  The present invention has been made in view of the above circumstances, and its purpose is to provide a light texture immediately after cooking that is lost due to residual moisture in food or moisture transfer from the surrounding environment over time after cooking. An object of the present invention is to provide a fried food modifier, a premix for fried food containing the same, and a fried food that can be sustained for a long time.

As a result of extensive research by the present inventors, a fried food modifier obtained by spray-drying a dispersion in which a sucrose fatty acid ester having a specific composition and a saccharide is dispersed in water is not only immediately after cooking, but also long. It has been found that a light texture can be maintained for a long period of time, and the present invention has been completed.
That is, the present invention is a fried food obtained by spray-drying a dispersion containing (A) a sucrose fatty acid ester and (B) a saccharide that satisfy the following conditions (a) and (b): It is the first gist that it is a modifying agent.
(A) The fatty acid is a saturated fatty acid having 14 to 22 carbon atoms and / or an unsaturated fatty acid.
(B) The ester composition is such that the monoester is more than 0% by weight and not more than 40% by weight, the diester is not less than 5% by weight and less than 100% by weight, the triester is more than 0% by weight and not more than 40% by weight, Polyester is more than 0% by weight and 15% by weight or less.
The fried food modifier of the present invention preferably comprises 5 to 80% by weight of component (A) and 95 to 20% by weight of component (B).
Moreover, this invention makes the 2nd summary the fried food characterized by including 0.01-5 weight% of said modifier for fried food in the dough whole quantity before cooking.
Furthermore, this invention makes the 3rd summary the premix for fried food characterized by including 0.01-5 weight% of said modifier for fried food with respect to 100 weight% of wheat flour.

  According to the present invention, it is possible to provide a modifier having an effect of improving the texture of fried foods and maintaining the texture. That is, it is possible to prevent a fried food from becoming a crispy or crispy hard texture after cooking, provide a crispy or crispy light texture, and further provide a modifier that can maintain this texture for a long time. It has become possible.

  In addition, since the modifier of the present invention can be easily dispersed in cold water, it is not necessary to disperse in water after heating as in the case of existing modifiers, and its function is impaired even when powdered with flour. It is expressed without being easily handled.

Next, the form for implementing this invention is demonstrated.

The fried food modifier of the present invention is obtained by spray-drying a dispersion liquid containing a sucrose fatty acid ester and a saccharide that satisfy specific conditions.
The sucrose fatty acid ester of the present invention satisfies the following conditions (a) and (b).
(A) The fatty acid is a saturated fatty acid having 14 to 22 carbon atoms and / or an unsaturated fatty acid.
(B) The ester composition is such that the monoester is more than 0% by weight and not more than 40% by weight, the diester is not less than 5% by weight and less than 100% by weight, the triester is more than 0% by weight and not more than 40% by weight, Polyester is more than 0% by weight and 15% by weight or less.
The fatty acid constituting the sucrose fatty acid of the present invention has 14 to 22 carbon atoms, but 16 to 18 carbon atoms are preferable in terms of performance, little influence on taste, and easy availability. If the number of carbon atoms is less than 14, it becomes more hydrophilic and the texture cannot be sufficiently maintained, and it may affect the taste. If it exceeds 22, the food becomes more lipophilic. Industrialization becomes difficult due to the fact that the feeling cannot be maintained sufficiently and the raw material costs are high. The ester composition of the sucrose fatty acid of the present invention is such that the monoester is more than 0% by weight and 40% by weight or less, the diester is 5% by weight to less than 100% by weight, the triester is more than 0% by weight and less than 40% by weight, tetra The amount of the ester or higher polyester is more than 0% by weight and 15% by weight or less. Preferably, the monoester is 20% by weight to 30% by weight, the diester is 30% by weight to 60% by weight, and the triester is 15% by weight. % To 30% by weight, and the tetraester or more polyester is more than 0% by weight and 10% by weight or less. When the ester composition is out of the above range, for example, if there are too many monoesters, the hydrophilicity becomes high, and conversely, if there are too many triesters or polyesters, the lipophilicity becomes high, and in any case, maintaining the texture The original performance is not demonstrated. In addition, for example, when the diester content is 60% or more, the performance of the present modifier is further enhanced, but advanced purification is required, resulting in excessive production costs, which may cause cost restrictions in actual use. There is.

