Description

Kijeong rice cake using natural fermenting agent and manufacturing method thereof

The present invention relates to a fermented rice cake prepared using a natural fermenting agent and a method for manufacturing the same. The fermented rice cake of the present invention has excellent nutrient balance by using a natural fermenting agent, has excellent texture and high palatability, and has excellent appearance. have commercial value.

Gijeong-tteok is a rice cake that undergoes fermentation and is called Jeungpyeon, Giji-tteok, Giju-tteok, Bunggeodeok, Sul-tteok, Jeungbyeong, etc. depending on the region. Kijeong rice cakes swell during the fermentation process to form pores, so they have a spongy texture and are quite soft and have a bread-like texture, making them one of the most popular rice cakes. Therefore, Kijeong-tteok is a convenient food and is widely preferred as a meal substitute. However, because Kijeong-tteok uses only rice flour as its main ingredient, the balance of nutrients is poor.

On the other hand, the conditions of the rice cake manufacturing method can change considerably depending on the type of rice cake and what toppings are used. can In the case of Kijeong-tteok, it has a special texture that is different from other rice cakes, so it is more affected by the toppings, so it is difficult to select a topping to balance the nutrients.

Korean Patent Publication No. 10-2020-0129512

One object of the present invention is to provide a method for producing a kijeongtteok having excellent nutritional balance, excellent texture and high taste, and having excellent appearance and high marketability.

In order to achieve the above object, the present invention comprises the steps of mixing rice flour, salt, sugar, water, and makgeolli yeast; primary fermentation of the mixture; Secondary fermentation of the primary fermentation product; And it provides a kijeongtteok manufacturing method comprising the step of steaming and putting a topping on the secondary fermented product.

In one aspect, mixing rice flour, salt, sugar, water, and yeast; Primary fermentation of the mixture at 20 to 23 °C for 8 to 10 hours; Putting the primary fermented product into a mold and performing secondary fermentation at 35 to 40° C. for 50 to 70 minutes; and placing a topping on the secondary fermented product and steaming with steam for 30 to 40 minutes.

It may be desirable to use less water than the amount generally used in consideration of the rise of the vegetable layer. The rice flour, salt, sugar, water, and yeast may be added in a weight ratio of 480 to 520 g of rice flour, 2.8 to 3.2 g of salt, 55 to 65 g of sugar, 45 to 55 g of water, and 0.8 to 1.2 g of yeast. More specifically, it may be added in a weight ratio of 500 g of rice flour, 3 g of salt, 60 g of sugar, 50 g of water, and 1 g of yeast. The weight of each component increases proportionally as the weight of the specific component increases, for example, based on 1 part by weight of water, 10 parts by weight of rice flour, 0.06 parts by weight of salt, 1.2 parts by weight of sugar, and 0.02 parts by weight of yeast. can The amount of salt and sugar is important not only for taste, but can also be important for yeast to ferment to an appropriate degree during fermentation.

The yeast is a yeast used for makgeolli, and makgeolli may be used instead of yeast. The makgeolli used here is raw makgeolli, meaning makgeolli in which yeast can grow in a specific environment. In the case of using makgeolli yeast, material supply is easy and fermentation rate is superior to that of using dry yeast, but it may be more preferable to use dry yeast because the taste may change depending on the state of makgeolli. .

At this time, the yeast may be Saccharomyces cerevisiae and/or Aspergillus oryzae , specifically Aspergillus duck material GH1-3, JS2-7 and BP2- It may be any one or more of 1.

It may be preferable that the alcohol content of makgeolli is 5.5 w/w% or less, more specifically 4w/w% to 5.5 w/w%. The amount of yeast in makgeolli may be preferably 3Х10 ⁷ ± 1.5Х10 ⁷ CFU/ml. Although the alcohol content of makgeolli is important to give the unique flavor of Kijeong-tteok, if the alcohol content is too high, alcohol fermentation will proceed further during the fermentation process, which may reduce flavor preference. When using raw makgeolli instead of yeast, the use of water is preferably reduced, for example, 18 to 22 g of water and 28 to 32 g of makgeolli, more specifically 20 g of water and 30 g of makgeolli may be used.

It may be preferable that the rice flour used has a thickness of 10 to 20 mesh, preferably 15 mesh, on average. If the particles are smaller than the above range, the rice cake may become tough, and if the particles are large, it may be difficult to properly form an air layer.

