CAS NO. 57-48-7

Fructo-oligosaccharide is a new healthy sugar source.Its structure can be expressed as GF-Fn,(n=1-9). Fructooligosaccharide (FOS) is a food ingredient naturally occurring in honey, fruits and plants. It is a natural soluble vegetable fiber with a low caloric value and patient-friendly. It has the function of cleaning intestines, good multiplication effect of beneficial bacteria, enhancing immunity.
The physical and chemical character of FOS
FOS is fermented by the colonicmicroflora. It promotes the growth of Bifidobacteria, improves the composition of the intestinal flora and decreases the blood cholesterol content. FOS can be a dietary supplement, it is widely used in yogurt, bakery, functional and dietetic food, pills, liquors and etc..
The application scope of FOS
Its modifying property adds rheological and textural properties to food. It is used as a sugar replacement, dietary supplement or food additives in the food production and dietetic product industry. It can used in beverage, dairy product, candy, dessert and other fields.

Fructose-oligosaccharides(FOS) is a mixture of oligosaccharides (GF2, GF3, GF4) which are composed of fructose units connected by ß (2-1) links. These molecules are terminated by a fructose unit. The total number of fructose or glucose units (Degree of Polymerization or DP) of oligofructose ranges mainly between 2 and 4.
Fructose-oligosaccharides(FOS), is also know as Fructo-oligo, it directly enters into large intestine without being digested and absorbed by human body, and in intestine it rapidly promotes reproduction of bididobactirium and other probiotics, so it is also called "Bifidus Factor".

In China,MOH'S No.11 Announcement of 2009 authorize FOS as a new nutritional fortifiers.
NO.6 Announcement of 2012 authorize FOS source from sucrose, suppiemented as nutrition fortifier.
In Japan, authorize FOS as specific health food.
In USA, FDA validate FOS as a safe class(GRAS) of food ingredient.

*sweetness: 0.3-0.6 times of sucrose
*low calorie: 1.5Kcal/g calories
*solubility: Soluble in water and more soluble than sucrose
*viscosity: Viscosity is relativity higher than sucrose
*function: FOS can promote the increment of bifidobacterium ,prevent geting inflamed, improve bowel function, enhance immunity and disease resistance, reduce the incidence of oral cavity ulcer, promote the absorption of minerals for human body, prevent constipation, prevent dental caries, hairdressing, reduce blood fat, etc.

Food Additives Crystalline Fructose (C6H12O6) (CAS: 57-48-7)Product Description

Crystalline fructose is a processed sweetener derived from corn that is almost entirely fructose. It can also be made from sucrose (table sugar) by splitting the fructose and glucose molecules. Crystalline fructose consists of at least 98% pure fructose, any remainder being water and trace minerals. It is used as a sweetener in the likes of beverages and yogurts, where it substitutes for high-fructose corn syrup (HFCS) and table sugar. Crystalline fructose is estimated to be about 20 percent sweeter than table sugar,[1] and 5% sweeter than HFCS.
CHARACTERISTICS Fructose is white crystallized powder,sweet taste, tasting twice as sweet as sucrose,and tastes particularly sweet when cold or in solution,it is sweetest glucide.

See also: Production of high-fructose corn syrup
Crystalline fructose is created from cornstarch, but other starches such as rice and wheat can be used. In this method, corn is first milled to produce cornstarch, then processed to yield corn syrup which is almost entirely glucose. The glucose obtained is reacted with a series of enzymes to convert nearly all the glucose into fructose. The fructose is then allowed to crystallize out, and is finally dried and milled to produce crystalline fructose.

Application :
Food Industry :
Fructose replaces sucrose in canned fruit and fruit preserves together with 20-30% maltose syrup, also it is can be used in carbonated beverages as only sweetener or in combination sucrose and with artificial sweeter such as saccharin.

Other applications :
Bread and cakes,Creams,Marmalade,Chocolate,Soft drinks,etc.

Health effects
There are studies for and against the health benefits of crystalline fructose.
Crystalline fructose is generally considered safe, but concerns have been raised about health effects, particularly hepatotoxicity. As of January 2010, the FDA has not designated crystalline fructose to be generally recognized as safe.
Because crystalline fructose is sweeter than the sugars it replaces, less sugar can be used to produce a desired level of sweetness, resulting in a roughly 5-percent reduction in the amount of calories. Fructose is also an isomer of glucose, carrying the same energetic value when burned.
Any positive health benefit of crystalline fructose consumption is fueled primarily by the fact that fructose does have the same value as glucose when burned. However, fructose is processed by the body differently; fructose's causal relationship to hyperlipidemia, fatty liver disease, cirrhosis, coronary arterial disease and obesity remain a concern for public health analysts.
