For many, the journey of food from farm to plate remains shrouded in mystery. The intricacies of modern food production, from livestock farming to crop cultivation, are often hidden from the consumer’s eye. This disconnect has fueled the farm-to-table movement, emphasizing transparency and a deeper understanding of the resources, labor, and environmental impact embedded in our meals.
While this movement towards food awareness is commendable, the realm of plant-based meats presents a unique perspective. The necessity for sustainable alternatives to traditional animal products is clear, yet the narrative surrounding these alternatives sometimes fixates on the “how” rather than the “what”—the complex processes like fiber-spinning, air fermentation, and extrusion can overshadow the ultimate question: Does it taste good?
As a tech and food enthusiast, the science is undeniably fascinating. However, amidst the technological buzz at food innovation events, a fundamental question persists: Can this technology deliver delicious food?
This skepticism lingered when the opportunity arose to sample 3D-printed meat from Steakholder Foods, an Israeli food-tech company. Considering the recent plateau in the plant-based meat market, a technological leap seemed necessary to revitalize the sector. The concept of 3D-printing a steak is undeniably intriguing, and these initial tasting samples were presented as exclusive, high-value items. Intrigued, a sample was requested to explore this novel approach to meat alternatives.
Arik Kaufman, CEO of Steakholder Foods, emphasizes that plant-based meats must transcend mere novelty. “You need to eat a product that is amazing,” he states. Steakholder Foods provided a range of their plant-based creations: 3D-printed whitefish fillets, 3D-printed filet steak, and 3D-printed marbled steak, alongside conventionally produced burgers and fish kebabs. Delivered in a medical freight box packed with dry ice, the presentation itself signaled the arrival of a futuristic food experience.
The Promise of Printed Food: Structure and Taste
According to Kaufman, the core advantage of 3D food printing lies in its capacity to construct palatable textures. Steakholder Foods has developed specialized printers – one for fish and one for meat – both utilizing proprietary ingredient blends. The meat printer boasts a production capacity of approximately 500 kilograms of plant-based meat per hour, while the fish printer produces around 100 kilograms.
Following the provided instructions, the 3D-printed whitefish fillet was prepared with a brush of oil and roasted at 180 degrees Celsius (360 degrees Fahrenheit) for 10 minutes. Although the fillet appeared somewhat pale initially, it was cooked longer to achieve a touch of color. Pan-searing might have created a more desirable crust, but concerns about the fillet’s structural fragility led to roasting. These concerns were validated as the delicate fillet partially disintegrated when transferred from baking tray to plate. To compensate for the texture, a vegan lemon butter and caper sauce, along with parsley, was added and the dish was served with couscous.
Steakholder Foods aims to replicate the flaky texture of real fish fillets through 3D printing. However, the tasting experience diverged from this intention. While the cooked fish exhibited a thin, flaky outer layer, the interior possessed a mousse-like consistency, with only a subtle hint of fish flavor.
