2. Description of the Related Art Various types of bread are known, such as bread and confectionery bread, but in recent years, a bread having a soft texture has been demanded, which has become a kind of boom. To impart a soft texture to bread, edible oils, enzymes, and
Improvements have been made by adding starch, emulsifiers, etc. and baking, and some effects have been obtained for softening bread. On the other hand, even if the bread is soft immediately after the bread is manufactured, the value of the product is reduced if the bread is aged and hardened over time. In particular, recently, chilled distribution is being carried out, in which bread such as sandwiches is delivered while keeping it at a low temperature, but since the cooling temperature is in a temperature range that accelerates aging, how to prevent aging becomes an issue. There is.

Techniques for softening bread and preventing aging include, for example, a dough improving agent for bread making containing an oil and fat, a modified starch, and an emulsifier and emulsified into an oil-in-water type (JP-A-5-161446), Oil / fat composition consisting of plastic oil / fat having specific properties, organic acid monoglyceride, and enzyme (JP-A-3-292847), emulsifier in liquid crystal state, oil / fat mixture containing enzyme (JP-A-3-297345), glycerin fatty acid ester And other surfactants, enzymes,
Oil and fat composition containing a thickener (Japanese Patent Laid-Open No. 3-292848).
No.), an emulsifier, a starch and / or an oil / fat composition containing an enzyme (JP-A-4-207143), an oil phase containing a monoglyceride and a polyglycerin fatty acid ester in the oil phase and a sucrose fatty acid ester, an enzyme, a sugar and / or a sugar.

The method of using a fat mixture containing an emulsifier in a liquid crystal state and an enzyme is
In the method of adding fats and oils, a method of cooling and adding semi-fluid fats and oils and mixing them lightly is adopted, and it is not in a stable emulsified state, and it is easy to oil off when the temperature or external pressure changes, and there is a problem in stability . Glycerin fatty acid ester and other surfactants, enzymes, a method of using an oil and fat composition containing a thickener and a method of using an oil and fat composition containing an emulsifier, starch and or an enzyme, an enzyme or a thickener in the oil and fat. Since they are dispersed, they are coated with fats and oils, so that they do not act effectively on the bread dough. Further, a method of using an oil-in-water type emulsified oil and fat composition for bread making comprising an oil phase containing a monoglyceride and a polyglycerin fatty acid ester in the oil phase and an aqueous phase containing a sucrose fatty acid ester, an enzyme, a sugar and / or a sugar alcohol. Has a drawback that it improves the emulsion stability because it uses a polyglyceride but impairs the flavor of bread.

The oil-in-water emulsified oil / fat composition used in the present invention is obtained by adding an oil phase to an emulsifier phase to emulsify it, adding an aqueous phase thereto, mixing and quenching and kneading. The oil phase containing edible oil and fat and fatty acid monoglyceride is obtained by adding fatty acid monoglyceride to edible oil and fat heated to 65 to 75 ° C. and stirring at the same temperature for 30 minutes to 1 hour. By dissolving the fatty acid monoglyceride in the oil phase, an oil-in-water emulsified oil / fat composition that enhances the dispersibility of the fatty acid monoglyceride and imparts bread softening and antiaging effects can be obtained.

The amount of water used in the emulsifier phase is preferably 21 to 27% by weight. If the amount of water used is less than 21% by weight, the viscosity of the emulsifier phase becomes large and it becomes difficult to stir, and if it exceeds 27% by weight, the emulsified diameter becomes large. There is a risk of becoming unfavorable.

The aqueous phase is water containing α-amylase, starch,
Obtained by adding sugar alcohol and dissolving. The temperature of the water for preparing the aqueous phase may be room temperature or under heating, but it is preferably room temperature to prevent inactivation of α-amylase and gelatinization of starch. The amount of water used in the oil-in-water emulsion oil / fat composition of the present invention is 24 to 32.
Weight% is preferable, but the amount of water used for the water phase is
1-5% by weight is preferred. When the amount of water used in the aqueous phase is 1% by weight or less, the dispersibility of starch and enzyme becomes poor, and when it exceeds 5% by weight, the amount of water in the emulsifier phase decreases and the viscosity of the emulsion after addition of oil and fat increases and stirring It is difficult to do, which is not preferable.

Next, the oil phase is added to the emulsifier phase and emulsified to prepare an oil phase / emulsifier phase type emulsion. The temperature of the emulsifier phase during emulsification is preferably 60 to 70 ° C, and the temperature of the oil phase is preferably 65 to 75 ° C. Examples of the apparatus used for emulsification include an emulsification pot equipped with a stirrer (blades, homomixer) capable of heating with ordinary hot water.

An aqueous phase is added to the obtained oil phase / emulsifier phase type emulsion, mixed, and rapidly kneaded to obtain the oil-in-water emulsified oil / fat composition of the present invention. The oil-in-water emulsified oil / fat composition obtained is a composition in which the oil / fat is emulsified into uniform and small particles, and can be easily kneaded into the dough in a paste form to uniformly disperse the oil / fat into the dough, and the enzyme has an aqueous phase. Since it is present in the dough, the enzyme easily acts effectively in the dough. As a device for kneading and kneading after mixing, a device used for producing margarine such as a botter, a perfector, and a combinator can be used.

The oil-in-water emulsified oil / fat composition of the present invention is obtained as described above, but if necessary, other components such as β-carotene, dyes such as annatto dye, flavors such as milk flavor and butter flavor, etc. Can be added, and the addition amount of each is preferably less than 2% by weight.

The oil-in-water emulsified oil / fat composition of the present invention is added to bread dough and baked to obtain bread that is soft and has an antiaging effect. The amount of bread added to the dough is preferably 6 to 12% by weight. In addition, examples of bread suitable for using the oil-in-water emulsified oil / fat composition of the present invention include chilled distribution breads such as sandwiches, which are severely aged, raisin breads, frozen dough, confectionery breads and the like.
