6 Fun Facts The creamy middle of a Twinkie is not cream at all but mostly Crisco, which is hydrogenated vegetable oil

7 Fun Facts Red dye #40 is derived chemically from coal tar

8 Don’t want artificial dye?
All “natural” red dye is derived from cochineal, an insect native to Central and South America. Females are dropped into boiling water or crushed to kill them. From their bodies, a red substance called carminic (or kermesic) acid is extracted One million corpses = One kilogram of carminic acid

9 Two forms of cochineal dye
Crude cochineal extract is made from the dried and pulverized bodies of the insects. Carmine is a more purified form made by boiling the dead insects in ammonia or sodium carbonate, filter, and add alum. The alum reacts with the carminic acid solution to form a bright red compound. Lime can also be added to get a shade of purple
