An article of food which does not contain any added poisonous or deleterious ingredients is not deemed to be adulterated or misbranded in the following cases:

(1) In the case of mixtures or compounds known as articles of food under their own distinctive names and not an imitation of or offered for sale under the distinctive name of another article, if the name is accompanied on the same label or brand with a statement of the place where the article was manufactured or produced;

(2) In the case of articles labeled, branded or tagged so as to plainly indicate that they are compounds, imitations or blends and the word “compound,” “imitation” or “blend,” as the case may be, is plainly stated on the package in which it is offered for sale. The term “blend” as used in this subdivision shall be construed to mean a mixture of like substances, not excluding harmless coloring or flavoring ingredients used for the purpose of coloring and flavoring only. Nothing in this chapter shall be construed as requiring or compelling proprietors or manufacturers of proprietary foods which contain no unwholesome added ingredient to disclose their trade formulas, except insofar as the provisions of this chapter require in order to secure freedom from adulteration or misbranding.
