Key Takeaway: A novel curing system that creates concentricly layered scaffolds can be used to produce scaffolds with similar mechanical properties to conventional meat.

Research Topics: scaffold

Summary

Alexis Garrett et al. test the impact of a novel curing system on the structure and efficacy of gelatin-based cultured meat scaffolds. A digital light processing (DLP) printer with a rotational collector plate is adapted to allow the scaffold to be cured radially, yielding concentric layers of scaffold material. Garrett et al. prepare gelatin methacrolyl scaffolds using the DLP printer and perform compression tests on them. These results are compared to compression tests performed on conventional sirloin steak, and it is found the mechanical properties of both the scaffold and the steak are similar. Garrett et al. argue this curing system holds potential in cultured meat production, especially in texture and mouthfeel recreation.
