Abstract: Provided is an acid taste and/or acid smell-reducing agent that can effectively reduce acid taste/acid smell without adding off-taste and off-smell. The acid taste and/or acid smell-reducing agent is composed of 4,7-tridecadienal and/or 2,4,7-tridecatrienal and is added to a food or drink having acid taste and/or acid smell.

Abstract: [Object] An object of the present invention is to provide a sweet taste receptor-expressing construct which can functionally stably express both of a sweet taste receptor (T1R2+T1R3) and a G protein ? subunit at a high expression efficacy, and a stable expression cell body expressing the construct. [Solution] The sweet taste receptor-expressing construct of the present invention is such that respective genes encoding sweet taste receptor subunits T1R2 and T1R3, and a G protein ? subunit are inserted into the same plasmid. The cell body of the present invention is such that the sweet taste receptor-expressing construct of the present invention is gene-introduced into a 293 cell in which an FRT (Flippase Recognition Target) sequence is incorporated into one place in a genome, to express sweet taste receptor subunits T1R2 and T1R3, and a G protein ? subunit simultaneously.

Abstract: The present invention relates to improvement of the unpleasant taste characteristic of potassium salts without adversely affecting the salty taste of the potassium salts and provides a method for reducing sodium contents in foods and drinks without reducing salty taste of the foods and drinks and also provides sodium-reduced foods and drinks. The present invention relates to a taste-improving agent for a potassium salt or a potassium salt-containing food or drink, and the agent contains a phthalide as an active ingredient.

Abstract: The present invention provides a flavor composition that can impart an ORAC value of 1 ?molTE/g or more to foods. The flavor composition is prepared by mixing natural essential oils and flavor components having ORAC values.

Abstract: The present invention provides a manufacturing method of a flavor-containing particle composition characterized in that flavor, saccharide, and an oily substance having a softening point of 55 to 90° C. are mixed, the mixture is heated so as to bring the saccharide into a melted or a semi-melted state and then, cooled, solidified and crushed. With the flavor-containing particle composition obtained by the manufacturing method of the present invention, there is no dissipation caused by sublimation of the flavor, the flavor is completely encapsulated, preservation stability of aroma is good, fluidity of the powder is high, blocking is hard to occur even under a high-humidity environment, and moreover, flavor release occurs at desirable timing.

Abstract: This invention offers 6,8,10-undecatrien-3-ol and 6,8,10-undecatrien-4-ol. These compounds possess not only woody green note, but also fruity note rich in naturality and freshness, and aroma compositions blended therewith are useful for imparting fragrance and flavor to food and beverage, perfumed cosmetics, medicaments and the like.

Abstract: This invention offers 6,8,10-undecatrien-3-one or 6,8,10-undecatrien-4-one which are represented by the following formula (1) [in the formula, either one of A and B stands for carbonyl group and the other stands for methylene group, and the wavy line signifies cis-form, trans-form, or a mixture of cis- and trans-form at an optional ratio] and which can reproduce an odor rich in naturality and freshness.

Abstract: The present invention provides a sustained-release aromatic, characterized in that the aromatic comprises at least one perfume derivative as an active component selected from glycosides of perfumes, phosphoric acid ester derivatives of perfumes, amino acid derivatives of perfumes and carboxylic acid derivatives of perfumes, and contains no enzyme or acid which decomposes the perfume derivative, wherein the perfume derivative is decomposed by bacteria usually present on the skin or yeast to release a perfume component to exhibit aroma. The present invention also provides a method for the detection of micro-organisms using the aforesaid sustained-release aromatic. As the sustained-release aromatic of the present invention releases a perfume component only when it is decomposed by micro-organisms such as bacteria usually present on the skin or yeast, the amount of perfumes to be used can be extremely reduced. The sustained-release aromatic of the present invention is also excellent in keeping aroma.

Abstract: This invention provides a process for the production of .delta.-decalactone by the microbial reduction of massoia lactone, characterized in that a bacterium having the ability to reduce massoia lactone is used as the microorganism. The .delta.-decalactone produced according to this process has a highly tastable, mild creamlike scent and flavor, and is hence suitable for use in flavor compositions.
