milk

[chitrangda]

can any one let me know the chemical properties of cow and soy milk.

[curiouslou]

Wasn't sure what properties you wanted listed but ok

 

btw...this is just information on the world wide web, i am not a milk expert, although i do drink a bit of it.

 

COW MILK

 

pH - 6.5

fat content - (Whole milk) 3-5%

Water content - 80-90%

Boiling point - approx 100 degrees C (dependent on numerous factors)

Protein content - 3-5%

 

SOY MILK

 

pH - 7

fat content - 2%

Water content - 60-80% (I guess this depends on manufacturing process)

Boiling point - (I cant give anything concrete but i assume close to that of water)

Protein Content - 3.5-5%

Now where was th fun in that. PLUS the question asks for the properties of soy milk as well, so your answer isnt perfect

what exactly is it that you want? we're glad to help, just some specifics would be better, maybe the organic chem section is better too for this thread

 

milk is just a homogenous mixture of lipids and nucleic acids, at least that's what I thought, but i'm really not that sure. i kno that it has lipids and water though!

Milk is not homogeneous, it's a stable emulsion ... or can you call an emulsion homogeneous too?

 

(Well... stable emulsion for a couple of days, and then it evolves into a monster that will attack you once you open the fridge).

i was working on a project releating extraction of soy milk and its comparision with milk..i really tried to search of their common properties but failed to know some...i wanted to know abt chemical structure of soy and cow's milk.

Milk composition: http://en.wikipedia.org/wiki/Milk

Soy milk composition: http://en.wikipedia.org/wiki/Soy_milk

Soy composition: http://en.wikipedia.org/wiki/Soy#Protein.2C_vitamins.2C_and_minerals

 

But after all the previous posts, I am certain that you checked these wikipedia websites already... what else do you need? You'll have to be more specific now to get more info.

 

I am afraid that both milk and soy milk are rather complex mixtures of biological molecules, of which many are polymers. Those polymers in turn often consist of several different monomers. Then to top it off, they are both emulsions. What do you want to compare? I hope not the complete list of components? (It might be longer than the phonebook of India).

[chitrangda]

i want to know about the %age of following in soy milk

vitamin a

vitamin b1(thiamin)

riboflamin(vitamin b2)

vitamin b12

vitamin D

vitamin E

calcium

Magnesium

potassium

please help someone please...

im stuck on it and have tried my leavel best to do some thing but failed:-(

This will answer some of your questions but it's in no way a scientific source... I suspect these things may well alter...