The production method of the present invention includes a two-step fermentation process. The primary fermentation is preferably performed for 8 to 10 hours, more preferably 9 hours at 20 to 23 °C in an environment of 75 to 80% relative humidity, and the secondary fermentation is 35 to 40 in an environment of 80 to 85% relative humidity. It may be desirable to carry out at ℃ for 50 minutes to 70 minutes, more preferably for 60 minutes. Through the two-step fermentation, it is possible to form a sufficient air layer in the rice cake, to enhance the chewy texture rather than the sticky feeling, and to further enhance the flavor by fermentation. If the relative humidity is not appropriate in the fermentation step, the inside may harden through the surface or air layer of the rice cake, or fermentation may not be performed smoothly. In the manufacturing process of the present invention, considering the case of using herbs as a topping, a relatively small amount is generally used compared to the amount of moisture used in the production of rice cakes, so it may be very important to maintain humidity and temperature during the fermentation process.

In the above manufacturing method, the topping may be placed on the secondary fermented product in the order of a mixed grain layer, a vegetable layer, and a nut layer. The rice cake is layered at about 3 cm, for example, 2 cm to 4 cm, and based on 30 g of the rice cake, as a topping thereon, 4 to 6 g of barley, 9 g to 11 g of vegetables, and 4 g to 6 g of nuts. and more specifically, it may be used in a weight ratio of 5 g of barley, 10 g of herbs, and 5 g of nuts.

The multi-grain layer may be one or more selected from the group consisting of barley, soybean, corn, millet and mung bean, preferably barley.

The above-mentioned herbs are gondree, bom dong, wasabi, chrysanthemum, serrata, persimmon, soothing, rapeseed, sedum, amaranth, oak, coltsfoot, water parsley, sagebrush, bracken, sweet potato shoot, eggplant, paprika, mugwort, turmeric, dandelion or It may be a combination thereof, but is not limited thereto. Preferably, the herbs may be gondae, wasabi, chrysanthemum, windbreak, sedum, sedum, butterbur, water parsley, oleander, dandelion herb, or a combination thereof.

The nuts may be chestnuts, walnuts, peanuts, almonds, pine nuts, ginkgo nuts, pistachios, cashews, hazelnuts, pecans, macadamia nuts, or a combination thereof.

Both dried and raw vegetables can be used as the herbs, and those immersed in boiling water for 20 to 30 seconds can also be used. In the case of substituting herbs, it is enough to hold your breath. The moisture in the herbs can make the rice cakes tough, so you may need to squeeze out enough water to remove them before putting them on as toppings. It may be preferable to use barley soaked in water for 5 hours or more, preferably 5 to 8 hours. In order to remove moisture from barley, it may be preferable to use a barley that has been left on a sieve for 1 hour or more.

The ratio of barley and herbs in the topping can be important for the rice cake to have the proper stickiness. In one embodiment, as a topping used in the production method of Gijeong-tteok of the present invention, the grain may be using only barley. There are many grains that can be used as toppings, but barley may be the best choice for use with greens. Sticky grains such as glutinous rice, barley, and brown rice make the rice cake tough, and grains such as beans, mung beans, and red beans spoil the texture and taste of nuts, which is undesirable. Perilla and brown rice do not harmonize with the rice cake and the greens, so the taste decreases, and the oatmeal also mixes with the moisture of the herbs, which can ruin the appearance of the rice cake and make the texture tough.

A portion of the barley layer may be used by mixing it with herbs for appearance, but it is preferable that at least a portion of the layer is spread underneath the herbs. It may be desirable for barley to be laid down as at least 30% of the total barley amount. If barley is mixed with herbs, the color of the rice cake may change as the herbs are deeply soaked into the rice cake, or the appearance and texture may decrease because the barley remains dry on the layer of herbs. Nuts are preferably topping as the last layer for appearance. If the barley layer and the nut layer are placed on the bottom of the herbs, a part of the herb layer may not stick firmly and the quality may deteriorate.

Steaming the rice cake in the manufacturing method may be preferably using a steam oven. If the steam only comes out from the bottom or the top, the herbs may become soft or the rice cakes and toppings may not be sufficiently cooked within 30 to 40 minutes. The water vapor is produced by boiling water and is preferably 100° C. or higher, and a vapor pressure may be applied, but it is preferably 1 to 1.5 bar so that an air layer can be properly formed.

