Description

  The present invention relates to a method for producing a dry starch noodle-like food that can be reconstituted in a short time within about 5 minutes and has a tocorotene-like texture and a gummy jelly-like texture.

Conventionally, various dried starch noodle-like foods such as vermicelli and kuzuri have been disclosed. These dried starch noodle-like foods are boiled with hot water, etc., seasoned and eaten after restoration, and have a tokoroten-like texture (noodle-like smooth texture and elastic texture) ), But also has a texture that is easy to cut.
In addition, dry starch noodle-like foods with improved resistance to stew by a unique manufacturing method are also disclosed (Patent Documents 1 and 2).

  However, these dried starch noodle-like foods did not have a gummy-like texture produced in the confectionery field with gelatin as the main ingredient. In view of the above circumstances, the present inventors have a tokoroten-like texture that vermicelli, kuzukuri, and the like have, and also have a gummy jelly-like texture, which is short only by pouring hot water. A starch noodle-like food having a new texture that can be reconstituted in hot water and can be eaten and a method for producing the same have been developed (Japanese Patent Application No. 2007-122098) (hereinafter referred to as the prior method).

The said prior method can be utilized as a method which can manufacture the starch noodle-like foodstuff which has a novel food texture. This manufacturing method uses a method in which all starches are once gelatinized and then spread and formed into a sheet.
However, since the whole starch is once gelatinized in the prior method, if the starch concentration is high, the starch solution after gelatinization has a high viscosity. For this reason, resistance may be generated when mixing and stirring, and the energy load in the apparatus tends to be excessive. In addition, when a gelatinized starch solution having a high viscosity is spread in a large amount into a sheet, an excessive burden due to the high viscosity is applied, which may hinder efficient production processes.

  Furthermore, when it is cooled after being gelatinized by heating, if the starch concentration is high, the starch solution may gel as the temperature of the gelatinized starch solution decreases, and the fluidity may decrease. Therefore, if the process does not proceed to the molding step immediately after heating and gelatinization, the gelatinized starch solution is allowed to stand for a certain period of time and may gel during this time. And if it gelatinizes in this way, since it will become difficult to extend to an appropriate sheet form, it will become a hindrance in progressing a subsequent manufacturing process, and workability | operativity will fall.

Japanese Examined Patent Publication No. 39-27465 JP-A-2-295445

Therefore, we have improved the previous method of forming all the starch as a raw material into a sheet form after complete gelatinization, and the workability does not deteriorate even if the gelatinized starch solution is left as it is. The object was to develop a production method with improved workability in the production of food.

  As a result of various process studies for the above purpose, the present inventors previously prepared a starch solution that was completely gelatinized using a part of the starch to be used, and added the remainder of the starch to this. Thus, the present inventors have found an improved method in which a starch slurry having a low viscosity and high fluidity is prepared, and this is spread into a sheet shape and then heated to be gelatinized.

  Specifically, first, water is added to and mixed with a part of the powder of the raw material starch (which may contain sugar and / or dextrin) to be used, then it is gelatinized by heating, and then cooled to about 58 ° C. Reduce the temperature to the following to prepare a gelatinized starch solution. Subsequently, after adding the remainder of mixed starch powder to this, it mixes and the starch slurry which disperse | distributed the non-gelatinized starch granule in the gelatinized starch solution is prepared.

The starch slurry thus prepared is in a state where non-gelatinized starch is mixed in the gelatinized starch solution, but since the gelatinized starch solution has a certain degree of viscosity, it is constant. The added non-gelatinized starch does not settle easily even after standing for a long time, and maintains a mixed state.
Moreover, since the whole starch slurry is not completely gelatinized, the expression of the viscosity in the starch slurry is also smaller than that of the prior method. Thereby, subsequent handling such as spreading into a sheet can be easily performed.

That is, the present invention
A dry starch noodle-like food that is reconstituted with hot water and eaten, the following steps:
A) Starch and water are mixed, sugar and / or dextrin is contained as necessary, and a starch slurry containing about 2 to 8% by weight of starch with respect to the total weight is heated to prepare a gelatinized starch solution. Process,
B) cooling the gelatinized starch solution to about 58 ° C. or less;
C) Starch separately prepared in the gelatinized starch solution after cooling, and saccharides and / or dextrin are added, and about 8 to 17% by weight starch and about 1 to 8 saccharides and / or dextrins are added to the total weight. A step of preparing a starch slurry containing wt%,
D) A step of spreading the starch slurry into a sheet to prepare a starch sheet,
E) Steaming the starch sheet to gelatinize it,
F) A step of pre-drying the starch sheet after gelatinization as necessary and cutting it,
G) Hot air drying the gelatinized starch sheet cut product,
Including each step of
A method for producing a dried starch noodle-like food, characterized in that the starch used as a raw material contains mung bean starch and potato starch;
It is.

