Advancements in biotechnology and gene editing tools like CRISPR are changing the agriculture industry for the better. While CRISPR is being used to produce better crops and sustainable beef, lab cultured meat is another promising alternative.

What does cultured meat mean? Does it taste the same? How is it different from regular meat? We’ll provide you with answers to all of these questions and more. Here’s an overview of what we’ll cover:

What is Lab-Grown Meat?

Lab-grown meat, or cultured meat, is produced through the cultivation of animal cells in vitro. Since lab-grown meats are grown from cells, it’s a solution to the ethical issues surrounding livestock agriculture. Cultured meat is produced in a controlled environment, free from bacteria and diseases.

Despite being grown in a lab, lab-grown meat is close to “real” meat, as it is made from animal cells. Although cultured meats are not yet commercially available, research in ongoing on making these marketable in the next few years.

The History of Cultured Meat

Who came up with the idea of cultured meat, and how did it become something that might be hitting grocery store shelves soon? Through years of research and trials, and countless hours of work by numerous scientists, lab-grown meats were created.

Here is a timeline of how and when genetically made meat came about:

Year
Event
1998
Jon Vein secures a patent for the production of lab-grown meat tissue for the purpose of human consumption.
2002
The first edible lab-grown meat sample is produced: a fish fillet made from cultured goldfish cells.
2013 The first lab-grown beef hamburger was consumed at a press event. The burger was created by Dr. Mark Post at Maastricht University in the Netherlands, and the event was hosted in London, England.
2018 Dutch startup company Meatable claims they will be able to produce cultured meat from stem cells sourced from animal umbilical cords, solving the problem of needing to kill an animal initially to get starter cells for production.

How is Lab Meat Made?

Lab grown meat is made by the controlled culture of animal cells. Scientists commonly grow cells in the lab, and this process is not too different. While the specifics behind how lab meat is grown in companies is proprietary, the basics behind it consists of keeping cells happy in a culture environment to promote their survival and continued growth.

Lab grown meat starts with animal cells, typically muscle or fat cells, or stem cells that are forced to differentiate into muscle cells. These cells are cultured using the appropriate growth medium that contains nutrients that promote its growth and survival. To aid in the growth of culture as it begins to expand, edible scaffolding is sometimes used. Finally, cells are allowed to divide and expand until ready to use, all the while being monitored consistently for harmful bacterial contamination.

Challenges of Working with Lab Cultured Meat

In addition to the societal stigma that lab made meat faces, there are other challenges that come along with creating meat products that resemble traditionally-sourced meats, including replicating texture, appearance, and taste. Here are some of the main difficulties:

1. Speed and density of cell growth

This is a challenge because while individual cells can grow quickly, it can take some time for a larger tissue segment to form. In addition, if the cells aren’t forming together at the same density as traditionally sourced meat, the texture of the product won’t come out the same way.

2. Growth medium requirements

Cells require proper growth medium rich in nutrients in order to survive and grow. Since lab grown meat is ultimately meant for human consumption, the high quality growth medium free of common allergens are necessary.

3. Lack of blood vessels

Blood vessels normally deliver blood to tissue to survive. In lab-grown tissues, blood vessels are not present, so scientists must think of new ways to deliver nutrients, taking the place of naturally occurring blood vessels.

4. Cost to produce

Lab-grown meats are still only being produced on a fairly small scale, and though the cost to make them has drastically decreased from the $330,000+ it used to cost, lab meat is very expensive to produce at around $2400/pound of lab beef, according to Memphis Meats. If adopted by larger companies and produced on a large scale, the cost will be reduced significantly.

5. Replicating the taste of traditional meat

To motivate meat lovers to switch to lab-grown meat, the taste needs to be the same or very close to that of traditional meat. Many people would be quite put off if the taste leaves too much to be desired. More work is needed to ensure that the taste of cultured meat will please the foodies of the world.

5 Companies Producing Lab Cultured Meats

There are now several companies working on bringing lab-grown meat and seafood products to consumer markets worldwide. Here’s a rundown of five awesome companies creating these products:

Memphis Meats had the idea for cell-based meats and poultry products in 2005, and in 2015, they finally launched and began producing the meats. They created the world’s first cell-based meatball in 2016, with poultry following shortly after in 2017.

Under the vision and execution of CEO & founder Dr. Uma Valeti, Memphis Meats hopes to scale in such a way that less land, water, energy, and food inputs are consumed by the meat industry, and quality, healthy, and safe cell-based meats can reach grocery stores in coming years.

As their slogan states, Finless Foods offers you “sustainable seafood, without the catch.” They are bringing sustainable, cell-based seafood products to your table, starting with bluefin tuna. This achievement would help solve the environmental problem that commercial fishing is causing, and would improve the nutritional quality of the fish being consumed.

Meatable is creating hamburgers from single animal cells, in a much faster, cleaner, and more sustainable way than traditional livestock-sourced burgers. Their process claims to produce a hamburger in 3 weeks or less, which, when compared to the minimum 3 years traditional meat takes, is a significant improvement. You can check out their product creation cycle to learn more about the timeline of this process.

SuperMeat got started through a crowdfunding campaign on Indiegogo. They’re working to create animal-friendly meat products in partnership with PHW-Gruppe, one of Europe’s largest poultry producers.

Like all the other companies here, their product will help solve the environmental impact issues of the meat industry, but SuperMeat’s marketing and branding also focuses on the humanity of how this type of meat production will prevent the slaughter of animals.

Mosa Meat was the groundbreaking company responsible for the first lab-grown hamburger showcased in 2013. Since then, they’ve been hard at work to get their products ready for commercial production, and are aiming to make them available to consumers within the next few years.

Their main goal is to bring cultured meat (or “clean meat” as they call it) to the mass market to help satisfy the growing demand for meat, which they believe will hit a critical stage by 2050. They also claim that while the process is very expensive now, over time, they will be able to reduce the price to about the same as a typical beef hamburger in the supermarket.

How is Lab Meat Different from Plant-Based Meats?

A new wave of meatless meats are becoming more popular since coming to the market in the last few years, however it is important to distinguish that those are not the same as cultured meat. The meatless meats you might be familiar with are plant-based ‘meats’ and contain no animal tissue whatsoever, though can sometimes contain animal byproducts like eggs.

The ingredients listed in a lab meat hamburger would be “ground beef” while common ingredients in a plant-based burger made famous by companies like Impossible Foods or Beyond Meat include soy, beans, tofu, vegetables, grains, mushrooms, and other non-meat products.

Cultured meat is not synonymous with vegetarian or vegan-safe foods, as it contains animal cells. While lab cultured meats are not vegetarian, they provide a more friendly alternative for those who choose to refrain from eating meat because of animal cruelty or environmental reasons.

How is Lab Grown Meat Different from Conventional Meat?

If lab produced meats are similar in appearance, texture, and taste to conventional meat, how are they different? Are the products the same? Is there a reason to choose one over the other?

Here are the ways cultured meat differs from traditionally-sourced meat:

Artificiality Grown from animal cells in vitro i.e. in controlled lab conditions
Comes directly from animals that have been sacrificed for consumption
Impact on environment More environmentally friendly due to lack of greenhouse gas production
High environmental impact with land occupancy and greenhouse gas emissions
Ethics A more ethical alternative as animal cells are used Killing animals for consumption raises ethical issues
Health Harmful additives are minimized in lab grown meats May contain additives like growth hormones, antibiotics, and other chemicals
Cost to produce Due to its process, lab grown meat is currently very expensive to produce Traditional meat is fairly affordable for an average person to buy
