CHICAGO – Healthy and flavorful ingredients, sustainability and value are among the top trends set to shape the foodservice industry next year, according to a new report from Technomic.

Restaurant operators increasingly will look to new natural resources for menu innovation. This includes previously overlooked parts of familiar plants like beet greens, sweet potato leaves and avocado blossom, which can be positioned as waste-reducing and environmentally conscious. Seaweed and sea beans also will become more popular, as will new oat, fruit and vegetable milks.

New or overlooked plants also will drive a shift away from warm color foods like yellow turmeric, orange wine and red chili.

New greens, including broccoli rabe, celtuce, kale hybrids and komatsuna top Technomic’s list of trending ingredients for 2020. Interest in blue plants like spirulina and butterfly pea is expected to grow, along with purple variations of common vegetables and herbs like corn, broccoli, snap peas, basil and potatoes.

Demand for interesting, healthy ingredients is fueled by a growing consumer appetite for plant-based offerings and adventurous flavors. Concerns about the environment also play a role.

“Sustainability is more than a menu initiative,” said Aimee Harvey, managing editor at Technomic and author of the 2020 trends report. “It’s emerging as part of the food service industry’s new circular economy, evolving from a linear approach of create-use-recycle to create-use-reuse-sustain.”

Technomic anticipates an even greater emphasis on reusable cups, portion control, strawless lids, smaller napkins, wood-fiber utensils, traceable sourcing and compostable packaging next year.

Rather than waiting for trends, Technomic said restaurants — including large chains — will seek to capitalize on fast-moving fads.

“Expect head-scratcher fare such as Asian cheese tea, huitlacoche (corn smut), edible insects and technically illegal tonka beans and C.B.D. to find momentum,” Harvey said.

Creative menu offerings may help operators drive in-store traffic, which has lagged in recent years. As off-premise orders continue to flourish, Technomic said restaurants will turn to special value deals and loyalty-based rewards to drive in-store business.

A potential recession looming on the horizon makes emphasizing value even more important. The prospect of an economic downturn already is leading consumers to be more cautious with their spending, the report said. Thirty-eight percent of economists said the United States is headed toward a recession next year, while 41 percent predict a recession will hit in 2021, according to Blue Chip Economic Indicators. Risks to the economy include the ongoing trade war with China, stalled growth in the European Union and declining corporate profits.

“Expect a back-to-basics mentality to bubble up, as consumers increasingly trade down to lower-priced occasions across foodservice segments,” Harvey said. “Operators who’ve already learned the hard lessons of 2008 will communicate a more direct value story.”
