🎧 Industrial strength craft beer

I’m sure there was audio all the way through the tour, but portions of it were cut out, likely for time editing, but I kind of wish the whole thing was there… I could probably listen to this kind of beer talk all day long. I would also appreciate a more chemistry-based technical approach to the topic as well.

The question of the definition of craft beer versus industrial beer is a very good, yet subtle one.

I’m actually curious to try a beer that’s based on legumes to see what the increased protein percentages do to the flavor. It’s also interesting to hear about the potential creation of a signature Italian style beer.

🎧 A computer learns about ingredients and recipes

Back in February I had retweeted something interesting from physicist and information theorist Michael Nielsen:

I found the article in it so interesting, there was some brief conversation around it and I thought to recommend it to my then new friend Jeremy Cherfas, whose Eat This Podcast I had just recently started to enjoy. Mostly I thought he would find it as interesting as I, though I hardly expected he’d turn it into a podcast episode. Though I’ve been plowing through back episodes in his catalog, fortunately this morning I ran out of downloaded episodes in the car so I started streaming the most recent one to find a lovely surprise: a podcast produced on a tip I made.

While he surely must have been producing the episode for some time before I started supporting the podcast on Patreon last week, I must say that having an episode made from one of my tips is the best backer thank you I’ve ever received from a crowd funded project.

Needless to say, I obviously found the subject fascinating. In part it did remind me of a section of Herve This’ book The Science of the Oven (eventually I’ll get around to posting a review with more thoughts) and some of his prior research which I was apparently reading on Christmas Day this past year. On page 118 of the text This discusses the classic French sauces of Escoffier’s students Louis Saulnier and Theodore Gringoire [1] and that a physical chemical analysis of them shows there to be only twenty-three kinds. He continues on:

A system that I introduced during the European Conference on Colloids and Interfaces in 2002 [2] offers a new classification, based on the physical chemical structure of the sauce. In it, G indicates a gas, E an aqueous solution, H a fat in the liquid state, and S a solid. These “phases” can be dispersed (symbol /), mixed (symbol +), superimposed (symbol θ), included (symbol @). Thus, veal stock is a solution, which is designated E. Bound veal stock, composed of starch granules swelled by the water they have absorbed, dispersed in an aqueous solution, is thus described by the formula (E/S)/E.

This goes on to describe in a bit more detail how the scientist-cook could then create a vector space of all combinations of foods from a physical state perspective. A classification system like this could be expanded and bolted on top of the database created by Jaan Altosaar and improved to provide even more actual realistic recipes of the type discussed in the podcast. The combinatorics of the problem are incredibly large, but my guess is that the constraints on the space of possible solutions is brought down incredibly in actual practice. It’s somewhat like the huge numbers of combinations the A, C, T, and Gs in our DNA that could be imagined, yet only an incredibly much smaller subset of that larger set could be found in a living human being.

Small World

The additional byproduct of catching this episode was that it finally reminded me why I had thought the name Jaan Altosaar was so familiar to me when I read his article. It turns out I know Jaan and some of his previous work. Sometime back in 2014 I had corresponded with him regarding his fantastic science news site Useful Science which was just then starting. While I was digging up the connection I realized that my old friend Sol Golomb had also referenced Jaan to me via Mark Wilde for some papers he suggested I read.

🎧 How much does a nutritious diet cost?

I love that Jeremy raises the question of preparation time in discussing the Supplemental Nutrition Assistance Program (SNAP). It’s something that doesn’t seem most people would consider, but which in the modern world has become a major consideration. To some extent a lot of the growth of obesity in the U.S. is as a result of people going to restaurants and eating less healthy food out, but justifying it for the savings in time and the general convenience.

Some of this discussion reminds me of a talk I saw back in August by Sam Polk, co-founder and CEO of Everytable, a for-profit social enterprise that sells fresh, healthy ready-to-eat meals affordable for all, and founder and Executive Director of Groceryships, a Los Angeles non-profit working at the intersection of poverty and obesity. He was also the author of the book For the Love of Money: A Memoir of Family, Addiction, and a Wall Street Trader’s Journey to Redefine Success.

As I’m listening, I’m curious what these types of programs look like in other countries? How does the U.S. compare? Do those countries leverage the same types of research and come up with similar plans or are they drastically different? I’m thrilled that in the very last line of the episode, Jeremy indicates that he may explore this in the future.