By using the production method of the present invention, workability does not decrease even if the gelatinized starch solution is left in the production of a novel dry starch noodle-like food having a gummy jelly-like texture. It can be produced more efficiently.

  Hereinafter, the present invention will be described in detail, but the present invention is not construed as being limited to the scope of the following disclosure.

─ Types of starch used ─
The present invention uses starch as the main raw material, but first uses mung bean starch as an essential component. Mung bean starch is a kind of bean starch, but generally bean starch has a characteristic of easily forming a hard gel upon cooling after gelatinization. For this reason, it is effective to use legume starch for the production of the dried starch noodle-like food of the present invention. Further, among bean starches, in particular, when mung bean starch is used, a characteristic gummy jelly-like texture can be developed together with a tocorotene-like texture at the time of eating after restoration.

  A certain amount of mung bean starch can be replaced with other bean starch. In this case, various bean starches such as pea starch and red bean starch can be used. In the present invention, starch other than mung bean starch or legume starch is also used. If only mung bean starch is produced as the raw material starch, the starch gel becomes too hard after cooling after spreading into a sheet form after gelatinization, which hinders the subsequent cutting process. In addition, when hot water is reconstituted in the product after drying, the gel strength is high, and on the other hand, there is a possibility that the expression of tocorotene-like texture may be insufficient.

On the other hand, when only starch other than legume starch including mung bean starch is produced, for example, potato starch or corn starch, the starch gel spread into a sheet after gelatinization tends to collapse even after cooling. However, there is a problem in that boiling down occurs, and a tokoroten-like texture and a gummy jelly-like texture after reconstitution with hot water cannot be obtained sufficiently.
For this reason, in this invention, it is necessary to mix | blend fixed quantity of starches other than legume starch which contains a certain quantity or more of mung bean starch, and legume starch. As starches other than legume starch, it is particularly necessary to use potato starch. This is because when potato starch is used, a good texture can be expressed in a gummy jelly-like texture as compared with other starches. In the present invention, potato starch refers to commonly known potato starch, sweet potato starch and the like, and any of these potato starches can be selected and used.

  A certain amount of potato starch can be replaced with other starches other than legume starch and potato starch. In this case, cereal starches such as corn starch, wheat starch, and rice starch, edible wildflower starches such as kuzu starch, and starches such as stem stalk starch such as palm starch can be widely used. In addition, the above-mentioned various starches can be used even if they are modified starches such as etherification and acetylation.

  Moreover, in order to reflect the subtle difference of food texture about a tokoroten-like food texture and a gummy jelly-like food texture, a desired food texture can be adjusted by adjusting the compounding quantity of each starch.

─Amount of various starches─
About the compounding quantity of starch, when preparing the gelatinized starch solution in A process of this invention, it prepares so that starch may become a low concentration about 2 to 8 weight%. The content within this range is such that when starch is added later by giving the starch solution a certain degree of viscosity, the added starch and gelatinized starch solution are maintained in a mixed state. This is to prevent separation and settling.

In the present invention, a partially gelatinized starch solution is prepared, and the remaining starch is added to this to form a starch slurry, which is then steamed, and the added starch is gelatinized.
The starch slurry is prepared by additionally adding starch to a low-concentrated gelatinized starch solution. The final starch concentration contained in the starch slurry is adjusted to be about 8 to 17% by weight based on the total weight of the starch slurry, including those gelatinized and ungelatinized. This range has a low starch concentration as compared with the conventional methods for producing dried starch noodle foods such as vermicelli and scum, and this is one of the features of the present invention.

  The fact that these starch concentrations are suitable is disclosed in Japanese Patent Application No. 2007-122098 by the present applicant. The range of the various starches to be contained in the final starch slurry before cooking is basically about 20 to 80% by weight of mung bean starch, preferably about 40 to 60%, based on the total weight of the starch. It is contained in the range of% by weight. When a part of the mung bean starch is replaced with another bean starch as an arrangement, the amount of the other bean starch is at most equal to or less than the amount of the mung bean starch.

  For potato starch, the blending amount can be set within the remaining range obtained by subtracting the blending amount of the mung bean starch or bean starch from the total blending amount of starch. That is, the compounding quantity of potato starch is about 80 to 20% by weight, preferably about 60 to 40% by weight, based on the total weight of the starch.

