Question

heat something up it expands why then does bread shrink when toasted and meat shrink when cooked

Answer 1

The moisture is toasted out of the bread, the fat in the meat is cooked out therefore they shrink in size. ;-)

Answer 2

When you heat up things, they don't always expand. Bread looses moisture when toasted so it shrinks (but the moisture, meaning water in the bread expands) and meat shrinks as it looses water, and some fat. Also when you cook some vegetables like cabbage, shrinks in volume because the heat softens the structure.

Answer 3

The scientific reason has to do with dehydration. Toasting bread dehydrates the bread and thus it shrinks. The same happens with meat as the moisture and fats are drawn out by heat the meat retracts and becomes smaller. In order to keep the meat from drying out and becoming small and whithered you need to make sure not to over-cook it or to cook it with a liquid to keep it plumped up. If you notice on the package of hot dogs, turkeys, etc. they are often injected with juices to help keep them fat and plump while being cooked. This is also why when roasting a turkey, chicken, roast, etc. it is advised that one bastes it often with water, broth, or similar.

I know people here made fun of you asking this question, but it isn't a stupid question. Not knowing your age, I assume it was asked honestly. I hope we were able to help you better understand.

Answer 4

The moisture is toasted out of the bread, the fat in the meat is cooked out therefore they shrink in size.

Answer 5

You are cooking the moisture out of bread when it is toasted. Meat has fat and water come out of it when it is cooked.

Answer 6

It's also to with any sinew or gristle in the meat. It shrinks when cooked and never tenderises so cut off as much befoer cooking.
