Description

  The present invention mainly relates to a method for cooking frozen foods, and relates to a technique for heating and cooking frozen foods using a microwave oven.

  In recent years, with the development of freezing technology, various frozen foods have been developed and sold. These frozen foods are roughly classified into pre-cooked foods and cooked foods. Typical foods before cooking include “fried food” such as croquettes and fried shrimp, which are frozen by processing bread and crumbs on raw or primary processed foods. The cooking is completed by frying it with oil in a tempura pan as it is frozen, and it can be served on the table. In addition, cooking “baked goods” such as hamburgers is completed by baking them in a frying pan while frozen. Thus, the food before cooking leaves the final stage of cooking to the consumer, and has to be fried and baked. That is, a pan and a frying pan were prepared, a large amount of oil was required, and the kitchen area was soiled. In particular, it was not suitable for a small amount of cooking for one person.

  On the other hand, cooked foods are mainly cooked using a microwave oven or the like, but these have been the subject of reheating rather than cooking. Therefore, for example, when chicken and vegetables are alternately skewered and baked, such as yakitori, and frozen once, meat juice etc. will flow out due to the occurrence of so-called drip when thawing or heating with a microwave oven, However, it was difficult to obtain a texture similar to that baked in an open fire.

  Thus, recently, raw foods are also cooked in a microwave oven. For example, Patent Document 1 proposes a food set in which ingredients and seasonings are mixed in the same package and cooked in a microwave oven and a cooking method thereof.

JP-A-2005-350109

  However, although the food set and cooking method disclosed in this document are suitable for “boiled” dishes, they cannot be applied with “grilled eyes” like yakitori and hamburgers, so the range of foods that can be used is limited. It was done.

  Therefore, in the present invention, it is an object to disclose a cooking method for cooking a food with a surface baked, such as a yakitori or a hamburger, in a frozen food, and in particular, there is no outflow of drip from the food during cooking. It is designed to provide food with a texture.

In order to solve the above-described problems, the present invention provides a pretreatment process for processing raw food as a method for cooking frozen food, and a surface of the pretreated food without heating up to the inside. A freezing step for freezing the freezing material, a freezing step for freezing the freezing food material, and a function of maintaining the water vapor atmosphere in the container constant in a sealed container of a predetermined size. A means of comprising a thawing / cooking process of heating in a microwave oven in a heating container was adopted.

  Then, a means for forming the burned line on the food material radiantly by a burner or directly by a heated iron plate or the like was adopted.

  In addition, the heating container includes a container having a predetermined depth and a lid that is hermetically fitted to the container, and a means is adopted in which a pressure adjusting unit is provided on the lid.

In addition, the frozen food is processed into a form suitable for eating raw food, and the food that has been frozen after the surface has been burned without heating to the inside, and the food is stored and heated in a microwave oven At times, a means of comprising a heating vessel having a function of maintaining a constant water vapor atmosphere in the vessel was adopted.

  According to the method of the present invention, since the surface of the food material is pre-baked before the freezing step, the umami is confined in the food material, and the umami and nutrients do not flow out as a drip during thawing and cooking. The effect is obtained. In addition, since the frozen food is cooked in a sealed container having a constant water vapor atmosphere, moisture does not evaporate from the food and can be cooked as a juicy and baked food. It became so.

  In addition, since the heating container is provided with a pressure control unit, a steam atmosphere at a constant pressure is maintained in the container when heated by a microwave oven, and cooking can be performed like freshly baked without drying the frozen food. Is.

  On the other hand, frozen food is made up of foods that have been baked in advance and a heating container that has a function of maintaining a constant water vapor atmosphere in the container when heated in a microwave oven. In addition, food that can be cooked in earnest can be provided.

  Hereinafter, preferred embodiments of a method for cooking frozen food according to the present invention will be described. FIG. 1 is a flowchart showing an outline of the steps of the method of the present invention. Here, an example of cooking yakitori will be described, but the present invention is not limited to this example. For example, it can be applied to a wide variety of foods with savory eyes such as hamburger, beef steak, dumplings, and grilled salmon.

