jackal10, I agree with you for most of what you said with a few minor variations: Point a: You're right on the money. Point b: Remember that the cell walls are also fat. By the time you get to 100C, they have long been melted and denatured. This is different for plants, but they have a different cellular structure, relying on cellulose enclosures around cells, so you need higher temperatures to rupture those structures. You are disrupting a supercellular structure when you get to the point that water is actively vaporizing "deep" inside the tissue. point c: Maillard reactions are right on the money, but these are mainly anhydrous reactions. They don't happen quickly in the presence of water, and don't happen with much speed until you get to a screeching hot temperature of 300+ Farhenheit. This is why you sear at such a hot temperature. You can get these to happen in bacon earlier and more quickly if you really crank up the temperature, but then you'll scorch the bacon and have it done in an un-even manner. What is happening more are nitrate and nitrite reactions occuring with the myoglobin in the cells which give it the reddish color. Those happen at lower temperatures than the Maillard reactions. These start gaining appreciable speed at about 60 C, or a decent smoking temperature for... bacon and ham. I personally think that as you increase the temperature, more of the fat leaves the structures and the proteins in the connective tissues are able to denature into tighter and tighter structures which is why the fatty areas shrink so much. It is well-known that meat shrinks during the cooking process, and it shrinks for several reasons: water loss, fat loss, dissolution of essential parts, and denaturation of proteins into tighter packed and less-ordered structures (which is why you can tell a cooked piece of meat from a fresh one by jabbing it with your finger... aside from the burns). The maillard reaction explains the brown and the crispy, but there are many other things going on during that stage. [OT] When I apply for entry into a food science graduate program, should I go into oenology, or something else? Anyone have suggestions, since this is the 'geek' thread? I'm applying to the University of Nebraska. Edited with more information on Maillard.
