In the US, food labels are required to provide an ingredients list. One common phrase on labels is "contains 2% or less of." For example: "Pork, water, contains 2% or less of: salt, spices, sodium phosphates, dextrose, autolyzed yeast extract, caramel color." (Bonus points for identifying what that ingredient list is for.) Does the 2% apply to each item in the list individually, or do all the items sum up to being less than 2%?
This is sort of academic, I suppose, but I like to know what goes into the ingredients I use.
