DESCRIPTION OF RELATED ART

The taste system provides sensory information about the chemical composition of the external world. Taste transduction is one of the more sophisticated forms of chemically triggered sensation in animals. Signaling of taste is found throughout the animal kingdom, from simple metazoans to the most complex of vertebrates. Mammals are believed to have five basic taste modalities: sweet, bitter, sour, salty, and umami/kokumi.

Umami is the taste most commonly associated with the savory taste of monosodium glutamate (MSG), meat products, cheeses, tomatoes, mushrooms, soy sauce, fish sauce, miso, and the like. Mammals generally perceive umami to be a pleasurable sensation. Kokumi is a related taste commonly associated with the taste of fermented products, soy sauce, fish sauce, and shrimp paste. Many of these typical sources of umami and kokumi taste are high in glutamic acid and salt, or rely on animal products.

Excessive sodium intake can cause a number of health-related problems. One such problem is hypertension. Hypertension is a condition in which the pressure of the blood against artery walls is high enough that it may eventually cause heart disease and other health problems. Excessive sodium intake also adversely affect the balance of water and minerals in the body. For example, excessive sodium intake can cause calcium loss, which can lead to osteoporosis and other problems. Excessive consumption of food products containing glutamic acid can also have certain adverse health effects, as glutamic acid interferes with the functioning of neurotransmitters. Thus, it is generally desirable to reduce the consumption of sodium and glutamic acid. Further, there is increased consumer demand for food and beverage products that do not contain animal-derived ingredients, such as animal-derived fats, meat products, or dairy products. Enhancement of salt, umami, or kokumi flavors provides an alternative approach to partially or completely replacing ingredients that are traditionally used to impart salt, umami, and/or kokumi taste. Even so, there is a limited number of compounds, especially naturally derived compounds, that can accomplish this effectively. Thus, there is a continuing need to discover new compounds having utility as flavor modifiers, especially compounds that enhance, among other flavors, the taste of salt, umami, kokumi, or any combination thereof.

Wherever a group is described as “optionally substituted” that group can be substituted with the above substituents.

It is to be understood that certain radical naming conventions can include either a mono-radical or a di-radical, depending on the context. For example, where a substituent requires two points of attachment to the rest of the molecule, it is understood that the substituent is a di-radical. For example, a substituent identified as alkyl that requires two points of attachment includes di-radicals such as -CH ₂ -, -CH ₂ CH ₂ -, -CH ₂ CH(CH ₃ )CH ₂ -, and the like.

Wherever a substituent is depicted as a di-radical (i.e., has two points of attachment to the rest of the molecule), it is to be understood that the substituent can be attached in any directional configuration unless otherwise indicated. Thus, for example, a substituent depicted as -AE- or includes the substituent being oriented such that the A is attached at the leftmost attachment point of the molecule as well as the case in which A is attached at the rightmost attachment point of the molecule.

As used herein, a squiggly bond adjacent to a carbon-carbon double bond indicates that the substituents around the carbon-carbon double bond may connect in either an E or Z configuration, or a combination of molecules in either configuration.

As used herein, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. For example, reference to “a substituent” encompasses a single substituent as well as two or more substituents, and the like.

As used herein, “for example,” “for instance,” “such as,” or “including” are meant to introduce examples that further clarify more general subject matter. Unless otherwise expressly indicated, such examples are provided only as an aid for understanding embodiments illustrated in the present disclosure, and are not meant to be limiting in any fashion. Nor do these phrases indicate any kind of preference for the disclosed embodiment.

As used herein, “comprise” or “comprises” or “comprising” or “comprised of’ refer to groups that are open, meaning that the group can include additional members in addition to those expressly recited. For example, the phrase, “comprises A” means that A must be present, but that other members can be present too. The terms “include,” “have,” and “composed of’ and their grammatical variants have the same meaning. In contrast, “consist of’ or “consists of’ or “consisting of’ refer to groups that are closed. For example, the phrase “consists of A” means that A and only A is present.

As used herein, “optionally” means that the subsequently described event(s) may or may not occur. In some embodiments, the optional event does not occur. In some other embodiments, the optional event does occur one or more times.

As used herein, “or” is to be given its broadest reasonable interpretation, and is not to be limited to an either/or construction. Thus, the phrase “comprising A or B” means that A can be present and not B, or that B is present and not A, or that A and B are both present. Further, if A, for example, defines a class that can have multiple members, e.g., Ai and Az, then one or more members of the class can be present concurrently.

