Norma,
Where this project goes will depend to a great degree on the results of your bake test next Tuesday with the two dough balls. But, what I will tell you is that I trust the numbers for the BforB flour and the KAAP flour. I also trust the results of your recent hydration bake test and the gluten mass test. Those tests were done with a real live Pepe's dough ball and have nothing to do with the Pepe's Nutrition Facts or ingredients list. There is no way to know if those Nutrition Facts are correct or accurate, and there is no way to determine whether any errors are intentional or unintentional. But I will tell you that you can't just hide ingredients from the ingredients list. People have allergies, some may be vegetarians or vegans, or may have other health or nutrition related issues that you don't dare omit ingredients from the ingredients list. I recently sent an email to the FDA about whether bromates, if used, are required to be recited in ingredients lists. The FDA is pretty good about responding to consumer questions. If they do respond, the answer may also give us a better idea of what other kinds of ingredients dare not be omitted in ingredients lists. I also feel comfortable with my analysis of the flours, mainly based on the results of your gluten mass test. Of course, Pepe's, or its successor, may be using a flour milled to their specs. There is nothing I can do about that. The best I can do is say what I think they are using as a flour from a protein standpoint that fits the Pepe's Nutrition Facts (except for the carbohydrates).
As far as Pepe's as a business enterprise is concerned, I am sure that you did a lot of searching in an effort to try to determine who might now be behind Pepe's, including going through all of the hits that Dave turned up in his Google search. I, myself, went down the same path. However, I do think that it might be worth a call to Wal-Mart to see if you can find out who is now behind Pepe's. Unless they are phasing out the existing inventory of Pepe's dough balls, there must be someone making the Pepe's dough balls that are in the Wal-Mart stores. If you can get an answer out of Wal-Mart, then that might be a lead that we can follow up on.
