Leafy greens can last longer thanks to the stickers

Leafy greens are a common ingredient in many healthy meals. But, they often spoil during shipment or on the store shelf. This is part of a bigger problem of food waste. A recent study from a European food tech has shown that its technology can extend the shelf-life of arugula up to 24 days. This solution can impact not only leafy greens but also the fruit and vegetable industries, making a positive impact on the fight against food waste.

Growing concern about food waste is highlighted by the expanding global leafy vegetable market. According to Global "Leafy Vegetable Market" Growth Research 2023-2030, this market was valued at USD 71.56 million in 2022 and is projected to reach USD 95.72 million by 2028. Spinach and arugula, have recently become more popular due to health trends. Demand for fresh, healthy produce continues to grow, highlighting the need for solutions to extend their freshness. According to the study Food Waste and Its Association with Diet Quality of Foods Purchased in South Florida approximately 28% of all food waste is attributed to leafy greens. 

“The technology we developed can address the challenge of leafy greens' perishability. We are excited to share the results of recent studies that showed how our Vidre+™ 1-MCP stickers impacted leafy greens. For example, the regular spinach began yellowing after just 3 days, while the Vidre+™ treated samples showed only minor yellowing after 10 days. That is not all we have conducted numbers of research and Vidre+™ has demonstrated a positive impact on freshly harvested blueberries, raspberries, mushrooms, and more” - says Tim Malefyt, Ph.D., CTO at Fresh Inset.

Freshness protection food tech

The Vidre+™ technology can revolutionize the way we protect fruits and vegetables from going to waste. It uses simple stickers that go inside the packaging to shield fresh produce from the effects of ethylene gas. Ethylene is a natural plant hormone that ripens fruits and vegetables but also causes them to soften and rot. The stickers gradually release a substance called 1-MCP which is widely used in the produce industry. With Vidre+™, there is no need for a 24-hour application in a sealed storage room. The technology is easy to use and affordable. This solution can have a significant contribution to the global food waste battle.

Vidre+™ is already used in Argentina and is awaiting regulatory approval in key food production markets including the Americas. The research on 5 continents proves the solution works on various crops.

Impact on leafy greens

In 2023, researchers from the University of Life Sciences in Bydgoszcz, Poland led a study, commissioned by Fresh Inset, that demonstrated the impact of Vidre+™ technology on leafy greens. 

According to the data, here are the key findings: 

• Shelf-life Extension: Vidre+™ extends Arugula's shelf-life to 24 days and Spinach's to 10 days.
• Quality Preservation: Both greens show reduced wilting, and weight loss, and maintained leaf color and visual quality with Vidre+™.
• Chlorophyll Retention in Spinach: Vidre+™ Treated spinach retains higher chlorophyll levels.
• Improved Visual Appeal: Higher Visual Quality Ratings (VQR) for Vidre+™ treated greens, influencing consumer choices.
• Overall Impact: Vidre+™ application preserved quality and extends the shelf-life of leafy greens during storage and transport.
