CPG Sec. 515.600 Candied Citron - Labeling
The term "Candied citron" is generally recognized in the trade, and by the consumer, to be applicable only to the candied peel of fruit of the citron tree, Citrus medica L., variety genuina Engl., a citrus fruit similar to the lemon but larger and possessing a thick rind of characteristic flavor.
The rind of the citrus melon, Citrullus vulgaris Schrad., is often used in a similar manner to candied citron. The candied rind of this variety of watermelon, may not be designated as "Candied citron." It should be labeled "candied citron melon," "Candied watermelon," or some similar designation that is not false or misleading.
It is also considered that such terms as "American citron," "Candied domestic citron," or the like, are not correct designations for the candied citron melon and when used will be deemed misbranding, except when applied to the American product of the citrus fruit "citron," described above.
