Key Findings

  • 01UV-B treatment alone significantly increased total antioxidant capacity (80.4%).
  • 02Combined UV-B and LED illumination, particularly with red light, led to a cumulative increase in total phenolic content (up to 35.2%).
  • 03Visible LED illumination (full white, blue, green, red) increased TPC compared to darkness (14.6-19.7%).
  • 04Softening was accelerated by green and red LEDs when combined with UV-B, but firmness remained above commercial thresholds.
  • 05Anthocyanin content did not show significant accumulation in response to light stimuli.

Application

Design takeaway

Integrate UV-B and specific visible LED lighting into postharvest handling and storage designs to enhance the nutritional value of strawberries.

How to apply

Explore the use of UV-B and specific LED lighting (e.g., red for TPC enhancement) in controlled atmosphere storage or active packaging for strawberries and similar fruits.

Project actions

  • 01Consider how light affects food quality in your design project.
  • 02Investigate different light spectra for specific outcomes.

Method & Evidence

AimTo investigate the impact of postharvest UV-B and visible LED illumination on the physicochemical properties, bioactive compounds, and fungal development of strawberries during storage.
MethodExperimental research
ProcedureStrawberries were subjected to postharvest treatments including UV-B irradiation (10 kJ/m²) and various visible LED light spectra (full white, blue, green, red) for 13 days at 3.3 °C. Control groups received no UV-B and were stored in darkness. Physicochemical attributes, fungal development, total phenolic content (TPC), total antioxidant capacity (TAC), and anthocyanin content were measured.
ContextFood science, postharvest technology, agricultural product preservation
