On March 15, 1977, the FDA promulgated a new standard of identity for mixed nuts in 42 FR 14475. The present standard, as modified by 58 FR 2885, Jan. 6, 1993, requires that mixed nuts must contain at least four different varieties of tree nuts or peanuts. (Products with three or fewer varieties are now commonly labelled as simply "mixes".) The container volume must be at least 85% filled, and the label must state whether any peanuts are unblanched or of the Spanish variety.