In addition, as described above, a part of the potato starch may be a starch other than legume starch / potato starch, for example, cereal starch such as corn starch / wheat starch / rice starch, edible wildflower starch such as scum starch, and coconut starch. In this case, the blended amount of the substituted starch is at most equal to or less than the blended amount of potato starch.
In addition, it is disclosed in Japanese Patent Application No. 2007-122098 by this applicant about the compounding ratio of potato starches other than these mung bean starch and mung bean starch being suitable.

--Sugar and / or dextrin--
In the present invention, saccharides and / or dextrins are used in combination as raw materials. By containing saccharides and / or dextrins, when the dried starch noodle-like food obtained by the production method according to claim 1 is reconstituted with hot water, moisture can be quickly absorbed to improve reconstitution. Moreover, the thickness of the dried starch noodle-like food after restoration can be increased by the use.

  As sugars to be used, monosaccharides such as glucose and fructose, disaccharides such as lactose, sucrose and maltose, and sugar alcohols such as sorbitol, maltitol and erythritol can be used. The sugar to be used can be appropriately selected depending on the kind and sweetness of the sweetness, but if you want to give a strong sweetness, for example, you can select sucrose or fructose, and if you want to suppress the sweetness For example, lactose may be selected. The use of lactose also has the advantage of preventing sticking to a net or the like on which the starch food intermediate product is placed in hot air drying, which is a subsequent process, and facilitating product recovery after drying.

  Further, as dextrin, DE (dextrose equivalent: the reductive power of sugar solution with glucose as 100) is preferably from 8 to 40, particularly preferably DE10-12. is there. In the present invention, various saccharides or dextrins can be used singly or in combination, and both saccharides and dextrins can be used in combination. However, these saccharides and / or dextrins are selected. As a standard to be used, the use of the dried starch noodle-like food of the present invention and the influence on the taste may be considered.

  About content of saccharide | sugar and / or dextrin, in preparation of the starch slurry which is C process of invention of Claim 1, about 1-8 weight% of saccharides and / or dextrin is contained with respect to the total weight of starch slurry. Blend and prepare as follows.

  With respect to this content range, if it is 1% by weight or less, the effect on the restorability of the final product is weakened. Moreover, if it exists in this range, while being able to suppress the sweetness of an addition saccharide | sugar, rapid hot water return can be implement | achieved. As a result, in the step of spreading the starch slurry after gelatinization in the step C of the invention of claim 1 into a sheet shape, it is possible to secure up to about 4 to 6 mm as the thickness of the starch sheet. Even a manufactured product can be reconstituted with hot water in a short time (within 5 minutes) when restored.

  About addition of saccharide | sugar and / or dextrin, you may make it contain in the gelatinized starch solution in A process, and may add it in the step which prepares the starch slurry in C process. Moreover, a part may be contained in the gelatinized starch solution in A process, and the remainder may be added in the step which prepares the starch slurry in C process.

--Other additives--
In the present invention, starch slurry is prepared by mixing starch, saccharide or dextrin, and water, but various additives other than these can be added. For example, additives such as salt, an antioxidant, an amino acid, and a spice can be added as necessary.

As a compounding quantity of salt, about 0.1 to 3.0 weight% is preferable with respect to the total weight of the starch slurry in C process. If it exceeds 3.0% by weight, the salty taste becomes strong and adverse effects on the taste occur.
When an antioxidant is added, it is possible to prevent the generation of a strange odor due to the deterioration of fats and oils contained in a trace amount in the raw material starch. The amount of fats and oils contained in starch varies depending on the type of starch. Specifically, when tocopherol is added as an antioxidant, it is sufficient to add about 200 ppm of the weight of fats and oils contained in the raw material starch. Moreover, the polymeric phosphate etc. which have an antioxidant effect | action can be added. As other additives, it is possible to add amino acids, peptides, or protein-based materials, as well as spices such as pepper, turmeric, and chili and various extracts that can be generally used in foods.

  In addition, about these additives, you may make it contain in the gelatinized starch solution in A process, and may add at the stage which prepares the starch slurry in C process. Moreover, a part may be contained in the gelatinized starch solution in A process, and the remainder may be added in the step which prepares the starch slurry in C process.

--Water--
In preparing the starch slurry, water is added so that the water content of the starch slurry in Step C is about 75 to 91% by weight. In this regard, in the conventional production method such as vermicelli, the starch slurry before gelatinization has a water content of about 47% by weight. Therefore, the water content of the starch slurry in the present invention is relatively large. It is one of the characteristics of the starch noodle-like food produced by

  The reason why the water is added so that the water content of the starch slurry of Step C is about 75 to 91% by weight is that if the amount of water is less than these ranges, a thick starch slurry is formed. The noodle-like food has a hard texture after restoration, and the gummy jelly-like texture that is the object of the present invention cannot be sufficiently reproduced. On the other hand, if the amount of water is greater than these ranges, the gel strength becomes weak, so that the starch gel after cooking in the E step cannot be sufficiently hard, and it becomes difficult to cut into a predetermined shape. This is because workability may be hindered.

