The demand for protein in America is on the rise, leading to a new focus on precision fermentation as a technology with the potential to scale up production of high-value ingredients. Precision fermentation involves programming microorganisms like yeast to act as mini factories, producing ingredients such as palm oil and proteins. This technology is widely used in the cheese industry to produce rennet, a key ingredient found in young calves’ stomachs.
In recent years, precision fermentation has expanded its capabilities, with startups exploring its use in manufacturing natural food dyes. As ingredient costs rise due to challenges like climate change, precision fermentation offers a promising and environmentally friendly solution to efficiently scale food production.
Cargill, a key player in precision fermentation for over 30 years, has invested over $2 billion in infrastructure and partnerships to support this technology. Florian Schattenmann, Cargill’s chief technology officer and vice president of innovation and R&D, discusses the potential of precision fermentation to revolutionize food innovation.
This conversation has been edited for clarity.
FOOD DIVE: What is precision fermentation and how does it differ from cultivated or lab-grown meat?
Florian Schattenmann: Precision fermentation involves using organisms like bacteria, fungi, or yeast to digest a substrate and produce a target molecule. Unlike cultivated meat, which involves growing cells in a controlled environment, precision fermentation focuses on the cellular digestion process to create specific ingredients like sweetness, proteins, and specialty oils.
Precision fermentation has roots in traditional fermentation processes like brewing beer, but it is more precise and tailored to produce specific molecules efficiently.
What are the benefits of precision fermentation and how will it impact food innovation?
Precision fermentation offers high yield production, minimal water and energy usage, food security, price stability, and control over allergens. By training organisms to produce specific ingredients, this technology can meet the diverse needs of consumers while reducing environmental impact.
How will precision fermentation play a role in companies reformulating to meet consumer demands?
As consumer preferences diversify, precision fermentation can be used to create custom ingredients like sweeteners, proteins, and fats. These ingredients can then be incorporated into a variety of products to cater to different needs and preferences.
Will consumer skepticism towards food technologies like GMOs affect the adoption of precision fermentation?
While consumer skepticism exists, precision fermentation is likely to coexist with other food sources rather than replace them entirely. It will offer additional options for sourcing sweeteners, proteins, and fats, providing consumers with a wider range of choices.
