れている。2. Description of the Related Art Edible vegetables, especially radishes, carrots,
Soft tissue food materials such as potatoes and seafood, especially cut white fish, are cut into appropriate sizes and shapes regardless of the home, restaurant, or food sales industry, and sugar, soy sauce, salt, etc. are added to the broth. The food is softly seasoned and cooked by heating and cooking by steaming / boiling. The food material naturally loses its shape, that is, "boiled".

よつて調理に要する加熱時間を短縮できるのである。The fact that ionized water softens plant fibers and proteins can be understood not only theoretically, but also from the performance, action and effect of water by the water conditioner and the electrodialysis method. As a result, the heating time required for cooking can be reduced.

能によつて煮崩れが防止される。Originally, chitosan has heat resistance and is hardly soluble in water. When impregnated with a chitosan solution or coated with a chitosan solution, the soft tissue food material withstands high heat during heating and cooking, and maintains its structure. When a food material previously impregnated with ionized water is treated with a chitosan solution, the material is sufficiently softened by the effect of the ionized water remaining in the material, but the ionized water neutralizes chitosan, making it less soluble in water. Its performance prevents boiling collapse.
