Food waste. It's the world's dumbest problem. It's also the topic of our most popular podcast ever (see our 2022 interview with Dr. Lisa Johnson). California just passed a new law that dramatically simplifies the 50 potential types of expiration dates currently used on food packaging down to just two. What does Al Capone have to do with all of this? Well, we guess you'll just have to listen to find out.

Soccer, which is known to most to most of the world as football has captured the world's attention during this time of the "Cup That Shall Not Be Named".
My long-time friend, TR Masino (co-host of the Stairway to Eleven music podast) joined me in Mexico City to discuss US vs Mexican food culture, in the context of a "foodball" game. It seemed like a good idea at the time.
Our GOOOOOOALLL!!! is to provide an overview of the similarities, differences, and changes we've seen over the last 25 years of travels between the US and Mexico. In this episode, we "pass" the conversation back and forth and even give a "yellow card" to each side.
See the links below to find out more information on these awesome music and food topics.

We are joined by a guest who is just as comfortable with a pipette as he is with a piping bag. Dr. Josh Smalley is a postdoctoral research associate at the University of Leicester, specializing in the synthesis of peptidomimetic materials. But to millions of viewers worldwide, he is better known as the meticulous finalist from the 2023 series of The Great British Baking Show.
Josh has pioneered a unique niche in science communication, recently launching the 'Science Kitchen'—a project that uses the art of baking to demystify complex chemistry for the public. Today, we’re diving into the 'chemistry of the tent,' how he manages the transition from the lab to the lime-light, and his mission to inspire the next generation of scientists through the universal language of food.
Some of Josh’s favorite books:
The Science of Baking by Matt Alard
The Science of Cooking by Peter Barham
Steeped: The Chemistry of tea by Michelle Francl
'Science of' series by Dorling Kindersley -

Every five years, a massive set of rules, the Dietary Guidelines for Americans (DGA), quietly changes the way 300 million people are "supposed" to eat. But who actually writes these rules? Is it pure science, or is it just the latest dietary trend?
In this episode, we sit down with April Fogelman to go behind the scenes of the federal nutrition recommendations that were recently updated. We’re digging into the evolution of American nutrition, from the nostalgia of the pyramid to today’s "upside-down" recommendations.
Dr. April Fogelman is a Dietician, Lactation Consultant, Associate Professor of Nutrition, and Extension Specialist in our department with interests ranging from infant nutrition to sports nutrition. In addition to her work at NC State, she is an avid marathon runner.

In this episode we've "escaped" our ordinary format to talk with three amazing guests at once:
- Clint Stevenson, NC State Professor and Distance Ed Coordinator
- Dave Seddon, Co-Founder and Chief Safety Officer at FoodReady
- David Wilson, Chief Creative Officer at Intoxicated by Riddles and Co-Founder of the True/False Film Fest
The topic? Clint, Dave, and David's collaborative project using the concept of escape rooms to teach food safety skills. For the beta-test, they let faculty and staff try out the escape room on day one (lot's of fun, I must say), then unleashed students into rooms with three unique scenarios on day two. Can't wait to see what they do with this escape room concept in the future.

Food waste. It’s been called the world’s dumbest problem. Did you know that about a third of the food grown on farms is wasted, meaning it never gets to a factory, a grocery store, or to a consumer? This is not because farmers are wasteful. Far from it. It's because it's sometimes hard to harvest all the food that's been produced, especially if it's underground (think sweet potatoes). Food waste is not just an economic problem, although it can drive up food cost. It is food that is not feeding a hungry world. Dr. Lisa Johnson joins us to discuss her work on food waste and loss. Lisa's research focuses on the critical challenge of food loss at the farm level and how to reduce.

This episode is a recording of our second WDFS Live event. Our guest, Dr. Sarah Ash, Professor Emeritus in Nutrition at NC State University, and Adam Yee, entrepreneur many times over in the food industry, join us to discuss ultra processed foods. What are they? What should you know about them? Some definitions focus on the types or number of ingredients. Few definitions get to the actual process of how foods are made. This interactive presentation and discussion will feature speakers providing their definitions of what ultra processed foods are and talk about the pros, cons, and unknowns surrounding the presence of ultra processed foods in our diets. During the presentation and discussion, we will take questions from the audience. Our goal is a rich discussion that gets to the science behind the health, sustainability, and economic aspects of foods we eat every day.

Adam Yee, a food scientist, entrepreneur, and host of the My Food Job Rocks!, shares his hot takes on startups, alternative proteins, supply chain, and worldwide travel. His recent travels have taken him to Asia where he has done some exploring. He takes some time while in Raleigh, NC to chat with us about podcasting, alternative proteins and the food business considerations when it comes to sustainability. During the podcast, we hear the buzziest of sustainability buzzwords, like "hype-cycle", "greenwashing", and "deep-tech". Our favorite quote from Adam about his work in the sustainable foods arena is "...we have to believe that we are working for a better future".
This is also a great episode if you want to get some practical tips on how to maximize your networking skills in the age of LinkedIn and other social media platforms. Please Note: The audio fades in a few places, but Adam's message comes across loud and clear.

