2. The standards of enrichment so established may prescribe maximum
and minimum amounts of vitamins, minerals and other nutrients which
enriched products must contain, or such standards may prescribe single
level requirements, with provisions for a reasonable overage within the
limits of good manufacturing practice. In establishing such standards of
enrichment, the commissioner shall conform, insofar as he finds
practical, to standards of enrichment promulgated by the secretary of
health, education and welfare pursuant to the federal food, drug and
cosmetic act, and acts amendatory thereof. Any standard established by
the commissioner after public hearing may be amended without hearing, if
the amendment substantially conforms to standards promulgated under the
federal act.