  As for the hydration time, in general, all the hydration used in the preparation of the gelatinized starch solution in step A is completed, but a part of water is contained in the gelatinized starch solution in step A. The remainder may be added at the stage of preparing the starch slurry in the C process.

─Preparation of gelatinized starch solution─
As a method for gelatinizing starch in step A, a method of heating a solution containing starch while stirring is common. Specifically, it is gelatinized by heating while mixing the starch slurry using a heating kneader or the like. The heating temperature and heating time are set based on the temperature and time at which starch is gelatinized, but the gelatinization temperature varies depending on the type of starch, so it should be adjusted as appropriate according to the type and amount of each starch used. That's fine. Usually, in order to gelatinize starch, it heats to about 65 to 90 degreeC. Moreover, in order to ensure gelatinization, it heats, stirring preferably until it becomes about 80 to 90 degreeC.

In addition, as described above, sugars and / or dextrin may be contained as necessary during gelatinization in step A.
The starch concentration contained in the starch solution is generally 2 to 8%. If it is in this range, it has an appropriate viscosity with good workability, and after adding separately prepared starch, mixing it and leaving it still does not cause precipitation, and it is a mixture of ungelatinized starch Can be maintained.

--Cooling--
The gelatinized starch solution is cooled to about 58 ° C. or lower. The reason why the temperature is set to about 58 ° C. or less is that when the temperature is higher than about 58 ° C., a part of the starch that is separately added is gelatinized immediately after being added to the gelatinized starch solution, thereby producing a dull starch. Although this temperature varies somewhat depending on the type of starch used, it may be about 58 ° C. or less. Various methods can be used for cooling, but this is usually performed by allowing to cool. Of course, it may be cooled in a refrigerator or the like. In addition, it is preferable that the temperature of the starch solution after cooling shall be about 10 degreeC or more. This is because, although it depends on the starch concentration, if it is approximately 10 ° C. or less, there may be a problem in the fluidity of the starch solution.

─Addition of starch etc. and preparation of starch slurry─
Starch and sugars are added to the gelatinized starch solution. As for the weight of the starch to be added, about 8 to 17% by weight of starch, including gelatinized and non-gelatinized, and about 1 of sugar and / or dextrin with respect to the total weight of the starch slurry after addition of starch. Add ~ 8 wt%. The amount of starch and saccharide to be added is determined according to the blending amount of the final starch and the like. As an additional method, it is sufficient that the added starch or the like is homogeneously mixed in the gelatinized starch solution. In addition to manual operation, a device such as a kneader may be used for mixing. Moreover, in the prior method for completely gelatinizing all starches, if the starch concentration is high after being gelatinized by heating, if the starch concentration is high, the starch solution gels with the temperature of the gelatinized starch solution, and the fluidity May decrease and work may become difficult. On the other hand, according to the present invention, since the starch concentration is low, gelation does not occur, so workability is not difficult.
The starch slurry is in a state where non-gelatinized starch is mixed in the gelatinized starch solution. However, since the non-gelatinized starch does not settle easily, it can be maintained in this state for a certain period of time. Therefore, a time lag may occur before moving to the next process.

─ The process of spreading the sheet ─
In order to spread the starch slurry after adding starch into a sheet, various conventionally known methods can be used. For example, the starch slurry can be spread on a flat plate of a plate-like body and spread into a sheet shape. In the present invention, the viscosity of the starch slurry prepared in Step C is smaller than the complete gelatinized starch solution in the prior method. For this reason, there is no burden when the sheet is spread, and the work can be performed efficiently.

Moreover, if it manufactures continuously, it forms by making starch slurry adhere to a supply roller etc., or it forms into a sheet form, extruding starch slurry from a slit, and this is continuously developed and stretched on a conveyor. A method is also possible.
About the thickness of a sheet | seat, various thickness can be suitably set and prepared as needed. However, in order to express a gummy jelly-like texture when eating a product, the thickness of a gelatinous starch gelatinized sheet (hereinafter referred to as “starch gel”) before hot-air drying described later is about 2.0 mm to 6. It is preferably about 0 mm. For this reason, the thickness at the time of sheet-like expansion | deployment which determines the thickness of a starch gel is adjusted so that it may become in general this range.

