Description

Fray improving agent for processed cereal foods

[Technical Field] The present invention relates to a fray improvement for processed cereal foods, and more particularly to a flaw improving agent for processed cereal foods such as noodles and cooked rice, and a processed cereal food having improved looseness by using this improver.

Demand for processed foods is increasing due to recent diversification of food. In particular, cereal foods such as noodles and cooked rice have been processed and cooked in large quantities and sold at convenience stores, supermarkets, etc., and have been eaten by many consumers.

These processed and marketed processed foods are particularly problematic in terms of processing convenience and quality deterioration over time.

Processed cereal foods such as noodles and cooked rice generally contain starch, and during processing and cooking, starch will flow out onto the surface of the food and the foods will be bound together. As a result, in the case of a noodle product, it becomes difficult to divide it into one serving due to adhesion between noodles or to mix with juice or sauce at the time of eating. In the case of instant noodles, the portion where the noodles are bound is less likely to return to hot water. In addition, in the case of cooked rice products, the whole rice cannot be fried uniformly with fried rice, and the rice grains are crushed by a rice ball molding machine. Such problems lead to a decrease in production efficiency and an increase in cost, and further, the resulting food is difficult to eat and is not delicious.

As a conventional method for eliminating the binding property between the foods and improving the looseness, a method of mixing oil or emulsified oil (Patent Document 1), a method of adding a sucrose fatty acid ester having a high HLB (Patent Document 2) ), A method of adding an organic acid (Patent Document 3), a method of using water-soluble hemicellulose (Patent Document 4), a method of using gum arabic, gati gum, and an emulsifier (Patent Document 5).

However, the techniques of Patent Documents 1 to 5 have a problem that a sufficient unraveling effect cannot be obtained, and there is also a problem that when using an emulsifier alone as in Patent Document 2, the texture becomes worse. Furthermore, depending on the material used, when the surface treatment was performed, the treatment liquid flowed with time, leading to deterioration of the loosening.
Therefore, the present invention suppresses quality deterioration such as deterioration of the looseness in storage than before, and a loosening improver for efficiently producing a delicious processed grain food and a processed grain food using the loosening improver. The purpose was to provide.

Hereinafter, the present invention will be further described with reference to examples, but the present invention is not limited to these examples. In the examples, both parts and% mean weight basis.

In the following examples, soybean-derived water-soluble soybean hemicellulose, which is commercially available as “Soya Five Boo S” (manufactured by Fuji Oil Co., Ltd.), was used as the bean-derived water-soluble hemicellulose.

(Examination of surface treatment solution viscosity) (Examples 1 to 4, Comparative Examples 1 to 4)
Based on the formulation shown in Table 1, water-soluble soybean hemicellulose and guar gum (SUPERGEL CSA: manufactured by Sanki Co., Ltd.) were added to water and then dissolved by heating to prepare loosening improvers A to H.
The noodles were evaluated for their looseness.
First, 600 g of strong powder, 400 g of buckwheat flour, 10 g of salt and 300 g of water were mixed, kneaded with a mixer for 15 minutes, and rolled and cut out (incision # 22 corner, noodle string thickness 1.3 mm) according to a conventional method. The noodles were boiled in boiling water for 3 minutes, washed with running water for 30 seconds to obtain boiled noodles. Next, 6 g of each loosening improver was sprayed uniformly per 200 g of boiled noodles, filled in a container and sealed, and the looseness after refrigerated storage for 1 day was evaluated by 10 panelists. Each panel was evaluated with 1 to 5 points based on the criteria shown in Table 2, and the average score was set as a looseness evaluation. If the average score was 4 or more, it was judged that the looseness was good. Moreover, when performing surface treatment, the thing which can be processed easily and uniformly was set as (circle), and the thing which is difficult to make uniform was set as x. The above evaluation results are shown in Table 1.

(Table 1) Recipe (%) and results of looseness evaluation

(Table 2) Evaluation criteria for looseness

As the viscosity increased with the addition of guar gum, the looseness improved dramatically. However, when the viscosity is too high, it becomes difficult to uniformly treat the noodles, and workability is reduced. Even when only guar gum was dissolved and surface-treated, the looseness of the noodles was not obtained.

(Type of thickener) (Examples 5 to 8)
Next, surface treatment was performed using various thickeners. Based on the formulation of Table 3, water-soluble soybean hemicellulose and various thickeners were added to water and then dissolved by heating to prepare loosening improvers IL. “Bistop D-2050” (manufactured by Saneigen FFI Co., Ltd.) for locust bean gum, “San Ace” (manufactured by Saneigen FFI Co., Ltd.) for xanthan gum, and Serogen F for carboxymethylcellulose -SB (Daiichi Kogyo Seiyaku Co., Ltd.) and pectin used were GENU pectin type YM-150-LJ (Sanki Co., Ltd.). The looseness was evaluated in the same manner as in Example 1. The evaluation results are shown in Table 3.

(Table 3) Recipe (%) and results of looseness evaluation

From the results of Examples 5 to 8, it was confirmed that the looseness of the noodles was also improved when locust bean gum, xanthan gum, carboxymethylcellulose or pectin was used as a thickener other than guar gum.

(Evaluation of looseness of instant noodles) (Example 9, Comparative Example 5)
Semi-strong powder 600g, starch 67g, salt 10g, sodium carbonate 1g, potassium carbonate 1g, water 230g, kneaded for 15 minutes with a mixer, rolled and cut (cutting teeth # 22, noodle string thickness 1.7mm) according to conventional methods. The noodles obtained were steamed as 80 g per egg to prepare Chinese noodles.
Next, according to the composition shown in Table 5, 5% of the loosening improver D was added to the noodles, and after entangled with the noodles, they were dried at 80 ° C. for 1 hour to prepare instant noodles. 400 g of hot water was added to 1 ball of instant noodles obtained and reheated for 8 minutes, and the looseness was evaluated in three stages: ○: unraveled, Δ: difficult to unravel, x: unraveled. Table 4 shows the evaluation results of the looseness.

(Table 4) Recipe (parts) and results of looseness evaluation

As shown in Table 4, the instant noodles to which the present loosening improver of Example 9 was added had good loosening properties after reconstitution with hot water.

(Evaluation of looseness of cooked rice) (Example 10, Comparative Example 6)
500 g of Koshihikari was thoroughly boiled with water and soaked for 1 hour, then watered so that the total amount of water became 600 g, and rice was cooked using a household rice cooker. A comparative example 6 was prepared by adding 25 g of water to the cooked rice, mixing until uniform and allowing to cool to room temperature. In Comparative Example 6, Example 10 was obtained by the same treatment except that the loosening improver solution D was added to the cooked rice. Compared with Comparative Example 6, the looseness of the rice of Example 10 was significantly improved.
