PROBLEM TO BE SOLVED: To solve the problem wherein since a microwave oven takes water heating system, water contained in food material becomes vapor and escapes above 100°C, and even if high temperature is attained taking much time, the food material becomes dry, when potato is heated, the water content is lowered to remarkably impair texture and also there is the danger that an egg ruptures, then the microwave oven is required to achieve delicious, good texture, sanitary and safe high temperature cooking.SOLUTION: When a food material is heated in the simple construction of covering with metallic silicon of porous structure in a heating vessel by the microwave oven, the metallic silicon becomes high temperature above 200°C or more in a short time, so that although the covered food material becomes high temperature, the moisture is kept and amplified 80% or more and the food material is evenly heated, resulting in texture improvement. Thus, in the roast sweet potato, moisture is kept at high temperature and texture is not impaired. No rupture of husk of the egg occurs. The metallic silicon has high hardness so that it does not wear and it has long life, it does not contain heavy metal, and it has sterilizing action to destructive fungus. Thus, high temperature, short time and efficiently safe cooking method in the microwave oven can be achieved.COPYRIGHT: (C)2013,JPO&INPIT【課題】電子レンジは水分加熱方式の為100度以上になると食材に含まれる水分が蒸気となり逃げ出す、又時間をかけて高熱にしても食材は乾燥状態になる。芋を加熱すると含水率が下がり食感が著しく損なわれる。また卵も破裂するなど危険である。電子レンジでの美味しいかつ食感が良い衛生的にも安全な高熱調理が求められている。【解決手段】加熱容器の中で食材を多孔質構造の金属シリコンの粒子で覆う単純な構成で電子レンジ加熱すると、金属シリコンが短時間で200度以上の高熱になり、覆われた食材も高熱となるが水分が80%以上に保持増幅され均等に加熱されることで食感が著しく良くなった。高熱で水分が保持され食感を損なわない焼き芋が可能となった。卵も殻の破裂が無くなった。また金属シリコンは硬度が高く磨耗せず長寿命、重金属を含まず有害菌に対する除菌作用があることで併せて電子レンジでの高熱かつ短時間で効率的安全な調理法を実現した。【選択図】図1
