3D-Printed Plant-Based Meats Head to US Grocery Stores Amid Nutrition Debates

POLICY WIRE — Washington, United States — American consumers could soon find 3D-printed food products on supermarket shelves, although questions regarding their long-term nutritional value persist among experts. Steakholder Foods, an Israel-based technology firm utilizing 3D printers to manufacture plant-based meat and fish, announced plans last month to introduce its brand, Perfecta, to retail locations across the Northeast.

The upcoming product lineup features Perfecta chicken breast, filet mignon, marbled steak, salmon patties, and white fish patties. According to the company, these items are manufactured using advanced 3D printing technology alongside a blend of plant-based and cultivated ingredients, paired with precise culinary techniques designed to replicate the sensory experience of conventional meat.

Because these items are constructed from standard ingredients, they taste comparable to regular food items, while their main distinctions lie in appearance and texture. Chefs and food producers utilize the machinery to execute creative liberties that would otherwise remain unachievable through traditional manufacturing methods.

Companies are interested in providing new, interesting textures and shapes that can’t be achieved by the normal extrusion process, so the novelty of 3D-printed shapes is the main draw for consumers, explained Dr. Bryan Quoc Le, a food scientist and author.

In an official news release, Steakholder Foods stated its intention to tackle persistent consumer challenges within the plant-based sector, specifically targeting taste, texture, and the authentic experience of enjoying a whole cut of meat. While the firm did not disclose exact geographic locations for the U.S. rollout, Perfecta packaging currently omits any indication that the items were manufactured using a 3D printer.

Popular plant-based meat substitutes like Beyond Beef and faux chicken have generally been accepted as components of a healthy diet, with Harvard experts suggesting alternative meats offer superior nutritional profiles compared to red meat. However, Megan Wroe, a registered dietitian at Providence St. Jude Medical Center, noted that because 3D-printed iterations remain relatively novel, comprehensive research evaluating potential positive or negative health outcomes is currently lacking.

What little research there is shows macronutrients like protein, fat and fiber can be pretty well controlled in 3D-printed foods, but the jury is still out on micronutrients like vitamins and minerals and how well they show up in 3D versions, Wroe stated.

Perfecta’s website outlines that its offerings utilize high-quality plant proteins including soy and pea, natural fats, and various flavor enhancers to mirror meat textures and tastes, while cultivated variants integrate cultured cells to mimic traditional characteristics. Quoc Le pointed out that while ingredient profiles resemble standard alternatives, 3D printing often demands specific additives.

An example is that there used to be some interest in 3D-printed shapes using pasta, chocolate, or sugar, which are fairly basic and can possess enough structural integrity to be printed, Quoc Le noted. For something like a plant-based meat, there may be additives included to make sure the material survives the 3D printing process.

Additional concerns surrounding products from brands like Perfecta center on their reliance on ultra-processed components. Wroe expressed caution regarding the presence of soy flour, rapeseed oils, binding agents, and flavorings found on product labels.

While the macros all look pretty well, these are ingredients I tend to steer my clients away from as they lack micronutrient quality, Wroe remarked, noting that despite novelty, certain populations might experience distinct advantages from these grocery additions.

A population I can say with confidence that definitely benefits from 3D foods are those with dysphagia, Wroe explained, referencing the medical term for swallowing difficulties. Such items would enable patients dealing with this condition to encounter greater dietary variety and make their meals look and feel like real meals rather than soups or purees, which of course enhances their meal experience and well being.

Individuals residing in designated food deserts represent another demographic that could potentially gain access to essential nutrients previously out of reach through these commercial offerings. Outside of those with dysphagia or significant food access barriers though, I don’t know that anyone should be incorporating 3D foods into their diets, Wroe cautioned.

Again, I am incredibly skeptical about the nutritional impact of these hyper-processed foods and have not seen any research as of yet that builds my confidence in recommending 3D foods as a regular part of a balanced diet, the dietitian concluded.
