Will the sandwiches made in the morning go bad by noon?

When making sandwiches, the ingredients should be cold.

When this is done, put it in a fresh-keeping bag and take it out at noon.

Don't use hot and cold ingredients together, which will cause steam if you put it in a fresh-keeping bag immediately.

This will also accelerate the growth of bacteria. The taste of food will also get worse.
