Creating cultured meat sought
by the next generation
Growing Steak Meat in a Lab
Why research on cultured meat is necessary
Increased demand for meat
The demand for meat is rapidly increasing along with the
global population growth and the economic development of
emerging countries. According to the Food and Agriculture
Organization of the United Nations (FAO), demand is expected
to increase 1.8 times by 2050 compared to that of 2007. In
order to meet this growing demand, new alternatives to
traditional livestock meat are necessary.
One such option is cultured meat. It is derived from animal cells
that undergo tissue cultivation outside animal bodies. Cultured
meat is gaining attention worldwide as a sustainable food ingredient,
and the share of meat substitutes including cultured meat in the
meat market is expected to increase.

Environmental impact of livestock meat production
Livestock production requires vast land and a large amount of water, especially when livestock are fed with cereal grains such as wheat and corn. In addition, when cows burp, they release gas containing methane, a greenhouse gas that traps heat from the sun more than 25 times as efficiently as carbon dioxide. Livestock therefore has a serious impact on the global environment.
Sanitary control
Cultured meat is produced by cell cultivation under an aseptic condition in a strictly-controlled sanitary environment. Accordingly, cultured meat has a low risk of bacterial or viral contamination and therefore its food poisoning risk is significantly lower than that of livestock meat.
What is cultured steak meat?
Meat alternatives to traditional animal-derived meat include meat substitutes used for vegetarian foods, plant-based meat alternatives from raw materials derived from plants, and cultured meat produced by tissue cultivation of animal cells outside the body. The level of skills and technology required in research differs depending on the type of meat substitutes. The NISSIN FOODS Group is engaging in the research of cultured steak meat, which requires the most sophisticated level of technology.
Cultured ground meat
Animal cells are cultivated outside the body to produce cultured ground meat. Since it does not have a three-dimensional structure like the muscle tissue of traditional meat, it does not replicate the texture. In the Netherlands in 2013, a hamburger made of cultured ground meat appeared on the market. One major issue was the production cost - around 30 million yen for one hamburger.

The three-dimensional structure of muscle tissue was produced in a laboratory thereby replicating the texture of traditional meat. In this process, it is essential to fuse the cells together and convert them into a long, narrow structure. Even in comparison with cultured ground meat, a significant advancement in technology is required.
Why is the NISSIN FOODS Group carrying out research on cultured meat?

Creating Cultured Steak Meat
The NISSIN FOODS Group began joint research on cultured meat with the University of Tokyo in August 2017, taking on the unprecedented challenge of creating thick cultured steak meat.
Pursuing Food Possibilities Never Achieved Before
Potential of Cultured Steak Meat
The NISSIN FOODS Group established its environmental
strategy EARTH FOOD CHALLENGE 2030 to commence various
initiatives aimed at realizing a sustainable society and
raising corporate value. One such initiative being
undertaken is the creation of cultured steak meat, which is
being carried out by the Cultured Meat Project Team at the
Global Innovation Research Center.
Furuhashi says they are carrying out research day after day to
make cultured steak meat a reality, which no one has ever been
able to do, teaming up with Professor Takeuchi of the University
of Tokyo.
Cultured Meat Research Made Possible Through Collaboration between the NISSIN FOODS Group and the University of Tokyo
Shoji Takeuchi is a professor at the Graduate School of
Information Science and Technology and the Institute of
Industrial Science (IIS), the University of Tokyo. He had
already been undertaking research on the three-dimensional
formation of muscle tissue outside the body. Muscles made
from cultured cells were already used in a wide range of
fields, including drug discovery test models and
next-generation robotic research. Professor Takeuchi says he
was confident that cultured steak meat could be produced by
applying this technology. However, he was unable to secure
proper funding for his research as companies and the
university did not understand the value of his research.
According to Professor Takeuchi, it was around this time that
the NISSIN FOODS Group came to him. Both parties agreed to develop
cultured steak meat together and immediately embarked on joint
research.

Major Step Toward the Commercialization of Cultured Steak Meat
Japan Has the Optimal Environment and Resources for the Research
Japan is already ahead in regenerative medicine and
research on muscle tissue. This nation boasts
highly-advanced technology for building three-dimensional
tissue outside the body. While research on cultured meat
is conducted all over the world, Japan’s technological
prowess offers an advantage in this field.
Professor Takeuchi said that although it is an extremely challenging
goal to create muscle and internal organs, which usually occurs
inside the body, from scratch outside the body, he finds this
challenge fulfilling as a researcher.

