（c） It is used or intended for use: （1） In maturing and bleaching of flour in a quantity not more than sufficient for such effect; and （2） as a dough-conditioning agent in bread and roll production at not to exceed the quantity of hydrogen peroxide equivalent necessary for the artificial maturing effect.
