Description

  The present invention relates to instant dry noodles using hot air and a method for producing the same.

  More specifically, the present invention is based on durum wheat flour as a main raw material, solid oil and fat is added to the noodle raw material, and dough obtained by a conventional method in the noodle making process is subjected to pressure under reduced pressure to form a small lump or plate After making the noodle band, the noodle band was made, and it was impossible to achieve in the past, and it was practically 100% using durum flour as the main ingredient. The present invention relates to instant dried noodles (pasta) that can produce dried pasta, and a method for producing the same.

  In recent years, in instant noodles, consumers tend to be “authentic” in their daily lives. For example, instant noodles, especially non-fried fried dry noodles, that is, non-fried cup noodles (ramen), have “viscoelasticity like raw noodles” and “fresh texture like raw noodles” It is desirable to do. From the viewpoint of responding to such demands, each company has been cutting down the ground and innovating non-fried cup noodles (ramen).

  Conventionally, pasta uses durum flour as the main ingredient, and the noodle strings can be directly pressed and extruded by the extruder to give a dense structure to the noodle strings. As a result, the pasta has the original density feeling. Koshi has been realized.

In order to realize the above-mentioned pasta in instant noodles, there are the following problems.
(1) When durum flour is used, hot water return is poor.
This is because the sparse protein value is much higher, around 13 percent, compared to normal wheat flour used for instant noodles.

(2) It is necessary to increase the density of the noodle strings using an extruder or the like.
(3) When the above improvements (1) and (2) are performed together, the hot water return tends to be further deteriorated.

(4) If the noodle strings are extruded directly from an extruder, the efficiency is poor for mass production.
(5) Since pasta is usually a straight noodle strip, it looks very strange when wavy on the noodle strip. Tend to loose, and tend to lose commercial value).

  Patent Documents 1, 2, and 3 are all drying methods using a freeze-drying method, and Patent Documents 1 and 2 are related to noodles at the time of freeze-drying by supplying a large amount of water to pasta in the previous step of freeze-drying. This is a method of improving the hot water return by drying the inside of the wire in a porous manner. Patent Document 3 discloses a method for improving hot water return by using amylase and reducing the strength of the noodle strings. In these methods, it is possible to improve the hot water return by performing the above-described treatment and freeze-drying. On the other hand, however, the freeze-drying method has the disadvantages that the processing time is long and the cost is high. Furthermore, in the freeze-drying method, since the color tone of the pasta after drying is in a white state, the color tone of the dry pasta that consumers image is far from being in the dry state, which is very uncomfortable. There is. In addition, Patent Document 4 discloses a method of instant drying pasta using hot air drying, but in this method, the thickness of the noodle strings obtained is limited, and moreover, in the main raw material, It cannot be made with durum powder alone, and authentic instant pasta tends to be difficult to say.

  The objective of this invention is providing the instant noodle which can eliminate the trouble of the above-mentioned prior art, and its manufacturing method.

  A further object of the present invention is to provide instant noodles using durum flour as a main raw material, which could not be realized conventionally, and a method for producing the same.

  Another object of the present invention is to provide an instant dry pasta using durum flour as a main ingredient and a method for producing the same, which can meet the demands of consumers in recent years.

  As a result of earnest research, the present inventor is able to obtain a plurality of cavities inside the noodle strings by manufacturing the noodle strings using a vacuum noodle banding machine while adding powdered fats and oils to a part of the raw materials. I found.

  As a result of further research based on the above-described novel findings, the present inventor further investigated the problems of the prior art in taste and texture based on the presence of the “multiple cavities inside the noodle strings” obtained as described above. It has been found that it can be remarkably improved and that the noodle strings can be greatly improved. That is, the present inventor uses a vacuum noodle banding machine and uses durum flour as a main raw material, while controlling the “plurality of cavities inside the noodle strings”, while giving the noodle strings density, the taste The present inventors have found that the problems of the prior art in the texture can be remarkably improved, and that the noodle strings can be drastically improved.

