DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to tofu, and more particularly to a preferred method for producing tofu prepared by adding prune paste.

[0002]

BACKGROUND ART Tofu is widely eaten as a health food and used in various dishes. Tofu is obtained by adding a coagulant to soy milk and coagulating it, and is prepared using soybean as a raw material. However, since tofu has a pale taste, various flavoring materials such as seasonings and spices are added to it, and products with various characteristics by adding leafy vegetables, seaweeds and fruits are provided. ing.

[0003] As described above, tofu is a processed food in which vegetable protein is easily digested and absorbed, and is an excellent nutritional food containing a large amount of essential amino acids essential for maintaining the health of the human body. However, in view of the content of nutrients such as protein, tofu does not always have a sufficient nutritional value, and there are insufficient points in terms of the nutritional value and in terms of enabling effective intake of nutrients. Was.

[0004] The present invention makes it possible to provide a food which makes use of such inherent characteristics of tofu, has an even higher nutritional value and is suitable for ingesting nutrients, and has characteristics which are not present in conventional tofu. It is an object of the present invention to provide a method for producing tofu, which can be provided as a product having a tofu.

Further, a prune paste, a protein and a coagulant are added to soymilk at about 80 ° C., and the mixture is coagulated at about 90 ° C. for about 30 minutes. Also, after adding prune paste, protein, and a coagulant to soymilk at about 10 to 20 ° C., filling a predetermined pack container with soymilk and sealingly packing the soybean milk, about 90%.
It is characterized by being solidified by heating at about 40 ° C. for about 40 minutes.

[0006]

SUMMARY OF THE INVENTION The method for producing tofu according to the present invention is characterized in that prune paste and protein are added to soymilk and coagulated. Prune paste is prepared by extracting an extract from prunes and preparing it into a paste. This prune paste contains concentrated vitamin and mineral components, and when added to tofu, effectively acts on the decomposition of protein. Its components are as follows. Carotene, vitamins B ₁ , B ₂ , B ₆ ,
Niacin, pantothenic acid, potassium, sodium, phosphorus, calcium, magnesium, iron (energy 250
kcal / 100g)

[0007] Protein is a soy protein food and is added for the purpose of supplementing vegetable protein.
Protein contains isolated soy protein, soy plant fiber, lecithin and yeast extract. By adding this to tofu, it can be provided as tofu having excellent nutritional value.

The amount of prune paste and protein to be added to soy milk is 100% for prune paste.
about 1 to 2 g per gram.
About 0.5 g to 1 g per 00 g is preferable. Prune paste has a dark brown color, and when added to soy milk, tofu is colored. Therefore, the amount of prune paste added is preferably an amount that is accepted as tofu without discomfort and is colored to the extent that appetite is inspired. When the amount of the prune paste added is in the above range, the resulting tofu exhibits an amber color or a pale brown color, and thus is finished in a beautiful color that invites appetite, and is also suitable as a vitamin and mineral content.

[0009] Protein is provided as a powdered product. Therefore, when it is added to soymilk, it may be added as it is. However, the addition of protein has the property of making the tofu slightly hard. Therefore, it is preferable to adjust the sugar content of soy milk assuming the hardness of the tofu in the finished state. Usually, the concentration of soymilk used when preparing tofu is about 8 to 13 as measured by a refractometer. If the sugar content is low, it will be soft tofu, and if the sugar content is high, it will be hard tofu. When protein is added, the finish is slightly increased, so that a sugar content of about 9.5 to 10 is appropriate.

When protein is added, a unique flavor such as yellow flour (kinako) can be felt. It is good to adjust the amount of addition. According to the actual test results, as described above, soy milk 10
It is generally 0.5 g to 1 g per 0 g.

In producing tofu to which prune paste and protein are added, prune paste and protein are added at the soy milk stage, and a coagulant is added as in the conventional method to coagulate. Prune paste is viscous,
Once diluted with water, etc., it may be added to soymilk. The solidification method is the same as the conventional method. The method of producing tofu by the present inventors is characterized in that when coagulating soy milk, the coagulation is gradually coagulated at a considerably higher temperature than the conventional temperature. This is in order to obtain fine-grained tofu by slowly solidifying.

Since the tofu obtained by the above-mentioned production method contains a prune component and a protein component, nutrients such as protein components are enhanced in the vegetable protein component of the tofu itself, and the tofu prepared from conventional mere soybeans can be obtained. It can be provided as a nutritious food.
In addition, by adding prune paste, vitamins and minerals can be provided as a tofu product containing useful ingredients such as foods, and since the protein is decomposed and can be provided as a food that is easy to be ingested, the active ingredient of tofu is further increased. It can be provided as a live food.

