Food Unwrapped - Season 15 Episode 05: Soft-shell Crab, Blue Dye, Pork Pies

Come back again to introduce some of the best new scenes in season 15 where Kate finds out how the way tea drinks affect her taste. Matt looks at the difference between bubble gum and chewing gum, and finds unusual use of chewing gum. On the other hand, maybe there will be a parasite hiding in our sushi, and could M & S track all the beef burger back to the cow? It is a question that seems very puzzling.