As used herein, certain substituents or linking groups having only a single atom may be referred to by the name of the atom. For example, in some cases, the substituent “-H” may be referred to as “hydrogen” or “a hydrogen atom,” the substituent “-F” may be referred to as “fluorine” or “a fluorine atom,” and the linking group “-O-” may be referred to as “oxygen” or “an oxygen atom.”

Points of attachment for groups are generally indicated by a terminal dash (-) or by an asterisk (*). For example, a group such as *-CH ₂ -CH ₃ or -CH ₂ -CH ₃ both represent an ethyl group.

Chemical structures are often shown using the “skeletal” format, such that carbon atoms are not explicitly shown, and hydrogen atoms attached to carbon atoms are omitted entirely. For example, the structure represents butane (i.e., n-butane). Furthermore, aromatic groups, such as benzene, are represented by showing one of the contributing resonance structures. For example, the structure represents toluene.

As used herein, the term “conjugated diyne” refers to compounds of formula (I), any salts thereof, or any generic or specific embodiments thereof.

Other terms are defined in other portions of this description, even though not included in this subsection.

Typically at least a sweet receptor modulating amount, a sweet receptor ligand modulating amount, a sweet flavor modulating amount, a sweet flavoring agent amount, a sweet flavor enhancing amount, or a therapeutically effective amount of one or more of the present compounds will be added to the ingestible composition, optionally in the presence of sweeteners so that the sweet flavor modified ingestible composition has an increased sweet taste as compared to the ingestible composition prepared without the compounds of the present invention, as judged by human beings or animals in general, or in the case of formulations testing, as judged by a majority of a panel of at least eight human taste testers, via procedures commonly known in the field.

In some embodiments, compounds as disclosed and described herein, individually or in combination, modulate the sweet taste or other taste properties of other natural or synthetic sweet tastants, and ingestible compositions made therefrom. In one embodiment, the compounds as disclosed and described herein, individually or in combination, may be used or provided in its ligand enhancing concentration(s). For example, the compounds as disclosed and described herein, individually or in combination, may be present in an amount of from 0.001 ppm to 100 ppm, or narrower alternative ranges from 0.1 ppm to 50 ppm, from 0.01 ppm to 40 ppm, from 0.05 ppm to 30 ppm, from 0.01 ppm to 25 ppm, or from 0.1 ppm to 30 ppm, or from 0.1 ppm to 25 ppm, or from 1 ppm to 30 ppm, or from 1 ppm to 25 ppm.

In some embodiments, conjugated diynes as disclosed and described herein, individually or in combination, may be provided in a flavoring concentrate formulation, e.g., suitable for subsequent processing to produce a ready-to-use (i.e., ready-to-serve) product. By “a flavoring concentrate formulation”, it is meant a formulation which should be reconstituted with one or more diluting medium to become a ready-to-use composition. The term “ready-to-use composition” is used herein interchangeably with “ingestible composition”, which denotes any substance that, either alone or together with another substance, can be taken by mouth whether intended for consumption or not. In one embodiment, the ready-to-use composition includes a composition that can be directly consumed by a human or animal. The flavoring concentrate formulation is typically used by mixing with or diluted by one or more diluting medium, e.g., any consumable or ingestible ingredient or product, to impart or modify one or more flavors to the diluting medium. Such a use process is often referred to as reconstitution. The reconstitution can be conducted in a household setting or an industrial setting. For example, a frozen fruit juice concentrate can be reconstituted with water or other aqueous medium by a consumer in a kitchen to obtain the ready-to-use fruit juice beverage. In another example, a soft drink syrup concentrate can be reconstituted with water or other aqueous medium by a manufacturer in large industrial scales to produce the ready-to-use soft drinks. Since the flavoring concentrate formulation has the flavoring agent or flavor modifying agent in a concentration higher than the ready-to-use composition, the flavoring concentrate formulation is typically not suitable for being consumed directly without reconstitution. There are many benefits of using and producing a flavoring concentrate formulation. For example, one benefit is the reduction in weight and volume for transportation as the flavoring concentrate formulation can be reconstituted at the time of usage by the addition of suitable solvent, solid or liquid.

The flavored products set forth according to any of the foregoing embodiments, also include, in certain embodiments, one or more additional flavor-modifying compounds, such as compounds that enhance sweetness (e.g., hesperetin, naringenin, glucosylated steviol glycosides, etc.), compounds that block bitterness, compounds that enhance umami, compounds that reduce sourness, compounds that enhance saltiness, compounds that enhance a cooling effect, or any combinations of the foregoing.

In certain embodiments of any aspects and embodiments set forth herein that refer to a sweetening or flavoring concentrate, the sweetening or flavoring concentrate is a non-naturally-occurring product, such as a composition specifically manufactured for the production of a flavored product, such as food or beverage product.

In one embodiment, the flavoring concentrate formulation comprises i) compounds as disclosed and described herein, individually or in combination; ii) a carrier; and iii) optionally at least one adjuvant. The term “carrier” denotes a usually inactive accessory substance, such as solvents, binders, or other inert medium, which is used in combination with the present compound and one or more optional adjuvants to form the formulation. For example, water or starch can be a carrier for a flavoring concentrate formulation. In some embodiments, the carrier is the same as the diluting medium for reconstituting the flavoring concentrate formulation; and in other embodiments, the carrier is different from the diluting medium. The term “carrier” as used herein includes, but is not limited to, ingestibly acceptable carrier.

The term “adjuvant” denotes an additive which supplements, stabilizes, maintains, or enhances the intended function or effectiveness of the active ingredient, such as the compound of the present invention. In one embodiment, the at least one adjuvant comprises one or more flavoring agents. The flavoring agent may be of any flavor known to one skilled in the art or consumers, such as the flavor of chocolate, coffee, tea, mocha, French vanilla, peanut butter, chai, or combinations thereof. In another embodiment, the at least one adjuvant comprises one or more sweeteners. The one or more sweeteners can be any of the sweeteners described in this application. In another embodiment, the at least one adjuvant comprises one or more ingredients selected from the group consisting of a emulsifier, a stabilizer, an antimicrobial preservative, an antioxidant, vitamins, minerals, fats, starches, protein concentrates and isolates, salts, and combinations thereof. Examples of emulsifiers, stabilizers, antimicrobial preservatives, antioxidants, vitamins, minerals, fats, starches, protein concentrates and isolates, and salts are described in U.S. Pat. No. 6,468,576, the content of which is hereby incorporated by reference in its entirety for all purposes.

In one embodiment, the present flavoring concentrate formulation can be in a form selected from the group consisting of liquid including solution and suspension, solid, foamy material, paste, gel, cream, and a combination thereof, such as a liquid containing certain amount of solid contents. In one embodiment, the flavoring concentrate formulation is in form of a liquid including aqueous-based and nonaqueous-based. In some embodiments, the present flavoring concentrate formulation can be carbonated or non-carbonated.

The flavoring concentrate formulation may further comprise a freezing point depressant, nucleating agent, or both as the at least one adjuvant. The freezing point depressant is an ingestibly acceptable compound or agent which can depress the freezing point of a liquid or solvent to which the compound or agent is added. That is, a liquid or solution containing the freezing point depressant has a lower freezing point than the liquid or solvent without the freezing point depressant. In addition to depress the onset freezing point, the freezing point depressant may also lower the water activity of the flavoring concentrate formulation. The examples of the freezing point depressant include, but are not limited to, carbohydrates, oils, ethyl alcohol, polyol, e.g., glycerol, and combinations thereof. The nucleating agent denotes an ingestibly acceptable compound or agent which is able to facilitate nucleation. The presence of nucleating agent in the flavoring concentrate formulation can improve the mouthfeel of the frozen Blushes of a frozen slush and to help maintain the physical properties and performance of the slush at freezing temperatures by increasing the number of desirable ice crystallization centers. Examples of nucleating agents include, but are not limited to, calcium silicate, calcium carbonate, titanium dioxide, and combinations thereof.

In one embodiment, the flavoring concentrate formulation is formulated to have a low water activity for extended shelf life. Water activity is the ratio of the vapor pressure of water in a formulation to the vapor pressure of pure water at the same temperature.

The actual techniques for preparing such dried forms are well-known.

In some embodiments, the tabletop sweetener can be made to be similar to brown sugar. In such embodiments, compounds imparting brown notes can be added to the composition to make it taste more similar to brown sugar.

In some embodiments, the flavorings may be used in many distinct physical forms well- known in the art to provide an initial burst of flavor and/or a prolonged sensation of flavor. Without being limited thereto, such physical forms include free forms, such as spray dried, powdered, beaded forms, encapsulated forms, and mixtures thereof.

