Urbana, Ill. (U.S.A.) -- As the demand for plant-based meat and dairy options grows, vegan burgers, nuggets, and beverages have been in the spotlight for sustainable protein alternatives. But unlike their meatless burger counterparts, plant-based eggs haven’t received the same attention from researchers — until now.
Enter Da Eun Kim, a doctoral student at the University of Illinois Urbana-Champaign, and Brenna Ellison, a professor at Purdue University. Together, they set out to answer a deceptively simple question: What makes someone willing to purchase a vegan egg?
Their new study is one of the first to examine this question. Using an experimental method known as a vignette design, researchers tested how factors such as price, product type, and setting influence people’s behavior.
“We wanted to measure the consumer's perception about plant-based eggs,” said Kim, who is a graduate student in the Department of Agricultural and Consumer Economics, part of the College of Agricultural, Consumer and Environmental Sciences at Illinois. “A vignette experiment allowed us to create hypothetical scenarios and isolate what consumers really think.”
Instead of directly asking people if they would purchase a plant-based egg, the vignette method asked participants to imagine they were about to eat breakfast. This meal would take place either at home or in a restaurant, and consumers had a choice between scrambled eggs or pancakes made with plant-based eggs.
The results were both surprising and informative.
“We expected the setting to be more important, as we thought the novelty of the plant-based egg product would lead people to want to eat it in a restaurant where chefs know how to prepare the product in a way that tastes good,” Ellison said. “Surprisingly, the location of where you were eating, whether it be at a restaurant versus at home, didn't have as much of an effect as we imagined.”
Additionally, consumers were more likely to purchase plant-based eggs when they were mixed into something familiar, like pancakes, instead of served on their own.
The team also asked participants to rate how plant-based eggs would compare to traditional ones. Unsurprisingly, expected taste and appearance still favor the classic egg. But the plant-based version came out on top for environmental impact and animal welfare. This reflects a broader trend in food science, where ethical motivations are beginning to influence consumer choices.
Does this mean every consumer will want to purchase plant-based eggs? “Probably not,” Ellison said. “However, we did find that consumers who had previous experience trying plant-based eggs were more likely to purchase them compared to people without that experience. This suggests that consumers had a positive experience with the product previously.”
While familiarity with plant-based eggs is helpful, familiarity with the end product, such as pancakes, may also be key. “Introducing them as an ingredient, especially in a product that consumers are comfortable with, is a way to get people over any ‘mental hurdles’ associated with trying plant-based eggs,” Ellison said.
These results offer a clear message for the industry: give people an easy, tasty, and recognizable way to try something new.
“There are still sensory barriers,” Kim said. “I’ve tried the liquid version that comes in a bottle, like egg whites. The taste was different, but I was surprised the texture was very similar to traditional eggs.”
That firsthand experience echoes the study’s findings; while taste and texture still matter, many consumers just need a nudge to take the first bite. And the best way to do that may be through a subtle swap in a familiar dish.
While plant-based eggs might not be ready to replace the classic scramble at every breakfast table, they are finding their niche. Science shows that people may not be ready to eat them plain — but mix them in, make it easy, and meet consumers where they are.
