Introduction

In this episode of TED Talks Daily, host Elise Hu introduces the topic of collagen, highlighting its prevalence and significance beyond its popular association with skincare. She sets the stage for Fei Luo’s exploration into the ethical and sustainable production of collagen.

Key Points:

• Collagen's Abundance: "Collagen is the most abundant protein in our bodies," Hu states, underscoring its fundamental role in both internal bodily functions and external appearances.
• Purpose of the Talk: Hu emphasizes the need to reconsider traditional collagen sources and introduces Fei Luo's innovative approach to obtaining collagen ethically.

Fei Luo’s Exploration of Collagen

Fei Luo, a collagen chemist, delves into the multifaceted role of collagen in our daily lives and the environmental and ethical issues surrounding its production.

The Ubiquity and Importance of Collagen

Key Insights:

• Dietary Consumption: "An average piece of meat we eat contains anywhere between 0.5 to 3% of collagen," Luo explains, highlighting how intertwined collagen is with our daily diet.
• Industrial Use: Collagen is pivotal in various industries, from food production to health supplements. Luo mentions, "We consume at least a million metric tons of collagen every year through meat."

Notable Quote:

"Collagen is nature's scaffold, holding everything together in a seamless harmony of nutrition and texture." [03:12]

Current Production Methods and Ethical Concerns

Key Points:

• Traditional Extraction: Luo describes the conventional process of extracting collagen by boiling animal carcasses in strong acid to produce gelatin, which is then further processed into collagen hydrolysate.
• Ethical Implications: The reliance on animal carcasses raises significant ethical and environmental concerns, including the impact on animal populations and ecosystems.

Statistics:

• Protein Source: "Any animal's body accounts for 30% of our total proteins," Luo notes, emphasizing the extensive use of animal resources for collagen.

The Need for Sustainable Alternatives

Challenges Identified:

• Lack of Alternatives: Current vegan substitutes for collagen, such as plant-based gummies, often lack the desired texture and consumer appeal.
• Health and Functionality: Collagen's role in health supplements for skin, bones, and overall wellness is unmatched by existing plant-based proteins.

Liven: Pioneering Animal-Free Collagen

Company Overview:

• Foundation and Mission: Three years ago, Luo founded Liven with the mission to produce next-generation collagen without harming animals. Her motivation stemmed from a personal quest for clean, nutritious food for her family.

Innovative Process:

• Genetic Modification of Yeast: Liven genetically engineers yeast to produce collagen similarly to animals. These yeast are then cultivated in bioreactors using sugar or cholesterol as feed.
• Harvesting Collagen: The collagen is extracted from the fermentation broth, ensuring a completely animal-free product.

Notable Quote:

"Using microbes as a manufacturing collagen quickly emerged as our focus because we could see how to brew it easily and it also held numerous health benefits and food functionalities." [05:45]

Overcoming Challenges and Scaling Up

Development Journey:

• Collaborations: Liven collaborates with colleges and universities for formulation testing and validating the quality of their collagen.
• Funding and Growth: The company aims to raise millions of dollars to scale production, ensuring that their solution can meet global collagen demand without increasing livestock farming.

Vision for the Future:

• Transforming Supermarkets: Luo envisions a future where supermarkets feature:
  • "Slaughter-free steaks adorned with perfect marbling," and
  • "Bone broth beacons with their richness and offering velvety texture thanks to the abundance of gelatin."
• Ethical Consumption: Every product in this future marketplace would be sustainable, ethical, and health-conscious, eliminating the need for animal-derived collagen.

Notable Quote:

"Every bite you take is not only delectable and healthy but also sustainable and ethical in its production." [08:30]

Conclusion

Elise Hu wraps up the episode by highlighting the transformative potential of Fei Luo's work in redefining collagen production. She underscores the importance of such innovations in creating a sustainable and ethical future for the food industry.

Final Thoughts:

• Impact on Future Food Systems: Luo's approach could revolutionize how we source essential proteins, reducing environmental impact and animal suffering.
• Broader Implications: The success of animal-free collagen could inspire similar breakthroughs in other areas of food production and beyond.

Closing Statement by Hu:

"If it works, the supermarket in five to 10 years will be completely transformed." [08:50]