  The instant dry noodles of the present invention are instant dry noodles produced by extruding dough made from noodle raw materials containing at least durum wheat flour and solid fats and oils; The “fraying time” in the inside is 10 seconds or less.

  According to the present invention, a noodle string is further produced by applying pressure to a dough prepared from a noodle raw material containing solid fats and oils to durum wheat flour to form a small lump or plate shape; Next, a method for producing instant dry noodles is provided, wherein the noodle strings are dried with hot air.

  The reason why the above-described effect is obtained in the present invention having the above-described configuration is estimated as follows according to the knowledge of the present inventor.

  That is, according to the inventor's knowledge, using a vacuum noodle banding machine, using durum flour as the main raw material, and further adding powdered granular fat to the noodle raw material, The internal powdered fats and oils dissolve to create fine holes in the noodle strings and on the surface of the noodle strings. At this time, the density of the noodle strings is controlled without breaking the dense structure unique to the vacuum noodle banding machine. It is estimated that it can be dried.

  As described above, in the present invention, the density of the noodle strings can be controlled without breaking the unique dense structure of the vacuum noodle banding machine, so that hot water quickly penetrates into the noodle strings when recuperating. As a result, even in instant pasta using durum flour as the main ingredient, while recreating the firmness and firmness that is typical of pasta, noodles can be made with the “bad hot water return” that was a problem in the past. It is estimated that it was possible to solve the problem while reproducing the line density.

  With these synergistic effects in the present invention, the characteristics of the vacuum noodle banding machine can be drawn out to the maximum, and furthermore, “good rejuvenation of hot water” and “texture with the original elasticity of pasta” can be obtained. , The possibility of obtaining a noodle string that can dramatically improve the "noodle string loosening" by the synergistic effect of the unique dense structure of the vacuum noodle banding machine and the original mold release effect of the powdered fat and oil It is estimated that Furthermore, because durum wheat is a high protein wheat, durum wheat itself has a non-sticky and easy-to-unwind property.

It is a graph which shows the result of having measured the cutting strength of various dry noodles of test example 1. FIG. 6 is a schematic cross-sectional view showing a “fraying time” measuring device system used in Test Example 2. FIG.

  Hereinafter, the present invention will be described more specifically with reference to the drawings as necessary. In the following description, “parts” and “%” representing the quantity ratio are based on mass unless otherwise specified.

(Immediate noodles)
The instant noodles of the present invention are instant dry noodles using durum wheat flour as a main raw material and made from a raw material of noodles containing at least solid oils and fats, and the instant dry noodles are "fraying time" in hot water Is 10 seconds or less.

  Such instant noodles use durum flour as the main ingredient, and dough made from noodle ingredients containing solid oils and fats is made into a small lump or plate by applying pressure under reduced pressure. It can obtain suitably by making the noodle strings made into α and then drying the noodle strings with hot air.

  The “instant dried noodle” in the present invention is “instant dried pasta” using durum flour as a main ingredient. The “instant dry pasta” may be any of a so-called stew type, a type in which hot water is added and cooked, and the like.

(Suitable physical properties of noodles)
The noodles of the present invention preferably have the following physical properties.

(Loose time)
The dry noodles of the present invention preferably have a “unwinding time” of 20 seconds or less as measured under the conditions in “Examples” described later. This “detangling time” is further preferably 10 seconds or less, particularly preferably 0 seconds or less. Here, the “unwinding time” refers to the time until the noodle mass to be measured “falls completely” from the partition plate, as will be described later. Of course, if the noodle mass is “stuck” on the partition plate for some reason, the time until the noodle mass will fall is treated as an “error” and the measurement is repeated. To do.

(Cut strength)
The dry noodles of the present invention preferably have a “cutting strength” of 110 to 130 g measured under the conditions in “Examples” described later. This “cut strength” is preferably 115 to 125 g.