Is preservative a four letter word? We find out what preservative means to a food scientist discussing the balance of food quality with safety through preservation. Is a compound synthesized in a lab inherently bad for our health or do those same compounds occur naturally in our foods? From bacon preserved with celery to 25 year old canned meat, the dose makes the poison.

Have you ever thought about nutrition as a series of tiered services? There’s the basic plan which includes essential nutrients (not everyone gets this basic level, eg. Vitamin D). The basic plan takes into account which nutrients our bodies make and those that they cannot. The premium plan includes those non-essential nutrients. In reality that premium plan is something we are still trying to figure out. And how about an ultra-premium plan? Does that include things like specialist doctors, nutritionists and personal trainers?
Join us as we talk about non-essential nutrients and how they are integrated into our diet and perception of nutrition.

Just in time for Christmas: Fruitcake! When you think of fruitcake, do you think doors stop that will be around for years on end OR a delicious energy packed cake? We walk through many versions of fruit cake and the food science that makes this wonder last so long on our shelves!
Eggnog and its Latin American counterparts, such as rompope and coquito, have been making the season bright for centuries. Versions of the recipe date back at least to the mid-1600s. Recipes usually consist of milk, sugar, egg yolks, spices, and rum, bourbon or other high octane alcohol. Everyone knows what an egg is, but today we answer the question everyone (or maybe no one) has been asking: what's nog?
Gingerbread has a long and storied history. In fact, it may have been the inspiration for the witch's house in Hansel and Gretel. In this episode, we discuss types of gingerbread, a bit of its chemistry, and then get sidetracked with the great molasses flood of 1919. If you are in the area, check out the gingerbread competition going on at the Grove Park Inn in Asheville, NC.

Did you know that a carrot and a glass of milk have about the same amount of water? So why is the texture so different? We jump into how the structures in these foods create incredibly different structures.
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.

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 foods and crinkly packaging. Find out about the iconic structures that form the foods you love.

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 how these siblings are producing such different structures and tastes.

**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!**
**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 preferences?**
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
We all have textural preferences when it comes to our food. Find out the teams preferences for texture in today's episodes. Keith talks about slimy food experiences in Spanish! We get into textural contrast in foods . Followed by how in the world we study structure in foods.
Season 2 is off and running!
Audrey Williams, a student at NC State University, gives us a look at alternative protein sources through the lens of food science. She will explore chemistry, microbiology, engineering and the business aspects of alternative proteins over the next five summer shorts episodes!

In this episode, we finish our two-part discussion of low heat methods and wrap up our first season of Wolfing Down Food Science with an interview with food engineer Dr. Deepti Salvi. While most methods of preservation use significant heat, Dr. Salvi’s work focuses on two methods of food preservation that involve little to no heat, high pressure processing and cold plasma. Tune in to learn the “secrets” behind processing and preserving orange juice, guacamole, lobster, and even raw oysters in ways that make them safe without “cooking”, while preserving nutrients. How do the Northern lights relate to cold plasma? How can cold plasma be used to make fertilizer? What super-cool new preservation techniques are on the horizon. Learn why our new favorite catch phrase is “the three elephants in the room”.

Think about how much space frozen foods take up in a grocery store. How did this all start? On a journey to the arctic, USDA scientist Clarence Birdseye made the observation that fast freezing maintains the quality of food. When he returned to the US, he invented the machinery that resulted in the frozen food industry as we know it today. In this episode we discuss why frozen blueberries are not stuck to one another in a solid block, the importance of fast freezing for ice cream texture, and why just freezing foods cannot make them safe.
3:55 Paige starts talking about Clarence Birdseye.
20:00 Thanksgiving mentioned by Paige
24:40, Paige makes fun of Keith for talking about 50-pound turkeys. :-(
KEY WORDS: IQF (Individually Quick Frozen), blast freezers, ice crystal, glass transition, freeze concentration, sublimation
**In this “steamy” episode, we discuss the ways in which heat is applied in various ways to preserve food. Want to know why organic milk has a longer shelf life than conventional milk? Want to know why canning can actually improve the absorption of some nutrients? Want to know why smoked foods have long shelf lives? What kind of out of the box thinking can we do about microwave ovens?
No matter how it’s done, heating is not just about temperature, but about heating over time. We discuss the pros and cons of lower versus higher heat methods.**
- KEY WORDS: pyrolysis, boiling, various types of pasteurization, canning, sterilization, aseptic processing, smoked foods, microwave processing, continuous processing, heat transfer, conduction, convection, radiation.
- 8:05 Grandfather clock inputs it’s two ticks on High Temperature, High Pressure processing in organic milk
- 17:37 Are you feeling like a 2450 or a 915?
- 19:20 Paige mentions continuous microwave processing, then Keith goes off on a “radar range” tangent. For once, Teresa goes on a tangent at the end.
Ever wonder why some foods are more sour than others or what people mean when they refer to acidity in coffee? Acids preserve foods and add a lot to the flavor of food. From tomatoes to coffee to whey protein beverages we discuss all about acids.
Any off the tracks moments: We get a little off track on Italian cuisine, the origins of tomatoes and noodles! Around 6 min.
