Pectin E number is E440

Pectin is used in food as a gelling agent particularly in jams and jellies. Pectin is present not only throughout primary cell walls but also in the middle lamella between plant cells where it helps to bind cells together. Pectin is a natural part of human diet, but does not contribute significantly to nutrition.
Some plants such as sugar beet, potatoes and pears contain pectins with acetylated galacturonic acid in addition to methyl esters. Most pectin you buy at the supermarket is produced in Europe and imported to the U.S. Pectin is easy and convenient to use with soft fruits which have a low to medium pectin content such as strawberries.
Pectin E number is E440 is a complex carbohydrate, which is found both in the cell walls of plants, and between the cell walls, helping to regulate the flow of water in between cells and keeping them rigid. Pectin for use in food is defined as a polymer containing galacturonic acid units . Pectin in the plant starting material is part of a very complex structure, which gives shape to the soft non-woody parts of the plant.
Food additives are used to enhance the taste, texture, shelf life and nutritional properties of food. Food additives are substances added to foods with a specific technical purpose and are classified depending on the function performed, for example, stabilizers, thickeners, gelling agents.
