Almond Joy's got nuts, and refrigerant


No really. I had no idea. I have this bad habit of reading the ingredients to the foods I eat, and I always feel like I'm back in my ochem texbook when I come across processed foods. I'm also literally addicted to Wikipedia, and so when I eat something this gross and wiki it, I tend to never eat the object again.

Sulfur Dioxide
(some quotes from Wikipedia)


  • Further oxidation of SO2, usually in the presence of a catalyst such as NO2, forms H2SO4, and thus acid rain.

  • Sulfur dioxide is sometimes used as a preservative for dried apricots and other dried fruits due to its antimicrobial properties, it is sometimes called E220 when used in this way. The preservative is used to maintain the appearance of the fruit and prevent rotting. Its presence can give fruit a distinctive chemical taste

  • Sulfur dioxide is also a good reductant. In the presence of water, sulfur dioxide is able to decolorize substances. Specifically it is a useful reducing bleach for papers and delicate materials such as clothes. This bleaching effect normally does not last very long. Oxygen in the atmosphere reoxidizes the reduced dyes, restoring the color.

  • Sulfur dioxide is also used to make sulfuric acid

  • Sulfur dioxide has no role in mammalian biology. Sulfur dioxide blocks nerve signals from the pulmonary stretch receptors (PSR's) and abolishes the Hering-Breuer inflation reflex

  • Being easily condensed and with a high heat of evaporation, sulfur dioxide is a candidate material for refrigerants. Prior to the development of freons, sulfur dioxide was used as a refrigerant in home refrigerators

  • Sulfur dioxide is a versatile inert solvent that has been widely used for dissolving highly oxidizing salts. It is also used occasionally as a source of the sulfonyl group in organic synthesis. Treatment of aryldiazonium salts with sulfur dioxide affords the corresponding aryl sulfonyl chloride.[

  • [edit] Threats to Health
    Sulfur dioxide acts as an acid. Inhalation results in labored breathing, coughing, and/or a sore throat and may cause permanent pulmonary damage. When mixed with water and contacted by skin, frostbite may occur. When it makes contact with eyes, redness and pain will occur

  • and as a side note: sodium metabisulfite was also added to the product t, which when mixed with water turns into more sulfur dioxide, as if the first dose wasn't enough.

And I just ate this sh*t. It was a Almond Joy bar. And that was only ONE ingredient.


Damn... I was just beginning to like that fake coconut taste.