I’ll also guiltily admit that while listening to this episode, I was snacking on M&M chocolate candies while drinking a sugary supplemented beverage. Perhaps I’ll pay my penance later by baking a fresh loaf of bread.

🎧 Food and status | Eat This Podcast

Interesting to think about the shifts of food stuffs between the upper and lower classes over time.

I half expected some discussion of dentition and bone studies, but this was a bit more broadly historical in scope. I always loved the studies of civilizations around 12,000 years ago at the dawn of the agricultural age and the apparently terrible ravaging effects of settling down and living off of of agriculture rather than hunting and gathering.

🎧 Knives: the new bling

Peter Hertzmann Knife skills and knife care are rarely spoken about in many settings and when they are, they’re usually horribly inconsistent, if not butchered. Here Jeremy interviews a real knife guru. Sadly in an audio podcast there’s only so much that can be covered without video. I could have done with another hour on the topic along with some video perhaps.

🎧 Early agriculture in eastern North America | Eat This Podcast

Early agriculture in eastern North America by Jeremy Cherfas from Eat This Podcast
The Fertile Crescent, the Yangtze basin, Meso America, South America: those are the places that spring to mind as birthplaces of agriculture. Evidence is accumulating, however, to strengthen eastern North America’s case for inclusion. Among the sources of evidence, coprolites, or fossil faeces. Fossil human faeces. And among the people gathering the evidence Kris Gremillion, Professor of Anthropology at Ohio State University. She was kind enough to talk to me on the phone, and I made a silly mistake when I recorded it, so please bear with me on the less than stellar quality. I hope the content will see you through. And I’ll try not to let it happen again.

🎧 Sugar and salt: Industrial is best | Eat This Podcast

Sugar and salt: Industrial is best from Eat This Podcast
Henry Hobhouse’s book Seeds of Change: Five Plants That Transformed Mankind (now six, with the addition of cacao) contains the remarkable fact that at the height of the slave trade a single teaspoon of sugar cost six minutes of a man’s life to produce. Reason enough to cheer the abolition of slavery, I suppose. But that doesn’t mean that everything is sweetness and light in the business of sugar. Or salt. A photo gallery in The Big Picture made that very clear, and inspired Rachel Laudan, a food historian, to write in praise of industrial salt and sugar.

We often don’t know how lucky we are to live in the modern highly linked world. The concept of industrialized foods like salt and sugar and their prior histories will certainly bring our situation into high relief. The history here and its broad effects could certainly be fit into the broader category of big history as well.

🎧 What’s the beef with frozen meat?

A stunningly interesting episode.

After listening to this I’m assuredly going to have to look around online for a proper purveyor of frozen beef now. I’ve read several of the studies on the general health benefits of grass fed beef over cornfed, which it terrifically unnatural in the first place.

Frozen meat from the summer slaughter season for the winter months may be just the ticket to a higher quality product. (Though admittedly, they’re right on taking the proper precautions for the freezing/thawing processes as this can make all the difference.)

I find it interesting that the economics of the situation don’t help to better drive this process in the market. While the podcast mentions companies like Whole Foods attempting to educate their customers, I certainly haven’t come across this idea previously, and I typically go out of my way to consume this type of information.

The tough part of the process is determining when the product was frozen, as I’m sure many processors may just as readily freeze their excess winter slaughter. I checked in a local high end grocery store today and found a few types of frozen grass fed beef, including one from New Zealand, but the packaging didn’t indicate when it was frozen or even by whom in the process. There was only an obscure future date which I could only take to be either a “sell by” or “consume by” date as it wasn’t otherwise marked. If purveyors want to improve their position in the market, providing this type of data would be helpful, though I suspect it’s more in their interest not to indicate anything at all unless bulk purchasers and distributors like Whole Foods pressure them to do so. Perhaps the majority of the demand in the market (and specialty pricing) stops at the words “grass fed”?

🎧 This Week in Google 392: Buried in the Common Area

The story about DeepMind learning to be aggressive as it gets smarter is quite interesting and could provide an interesting model of larger interconnected societies. Smaller groups require more civility while larger may not. The question is how to interconnect groups to help cut down on the aggressiveness. Perhaps some of the network ideas in the toy mathematical models from Stuart Kauffman could be useful here? This could be a very interesting problem to work on.
