Mass-Producing Ice Cream with Food Engineering: Crash Course Engineering #39

[@crashcourse]

@ 4:41 we incorrectly used an image of Neil Borlaug from a previous episode instead of Louis Pasteur! Sorry about the mixup and thanks to the smart commenters who caught the error! For an *actual* picture of Louis Pasteur: en.wikipedia.org/wiki/Louis_Pasteur

[@bewtful-sunrise]

It's okay, you guys are already too smart for me to keep up(in a good way)

[@Saltpork305]

The man at 4:42 isn't Pasteur, it's Norman Borlaug. Mr. Borlaug was the man given the Nobel peace prize in 1970 for saving a billion humans from starvation due to his work with high yield genetically modified grains.

[@markholm7050]

Saltpork305 That definitely needs to be fixed.

[@cliftonb]

Ha, I was just thinking Louis looks an awful lot like Norman. I think the last episode had a bit on Borlaug, so they must have messed up the assets.

[@crashcourse]

YIKES. You are correct! Sorry about that!

[@TheBreezus]

Yeah I just seen that right after watching the video for genetic engineering. It's just a small oops, but both folks did great work for our species

[@Nosseb2]

@@crashcourse Shouldn't you put up an eratum ? You know you can display cards or infos in the videos with KZbin Tools without re-uploading the video. I don't think it would take long and it's a great short term solution. You're a science channel right ?

[@Bosgek0]

As a food engineer I really liked how you've condensed down a very wide field. You've touched on the physics, chemistry, microbiology parts and noted the importance of food safety and taste. Other important subject are keeping prices low and making consistent products from raw materials whoes properties can vary a lot. Overall a really good job. I'll share it with colleagues.

[@zhubajie6940]

One of the worst parts of food engineering is that many foods as liquids have complex fluid mechanics. Unlike say water, many are non-homogenous mixtures, colloids, and have non-newtonian shear natures. The perfect example is ketchup. "Shake, shake the ketchup bottle / First none'll come, and then a lot'll" So keeping things flowing at the right speeds can get complicated.

[@cateevered5661]

Is ketchup a type of Bingham fluid or shear thinning?

[@Dustman3400]

At 3:32 you state everything needs to be “sterile”. That’s not an accurate statement. The food industry sanitizes, which means they reduce the amount of micro organisms to a significantly lower level. Sterilize means to remove all micro organisms, which isn’t practical or necessary for a safe food process.

[@emr1248]

Well by sterility, i think she meant the term "commercial sterility" which means that it is free from pathogens and safe to use but can still have spoilage organisms still present. It is essentially the same thing as the sanitization that you mentioned, but i feel like she probably did not think to emphasise that it is not true biological sterility.

[@charlescui221]

Since I'm assuming Crash Course is made for a global audience, I think it would be helpful to specify which degree unit (C or F) the lecture uses.

[@nafrost2787]

If you ask me, best thing to do, is to use Celsius, but write Fahrenheit value on the side.

[@knowsy_parker]

Her accent, her diction, and her intonation make this process of learning even more perfect.

Dajana Osmani Nothing like a Brown girl with an English accent.

[@OMB-hq6lm]

And nice to look at

[@DogsBAwesome]

I wonder how many millions of lives has pasteurization saved? science FTW.

[@DarknessBlossoms]

I love Crash Course.

[@emilysytpage]

Love this host and series. This course is in my Top 5

[@FalbertForester]

Good work on all the callbacks to other engineering topics already discussed in the series.

[@RyanWeaver-fp5kq]

Natural and gut health… and saving food… absorption and design thinking engineering of optimism’s.

[@stefaniecoronel1226]

Finally my engineering!!

[@middlegrounds109]

Absolutely fascinating video. Love your hair by the way.

[@charles4112]

I almost didn't realize the pizza John reference.

[@shawnlandden2310]

Cream is lighter than milk, and would thus go to the center of the centrifuge (or the top when settled, as is the traditional way, and why homegenization is used). I think you got that fact wrong.

[@TheRWS96]

I am wondering whether the book on the shelf besides the lamp is deforming due to the lamp. (It was less misformed at the first episode)

[@mileyli1347]

I am in my last year of food engineering. 🤣

[@Mmmmk9797]

Hi! I'm thinking of majoring in food engineering. Any advice??What did you like the most about it and was the most difficult part?

[@mileyli1347]

@@Mmmmk9797 Hi, first I am studying in Panama, in the The Technological University of Panama. So in other countries may be different. For me the difficult thing was to adjust to a new environment, but then I got use to it. But for the given subjects, I felt like Heat transfer, Electrical systems, mass transfer were kind of difficult but not impossible. Now I'm on last year I'm seeing more of subjects related to food such as Fruits, Meats, etc.. I can advise you to enjoy your university time as much as you can and for your graduation I recommend you to make a thesis if you plan to make post graduate studies.

[@Mmmmk9797]

Miley Li Thank you for sharing your experiences. It’s very motivating for me(:

[@meowth900]

More food science videos plz

[@AnaleenAelwyn]

You mentioned transportation in the intro, but didn't even give a nod to the tens of thousands of truck drivers who actually do that transportation with refrigerated trailers. My husband is one of those drivers! If you are also, thank you!

[@Beryllahawk]

So much food science! So many things made me think about Good Eats! Ahhh!

[@danielzelaya2058]

Please do an Audio Engineering video!

[@unleashingpotential-psycho9433]

That cupcake looks yummy!

[@NoxMarcus]

This video would have been better with some actual images from Ice cream mass-production

[@shreyasivaram4097]

I wish the teachers in my school were as interesting as this video

[@brinnar.2732]

Well you said ice cream, almost like click bate. Food engineering is an interesting topic in health and diet studies that few people really talk about. B#

[@leeoswald668]

I used to be so worrying about all this stuff I couldn't imagine not keeping my food in the fridge, etc But then I moved to Vietnam... And now I know that it's not necessary even to store meat in the fridge (for a short period 😂) It's not even about milk, especially sterilized milk Eggs? Outside of the fridge Almost everything is outside

[@obeytweety]

NOT ME EATING ICE CREAM RIGHT NOW....

[@prplfire7918]

Let’s all scream @ ice cream

Even the most expensive store ice cream pales in comparison to bucket churned ice cream

[@camiloiribarren1450]

Wow, that thought bubble in the intro is pretty much how most of us like to feel when we are lazy

[@SaberusTerras]

I saw that cheeky Wilhelm's Scream reference in the title card.

REAL Ice Cream isn’t mass produced.

[@eldersprig]

not allowed to eat it anymore, so yall can eat more air. more air. more air.

[@Dustman3400]

Then you’re stuck making it yourself. Even if you go to a local business that makes it in house they still employee mass production techniques, albeit a smaller scale than the grocery store ice cream. They’ve got a lot of expensive equipment to make that ice cream.

[@elijahfordsidioticvarietys8770]

Well store bought ice cream sucks
