Zest Labs’ Research Measures and Compares Freshness of Strawberries, Romaine Lettuce and Salad Mixes Purchased at Leading Grocery Stores
SAN JOSE, Calif. – June 10, 2019 – Zest Labs™, an AgTech company modernizing the post-harvest fresh food supply chain, today released the results of new research study measuring and comparing the shelf-life (or freshness) of produce being 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. This shelf life variability causes early spoilage, which can disappoint consumers and result in costly retail waste. Zest Labs is a wholly-owned subsidiary of Ecoark Holdings, Inc. (OTCQX: ZEST).
The study, performed from February to May of 2019, 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.
“Zest Labs’ methodology for determining shelf-life is based on years of university research on the effect of environmental conditions on the quality of fresh fruits and vegetables,” said Dr. Cecilia Nunes, Ph.D., Associate Professor at the University of South Florida, Department of Cell Biology, Microbiology and Molecular Biology. “Major universities including University of Florida and University of South Florida have confirmed that this approach is scientifically validated and accurate.”
Consumers often have a disappointing experience when purchasing produce that looks good on the store shelf only to have it “go bad” shortly after purchase. This problem occurs because, due to harvest conditions and variabilities in processing and handling, produce spoils prematurely – before the written expiration date. This leads to consumer dissatisfaction and can lead to changed purchasing behavior, wherein consumers choose a new primary grocery store in search of fresher produce.
Key findings from the research included:
- Roughly half of the sample produce (49 percent of romaine hearts, 58 percent of purchased strawberries and 54 percent of packaged salad mixes) spoiled prematurely, based on target shelf-life of the days indicated in the chart below, and could lead to customer dissatisfaction.
- Shelf-life variation of produce within individual stores varied dramatically by as much as 21 days for romaine (store 7), 12 days for strawberries (store 3) and nine days (store 2) for packaged salad mixes. This inconsistent freshness experience could lead to customer dissatisfaction. Several stores sold some produce that had expired or spoiled at the time of purchase (as indicated by a zero minimum shelf-life value).
“Most grocery stores assume that the produce they are receiving has uniform freshness or shelf-life, but the data shows there is significant variation in freshness both between stores in a region and within the individual stores themselves,” said Peter Mehring, CEO of Zest Labs. “This shelf-life variability leads to dissatisfied customers who purchase produce that spoils before they can consume it and, as a result, may take their business elsewhere to find fresher, more consistent quality produce.”
Zest Fresh™, from Zest Labs, helps retailers identify and manage fresh food supply chain variability to improve delivered freshness and reduce shrink by 50% or more, while increasing customer satisfaction by ensuring consistency of the freshness and shelf-life of the produce their customers purchase. Zest Fresh provides growers, shippers and retailers with autonomous, end-to-end cold chain visibility for proactive decision making. By intelligently managing the handling and quality of each pallet of produce beginning in the field, Zest Fresh enables seamless matching of the retailers’ freshness needs with the actual produce freshness while monitoring adherence to the grower’s processes.