[0013] The obtained tofu is excellent in nutrition, and is provided as an excellent food that conventional tofu is not easy to eat as a food to be easily ingested. This tofu can be eaten in the same manner as conventional tofu, and can be eaten deliciously without any discomfort even if it is eaten in a snack-like manner with fruits, jam, and anko.

In consideration of the nutrients of tofu, it is most effective to add both prune paste and protein to soy milk, but the protein is degraded by adding only a predetermined amount of prune paste. It has the effect of making it easier to ingest and can be provided as a useful food with a better nutritional balance than conventional tofu. By adding prune, the tofu is colored, so that there is also an advantage that various useful values can be obtained as an unprecedented colored tofu. Further, even when only protein is added, it can be provided as a health food having sufficient nutrients as compared with conventional tofu.
In addition, when protein is added, it is characterized by adding a savory taste like adding yellow powder (kinako).

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below. (Production Example of Cut Tofu) First, in preparing soy milk, soybeans are immersed in water for about 12 hours to swell, soybeans are ground with water, and boiled at 95 ° C. for about 15 minutes. Then
The ground one was put in a cloth bag and filtered to obtain soymilk. The sugar content of soy milk was adjusted to about 10 by adjusting the water content.

With the obtained soy milk at about 80 ° C., prune paste was added at a ratio of 1 g to 100 g of soy milk. Prune paste was dissolved in a small amount of water and added.
In addition, protein was added at a ratio of 1 g to 100 g of soymilk. Since the protein was provided as a powder, it was added directly to the soymilk.

Next, bittern was added as a coagulant, and the coagulation process was advanced. In addition, prune paste and protein,
If there is not much time difference in the order of adding the coagulant, there is no problem in any order. Unlike the conventional coagulation step, the coagulation step of this embodiment is to maintain soymilk at a high temperature and to coagulate slowly. That is, the soymilk to which the coagulant was added was 9
The mixture was immersed in hot water at about 0 ° C. and solidified while being sterilized and aged. The coagulation step took about 30 minutes at 90 ° C.
In the conventional coagulation process, soy milk is cooled to about room temperature and coagulated in about 10 minutes. However, when coagulated slowly at a high temperature as in the present example, a characteristic is that tofu with fine texture and containing no excessive moisture is obtained. is there.

The coagulated tofu was cooled to about room temperature in water, allowed to stand for a while, cut into a predetermined size, and sealed in a pack. Cut tofu seals and packs tofu with water. The finished tofu became a velvety with a beautiful appearance. Hardness is almost the same as conventional tofu, and the texture is also the same. The taste has a umami taste in addition to the plain taste of the conventional tofu. This taste is due to the addition of protein.

As another embodiment of the cut tofu, a sugar content of 10
100g of prune paste only to soy milk prepared in
And a coagulant was added in the same manner as in the above example, and sterilized, aged and coagulated at 90 ° C. for about 30 minutes. The coagulated tofu was cut and sealed and packed. The obtained tofu had an opaque color similar to that of the above example, and was obtained as having a hardness almost similar to that of the conventional tofu. When prune paste is added, it is characterized by a slightly sweet and sour flavor.

(Example of Production of Filled Tofu) The method of producing soymilk is the same as that of the above-mentioned embodiment. Also in this example, soymilk whose sugar content was adjusted to 10 was used. In this example, after filtering with a cloth, 80
Cool the soy milk that is about ℃ to about 15 ℃,
Prune paste and protein were added. The purpose of cooling the soymilk is to make it difficult for the soymilk to which the coagulant is added to coagulate. Since the filled tofu is coagulated after filling the soymilk into the pack, it is necessary to prevent coagulation before filling the pack.

To the cooled soy milk, prune paste was added at a ratio of 2 g to 100 g of soy milk in the same manner as in the above example.
In addition, protein was added at a ratio of 0.5 g to 100 g of soymilk. Then, add bittern as a coagulant,
The packs were filled and sealed before the soy milk solidified.

Next, the pack filled with soy milk is filled with 90
Boil at 40 ° C for 40 minutes to coagulate and sterilize the soymilk. Thus, a filled tofu containing a prune component and a protein component was obtained. Filled tofu is packed tightly with only tofu without adding water. The obtained filled tofu had an amber color, and hardness was almost the same as that of the conventional tofu, and was obtained as having a rich umami.

[0023]

As described above, the method for producing tofu according to the present invention is characterized in that prune past is added to soy milk to produce the tofu, whereby the protein component of tofu can be effectively ingested. It can be provided as useful food. In addition, by adding protein to soy milk, it can be provided as an excellent food with high nutritional value and easy to take in nutrients, and as a new tofu product with a new texture and umami component that has never existed before It has significant effects such as being able to do.
