose, beer, beverage industry, candy, etc.

- pH: 6.0 to 7.0
- Density: ≤1.25 g/ml
Impact of PH on Nutri – FAA GS
- The optimal pH range of this product is from 4.8 ~ 5.4 and starch can be effectively hydrolyzed at a pH range of 4.0 ~ 6.6.
- If enzyme stability is a concern, reactions should be carried out at a pH above 5.5.
- If reaction speed is important, it is necessary to adjust the pH to below 5.5.
- Figure 1 is a diagram of the effect of pH on enzyme activity
Impact of Temperature on Nutri – FAA GS
- The optimal temperature range is 45 ~ 55ºC
- The effective temperature range is 45 ~ 65ºC
- The optimal temperature point of this product is 50ºC
- The optimal temperature range is influenced by pH, within 45 ~ 55ºC

Enzyme Inactivation:
- Inactivation can be achieved by increasing the temperature to 90 ~ 100ºC and maintaining it for about 5 ~ 10 minutes.
- If the content of starch is high, this product can be inactivated by holding the temperature at 80ºC for about 30 minutes, or 70ºC for about 60 minutes.
- If inactivation by high temperature is not desired, the pH can be reduced below 4.
- Enzyme inactivation can also be done by adjusting the pH and temperature to the same.
Usage Content:
In general, dosage depends on desired maltose content and saccharification time, typical dosage of Nutri-FAA GS is between 75-500 grams per ton of dry powder (TDS)
However, the exact dosage of Nutri-FAA GS depends on the actual situation such as starch substrate, liquefaction equipment, processing conditions, etc. To optimize the dosage, it is necessary to conduct some liquefaction testing to find the optimized dosage suitable for each production plant.
Packaging: 30kg HDPE plastic can meet Food-Grade standards.
Storage: Product should be kept at temperatures below 25°C, away from direct sunlight. At this temperature, the product has a shelf life of 6 months. If stored at temperatures below 10°C, the product has a shelf life of 18 months.
Note: Enzymes have enzyme dust. In case of contact with skin or eyes, rinse quickly with water for at least 15 minutes.
Nutri-FAA GS is widely applied to food industries such as the production of alcohol, maltose, high maltose, beer, beverage industry, candy, etc.
