Abstract

The present invention relates to a purified product of a citrus oil, in which an oil derived from a citrus peol is used as a raw material, a content of linoleic acid is 0.015 parts by mass or less with respect to 1 part by mass of citral, or 0.063 parts by mass or less with respect to 1 part by mass of linalool, or 0.083 parts by mass or less with respect to 1 part by mass of decanal, and a content of sesquiterpene hydrocarbons is 20 mass % or less.

First claim

a content of linoleic acid is 0.015 parts by mass or less with respect to 1 part by mass of citral, or 0.063 parts by mass or less with respect to 1 part by mass of linalool, or 0.083 parts by mass or less with respect to 1 part by mass of decanal, and a content of sesquiterpene hydrocarbons is 20 mass % or less.

2 . The purified product of a citrus oil according to claim 1 , wherein an oil derived from a lemon peel is used as a raw material,
a content of linoleic acid is 0.015 parts by mass or less with respect to 1 part by mass of citral, and a content of sesquiterpene hydrocarbons is 20 mass % or less.

3 . The purified product of a citrus oil according to claim 1 , wherein an oil derived from a lime peel is used as a raw material,
a content of linoleic acid is 0.008 parts by mass or less with respect to 1 part by mass of citral, and a content of sesquiterpene hydrocarbons is 20 mass % or less.

4 . The purified product of a citrus oil according to claim 1 , wherein an oil derived from an orange peel is used as a raw material,
a content of linoleic acid is 0.063 parts by mass or less with respect to 1 part by mass of linalool, and a content of sesquiterpene hydrocarbons is 10 mass % or less.

5 . The purified product of a citrus oil according to claim 1 , wherein an oil derived from a grapefruit peel is used as a raw material,
a content of linoleic acid is 0.083 parts by mass or less with respect to 1 part by mass of decanal, and a content of sesquiterpene hydrocarbons is 10 mass % or less.

6 . A fragrance or flavor composition, comprising the purified product of a citrus oil according to claim 1 .

7 . A beverage or food product, a fragrance or cosmetic product, a pharmaceutical product, or an oral care product, comprising the fragrance or flavor composition according to claim 6 .

8 . A production method of the purified product of a citrus oil according to claim 1 , comprising at least one selected from the group consisting of subjecting an oil as a raw material to an aqueous alkali solution washing treatment, subjecting an oil as a raw material to an ion exchange resin treatment, and subjecting an oil as a raw material to a treatment in which thin-film distillation and liquid-liquid extraction are combined.

9 . A production method of the purified product of a citrus oil according to claim 1 , comprising:
subjecting an oil as a raw material to an aqueous alkali solution washing treatment, wherein an alkali substance used in the aqueous alkali solution washing treatment is a strong base, and when the oil as the raw material is treated without being concentrated and is subjected to the aqueous alkali solution washing treatment, an amount of the alkali substance used is 0.05 mol or less with respect to 1 kg of a treatment target.

10 . A production method of the purified product of a citrus oil according to claim 1 , comprising:
