Taste-masking agents flavor

Alcohols—It is used in the range of 10-20%. Alcohol enhances the flavor, aids in masking the unpleasant taste of certain ingredients and also serve as solubilizing agent and preservative. 

There are four basic sensations salty, bitter, sweet, and sour. A combination of efforts is required to mask these tastes. For example, menthol and chloroform act as desensitizing agents a large number of natural and artificial flavors and their combinations are available to mask the bitterness most often found in organic compounds. Most formulators refer the selection of compatible flavors to companies manufacturing these flavors, as they may allow use of their drug master file... 

Aspartame is used as an intense sweetening agent in beverage products, food products, and table-top sweeteners, and in pharmaceutical preparations including tablets, powder mixes, and vitamin preparations. It enhances flavor systems and can be used to mask some unpleasant taste characteristics the approximate sweetening power is 180-200 times that of sucrose. 

Malic acid is used in pharmaceutical formulations as a general-purpose acidulant. It possesses a slight apple flavor and is used as a flavoring agent to mask bitter tastes and provide tartness. Malic acid is also used as an alternative to citric acid in effervescent powders, mouthwashes, and tooth-cleaning tablets. 

In aqueous alcoholic solutions, it very readily solubilizes essential oils. Aqueous solutions of hydrophobic drugs (e.g. miconazole, hexetidine, clotrimazole, benzocaine) can also be prepared with Cremophor EL. Cremophor EL has also been used as a solubilizing agent for drugs like cyclosporin A, paclitaxel, and cisplatin. Cremophor LLP is manufactured by purifying Cremophor EL and is therefore suitable for parenteral applications, e.g. Taxol preparations. In oral formulations, the taste of polyoxyl 35 castor oil (Cremophor EL) can be masked by a banana flavor. 

Products and Uses It is extracted from licorice root and is extremely sweet. Used as a tobacco humectant (prevents drying out), root beer foaming agent, in confectionery, chocolate, cocoa, and chewing gum. It masks the taste in pharmaceuticals such as aspirin. Used as a sweetener, nutrient, and flavoring. 

Licorice extracts are used extensively as ingredients in cough drops and syrups, tonics, laxatives, antismoking lozenges (see lobelia), and other preparations. They are also used as flavoring agents to mask bitter, nauseous, or other undesirable tastes in certain medicines (e.g., cascara, ammonium chloride, and quinine preparations).