<Measurement conditions of cutting strength>
Rheometer: Fudo Kogyo Co., Ltd., trade name: NRM-2010-CW
Three noodle strings are put on the plate, the cutting strength is measured using a piano wire having a table speed of 2 cm / min and a diameter of 0.27 mm, and an average value is calculated.

(Noodle ingredients)
In the present invention, the noodle material is not particularly limited. That is, the material conventionally used for manufacturing instant noodles can be used without particular limitation. More specifically, for example, the main raw materials and auxiliary raw materials described in paragraphs 52 to 62 of “Introduction to New Instant Noodles” supervised by the Japan Instant Food Industry Association can be used in the present invention.

(Main raw material)
The main raw material that can be used in the present invention is durum flour as the main raw material. Durum wheat is a kind of hard wheat and is used for producing pasta. Usually, the protein value is very high (around 13%) compared to flour used for instant ramen, etc., and it is an indispensable raw material for producing crispness, firmness and firmness peculiar to pasta. There are two types of durum wheat, usually a fine-grained durum flour and a coarse-grained durum semolina, which are not particularly limited in the present invention. preferable. Moreover, as other raw materials, it is possible to blend wheat flour, barley flour, starch, etc. as needed. Among the main usable materials, for example, ASW (Australia white intermediate wheat, protein around 10%) for wheat flour, HRW (American red hard wheat, around 11% protein) for starch, and potato starch for starch , Tapioca starch, waxy corn starch, corn starch, wheat starch and the like, and etherified starch, esterified starch, cross-linked starch, oxidized starch and the like obtained using these as raw materials.

(Sub-material)
In the present invention, examples of auxiliary materials that can be used include phosphates, salts, thickening polysaccharides, eggs, gluten and the like.

(Oil and fat)
Next, the fats and oils that can be used in the present invention will be described. From the viewpoints of the “good hot water reversion” and “noodle string loosening” effects, the fats and oils are preferably spherical or / and granular.

(Spherical or / and granular)
In the oil and fat used in the present invention, “spherical and granular” means that the particle shape of the oil or emulsifier is relatively uniform in length, width and thickness. From the standpoint of the “noodle string loosening” effect, the fat and oil particle diameter is preferably 0.1 mm or more, and more preferably 0.15 mm or more. In the present invention, the particle size of the oil and fat can be suitably measured by the following method.

<Measurement method of particle diameter>
A particle size was automatically measured by a sonic sieving method using a sonic vibration type fully automatic fluidized particle size distribution measuring instrument Robot Shifter RPS-85 (Seishin Enterprise Co., Ltd.).

(Specific examples of fats and oils or emulsifiers)
The kind of fats and oils that can be used in the present invention is not particularly limited. That is, it can be used by appropriately selecting from various types of oils and fats conventionally used for foods or instant noodles in general (combining a plurality of types as necessary).

  Examples of the types of fats and oils described above include lard, palm oil, soybean oil, coconut oil, sunflower oil, cottonseed oil, corn oil, rice bran oil, rapeseed oil, sesame oil and the like. The melting point of fats and oils can be appropriately controlled by performing hydrogenation according to a conventional method.

(Oil production method)
The manufacturing method of the fats and oils that can be used in the present invention is not particularly limited. Examples of usable methods include a spray cooling method, a spray drying method, a drum drying method, and the like. From the viewpoint of the efficiency of the effect of the present invention, the spray cooling method is more preferable. In the spray cooling system, the oil or fat is dissolved and sprayed into a cooling tower (chiller), whereby spherical or granular oil or fat having a particle diameter of 0.1 mm or more can be obtained relatively easily.

  Since the powdered fats and oils obtained by the spray drying method have a small particle size (usually about 0.03 mm in the particle size obtained), the particle size of 0.1 mm or more is compared with the above spray cooling method. It may be a little difficult.

