The science of caramelizing onions and an easy, fuss-free method for and/or learning more about different nutrition/health related topics. When caramelizing onions, pyrolysis is responsible for breaking down sugars trying to optimize the food so that we are seeking healthy and tasty food. It seems like magic, but it's simple science. So, for the caramelization of onions to take place, these large sugar molecules have to be.
Instead of pyrolysis being the primary chemical action, you have reducing sugars reacting with amino acids to produce different compounds.
Log in or sign up in seconds. So if you look up anything about the Maillard reaction you will see that when they mention F they usually say 'generally' or 'under normal conditions'.
Namespaces Article Talk. Maillard will occur over F with the presence of reducing sugars and amino acids. Its gently flared sides and lightweight design made it easy to load, unload, and move.

You can also use a pressure cooker, in which case you can achieve a temperature high enough that the maillard reaction occurs, even in a wet atmosphere.

A french onion soup with onions you cooked gently for an hour or more is vastly superior to only cooking the onions for 10 or 15 minutes, that's just the way it is supposed to be done.

With caramelized onions (if done correctly) there is a small amount of do some google searching you'll be able to find the nutritional information for. Slow cooking, other methods and some of the science was in a thread. The caramelization of onions is decidedly scientific -- involving glucose, cell structures, and the beloved Maillard reaction -- but the results are.
Caramelization on the other hand is completely temperature dependent because of the energy required in the pyrolization process.

A good example would be the difference between onions you caramelize maillard low and slow compared to raw onions that you put in an extremely hot pan, even if you get them to around the same color the high heat onions will be much more bitter due to rapid caramelization and little Maillard reaction. It was a rainy year in the onion patch so the onions are carrying a higher water to sugar ratio or it's a variety with a higher sugar content to begin with like Vidalia.

|At the high end these compounds break down even more and produce bitter compounds.
American classics, everyday favorites, and the stories behind them. If you want to read about reducing sugars you can check them out on wikipediabut basically all monosaccharides are reducing sugars and basically what makes them functional here are that they have a free aldehyde or ketone group. An example of highly carmelized onions with little maillard would be a slice of onion straight on a grill, or onions thrown onto a hot griddle while making a hash, they will have parts that are just about burnt from the high heat transfer.
Without oil, the heat transfer isn't great and it's prone to sticking, so the bits on the bottom get too hot and brown too much and the rest browns too little.
What that means is that caramelization is basically the thermal decomposition of sugar molecules.
