A food shall be deemed to be misbranded:
However, spices, flavorings and colorings, other than those sold as such, may be designated as spices, flavorings and colorings, without naming them. To the extent that compliance with the requirements of paragraph (b) of this subsection is impractical or results in deception or unfair competition, exemptions shall be established by rule promulgated by the department.