  The mechanism by which the sucrose fatty acid ester of the present invention gives a light and crisp texture to fried foods is not clear but can be estimated as follows.

  That is, various components in the dough interact with sucrose fatty acid esters, and each component is more finely and uniformly dispersed in the dough. In addition, the sucrose fatty acid ester in the dough promotes the substitution of moisture and frying oil during oil dripping and quickly reduces moisture. Furthermore, the surface tension of air and water is reduced by the addition of sucrose fatty acid ester, and fine bubbles are formed in the dough by the stirring operation. As a result, the dough structure after oiling becomes porous. In addition, sucrose fatty acid esters are generally known to interact with gluten and starch, and are thought to densify the gluten network and affect starch gelatinization and aging. It is considered that the above effects act in combination, and the fried food containing sucrose fatty acid ester shows a light texture after cooking.

  Although (B) saccharides used for the fried food modifier of the present invention are not particularly limited, specific examples include monosaccharides, disaccharides, polysaccharides, and sugar alcohols. These may be used alone or in combination of two or more. Specifically, examples of the monosaccharide include glucose, fructose, and galactose. Examples of disaccharides include sucrose, lactose, trehalose, and maltose. Examples of polysaccharides include dextrin, starch, and pectin, and examples of sugar alcohols include sorbitol, xylitol, and maltose. In addition, the above-mentioned starch contains the decomposition product. That is, examples of the starch include wheat starch, potato starch, corn starch, and tapioca starch, and the starch degradation product is the above-mentioned starch hydrolyzate. Wet heat starch can also be used. Of the saccharides, dextrin (DE = 2 to 30%) is preferable in that it is relatively inexpensive and easily available and has little influence on taste.

The blending ratio of the component (A) sucrose fatty acid ester and the component (B) saccharide of the fried food modifier of the present invention is not particularly limited, but the component (A) is 5 to 80% by weight and the component (B) is 20 It is preferably -95% by weight for obtaining good dispersibility in cold water. More preferably, the component (A) is 10% by weight to 60% by weight, and the component (B) is 40% by weight to 90% by weight.
When component (A) is less than 5% by weight, there is a possibility that the amount added to food increases because there are few active ingredients, and when it is 80% by weight or more, dispersibility in cold water or the like is not good, and spray drying May also be difficult.

 The modifier of this invention is manufactured from the process of adjusting the dispersion liquid by which (A) sucrose fatty acid ester and (B) saccharide | sugar are mix | blended, and the process of spray-drying this dispersion liquid.

  The dispersion of the present invention is prepared by mixing (A) sucrose fatty acid ester, (B) saccharide and water to prepare these aqueous dispersions. Specifically, from 100 parts by weight of (A) sucrose fatty acid ester and (B) total amount of saccharide (solid content), 100 parts of water (the total amount of the solids is 50%) to 900 parts (the total amount of solids). For 10 minutes) and stirring and mixing until a stable dispersion is obtained. Stirring can be performed by ordinary stirring means such as a homomixer (disper blade).

  The spray drying step of the present invention can be carried out by a conventionally known method, but it is preferable to dry under the conditions of an intake temperature of 90 to 200 ° C., an exhaust temperature of 50 to 100 ° C., and an atomizer rotational speed of 12000 to 20000 rpm. The modifier of the present invention is obtained through a step of spray drying. Even if (A) sucrose fatty acid ester and (B) saccharide are mixed and used in the form of powder, the modifier of the present invention is used. Such effects cannot be obtained.

  The fried food of the present invention contains 0.01 to 5% by weight of the above modifier in the total amount of dough before cooking. If the blending ratio of the modifier is less than 0.01% by weight, there is a problem that a sufficient reforming effect cannot be obtained. If the blending ratio is 5% by weight or more, the effect reaches its peak and the cost increases, resulting in an economical disadvantage. There is also a risk of profit. A more preferable range is 0.1 to 3% by weight.

  The premix for fried food of the present invention contains the above modifier in an amount of 0.01 to 5% by weight based on 100% by weight of wheat flour. If the blending ratio of the modifier is less than 0.01% by weight, there is a problem in that the performance is not exhibited. If the blending ratio is 5% by weight or more, the effect reaches a peak and only the cost increases. A more preferable range is 0.1 to 3% by weight.
