Any food is adulterated if it is confectionery and any one of the following conditions exist: (a) It has partially or completely embedded therein any nonnutritive object, provided that this subdivision shall not apply in the case of any nonnutritive object if, in the judgment of the department as provided by regulation, the object is of practical functional value to the confectionery product and would not render the product injurious or hazardous to health. (b) It bears or contains any alcohol in excess of 5 percent by weight. (c) It bears or contains any nonnutritive substance, provided that this subdivision shall not apply to a safe nonnutritive substance that is in or on confectionery by reason of its use for some practical functional purpose in the manufacture, packaging, or storage of the confectionery if the use of the substance does not promote deception of the consumer or otherwise result in adulteration or misbranding in violation of any provision of this act; and provided further that the department may, for the purpose of avoiding or resolving uncertainty as to the application of this clause, issue regulations allowing or prohibiting the use of particular nonnutritive substances.
