Standard maltose syrup and high maltose syrup sit at different points on the same starch-hydrolysis spectrum, and the gap between them reshapes sweetness, crystallisation, colour development and the real cost per finished unit. For manufacturers, the useful question is not which syrup is “better” but which grade matches the process and the label you have already committed to. Where the two grades come from ------------------------------ Both syrups start the same way: a starch slurry from corn, wheat, rice or tapioca is liquefied and then converted with enzymes. The enzyme choice and the degree of conversion determine how much of the starch ends up as maltose (two glucose units), how much as free glucose, and how much remains as larger saccharides. A conventional conversion yields a broad spread with maltose as the leading sugar. Pushing the conversion further, with the right beta-amylase or fungal enzyme system, raises the maltose fraction and suppresses glucose — that is how high maltose syrup is made. Reading the difference on a specification ----------------------------------------- The table below summarises the commercial ranges most suppliers quote. Exact figures vary by producer and by the starch source, so treat these as indicative and always confirm against a current certificate of analysis.

That is the headline benefit. The subtler one is browning. Glucose and other reducing sugars drive the Maillard reaction, so a high maltose grade with less free glucose usually browns more slowly at the same oven or kettle temperature. For pale baked goods and clear candies, that difference in colour is often worth more than the sweetness saving. Crystallisation cuts both ways ------------------------------ High maltose syrup is more prone to crystallising than a glucose-heavy syrup, which surprises buyers who assume “high purity” means “easy to handle”. In some traditional confections that controlled crystallisation is the whole point — it creates the short, grainy bite the product needs. In clear hard candy, glazes or beverage syrups, the same tendency becomes a defect. If your process involves holding tanks and cold storage, test the grade at your real working temperature before scaling up. Matching grade to application ----------------------------- - **Hard candy and taffy:** standard grade for balanced sweetness and manageable crystallisation; high maltose where low colour is critical. - **Bread and cakes:** either grade supports moisture retention and softer crumb; high maltose favours a lighter crust. - **Brewing and fermentation:** high maltose syrups offer highly fermentable sugars for adjunct use. - **Frozen desserts:** choose the grade by the freezing-point shift you need, not by price alone. - **Traditional fillings and snacks:** high maltose for the characteristic chewy, glossy texture. **Buyer tip:** request maltose percentage, glucose percentage, DE, dry solids and colour on the same certificate. A quote that gives only “Brix” hides the numbers that decide your formulation. Procurement points that prevent reformulation --------------------------------------------- Beyond the composition figures, lock down moisture and dry solids so dosing stays repeatable, sulphur dioxide residue if your product is sulphite-sensitive, pH for dairy and beverage blending, and microbiological plus heavy-metal limits. Ask whether the supplier holds the grade consistent batch to batch, because drifting from 50% to 65% maltose mid-contract is a silent recipe change. For logistics, typical formats run from 280–300 kg drums through 1,000 kg-plus totes to 20–25 tonne flexitanks, with the packaging decision usually driven by how quickly your plant can consume a container. Frequently Asked Questions -------------------------- Is high maltose syrup just a purer version of standard maltose syrup?Not exactly. It is produced by driving the enzymatic conversion further, which raises maltose and lowers glucose. That shifts sweetness, browning and crystallisation behaviour, not only purity. Can I swap standard and high maltose syrup without changing my recipe?Rarely one to one. The two grades differ in sweetness and in how strongly they crystallise, so most manufacturers run a small trial batch and adjust sugar solids or water before committing. Why does my supplier’s maltose percentage move between lots?Starch source and enzyme conditions both influence the profile. Reputable producers hold a tight band and state it on the certificate; if the figure swings widely, ask what control limits apply. Which grade should a first-time buyer sample?Start with the grade that matches your intended application and request both if the product is borderline. A 100–200 kg trial is far cheaper than reformulating after a full container arrives.
