High Quality Supplement Raw Material D-Fructose CAS 57-48-7 White Powder with Best Price in Stock
Product Description-------------------------------------------------------------------------------------------------------
D-Fructose is present as a monosaccharide in fruits and vegetables, as a disaccharide in sucrose (with D-glucose), and as oligoand polysaccharides (fructans) in many plants. It is also used as an added sweetener for food and drink, and as an excipient in pharmaceutical preparations, syrups, and solutions.
In equal amounts, it is sweeter than glucose or sucrose and is therefore commonly used as a bulk sweetener. An increase in high fructose corn syrup, as well as total fructose, consumption over the past 10 to 20 years has been linked to a rise in obesity and metabolic disorders. This raises concerns regarding the short and long-term effects of fructose in humans.
Fructose is present more or less frequently than glucose in the juices of plants, fruits, and especially the honey, which is about half the solid matters. It leads to an equal amount of glucose by the hydrolysis of sugar cane and a smaller proportion than some other less common sugars. It is used, such as glucose, in the production of glycogen. It enters the body through either be eaten as such or as the result of digestion of sugar cane. It is mainly changed into glycogen or triglycerides after reaching the liver, so do not enter largely in the blood circulation. Glucose and fructose are partially inter-convertible under the influence of very dilute alkali. It is not surprising; therefore, that fructose must be converted to glycogen in the liver, which on hydrolysis yields of glucose. Dubois et al. reported that regular consumption of sugary drinks between meals increases risk of overweight among preschool children.
Fructose has been claimed to be of concern due to several factors: First, in the 1980's, sucrose was replaced to a large extent, particularly in North America, by high fructose corn syrup (HFCS) in carbonated beverages. The intake of soft drinks containing HFCS has risen in parallel with the epidemic of obesity[7]. Second, dietary fructose has been implicated in risk factors for cardiovascular disease (CVD): 1. Plasma triglycerides (TG) and VLDL-TG increased following the ingestion of large quantities of fructose; 2. Fructose intake has been found to predict LDL particle size in overweight schoolchildren. 3. A positive relationship has been demonstrated between fructose intake and uric acid levels[9]. Third, the use of fructose as a sweetener has increased. The third National Health Examination Survey (NHANES) demonstrated that over 10% of Americans' daily calories were from fructose. These studies suggest that the relationship between fructose and health needs re-evaluation.

Application
1. D-Fructose occurs in a large number of fruits, honey, and as the sole sugar in bull and human semen
2. Fructose is a naturally occurring sugar in fruits and honey. It has moisture-binding and skin-softening properties.
3.Fructose is a sweetener that is a monosaccharide found naturally in fresh fruit and honey. It is obtained by the inversion of sucrose by means of the enzyme invertase and by the isomerization of corn syrup. It is 130-180 in sweetness range as compared to sucrose at 100 and is very water soluble. It is used in baked goods because it reacts with amino acids to produce a browning reaction. It is used as a nutritive sweetener in low-calorie beverages. It is also termed levulose and fruit sugar.