  Further, in the drum dry system, when a particle diameter (thickness) of 0.1 mm or more is obtained, the obtained shape tends to be a relatively large flake shape. For this reason, in order to form spherical or granular oils and fats, secondary processing may be required using a pulverizer such as a mill, resulting in variations in the shape and size of the particle diameter, poor yield, etc. The manufacturing cost may be high.

  Examples of the various powdered fats and oils include “Spray Fat PM” manufactured by Riken Vitamin Co., Ltd. in the spray cooling method. As for the drum drying method, for example, “Unishort K” manufactured by Fuji Oil Co., Ltd. can be mentioned.

(Noodle manufacturing method)
As the noodle making method before the drying step, durum flour was used as a main raw material, and a spherical or / and granular noodle raw material containing at least fats and oils and water were mixed and prepared. Using dough, apply pressure under reduced pressure in an extruder or extrusion molding machine to make a small lump or plate, after compound noodles, cut the noodles with a cutting blade and continuously alphatize, It is preferable to produce an instant dry pasta by drying by. Moreover, the loosening at the time of eating can be improved further by making a loosening liquid etc. adhere to a noodle string before hot air drying. As a loosening agent to be used, conventionally used emulsified fats and oils, emulsifiers and soybean dietary fiber of “Soya Five S” by Fuji Oil Co., Ltd. may be used.

(Vacuum noodle banding machine)
An apparatus for forming an extruded noodle band using an extruder or the like under deaeration that can be used in the present invention is not particularly limited. More specifically, for example, a deaeration apparatus (hereinafter referred to as “vacuum noodle banding machine”) in a noodle dough production apparatus disclosed in JP-A-61-132132 (Japanese Patent Application No. 59-254855) is suitable. Can be used for

  As specific conditions for use, an extruder (extrusion screw) or an extrusion molding machine is pressurized under a vacuum of 650 to 760 mmHg, and a cylindrical dough (dough) is passed through a die having a diameter of 5 to 50 mm. The noodle strips can be obtained by intermittently cutting the pumped product as a small block having a length of 5 to 300 mm, or by taking out the noodle strips.

(Gatinization process)
The pregelatinization treatment method in the present invention can be optionally carried out by boiled treatment using boiling hot water, steaming treatment using steam, etc., but more preferably, a steamer using steam is used. This is because, in the boil processing, the added powdered granular oil is eluted from the inside of the noodle strings to the outside, so that it tends to be relatively difficult to obtain a space inside the noodle strings. In addition, in order to improve the texture of the noodle strings obtained, it is preferable to use steam having a higher humidity than dry steam with respect to the quality of steam used in steaming. In the process of steaming (which is a conventional method in the past), it is possible to further improve the return of the noodle strings to hot water during eating by adding more moisture to the noodle strings before cooking. It is possible to reduce the appearance and sensation. Here, “water to be used” is better if an aqueous solution in which fresh water, tap water, emulsifier, edible oil or the like is dissolved is used. As an emulsifier, for example, a glycerin fatty acid ester such as a monoglycerin fatty acid ester, a diglycerin fatty acid ester, or a polyglycerin fatty acid ester may be used, and it is possible to improve the looseness of the noodle strings compared to when simply using fresh water. It is. As a method for giving the aforementioned aqueous solution to the noodle strings, a method such as spraying or dipping may be used. The amount to be sprayed is preferably about 20 to 40 ml per 100 g of noodle strings, and the amount of water may be controlled according to the hot water return condition. (Reference literature Sho 56-38100)

  The instant noodle strings obtained by the above method can be molded and filled into a drying basket one by one, and the instant dried pasta of the present invention can be obtained through a hot air drying process. Moreover, the loosening at the time of eating can be improved further by making a loosening liquid etc. adhere to a noodle string before hot air drying. As a loosening agent to be used, conventionally used emulsified fats and oils, emulsifiers and soybean dietary fiber of “Soya Five S” by Fuji Oil Co., Ltd. may be used.

