Combine marinade ingredients in a gallon zip lock bag, mix it up well. Add the pork tenderloins to the bag, coat them well. Refrigerate 12-24hours.
Preheat oven to 325 degrees. Place tenderloins on a wire rack or broiler pan so the air can circulate, reserve the marinade. Bake 1.5 hours or until the internal temperature reaches 150 degrees. Filp the tenderloins over and baste every 30 min with some of the reserved marinade.
Remove tenderloins from the oven, let them cool to room temperature. At this point you can refrigerate or freeze until ready to serve.
When ready to serve, thaw under refrigeration (if you froze them). Slice into ¼" rounds and arrange on platter with spicy brown mustard and sesame seeds.
