Consumers open to eating wasted ingredients, study finds

As we fight back against the rising tide of food waste, a new study has found that consumers would be open to eating a new category of foods created from discarded ingredients.

“There is an economic, environmental and cultural argument for keeping food, when possible, as food and not trash,” said Jonathan Deutsch, one of three Drexel University professors who spearheaded the joint research.

“Converting surplus foods into value-added products will feed people, create opportunities for employment, entrepreneurship and lower the environmental impact of wasted resources.”

American households are estimated to collectively throw away 80 billion pounds of food each year.

Many ingredients are also discarded during the manufacturing process and perfectly edible produce deemed ‘ugly’ doesn’t make it to grocery displays. This all seems to amount to a careless waste when more than 42 million Americans experience food insecurity.

But the big question has been this: Will consumers accept products made from ingredients that were destined for the garbage? Would a person actually eat—and pay for—a granola bar made from spent brewing grains or a relish made from vegetables unfit for the supermarket?

While the macro-economic benefits of value-added surplus products seem clear, the trash-adjacent quality could make people reluctant to consume such products.

Drexel researchers decided to decipher the consumers’ decision-making process to help come up with appropriate communication for these products.

The researchers conducted a series of tests as a first attempt to understand a consumer’s decision-making process with respect to this new food category, value-added surplus foods.

They examined three product cues for value-added surplus products: product description, label and benefit (to self or others).

In the first study, participants were presented with three food categories: conventional; organic and value-added surplus food.

Study participants were presented four different foods using these descriptions.

Participants felt that value-added surplus products were more helpful to the environment than conventional foods, but less helpful when compared to organic foods.

The results demonstrated that participants clearly identified value-added foods as a unique category with unique perception, separate from organic and conventional categories.

Next, researchers tested nine product labels to brand value-added surplus products: upcycled, recycled, upscaled, rescaled, reprocessed, reclaimed, up-processed, resorted and rescued. “upcycled” was observed the most preferred label, followed by reprocessed.

For the final test, the researchers looked into whether a product’s benefit for self or others factored into their feelings. It turned out that participants affirmed that consuming value-added products will generate greater benefits to others than themselves.

The positive findings of this study are of value to sustainability advocates, food marketers and scholars.

By exploring consumer acceptance of and potentially a preference for value-added surplus products, this research marks some of the first attempts to empirically examine a consumer’s evaluation process for this novel food category.

Most importantly, researchers have begun to evaluate how to efficiently present value-added surplus products as a novel category of food to consumers, so that it may contribute some relief to the global food crisis.
