Study reveals significant shelf-life variability in produce among leading grocery stores
The research found that the freshness of produce – specifically strawberries, romaine lettuce and packaged salad mixes – varied significantly from store to store as well as within each individual store.
Zest Labs, San Jose, Calif., released the results of new research study measuring and comparing the shelf life (or freshness) of produce sold at major grocery chain stores across the United States. The research found that the freshness of produce – specifically strawberries, romaine lettuce and packaged salad mixes – varied significantly from store to store as well as within each individual store.
The study, performed from February-May, was based on random samples of strawberry clamshells, hearts of romaine lettuce and packaged salad mixes purchased throughout the research period from eight major U.S. grocery store chains.
