Maltase Enzyme for Maltodextrin Conversion
Achieve high-yield glucose production by converting maltodextrin and maltose efficiently — tailored for beverage, brewing, and sweetener manufacturers.
In industrial carbohydrate processing, residual maltose and short-chain dextrins left in starch hydrolysates can reduce glucose yield, strain downstream efficiency, and impact final product consistency. Maltase enzyme — a glucoamylase derived from Aspergillus niger — resolves this limitation by catalyzing the hydrolysis of maltose and maltodextrin into free glucose. Operating optimally at pH 4.0–5.5 and 55–65 °C, it integrates smoothly into saccharification steps across beverage, brewing, and sweetener production lines. Technical buyers value its high activity range of 100,000–300,000 U/g, consistent conversion under acidic conditions, and scalable bulk packaging options starting from a 25 kg minimum order. By applying accurate dosage, typically 0.10–0.40% on dry solids, plants can raise fermentability for drier beer styles, enhance sweetness profiles in food and drink formulations, and boost glucose output for corn- or wheat-based syrups. Maltase's role is the critical link between starch breakdown and the desired end-quality, whether targeting sports drinks, high-fructose feedstock, or pharmaceutical-grade glucose. The reliable performance and flexibility to fit batch or continuous operations make it a cost-effective solution for processors seeking better yields, predictable outcomes, and dependable industrial supply.
Maltodextrin Conversion
Use maltase enzyme to hydrolyse maltose and short dextrins into glucose in starch hydrolysate lines. This step completes maltodextrin conversion, improves sweetness, and reduces residual carbohydrates before filtration, blending, or crystallisation. Operates effectively at pH 4.0–5.5 and 55–65 °C, with dosage optimised around 0.10–0.40% on dry solids.
Corn Sweetener Production
For glucose syrup and dextrose plants, maltase enzyme supports higher glucose yield from corn starch hydrolysate. It feeds HFCS isomerisation or crystalline dextrose production by converting remaining maltose fractions into fermentable glucose. Available in scalable bulk packaging for consistent industrial performance.
Brewing Attenuation
In brewing, maltase enzyme increases wort fermentability by converting residual maltose and low-molecular-weight dextrins. This supports drier beer styles, faster fermentation, and more consistent attenuation control. Brewers match dosage to extract profile, target gravity, and process conditions.
Baking and Beverage Sugar Generation
In doughs and beverage syrups, maltase enzyme produces in-situ glucose that supports yeast activity, browning, and sweetness balance. It integrates where controlled sugar release is needed without adding extra saccharides upfront. Offered with ISO 9001, Food Grade, HALAL, or KOSHER certifications.

Frequently Asked Questions
What does the enzyme maltase do in industrial processing?
Maltase hydrolyzes maltose and small dextrins into glucose, completing the saccharification of starch hydrolysates. This increases glucose yields, improves sweetness profiles, and enhances fermentability in brewing. Its catalytic efficiency makes it an important step between starch hydrolysis and final product formulation in glucose syrup, brewing, baking, and other carbohydrate-based industrial processes.
What type of enzyme is maltase?
Maltase is a carbohydrase classified as EC 3.2.1.20, functioning as a glucosidase. It cleaves α-1,4 glycosidic bonds in maltose and maltodextrin, releasing glucose units. Industrially, it is often sourced from Aspergillus niger for reliability, food-grade compliance, and strong performance under acidic process conditions.
Is maltase suitable for acidic process streams?
Yes. Maltase from Aspergillus niger works best in acidic conditions, with an optimal pH range of 4.0 to 5.5. This allows smooth integration into processes like brewing, sweetener production, and certain food formulations where acidic environments are common. This minimizes the need for pH adjustment, reduces energy use, and supports consistent process outcomes.
How should maltase enzyme be dosed?
A typical dosage for maltodextrin conversion is 0.10–0.40% on dry solids, or roughly 0.1 to 0.3 kg per tonne of substrate, adjusted for substrate composition, temperature profile, and target glucose yield. Overdosing raises cost without benefit, while underdosing reduces conversion efficiency. Monitoring sugar profiles during trials helps fine-tune the rate.
What is the packaging and shelf life?
Maltase enzyme is available in brown liquid or light brown powder form with a 12-month shelf life. Standard packaging includes 25 kg drums, 200 L drums, and 1000 L IBC, with a minimum order quantity of 25 kg. Store in a cool, dry place away from direct sunlight to maintain activity. Quality certifications include ISO 9001, Food Grade, HALAL, and KOSHER.