Suitable bulking agents include, but are not limited to maltodextrin (10 DE, 18 DE, or 5 DE), com syrup solids (20 or 36 DE), sucrose, fructose, glucose, invert sugar, sorbitol, xylose, ribulose, mannose, xylitol, mannitol, galactitol, erythritol, maltitol, lactitol, isomalt, maltose, tagatose, lactose, inulin, glycerol, propylene glycol, polyols, polydextrose, fructooligosaccharides, cellulose and cellulose derivatives, and the like, and mixtures thereof. Additionally, granulated sugar (sucrose) or other caloric sweeteners such as crystalline fructose, other carbohydrates, or sugar alcohols can be used as a bulking agent due to their provision of good content uniformity without the addition of significant calories.

In one embodiment, the at least one bulking agent may be a bulking agent described in U.S. Patent No. 8,993,027.

In one embodiment, the at least one bulking agent may be a bulking agent described in U.S. Patent No. 6,607,771.

In one embodiment, the at least one bulking agent may be a bulking agent described in U.S. Patent No. 6,932,982.

In some embodiments, the tabletop sweetener composition may further comprise at least one anti-caking agent. As used herein the phrase "anti-caking agent" and "flow agent" refer to any composition which prevents, reduces, inhibits, or suppresses the at least one sweetener from attaching, binding, or contacting to another sweetener molecule. Alternatively, anti-caking agent may refer to any composition which assists in content uniformity and uniform dissolution. Non- limiting examples of anti-caking agents include cream of tartar, calcium silicate, silicon dioxide, microcrystalline cellulose (Avicel, FMC BioPolymer, Philadelphia, Pa.), and tricalcium phosphate. In one embodiment, the anti- caking agents are present in the tabletop sweetener composition in an amount from about 0.001 to about 3% by weight of the tabletop sweetener composition.

In some embodiments, the sweetener compositions of any of the preceding aspects and embodiments thereof are encapsulated using typical means for encapsulating flavor or fragrance compounds. Non-limiting examples of such technology are set forth in U.S. Patent Application Publication Nos. 2016/0235102, 2019/0082727, 2018/0369777, 2018/0103667, 2016/0346752, 2015/0164117, 2014/0056836, 2012/0027866, 2010/0172945, and 2007/0128234, as well as U.S. Patent Nos. 7,488,503, 6,416,799, 5,897,897, 5,786,017, 5,603,971, 4,689,235, 4,610,890, 3,704,137, 3,041,180, and 2,809,895. All of the preceding patent publications and patents are hereby incorporated by reference as though set forth herein in their entireties.

Non- Animal Protein Materials and Products Made Therefrom

Products intended to replace or substitute meat or dairy products often rely on various non-animal-based materials, such as starches and proteins derived from plants, algae, and fungi, to simulate the texture and flavor of meat or dairy. Non-limiting examples of such plant proteins include soy proteins, pea proteins, bean proteins, grain proteins, and the like. Due to compositional differences between such plant-based materials and animal-derived materials, such as a lack of glutamate-containing proteins and glutathione, these products can lack the umami and/or kokumi taste that consumers traditionally associate with meat or dairy products.

Thus, in certain aspects, the disclosure provides a flavored product comprising a plant-based material (such as a plant-based starch, a plant-based protein, or a combination thereof) and an conjugated diyne (according to any aspects and embodiments set forth herein), or a comestibly acceptable salt thereof. In some further embodiments, the flavored product can include any features of combination of features set forth above for ingestible compositions that contain the conjugated diyne, or a comestibly acceptable salt thereof. In some embodiments, the flavored product is a beverage, such as soy milk, almond milk, rice milk, oat milk, a protein drink, a meal-replacement drink, or other like product. In some other embodiments, the flavored product is a meat-replacement product, such as a plant-based chicken product (such as a plant-based chicken nugget), a plant-based beef product (such as a plant-based burger), and the like. In some other embodiments, the flavored product is a protein powder, a meal-replacement powder, a plant-based creamer for coffee or tea, and the like. In certain further embodiments, any such products contain additional ingredients, and have additional features, as are typically used in the preparation and/or manufacture of such products. For example, such an conjugated diyne, or comestibly acceptable salts thereof, may be combined with other flavors and taste modifiers, and may even be encapsulated in certain materials, according to known technologies in the relevant art. Suitable concentrations of the conjugated diyne, or comestibly acceptable salts thereof, are set forth above.

In some further embodiments analogous to the above embodiments, proteins or starches from algal or fungal sources can be used instead of or in combination with plant starches or proteins.

