Technically salt can be any ionic compound formed by reacting an acid and a
base, but most of the time the word is used to refer to table salt, which
is sodium chloride or NaCl. So, you know salt contains sodium, but the two
chemicals aren't the same thing.
What Is Sodium?
Sodium is a chemical element. It is very reactive, so it isn't found free in
nature. In fact, it undergoes spontaneous combustion in water, so while
sodium is essential for human nutrition, you wouldn't wan... 阅读全帖 |

Sodium is also found in many other ingredients used in food processing.
Examples of sodium-containing ingredients and their uses in foods are:
Baking powder--leavening agent
Baking soda--leavening agent
Monosodium glutamate--flavor enhancer
Sodium benzoate--preservative
Sodium caseinate--thickener and binder
Sodium citrate--butter, used to control acidity in soft drinks and fruit
