Other claims from this paper (13)
- Intervention effect Dark storage had the highest moisture loss, 22.8%, by Day 18.
- Intervention effect The 530 nm LED treatment had the lowest moisture loss, 8.3%, by Day 18.
- Intervention effect Dark storage caused the greatest color change, Δ E = 7.30.
- Intervention effect Overall visual quality under darkness fell below marketability by Day 6.
- Intervention effect All LED treatments preserved spinach marketability until Day 10.
- Intervention effect The 530 nm LEDs produced the highest overall visual quality scores.
- Intervention effect Mixed-green LEDs increased anthocyanin content by 46.9% against darkness.
- Intervention effect Total phenolics were higher under 530 nm LEDs than initial values, without significant differences.
- Intervention effect Total phenolics were higher under mixed-green LEDs than initial values, without significant differences.
- Intervention effect Mixed-green LEDs produced the highest flavonoid content.
- Observation Chlorophyll and carotenoids remained stable across treatments.
- Association Moisture loss was negatively correlated with overall visual quality (r = −0.735).
- Recommendation The authors suggest low-intensity green LEDs in display fridges to maintain spinach appearance, nutrition and shelf life.
