Cut a piece of wood or cardboard to use as the base of your train track, at least 24" long and 3" wide. Using one of the long plastic angle pieces as a straightedge, draw five lines lengthwise on the base as shown in Figure 3. Draw a center line down the middle of the base. Melanin is what turns the fruit and vegetables brown. This reaction, however, usually does not happen within fresh fruits and vegetables because the PPO and the phenolic compounds are separated in produce plant cells. The enzymatic browning process is only triggered when PPO, phenolic compounds, and oxygen come in contact with each other.Chemically, agar is a polymer made up of subunits of the sugar galactose, and is a component of the cell walls of several species of red algae that are usually harvested in eastern Asia and California.
