Every syrup manufacturer gets the same call: “We need something sweet that won’t crystallize.” Ten minutes later the real requirement emerges — it is for a sugar-free chocolate bar, or a traditional candy that must never melt, or a soft drink that has to stay crystal-clear at any temperature. The four big syrup families each answer a different version of that question. This guide puts them side by side.
Meet the Four Families
- Maltose syrup — the traditional starch syrup, built around maltose (40–70%). Low sweetness, excellent heat stability, a strong crystallization tendency that traditional Chinese sweets rely on.
- Glucose syrup — the standard corn syrup across DE grades (20–70). Balances sweetness, prevents crystallization and adds body; the default industrial sweetener.
- Fructose syrup — high-fructose corn syrup (HFCS) or fruit-derived fructose. Up to 1.5× the sweetness of sucrose, highly hygroscopic, great in cold beverages.
- Maltitol syrup — a sugar alcohol (polyol) that looks and behaves like syrup but is sugar-free, non-cariogenic and lower in calories; the base of sugar-free confectionery.
The Four Metrics That Decide
- Sweetness: how much you need to dose, which drives both taste and cost.
- Crystallization: whether the syrup stays smooth or wants to form crystals — a feature in some products, a flaw in others.
- Hygroscopicity: how eagerly the syrup absorbs moisture from the air; it decides shelf softness — and soggy packaging.
- Heat stability: whether the syrup browns, caramels or holds colour under processing and baking temperatures.
Side by Side
| Property | Maltose syrup | Glucose syrup | Fructose syrup | Maltitol syrup |
|---|---|---|---|---|
| Relative sweetness | ~0.4–0.5 | ~0.5–0.8 | ~1.2–1.5 | ~0.7–0.9 |
| Crystallization | Strong | Low–moderate | Very low | Low–moderate |
| Hygroscopicity | Moderate | Low–moderate | High | Moderate |
| Heat stability | Excellent | Good | Moderate | Good |
| Sugar-free | No | No | No | Yes |
| Relative cost | Low | Low–moderate | Moderate | Higher |
| Flagship use | Traditional sweets, bakery | Candy, jams, beverages | Cold drinks, ice cream | Sugar-free confectionery |
Sweetness Is Not Just Sweetness
Numbers only tell part of the story. Fructose delivers sweetness quickly and intensely; maltose is sweet in a slow, mellow, almost savoury way; maltitol carries a slight cooling sensation. In blends, syrups create synergy — a 50/50 glucose/fructose mix can taste sweeter than either alone. That is why experienced formulators blend rather than choose, and why you should ask for taste-matched counter-samples, not just spec sheets.
Match the Syrup to the Product
| Product | Best syrup | Why |
|---|---|---|
| Hard candy | High-maltose glucose syrup | Controls crystallization, stable at high boil |
| Traditional Chinese sweets | Maltose syrup | The crystallization and low sweetness are the point |
| Carbonated soft drinks | Fructose syrup | High sweetness, no gritty residue, cold-stable |
| Sugar-free chocolate bar | Maltitol syrup + powder | Sugar-free, good heat stability |
| Jams and jellies | Medium-DE glucose syrup | Prevents crystallization, improves clarity |
| Bread and cakes | Glucose or maltose syrup | Moisture retention, softer crumb |
Ask the Supplier These Questions
- What is the exact DE, Brix and sweetness profile of this lot?
- Does the syrup contain sulphur dioxide or other processing aids I must label?
- What is the crystallization onset temperature in my storage conditions?
- For maltitol: what is the maltitol purity, and does it meet the destination’s sugar-alcohol labelling rules?
- Can you supply taste-matched counter-samples of two families for a direct blend trial?
- What are the minimum order quantities across drums, IBC totes and ISO tanks?
The Bottom Line
Choosing a syrup is a trade-off across sweetness, crystallization, moisture behaviour and cost — and the right answer depends on the product, not the habit. Map your application against the table above, run a blend trial, and let the counter-sample settle the argument. The flagship of our line is maltose syrup, but the honest answer is often a blend.

Frequently Asked Questions
How do maltose, glucose, fructose and maltitol differ?
They differ in sweetness, crystallisation behaviour, moisture handling and cost, so the right choice depends on the application.
What metrics decide syrup selection?
DE value, Brix, sweetness profile and crystallisation tendency are the four numbers that guide formulators.
How is sweetness perceived beyond the number?
Fructose tastes quickly and intensely, maltose is slow and mellow, and maltitol adds a slight cooling sensation, so taste trials matter.
