FOOD UNWRAPPED explores how our food is really made and the industry secrets behind our favourite produce. Reporters Matt Tebbutt, James Watt, Martin Dickie and Kate Quilton travel the globe to discover just how the food we love is mass produced. The series contacts supermarkets and producers with simple questions about the food we buy: What's the wax on lemons?; What are the bacteria in probiotics?; What is formed ham?   Traveling to the food producers who supply the supermarkets to investigate, from Liverpool to Swaziland, and Thailand to Spain. Taking the cameras behind the doors of factories worldwide, the inquisitive food lovers meet food technicians, scientists, factory owners, growers and producers in order to reveal weird and wonderful facts we never knew about our food.
