Final answer:
The bread in question contains wheat, sourdough, and semolina, but the statement does not clarify which ingredients are absent, and cannot be completed without further information.
Step-by-step explanation:
The bread described in the question is a proprietary blend, which means it's made according to a specific recipe owned by an individual or a company. The ingredients list provided does not specify what the bread does not contain, so without additional information, we cannot complete the sentence accurately. However, based on the ingredients listed, we can infer that the bread does contain wheat, sourdough, and semolina, among other ingredients, as specified in the details.
