Abstract: The present invention addresses the problem of providing a method for producing a flavor oil having a burnt cheese flavor, said flavor oil being capable of imparting a roasted cheese-like fragrant flavor or enhancing a cheese flavor when just used in cooking. The present inventor found that a flavor oil having a fragrant burnt cheese flavor can be obtained by a production method that comprises heating an oil in the presence of 3-20 mass %, relative to the oil, of a starting material derived from cheese. In particular, a stronger and better flavor could be obtained by using a cheese powder and conducting the heating in a reaction system purged with an inert gas.

Abstract: A roll-in oil and fat composition is prepared, in which 45 to 95% by weight of transesterified oils and fats, 5 to 25% by weight of a liquid oil, and less than 1% by weight of high-melting point oils and fats are contained in an oily phase, wherein the transesterified oils and fats have a lauric acid content of 5 to 25% by weight, a palmitic acid content of 5 to 25% by weight, and a stearic acid content of 10 to 35% by weight all relative to the total content of all of constituent fatty acids and have a stearic acid-to-palmitic acid weight ratio of 0.5 to 7, and the high-melting point oils and fats have an open-tubed melting point of higher than 45° C. Layered bakery food is produced using the roll-in oil and fat composition.
