Stevia history:

Stevia is a 0 Cal natural sweetener and is rapidly gaining acceptance as the only natural product with the capacity to achieve scale in reducing the sugar or calorie content in mainstream food and drinks yet maintaining their desired sweet taste. Stevia has been used as a sweetener for several hundred years originally by the Paraguay Indians. It has been tested extensively by food and drug regulatory authorities and is registered for sale as a sweetener in almost all major markets globally. Stevia is also sustainable sweetening ingredient and it is a plant extract that has been used as a natural sugar substitute in parts of the globe for centuries.

Stevia main features:

1) 0 Cal.
2) Naturally sourced sweetener(plant extract, not an artificial sweetener)
3) Manage people blood sugar (no effect on insulin levels)
4) High intensity sweetener (200-350 times sweeter than sucrose)

Sunresin resin technology boosts stevia to large-scale industrialization:

Sunresin has been engaged in the research and development of resin products for nearly 20 years. Based on resin technology, combined with system engineering integration and automation development, Sunresin has developed into a globally influential resin and integrated equipment service provider. In the field of stevia, after years of research and development, we have successfully launched a series of resins with excellent performance, which are widely used in mainstream stevia factories in the world. At the same time, Sunresin designed a complete production line of stevia, which can provide customers with EPC services from dry stevia leaves to finished stevia powder(TSG90/95).The stevia production line uses the most advanced continuous ion exchange resin system (SMB), which greatly reduces consumption of water, solvents, etc., and waste water discharge.

The following services can be obtained from Sunresin depends on needs:

Option 1: The top quality resin
Option 2: Resin purification unit (resin + process technology + system equipment etc.)
Option 3: EPC line - the whole solution package
(resin + process technology + whole line design + whole line equipment supply+ commissioning service etc.)

The following services can be obtained from Sunresin depends on needs:

Process	Resin Code	Application
Adsorbed process	LXS868	High selecvity and adsorption capacity for Stevia glycoside. After elution, TSG in elution liquor could reach 84-88%(depending on raw materials).
Ion exchange resin (desalination and decolorization)	LXS861 LXS865	1.Remove Ca2+ ,Mg2+ and other metal ions, remove the ash
		2.Reduce the liquor PH for better decolor
		3.Remove tiny amount of cation pigments
		4.Superior performance to remove rough color impurities
Resin refining	LXS869	Remove substance like Steviol, stevidin and flavonoids or polyphenols, increase purity for extra 2-5%, also it removes bitterness for better taste.

Flowchart of the main process:

Advantages of using Sunresin resin or solution package:

1) Lower loss during the operation with higher yield
2) Greatly simple the process of extracting stevia glucosides
3) Much lower operation cost due to less consumption of water, solvents and waste discharge
4) High purity and tasteful product could be achieved compared with other methods
5) Holding the key know-how of best stevia purification process and resins in the world
6) Proven & mature technology and widely used by other leading producers in industry
7) Abundant experience in delivering EPC plants in China and overseas
