Episode 8: Yes, Chocolate is a Material

how you process it makes all the difference

We all think of metals, ceramics, polymers, electronic materials, composites and so forth as materials. But what else? Is chocolate an engineering material? In this episode we dive into this amazing substance and describe the critical processing steps that makes it a unique including regional differences in cocoa, chocolate tempering and more. Along the way we'll cover the fundamental materials science topic of crystallization and solidification.

If you want to learn more about the science of chocolate there is a huge body of literature. Some publications you can check out are Beckett's Industrial Chocolate Manufacture and Use, Fifth Edition https://onlinelibrary.wiley.com/doi/book/10.1002/9781118923597 which is essentially the industry standard in this field. There are also some great review articles like “Fat bloom in chocolate and compound coatings” by Lonchampt and Hartel https://dx.doi.org/10.1002/ejlt.200400938. There's also the excellent book Stuff Matters by Mark Miodownik. Finally, Harvard University has an excellent YouTube series on the science of cooking including a great episode on chocolate that is worth checking out https://youtu.be/HS263kcm8Jc.
