Stevia Extract

[Characteristics]

Stevia sugar features high sweetness and low calorie and its sweetness is 200 350  times of that  of cane sugar but its calorie is only 1/300 of that of cane sugar.

The component of stevia extract that gives it its sweetness is a mixture of various steviol glycosides. The components of sweetness in stevia leaves are stevioside, rebaudioside A, C, D, E and dulcoside A. Rebaudioside C, D, E and dulcoside A are small in quantity. The principal components are stevioside and rebaudioside A.

The quality of stevioside and rebaudiosideA is better than those of other components, which are commercially extracted and used in various applications.

The steviol glycosides present in stevia extract are referred to as “steviosides” or ¡°stevia extract¡±. Among these “steviosides”, the most common is Stevioside followed by RebaudiosideA. The Stevioside has a slight and pleasant herbal taste and the Rebaudioside-A has no herbal taste.

Although Rebaudioside C and dulcoside A are small in quantity in stevia extract, they are the major components giving bitter aftertaste.

[Function]

A large number of pharmaceutical tests have proved that stevia sugar has no side effects, carcinogens, and is safe for eating.

Compared with cane sugar, it can save 70% of the cost. With pure white color, pleasing taste and no peculiar smell, Stevia sugar is a new sugar source with broad perspective for development. Stevia rebaudianum sugar is the natural low hotsweet agent mostly similar to the flavor of cane sugar, approved to be used by State Ministry of Health and Ministry of Light Industry.

It is the third natural succedaneum of cane sugar and beet sugar with development and health care value, extracted from the leaves of the herbal vegetable of the composite family-stevia rebaudianum.

Description

Carbohydrates
There are two types of carbohydrates:
The simple sugars
Glucose, sucrose, fructose (and many others)
The complex carbohydrates.
Carbohydrates that are made of long chains of sugars
Starches, cellulose

Simple Sugars
All carbohydrates are made up of units of sugar (also called saccharide units).
Carbohydrates that contain only one sugar unit are called monosaccharides.
Glucose
Fructose
Simple Sugars
Disaccharides have two sugar units bonded together.
For example, common table sugar is sucrose (below), a disaccharide that consists of a glucose unit bonded to a fructose unit.

Complex Carbohydrates
Complex carbohydrates are polymers of the simple sugars.
In other words, the complex carbohydrates are long chains of simple sugar units bonded together.
For this reason the complex carbohydrates are often referred to as polysaccharides.
Complex Carbohydrates
Starch (below) is a polymer of the monosaccharide glucose (n is the number of repeating glucose units and ranges in the 1,000′s).
Starches and cellulose are complex carbohydrates used by plants for energy storage and structural integrity.
Complex Carbohydrates
Glycogen, another polymer of glucose, is the polysaccharide used by animals to store energy.
Both starch and glycogen are polymers of glucose.
Starch is a long, straight chain of glucose units, whereas glycogen is a branched chain of glucose units.

Proteins
Proteins are polymers of amino acids.
Amino acids all have the general structure:
The R in the diagram represents a functional group that varies depending on the specific amino acid in question.
Twenty amino acids in human metabolism
Proteins
When 2 amino acids bond together, water is released as the carboxyl end of one amino acid bonds to the amine end of the adjacent one forming a peptide bond, as illustrated at the left.
Because water is lost, the process is called:
Condensation synthesis, or…
Condensation polymerization
Proteins
When many amino acids bond together to create long chains, the structure is called a protein (it is also called a polypeptide because it contains many peptide bonds).
Proteins
Proteins are large molecules that may consist of hundreds, or even thousands of amino acids.
While there are hundreds of thousands of different proteins that exist in nature, they are all made up of different combinations of amino acids.

Fats
Fats are a sub-group of compounds known as lipids that are found in the body and have the general property of being hydrophobic (meaning they are insoluble in water).
Other lipids include waxes, and steroids, such as cholesterol.
Fats
Fats are also known as triglycerides, molecules made from the combination of one molecule of glycerol with three fatty acids.
Glycerol
Fatty
acids
Triglyceride
“R” is a long chain of carbon and hydrogen
Fats
The type of fatty acid in the molecule determines the type of fat:
Saturated fats
All single bonds in the carbon chain
Solids at room temperature
Mono-unsaturated fats
One double bond in the carbon chain, the remainder single
Liquids at room temperature
Polyunsaturated fats
Two or more double bonds in the carbon chain
Liquids at room temperature
