We run down the history of pasteurization, Louis Pasteur, and why raw milk is more dangerous than you may think. • Don’t miss history! • Follow on INSTAGRAM ► / laughinghistorically • Subscribe to the Podcast ► • Like on FACEBOOK ► / laughinghistorically • --- • TRANSCRIPT: • There is a poison in your household. One that has killed millions of babies and adults throughout history and you probably drink it everyday... • The other day, I posted an instagram I took after randomly stumbling upon the site of the first Milk Pasteurization in the US. Why did I think this was important enough to pull over for? (other than being a real weirdo) • Well, like a lot of human civilization, the story goes back to beer and science. • For much of history, humans didn’t know why beverages became alcoholic.. ie, Yeast eats the sugar and poops out alcohol. In fact, they didn’t really understand micro-biology much at all - their best theories involved Spontaneous Generation - meaning something from nothing. So grapes just magically become wine. There was a whole sect of alchemy devoted to creating Humanuclous, believing that sperm actually had a little man inside of them… another time. • In the mid 1800’s, Napoleon the third (yes there were three), asked biologist Louis Pasteur to figure out why wine and beer went bad so fast. After a lot of “experimentation,” Louis discovers that good beer is full of round yeast cells (which must be what makes fermentation possible) and spoiled beer is full of long harmful bacteria. • He found that to kill the bad invasive bacteria, but not change the flavor of the beer, all he had to do was heat it up rapidly, then quickly cool it off. • This seems pretty obvious today, but this was groundbreaking... civilization changing stuff. • Louis called the process Pasteurization. No one is saying he was that creative with branding, and thankfully he wasn’t a businessman, because he shares his findings with the world. • As you know, the main reason beer was so important, was it was far safer to drink than water or milk. With the spark of industrialization, as more and more humans moved into growing cities, the days between when a cow was milked and when a person drank the product increased dramatically. Without adequate refrigeration, Milk is a perfect breeding ground for all kinds of nasty bacteria, like tuberculosis and scarlet fever - so, it was largely avoided by urbanites, especially the poor. • In the 1890’s, after experimenting on guinea pigs, the milk industry embraced Pasteurization and by the 1910’s it became mandatory by law. This led to a milk boom with more than 750 million tons of milk are produced annually today. • No matter what you read on the internet, pasteurizing milk was a super important discovery. Raw unpasteurized milk is illegal in 18 states and even though it is a fraction of the total milk sold, it accounts for one-third of ALL food borne illness… It is THAT dangerous. • So À votre santé to Louis Pasteur and of course, beer!
