Comparing Maltase/Glucoamylase Quotes for Maltodextrin and Syrup Lines: A Specification Checklist
Compare maltase/glucoamylase offers for maltodextrin by activity, pH, temperature, dosage, COA/TDS/SDS, pilot validation, and cost-in-use.
Two quotes for the same enzyme can look alike on paper and behave very differently in your tank. This checklist is for procurement, QA and process teams at maltodextrin and syrup plants, and for distributors who compare offers before they commit a customer to a grade. It covers what the activity number really tells you, liquid versus powder, the documents to line up, cost-in-use and a fair side-by-side trial.
Our grade is a brown liquid or light brown powder at 100,000–300,000 U/g, working at pH 4.0–5.5 and 55°C–65°C, in 25 kg drums, 200 L drums or 1000 L IBC; send your product, quantity and destination for a quote.
Why the Headline Activity Number Misleads
Activity is measured under a defined assay: a substrate, a pH, a temperature and a unit definition. Two suppliers can print similar numbers measured in different ways, so a higher figure is not automatically a stronger product. Ask every supplier, including us, for the unit definition and the assay conditions behind the number, and for the lot-to-lot tolerance. Then compare products on the same liquefied substrate under the same conditions. Buying specifications also use the names maltase and glucoamylase loosely; specify the job (releasing glucose from maltose and dextrins), the activity unit and the working window rather than the name alone.
Liquid or Powder
Our grade comes either as a brown liquid or as a light brown powder. Liquid suits plants that meter the enzyme by pump into a tank or a continuous line. Powder suits buyers who weigh additions by hand or blend the enzyme into a dry premix. Whichever you choose, compare offers in the same format, check how each must be stored on your site, and plan stock against the 12-month shelf life.
Documents to Line Up Before the Trial
Ask for the lot COA with activity and appearance, the storage conditions and shelf life, and the handling information your safety team needs before the enzyme enters the plant. If your own customers require statements on origin, allergens or GMO status, raise them at the start: they decide whether a grade can be used at all, so they belong before the trial, not after it.
Cost-in-Use, Not Price per Kilogram
The cheapest drum is not always the cheapest batch. A more concentrated product may cost more per kilogram and still cost less per tonne of product, while a product with variable activity can bring DE drift, longer holding times and rework. Work out the enzyme cost per tonne of dry solids or finished maltodextrin, then add holding time, energy for temperature control, the stop step, QC testing and the cost of an off-spec lot.
Running a Fair Side-by-Side Trial
Use the same liquefied starch, dry solids, pH, temperature and residence time for every candidate, and run your current enzyme as the control. Test at least three dose points per product and sample at fixed intervals. Decide on time to the target DE, the glucose and maltose profile, viscosity, filtration, color and the repeatability of the endpoint, then approve scale-up only after both the analytical and the cost review.
Technical Buying Checklist
Activity value, unit definition and assay conditions. • Format: liquid or powder. • Packs: 25 kg drums, 200 L drums or 1000 L IBC, and how they fit your storage. • Shelf life and storage conditions (12 months for our grade). • Lot COA. • How the supplier tells you about formulation or specification changes.
What to Send for a Quote
Send the product and format, the quantity per order or per year and the destination country. For a trial add your substrate, target DE and process conditions. The minimum order is 25 kg. Distributors and resellers are quoted per order in the same packs.

Frequently Asked Questions
How should we compare two quotes for the same enzyme?
Line them up on the same activity unit and assay conditions, run them on the same substrate under the same conditions, and compare the cost per tonne of product, not the price per kilogram.
Are maltase and glucoamylase the same thing in a purchase specification?
The names overlap in trade use. Specify what the enzyme must do, the activity unit and the pH and temperature window, and confirm them with a trial on your own substrate.
Liquid or powder: which should we buy?
Liquid suits metered dosing by pump; powder suits weighed additions and dry premixes. Our grade is available in both forms.
What packs and minimum order apply?
Packs are 25 kg drums, 200 L drums and 1000 L IBC. The minimum order is 25 kg and the shelf life is 12 months.
