2. Tea was adulterated in 18th century London because it was brought all the way from China and was very expensive. 3. Artificial gassing tricks the tomato into turning red so that it looks ripe, but it doesn’t have the flavor of a ripe tomato.
4. Antioxidants are added to oil-containing foods to prevent the oil from spoiling. Chelating agents stop food from discoloring. Emulsifiers keep oil and water mixed together. Flavor enhancers improve the natural flavor of foods. Tickening agents absorb some of the water present in food and make food thicker. They also keep oil, water and solids well mixed.
