There are rumors since many days that soft drink mountain dew contains pig fat. Now this is really disgusting but as its one of my favorite soft drink, I enquired about this matter. So this pig thing came in? you should have seen that Dew is a yellow colored drink and the substance used for giving this color is Yellow 5 which is chemically a mix of trisodium 5-hydroxy-1-(4-sulfonatophenyl) (4-sulfonatophenylazo)-H-pyrazole-3-carboxylate and subsidiary color matters together with sodium chloride and/or sodium sulfate as the principal uncolored components. So you found any pig here? Certainly not! Yellow 5 is derived from coal tar, not pig. So where is the pig? Actually the color yellow or just any color is also called pigment (recall green pigment chlorophyll in leaves we studied in school) so some uneducated people thought it as something associated with pig. How sad, God help these people, don’t know how they survive. Other rumors like drinking dew (yellow 5) will make you infertile are bull shit. It’s approved by FDA and not only in Dew; yellow 5 is widely used in coloring many food items since years.
