What is pectin?
Pectin is a “gum” found naturally in fruits that causes jelly to gel. Tart apples, crab apples, sour plums, Concord grapes, quinces, gooseberries, red currants and cranberries are especially high in pectin. Apricots, blueberries, cherries, peaches, pineapple, rhubarb and strawberries are low in pectin. Underripe fruit has more pectin than fully ripe fruit. Jellies and jams made without added pectin should use 1/4 underripe fruit. Many recipes call for the addition of pectin. Pectin is available commercially either in powdered or liquid form. These two forms are not interchangeable, so use the type specified in the recipe. Powdered pectin is mixed with the unheated fruit or juice. Liquid pectin is added to the cooked fruit and sugar mixture immediately after it is removed from the heat. When making jellies or jams with added pectin, use fully-ripe fruit. Pectin is concentrated in the skins and cores of fruit; that is why some recipes call for those to be included. Commercial pectins may

Structure Galacturonic Acid Unit Pectin for use in food is defined as a polymer containing galacturonic acid units (at least 65%). The acid groups may either be free, combined as a methyl ester, or as sodium, potassium, calcium or ammonium salts, and in some pectins amide groups may also be present. 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. Plant cell wall structure diagram Pectin in this state contains a range of neutral sugar molecules, in a complex non-random structure, containing blocks of homogalacturonic acid (sometimes called “smooth regions”), and blocks containing many neutral sugar molecules (rhamnose, galactose, arabinose, and lesser amounts of other sugars) in a highly branched structure (sometimes referred to as “hairy regions”). Plant Wall Cell Structure When pectin is extracted, much of the hairy r
Pectin refers to a group of diverse and complex polysaccharides found in the primary cell wall and intercellular space (middle lamella) of plant cells. Pectin is mostly composed of a sugar residue called D-galacturonic acid. The dominant polysaccharides in pectin are homogalacturonan, rhamnogalacturonan I, rhamnogalacturonan II, and xylogalacturonan. Pectin is a carbohydrate.
Pectin is a natural soluble fiber extracted from apples and citrus fruits and is commonly used as a thickener in jellies and jams.

Quercetin, a highly potent anti-oxidant flavonoid, is extracted from fruits and vegetables.

What is Bromelain? Bromelain is a natural digestive agent, extracted from pineapples, which causes the body to absorb far more vitamins & minerals from ingested nutrients than without it. Bromelain has many other benefits. Click here to read about how bromelain acts as an anti-in
