Abstract
Description
本発明は、チルド冷蔵保管と再加熱によって、調理済み食品、特にご飯を加熱するのに好適に使用できる樹脂製食器に関する。さらに詳しくは、本発明は、特定の形状を有した調理済み食品の乾燥に好適な食器に関する。 The present invention relates to a resin tableware that can be suitably used for heating cooked food, particularly rice, by chilled refrigerated storage and reheating. More particularly, the present invention relates to a tableware suitable for drying cooked food having a specific shape.
学校、病院、企業内食堂などでは大量の食品が配膳されている。近年チルド冷蔵保管と再加熱の技術が大幅に改善されてきたことと、そのための機器の入手が容易になってきた(例えば特許文献1)ことから、食品を良好な環境で調理し、必要に応じて加熱して食事に供する方法が注目されるようになった。 A large amount of food is served in schools, hospitals, and company cafeterias. In recent years, chilled refrigerated storage and reheating technologies have been greatly improved, and the availability of equipment for that has become easier (for example, Patent Document 1). In response, the method of heating and serving meals has attracted attention.
このような調理済み食品を急速冷蔵して保管し、配膳前に再加熱して提供する方式は、クックチルシステムと呼ばれている。クックチルを使用すれば特殊な食品添加物を使用しなくとも、保管が可能であり、味のよい食品を暖かい状態で提供できるという利点がある。チルド冷蔵保管し、再加熱して食事に供するのに、調理済み食品を収容した食器をトレイ上に載置して、温風によって調理済みを加熱する方法が用いられている。 Such a system in which cooked foods are rapidly refrigerated and stored, and reheated before serving is provided, is called a cook chill system. Use of cook chill has the advantage that it can be stored without using any special food additive, and a tasty food can be provided in a warm state. In order to store chilled refrigerated food and reheat it for a meal, a method of placing cooked food on a tray and heating the cooked food with hot air is used.
ところが、冷蔵保管した調理済み食品を、食事に供するに際して温風によって再加熱するとき、食器に接触している部分の水分が蒸発してしまい、乾燥するという問題があった。調理済み食品の加熱を促進するために、蓋が調理済み食品と接触する構造の食器が提案されている(例えば特許文献2)が、提案されている食器を用いてもなお食器と接触する部分の乾燥を防ぐには十分ではなかった。特に調理済み食品がご飯であるとき、再加熱後のご飯の上面部周辺は、乾燥して食感及び食味が低下するため、喫食の楽しみ及び食欲がそがれるという問題があった。 However, when the cooked food that has been refrigerated is reheated with hot air when it is served, there is a problem that the moisture in the portion in contact with the tableware evaporates and dries. In order to promote the heating of the cooked food, a tableware having a structure in which the lid comes into contact with the cooked food has been proposed (for example, Patent Document 2), but the portion still in contact with the tableware using the proposed tableware It was not enough to prevent the drying of. In particular, when the cooked food is rice, the area around the top surface of the reheated rice is dried and the texture and taste are lowered, and there is a problem that the enjoyment of eating and the appetite are worsened.
本発明者は、前記従来技術の課題を解決するために食器形状の改良に鋭意努力した結果本発明に到達したものである。