Barriers to Research
The texture of traditional meat comes from the
three-dimensional structure of muscle tissue inside the
muscles. Producing this three-dimensional structure outside
the body in a laboratory requires not only an increase in
muscle tissue but also further maturation of muscle cells
(fusing the cells to change them into a long, narrow
structure). However, to mature muscle cells outside the
animal’s body, which differs from the natural process of
muscle cells maturing inside the animal’s body, technology to
ensure that nutrients were absorbed evenly throughout the
muscle cells and to properly align them was required.
According to Furuhashi, this actually was the biggest obstacle
to this research on cultured steak meat.

The First in the World to Successfully Produce Cultured Meat in the Form of a Diced Steak
A research group made up of members from the NISSIN FOODS Group and the Institute of Industrial Science, the University of Tokyo confirmed that injection of Vitamin C to bovine muscle cells during the cultivation process promotes maturation. In addition, three-dimensional cultivation, as opposed to the traditional planar cultivation of bovine muscle cells, was conducted to produce a thick piece of cultured meat. Owing to this, the team succeeded in producing a long, narrow muscle tissue featuring the unique striped sarcomere structure. Furthermore, by stacking the muscle tissue modules and using a special method for culturing, the team succeeded in producing the world’s first large three-dimensional muscle tissue cube (1.0cm x 0.8cm x 0.7cm). This was a significant first step toward the commercialization of cultured steak meat with the same texture as real meat.
Japan’s First Tasting of Cultured Meat by Those Involved in the Research
Traditional cultured meat is not edible because it is made
from muscle cells from beef and inedible material. In
order to produce edible cultured meat, the following two
requirements must be met: utilization of edible
ingredients only and a tasting system in the research
processes.
The research team succeeded in the production of edible cultured
meat by using originally-developed edible serum and edible
blood plasma gel.
Based on this result, we established a process up to tasting
of cultured meat, making use of knowledge and experience of
the NISSIN FOODS Group. As the University of Tokyo Ethics Review
Committee approved the process, the first tasting event took
place in March 2022 by those involved in the research.
Although Professor Takeuchi had expected a slightly softer
texture, the cultured meat actually had a firm and chewy texture.
While it did not exactly have the same taste as traditional
meat, it did contain umami. All in all, he believed the quality
was acceptable for cultured meat eaten for the first time.
Furuhashi found the chewy texture suitable for food. She was
surprised that she sensed a touch of umami although the meat
did not contain tastes derived from meat fat and iron.
Creating Meals of the Future
Striving to Develop Basic Technology in Fiscal Year 2025
The NISSIN FOODS Group aims to establish the basic
technology for cultured steak meat in Fiscal Year 2025.
The Group is moving forward with research to create larger
pieces of cultured meat and to faithfully reproduce the
original taste and texture of traditional meat.
In the future, the cultured meat market has the potential to
grow into a major market as a new meat option. The technology
used to produce cultured meat is also not limited to beef but
can be applied to other resources that may become depleted,
such as tuna and eel. According to Furuhashi, her friend who
saw the news about cultured meat on TV contacted her and said
that she also wants to try cultured meat. Her elementary school
teacher also gave her an encouraging message. She has more
opportunities to feel expectation and attention.
Cultured steak meat could solve global issues, including
meat shortage due to the population increase and
environmental impact due to livestock meat production.
The Group continues to undertake challenges to make cultured
meat a new food option in the near future.
How Cultured Meat
Is Produced by
The NISSIN FOODS Group
STEP1Increasing cells
- 01Increasing bovine muscle cells
-
Allow the enzymes to act on the finely chopped bovine muscle cells to separate the connection between the cells. After this, the cells are cultured for around 1 week until there are about 100 million cells.
STEP2Creating structure
- 01Creating myoblast modules from cultured cells
-
A mixture of cultivated cells and collagen is poured into a mold. The produced sheet-like myoblast modules are aligned to replicate the structure of traditional meat.
- 02Stacking myoblast modules
-
We alternately stack two types of differently-shaped myoblast modules. By continuing to culture the cells in a state where both sides are fixed so there is no shrinkage, the myoblast modules are fused together. A thickness of about 1 centimeter is achieved by stacking around 30 modules.
- 03Discarding the culture solution and culturing cells using a new solution
-
We then cultivate the cultured cells through trial and error to find the optimal conditions for growth.
- 047-day culturing period
-
By continuing cultivation for a 7-day period, the cells inside the tissue grow and become cultured meat in the size of a cube about 1 centimeter in dimension.
