Strategies to improve sales of imperfect carrots

The study measured consumers' responses to hypothetical shopping scenarios for carrots. Participants were most open to buying bunches containing imperfect carrots after being presented with both of those marketing messages promoting ugly carrots' personal and societal benefits. Either message alone was not effective at convincing consumers to buy misfit carrots.

Findings also showed that respondents were willing to pay, with a small discount, for some level of mixed bunches containing both ugly and standard carrots, maxing out at 40% of misshapen carrots -- a sign to regulators who set the tolerance level for cosmetic standards that such a practice could be profitable.

One 2018 study in North Carolina suggested that about 41% of unharvested food is edible but unmarketable because of its appearance. The researchers are assessing ways to "win" with ugly foods in the marketplace by testing consumer acceptance of imperfect foods that don't come with a built-in discount -- a tactic used by some brick-and-mortar and online retailers that hasn't had much staying power.

"Any time you codify that cosmetically imperfect produce is somehow lesser, you're stuck selling it for less and therefore you undermine the entire value chain," said senior study author Brian Roe, professor in the Department of Agricultural, Environmental and Development Economics at The Ohio State University.

"We see that once you promote it as being more natural and as reducing wasted food, the discount is less than it otherwise would be -- but there is also a cluster of folks who are actually willing to pay as much or more because they value reducing food waste and they value the fact that it's got just as much nutrition as standard produce."

Roe conducted the study with Danyi Qi and Jerrod Penn of Louisiana State University and Ran Li, an Ohio State PhD student. The research is published online ahead of print in the Journal of Retailing and Consumer Services.

The researchers surveyed 1,300 U.S. residents who shopped and cooked for their households. Participants in the online survey were randomly assigned to receive one or a combination of two marketing messages: ugly carrots' nutritional quality equals that of blemish-free produce, and there are social costs linked to throwing away food with cosmetic flaws.

Participants also selected from images of their preferred 2-pound carrot bunches and price points, with six bunches -- either with or without their greenery attached -- containing 0% to 100% ugly carrots and prices ranging from $2.18 to $1.39 per pound. In another choice test, consumers could select from just two options, a bunch of all standard carrots or all imperfect carrots with or without green leaves attached, in a hypothetical purchase from either a farmers market or a conventional grocery store.

Participants consistently disliked bunches that included any ugly carrots at all, and the amount they were willing to pay for any number of imperfect carrots was always lower than what they'd pay for 100% standard carrots.

But a top contender in terms of profitability for farmers did emerge from the analysis of participant responses: bunches containing 40% ugly carrots and 60% standard carrots with green leaves attached sold at farmers markets where consumers are exposed to the combined marketing messages.

"If you're at a farmers market, you're thinking more holistically, you're not thinking about cosmetic perfection. You expect things to be more 'real,'" Roe said. "So I think then people realize this is what we might expect if we're getting produce directly from a farmer -- there's more room for imperfection because it's probably not interpreted as imperfection. It's interpreted as naturalness."

The research team analyzed the tipping point in consumer willingness to pay that could make harvesting ugly carrots profitable -- an important calculation for farmers who need a positive return on their investment into planting, picking and shipping their crops. The U.S. Department of Agriculture also has a say in the percentage of non-standard produce that can be sent to market -- a limit that may need to be revisited, Roe said.

"We hope these findings will change the viewpoint of the industry. If you want to move into the ugly produce space, you probably need to rebrand it rather than locking in a discount and saying, 'This is ugly food that should be worth less, so let's just lock it in as being an inferior good from the get-go," he said. "There hasn't been a lot of rethinking of standards in light of food waste, so that would be one policy lever that could be re-examined to deal with food waste in the modern era."
