Abstract
The present invention addresses the problem of providing a versatile, flavorful long-chain polyunsaturated fatty-acid-containing fat having exceptional oxidation stability, and a food that utilizes the fat. The problem can be solved by a long-chain polyunsaturated fatty-acid-containing fat having a specific linoleic acid content and a specific tocopherol-tocotrienol content, the fat containing a fatty acid having five or more double bonds.
Claims13
A long-chain polyunsaturated fatty acid-containing fat comprising 1 to 35 parts by weight of linoleic acid and 0.001 part by weight to 0.05 part by weight of total amount of the following components (A), on the basis of 1 part by weight of the content of a long-chain polyunsaturated fatty acid having 5 or more double bonds in the constituent fatty acid composition, wherein
- components (A):
- β-tocopherol, γ-tocopherol, δ-tocopherol, β-tocotrienol, γ-tocotrienol and δ-tocotrienol.
A long-chain polyunsaturated fatty acid-containing fat comprising 7% by weight or more and 30% by weight or less of a long-chain polyunsaturated fatty acid having 5 or more double bonds in the constituent fatty acid composition, and 1 to 5 parts by weight of linoleic acid and 0.001 part by weight to 0.05 part by weight of total amount of the components (A), on the basis of 1 part by weight of the content of the long-chain polyunsaturated fatty acid having 5 or more double bonds in the constituent fatty acid composition, wherein a peroxide value after three days obtained from a preservation test of the long-chain polyunsaturated fatty acid-containing fat described below is 65 meq/kg or less:
- (Method of preservation test of long-chain polyunsaturated fatty acid-containing fat)
- putting 30 g of uniformly mixed fat into a 100-ml Erlenmeyer flask;
- letting the Erlenmeyer flask opened to contact with air;
- and
- stirring the Erlenmeyer flask in a thermostatic shaking incubator (rotation number:
- 100 rpm, set at 60° C.) with heating.
A long-chain polyunsaturated fatty acid-containing fat comprising 1.5% by weight or more and less than 7% by weight of a long-chain polyunsaturated fatty acid having 5 or more double bonds in the constituent fatty acid composition, and 5 to 35 parts by weight of linoleic acid and 0.001 part by weight to 0.05 part by weight of total amount of the components (A), on the basis of 1 part by weight of the content of the long-chain polyunsaturated fatty acid having 5 or more double bonds in the constituent fatty acid composition, wherein a peroxide value after three days obtained from the preservation test of the long-chain polyunsaturated fatty acid-containing fat is 40 meq/kg or less.
A method for suppressing increase in peroxide value of a long-chain polyunsaturated fatty acid-containing fat comprising making a content of linoleic acid to 1 to 35 parts by weight and the total amount of the components (A) to 0.001 part by weight to 0.05 part by weight, on the basis of 1 part by weight of the content of the long-chain polyunsaturated fatty acid having 5 or more double bonds in the constituent fatty acid composition.
A method for suppressing increase in peroxide value of a long-chain polyunsaturated fatty acid-containing fat comprising making a content of linoleic acid to 1 to 5 parts by weight and the total amount of the components (A) to 0.001 part by weight to 0.05 part by weight, on the basis of 1 part by weight of the content of the long-chain polyunsaturated fatty acid having 5 or more double bonds in the constituent fatty acid composition.
