Pre-harvest treatments for shelf-life extension and nutrient preservation of fresh produce
23 July 2026
This technology combines innovative pre-harvest treatments using specialised LED light recipes and natural biostimulants to extend the shelf-life and preserve nutritional quality of Asian leafy vegetables grown in controlled environments.
Technology Overview
The solution addresses the critical challenge of post-harvest losses in Singapore's food supply chain, where approximately one-fifth of fresh produce is lost annually. By optimising growing conditions just before harvest, this approach enhances the plant's natural ability to maintain freshness and nutritional value during storage and distribution, reducing the need for additional post-harvest treatments.
Technology Features
Use-efficiency LED light recipes that precisely control light quality, intensity and duration during the pre-harvest phase, optimised specifically for Asian leafy greens to enhance their post-harvest quality
Natural biostimulant formulations using Ascophyllum nodosum (brown seaweed) extract, applied through the hydroponic nutrient solution to strengthen plant cellular structures
Advanced controlled environment systems that enable precise application of both treatments under optimal conditions
Scientifically validated protocols for timing and dosage of treatments to maximise effectiveness
Non-chemical approach that maintains food safety while improving product quality
Demonstrated ability to increase yield, delay leaf senescence and maintain nutritional quality during storage
Potential Applications
Indoor vertical farms and controlled environment agriculture facilities growing Asian leafy vegetables
Hydroponic greenhouse operations seeking to differentiate their products through extended shelf-life
Fresh produce distributors and retailers looking to reduce post-harvest losses
Food processing facilities requiring longer-lasting fresh ingredients
Research institutions studying plant responses to pre-harvest treatments
Benefits
Increases yield by up to 20% through enhanced growth and improved crop quality
Maintains nutritional quality and freshness for longer periods without chemical treatments
Lower resource requirements compared to conventional post-harvest preservation methods
Easily integrated into existing controlled environment growing systems
Environmentally sustainable approach using natural biostimulants
Scientifically validated through proteomics and metabolomics analysis
Commercialisation
The technology is available for licensing and deployment.