Non-Meat Protein Materials and Products Made Therefrom

Certain non-meat animal proteins, such as dairy proteins and proteins from bone broth, are commonly used in food products, and are also sold as the primary ingredient in certain protein powders. Such proteins can impart flavors that lack the full umami or kokumi taste that consumers may desire. This is especially true for protein isolates, such as protein isolates of whey protein, collagen protein, casein proteins, and the like. Thus, the present disclosure provides ingestible compositions that include non-meat animal proteins and the conjugated diyne (according to any aspects and embodiments set forth herein), or a comestibly acceptable salt thereof. The conjugated diyne, or its comestibly acceptable salts, can be present in any suitable combination, according to the embodiments set forth in the preceding sections of the present disclosure. In some embodiments, the non-meat animal protein is a bone protein, such as a collagen protein derived from the bones of an animal, such as a cow, pig, donkey, horse, chicken, duck, goat, goose, rabbit, lamb, sheep, buffalo, ostrich, camel, and the like. In some embodiments, the non-meat animal protein is a milk protein, such as a whey protein, a casein protein, or any combination thereof. The milk can be the milk of any suitable animal, such as a cow, donkey, horse, sheep, buffalo, camel, and the like.

The conjugated diyne, or its comestibly acceptable salts, can also be included in certain food or beverage products that include animal milk or materials derived from animal milk. Such products include cheeses, cheese spreads, yogurt, kefir, milk, processed dairy products, cottage cheese, sour cream, butter, and the like. Methods of Preparation

The compounds disclosed herein may be synthesized by methods described below, or by modification of these methods. Ways of modifying the methodology include, among others, temperature, solvent, reagents etc., known to those skilled in the art. In general, during any of the processes for preparation of the compounds disclosed herein, it may be necessary or desirable to protect sensitive or reactive groups on any of the molecules concerned.

To further illustrate this invention, the following examples are included. The examples should not, of course, be construed as specifically limiting the invention. Variations of these examples within the scope of the claims are within the purview of one skilled in the art and are considered to fall within the scope of the invention as described, and claimed herein. The reader will recognize that the skilled artisan, armed with the present disclosure, and skill in the art is able to prepare and use the invention without exhaustive examples.

Example 1 - Product Isolation

5.5 Kg of fresh stems and leaves of Chrysanthemum nankingense were cut into pieces and extracted with 95% ethanol. The solution was concentrated by a rotor vaporator under reduced pressure and loaded on an MCI column. The column was rinsed with water, 60% and 90% ethanol to get three fractions, Frl, Fr2, and Fr3. Fr3 was further subjected to silica gel column elution by cyclohexane and ethyl acetate in gradient to afford four sub-fractions. The third sub-fraction, which contained most of the alkylamides, was chosen for further separation with preparative LC chromatography. Solvent systems A (water) and B (acetonitrile) were used for the prep-HPLC separation on a phenomenex C18(2) column (150*21.20 mm*5pm). Gradient elution program (60%B to 70%B) was used for each separation. Peaks were collected using a fraction collector at UV 250 nm. Three alkylamides were obtained: nona-6,8-diynoic acid piperidide (Compound 101, 505 mg), nona-6,8-diynoic acid piperideide (Compound 102, 60 mg) and (E,E)-2,4-undecadien-8,10-diynoic acid piperidide (Compound 130, 485 mg). The structures were determined by NMR and HR ESI MS spectrum. The molecular weight of the [M+H]+ molecular ion was determined as follows for the three compounds:

Compound 101 218.1537 amu;

Compound 102 216.1378 amu; and Compound 130 242.1537 amu.

Table 2 below provides the ³ H and ¹³ C NMR spectrum data for Compound 101, Compound 102, and Compound 130.

Table 2 Example 2 - Synthesis of Compounds 103-118

N-bromosuccinimide (NBS, 10.3 g), silver nitrate (8.56 g), and triisopropylsilaneacetylene (TIPS-acetylene) (11.2 mL) were added to 400 mL of acetone (pre-dried). The solution was stirred vigorously for 3.5 hours at room temperature. Once the reaction reached completion (as shown by GC-MS), 300 mL of water was added. The resulting solution was extracted into cyclohexane (3 x 500 mL). The combined organic layer was washed with brine (2 x 500 mL), dried over anhydrous magnesium sulfate, filtered, concentrated, and dried further via a rotary evaporator to give a clear oil product (13.4247 g), which was determined to be l-(bromoethynyl)triisopropylsilane (Product 2a).

