Consumption
of pectin may reduce blood cholesterol levels :
Pectin is a natural part of the
human diet with no contribution to nutrition as such. Assuming our consumption of
fruits and vegetables is 500 grams per day, the daily intake of pectin can be
estimated to be around 5. In human digestion, pectin binds to cholesterol
in the gastrointestinal tract and slows glucose absorption by trapping
carbohydrates. Pectin is a soluble dietary fiber.
Consumption
of pectin has been shown to reduce blood cholesterol levels. The mechanism
appears to be an increase of viscosity in the intestinal tract, leading to a
reduced absorption of cholesterol from bile or food.[3] In
the large intestine and colon, microorganisms degrade pectin and liberate
short-chain fatty acids that have positive influence on health (prebiotic effect).[citation needed]
Apples, guavas, quince, plums, gooseberries, oranges and
other citrus fruits,
contain large amounts of pectin, while soft fruits like cherries, grapes and strawberries contain
small amounts of pectin.
Typical levels of pectin in
plants are (fresh weight):
·
apples, 1–1.5%
·
apricot, 1%
·
cherries, 0.4%
·
oranges, 0.5–3.5%
·
carrots approx.
1.4%
·
citrus
peels, 30%
The main raw-materials for pectin
production are dried citrus peel or apple pomace, both by-products of juice production.
Pomace from sugar-beet is also used to a small extent.
