A study led by a Finnish research team has discovered a way to produce egg white protein using cellular agriculture, potentially reducing the environmental impact of a widely used ingredient in the food industry. The protein, known as ovalbumin, was produced using the fungus Trichoderma reesei, which was genetically modified to produce the protein. This method has the potential to reduce greenhouse gas emissions, contribute to water scarcity, biodiversity loss, and deforestation associated with chicken egg white production. This development is in line with the growing interest in sustainable alternatives to animal-based proteins in the food industry.