Kijeong rice cake prepared by the manufacturing method of the present invention has a very good balance of nutrients, including cereals, vegetables and nuts, has excellent texture and high palatability, and has an excellent appearance.

Hereinafter, examples and the like will be described in detail to help the understanding of the present invention. However, the embodiments according to the present invention may be modified in various other forms, and the scope of the present invention should not be construed as being limited to the following examples. The embodiments of the present invention are provided to more completely explain the present invention to those of ordinary skill in the art.

Preparation Example 1: Preparation of Kijeong Rice Cake

To prepare 500 g of rice flour by sieving it through a sieve of about 15 mesh, 3 g of salt, 60 g of sugar, 20 g of water, and 30 g of fresh makgeolli were added and mixed well. Then, the rice cake mixture was fermented at about 20° C. for 9 hours, put into a mold and shaped to a thickness of about 3 cm, and then the temperature was raised to about 35° C. and fermented for 1 hour. In the fermented rice cake mixture, 5 g of barley soaked in water based on 30 g of rice cake and dried on a sieve, 10 g of chwinamul (10 g) and nuts (5 g) were laid out in order. Then, it was put in a steamer with steam coming from the slopes, and steamed with steam from boiling water for about 30 minutes to make Kijeong-tteok.

Test Example 1: Confirmation of difference according to fermentation time

Fermentation time is important for Kijeong-tteok, and it was confirmed that the quality of rice cakes changed according to the order and time of fermentation.

Specifically, the rice cake prepared in Preparation Example 1 was used as Example 1, and as a comparative example, it was prepared in the same manner as in Preparation Example 1, except that only the primary fermentation was performed for 10 hours (Comparative Example 1), and only the secondary fermentation was performed for 10 hours. One (Comparative Example 2) was prepared.

As a result, Comparative Example 1, in which only the primary fermentation was performed, showed no stickiness and a tendency to break, whereas Comparative Example 2, in which only the secondary fermentation was performed, was rather soft and the rice cake had a sour smell like alcohol, and thus the taste decreased.

Test Example 2: Comparison of quality of rice cakes according to the four-layer structure

Kijeong rice cakes of the present invention have excellent texture and appearance by stacking toppings in order for each layer. In order to evaluate the effect of the four-layer structure on the texture and appearance of the rice cake, it was prepared as in Preparation Example 1, but in the step of putting a topping on the rice cake, all barley, greens and nuts were mixed to prepare a rice cake in one layer.

As a result, the color of the greens was deeply transferred to the rice cake, and the barley remained dry on the rice cake, reducing the appearance and texture. Moreover, the quality of the nuts was deteriorated because they did not appear to be excellent in nutrients because they were covered with herbs.

Test Example 3: Comparison of quality of rice cakes according to grain types

In order to check whether the quality or preference of rice cake varies depending on the grain type, perilla, oatmeal, brown rice, and mung bean, which are commonly used as ingredients for rice cake among cereals, were used to prepare rice cakes. Specifically, it was prepared as in Preparation Example 1, but instead of barley, perilla, oatmeal, brown rice, and mung bean were topping in the same amount, and a vegetable layer and a nut layer were formed.

As a result, perilla and mung beans were not properly cooked by the manufacturing method of the present invention, so the texture felt rough.

On the other hand, although brown rice was sufficiently cooked, it turned yellow or hardened even when exposed to the air even a little, reducing the appearance and texture. The oatmeal was also fully cooked, but it spread and made the appearance of the greens and rice cakes tough. Therefore, among grains, barley was most suitable to be used with the herb layer.

Among the grains used, rice cakes using mung bean and brown rice, which had the best shape, were compared with rice cakes using barley, and the preference was evaluated for 10 ordinary people. Since the appearance of the rice cake using mung bean was not good when steamed more, the rice cake steamed under the same conditions as the rice cake of the present invention was used. The evaluation score was evaluated as 5 points in appearance and 5 points in flavor including texture in a total score of 10 points, and the scores of 10 people were averaged and displayed. The texture and flavor tests were performed as blind tests in order to block the effects of appearance.

As a result, as shown in Table 1 below, mung bean received almost similar scores to the case of using barley in appearance, but significantly lowered the score in texture, and when brown rice was used, both appearance and texture were poorer than that of barley.
