Description

The present invention relates to a transesterified oil and fat and a roll-in oil and fat composition using the same. Specifically, the present invention relates to a roll-in oil and fat composition having a wide temperature tolerance and good workability.
Furthermore, it is related with the layered bakery food which can maintain a good crispness and a crisp feeling.

Layered bakery foods such as pies and Danish pastries form a layered structure by rolling a roll-in oil / fat composition into dough and folding it. Layered bakery foods have a distinctive texture due to this layered structure. Recently, laminar bakery foods that are crisp and crunchy have been favored even in wholesale, including oven fresh bakery. .
In order to provide a layered bakery food that has a good crispness and a crisp feeling, it is common to set various types of oil-in compositions for roll-in and baking conditions.

For example, it is known that the amount of crystals in the oil composition for roll-in greatly affects the texture of the layered bakery food. If the amount of crystals in the oil composition for roll-in is small, the oil composition for roll-in in the dough If the amount of crystal is too large and the amount of crystals is too large, the oil composition for roll-in will break in the dough during rolling, resulting in insufficient layer formation, resulting in good crispness and crispy feeling. Absent. Therefore, adjusting the amount of crystals of the oil-in composition for roll-in can be mentioned.
On the other hand, in transesterified oils and fats, as a technique that focuses on the ratio of saturated fatty acid residues having 14 or less carbon atoms and the ratio of saturated fatty acid residues having 20 or more carbon atoms to all fatty acid residues constituting all triglycerides, patents References 1-3 can be mentioned.

Patent Document 1 describes an oil / fat composition comprising a random transesterified oil / fat of an oil / fat blend containing 2 to 50% saturated fatty acid having 14 or less carbon atoms and 1 to 50% saturated fatty acid having 20 or more carbon atoms. Patent Document 1 has no description of the content of palmitic acid in the oil / fat blend, and the content of palmitic acid in the oil / fat blend of the Examples of Patent Document 1 is outside the scope of the invention.
In Patent Document 2, 5 to 15% by weight of liquid oil, behenic acid or an ester thereof, or a fat and oil containing them, and oils derived from palm oil and lauric oils and fats are treated with 1,3-specific lipase. And a method for producing a hard stock characterized in that the transesterification is carried out selectively.
Further, in Patent Document 3, the constituent fatty acid content is 12 to 17% by weight of saturated fatty acid having 12 or less carbon atoms, 30 to 65% by weight of saturated fatty acid having 14 or more carbon atoms, and 2% by weight or less of saturated fatty acid having 20 or more carbon atoms. An oil / fat composition obtained by random transesterification of a certain oil / fat mixture and further hydrogenation is described.

  The oil and fat composition for roll-in manufactured using the oil and fat obtained in Patent Documents 1 to 3 above has extensibility in a wide temperature range from a low temperature to a high temperature required for the oil and fat composition for roll-in. In addition, the layered bakery food using the oil and fat composition for roll-in produced using the oil and fat obtained in Patent Documents 1 to 3 cannot obtain good crispness and crispy feeling.

  Accordingly, an object of the present invention is to have a wide temperature tolerance (it does not become extremely hard or soft in a wide temperature range, and has the stiffness and extensibility necessary for a roll-in fat and oil). It is an object to provide a transesterified oil and fat that can provide a product. Furthermore, it aims at providing the layered bakery food which has favorable crispness and a crispy feeling by using the oil-fat composition for roll-ins using said transesterified oil and fat for a layered bakery food.

Random esters of fats and oils containing 31-37% by weight of groups, 2.5-5.5% by weight of behenic acid residues, and 53-67% by weight of saturated fatty acid residues The above-described object is achieved by the transesterified oil and fat exchanged.

Since the oil-fat composition for roll-in using the transesterified oil / fat of the present invention has a wide temperature tolerance, the workability is good.
Moreover, the layered bakery product using the oil-in-fat composition for roll-in using the transesterified oil / fat of the present invention can have good crispness and crispness.

Hereinafter, it demonstrates in detail based on preferable embodiment of the transesterified fats and oils of this invention.

  The oil-in composition for roll-in using the transesterified oil and fat obtained when the ratio which the lauric acid residue accounts is less than 9 mass% among all the fatty acid residues which comprise all the triglycerides in said oil-and-fat composition is hard It is not preferable because it cannot have a wide temperature tolerance, and if it is more than 15% by mass, the oil composition for roll-in using the obtained transesterified fat becomes soft and cannot have a wide temperature tolerance. Therefore, it is not preferable.

  When the proportion of palmitic acid residues is less than 31% by mass of all fatty acid residues constituting all triglycerides in the above oil and fat composition, an oil and fat composition for roll-in using the obtained transesterified oil and fat is obtained.

  When the proportion of saturated fatty acid residues is less than 53% by mass of the total fatty acid residues constituting all triglycerides in the above oil and fat blend, the roll-in oil and fat composition becomes soft and has a wide temperature tolerance. This is not preferable because it cannot be carried out, and if it exceeds 67% by mass, the oil-in-fat composition for roll-in becomes hard and cannot have a wide temperature tolerance, which is not preferable.

  The ratio of the lauric acid residue in the total fatty acid residues constituting the total triglyceride in the oil / fat blend is preferably 10 to 14% by mass, more preferably 10 to 13% by mass, and most preferably 12 to 12%. 5% by mass.
