Pectin

Pectin is a versatile ingredient with various uses in cooking, baking, and as a dietary supplement. Here is a detailed product description of pectin based on the search results:Gelling Agent and Thickener: Pectin is a soluble fiber known as a polysaccharide, which is a long chain of indigestible sugars. When heated in the presence of liquid, pectin expands and turns into a gel, making it a great thickener for jams and jellies13. It forms a mesh that traps liquid when heated with sugar and acid, setting and suspending pieces of fruit as it cools.
Nutritional Value: Pectin is a fiber and contains almost no calories or nutrients. It is a key component in time-release coatings used in some medications. Neither the liquid nor powdered form contains significant amounts of vitamins or minerals, and all of its carbs and calories come from fiber. However, some pectin dry mixes may contain added sugar and calories.
