Send us Fan Mail Professor and evolutionary biologist, Chris Vineyard, joins us on the podcast today to talk about the evolution of chewing and how that relates to our texture preferences. We learned about how jaws have evolved and if some of our human tendencies spread to other species as well. Chewing goes back for billions of years and Chris has a look into the timeline.  Got questions or comme...

Send us Fan Mail Texture is iconic.  It's why we love some foods and reject others.  Texture is vitally important to make gluten free and meatless meat products acceptable to the general public.  One of the ways we get to these textures is by forming long fibers or by adding air to make puffy products.  One thing that may get missed is that texture can make foods LOUD. Humans tend love loud f...

Send us Fan Mail The dairy aisle is one big happy family of milk with all kinds of textural variations. Yogurt, cheese, and ice cream are all offspring of a single ingredient: milk! There are great textural transformations that happen when food scientists go through the process of turning milk into these three different food products. This episode, we talk about these wondrous milk derivatives and...

Send us Fan Mail Ever think about how much water could be in any given food? In fact, water concentration can make or break some of our favorite food textures! Food scientists are always interested in how much water is in our foods and how its presence affects textures like gelatin gels and taffy. TRANSCRIPT:  Click here!

Send us Fan Mail We chewed Allen’s brain on his expertise in texture and oral processing in this conversation. Dr. Foegeding’s research includes understanding which food structures create an optimal texture experience and how we perceive that texture when we are breaking down these food structures.  What textures do we like the best? Are companies generating the next wave of food texture preferenc...

Send us Fan Mail It's starting to cool off into fall here in North Carolina and that gets us thinking about campfires and s'mores.  We discuss the ingredients of marshmallows and how those ingredients give us that bouncy texture and delicious stringiness after a campfire treatment Got a questions for us?  Email us at wolfingdownfoodscience@gmail.com Please take a minute to help others fi...
