We use Brix values to calculate the labeled percentage of juice from concentrate found in a
juice or juice beverage using the minimum Brix values provided in 21 CFR 101.30. We have
determined that single-strength (100 percent) juice contains at least the specified minimum
Brix for each single-strength juice listed in 21 CFR 101.30.
You can calculate the added sugars declaration when a product contains concentrated fruit
juice in several ways. If you know the sugar content of the single strength fruit juice before
it is concentrated and added to the product, because the amount of sugar from the single
strength juice has been determined through chemical analysis, you may use the known sugar
content when determining the added sugars declaration. You also may choose to use the
Brix values provided in 21 CFR 101.30 when determining the sugar content of a single
strength fruit juice product, which is then used to calculate the added sugars contributed to
the product by the concentrated fruit.
We require that, when sugars that do and do not meet our definition of added sugars are
present in a food, manufacturers make and keep written records of the amount of added
sugars added to the food during the processing of the food, and if packaged as a separate
ingredient, as packaged (whether as part of a package containing one or more ingredients or
packaged as a single ingredient) (21 CFR 101.9(g)(10)(iv). If you use Brix values provided
in 21 CFR 101.30 to calculate the amount of added sugars in a product containing fruit juice
concentrate, you must document this information in the records regarding the amount of
added sugars added to the food during processing (21 CFR 101.9(g)(10)). If you use the
amount of sugars present in a single strength juice and/or a fruit juice concentrate that is
determined through chemical analysis when calculating the amount of added sugars in a
product containing fruit juice concentrate, you must document the analytical information in
the records that you make and keep (21 CFR 101.9(c)(6)(iii)).
