What food has water vapor?

Answer 1

Most food is consumed below waters boiling point (212 °F), otherwise people would be at risk of burning themselves.

However, many foods are prepared with the help of steam or water vapor. For example one might steam vegetables or rice in the cooking process.

When baking a cake, steam, as well as carbon dioxide and other gases will help it raise (and perhaps fall).

However, that is only part of the story. All liquids will have a "partial pressure" based on the temperature and the concentration of the different solvents or components.

When that pressure reaches atmospheric pressure (1 ATM), the substance boils.

But, even below the boiling point, the liquids release vapors. This may help carry the aroma of a good cup of coffee or hot chocolate to your nose. Or... notice that a cup of hot water (without tea or coffee) will have a smell... and perhaps even visible steam?

Even a cup of cold lemonade will have a partial pressure, and release some water vapor.

The humidity in the air, of course, is the water vapor in the air. If the humidity is less than the due point, the water will tend to evaporate. If it is above the due point, it will tend to condense.
