What Is Pectin E440?

Pectin definition

Pectin E440 is defined as a polymer containing galacturonic acid units (at least 65%). The acid groups commonly combines with methanol as a methyl ester, or combines with sodium, potassium, calcium or ammonium as salts, and amide groups may also be present in some pectins. Pectin E440 is a white to light brown powder, extracted from fruits used in food as a gelling agent, thickener, stabilizer in jams, jellies, dessert fillings, fruit juices and milk drinks and so on. As a apple and citrus peel Pectin manufacturer & supplier in China, we would like to give you more information about Pectin from our understanding.

Pectin in plant

Pectin is a natural component located in the plant cell walls. Natural pectin substances are a component of the cell wall. They are present along with cellulose and constitute an adjoining layer in the middle of the cell, allowing the cells of the plant tissue to bind tightly together.

Natural pectin substances are widely present in the fruits, roots, stems and leaves of plants in the form of protopectin, pectin and pectic acid.

Pectin is a linear polysaccharide polymer containing from several hundred to about 1000 anhydrogalluronic acid residues with a corresponding average relative molecular weight of 50,000 to 150,000.

Pectin is a soluble dietary fibre, Part of galluronic acids are present as methyl ester.

Pectin is obtained by aqueous extraction of the appropriate edible plant materials, mainly from citrus peel or apple pomace, followed by a selective precipitation using alcohol or salts.

What does pectin E440 do?

In plant, Natural Pectin is playing a control the flow of fluid in the important role of water and plants.

In food, Pectin is used as a gelling agent, thickener or stabilizer. Sometimes it is called gelling agent pectin, gelling agent fruit pectin or pectin stabilizer.

Where does pectin E440 come from?

Pectin is mainly extracted from citrus fruits and vegetables. Pectin amount in fruits varies from the type of fruit. The major raw material used for the production of industrial product is apple and dried citrus peel which is available in white and light brown powder commercially.

Which fruit contains high/low pectin E440?

High pectin fruits: lime, lemon, orange, and apple.

Average pectin fruits: apricot and blackberry.

Low pectin fruits: cherry, peach, and pineapple.

In the citrus fruits (orange, lemon, and lime), pectin is mainly located in the albedo, the inner white layer of the peel that surrounds the juicy vesicles, and the lamellae. When the juice is extracted from the fruit, the peel and the albedo can be used to make the pectin.
