Steviose
In 1931, two French scientists, M. Bridel and R Lavielle
isolated the glycosides that give stevia its sweet taste

                                                           These glycosides were named
                                                           stevioside and rebaudioside.

                                                                          R2

      These compounds are 250–300 times sweeter than ordinary table sugar.
In terms of weight fraction, the four major steviol glycosides
                                    found in the Stevia plant tissue are:

Now, commercial
cultivation of Stevia is
  practiced in many
       countries
Today, stevia is cultivated and used in China, Korea, Taiwan, Thailand, Malaysia
          and part of South America (Brazil, Paraguay, and Uruguay)
By 1977 the Maruzen Kasei Co., Ltd. started extracting
     Stevioside on a commercial basis in Japan.

Japan currently consumes more stevioside than any other
country; there, stevioside products accounts for 40% of the
                     sweetener market.
At present, Diet Coca Cola is
sweetened by Stevioside in Japan
Stevioside is now available in different dilutions
(97% to 1%) both in bulk and in retail quantities.
Steviose
Pure Stevioside is too intensely sweet to
 be used directly for sweetening anything.




A diluted preparation (1-2%) can be safely used
for sweetening hot beverages like tea or coffee
Since Stevioside is fairly thermostable, it can
      be used all types of bakery and
          confectionary products.

Use of stevioside lowers the calorie content
of these foods and makes it suitable for the
        diabetics and dieting people
Stevioside is very much
 compatible with frozen dairy
          products.

Low calorie natural Ice-cream,
 mousses and shakes can be
  prepared with stevioside
Indian sweets base on dairy, cereal and legume products can be sweetened
by Steviosides to make those suitable for diabetics and health conscious
persons.

Stevioside does not impart any unacceptable taste or smell to such food
items. It is also compatible with all types of added flavours and colours
Stevioside is most suitable for
Indian     cooking  as    it   is
thermostable, compatible with all
spices, does not caramelize and
does not impart any colour or
flavour of its own.
Stevioside may also be an excellent
sweetener for the protein health drinks
for sports persons.
Apart from sweetening, Steviosides
also exerts cardio-tonic and anti-
oxidant effects which is an absolute
necessity in endurance sports.
Stevioside Can be used a sweetening agent for many
pharmaceutical preparations, to make them suitable for
diabetic and dieting patients. It is compatible with most of
the ingredients used in OTC medicines. It can be used in
oral liquids as well in chewable tablets.
Research clearly shows that Streptococcus mutans,
Pseudomonas aeruginos, Proteus vulgaris and other
microbes do not thrive in the presence of the
nonnutritive stevia constituents. This fact, combined
with the naturally sweet flavor of stevioside, makes
it a suitable ingredient for mouthwashes and
toothpastes.

Obesity in the developing world can be
viewed as a result of a series of changes
in diet, physical activity, health and
nutrition.
The health, economic and psychosocial
consequences      of    the    increasing
incidence of obesity are substantial.
Obesity is associated with numerous
health complications, which range from
non-fatal debilitating conditions such as
osteoarthritis, to life threatening chronic
diseases such as Coronary Heart
Disease, diabetes, and certain cancers.
Use of stevioside may be a very important tool for nutritional
management by lowering carbohydrate intake, specially
intake of ―Empty Calories‖ through refined sugar.
Thus, stevioside offers a ―Natural‖ solution for food intake
related obesity.




                       Is equivalent to


                                          1g Stevioside

Extracts of leaves from the plant Stevia
rebaudiana have been used in the
traditional treatment of diabetes in
Paraguay and Brazil.
In recent studies, anti-diabetic effect of
stevioside is proved beyond doubt.

Dental caries (tooth decay) is a common consequence of common sugar
consumption, because sugar forms a sticky coat on the teeth, which harbours many
bacteria responsible tooth decay




Stevioside does not help to form such sticky plaque on teeth. It also help to prevent
dental cavities by inhibiting the bacteria Streptococcus mutans that stimulates
plaque formation.

Steviosides was found to
         have immuno-stimulant and
         anti inflammatory effects.
         Steviosides actually blocks
         pro-inflammatory cytokines
         and thus directly reduces
         inflammation.

Stevia     contains     antiseptic
properties which have proven
beneficial in speeding the
healing process of skin wounds.


Tests     show      that  stevia’s
antimicrobial properties inhibit
the growth of streptococcus and
other bacteria. This is especially
noteworthy since some forms of
streptococcus have become
antibiotic resistant.
Guarani Indians and other people who have
become familiar with stevia report that it is
effective when applied to acne, seborrhea,
dermatitis, eczema, etc. Placed directly in
cuts and wounds, more rapid healing,
without scarring, is observed.



In later researches, it was found that
stevioside and its metabolic products
isoteviol and steviol, block glucose entry
into said sebaceous cells thereby inhibiting
production of sebum, which, in turn,
diminishes the chance of acne formation.

