Can Spectroscopy Help Detect Food Contamination Earlier?
The 2026 Cyclospora outbreak linked to iceberg lettuce highlights a persistent challenge in food production: contamination can move through the supply chain before conventional testing identifies a problem. Emerging research suggests that NIR, Raman/SERS, chemometrics and machine learning may provide food producers with additional tools for faster screening and earlier investigation.
Predicting Avocado Ripeness with NIR Spectroscopy
Knowing when an avocado is ready for market can be challenging without cutting into the fruit. This application demonstrates how near-infrared spectroscopy and chemometric analysis can predict avocado ripeness quickly and non-destructively, providing a potential tool for monitoring fruit quality and improving consistency throughout the supply chain.
Taking NIR Spectroscopy to the Strawberry Field
What can spectroscopy reveal about strawberries in the field? This application follows a portable NIR spectroscopy system into a strawberry field to demonstrate how rapid, non-destructive measurements can help evaluate fruit quality and collect valuable data outside of the laboratory.
