DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a packaged food and a method for producing the same, more specifically, it can be held in a hand or the like and easily eaten, and heated in a microwave oven, an oven or the like. The present invention relates to a wrapped food having a roasted potato-like image suitable for fast foods and snack foods that does not burst, and a manufacturing method thereof.

[Conventional technology and its problems]

In Japan, in recent years, the restaurant industry, in particular, fast food restaurants and convenience stores having simple range facilities have grown remarkably due to their fashionability and convenience.

On the other hand, sweet potato baked is a popular flavor because of its unique flavor and can be easily held by holding it with hands, and in that sense, it can be said that it is a food suitable for fast food and snack food.

However, since the sweet potato uses natural sweet potato as it is, the shape and weight are not uniform, and it is unsuitable as a product for fast food restaurants and convenience stores whose unit price is fixed.

In addition, sugar, butter, egg yolk, etc. are added to the sweet potatoes that have been cooked by heating and processed into so-called sued potatoes,
Foods with a roasted potato-like image have also been devised, which are produced by applying egg yolk or the like after forming and baking, or stuffing sweet potatoes into the remaining cuticles of the heat-treated sweet potato.

However, the one baked with egg yolk or the like lacks the image of a baked potato peel that peels off like a film, and when the contents of heat-treated sweet potato are stuffed into the remaining cuticle, the sweet potato Hollowing out the contents of
The work of filling the epidermis was complicated, and the shape and weight were not always constant.

It is desirable to heat such foods immediately before eating, but foods in which various filling materials are wrapped in conventional film foods (gyoza, spring rolls, etc.) are fried in oil or baked for a considerable time. Because of the need, it was unsuitable for fast food restaurants and convenience stores, where the time between placing an order and placing the product in front of that person is believed to be 25-60 seconds.

Under such circumstances, the cooked filling material wrapped with heat-treated film-like food is stored by a storage means such as freezing, and thawed, heated, or baked by a microwave oven or an oven when necessary. Although it is also considered to be served as a snack food, fast food that needs to be eaten easily by hand because the film-like food is broken by the steam generated from the filling during heating and baking processing and the filling easily pops out. Is not desirable.

Therefore, the object of the present invention can be easily held and held by hand, and the filling does not jump out even when heated in a microwave oven or oven, and can be easily manufactured with a uniform shape and weight. The purpose is to provide a packaged food with a potato-like image, which is particularly suitable for fast food and snack food.
