Bartenders and cocktail enthusiasts know it: proportions matter. A bit too much or slightly too little of an ingredient, and the person drinking will never look back.

The same principle applies to food processing plants, for which getting ingredient levels right can be complicated but nonetheless crucial to keep the business afloat. So far, these producers have mostly operated on a combination of gut feeling and technology capable of identifying the different components in liquid food and beverages. They have known, for instance, how much sugar there was in their products. The composition of this sugar, however, has been unknown.

Days - FT-NIR - Technology - Technology - Light

These days are over. By successfully applying FT-NIR technology – a technology using near-infrared light and algorithms to quantify gas components – to liquids under the FAME (Development and demonstration of an innovative FT-NIR-based system for food content analysis) project, Opsis is now capable of distinguishing ingredients at molecular level.

How is FT-NIR relevant to the food industry?

Dr - Olle - Lundstrom - Technologies - Use

Dr Olle Lundstrom: Compared to technologies currently in use in the food processing industry, which mostly relies on NIR only, FT-NIR provides better resolution. Using it, you can continuously identify small details that had never been captured before on production lines.

FT-NIR has been around for 30 years but has so far been used mainly in laboratories and for industrial applications. With this project, Opsis successfully brought its own FT-NIR Gas technology – used for pollution monitoring – into the food processing industry.

Food - Level

Is it really useful to scrutinise food at the molecular level?

For some market players it won't be interesting, unless they are looking for something very detailed and specific. For example, there are already solutions available to quantify sugar on production lines. You don't need FT-NIR for that.

Technology - Type - Sugars - Product - Thanks

However, no technology can measure what type of sugars are in a product. Thanks to FAME, we can now...
