Description

本発明は穀類加工食品のほぐれ改良に関するものであり、詳しくは、麺類、米飯類等の穀類加工食品のほぐれ改良剤、およびこの改良剤を用いることによりほぐれ性の改良された穀類加工食品に関する。   TECHNICAL FIELD The present invention relates to an improvement in loosening of processed cereal foods, and more particularly to a loosening improver for processed cereal foods such as noodles and cooked rice, and a processed cereal food having improved looseness by using this improver.

近年の食の多様化により、加工食品のニーズが増大している。特に麺、米飯といった穀類食品は、大量に加工・調理された製品が、コンビニエンスストア、スーパーマーケットなどで販売され、多くの消費者に食されるようになってきた。   With the recent diversification of food, the need for processed foods is increasing. 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.

これら流通・市販される加工食品において、特に問題となるのが加工の利便性と時間の経過による品質劣化である。   Among these processed foods that are distributed and marketed, the problems that are particularly problematic are the convenience of processing and the deterioration of quality over time.

麺、米飯等の穀類加工食品は一般に澱粉を含んでおり、加工・調理の際、食品表面に澱粉質が流出し、食品同士が結着してしまう。その結果、麺製品であれば、麺同士の付着により、一食分に小分けしたり、喫食時に汁やソースと混ぜたりすることが困難になる。即席麺の場合は、麺が結着した部分が湯戻りしにくくなる。また、米飯製品の場合、チャーハンで全体が均一に炒められない、おにぎりの成型機で飯粒がつぶれてしまうということが起こる。こういった問題は、生産効率の低下、コストアップを招き、さらに、できあがった食品も喫食時に食べ辛く、美味しくないという結果を招く。   Processed cereal foods such as noodles and cooked rice generally contain starch, and during processing / 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 a problem leads to a decrease in production efficiency and an increase in cost, and also results in that the finished food is difficult to eat at the time of eating and is not delicious.

この食品同士の結着性をなくし、ほぐれ性を改善する従来の方法としては、油脂または乳化油脂を混合する方法があるが(特許文献1)、油脂をほぐれ剤に使用すると、喫食時につゆに油浮きが発生し、素麺やそば、うどんのような麺類にも使用できない。その他、HLBの高いショ糖脂肪酸エステルを添加する方法(特許文献2)、有機酸を添加する方法(特許文献3)、機械的な振動を与えながら加工する方法、水溶性ヘミセルロースを使用する方法(特許文献4)などがあるが、いずれも十分なほぐれ性を得られず、また乳化剤単独の使用では食感が悪くなるといった問題がある。   As a conventional method for eliminating the binding property between the foods and improving the looseness, there is a method of mixing fats or emulsified fats and oils (Patent Document 1). Oil float occurs and can not be used for noodles such as raw noodles, buckwheat noodles and udon. In addition, 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 processing while applying mechanical vibration, a method of using water-soluble hemicellulose ( Patent Document 4) and the like, but none of them can provide sufficient loosening properties, and the use of an emulsifier alone has a problem of poor texture.

ほぐれ効果を付与するのにはレシチンが一般的に良く知られているが、他素材との反応性が高いため、製剤として組み合わせて使用することが困難な素材である。例えば、水溶性ヘミセルロースのほぐれ性を改良するためにレシチンと併用すると、相互作用により凝集する問題を有している(特許文献5)。   Lecithin is generally well known for imparting a loosening effect, but it is a material that is difficult to use in combination because it has high reactivity with other materials. For example, when used together with lecithin to improve the looseness of water-soluble hemicellulose, there is a problem of aggregation due to interaction (Patent Document 5).

It was. Specifically, an object was to formulate a water-soluble hemicellulose and lecithin having a strong fraying improving action in a solution state without agglomeration and use them as a fraying improving agent.

As a result, there is provided a loosening improver for processed cereal foods using a polyglycerol fatty acid ester having a degree of polymerization of glycerol of 4 or more in addition to water-soluble hemicellulose and lecithin. The present inventors have found that the agglomeration in a solution state does not occur and that the looseness of the processed cereal food can be improved by adding the loosening improver, and the present invention has been completed.

(Noodle loosening evaluation method)
For each loosening improver, the looseness of the noodles was evaluated.
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 panelist evaluated with 1-5 points based on the standard of Table 1, and made the average score the looseness evaluation. If the average score was 4 or more, it was judged that the looseness was good.
