Stir soy sauce, honey, ketchup, brown sugar, rice wine, hoisin sauce, red food coloring, and Chinese five-spice powder together in a saucepan over medium-low heat; cook and stir until just combined and slightly warm, 2 to 3 minutes. Pour the marinade into the bag with the pork, squeeze air from the bag, and seal. Turn bag a few times to coat all pork pieces in marinade.
