From Lab to Table: The Science Behind Cultured Meat
Introduction
Photo by Firn
🪶Cultured meat, also known as cell-based meat, is a genuine animal meat product that is created by cultivating animal cells in a controlled lab environment, eliminating the need to farm animals for food almost entirely. The process is borrowed from research into regenerative medicine. Cells are acquired from an animal by harmless biopsy, then placed in a warm, sterile vessel with a solution called a growth medium, containing nutrients including salts, proteins, and carbohydrates. Every 24 hours or so, the cells will have doubled.
✡️The sensory and nutritional profiles of cultured meat are like-for-like with conventional meat because it is made of the same cell types and structure found in animal tissue. The main challenge facing the cultured meat market is producing products at scale. But thanks to the vast amount of research in the stem cell biology space, the science behind cultured foods is not entirely new.
What it is and how it started
🧩The concept of cultured meat was popularized in the early 2000s by Jason Matheny after he co-authored a paper on cultured meat production and created New Harvest, the world's first nonprofit organization dedicated to in-vitro meat research.
Why it matters and what are its implications
🌟Cultured meat has the potential to address the environmental impact of meat production, animal welfare, food security, and human health, in addition to its potential mitigation of climate change. It can also drastically reduce the risks of emerging infectious diseases, which are principally associated with the storage, production, and consumption of animal food.

Difference between plant-based meat substitutes
🏡Plant-based meat is made from various plant-based ingredients, whereas cultured meat is made from animal cells. Plant-based meat is typically cheaper than cultured meat since it is made from readily available plant-based ingredients. In contrast, cultured meat is still in its developmental stages and is more expensive.
✳️Plant-based meat is often considered healthier and more environmentally friendly than traditional meat. In contrast, cultured meat is a potential solution to reducing animal cruelty and environmental impact in the meat industry.
Time to produce cultured meat
🧪The processing time would depend largely on the kind of meat being cultured and other laboratory factors. Although it takes slightly vigorous processes and requires expertise, any kind of cultivated meat should be ready within two to eight weeks.
Is it safe to eat cultured meat?
Cultured meat is high in protein, vitamins, and minerals. It also has the ability to be lower in fat and cholesterol than conventional animal meat. Cultured meat could minimize foodborne illnesses and other diseases transmitted by animals because it’s grown in controlled conditions and without antibiotics. The FDA has ruled that cultivated meat is safe for human consumption.
Taste compared to traditional meat
🧩Cultured meat is believed to have a different taste than traditional meat. Scientists believe that cultured meat has a higher probability of containing amino acids like glycine and alanine which give a sweet sensation than amino acids like leucine and tyrosine which have a bitter aftertaste. Cultured meat tissue from chicken and cattle has significantly lower taste characteristics like umami, bitterness, and sourness when compared with traditional meat.
The flavor of cultured meat can also be influenced by the amino acids and vitamins given to cells in the lab.

The challenges it faces and how it addresses them
❇️Cultured meat faces several challenges in production, such as access to cell sources and cell lines, high raw material cost and animal-source nutrients, limited manufacturing scale and scalability, antibiotics necessity and safety, scaffolding and texture, nutritional quality and assessment, and public acceptance and regulation.
Conclusion
📌Cultured meat is an exciting innovation that has the potential to revolutionize the way we produce and consume meat. While there are still challenges to overcome, the future looks bright for this new form of cellular agriculture.
