5. What is Novel food?
Novel food is a nutritional source that has not been used in
the past or one that has been made by a new manufacturing
process including e.g
Genetic modification.
Novel food is defined as a type of food that does not
have a significant history of consumption or is produced
by a method that has not previously been used for food.
Novel foods or novel food ingredients have no history of
“Significant” consumption in the European Union prior to 15
May 1997. Any food or food ingredient that falls within this
definition must be authorized according to “Novel Food”
legislation, Regulation (EC) no. 258/97 of the European
Parliament and of the council.
Some examples of novel foods are
 Stevia
 Tagatose
 chia seeds
 UV-treated milk
 Miracle fruit
 Astaxanthin
 Rapeseed protein
 Boabob

6. Introduction to Stevia as Novel food
Stevia is a sweetener and sugar
substitute derived from the leaves
of the plant species Stevia
rebaudiana
Stevia rebaudiana plant is found
in Brazil and Paraguay Central
America, Thailand, Korea, China
and India
This plant contains Steviol
glycosides are the chemical
compounds responsible for the
sweet taste.
Steviol glycosides present in Stevia
rebaudiana are 30 and 320 times
sweeter than sucrose.
They also occur in the related
species Stevia phlebophylla (but in
no other species of Stevia and in
the plant Rubus chingii

7. S. rebaudiana plant is a source of Stevia

Clade: Angiosperms
Clade: Eudicots
Clade: Asterids
Order: Asterales
Family: Asteraceae
Genus: Stevia
Species: S. rebaudiana

Stevia rebaudiana

8. Stevia
Historical Background:
Stevia has been used over centuries by
the Guaraní people of Brazil and Paraguay, who
called it kaʼa heʼẽ ("sweet herb"), to sweeten the
local yerba mate tea, as medicine, and as a "sweet
treat”
In 1899, botanist Moisés Santiago Bertoni first
described the plant as growing in eastern
Paraguay, and observed its sweet taste.
In 1931, chemists M Bridel and R Lavielle
isolated the glycosides stevioside and
rebaudioside that give the leaves their sweet taste.
The exact structures of the aglycone steviol and its
glycosides were published in 1955.

10. Novelty
 In 1991, the FDA refused to approve stevia as a sweetener as an additive in foods.
However, in 2008, after the purification process was developed and patented by Coca-
Cola, the FDA approved the stevia extracts as GRAS.
 Based on the JECFA (Joint Expert Committee on Food Additives) declaration, safe
consumption of steviol glycosides for humans is determined to be 4 mg per kg body
weight per day.
 It was also agreed by the European Commission in 2011 for use in food in European
countries. Steviol glycosides have also been accepted in the US as GRAS (Generally
Recognized as Safe).
 Stevia leaf and raw extracts are not treated as GRAS and their import into the US is
not allowed for usage as sweeteners. Nutrition, Center for Food Safety and Applied (9
February2019). "Additional Information about High-Intensity Sweeteners Permitted for
Use in Food in the United States". FDA.
 Note:
Stevioside was found to be nontoxic in acute toxicity studies.

11. Importance
Stevia is very important to us because of following facts.
Diabetes
Research has shown that stevia sweeteners do not contribute calories or carbohydrates to the
diet. They have also demonstrated no effect on blood glucose or insulin response. This allows
people with diabetes to eat a wider variety of foods and comply with a healthful meal plan.
In one of these studies, subjects with type 2 diabetes reported that stevia triggered significant
reductions in blood glucose and glucagon response after a meal.
Weight control
Stevia contains no sugar and very few, if any, calories. It can be part of a well-balanced diet
to help controll weight.
Pancreatic cancer
Stevia contains many sterols and antioxidant compounds, including kaempferol. Studies
have found that kaempferol can reduce the risk of pancreatic cancer by 23 percent.

12. Blood pressure
Certain glycosides in stevia extract have been found to dilate blood vessels. They can
also increase sodium excretion and urine output. A 2003 study showed that stevia could
potentially help lower blood pressure. The study suggested that the stevia plant might
have cardiotonic actions. Cardiotonic actions normalize blood pressure and regulate the
heartbeat.
Children's diets
Foods and beverages containing stevia can play an important role in decreasing calories
from unwanted sweeteners in the diets of children. There are now thousands of products
on the market containing naturally-sourced stevia, ranging from salad dressings to snack
bars. This availability allows children to consume sweet foods and drinks without the
added calories while transitioning to a lower sugar diet.
Allergies
In 2010, the European Food Safety Committee (EFSA) reviewed existing literature to
determine if there was any cause for concern regarding the potential for allergic reactions
to stevia. Even the highly purified forms of stevia extract are highly unlikely to cause an
allergic reaction. No cases of allergic reaction to stevia have been recorded since 2008.

13. Utilization
Stevia commonly utilized in
 Daily intake as zero calorie sugar
 Pharmaceutical
 Beverage industry
 Dog food
 Agriculture
 Forming
 Medical field
 Confectionary
 Tea industry

14. Applications of Stevia
 Mixed with other sweeteners
Enhances the taste and pleasantness when used with other sweeteners such as sucrose, glucose or
fructose. It is suitable in replacing 40-60% of sucrose used in food products thereby reducing the
production cost.
 Biscuits and Cookies
Stevia can preserve the crispiness and crunchiness of cookies and biscuits when use in place of
sugar.
 Preserved Food
It’s large molecular weight makes it less likely to be absorbed into preserved or canned food. This
helps to retain the original taste and freshness of the food. It also prevents the stickiness and
fermentation normally caused by sucrose
 Chewing Gum
Provides a long and lingering sweetness, great for the production of sugarless gums
 Sauce products
Harmonises very well with salt to give it a deeper variety of taste. It can maintain a pleasant colour
even when cooked in high heat.
 Pharmaceutical
Acts as a suppressing agent for removing unwanted flavours in medication.
 Feedstuff
Known to improve the palatability of animal feeds, thereby reducing feeding times and improving the
appetite of livestocks.
 Alcoholic Beverages
Readily dissolves in alcohol without reaction to its taste and properties.

15. Future Scope of Stevia:
The global stevia market is gaining from the
rising demand for stevia due to its high-
intensity of sweetness and low-calorie
content.
Stevia is sold as
Powder
Liquid
Leaf
Global Stevia Market was 895 Million US$
in 2018 and is Expected to Grow at a
CAGR of 3.84% Between 2019 and 2025 -
Valuates Reports
The stevia market is anticipated to grow at a
CAGR of ~ 7% during the forecast period of
2019-2029.
The global stevia market is a moderately
competitive market, with tier-1 players
holding ~35% - 40% share of the market.
Noteworthy investments in the research and
development for novel and sturdy products
is projected to boost the growth prospects
of the stevia market.

16. Major players in the stevia market are Cargill Incorporated, Ingredion Incorporated,
PureCircle Ltd., Koninklijke DSM NV, Tate and Lyle Plc., Sunwin Stevia International, Inc.,
GLG Life Tech Corp, Evolva Holding SA and others

17. Due to more advantages and broad applications makes Stevia very
important novel food. So future scope of Stevia is very bright. It ’ll play
very impressive role in share market as sugar substituent.
