# Sugar Syrup Colour and Purity: Managing Invert and Caramelisation

Colour is the quality signal buyers judge first. In sugar syrup it reflects invert level, storage temperature and process control, so managing colour means managing the whole chain.

Invert and colour
-----------------

Invert sugar is sweeter and more hygroscopic, but excessive inversion or heat drives browning. The target invert level should be specified and controlled, not left to drift.

Storage and heat
----------------

- Store cool to slow colour development.
- Avoid hot spots and prolonged high temperatures.
- Keep tanks clean to prevent contamination.

**Practical tip:** track colour and invert together; a rise in colour usually traces back to storage conditions.

Quality control
---------------

Test each lot for solids, invert, colour and microbiology. For clear beverages and bakery glazes, a small colour shift is visible to the consumer, so it is worth catching early.
