The Center for Science in the Public Interest (CSPI) has criticized the US Food and Drug Administration (FDA) approval of soy leghemoglobin as a color additive in uncooked ground beef analog products, branding it “barebones.” The industry watchdog claims that the review excluded key endpoints well known to be associated with cancer risk and thus was inadequate under the law. From burgers to sausages and nuggets, meat-alternative products have flooded the market amid the rise in plant-based eating, also increasing the number of newer ingredients that may be consumed by millions of people.

Soy leghemoglobin is a protein that contains heme, a compound also found in red meat (specifically, in the myoglobin in red meat) and blood (in hemoglobin). The ingredient imparts a reddish-brown color but has already been used by Impossible Foods – developer of the plant-based Impossible Burger – as the “magic ingredient” to give an optimized beefy flavor. The ruling was important as it allows the company to now sell raw Impossible Burgers directly to consumers, instead of cooked via restaurants.

The FDA’s approval followed Impossible Foods’ 2018 petition to have the ingredient accepted as a color additive.

Speaking at the time of the review, Dennis Keefe, Ph.D., Director of the Office of Food Additive Safety in the FDA’s Center for Food Safety and Applied Nutrition, said: “We are in the midst of a revolution in food technology that in the next ten years will likely lead to more innovations in food and ingredient production than there have been in the past half-century. As these new products and ingredient sources come to the market, the FDA has a responsibility to provide the appropriate regulatory oversight to protect public health by ensuring that these new foods and food ingredients are safe.”

“Plant-based dietary transformations are among the more powerful strategies in the fight against climate change and biodiversity loss, so long as the right tools are available for consumers. We know that giving up meat is actually a very big and difficult change for consumers. That’s why we’re creating delicious meat from plants that doesn’t require compromise on taste, nutrition, or culinary experience,” Rebekah Moses, Head of Impact at Impossible Foods, tells NutritionInsight.

However, another primary driver for consumers reducing their meat intake is health. Yet, many meat-alternative products on the market may not be as natural as consumers assume them to be. Burgers such as Beyond Meat and Impossible Foods are, arguably, highly processed and scientifically engineered. Both contain over 20 ingredients each.

“Although they may be better for the planet, many consumers are really surprised to learn that products like the Beyond Burger and the Impossible Burger are no healthier than beef burgers,” Lefferts says. “Meatless burgers served at restaurants generally aren’t any healthier from a nutrition standpoint than the meat versions. They may well be better for the planet, which serves our health in a different way. But, since companies profit from misperceptions that their products are healthier than they really are, I wouldn’t hold my breath waiting for them to set the record straight.”

But despite burgeoning health concerns, the space has caught the eye of heavyweight protein and meat companies.

Only last week, Cargill ramped up its interest in Puris, the largest North American producer of pea protein and a key supplier to Beyond Meat, with an additional US$75 million investment.

Meanwhile, food industry giant Nestlé invested in its own plant-based range in Europe with its new “cook from raw” Garden Gourmet Incredible Mince and a new and improved version of its Garden Gourmet Incredible Burger.

Pork heavyweight Smithfield Foods also launched a soy-based protein portfolio under its Pure Farmland brand in August.

Clearly, the business side of the meat-alternatives space is booming. Innova Market Insights data shows that there has been a 45 percent average annual growth of food & beverage launches with a vegan positioning (CAGR, 2013-2017). New launches with a vegan positioning increased their market penetration in Europe from 1.5 percent in 2013, to 7 percent in 2017.

The nutritional profiles, as well as engineered profile of many of these ingredients, will continue to attract industry attention – and will surely be a space to watch.
