2.3.1. Deterministic edits
Deterministic edits reveal errors that most likely need to
be corrected. These edits are conducted to identify foods
that may have been coded in the wrong form, such as a
concentrated juice that is usually consumed in the
reconstituted form. Other foods covered by these checks
are dry instant coffee or tea, dry milk, other instant
beverage mixes, mashed potato flakes, dry baby formulas,
and condensed or dry soups. These foods are generally
coded in their reconstituted forms. However, sometimes a
code for a dry or concentrated form may be used,
accompanied by another code for a liquid food. The two
items are linked with a ‘‘combination code’’, to let data
users know the foods were mixed together; for example,
concentrated lemonade mixed with ice tea. Edit checks find
occurrences when dry or concentrated forms of the abovementioned
foods have been coded without a combination
code, and they are reviewed according to guidelines for
each edit. As an example, the guideline for dry coffee is
illustrated in Table 2.
