NIR Spectroscopy – Tomato case

In near infrared (NIR) spectroscopy, unique features of the material are being observed by shining infrared light on them. A specific pattern of the light is reflected by the object. And this pattern is unique for each material – like a fingerprint. Infrared light can be detected with infrared detectors. They convert the reflected radiation into an electrical signal.

This is illustrated above: Short-wave infrared light is emitted, and parts are reflected by the tomatoes. This reflection is detected by the infrared detector HertzstueckTM, which is in direct contact with the sample, and converted into a graph. With our chemical know-how, trinamiX can deduct information about the tomatoes, including, for example, the water or sugar content, which helps to determine the ripeness of the tomatoes.
