glucoamylase enzyme

Release date：

2025-07-11

Description

SUPERMEI FD is a high concentration glucoamylase produced from strains of Aspergillus niger through submerged fermentation, extraction and refining processes. It has a high conversion rate from starchy substrates to fermentable sugars. It can hydrolyze α-D-1, 4 glucosidic bonds from the non-reducing end of starch one after another. It can also hydrolyze the α-D-1, 6 glucoside branch bonds of starch and cleaves the α-1, 3 bonds to produce glucose.

With its robust glucoamylase activity, SUPERMEI FD enables higher alcohol yields, faster fermentation and less starch residuals in for the production of alcohol and brewing.

Product Characteristics

Declared Enzyme:	Glucoamylase
Systematic Name:	EC 3.2.1.3, 1,4-alpha-D-glucan glucohydrolase
Appearance:	Yellow brown brown liquid
Activity:	400,000 U/ml (minimum)
Product pH:	3.0 to 5.0
Specific gravity:	≤1.20 g/ml

Effect of pH

SUPERMEI FD works at pH from 3.0 to 5.5 with its optimal pH from 3.5 to 4.5. See Figure 1.

Effect of Temperature

SUPERMEI FD works at temperatures from 30 to 65°C with its optimal temperature range from 55 to 60°C. See Figure 2.

Application and Benefits

SUPERMEI FD is capable to saccharify liquified mash from various sources including corn, milo, barley, wheat, rice, potatoes and tapioca. The resultant glucose product is fermented by yeast or another appropriate microorganism to yield alcohol.

SUPERMEI FD has been designed to ensure the following benefits:

1) Increased fermentation rate

2) Increased alcohol yields

3) Efficient starch/dextrin degradation

4) Less starch residuals in distiller’s grains

5) Improved performance in pre-saccharification processes

For ground-grain processing plants using simultaneous saccharification fermentation (SSF), SUPERMEI FD may be directly added into the fermenter. For ground-grain dry mill plants and for wet mill plants using a separate pre-saccharification step prior to fermentation, SUPERMEI FD may be added to the cooling mash or liquefied starch when the temperature reaches 55 to 60°C. Temperatures above 65°Ccan result in loss of activity.

Dosage Guidelines

In general, SUPERMEI FD is added at a dosage rate of 0.26 to 0.34kg/TDS. The exact enzyme dosage level is dependent on the type of raw materials, processing temperatures, reaction time and pH during the actual saccharification and fermentation process and the desired results in the individual alcohol plants.

Packaging , Storage & Shelf-life

Standard packaging is 25kg, 30kg food grade plastic drums or 1125kg IBC totes. Customized packaging is available upon request.
Typical shelf-life is eighteen months if it is stored below25°Cin its original packaging, sealed and unopened, protected from direct sunlight.
Prolonged storage and/or adverse conditions such as higher temperatures may lead to a higher dosage requirement, therefore should be avoided.

Safe Handling of Enzymes

Inhalation of enzyme dust and mists should be avoided. In case of contact with eyes or skin, promptly rinse with water for at least 15 minutes. For detailed handling information, please refer to the Material Safety Data Sheet of this product.

Glucoamylase enzyme is a highly efficient and versatile biocatalyst widely used in various industries for its ability to break down complex carbohydrates into simple sugars. One of the key advantages of glucoamylase is its ability to work under a broad range of conditions, including moderate temperatures and slightly acidic to neutral pH levels, making it suitable for diverse processing environments.

In the food and beverage industry, glucoamylase plays a vital role in the production of sweeteners, syrups, and fermented products. It is extensively used in the saccharification step of starch-based processes, where it efficiently converts dextrins and oligosaccharides into glucose, enhancing yield and reducing processing time. The enzyme’s high specificity ensures minimal byproduct formation, resulting in purer and more consistent end products. Additionally, its application in brewing and alcohol production improves fermentation efficiency by maximizing sugar availability for yeast, leading to higher alcohol yields and better-quality beverages.

Another significant application of glucoamylase is in the biofuel industry, where it aids in the conversion of starch-rich feedstocks, such as corn and cassava, into fermentable sugars for ethanol production. The enzyme’s robustness and effectiveness contribute to cost-efficient and sustainable biofuel manufacturing. Beyond industrial uses, glucoamylase is also employed in research and diagnostics, particularly in enzymatic assays and biochemical studies involving carbohydrate metabolism.

The benefits of using glucoamylase include its high catalytic efficiency, stability under processing conditions, and compatibility with other enzymes, allowing for synergistic effects in multi-enzyme systems. Its use leads to reduced energy consumption, lower production costs, and improved product quality, making it a preferred choice for manufacturers worldwide. Whether in large-scale industrial processes or specialized applications, glucoamylase enzyme stands out as a reliable and essential tool for starch hydrolysis and sugar production.
