Is it permissible to consume products containing stabilizers and preservatives of unknown origin, which are rumored, without confirmation, to contain something prohibited?

The fundamental principle regarding the items mentioned is permissibility, unless it is known with certainty or strong probability that they are mixed with impure or prohibited substances. Therefore, unless their packaging states that they contain unlawful ingredients or impure materials, it is permissible to consume them. This is because mere doubt does not warrant discarding food, as the rule among scholars is: "Food is not discarded due to doubt." However, refraining from them out of piety is more virtuous.