Stevioside or steviol, at 0-200 micromoles, was incubated with human breast (MCF-7),
colon (Caco-2), and prostatic (DU 145) cancer cells for 24 h.
Results showed that
    Stevioside and steviol significantly reduced the migration of Caco-2 and MCF-7 cells
    Steviol caused cancer cell death by apoptosis
    Steviol reduced HIF-1 alpha protein level and DNA binding (v)
     Steviol was effective against DU 145 proliferation
     Stevioside was effective against all cancer cells

WHO Food Additives, 1999. Series 42: Safety evaluation of certain food additives
’’Stevioside’’, Genf, pp. 119–143.




              Stevia products has
              thousands of years of
              history of use without
              any report on its’
              adverse effects
Stevioside, is an absolutely

                     Natural product
                             with

     No chemical modification after extraction.
Its safety has been established by scientific studies as well as
its continuous use for thousands of years.



Now, let us have a look at the safety records of other popular
zero calorie sweeteners – Aspertame and Sucralose – which are
synthetic chemicals.
Aspertame, one of the popular artificial zero calorie sweetener is
actually a potentially hazardous substance.

        Reported Adverse Effects of Aspertame

        Brain tumors                         Multiple sclerosis
        Lymphoma                             Attention Deficit Disorder
        Arthritis                            Chronic faigue syndrome

US Air Force acknowledge that ingestion of aspartame make pilots more
susceptible to seizures and vertigo and issued a safety alert to its pilots

Services Memorandum, April 1, 1993, Reprinted in preface of "Bittersweet Aspartame: A Diet Delusion" by
Barbara Alexander Mullarkey, NutriVoice, P.O. Box 946, Oak Park, Illinois 60303, (708) 848-0116.
The other alternative, Sucralose – which is actually a chlorinated
  hydrocarbon like some pesticides – is also not free from adverse effects.

   The adverse effects encountered in the pre-approval research include –

          Shrunken thymus glands (up to 40% shrinkage)

          Atrophy of lymph follicles in the spleen and thymus

          Extension of the pregnancy period and aborted pregnancy

          Decreased foetal body weights and placental weights

Steviose
The Joint Expert Committee of The World Health
Organisation and the Food and Agriculture Organisation of
the United Nations allowed an Average Daily Intake (ADI) of
2mg/Kg body weight in 2004

They prepared the standard specification of Stevioside in 68th
JECFA meting which was published in             FAO JECFA
Monographs 4 (2007) in included in the Codex Alimentarius.

 In the 69th JECFA held at Rome in June, 2008, the
 allowable ADI was increased to 4 mg steviol /Kg
 bodyweight for human consumption

 Their recommendation was based on long term exposure
 study with 970mg stevioside/Kg body weight which is
 equivalent to 383 mg/Kg Steviol and they have considered
 a safety factor of 100
Two US companies Merisant and Cargill notified USFDA that
Stevioside should have GRAS status and submitted evidence
that it is safe to use in food.


The USFDA concluded in December 2008 that it has no
objection to 95% pure stevioside to have GRAS status for
food and drink



US Pharmacopeia has developed set of reference standards for
stevia based sweetners (written FCC testing standard is expected
to be released in August, 2009) for a ―rapid and unbiased decision‖
for quality checks to ensure safety of consumers.
Coca Cola partnered with Cargill to develop their
           stevioside brand ―Truvia‖
Coca cola now sweeten their
―Sprite Green‖ and ―Odwalla‖
Juice Drink with Stevioside
Pepsico partnered with Whole Earth Sweetener
Co. (a subsidiary of Merisant) and Pure Circle to
develop their ―Purevia‖ brand
Pepsico planned to sweeten their ―SoBe Lifewater‖ brand
soft drinks with Stevioside

