The Impossible Burger, a plant-based patty that mimics the taste, texture, and aroma of meat, has taken the culinary world by storm. One of the key factors contributing to its meat-like characteristics is the presence of heme, a molecule that gives the burger its distinctive flavor and color. But have you ever wondered what the source of heme in the Impossible Burger is? In this article, we will delve into the science behind the Impossible Burger’s heme and explore the innovative technology that makes it possible.
Introduction to Heme
Heme is a complex molecule that plays a crucial role in many biological processes. It is a key component of hemoglobin, the protein in red blood cells that carries oxygen throughout the body. Heme is also found in other proteins, such as myoglobin, which stores oxygen in muscles. In the context of the Impossible Burger, heme is responsible for the patty’s meat-like flavor, texture, and aroma. But how do the manufacturers of the Impossible Burger source this essential molecule?
The Traditional Source of Heme
Traditionally, heme is found in animal products, such as meat, fish, and poultry. The heme in these products comes from the animals’ hemoglobin and myoglobin. However, the Impossible Burger is a plant-based product, which means that it cannot rely on animal sources for its heme. So, where do the manufacturers turn to for this essential molecule?
Plant-Based Heme Sources
The answer lies in a type of yeast called Pichia pastoris. This yeast is a microorganism that can be genetically engineered to produce a variety of proteins, including heme. The manufacturers of the Impossible Burger use a proprietary technique to engineer the yeast to produce a plant-based heme molecule that is identical to the heme found in animal products. This plant-based heme is then used to create the distinctive flavor and color of the Impossible Burger.
The Science Behind Plant-Based Heme
So, how does the yeast Pichia pastoris produce heme? The process involves a complex series of genetic engineering and fermentation steps. First, the yeast is genetically engineered to produce the enzyme leghemoglobin, which is a plant-based protein that is similar to hemoglobin. The yeast is then fermented in a controlled environment, where it produces the leghemoglobin protein. The leghemoglobin is then purified and used to create the heme molecule.
Benefits of Plant-Based Heme
The use of plant-based heme in the Impossible Burger has several benefits. For one, it allows the product to be vegan-friendly, making it accessible to a wider range of consumers. Additionally, the use of plant-based heme reduces the environmental impact of the product, as it eliminates the need for animal agriculture. Animal agriculture is a significant contributor to greenhouse gas emissions, deforestation, and water pollution, so the use of plant-based heme is a more sustainable option.
Comparison to Animal-Based Heme
But how does plant-based heme compare to animal-based heme? In terms of nutritional content, the two are similar. Both plant-based and animal-based heme are rich in iron, which is an essential nutrient for human health. However, the production process for plant-based heme is significantly more efficient and sustainable than the production process for animal-based heme. The use of yeast fermentation to produce heme reduces the land, water, and energy required to produce the molecule, making it a more environmentally friendly option.
Conclusion
In conclusion, the source of heme in the Impossible Burger is a type of yeast called Pichia pastoris. This yeast is genetically engineered to produce a plant-based heme molecule that is identical to the heme found in animal products. The use of plant-based heme in the Impossible Burger has several benefits, including reducing the environmental impact of the product and making it accessible to a wider range of consumers. As the demand for plant-based products continues to grow, the technology behind plant-based heme is likely to play an increasingly important role in the development of sustainable and innovative food products.
Future Implications
The development of plant-based heme has significant implications for the future of food production. As consumers become increasingly aware of the environmental and health impacts of their food choices, the demand for plant-based products is likely to continue to grow. The use of yeast fermentation to produce heme and other molecules could revolutionize the way we produce food, making it more sustainable, efficient, and environmentally friendly. Additionally, the technology behind plant-based heme could be used to develop new products and ingredients, such as plant-based eggs, dairy, and meat alternatives.
Final Thoughts
In final thoughts, the source of heme in the Impossible Burger is a testament to the power of innovation and technology in the food industry. The use of plant-based heme in the Impossible Burger has opened up new possibilities for the development of sustainable and vegan-friendly food products. As we look to the future, it will be exciting to see how this technology continues to evolve and impact the way we produce and consume food.

What is heme and why is it important in the Impossible Burger?
Heme is a molecule that is naturally found in plants and animals, and it is a key component of hemoglobin, myoglobin, and other proteins. In the context of the Impossible Burger, heme is used to give the patty its characteristic red color and meaty flavor. The company behind the Impossible Burger, Impossible Foods, uses a genetically engineered yeast strain that produces a molecule called soy leghemoglobin, which is a type of heme. This molecule is what sets the Impossible Burger apart from other plant-based burgers and gives it a more realistic taste and texture.
The use of heme in the Impossible Burger is also significant because it allows the patty to “bleed” like a traditional beef burger. When the patty is cooked, the heme molecule is released, creating a reddish-pink liquid that resembles blood. This effect is not only visually striking, but it also enhances the overall culinary experience of eating the Impossible Burger. Furthermore, the heme molecule is also responsible for the patty’s rich, meaty flavor, which is a key factor in the Impossible Burger’s popularity among consumers. Overall, the use of heme in the Impossible Burger is a crucial aspect of its innovative design and a major contributor to its success.
How is the heme molecule produced for use in the Impossible Burger?
The heme molecule used in the Impossible Burger is produced through a process of genetic engineering and fermentation.
