Pectin vs. Gelatin

By Jaxson

Main Difference

The main difference between Pectin and Gelatin is that the Pectin is a structural heteropolysaccharide contained in the primary cell walls of terrestrial plants and some algae and Gelatin is a mixture of peptides and proteins derived from connective tissues of animals.

  • Pectin

    Pectin (from Ancient Greek: πηκτικός pēktikós, “congealed, curdled”) is a structural heteropolysaccharide contained in the primary cell walls of terrestrial plants. It was first isolated and described in 1825 by Henri Braconnot. It is produced commercially as a white to light brown powder, mainly extracted from citrus fruits, and is used in food as a gelling agent, particularly in jams and jellies. It is also used in dessert fillings, medicines, sweets, as a stabilizer in fruit juices and milk drinks, and as a source of dietary fiber.

  • Gelatin

    Gelatin or gelatine (from Latin: gelatus meaning “stiff”, “frozen”) is a translucent, colorless, brittle (when dry), flavorless food ingredient that is derived from collagen obtained from various animal body parts. It is commonly used as a gelling agent in food, medications, drug and vitamin capsules, photographic films and papers, and cosmetics.

    Substances containing gelatin or functioning in a similar way are called “gelatinous”. Gelatin is an irreversibly hydrolyzed form of collagen, wherein the hydrolysis results in the reduction of protein fibrils into smaller peptides, which will have broad molecular weight ranges associated with physical and chemical methods of denaturation, based on the process of hydrolysis. It is found in most gummy candy, as well as other products such as marshmallows, gelatin desserts, and some ice creams, dips, and yogurts. Gelatin for recipe use comes in the form of powder, granules, or sheets. Instant types can be added to the food as they are; others need to be soaked in water beforehand.

  • Pectin (noun)

    A jellies and jams where it causes thickening (setting).

    “Apple is rich in pectin and so is often added to other fruits when making jam so it will set.”

  • Gelatin (noun)

    A protein derived through partial hydrolysis of the collagen extracted from animal skin, bones, cartilage, ligaments, etc.

  • Gelatin (noun)

    An edible jelly made from this material.

  • Gelatin (noun)

    A thin, translucent membrane used as a filter for photography or for theatrical lighting effects.
