Oil-and-fat composition
The present invention addresses the problem of providing an ascorbic acid-containing oil and fat that allows improvement of ascorbic acid content in the ascorbic acid-containing oil and fat and that can be used for a variety of food items. In this oil-and-fat composition, an appropriate amount of ascorbic acid is contained, and the ascorbic acid is contained as an aqueous solution having a pH of 2.5-5.3.
1 . A method for producing a fat composition, the method comprising mixing an oil phase and an aqueous phase, wherein a pH of the aqueous phase is adjusted to 3.5 to 5.3, wherein the aqueous phase is an aqueous solution comprising an ascorbic acid in an amount of 50 to 50,000 mass ppm as an ascorbic acid equivalent relative to the oil phase, and wherein the oil phase comprises glycerin, wherein the aqueous phase is dispersed in the oil phase, and wherein the fat composition is edible.
2 . The method according to claim 1 , wherein the amount of ascorbic acid is 100 to 40,000 mass ppm as ascorbic acid equivalent, and wherein an amount of water is adjusted to 0.5 to 2.0 times the amount of the ascorbic acid.
3 . The method according to claim 1 , wherein the oil phase further comprises an oil-soluble emulsifier.
4 . The method according to claim 3 , wherein the oil phase comprises the glycerin in an amount of 0.3 to 5 times the amount of the ascorbic acid.
5 . The method according to claim 2 , wherein the oil phase further comprises an oil-soluble emulsifier.
6 . The method according to claim 5 , wherein the oil phase comprises the glycerin in an amount of 0.3 to 5 times the amount of the ascorbic acid.
