Frequently Asked Questions
- What does NIR actually measure in food products?
- NIR spectroscopy measures the absorption of near-infrared light at specific wavelengths corresponding to molecular bonds. For food, this translates to rapid, non-destructive measurement of moisture, protein, fat, fiber, and starch — the compositional...
- Why do food manufacturers prefer NIR over traditional laboratory testing?
- Food manufacturers use NIR because it delivers results in real time while the product is still under your control. Traditional laboratory methods take hours to days — by then, the batch is already packaged. NIR at-line or inline lets you adjust proce...
- Can NIR measure food allergens or contaminants?
- NIR spectroscopy measures composition — moisture, protein, fat, fiber — but not specific chemical structures like allergens or pathogens. However, NIR can detect indirect markers of quality problems: for example, unexpected spectral shifts may indica...
