Technology is helping track and monitor perishables from grower to distributor, and on to the restaurant. It is up to restaurant chains to ask suppliers and distributors to implement such technology. IoT sensors, in fact, can go a long way toward this goal, monitoring cooling, freshness and the time it takes for produce to go from field to work. Zest Fresh is an example of a technology solution that’s being deployed to help monitor and ensure freshness going back to the source.
