Problems solved by technology

[0004] In contrast, in the case of heating using microwaves, there occurs a phenomenon in which heating is concentrated at a specific part of the food, and thus uneven heating may occur
Therefore, even if microwaves are used to heat frozen foods, due to uneven heating as described above, frozen parts and warm parts may be mixed in the food. It can also happen that parts become dry or hard
[0005] In the case of products containing two or more kinds of food at the same time and frozen, the phenomenon as described above may occur more seriously, and especially in the case where the heating rates of the two or more kinds of food as described above are different from each other, due to The heating pattern differs depending on the microwave radiation, so there may occur a problem that the product temperature of each of the two or more foods as described above becomes different from each other
For example, in the case of heating a frozen product containing rice and processed meat sprinkled with sauce with the microwave of a microwave oven, when the rice is heated to an appropriate temperature, the processed meat cannot be heated sufficiently while the meat is heated When it reaches the right temperature, it will happen that the rice and sauce will be overcooked and dry out

Embodiment 1

[0040] Prepare 165g of fried rice made of rice at 80% by weight, 60g of beef patty with a thickness of 15mm, and 30g of carrots for decoration that are cut into appropriate sizes and blanched in hot water for more than 1 minute, and are sorted and packed in containers. Then, after adding 2 to 3% by weight of a gelling agent (gelatin) to 45g of Domingueras sauce and pouring it into a cube frame and cooling so that each weight becomes 4 to 5g, after- Freeze at a temperature of 30 to -18°C to make a frozen sauce in block form. The frozen sauce prepared as described above was placed on the beef patty, and frozen at a temperature of -30 to -18°C after vacuum sealing to make a frozen product. Store the frozen product prepared as above at a temperature of -18° C. or lower for one day or more.

experiment example 1

[0044] Confirm product temperature deviation after heating

[0045] After the frozen packaged product made in said embodiment 1 and comparative example 1 was heated in a 700W microwave oven for 6 minutes and 30 seconds in a sealed state, it was opened and a thermometer (manufactured by Testo) was used to measure fried rice, beef patties and The product temperature of the carrots used for decoration, and the average temperature, standard deviation and coefficient of variation values ​​were calculated and shown in Table 1 below. The coefficient of variation is the value of the standard deviation divided by the mean. It is used as an index used when comparing data that have mean and standard deviation values ​​that differ from each other. In this experimental example, a large coefficient of variation means that the product temperature range of each food is wide, and it means that the product temperature has a large variation.

experiment example 2

[0051] Confirm product temperature distribution according to heating time

[0052] The frozen packaged product made in said Example 1 was heated in a 700W microwave oven for 6 minutes and 30 seconds in a sealed state, and the frozen packaged product made in said Comparative Example 1 was heated in a sealed state at 700W. After heating in a microwave oven for 6 minutes and 30 seconds or 8 minutes, the average temperature, standard deviation and coefficient of variation values ​​were calculated by the same method as in Experimental Example 1 and shown in Table 2 below.

[0053] 【Table 2】

[0054]

[0055] As can be seen from the above Table 2, it was confirmed that in order to adjust the average product temperature of the beef patty to the same level as that of Example 1, the frozen packaged product of Comparative Example 1 needs to be irradiated with microwaves for as long as 8 minutes. However, in the case of cooking the frozen packaged product of Comparative Example 1 f...

Abstract

The present application relates to a frozen food product which can be cooked with microwaves, the frozen food product comprising at least two kinds of frozen foods and at least one frozen sauce, the at least two frozen foods having different temperature rising rates in response to microwave irradiation.

Description

technical field [0001] This application relates to frozen products capable of being cooked with microwaves. Background technique [0002] Nowadays, modern people are widely using various instant cooking foods due to their busy lifestyle and culture of pursuing convenience. The types of instant cooking foods including side dishes and processed meat products have gradually become more diversified, and a plurality of instant cooking foods are eaten with various sauces that meet the tastes of ordinary consumers. [0003] In addition, along with the popularization of microwave ovens, heating and cooking food with microwaves has been carried out in daily life. Most of the instant cooked foods as described above are also frozen / refrigerated, and heat-treated by microwaves using microwave ovens to become edible. Microwave ovens heat foods by using the heat generated by making microwaves penetrate the inside of foods and violently vibrating molecules in the electric field of microw...
