Uses
Used in Food and Beverage Industry:
Neosperidin dihydrochalcone is used as a natural sweetening agent for its intense sweetness, which is approximately 1,000 to 2,000 times sweeter than sucrose. It is particularly suitable for low-calorie or sugar-free products, as it provides sweetness without adding significant calories.
Used in Oral Care Products:
In the oral care industry, Neosperidin dihydrochalcone is used as a sweetening agent in chewing gum and dentifrices. Its sweetening properties help improve the taste of these products, while its antioxidant activity may contribute to oral health by combating free radicals and supporting gum health.
Used in Pharmaceutical Industry:
Due to its antioxidant properties, Neosperidin dihydrochalcone can be used in the pharmaceutical industry for developing drugs that target various health conditions. Its ability to combat oxidative stress may be beneficial in treating diseases associated with inflammation and oxidative damage.
Used in Cosmetics and Personal Care Products:
In the cosmetics and personal care industry, Neosperidin dihydrochalcone can be used as a natural sweetening agent in products like mouthwashes, toothpaste, and other oral care items. Its antioxidant properties may also provide additional benefits for skin health and protection against environmental stressors.
Production Methods
Neohesperidin dihydrochalcone is synthesized commercially from
either of the bitter-flavanones neohesperidin or naringin by catalytic
hydrogenation under alkaline conditions in a process first described
in the 1960s, in which neohesperidin is purified by recrystallization from water solutions.Neohesperidin dihydrochalcone is obtained
by the alkaline hydrogenation of neohesperidin.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Neosperidin dihydrochalcone is a ether-alcohol derivative. The ether being relatively unreactive. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert alcohols to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.
Fire Hazard
The flash point of Neosperidin dihydrochalcone has not been determined, but Neosperidin dihydrochalcone is probably combustible.
Flammability and Explosibility
Notclassified
Pharmaceutical Applications
Neohesperidin dihydrochalcone is a synthetic intense sweetening
agent approximately 1500–1800 times sweeter than sucrose and 20
times sweeter than saccharin. Structurally it is an analogue of
neohesperidin, a flavanone that occurs naturally in Seville oranges
(Citrus aurantium). Neohesperidin dihydrochalcone is used in
pharmaceutical and food applications as a sweetening agent and
flavor enhancer. The sweetness profile is characterized by a
lingering sweet/menthol-like aftertaste.The typical level used in
foods is 1–5 ppm although much higher levels may be used in
certain applications such as chewing gum. Synergistic effects occur
with other intense and bulk sweeteners such as acesulfame K,
aspartame, polyols, and saccharin.
In pharmaceutical applications, neohesperidin dihydrochalcone
is useful in masking the unpleasant bitter taste of a number of drugs such as antacids, antibiotics, and vitamins. In antacid preparations,
levels of 10–30 ppm result in improved palatability.
Safety
Neohesperidin dihydrochalcone is accepted for use in food products
either as a sweetener or flavor modifier in a number of areas
including Europe, USA, Australia, New Zealand, and several
countries in Africa and Asia. It is also used in a number of oral
pharmaceutical formulations.
Animal toxicity studies suggest that neohesperidin dihydrochalcone
is a nontoxic, nonteratogenic, and noncarcinogenic material at
the levels used in foods and pharmaceuticals.In Europe, an
acceptable daily intake of 0–5 mg/kg body-weight has been
established.
storage
Neohesperidin dihydrochalcone is stable for over three years when
stored at room temperature.
Accelerated stability studies on aqueous solutions stored at
30–60°C and pH 1–7 for 140 days indicate that neohesperidin
dihydrochalcone solutions are likely to be stable for 12 months at
room temperature and pH 2–6.Solutions formulated with some
or all of the water replaced by solvents with a lower dielectric
constant are reported to have longer shelf-lives.
The bulk material should be stored in a cool, dry, place protected
from light.
Check Digit Verification of cas no
The CAS Registry Mumber 20702-77-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,7,0 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 20702-77:
(7*2)+(6*0)+(5*7)+(4*0)+(3*2)+(2*7)+(1*7)=76
76 % 10 = 6
So 20702-77-6 is a valid CAS Registry Number.
