The Science of Fermentation: Lactofermentation

Fermentation is one of humankind's path-breaking discoveries. The fact that we can persuade billions of tiny microbes to make our food delicious, longer-lasting, and more nutritious is rather astonishing when you think about it.

This is the absolute BEST intro to food fermentation! I have been looking for a scientific explanation to guide my practical applications. I will sub and buy book.

BTW, I came to love idli during my travels in India. Glad my experience helped me follow your explanation too.

Recipes:
- Onions, garlic, chilli, fruit (e.g. pineapple) - 3 weeks = hot sauce
- Cabbage, salt - few weeks = sauerkraut
- Cabbage, spring onion, chillies, radish, carrot, salt (squeeze cabbage so water covers all) - 2-3 weeks = kimchi

My parents time left over rice and curd was morning meal. I used to feel sorry that they didn't have proper breakfast. Both lived to ripe old age. My grandkids start their day with rice Krispies or Choco puffs with zero nutrition . Your video was very informative. Thank you

[knowledgeiseverything]

Excellent! Wish we had teachers like you to teach science / microbiology.

[RayRay-rkbd]

Excellent job Sir. Wish you millions of subscribers. If you're a student watching, tell your friends. If you're a teacher watching this. This is the real art of teaching. Going from known to unknown, keep it simple, get excited and enjoy the subject and circle back .

Son, thnq 4 the wealth of knowledge u'v shared w/ me taking me step by step thru yr video...was such a pleasure listening 2 u. I bless u, 11Son in the name of YESHUA HAMASHIACH .

This 10 minute video taught me so much about things I'm passionate about - Food and Science. Your simple, informative and "science is cool" approach to explain confluence of these two areas really resonates with most people who find such things worthwhile and relaxing. Have ordered your book and waiting for the fun and to learn more. Thank you and more power to you sir for making more of such videos.

[jayuknair]

Big fan of yours already sir! This is the first time I'm watching your video. What a wealth of information and such simplicity in presentation that anyone can easily understand!

[debaratabasu]

The part about tacit knowledge and scientific understanding is very vital.. Probably more than the concept of fermentation! Very well done ❤

[budmonk]

The last part especially is gold. Everytime someone said, our ancestors knew this when the rest of the world were in caves, I would audibly groan. In accumulating tacit knowledge, perhaps several million people died, but understanding the scientific knowledge can save lives and feed millions and move onto the next stage.

One of the best videos or channels on YouTube. I would happily pay any amount of money just to listen to this guy speaking about food & the cooking techniques! Awesome stuff Krish! ⭐️✨

[sriparnamondal]

It's the first video that I'm seeing from your channel. In love with the way you're describing the microbial process with the recipe... ♥️
I've a request to you...can you suggest me some books on ancient fermentation recipes !

[vaibhavsingh]

I have seen some of your videos in ig reels.
They were also good, i don't know why you don't have much subscribers.
The dialogue delivery, camera work all are good and content is just pure gold just like that fermented water ;)

[ramprasanthudhayabaskar]

Best video about fermentation I have ever seen.

[fly]

These knowledge is just gold thank you❤

[mohammedarif]

Why can't our schools and colleges give us knowledge of this depth and clarity? Every successive government brings new education policy and adds complications only. Standard of graduate electrical engineer is such that a fresh pass out can't use multimeter even. We need to improve on quality of education.

[wealthyhealthyjoyfulever]

Clarity at it's best
நன்றி நண்பரே🙏🙏🙏🙏❤️

[prakash]

very nice video. Thanks for explaining the science behind Idly and Dahi. Missed one point about how the balance of Good bacteria vs Bad bacteria in body is of importance. All the nutritional experts in US started saying this in last 10-20 years. and I go...aha! that's what my ancestors are eating for thousands of years. small portion of yogurt rice after every meal and Idly/dosa for breakfast. Your recipe of Yogurt and idly batter is perfect. It is useful to use heat (especially in colder regions of USA/Europe or Northern India to help fermentation. Keeping batter in oven with light bulb on, OR keeping a light bulb on on top of batter gives small heat in colder region. This is hardly a problem in India though. Thanks for a nice video.

[krishkurup]

Loved every part of this video....and the finish with a flourish ....tacit understanding vs scientific explanation....that was epic

[srikarsagi]

Million dollar gold worth starts at 19:50 onwards "Oh our ancestors already knew this"
Having a Tacit knowledge of getting healthy-benefits doesn't mean they (our ancestors) understood underlying with water/oxygen etc" -- to exploit science of fermentation, you don't have to know the scientific of microbs --you just know fermented food gave-good health & you repeat it over generations
