Taking Food Analysis Out of the Lab, March 2026

Food suppliers are under pressure to demonstrate quality and safety faster, with less waste and at lower cost. Traditional destructive testing, based on sending samples to a central lab, struggles to keep pace with tighter regulation and shrinking margins. As a result, many producers are now exploring rapid, non‑destructive spectroscopy that can be deployed at the point of harvest, intake or processing.

Portable near‑infrared (NIR) and short‑wave infrared (SWIR) instruments make it feasible to move measurements out of controlled laboratories and onto factory floors, into grain silos or even out to fishing vessels. Instead of having to send samples back to a laboratory and cutting, juicing or otherwise destroying them, operators can quickly probe internal quality through the skin or shell of a product in the field, or on the water.

Compact NIR/SWIR Modules for Real-World Use

This transition depends on optical hardware that is compact, robust and sensitive enough to deliver reliable spectra in demanding environments. Recent generations of miniaturised spectrometers, such as OtO Photonics’ RedBullet, GoldenBullet and SideWinder modules distributed by AP Technologies, cover the 900–2500 nm range in integration‑ready formats.

Unlike bench‑top instruments, these modules are designed for handheld analysers and in‑line sorters, combining low noise with high stability. That allows instrument builders to embed NIR/SWIR analysis into scanners, hoppers and conveyors without compromising measurement performance.

From Fruit Ripeness to Toxin Detection

Practical deployments show how much value this approach can unlock for food producers and processors. Researchers have used these modules to build non‑destructive models for total soluble solids and acidity in fruits such as mangoes and pineapples, improving ripeness grading and automated sorting. In seafood safety research, the SideWinder SW2520 has supported work on detecting toxins in mussels, contributing to faster, more reliable screening.

Laboratories and industrial users also exploit the extended 2500nm range for tasks such as monitoring oil oxidation, tracking protein content and measuring grain moisture and meat protein levels. The same core hardware can serve multiple chemometric models, so one platform can support several different product lines.

Engineering the Complete Solution

For many equipment manufacturers, the optical module is only part of the challenge. Selecting a suitable wavelength range, ensuring mechanical robustness and integrating data capture and processing into existing software can add significant hidden engineering cost.

To address this, OtO Photonics supports its modules with a software development kit that lets engineers control the spectrometer and acquire data without writing low‑level communication code. That shortens prototyping cycles and allows teams to focus on application‑specific algorithms, whether for grading fruit or classifying contaminated shellfish.

AP Technologies works with instrument designers to align module choice and configuration with the intended environment and measurement task, from rugged handhelds to automated lines. By pairing three decades of experience with proven NIR/SWIR hardware and software tools, they help system suppliers move quickly from promising lab results to reliable commercial instruments.
