future of protein production with plates with healthy food and protein

Korean researchers at Yonsei University crack the code for flavorful alternative meat

July 15, 2024

The quest for realistic and delicious meat alternatives has reached a new frontier. Researchers at Yonsei University in South Korea have unveiled a novel technique that injects a burst of meaty flavor into these substitutes, potentially revolutionizing the future of our plates.

"Many researchers have been diligently working on developing various bio-scaffolds that can support the growth of 3D structured cultured meat," explains Professor Jinkee Hong, co-author of the study, speaking with BBC Science Focus Magazine. "However, these efforts often overlook a crucial aspect that truly matters to consumers: taste, texture, and overall enjoyment."

Hong highlights the importance of flavor in driving consumer acceptance. While achieving a meaty texture has been a significant focus in the field, capturing the complex symphony of flavors associated with cooked meat has remained elusive.

The Korean team's ingenious solution revolves around a gelatin-based scaffold. Gelatin, a protein derived from animal collagen, provides a biocompatible structure for the meat alternative. But the secret lies within this scaffold.

"We've incorporated a flavor compound into the gelatin," explains Milae Lee, the study's lead author. "This compound is 'switchable,' meaning it remains inactive until exposed to high temperatures during cooking."

This 'switchable' flavor compound mimics the Maillard reaction, a natural chemical process that occurs when meat is cooked. Sugars and amino acids, naturally present in meat, react during the Maillard reaction, producing a cascade of flavor and aroma molecules responsible for the distinctive savory and browned notes we associate with grilled meats.

The researchers cleverly designed their flavor compound to undergo a similar reaction when exposed to high cooking temperatures. As the gelatin scaffold breaks down, these encapsulated flavor molecules are released, creating a burst of meaty aroma and taste within the product.

"Chemical analysis and taste tests conducted with an electronic nose revealed a flavor profile remarkably similar to that of grilled beef," Lee adds.  While the current product's appearance might not fool the eye – resembling a thick pink gelatin – the taste buds tell a different story.

This breakthrough holds immense potential for the future of plant-based alternatives.  "Consumers are increasingly seeking sustainable food options," says Professor Hong. "By offering a more flavorful and potentially more affordable plant-based option, we can encourage a shift towards a more sustainable food system."

The development also opens doors for further innovation. While the current iteration focuses on flavor, further research can explore combining this technology with advancements in texture and appearance, creating a truly indistinguishable plant-based meat experience.
