Would you eat lab-grown meat?

When a research team from the Netherlands presented the world's first burger grown from cultured animal cells, they set off the next huge race in science and the food industry.

And while the idea of growing meat in a petri dish was mind-boggling at the time, so too was the production cost of about $400,000.

The next challenge: how to make it commercially viable to produce?

Fast forward almost 10 years and many millions of dollars later, the emerging cellular agriculture industry is pushing to meet growing demands on the global food systems – largely driven by demographics.

Food and health expert Professor Johannes le Coutre, from UNSW School of Chemical Engineering, says that foods produced from cell cultures will have the same nutritional value as those produced from vegetables and animals.

"Cellular agriculture is a growing field of activities that are deeply rooted in existing technology to produce food. It combines elements of agriculture, life science, medical research, and engineering with the goal of growing edible tissues from vegetables or meat at the cellular level.

"The technology enables us to provide real meat – without having to kill an animal."

The process involves taking cells through a small biopsy from a live animal. The material is then subjected to a number of biological steps to ensure it has the same nutritional features, look, texture and most importantly, flavour characteristics as real meat.

"The meat we consume is only a fraction of the animal. With the developing technologies in tissue culture and organ engineering, it's slowly becoming possible to grow these materials in the laboratory."

Animal free solutions
Professor le Coutre says consumers will be more likely to accept the idea of eating meat that's produced in ways similar to cheese and yoghurt if there is a clear added benefit. And one of the biggest advantages of recreating meat, is knowing exactly what's in it.

"It is about a new wave of domestication," he says.

"Growing the meat is just one part of it. At UNSW, we're asking additional important questions about the mechanisms that are important to grow and scale this industry.

"We are advancing the food safety and nutritional aspects around it too, and then of course, using science to scale it underpins everything we do."

It's a problem for the planet too
Cellular agriculture foods directly address other pressing issues, such as climate change. The costs of meat products in the market do not recuperate the full environmental costs involved with their production such as greenhouse gas and water use.

Professor le Coutre says that animal farming accounts for about 14 per cent of greenhouse gas emissions, and the livestock industry is among the largest drivers of biodiversity loss. In some countries, an estimated 25 per cent of the freshwater supply is used for livestock production.

"The livestock industry and the connected food systems are running into various issues including credibility and sustainability."

"This sustainability argument is relevant because you can put clear numbers on it. The data tells us that agriculture and the systems driving livestock growth are leading to greenhouse gas emissions much higher than those generated by the aviation industry."

"What we're working on is not only scientifically and commercially exciting but ethically exciting too because it's going to change our relationship with food."

But what about plant-based meat alternatives?
The reality of having a burger made from vegetables is not a new idea. Take a walk down the freezer aisle of your local supermarket and you can find sausages or chicken schnitzels made entirely from plant material.

"Don't confuse the two," says Prof. le Coutre. "Real meat cells are smaller and more nutrient dense compared to plant cells, which contain a lot of water.

"If you take plant-based tissues and try to turn them into food that has the same appearance as meat, you inevitably conduct processing steps detrimental to the original plant material.

"People should eat vegetables and plant materials such as beans, peas, legumes – that's wonderful and great. However, I continue to believe we should consume meat products in moderation. And with the future of cellular agriculture, we can do this in a sustainable way."

Beyond meat
Prof. le Coutre says the future of cellular agriculture is not confined just to cultured meat, but to sustainably produce materials for other industries such as seafood or even dairy. While proofs of principle have been obtained, further research is needed to ensure lab-produced meat satisfies consumer expectations and can be manufactured at a reasonable cost.

"The ambition is to get the cost down to below that of traditional meat to make it acceptable for the consumer but we are not there yet. Our goal is to commercialise what we're achieving through R&D and to see products dominate supermarket shelves within the coming 5-10 years."

Prof. le Coutre says the research they are working on is multidisciplinary with the intention to redefine the entire value chain for a novel food system. More investment is needed to reach the full potential in this field.

"We need to position Australia as a leader in this space. We are already paving the way in the food agriculture business, but we need to be ahead in the cellular agriculture business as well."

Would you eat meat that was grown from animal cells?


Sounds better to me than plant based  alternatives especially with the same flavour characteristics

If the world population keeps increasing something like that will have to be done.

At age 92, I doubt if it will be commercially available in my lifetime, however, yes I would eat it if, it was within my budget which decent tender beef or lamb is not at present prices.

I'm not interested in eating any type of meat but for the exploding world population it has to be the solution

I don't feel the need to eat meat of any kind, but I see cell-based meat as a necessity for the meat-eating ever-growing human population, on a planet of finite resources, already in advanced environmental stress and degradation.

Obviously, for animals, it's a far more humane alternative to the horrors of industrialized farming and slaughterhouses. 

If dairy and eggs could also be cell-based, that would be excellent too. Industries that treat animals like production machines and dispose mercilessly of their male babies (the unwanted 'waste'of dairy and egg industries) need to be superceded, from a compassionate and ethical point of view.

I hope this rolls out really fast now, and note that in some countries, cell-based meat production already has government backing (such as Singapore, where a cell-based chicken company has received govt funding). 

I am not a meat eater but NO I would never eat lab-grown stuff

I think I would take the plant based alternatives instead which can actually be okay, lab-grown stuff doesn't sound good! Does anyone have any recommendations on the plant based alternatives?

I would not eat any meat grown in a lab. I would however eat vegetables grown in a lab.

In today's age, several printer brands produce various printers from low to heavy. As a result, among the different printer brands, Canon is one of them. Canon printers are among the most well-known and widely used printers. They still have a reputation for producing high-quality printing papers. However, in order to use a Canon printer, you must first set it up from the official website, i.e., “ij.start.cannon.” Furthermore, Canon produces printers for both home and office use. Canon printers are a decent choice if you want a sturdy and dependable printing unit.





This technology is used all the time in "Startrek" and science fiction movies

Science is just catching up.

I like vegetables BUT will I never eat plant based burgers or lab meat, only real meat for me and eggs, cheese, butter and full fat dairy.  Some nutrients are only found in natural animal foods such as red meat, eggs etc. As we get older getting enough protein, iron, B12,  fat soluble vitamins A, D and K2 is very important. As we get older we need more meat, not less.
