From cosmetics to nutrition, collagen is seemingly everywhere — but we don't often discuss its ethically questionable sources, says chemical engineer Fei Luo. She delves into the groundbreaking technology that uses genetically modified yeast to brew animal-free collagen, a process that could pave the way for a functional, tasty and harm-free future for this crucial protein.For a chance to give your own TED Talk, fill out the Idea Search Application: ted.com/ideasearch.Interested in learning more about upcoming TED events?

Full Episode
You're listening to TED Talks Daily, where we bring you new ideas to spark your curiosity every day. I'm your host, Elise Hu. What do you think when you hear collagen? It is the most abundant protein in our bodies. And even though it's advertised as a key ingredient to youthful looking skin, which is why I always hear about it, we need it far more than just for our outsides.
In her 2024 talk, collagen chemist Fei Luo asks us to reconsider the source of the collagen we all need and offers a more ethical and sustainable way to get it. That's coming up.
Last month, 40 people in Los Angeles tasted a rich and hearty bone broth. It was a special broth, one that involved no slaughter of any animals. The secret ingredient was collagen, brewed like a beer using a special yeast and entire animal free. Do you consume collagen in your daily life? Well, collagen is the most abundant protein in our body.
Any animal's body accounts for 30% of our total proteins. So if you're not a vegetarian, chances are you're already consuming collagen. Or even if you think you don't consume any animal product but not super careful in checking the labels, collagen may still sneak in as capsules in your medicine or fillers in your facial cream. Today, let's talk about food.
Imagine biting into a perfectly marbled steak. That intricate balance of muscle and fat owes its structure to collagen. Collagen is nature's scaffold, holding everything together in a seamless harmony of nutrition and texture. Without it, we'll be left with mere minced fat and muscle. Doesn't seem as appealing, is it?
In fact, an average piece of meat we eat contains anywhere between 0.5 to 3% of collagen. And collectively, we consume at least a million metric tons of collagen every year through meat. Collagen's influence extends far beyond the dinner table. Behind the scene, an entire industry extracts collagen from animal carcasses to produce a myriad of ingredients for food, nutrition and more.
To get all that collagen, animal carcasses are boiled in strong acid to yield gelatin, a magic substance behind the squishiness of gummies that we love and the velvety texture of jello. The industry then further processes gelatin into smaller pieces to make collagen hydrolysis.
millions of health-conscious consumers stir this ingredient in their morning coffees or daily smoothie in order to achieve supple skin, strong bones, or other wellness goals. Because collagen is so versatile in food, a food industry without it is certainly not the same. looking at alternative protein-ingredient products in the market we can buy today.
Meat and seafood amulets are largely in minced form, lacking whole-cut options. Vegan gummies are lacking the squishiness texture in order to attract mainstream snackers. And for millions of consumers, stir collagen powder in their drinks every day. There's no comparable alternatives, so they will be consuming collagen diligently, one that is from the livestock industry.