─ Steamed ─
Next, the starch slurry sheet spread into a sheet is cooked, and the newly added starch is gelatinized. Various methods can be employed as the method of steaming, but in addition to the method of steaming in batch mode, continuous steaming using a conveyor or the like is also possible. The cooking time can be set as appropriate, but generally it may be performed at 95 ° C. for about 2 minutes. The starch gel gelatinized by this steaming can be obtained.
Moreover, the starch gel after cooking is cooled to such an extent that it has shape retention. This is because shape retention is insufficient in the state immediately after cooking. The cooling in the present invention includes not only forced cooling but also cooling in a room or cooling in a refrigerator. It is preferable to cool until the temperature of the starch gel is about 30 ° C.

In addition, although the starch gel which has shape retention property can be obtained after this cooling, the cut | judging material of a starch gel is manufactured by cutting the said starch gel into a predetermined shape subsequently. Since the cut product is already gelatinized, it can be eaten as it is as a gelatinized starch food.
In this case, it can be provided as a commercial product after various seasonings such as soy sauce and sauce. The starch gel composition may have some moisture volatilized during the production process, but generally contains about 8 to 17% by weight of starch and about 1 to 8% by weight of saccharide and / or dextrin.

─ Cutting ─
The obtained starch gel is cut into a predetermined shape. In addition to mechanical cutting, the cutting can be performed with various cutters or with a die-cutting device. In the cutting, in addition to cutting into an elongated noodle shape, various shapes such as a circular shape, a rectangular shape, a star shape, and a flower shape can be formed by die cutting. Therefore, the shape itself can be other than noodle-like, and is not necessarily similar to so-called conventional starch noodles. In addition, by adjusting the width, length, and thickness of the cutting, it is possible to further emphasize either the expression of the tokoroten-like texture or the gummy jelly-like texture that is the object of the present invention.

  In the cutting, it is also possible to cut the obtained starch gel after preliminary hot air drying to some extent, if necessary. By doing so, there are cases where cutting can be performed efficiently. In this case, hot air drying described later is further performed after cutting to adjust to a predetermined moisture content in the final product. Further, a method of cutting after drying to a predetermined moisture content in the final product is also possible.

─Hot air drying─
For hot air drying, a normal hot air drying method can be used. As the hot air dryer, various types such as a box type, a tunnel type, and a spiral type can be used. As drying conditions, the drying temperature is preferably about 70 ° C to 97 ° C. If the drying time is about 80 ° C., the drying time is about 3 hours. It is necessary to dry with hot air until the final moisture content of the product is about 5 to 9% by weight after drying. After drying with hot air, the product is returned to room temperature by placing it at room temperature.
The composition of the dried starch noodle-like food after hot air drying produced according to the present invention is about 40 to 89% by weight starch, about 5 to 48% by weight sugar or dextrin, and about 5 to 9% water by weight based on the total weight. It is contained by weight.

─Flushing and eating form─
The dried starch noodle-like food according to the present invention can be eaten simply by pouring hot water and reconstitution with hot water. Therefore, cooking with a pan or the like is not required. It can be restored and eaten within about 5 minutes. In addition, as a form of eating, there is no juice similar to instant noodles, throw away hot water after reconstitution, then entangle with sauce etc., pour hot water after adding soup when reconstitution, The method etc. which eat in the form similar to a cup noodle can be employ | adopted by hold | maintaining for a fixed time about 3 to 5 minutes. Moreover, by selecting the type of sugar to be used, it is possible to make a dried starch noodle-like confectionery that can be flavored in a confectionery style and can be reconstituted with hot water, which is unconventional.

  It is also possible to prepare various types of dried starch noodle-like foods that can be eaten as they are by pouring them into a specific mold and solidifying them, and then drying the ones removed from the molds.

-Product form of the present invention-
The dried starch noodle-like food of the present invention can be used in various product forms. Generally, it can be distributed as a product that can be stored for a long time in a state of being stored in a heat-resistant plastic or paper cup.
Moreover, after pouring and hardening | curing to a specific type | mold, the dried starch noodle-like foodstuff of various forms can be prepared by drying what was extracted from the type | mold.

By using the production method of the present invention, it has a tokoroten-like texture that unprecedented vermicelli, kuzukuri, etc., and also has a gummy jelly-like texture that is squeezed, and only pours hot water. Thus, it is possible to efficiently produce a starch noodle-like food having a new texture that can be reconstituted in a short time and eaten.
As a result, a new field of starch noodle-like food can be provided in the field of instant food, and further development of the food manufacturing industry can be achieved.
