The scope of the patent of the present invention is not limited to the above embodiment, but should be defined by the scope of patent application.

2, the main steps of the method of manufacturing packaged cooked food according to a preferred embodiment of the present invention include the following: (Step 21) A method for preparing a packaged cooked food product comprising the steps of: step; (Step 22) placing the main ingredient and the at least one subsidiary ingredient in a packaging container (see Fig. 3); (Step 23) sealing the main foodstuff and the at least one sub-ingredient in the packaging container at room temperature; And (step 24) simultaneously heating and sterilizing the main ingredient sealed in the packaging container and the at least one subsidiary ingredient to obtain the packaged food. The main steps are described in detail later.

The step of performing the non-heated cooking pretreatment for the main ingredient and the at least one subsidiary ingredient in the step 21 further includes a step 211, a pre-treatment step of soaking the main ingredient to absorb water, and a step 212 And a pretreatment step in which one sub-ingredient is washed. In the pretreatment step of immersing the main foodstuff in the step 211, the main foodstuff such as uncooked rice is rapidly washed through a rice washer, and the water is drained and left for about 0.5 to 1 hour, Such as from 5% to 30% of the weight, but not limited thereto, wherein the uncooked rice may be, for example, rice cakes. The pretreatment step of washing the at least one subsidiary material in step 212 may be performed by preparing the sauce according to the mixing ratio and then finishing the at least one subsidiary material including the digester, Cutting, dipping, boiling in boiling water at 100 ° C or baking the surface at a temperature of 150 ° C or higher, slightly frying the oil at a center thereof, and cutting vegetables such as potatoes, carrots, etc. contained in the at least one subsidiary ingredient Or beans are cut and then cut to the specified standard size so as to obtain the same cooking time as the main ingredient through the step of cutting the at least one subsidiary ingredient to the size of the specified standard so that the main ingredient and the at least one After the sub-ingredients have undergone the same cooking time, one of them is over- Comprising the step of preventing indicating different ripening degree undercooked not limited only to this. It should be noted that the purpose of bake to above 100 DEG C or slightly above 150 DEG C of step 212 is to clean and remove the meat of the meat, but never to cook the meat to its center, Therefore, the processing time of the above step is very short and takes only 30 to 60 seconds. Also, it should be understood that steps 211 and 212 may be performed simultaneously or stepwise.

Step 21 is a step of cooling the pre-processed main ingredients such as uncooked meat and at least one auxiliary ingredients such as meat and vegetables or legumes in a refrigerator at a constant temperature of 4 DEG C to inhibit bacterial growth at a low temperature.

3, the packaging container 50 is, for example, a plastic tray which can withstand a high temperature and a high pressure and has a good air-blocking performance, and the packaging container 50 has a structure in which the pre- (51), (52) having two independent spaces by a partition plate (53) so as to be able to contain at least one subsidiary material, respectively. 2 and 3, in the next step 22, the unprocessed raw material after the pre-treatment, for example, the washing water after the washing, is placed in the storage tank 51 of one of the packaging containers 50 , A food of 0.7 to 1.2 times the above uncooked content, and a trace amount of liquid oil are added. The above-mentioned trace amount of liquid is for imparting gloss and stickiness to cooked rice, and vegetable oil such as common salad oil can be used. In addition, a predetermined amount of the at least one subsidiary ingredient, for example, meat, vegetables or legumes, is contained in another storage container 52 of the packaging container 50, and in step 212, a cooked sauce is added in a fixed amount .

Next, as shown in FIGS. 2 and 3, the process goes to step 23 where the packaging container 50 containing the main food material and the at least one auxiliary food material is hermetically packed at room temperature, To prevent contamination. Here, the sealing step does not require an aseptic environment such as a clean room, and only needs to control the room temperature to between 22 [deg.] C and 25 [deg.] C in a good hygiene environment. Wherein the step of sealing the main foodstuff and the at least one auxiliary foodstuff in the packaging container (50) at room temperature comprises: sealing the cover material (50) with a thermal bonding machine, wherein the plastic The cover material such as a film is sealed with a mold corresponding to the cover material at a heat bonding temperature of 175 DEG C or more for about 3 to 5 seconds through a heat adherer so that the cover material is adhered to an opening (not shown) Seal it. In the preferred embodiment, since the packaging container 50 is a plastic tray provided with two storage tanks 51 and 52, the edge of the tray is sealed with two lines of 0.2 mm seam, The portions of the diaphragm 53 between the storage chambers 51 and 52 are sealed with three 0.2 mm seam lines. In other embodiments, the packaging container 50 is provided with three storage chambers 50, 50, 50, 50, 50, 50, 50, , Four storage tanks, or any packaging tanks including two or more storage tanks.

Finally, as shown in FIG. 2 and FIG. 3, the main foodstuff entering the step 24, that is, sealed in the packaging container 50 and the at least one auxiliary foodstuff are simultaneously subjected to heating cooking and sterilization treatment And the heating and sterilizing process is performed by transferring the main food material and the at least one auxiliary food material sealed in the packaging container 50 to a spinneret sterilizer (not shown) capable of rotating, The heating temperature in the sterilizer is 100 to 130 DEG C, the pressure is 1 to 3 atmospheric pressure (atm), and the rotation speed is the rotation speed (rpm). And sterilized by heating under the above conditions to the center temperature of the main and auxiliary ingredients for 30 to 60 minutes so that the Fo value of the main and sub ingredient materials in the packaging container 50 is interposed between 1-6, It can allow. In the preferred embodiment of the present invention, the rotatable spray sterilizer is selected so that the bottom of the cooked rice is absorbed and absorbed by too much water during the aging of the uncooked rice, The upper layer is to prevent the problem of becoming too hard due to insufficient water absorption. In addition, the processing conditions in the above step can be determined according to the kind of the foodstuff and the condition of the pretreatment. For example, the selection and pretreatment methods of various kinds of foodstuffs can be adjusted with the cooking time of rice cooked at the earliest time. Specifically, if the rice is aged for 30 minutes, the meat in the supplementary ingredients is cut to a size that can be fully ripe within 30 minutes, and a side menu such as potatoes which is not boiled excessively even if the cooking is completed within 30 minutes is selected .
