Health Benefits:

 It is a white to off white crystalline powder, widely found in the vegetables, fruits, and
grains, are chemically similar to cholesterol. Phytosterols that in modest amounts cam
lower cholesterol and show anticancer activity in lab an animal studies.

  Phytosterols are responsible for the cholesterol-lowing properties of mono-and
polyunsaturated oils. Some key sterols that lower cholesterol are beta-sitosterol,
campesterol, stigmasterol and brassicasterol.

 Application:

As antioxidant in food and feed additives

As aliments and moisturizer for skin in cosmetics

As raw material of steroidal medicine and vitamin D3

 

 

  Phytosterols, which encompass plant sterols and stanols, are steroid compounds similar to

cholesterol which occur in plants and vary only in carbon side chains and/or presence or

absence of a double bond. Stanols are saturated sterols, having no double bonds in the

sterol ring structure. More than 200 sterols and related compounds have been identified.

Free phytosterols extracted from oils are insoluble in water, relatively insoluble in oil,

and soluble in alcohols.

  Phytosterol-enriched foods and dietary supplements have been marketed for decades.

Despite well documented LDL cholesterol lowering effects, no scientifically proven evidence

of any beneficial effect on cardiovascular disease (CVD) or overall mortality exists.


  The richest naturally occurring sources of phytosterols are vegetable oils and products

made from them. They can be present in the free form and as esters of fatty acid/cinnamic

acid or as glycosides, respectively. The bound form is usually hydrolyzed in the small

intestines by pancreatic enzymes. Nuts, which are rich in phytosterols, are often eaten in

smaller amounts, but can still significantly contribute to total phytosterol intake. Cereal

products, vegetables, fruit and berries, which are not as rich in phytosterols, may also be

significant sources of phytosterols due to their higher intakes. The intake of naturally

occurring phytosterols ranges between ~150–450 mg/day depending on eating habits.

Specially designed vegetarian experimental diets have been produced yielding upwards of 700

mg/day. The most commonly occurring phytosterols in the human diet are β-sitosterol,

campesterol and stigmasterol, which account for about 65%, 30% and 3% of diet contents,

respectively. The most common plant stanols in the human diet are sitostanol and

campestanol, which combined make up about 5% of dietary phytosterol.
