Most realistic’ plant-based steak revealed
Vegan
alternatives to meat are popular but recreating the texture of steak is
challenging
The
“most realistic” plant-based steak to date has been revealed, mimicking the
texture and appearance of a real cut of meat.
The
fake steak’s ingredients include pea, seaweed and beetroot juice, which are
extruded into fine fibres to recreate muscle tissue. Its producer, the Spanish
company Novameat, says the steak will be available in some restaurants in Spain
and Italy this year before scaling up in 2021.
The enormous
impact of cattle and other livestock on the environment has led a
swathe of companies to create plant-based alternatives to meat, with the Beyond
Meat burger and Greggs sausage roll among the vegan successes. But recreating
the texture of whole cuts of meat is far more challenging than ground meat.
“I
started with steak I think because it is the holy grail of plant-based meat,”
said Giuseppe Scionti, founder of Novameat.
“It is the most difficult.” The company unveiled a 3D-printed steak in 2018,
but the new steak has both the firm, fibrous texture and meaty appearance of a
real steak, he said, making it the “most realistic” to date.
The
company is still experimenting with the taste, but Scionti said the company’
can use the ingredients already used to create convincing beefy burgers from
plants. He expects a final formulation in the next few months.
The
key to the new steak is patented micro-extrusion technology that produces
fibres between 100 and 500 microns in diameter. This allows the complex
structure of real meat to be replicated, with muscle fibres and fat entwined.
Existing extrusion technology produces much larger fibres.
The
50g steak produced cost $1.50 (£1.15) to make, similar in price to current
supermarket steak in the UK. But Scionti said the cost will drop when the
process is scaled up. The company plans to commission a pilot plant in 2021
which can produce 50kg of steak per hour. But to reach a mass market, the
company plans to licence its technology to existing food manufacturers who can
develop their own recipes.

Some
plant-based alternatives to meat have been criticised for being as high in fat
and salt as the food they are intended to replace. Scionti said plant-based
alternatives do not contain cholesterol or the hormones and antibiotics often
found in real meat. In future, he said, beneficial ingredients such as omega-3
fatty acids could be added.
Novameat
is not alone in developing plant-based steaks, with Israel-based Redefine Meat being a leading
competitor. Unlike Novameat’s product, the Israeli company’s meat has been
publicly tasted, receiving positive feedback, but the firm has not yet revealed
a textured steak.
Others
include Atlast Food, which is
using a fungus fibres to create textures similar to meat, and Emergy Foods. Another Israeli company,
Aleph Farms, has produced a steak
from real beef cells cultured in a laboratory, which, the firm says, will
have a much lower environmental footprint than real meat.
There
is definitely a role for technology that can structure both plant-based and
lab-grown meat into more complex products, said Rosie Wardle, at the Jeremy
Coller foundation and advisor for CPT Capital, which has invested in Redfine Meat. “I’ve
eaten early versions of the Redefine products and they were truly delicious,”
she said.
Novameat
has attracted investment from New Crop Capital, a firm that also invests in
some of the best known
plant-based and lab-grown meat companies, including Beyond Meat, Memphis
Meat and Mosa Meat.
David
Welch, at the Good Food Institute,
which works with scientists and entrepreneurs to create alternatives to animal
products, said: “To meet the growing global demand for meat with more
sustainable plant-based products, we need to deliver the taste, texture, and
appearance that meat eaters want.”
He
said new technologies such as Novameat’s bioprinting are useful: “They give
plant-based meat manufacturers a wider array of tools to mimic all types of
meat and seafood.” Scionti said the company aims to produce pork and salmon in
the future.
Recent
scientific studies have found that huge
reduction in
meat-eating in rich nations is
essential to cut greenhouse gas emissions and fight the climate
crisis.
“We
believe it is important to provide an alternative,” said Scionti, who spent a
decade researching tissue engineering at the Polytechnic University of
Catalonia in Barcelona and other institutions. “This will help in the long term
to decrease the need for land, water, energy and, of course, reduce the
emissions coming from animal agriculture.
“We
want to be better than the other companies,” he said. “But we are all in the
same boat. We want to be remembered for doing something good at this moment
when the planet needs alternatives to meat. ”
