Often foods need to be picked before they are ripe so they will survive the trip to the grocery store. But now, instead of using chemicals to keep them fresh, Tesco has developed a plant perfusion system.
The "plant perf" system will provide cut plants with the nutrients they need to maintain their freshness and nutrients.
The plant stem is inserted into the perf and locked in place. The perf, which is made from corn starch plastic, feeds the plant while it is in transit.