Copper (I) chloride (156 mg) was added to a 30% n-BuNH2 (butylamine) aqueous solution (130 mL) at room temperature, which resulted in the formation of a blue solution. A few crystals of hydroxylamine hydrochloride were added to discharge the blue color. After putting the solution in an ice- water bath, 6-heptynoic acid (3.7 g) in ethyl ether (50 mL) was added dropwise to the cooled reaction mixture. Occasionally adding a small amount of hydroxylamine hydrochloride was necessary to keep the color of the reaction a light yellow. After adding Product 2a (usually 30 minutes), the cooling bath was removed. The reaction mixture was stirred at room temperature for another 2 hours during which more crystals of hydroxylamine hydrochloride was added whenever the reaction mixture started to turn blue or green. Once the reaction completed (as shown by GC-MS), the reaction mixture was quenched and adjusted to a pH of about 2 by adding 2N hydrochloric acid (250 mL). The resulting solution was extracted into ethyl acetate (3 x 400 mL). The combined organic layer was washed with brine (1 x 500 mL), dried over magnesium sulfate, filtered, concentrated, and dried via a rotary evaporator to give a product of 9-TIPS-6,8-diynoic acid (Product 2b).

Under an atmosphere of nitrogen gas, tetra-n-butylammonium fluoride (TBAF) (IM solution in tetrahydrofuran (THF), 45 mL) was added dropwise to a solution of Product 2b (9.2 g) in 66 mL of THF at 0 °C. The solution was stirred at room temperature for 3-4 hours. Once the reaction reached completion (as shown by GC-MS), the reaction mixture was quenched with 2N Hydrochloric acid and adjusted to a pH of about 2 (150 mL). The reaction product was extracted with dichloromethane (DCM) (3 x 500 mL). The combined organic layers were washed with brine (2 x 500 mL), dried over magnesium sulfate, filtered, concentrated and dried via rotary evaporator to give a crude product. The total crude product was purified by flash chromatography (CHA/DCM) to afford nona-6,8-diynoic acid (3.9201 g) (Product 2c).

The resulting amides Compounds 103-118 were formed by amidating Product 2c with the appropriate amine. The amines used were as follows: Compound 103 (isobutylamine); Compound 104 (2-methylbutylamine); Compound 105 (beta-phenethylamine); Compound 106 (4-hydroxy-3 -methoxybenzylamine); Compound 107 (4-hydroxy-4-methoxy- benzylamine); Compound 108 (benzylamine); Compound 109 (butylamine); Compound 110 (tyramine); Compound 111 (4-methoxyphenethylamine); Compound 112 (ethanolamine);

Compound 113 (4-hydroxybenzylamine); Compound 114 (3,4-dimethoxyphenethylamine);

Compound 115 (2-hydroxy-2-methylpropylamine); Compound 116 (3,4-methylenedioxy- phenethylamine); Compound 117 (l-aminopropan-2-one); and Compound 118 (pyrrolidine).

The molecular weight of the [M+H]+ molecular ion was determined as follows for the following compounds:

Compound 103 206.1547 amu;

Compound 104 220.1705 amu;

Compound 105 254.1547 amu;

Compound 106 286.1446 amu;

Compound 107 286.1447 amu;

Compound 108 240.1393 amu;

Compound 109 206.1546 amu;

Compound 110 270.1495 amu;

Compound 111 284.1657 amu;

Compound 112 194.1181 amu;

Compound 113 256.1338 amu;

Compound 114 314.1759 amu;

Compound 115 222.1486 amu;

Compound 116 298.1433 amu;

Compound 117 206.1173 amu; and

Compound 118 204.1380 amu.

Example 3 - Sensory Testing for Salt Enhancement

Compounds 101 and 130 were evaluated for their salt-enhancement effects by a panel of 20 taste testers. The test compounds were added to solutions (0.25 wt%) sodium chloride, and tested for their sale enhancement effect relative to the same salt solution without the enhancer. Table 4 summarizes the results.

Table 4

Example 4 - Sensory Testing for Cooling/Burning

During tastings, 42 mg/L of Compound 130 in water solution was described as having a long-lasting warm, hot, weak cooling after taste, as well as bitter and astringent. At 20 mg/L, the taste attributes were selected as astringent, bitter, salty, earthy, herbal, and cooling, but no warm and hot sensation was perceived. At 2 mg/L, Compound 130 was tasteless.

A sample of 125 mg/L of Compound 101 in water solution was perceived as tingling (mid intensity), bitter, metallic, astringent and triggered an uncomfortable feeling in the throat when swallowed. At 39.2 mg/L, the tingling effect was weak. At 20 mg/L, the taste attributes of Compound 101 were perceived as astringent, bitter, herbal, earthy and green. At 2 mg/L, Compound 101 was tasteless.
