Title:
STABILIZED TOCOPHEROL-CONTAINING OIL AND FAT COMPOSITION
Document Type and Number:
Japanese Patent JP3390555
Kind Code:
B2
Abstract:
PURPOSE: To suppress loss of α- and β-tocopherol by heating and cooking and to stabilize a tocopherol-containing fat and oil composition by existence of specific amounts of a phospholipid and a diglyceride.
CONSTITUTION: An oil and fat composition is mixed with 0.01-10wt.% (preferably 0.1-5wt.%) of a phospholipid and 5-60wt.% (preferably 5-30wt.%) of a diglyceride and the content of α- and β-tocopherol is adjusted to 0.05-2wt.% (preferably 0.01-0.5wt.%) by adding vitamin E. α- and β-tocopherol having high physiological activity are slightly decomposed and lost by heating and cooking. The example of the phospholipid includes preferably a mixture of phospholipids of formula I and formula II (A1 and A2 are each independently H, a 8-24C saturated or unsaturated aliphatic acyl; R1 and R2 are each independently a 8-24C saturated or unsaturated aliphatic acyl; X1 is an inositol residue; X2 is H or an alkali metal; X3 is a choline residue; X4 is H or ammonium) (the former contains a nitrogen atom and the latter contains a nitrogen atom).
