Sunday Trivia - What is Pectin?

What is pectin?

Pectin is a gelling/thickening agent.  You can generally buy it in powder or liquid form from stores.  But what it is, is actually a complex form of carbohydrates called polysaccharides.  It's found in the cells of certain fruits and plants.  Wikipedia has more info on the chemical information as well as a list of common fruits and vegetables, and their level of pectin.  Citrus peels has about 30% of pectin, which is a lot compared to, say, cherries, which has only about 0.4%.
So when one is making jam/jelly/preserves from a fruit that does not have or does not have enough pectin in it to thicken, one adds pectin.