(Hot air drying process)
In the hot air drying method of the present invention, the noodle strings are preferably adjusted to a temperature of 60 to 110 ° C. (more preferably 80 to 90 ° C.), preferably a wind speed of 1 to 10 m / S (more preferably 3 to 5 m / S). The final moisture of the noodle mass may be dried to 6 to 14% (preferably 8 to 10%) with hot air.

  If the drying temperature is less than 80 ° C., the drying efficiency tends to be poor and the drying time tends to be long. On the other hand, when the drying temperature exceeds 100 ° C., the boiling point of the moisture in the noodle strings is exceeded, so that slow drying becomes difficult, foaming of the noodle strings starts, and it becomes difficult to obtain a dense noodle string. Tend.

  When the wind speed at the time of drying is less than 1 m / S, it becomes difficult to ventilate the noodle mass well, and there is a tendency that uneven drying occurs. On the other hand, when the wind speed exceeds 10 m / S, the noodle mass is pressed against the upper or lower part of the mold, and as a result, the noodle mass does not become rough, making uniform drying difficult, resulting in drying unevenness, There is also a tendency for loosening of the noodle strings during eating.

  Hereinafter, the present invention will be described more specifically with reference to examples.

Test example 1
The following test confirmed the synergistic effect of the vacuum noodle banding machine and powdered fats and oils.

<Manufacture of noodle strings>
Formula: Durum semolina powder (protein 14.5%) 10kg, water 3400ml

  Conditions before drying: Noodle strings with a cutting edge width of 1.55 mm and a noodle thickness of 1.6 mm were opened with a conduit, cut with a substantially straight noodle string, steamed at 0.5 kg / cm 2 for 3 minutes, and then noodle weight 100 g The steamed noodles that were cut into 20 ml were sprayed with 20 ml of a unraveling solution (1.0% aqueous solution of “Soya Five S”, Fuji Oil Co., Ltd.), filled into a drying mold of φ120 mm and dried at 85 ° C.

  The conditions when using a vacuum noodle banding machine were as follows. Degassing was performed at a vacuum degree of 730 mmHg, pressure was applied, a cylindrical dough was extruded through a die with a diameter of 20 mm, and cut into a chip with a length of 50 mm. After the noodles are made of composite noodles, a noodle string with a cutting edge width of 1.55 mm and a noodle thickness of 1.6 mm is cut out with a straight noodle string by opening the lid of the conduit, and 0.5 kg / cm 2 After steaming for 3 minutes, 20ml of fugitive solution (Fuji Oil Co., Ltd. “Soya Five S” 1.0% aqueous solution) was sprayed onto steamed noodles cut into 100g noodles, and air-formed and filled into a φ120mm mold at 85 ° C. Dried.

  The conditions for using powdered fats and oils were palm extremely hardened oils having a melting point of 62 ° C. and an average particle diameter of 0.1 mm.

  Conditions for using a vacuum noodle banding machine and adding powdered fats and oils: The following three conditions were used.

(Three kinds of conditions)
(1) Vacuum noodle bander not used and powdered fats and oils added (final moisture around 10%)
(2) Use of vacuum noodle banding machine and no addition of powdered fats and oils (final moisture around 10%)
(3) Use of vacuum noodle banding machine and addition of powdered fats and oils (final moisture around 10%)

<Measurement of moisture>
The moisture was measured as follows.

Electric dryer: Yamato Science Co., Ltd. Trade name: DN-41
2 g of the obtained noodle strings are dried at 105 ° C. for 2 hours with an electric dryer, and the water content is measured by the weight difference before and after drying.

