@alejandrac1446 Год назад

Thank you for this video and introducing more people to the importance of nixtamalization. One thing I must add, because I did some of these experiments, is that the difference between tortillas made with maseca and proper masa is more on the mechanical properties. If you compare elasticity of both versions you can see how much more brittle maseca tortillas are. This can lead to a lot of wasted tortillas because they don’t reheat as well as tortillas made with proper masa. Now there is definitely a flavor difference, you just need to eat more good tortillas and you’ll start noticing ☺️

Calcium hydroxide is readily available in nature when limestone comes into contact with water, or from sea shells for example

@TysonJensen Год назад

@@joshgiesbrecht7060 So... turns out that if you dissolve calcium carbonate in water (like sea shells &c) then dry out the water, you get limestone. But limestone isn't pure calcium carbonate. It's a blend of calcium carbonate and calcium oxide. Most oxides are super-stable and don't react with much. But calcium oxide is unstable, and can react with water to make calcium hydroxide. If you heat the water first, the reaction is reliable enough to nixtamalize corn. No one is sure how exactly the Mayans figured out that doing this would make field corn edible. Thanks to VAXX-1 for pointing out that limestone is the relevant google search term to unravel the tapestry.

@joanhuffman2166 Год назад

Sometimes, they just use ashes from the cooking fire, or they use quick-lime. Lime is made by heating limestone in a kiln.

@TysonJensen Год назад

@@joanhuffman2166 regular cooking fire ash wouldn't work, you need calcium hydroxide, which is a fairly specific ask of an ancient culture. They certainly could have made lime and then used that, but you don't need to. Just throw some limestone in a pot of boiling water and you won't get a lot of calcium hydroxide, but. you'll get enough to make the corn edible. (you need to be burning bone or something with calcium, which is possible but seems a stretch when compared to "boil this rock with the corn and it works better")

I think something got lost in the edit around the pellagra. I think the point of that was that (I'm guessing) while corn was consumed in Europe, they didn't prepare it using CaOH ... This seems to be implied, but it just ends up feeling like a tangent with no connection to the narrative.

@joanhuffman2166 Год назад

You are correct. The knowledge of how to process maize did not travel with it. I know that in the South, many cooked corn cakes in ashes, which will do the trick too. Then people decided that was "dirty" and cooked it in a pan with no ashes. Pellegra followed after, at least among the poor who didn't eat much else. In other areas, Southern Europe, Africa, and China people treated maize as they treated other cereals. Pellegra was a consequence for many.

@hedgehog3180 4 месяца назад

I think even today maize is mostly boiled in Europe, though maize flour and products based on it have become more common. Though pallegra isn't an issue today since people get their vitamins from other cereals like rye or just take supplements.

@FernandoJRodriguezFernandoJRM Год назад

Here’s a nitpick: in México (where Maseca comes from) we never call it “masa harina”. That’s a term I’ve heard only for Colombian and Venezuelan corn flour, which they use for “arepas” (which are much thicker than tortillas). Also, we only call it “masa” once the corn flour is mixed with water (and use the same word for dough made with other types of flour). The dried corn flour for tortillas is simply called “harina” (i.e. “flour”), or more commonly, “Maseca”, which is likely a portmanteau of “masa” (dough) and “seca” (dry).

but the fatty acid composition of corn is like : toxic....

@joanhuffman2166 Год назад

It kept the indigenous Americans healthy for ages. They did include many other foods in their diet. Peanuts and avocados would have good sources of vegetable fats. Many outside of the Americas have heard about the alleged deficiencies of maize. It is low in lysine, an essential amino acid. It is low in niacin, vitamin B3, and now the claim that the fatty acids are toxic. All of these claims are based on what happens with maize when it is removed from its cultural context. Indigenous Americans eat many foods with their maize, many of which are rich in lysine. Prominent among these foods is huitlacoche or corn smuts, corn truffles, or corn mushrooms. Corn smuts are considered a plant disease and treated as a cause for grief outside of Mexico. Huitlacoche is a blessing in disguise, a tasty fungus rich in the missing amino acid. The missing niacin is due to the fact that maize needs the nixtamalization process described in the video to chemically unlock the niacin, which it does have. The claim that the fatty acids are toxic is based on the fact that we silly modern people extract the tiny amounts found in corn and consume quantities that no ancestors could have hoped to obtain. The Indians of Mexico had avocados, peanuts, and other things as better sources of fats.

Enjoyed the video except for your liberal, politcally correct, virture signaling by bashing Columbus to make points with the left.

Yeah I agree. The way he kept bashing Columbus like if he was a thief or something. It's not like he got off the ship and said ooh this strange vegetable I'm going to steal it and take it back. It was probably more akin to This is strange I bet his majesty would get a real kick out of this. I mean seriously how many of us have gone someplace saw fruit tree picked a piece of fruit and said You know what I think I'll try to grow this at home. OH MY GOD I'M A THIEF

Oh no he criticized a man that was so evil that even his contemporaries thought he was evil and the Spanish crown revoked his govenorship because he was so tyrannical and sadistic. Surely we must never criticize this man who even the Spanish Inquisition thought was too much.
