Activated clay was added in an amount of 1.5% by weight based on the weight of fat and oil, and decolorization was performed for 10 minutes under conditions of 110° C. and 1330 Pa while stirring. After decolorization, the fat and oil from which the activated clay was removed was deodorized for 90 minutes under the conditions of 250° C., 266 Pa, and 3% by weight of steam. After deodorizing, the glycidol fatty acid ester contained in the oil was analyzed.
- Example 2 Crude palm oil (CPO) preliminarily subjected to deacidification using alkali was subjected to a decolorization-deodorization process.

- Example 3 Crude palm oil (CPO) degummed with phosphoric acid was subjected to a decolorization-deodorization process.
- a 50% aqueous citric acid solution was added to CPO as a raw material in an amount of 0.1% by weight based on fat and oil.
- Activated clay was adjusted to 1.5% by weight based on fat and oil, and decolorization was performed for 10 minutes under the conditions of 110° C. and 1330 Pa. After decolorization, the fat and oil from which the activated clay was removed was deodorized for 90 minutes under the conditions of 250° C., 266 Pa, and 3% by weight of steam. After deodorizing, the glycidol fatty acid ester contained in the oil was analyzed.
- Table 2 shows the evaluation results of the fats and oils obtained in Examples 1-3 and Comparative Examples 1-3.
- Comparative Example 1 is a comparative example in which degumming was performed in the same manner as in Patent Documents 2 and 3, but because it did not satisfy the constitution of the present invention, the content of glycidol and glycidol fatty acid ester could not be reduced.
- oils and fats can be produced in which the contents of glycidol and glycidol fatty acid esters are reduced without impairing the flavor.