(Measurement of cutting strength of noodle strings)
Put 80g of noodle strings sample whose cutting strength should be measured into a 700ml draft glass cup (made by Atsugi Plastic Co., Ltd.), then add 100 ℃ hot water to the draft line in the polystyrene cup and quickly cover with aluminum foil. And left as it is for 5 minutes. The lid was removed, the noodle strings were split using chopsticks, and the measurement of “time after recuperation” was started. At this time, as a time measuring means, a stopwatch manufactured by Seiko Syard Co., Ltd., trade name Seiko Top Watch S052 was used.

  After counting accurately for 5 minutes with the stopwatch, hot water was quickly separated from the noodle strings, and the cutting strength of the noodle strings was measured with a rheometer.

<Measurement conditions of cutting strength>
Rheometer: Fudo Kogyo Co., Ltd., trade name: NRM-2010-CW
Put three noodle strings on the plate, measure the cutting strength using a piano wire, and calculate the average value.

  The measurement result obtained by the above is shown in the graph of FIG.

  It can be understood from FIG. 1 that in the sample according to the condition (2), a strong noodle string can be obtained by a vacuum noodle banding machine. Moreover, in condition (3), it will be understood that hot water reversion is improved by adding powdered fats and oils together. Further, when the inclination of the graph is seen, it can be seen that the inclinations of the graphs in (2) and (3) are strong. That is, it can be understood that the surface of the noodle strings is firm and firm. This firmness and firmness is a texture unique to pasta with a sense of density.

  About 120 g of the cutting strength measured by the above was suitable for instant noodles. When the cutting strength exceeded 130 g, it felt “hard”. Further, the noodle strings of the condition (1) did not use a vacuum noodle strip, and thus had a texture without density and elasticity.

  Moreover, the sensory test of the noodles obtained by the above and the result of proper noodle making are shown in Table (1).

Table (1): Sensory test of conditions (1) to (3) and proper noodle making

  In the above table, 5 is the best for stiffness, and a larger number than 5 indicates that there is too much stiffness.

  From Table (1), by using a vacuum noodle banding machine as condition 3, the noodle viscoelasticity, transparency, weight, etc., which are the original characteristics of pasta, are not spoiled, and hot water is returned by adding powdered fat and oil. It will be understood that I was able to get a good balance of instant pasta. Furthermore, the steamed noodles are very easy to loosen without waving, and can be easily loosened at the time of eating, so that the noodles of pasta (especially spaghetti type) can be reproduced in instant pasta. Here, in (1), the noodles have little stiffness and are powdery, so the return condition was set to 3.

Test example 2
<Measurement of loosening effect>
The loosening effect of the noodle strings obtained under the conditions (1) to (3) was measured by the following method.

  The obtained dried noodles were referred to as “Food and Science”, VOL. 35, p. 105 (October 1993), a measurement was made by making an apparatus with reference to the “determination method”. A schematic diagram of the measuring apparatus is shown in FIG. In FIG. 2, reference symbol 1 is a support column (unscrewing rod φ6 mm, length 22 mm), symbol 2 is a partition plate (φ24 mm), symbol 3 is a bottom plate (145 × 145 mm), and symbol 4 is a measurement container (height 120 mm). Show.

(Measurement of loosening of noodle strings)
1500 ml of hot water at 100 ° C. was poured into the box shown in FIG. 2 and left for 90 seconds. After 90 seconds, the rotation speed of the Sinto machine was moved at 30 rpm, and the time until the noodle mass completely dropped from the partition plate was measured.

  The measurement results obtained as described above are shown in Table (2).

Table (2): Results of loosening measurement (seconds)

  In the above table, regarding condition (1), 480 was described as the maximum value because it was not unraveled even when measured for 480 seconds or more.

  Regarding condition (3), the noodle mass completely dropped before 90 seconds after pouring hot water, so it was set to 0 seconds.

  From the table (2), it can be understood that the condition (3) clearly shows that the noodle strings are loose. It can be understood that the synergistic effect of the vacuum noodle banding machine and the powdered granular fat exhibits a very good loosening effect even in a substantially straight noodle string.

Test example 3
