Odor masking formulations for natural compounds
The invention discloses odor masking formulations for stench natural compounds, selected from the extracts, fraction and pure phytochemicals that are produced in combination with a natural or synthetic hydrocolloid polymer gum(s). The invention further discloses novel process of producing the odor and taste masking formulations. The invention also discloses taste masking formulations of valerian extracts with no characteristic stench odor & or negligible stench odor in combination with natural hydrocolloid gum such as guar gum, acacia or other polymers. The invention further discloses method of reducing insomnia, anxiety, Attention Deficit Disorder (ADD), Chronic Fatigue Syndrome (CFS) using odor masking formulation of the current invention. Importantly, the said odor masked formulation of the present disclosure helps in improving sleep cycle and helps in efficient functioning of brain.

3. The odor masked nutraceutical or dietary supplement formulation as claimed in claim 1 , wherein the odor masked formulation is mixed with at least one additional ingredient selected from the group consisting of flavoring agents, sweeteners, effervescent materials, and pharmaceutically or nutraceutically accepted excipients, diluents or carriers.
4. The odor masked nutraceutical or dietary supplement formulation as claimed in claim 1 , where in the odor masked formulation is formulated into an oral dosage form selected from the group consisting of chewable tablets, orodispersible tablets, capsules, dry syrups, dry powders for suspension, suspensions, disintegrating tablets, fast dissolving tablets, and sachets.
5. An odor masked nutraceutical or dietary supplement formulation, comprising an obnoxious or stench causing natural compound and a hydrocolloid polymer;
wherein:
the obnoxious or stench causing natural compound is selected from the group consisting of a valerenic acid, an extract of a plant of the genus Valeriana , an extract of Murrava koenigii , an extract of Moringa oleifera , and combinations thereof;
the hydrocolloid polymer is a hydrocolloid polymer gum or a polyelectrolyte containing gum;
the ratio of the obnoxious or stench causing natural compound to the hydrocolloid polymer is in the range of 10:1 to 1:10; and
the obnoxious or stench causing natural compound is uniformly distributed within a three dimensional gel network of the hydrocolloid polymer.
6. The odor masked nutraceutical or dietary supplement formulation as claimed in claim 5 , wherein the hydrocolloid polymer is selected from the group consisting of Guar gum, Gum acacia, Gum Kondagogu, Gum Karaya, Xanthum gum, carrageenan, sodium alginate, locust bean gum, gum ghati, carbopol, HPMC, Tragacanth, semi synthetic celluloses, synthetic celluloses, and mixtures thereof.
7. A process for preparation of the odor masked nutraceutical or dietary supplement formulation as claimed in claim 5 , comprising;
a) solvating of the hydrocolloid polymer with a solvent to obtain a solvated polymer;
b) Mixing the solvated polymer with the obnoxious or stench causing natural compound to obtain a mixture; and
c) Drying the mixture to entrap the obnoxious or stench causing natural compound within the three-dimensional polymer network;
wherein the ratio of the obnoxious or stench causing natural compound to the hydrocolloid polymer is in the range of 10:1 to 1:10.
8. The process as claimed in claim 7 , wherein the hydrocolloid polymer gum or polyelectrolyte containing gum is selected from the group consisting of Guar gum, Gum acacia, Gum Kondagogu, Gum Karaya, Xanthum gum, carrageenan, sodium alginate, locust bean gum, gum ghati, carbopol, HPMC, Tragacanth, semi synthetic celluloses, synthetic celluloses, and mixtures thereof.
9. The process as claimed in claim 7 , wherein the solvent is selected from the group consisting of water, methanol, ethanol, propanol, isopropanol, acetone, and mixtures thereof.
10. The process as claimed in claim 7 , wherein solvating of the hydrocolloid polymer with a solvent is carried out using water as a solvent, and produces a hydrogel.
11. The process as claimed in claim 7 , wherein solvating of the hydrocolloid polymer with a solvent is carried out using an organic solvent, and produces an organogel.
12. The process as claimed in claim 7 , wherein:
the step of mixing comprises mixing the solvated polymer with the obnoxious or stench causing natural compound to obtain the mixture, wherein the ratio between the obnoxious or stench causing natural compound and the polymer is from 1:10 to 10:1; and
the step of drying the mixture is carried out in a vacuum dryer at 40-800° C.
13. The process as claimed in claim 7 , further comprising pulverizing the polymer network, and sieving the pulverized polymer network to obtain the odor masked nutraceutical or dietary supplement formulation.
14. A method of treating a disorder in a subject in need thereof, wherein the method comprises administering to the subject a therapeutically effective quantity of the odor masked nutraceutical or dietary supplement formulation of claim 1 ;
wherein treating the disorder comprises enhancing sleep; reducing anxiety, stress, or depression; treating insomnia; treating Attention Deficit Disorder (ADD); treating Chronic Fatigue Syndrome (CFS), or treating menopause in said subject.
