2. Sweeting agents are the substances which are
added to drug formulation to mask its bitter taste.
Ideal properties of Sweeteners
◦ compatible.
◦ sweetness even in low concentration.
◦ cheap and easily available.
◦ agreeable odour.
◦ heat stable.
◦ non toxic.
◦ inert.
◦ induce glycemic response.
3. 1. Nutritive sweetener-
Examples-Sucrose,sugar alcohol(Manittol,Sorbitol)
Fructose-4kcal/gm the same as surcose and it
does not cause fluctuation in blood sugar,thus
better choice in diabetic patient.
Less sweet and less caloric.
4. 2. Non-nutritive sweetener-
Examples includes--Saccharin, Aspartame,
Alitame, Acesulfane-K etc.
non- nutritive sweetener are more sweeter
and thus only small quantity is required for
sweeting preparation.
5. SWEETNESS POTENCY=
SWEETNESS OF 100 gm/Lt SUCROSE SOLUTION
g/Lt OF SWEETNER SOLUTION WITH EQUVALENT SWEETNESS
E.g. 0.75 gm/litre solution of aspartame
matches with the sweetness of 100 gm/litre
solution of sucrose.
Therefore aspartame is considered as 133
times sweeter than sucrose.
7. GLYCYRRHIZIN:
Synonyms-glycyrrhiza,jestha madhu
Source: Glycyrrhizin is a triterpenoid saponin
glycoside, obtained from roots and stolons of
Glycyrrhiza glabra
Family :-Leguminosae.
Properties:
It is 30–50 times as sweet as sucrose .
Odorless.
Maintains its sweetness under heating.
8. Chemical Constituents :-It is a triterpenoids glycoside.
H2O
Glycyrrhizic acid Glycyrrhetic acid (aglycone)+
2 molecules of glucuronic acid
The acid form is not particularly water-soluble, but its
ammonium salt is soluble in water at PH greater than 4.5.
It also contain liquirtin and liuiritigenin(flavonoid glycoside).
9. Preparation: A crude extract of liquorice root is to be
prepared with the help of counter current extraction
with water. After removal of polysaccharide,
Glycyrrizin can be precipitated from crude extract
with sulphuric acid
Uses: In the treatment of peptic ulcers and as an
expectorant, produce anti-inflammatory effects, is
used in the treatment of chronic hepatitis and cirrhosis.
10. STEVIOSIDE:
Source: It is Steviol glycoside obtained from leaves of
the Stevia rebaudiana family Compositeae.
Properties:
It is 160- 170 times sweeter than sucrose.
It is heat stable and pH stable and do not ferment.
It does not induce a glycemic response.
Natural sweetner to diabetics and carbohydrate
controlling diets.
11. Structure: It is made up from a diterpene known as Steviol.
Stevioside is formed by attaching glucose molecules to the
steviol structure.
12. Preparation: Dry the leaves in shade, powder into a grinder.
Treat it with non polar solvent then filter. Use the marc. Add
water to marc, filter, add tri carboxylic acid to the filterate.
Neutrilize with acid, and separate the precipitates of
Stevioside.
Uses- as Sweetning agent
13. NEOHESPERIDIN
DIHYDROCHALCONE:
Source------It is obtained from orange peels of
Citrus aurantium var. amara
Family:- Rutaceae
Properties:
It is 330 times sweeter than sucrose
It is prone to hydrolytic cleavage of hydrolytic bond, it is
stable under storage conditions.
14. Structure:
Preparation: It is prepared from neohesperidin by hydration
of neohesperidin under alkaline condition.
Use: It is used in confectionery, chewing gum, beverages and
dairy products.
15. THAUMATIN
Source: -It is obtained from the arils of fruits of
Thaumatococcus danielli
Family:- Marantaaceae.
Properties:
It is approximately 3500 times sweeter than sucrose
The sweetness shows delayed onset and long persistent
taste.It loses its sweetness on heating.
It is highly water soluble, stable below Ph 5.5.
16. Chemical Constituent:-It is a polypeptide containing
Thaumatin I & Thaumatin II as major components.
Preparation: It is extracted with water and then purified by Ion
exchange chromatography.
Use: It is used as flavor enhancer rather than as a sweetener. It is used
as flavor enhancer in confectionary, chewing gum and similar products.
17. MONELLIN:
Source: It is obtained from the fruits of
Dioscoreophyllum cumminsii
Family:- Menispermaceae
Properties: It is a polypeptide. It is 2000 times sweeter than sucrose.
Use: It is unstable to heat so rarely used as sweetener.
18. SUGAR:
Source: Sugar is extracted from stems of sugar cane,
Saccharum officinarum
Family:- Poaceae.
Preparation: Sugar cane is crushed to extract the juice. The
crushing process must break up the hard nodes of the cane and
flatten the stems. The juice is collected, filtered and sometimes
treated and then boiled to drive off the excess water.
19. Products of Sugar Cane:
1. White Sugar 6.Brown sugar
2. Jaggery 7. Ethanol
3. Molasses 8. Baggasse
4. Falernum 9. Rum
5.Cachaca (a traditional spirit from Brazil),
Use: Sweetening agent.
High Tech Uses of Sugar Cane
Bioelectricity: Leftover sugarcane biomass can be burned
and converted into electricity.
Bioplastics: Beverage containers, food packaging and other
consumer products made with sugarcane compared to standard
plastic.
Biohydrocarbons and Beyond: where scientists are using cane to
produce fuels that could replace gasoline,diesel and jet fuel
without needing petroleum.
20. HONEY:
Source: It is obtained from the flower
nectar sucked by the Honey bee of
Apis mellifera and Apis dorsata
Family:- Apidae
Chemical Constituents:-
Glucose(30-40%),Fructose(40-50%),Sucrose(0.1-
10%),Dextrin,Formic acid,Pollengrains,Traces of
gums,Vitamin,Proteins.
21. Preparation: It is obtained from the nectar of flower, where
Honey bee sucks the nectar, where it is partially used by Honey
bee and than it is converted to Invert sugar by the enzyme
invertase and diastase. This is deposited on the Honey comb. The
person, who collects the Honey, makes smoke around the Honey
comb so as to expel the Bees. The Honey comb then collected, it
is pressed by keeping in the muslin cloth. The Honey which oozes
is collected in a pot and allowed to separate the waxy material in
the pot itself. The wax comes on the surface of Honey which is
removed from Honey, it is then stored in Amber coloured container
22. Uses: Sweetening agent, in cough, in face pack with Aloe
vera and Santalum album, in weight loss management along with
lime juice i.e. Citrus sinensis, in Ayurvedic and Unani preparation
as vehicle. Used in dry fruit preparation like Battisa and Panjeri
preparation so as to remove body ache, back ache after child
birth. (This is scientifically to be proved)