  In FIG. 1, S1 is a pre-processing step, and in a yakitori, it is a step of preparing chicken, which is a food material, by cutting it into an appropriate size and alternately staking it with vegetables such as leeks. If necessary, the sauce may be applied or dipped in the sauce. This process includes various elements depending on the ingredients, and cuts the ingredients into a predetermined size, seasonings, kneads multiple ingredients, etc. It includes a process.

  S2 is a baking process, and is used to burn the pretreated food surface. In other words, a burned line is formed on the surface of the food material by an appropriate heating means, and the inside is not heated and the inside remains raw. As a heating means, there are a case where a burner or the like is used to form a burned line, and a case where a foodstuff is directly brought into contact with an iron plate heated to a high temperature to form a burned line. In either case, the surface of the food material is burned by heating at a high temperature in a short time. This grilling is done so that when cooking with a microwave oven as described below, the meat juice is confined in the ingredients, so that the same taste and texture as when processing raw foods can be obtained. belongs to.

  Next, S3 is a freezing process, and the baked food is frozen by a conventionally known freezing / chilling method. As a result, the food can be stored for a long time while being fresh. In particular, if a suitable cooling method is employed, the cells of the food can be cooled without being destroyed, so that the water and nutrients of the food can be prevented from flowing out. And the frozen foodstuff is packaged as needed, and is conveyed and stored in a store, a home, etc.

  S4 is a thawing / cooking process, in which thawing and cooking are simultaneously performed using a microwave oven. At this time, the food is put in a special heating container as shown in FIG. When this heating container is described, it consists of a material suitable for use in a microwave oven, for example, a pot-shaped container body 1 formed of polypropylene or the like, and a lid body 2 fitted to the container body 1. The sealed state can be maintained. Further, the lid 2 is provided with a pressure adjusting unit 3 including, for example, a check valve or the like, and has a structure capable of appropriately adjusting the pressure in the container mainly composed of water vapor. Further, as described below, it is preferable that the container is a deep container having a wide space so that the foodstuff is exposed to the water vapor atmosphere. Then, when the frozen food (M) with the above-mentioned grill is put into this heating container and heated in a microwave oven, the food itself is heated by the microwave, heated from inside the food, and the raw food is also cooked in a short time. The At this time, although the water vapor is generated from the food, a constant water vapor atmosphere is formed in the closed container whose pressure is adjusted, and the food is prevented from being dried excessively. In other words, when the inside of the container becomes equal to or higher than a certain pressure, a check valve acts to reduce the pressure in the container and maintain a constant pressure. Moreover, since the baking surface is given beforehand on the foodstuff surface, the gravy which is the origin of umami does not flow out.

  Therefore, according to such a cooking method, it is possible to cook almost the same as a raw food baked over a direct fire without damaging the umami and nutrients, just by heating the frozen food whose surface is pre-baked with a microwave oven. it can. In addition, you can cook as much as you need, so you can use it alone or in a small family.

  The heating container is not limited to the materials and shapes described above, but can be round, oval, oval, etc., in addition to the ingredients, and the pressure adjustment unit is also limited to a check valve. Instead, various conventionally known pressure adjusting mechanisms can be employed. That is, any sealed container having a predetermined size suitable for heating by a microwave oven may be used as long as it has a function of maintaining a constant water vapor atmosphere in the container.

  Moreover, as what can apply the said cooking method, as mentioned above, it can be set as the frozen food which accommodates and provides the foodstuff which gave the surface a baking mark beforehand, and was frozen. The frozen food having such a configuration can be easily obtained as a freshly baked food simply by heating with a microwave oven in an individual home or store.

It is a flowchart which shows the outline of the cooking method of the frozen food which concerns on this invention. It is sectional drawing which shows an example of the heating container used for this cooking method.
