Pectic substances are complex carbohydrates found in the cell walls of plants. They're especially abundant in fruits and vegetables, contributing to their structure and firmness. Think of them as the 'glue' that holds plant cells together. When heated with sugar and acid, they form a gel, which is why they're crucial in making jams and jellies. Pectin makes your homemade jam set properly. It gives processed foods a desired texture.
