Can Cultivated Meat Satisfy Global Protein Demand?
by Jay Dhadhal
In recent years, a revolutionary concept has emerged in the world of food production: lab-grown meat. Also known as cultured meat, in-vitro meat, or cell-based meat, this innovative technology promises to transform the way we produce and consume protein. But can it truly satisfy the world's growing demand for meat? Let's dive deep into this fascinating topic.
The Global Protein Challenge
To understand the potential impact of lab-grown meat, we must first grasp the scale of the global protein demand. Global per capita meat consumption varies significantly by region, reflecting differences in dietary preferences, economic conditions, and cultural practices.
These factors create a pressing need for alternative protein sources that can meet nutritional needs while reducing environmental impact.
What is Lab-Grown Meat?
Lab-grown meat is real animal meat produced by cultivating animal cells in a controlled laboratory environment. Unlike traditional livestock farming, it doesn't require raising and slaughtering animals.
The science behind cultivated meat involves several key scientific processes mentioned below:
Cell Selection and Banking: The process begins with acquiring and banking stem cells from an animal. These cells are then grown in bioreactors at high densities and volumes.
Cell Culture and Differentiation: The cells are fed an oxygen-rich cell culture medium made up of basic nutrients such as amino acids, glucose, vitamins, and inorganic salts, and supplemented with growth factors and other proteins. Changes in the medium composition, often in tandem with cues from a scaffolding structure, trigger immature cells to differentiate into the skeletal muscle, fat, and connective tissues that make up meat.
Harvesting and Processing: The differentiated cells are then harvested, prepared, and packaged into final products. This process is expected to take between 2-8 weeks, depending on what kind of meat is being cultivated.
Scaffolding and Tissue Engineering: To create the desired texture and structure, scaffolding techniques are used to arrange the cells into a specific pattern. This can be done using edible materials that support the organization of meat cells into the desired shape.
The result is a product that is biologically identical to conventional meat but produced without the need for animal agriculture.
Advantages of Lab-Grown Meat
Lab-grown meat offers several potential benefits:
Environmental Impact: It could significantly reduce land use, water consumption, and greenhouse gas emissions associated with traditional animal farming.
Animal Welfare: The process eliminates the need for large-scale animal rearing and slaughter.
Food Safety: Produced in controlled environments, lab-grown meat could reduce the risk of foodborne illnesses and the use of antibiotics in meat production.
Customization: Scientists could potentially enhance the nutritional profile of lab-grown meat, adding vitamins or adjusting fat content.
Land Use: Freeing up land currently used for livestock could allow for reforestation or other uses.

Challenges and Limitations
Despite its promise, lab-grown meat faces several hurdles:
Scale: Scaling up production to meet global demand remains a significant challenge.
Energy Use: The energy required for large-scale cell cultivation could be substantial.
Consumer Acceptance: Many people may be hesitant to embrace meat grown in a lab.
Regulatory Approval: Ensuring safety and gaining regulatory approval in various countries is a complex process.
Nutritional Equivalence: Ensuring lab-grown meat matches or exceeds the nutritional profile of conventional meat is crucial.
The Road Ahead
The cost of cultivated chicken has decreased significantly over the years. In 2013, the first lab-grown burger was produced at a cost of $325,000. By 2016, the cost of cultivated beef had decreased to $40,000 per kg, and cultivated poultry cost $20,000 per kg.
In 2017, Finless Foods produced cell-cultured seafood at a cost of $19,000 per pound, which decreased by 50% to $9,500 per pound by the end of the year. By 2019, Shiok Meats had produced cultivated shrimp dumplings at a cost of $5,000 for 8 dumplings.
In 2020, SuperMeat opened a test kitchen in Tel Aviv to premier its cultured chicken burgers, and Eat Just became the first company to get regulatory approval for cultivated meat in Singapore.
In the year of 2021, the cost of cultivated chicken breast had decreased to $7.50 per quarter pound serving, or $66 per kg, by Future Meat Technologies. The chart below gives a good idea on the trend.
While lab-grown meat shows promise, it's unlikely to completely replace conventional meat in the near future. Instead, it's more likely to become part of a diverse protein landscape that includes:
As technology advances and production scales up, lab-grown meat could play an increasingly important role in meeting global protein demand, especially in urban areas or regions with limited agricultural resources.
Conclusion
Lab-grown meat has the potential to significantly contribute to satisfying global protein demand, offering a more sustainable and ethical alternative to traditional meat production. However, it's not a silver bullet.
Addressing the world's protein needs will likely require a combination of approaches, including improved agricultural practices, alternative protein sources, and changes in dietary habits.
As research progresses and technology improves, lab-grown meat may become an increasingly viable option. Its success will depend on overcoming current limitations, gaining consumer acceptance, and integrating into existing food systems.
While it may not completely solve the global protein challenge on its own, lab-grown meat represents an exciting step towards a more sustainable and secure food future.
