Precision fermentation is emerging as a promising technology that could play an important role in the future of food production. Scientists are using specially engineered microorganisms to create food ingredients that closely resemble traditional products while reducing resource use and environmental impact.
The technology is already being used to develop products such as alternative proteins, egg white substitutes, vitamins, nutrients, and food colorants. Some of these ingredients can mimic the appearance, taste, and texture of conventional foods. Researchers believe precision fermentation may help strengthen global food systems and support food security in the years ahead.
Unlike traditional fermentation, which relies on naturally occurring microorganisms to produce products such as cheese, bread, and beverages, precision fermentation uses genetically engineered microorganisms. These microorganisms are designed to produce specific ingredients by redirecting cellular processes. One example is leghemoglobin, a protein that gives plant-based burgers a meat-like red color.
The University of Illinois Urbana-Champaign is actively advancing research in this field through facilities such as the NSF iBioFoundry and the Integrated Bioprocessing Research Laboratory (IBRL). These facilities help researchers and companies move new technologies from research stages toward commercial production.
“Precision fermentation is one of our core competencies, and one of the areas that has been the busiest for the IBRL. Currently, we're seeing a lot of interest from the major consumer packaged goods companies on replacing traditionally petroleum-derived ingredients with natural alternatives, including food dyes, non-caloric sweeteners, and preservatives,” said Beth Conerty, IBRL Associate Director of Business Development.
The university has also partnered internationally through the Centre for Precision Fermentation and Sustainability (PreFerS) in Singapore. The research center focuses on developing microbial technologies that can produce alternative proteins, vitamins, and other nutrients more efficiently.
“Singapore is a small country with no agriculture, so they are very interested in using precision fermentation for food production,” he said. “The center focuses on advancing technologies for microbial cell engineering to produce targeted nutritional molecules, including alternative proteins and vitamins. The goal is to enhance cost-effective production of safe and nutritious foods, ultimately improving food security while reducing environmental impacts.”
Researchers classify precision fermentation products into different categories, including high-value ingredients, functional ingredients, and commodity ingredients. Examples include beta-carotene food colorants, ovalbumin protein used in baking, amino acids for animal feed, and single-cell proteins for food applications.
“Most products are currently developed in the high-value category, which is a small market. My vision is to fill the whole pyramid, including commodity ingredients, within the next 10 to 20 years to obtain greater environmental impact,” Jin said.
Researchers also emphasize the importance of consumer acceptance and economic feasibility when developing new products.
“Scientists typically study fundamental technology, while consumers in the marketplace are looking for mature products,” Jin said. “But if we start with consumer input, we can ensure greater acceptance. We also need to conduct techno-economic analysis to evaluate market viability. This is a paradigm shift that is needed to advance the precision fermentation industry,” he said.
As research continues, precision fermentation is expected to become an increasingly important platform for sustainable food production, helping create nutritious, affordable, and environmentally responsible food ingredients for future generations.
