Key Findings
- The study by Kansas State University evaluated CO2 laser-labeling technology (LLT) on 'Red Delicious' apple, green bell pepper, and cucumber
- Laser-engraved produce experienced higher fresh weight loss compared to untreated produce
- There was no observable difference in visual quality between laser-labeled and untreated produce
- Text-labeled produce had higher E. coli contamination than untreated produce, while QR-coded produce had similar contamination levels to controls