  • 2. S Strong T Toned-up E Energetic The Wonder Herb V Vigorous I Immune A Active
  • 4. In 1931, two French scientists, M. Bridel and R Lavielle isolated the glycosides that give stevia its sweet taste These glycosides were named stevioside and rebaudioside. R2 O H 3C CH2 H H 3C H CO O R1 These compounds are 250–300 times sweeter than ordinary table sugar.
  • 5. In terms of weight fraction, the four major steviol glycosides found in the Stevia plant tissue are: Glc-(2-1)-Glc Glc-(3-1)-Glc-(2-1)-Glc Glc-(3-1)-Glc-(2-1)-Rha Glc-(2-1)-Rha O O O O H3C CH2 H3C CH2 H3C CH2 H3C CH2 H H H H H3C H H3C H H3C H H3C H CO CO CO CO O O O O Glc Glc Glc Glc 5–10% 2–4% 1–2% 0.5–1% Stevioside Rebaudioside A Rebaudioside C Dulcoside A
  • 6. R2 O H3C CH2 Steviosides are white to pale H yellow coloured crystals with a H3C CO H faint herbal smell. O It has no calories and does not R1 induce glycemic response. It is completely soluble in water and water solution is clear. Pure stevioside is hygroscopic (absorbs moisture from air)
  • 7. Stevioside shows very good thermal stability. Incubation of solid stevioside at elevated temperatures for one hour showed good stability up to 120oC. R2 O H3C CH2 In aqueous solution stevioside was remarkably stable in a pH range of 2-10 under thermal treatment H up to 80oC. H 3C H CO O R1
  • 9. Now, commercial cultivation of Stevia is practiced in many countries
  • 10. Today, stevia is cultivated and used in China, Korea, Taiwan, Thailand, Malaysia and part of South America (Brazil, Paraguay, and Uruguay)
  • 11. By 1977 the Maruzen Kasei Co., Ltd. started extracting Stevioside on a commercial basis in Japan. Japan currently consumes more stevioside than any other country; there, stevioside products accounts for 40% of the sweetener market.
  • 12. At present, Diet Coca Cola is sweetened by Stevioside in Japan
  • 13. Stevioside is now available in different dilutions (97% to 1%) both in bulk and in retail quantities.
  • 15. Pure Stevioside is too intensely sweet to be used directly for sweetening anything. A diluted preparation (1-2%) can be safely used for sweetening hot beverages like tea or coffee
  • 16. Since Stevioside is fairly thermostable, it can be used all types of bakery and confectionary products. Use of stevioside lowers the calorie content of these foods and makes it suitable for the diabetics and dieting people
  • 17. Stevioside is very much compatible with frozen dairy products. Low calorie natural Ice-cream, mousses and shakes can be prepared with stevioside
  • 18. Indian sweets base on dairy, cereal and legume products can be sweetened by Steviosides to make those suitable for diabetics and health conscious persons. Stevioside does not impart any unacceptable taste or smell to such food items. It is also compatible with all types of added flavours and colours
  • 19. Stevioside is most suitable for Indian cooking as it is thermostable, compatible with all spices, does not caramelize and does not impart any colour or flavour of its own.
  • 20. Stevioside may also be an excellent sweetener for the protein health drinks for sports persons. Apart from sweetening, Steviosides also exerts cardio-tonic and anti- oxidant effects which is an absolute necessity in endurance sports.
  • 21. Stevioside Can be used a sweetening agent for many pharmaceutical preparations, to make them suitable for diabetic and dieting patients. It is compatible with most of the ingredients used in OTC medicines. It can be used in oral liquids as well in chewable tablets.
  • 22. Research clearly shows that Streptococcus mutans, Pseudomonas aeruginos, Proteus vulgaris and other microbes do not thrive in the presence of the nonnutritive stevia constituents. This fact, combined with the naturally sweet flavor of stevioside, makes it a suitable ingredient for mouthwashes and toothpastes.
  • 24. Obesity in the developing world can be viewed as a result of a series of changes in diet, physical activity, health and nutrition. The health, economic and psychosocial consequences of the increasing incidence of obesity are substantial. Obesity is associated with numerous health complications, which range from non-fatal debilitating conditions such as osteoarthritis, to life threatening chronic diseases such as Coronary Heart Disease, diabetes, and certain cancers.
  • 25. Use of stevioside may be a very important tool for nutritional management by lowering carbohydrate intake, specially intake of ―Empty Calories‖ through refined sugar. Thus, stevioside offers a ―Natural‖ solution for food intake related obesity. Is equivalent to 1g Stevioside 250g sugar No Calories 1040 Calories
  • 26. Extracts of leaves from the plant Stevia rebaudiana have been used in the traditional treatment of diabetes in Paraguay and Brazil. In recent studies, anti-diabetic effect of stevioside is proved beyond doubt. Steviosides Improves glucose tolerance Enhances insulin secretion Reduces glycogen breaking hormones
  • 27. In pancreas, there are some specilised cells ( -cells) which secrete Insulin In some type of diabetes, Insulin secretion from these cells is diminished In some research work in Aarhus University Hospital, Stevioside Denmark and elsewhere, it was proved that Stevioside stimulates these -cells to secrate more insulin and exerts antidiabetic effect Jeppesen, P. B., et al. ―Stevioside acts directly on pancreatic beta cells to secrete insulin: actions independent of cyclic adenosine monophosphate and adenosine triphosphate-sensitive K+-channel activity.‖ Metabolism. 2000; 49(2): 208–14.
  • 28. Dental caries (tooth decay) is a common consequence of common sugar consumption, because sugar forms a sticky coat on the teeth, which harbours many bacteria responsible tooth decay Stevioside does not help to form such sticky plaque on teeth. It also help to prevent dental cavities by inhibiting the bacteria Streptococcus mutans that stimulates plaque formation. Matsukubo, T., et al. "Sucrose substitutes and their role in caries prevention." Int. Dent. J. 2006 Jun; 56(3): 119-30.
