Materials and methods for producing nut butter replicas from individual components are provided herein.

The invention relates to compounds that specifically bind a T1R1/T1R3 or T1R2/T1R3 receptor or fragments or sub-units thereof. The present invention also relates to the use of hetero-oligomeric and chimeric taste receptors comprising T1R1/T1R3 and T1R2/T1R3 in assays to identify compounds that respectively respond to umami taste stimuli and sweet taste stimuli. Further, the invention relates to the constitutive of cell lines that stably or transiently co-express a combination of T1R1 and T1R3; or T1R2 and T1R3; under constitutive or inducible conditions. The use of these cells lines in cell-based assays to identify umami and sweet taste modulatory compounds is also provided, particularly high throughput screening assays that detect receptor activity by use of fluorometric imaging.

An agent containing at least one aroma compound selected from the group consisting of E-beta-damascone, S-(2-methyl-3-furyl)ethanethioate, beta-caryophyllene oxide, beta-ionone, 2,5-dihydroxy-1,4-dithiane, methyl anthranilate, S-furfuryl thioformate, 1-isothiocyanate-3-(methylthio)propane, nootkatone, 1,4-dioxacycloheptadecane-5,17-dione, sclareol, and sclareolide is effective for masking an unpleasant smell and for making oral products in which an unpleasant smell is masked.

The present disclosure relates to a stabilized or more stable volatile compound, e.g., menthol, compositions and methods of making and using them including a mixture of a stabilizer compound of formula (I), for example, undecylenic acid methyl ester, undecylenic acid or a salt thereof and a volatile compound where the volatile compound is less susceptible to volatizing into a gas.

An object of the present invention is to provide a solid composition that provides green layer aroma and makes one feel its aroma in a sustained way when added to a medium such as water. The solid composition comprises dimethyl sulfide and β-ionone, and has a weight ratio of β-ionone content to dimethyl sulfide content which is adjusted to be in the range of from 0.003 to 3.

The present invention relates to a fragrance or flavor composition comprising a fragrance or flavor component acting on at least one olfactory receptor polypeptide selected from the group consisting of (a) OR2C1 and OR4Q3, and (b) polypeptides which comprise an amino acid sequence sharing an identity of at least 80% with the amino acid sequence of any of the polypeptides in (a) and which are responsive to at least one offensive odor-causing substance selected from the group consisting of trans-2-nonenal, trans-2-octenal, 1-octen-3-one, 1,5-octadien-3-one, 1-octen-3-ol and 1,5-octadien-3-ol to suppress the response intensity of the olfactory receptor polypeptide(s) to at least one of the offensive odor-causing substances, and also relates to a product comprising this fragrance or flavor composition and a method for suppressing offensive odors.

An object is to provide a novel saccharide-reduced fruit beverage having an improved flavor. According to the present invention, provided is a fruit beverage containing citrus fruit and having a sucrose concentration of 1.4 g/100 mL or less in terms of Brix 11°, in which the beverage has an ethyl ester concentration of 25 to 50 ppb and/or a monoterpene derivative concentration of 600 to 3,000 ppb. The citrus fruit in the present invention can be selected from the group consisting of oranges, grapefruit, and Unshu mikan, and a proportion of a fruit juice in the beverage can be set to 30% or more.

A process for producing rotundone from α-guaiene, in particular by oxidation of the C(3) position, wherein the α-guaiene is produced from a precursor by a sesquiterpene synthase. The sesquiterpene synthase is produced in a microorganism.

To provide an edible ingredient having an exceptional effect for enhancing umami.

An umami-enhancing composition having a carotenoid degradation product as an active ingredient. The umami-enhancing composition can be formulated through a manufacturing method that includes a step for adding a carotenoid to an edible oil and fat, and a step for degrading the carotenoid in the edible oil and fat. The carotenoid degradation product is preferably a degradation product of one or more selected from the group consisting of carotenes and xanthophylls. The umami-enhancing composition is optimally used as a food-product ingredient, etc., for manufacturing a seasoning or extract or for enhancing the umami of a food product.
