Microbe-made curdlan fiber helps plant-based meat feel juicier and more realistic
Alternative Protein
The plant-based burger or sausage you cook on the grill gets its juicy bite and fat-like texture partly from microbial fibers like curdlan, which stand in for animal fat and hold water through cooking and freezing.
Curdlan is a gummy fiber that certain bacteria produce when they're short on nitrogen. It forms firm gels, holds water, and survives freezing, so food makers use it to give plant-based meat a realistic chew, mimic animal fat, and control how flavor is released. Researchers are now working on better bacterial strains and fermentation methods to make it cheaply at scale.
Key Findings
Curdlan is a beta-1,3-glucan made by microorganisms under nitrogen-limited conditions, with gelation, freeze-thaw stability, water-holding and thickening properties.
In meat analogues, curdlan improves fidelity and texture through matrix texture modification, animal fat mimicry, and flavor release modulation.
The review covers structure, biosynthesis and regulation, and production advances, and points to strain improvement and fermentation optimization as the next priorities.

Curdlan is a gel-forming fiber made by microbes, and it's becoming a key ingredient for making plant-based meat feel and taste more like the real thing. This review covers how microbes make it and how to produce it more efficiently.

Scientists breed wheat with far less gluten in one generation
If this wheat reaches fields and mills, the bread, pasta, and pastries on your table could someday carry a fraction of the gluten that makes celiac disease s...
Fermentation is an anaerobic metabolic process in which plant cells break down sugars to generate ATP without relying on oxygen, producing byproducts like ethanol, lactate, or organic acids. In plant science, it is essential for understanding how roots and submerged tissues survive low-oxygen
