Quick answer: Rare sugars are sugars found in nature only in small amounts. The best known are allulose (also called psicose) and tagatose. They taste like sugar but provide fewer calories. Food developers sometimes combine them with coconut sugar: the rare sugar reduces total sugar or calories, while coconut sugar adds caramel flavour, colour and a natural sweetener story. Rules differ by country, so check regulation first.
Key takeaways – Rare sugars occur naturally in small amounts and are produced commercially. – Allulose and tagatose are the most common in foods. – Combined with coconut sugar, they can lower sugar while keeping flavour. – Approval and labelling differ by market.
What are rare sugars?
Rare sugars are monosaccharides and related sugars that exist in nature only in tiny quantities, for example in some fruits. Producers make them commercially, often by converting other sugars with enzymes. They look and behave much like sugar, but the body uses them differently, which is why they provide fewer calories.
How do the main rare sugars compare?
| Sweetener | Sweetness vs sugar | Notes |
|---|---|---|
| Allulose | About 70% | Browns readily, keeps products soft |
| Tagatose | About 90% | Browns, clean taste |
| Coconut sugar | Similar to sugar | Caramel flavour, brown colour |
Sweetness values are approximate and depend on the product and concentration.
Why combine rare sugars with coconut sugar?
A rare sugar alone can taste flat, because it has little flavour of its own. Coconut sugar adds depth: caramel, toffee and a warm colour. Together they can give a lower-sugar product that still tastes and looks rich. This approach suits cookies, bars, sauces, ice cream and beverages.
How do you formulate a blend?
- Set the target: lower sugar, lower calories, or both.
- Start by replacing part of the coconut sugar with a rare sugar.
- Check sweetness and adjust, since rare sugars may be less sweet.
- Watch browning: allulose browns quickly, so lower baking temperatures may be needed.
- Test texture and shelf life.
- Confirm labelling and nutrition values for your market.
What about regulation?
Rules vary. In the USA, allulose has GRAS status and the FDA allows it to be excluded from total and added sugars on the Nutrition Facts label, while still counting its calories. In other regions, approval status differs and may still be under review. Always check local regulations before launching a product with rare sugars.
Are there practical limits?
Rare sugars usually cost more than conventional sugars. At high levels, some people may experience digestive discomfort, so many products use moderate amounts. Supply may also be more limited than for traditional sugars. These are reasons why many brands use rare sugars as partners rather than full replacements.
Where does IMC fit?
PT Integral Mulia Cipta (IMC Group) has produced coconut sugar in Central Java since 2012 and exports to customers abroad, including the USA. IMC offers mesh 14 and mesh 50 granules. Developers working on lower-sugar blends can ask the IMC team for coconut sugar samples to test with rare sugars.
