(b)The coatings are formulated from optional substances which are:
(1)Substances generally recognized as safe for use in or on food.
(2)Substances the use of which is permitted under applicable regulations in parts 170 through 189 of this chapter, by prior sanctions, or approvals.
(3)Substances identified in this paragraph (b)(3) and subject to such limitations as are provided:
