Description
【０００１】
【発明の属する技術分野】
本発明は、熱水への分散性と溶解性に優れた熱水易分散溶解性粒状寒天に関する。
【０００２】
【従来の技術】
寒天は、テングサ科やオゴノリ科などの紅藻より熱水抽出されたゲル化特性を有する多糖類を脱水処理することによって得られる乾物である。寒天は、中性の多糖であるアガロースとそれ以外のイオン性の成分を持つアガロペクチンから組成されている。寒天は、同類の紅藻よりなるカラギナンと異なり、親水性のイオンが少ないことと分子の網目構造の違いから、カラギナンが沸騰まで必要としない温度、例えば８０℃で溶解できるのに対し、加熱沸騰するような状態、すなわち１００℃近くに達しないと溶解しないという特性を有する。
【０００３】
寒天は、日本で発明され３５０年以上の歴史を持つ乾物で、主にみつ豆や、フルーツなどを入れて彩りよく固めてゼリー状にした寒天寄せなど、一般家庭で食されているデザートの素材として利用されている。一般家庭において、このようなデザートを作る場合、寒天は、水とともに鍋に入れられ、加熱沸騰させて溶かすことによって利用されている。しかしながら、近年の食生活の変化から、より簡便なもの、例えばポットの湯に溶かすことが求められており、加熱沸騰という方法が敬遠されつつある。
【０００４】
【発明が解決しようとする課題】
一方、特許第１５２０３０４号公報、特許第２５０４７７６号公報及び特許第２０３６０９０号公報には、寒天を非晶質化、すなわちアモルファス化することによって、寒天を沸騰させずに低温で溶解させることが記載されており、寒天の溶解簡便化に可能性を見出している。
【０００５】
しかしながら、このように非晶質化された寒天であっても、例えばポットなどの湯に一度に加えると、十分に分散せずにダマになってしまう場合があり、一般家庭などで使用する消費者向け商品としては適切でない。また、溶解に対して湿潤性が悪い場合、溶解するのに時間がかかり、熱水の温度が下がるため、寒天が完全に溶解しないという問題もある。この結果、見かけ上は、ゼリーに群雲のような寒天分子の凝集物ができてしまうという好ましくない現象も生じることがある。さらに、上述の非晶質化された寒天であっても、寒天の溶解性は、温度のばらつきにかなり影響を受けることがある。例えば、７０℃の温度と８０℃の温度の熱水では、寒天のゼリーとしての凝固力は明らかに差があり、いずれかの温度では使用に耐えない品質となってしまう場合がある。このことは、前述のカラギナンがかなりラフな温度範囲でもその溶解性に問題がないのとは異なる。特に消費者向けの製品においては、鍋で沸騰溶解させずに簡便に溶かす方法として、ポットの湯により溶解させる場合が多いが、ポットの湯は、使用状態により温度のばらつきが多いので、熱水に分散させるには、均一に分散できダマにならずに短時間で湿潤させる、すなわち濡れ速度が速いことが望まれている。
【０００６】
【課題を解決するための手段】
以上のような問題を解決すべく、本発明者らは、鋭意研究を重ねた結果、非晶質化された寒天が空隙を持って結合された熱水易分散溶解性粒状寒天であって、空隙率が０．２〜０．９に調整されたことを特徴とする熱水易分散溶解性粒状寒天が、熱水への分散性と、濡れ速度、溶解性に優れていることを見出した。
【０００７】
本発明に係る熱水易分散溶解性粒状寒天において、非晶質化された寒天の空隙率が０．２以下であると、水に均一に分散する速度が遅く、また熱水であればこのために寒天が部分的に溶解し、ダマになり易くなってしまい、また、寒天の空隙率が０．９以上であると、お湯に浮遊してダマになったり、また熱水易分散溶解性粒状寒天として固さが維持できず、少しの振動や衝撃により崩壊してしまうという問題がある。
【０００８】
【発明の実施の形態】
本発明において非晶質化された寒天とは、ランダム構造のまま粉体化されたもので、一種のアモルファス化が起こっているものをいい、例えば上述の特許第１５２０３０４号公報、特許第２５０４７７６号公報及び特許第２０３６０９０号公報に記載された方法で製造することができる。本発明に係る熱水易分散溶解性粒状寒天において、前記非晶質化された寒天は、その寒天が含まれた８０℃に加熱された水溶液が、その８０℃の溶解率において８０％以上溶解するものであることが好ましい。
【０００９】
本発明に係る熱水易分散溶解性粒状寒天において、前記非晶質化された寒天は、単一の粒子径が、１８０μｍ以下が８０％以上で、かつ２５０μｍ以下が９５％以上であり、好ましくは粒子径が１５０μｍ以下が８０％以上で、かつ１８０μｍ以下が９５％以上であるところの単一の寒天粒子が空隙を持って結合していることが好ましい。
【００１０】
非晶質化された寒天を粒状に造粒する手段としては、流動層造粒、噴霧乾燥造粒、攪拌造粒、押出造粒、破砕型造粒、転動造粒等がある。流動層造粒や攪拌造粒によって加工する場合、一度非晶質化した寒天からの加工が可能であるので、事前に粒子径を１８０μｍ以下が８０％以上で、かつ２５０μｍ以下が９５％以上になるように調整しておくことができる。噴霧乾燥造粒によって加工する場合、空隙率は、乾燥造粒時に非晶質化しながら０．２〜０．９に調整される。空隙率は、見かけ容積と粉体の容積を測定し、これらの値を数１に当てはめることにより導くことができる。
【００１１】
【数１】
本発明に係る熱水易分散溶解性粒状寒天は、２０℃の水に分散させたとき、１分後の吸水量が寒天１ｇあたり４ｇ以上であることが好ましい。本発明に係る熱水易分散溶解性粒状寒天において、濡れ速度は、２０℃の水に分散させて一定時間後の吸水量を測定することにより求めることができる。このとき分散状態も濡れ速度に与える重要な要素となる。すなわち、熱水易分散溶解性粒状寒天を水に加える場合、一般的には寒天を少しずつ水に加えることはせず、加える量目が一度に加えられることになり、分散性が悪いと部分的に溶解し、ダマになり易くなってしまい、濡れ速度を低下させてしまうことになる。例えば、熱水易分散溶解性粒状寒天を一度に熱水に加えた場合に、一度水に浮き、その後スプーン程度の攪拌によって少しずつ沈み溶けていくタイプのものが好ましい。このようなタイプであれば、熱水易分散溶解性粒状寒天の一様に亘って水分が濡れて行く状態が得られ、結果として濡れ速度が良好なものが得られる。
【００１３】
本発明に係る熱水易分散溶解性粒状寒天によれば、例えば、８０℃の熱水に加えて１０秒から１分程度かき混ぜることによって容易に分散させ、溶解率において８０％以上溶解させることができるので、その後、これを冷却することによりゼリーを容易に作ることができる。したがって、本発明の熱水易分散溶解性粒状寒天は、消費者の家庭料理においても、簡便な方法としてゼリーを作ることができる。なお、本発明において、溶解率とは、溶解温度のみ異なる寒天濃度の同一条件の溶解において、沸騰させ完全溶解させて作ったゼリーを対象として強度比表したものである。
【００１４】
また、本発明に係る熱水易分散溶解性粒状寒天は、分散剤を含ませても良く、その場合、前記非晶質化された寒天と分散剤の含有比が１：０．０１〜５であることが好ましい。本発明において、分散剤とは、造粒された粒状寒天の熱水への分散性を助長させるものであって、例えば、デキストリン、砂糖、乳糖などがある。本発明に係る熱水易分散溶解性粒状寒天は、上述のように分散性に優れているので、分散剤の含有量を少なくすることが可能であり、様々な食品に応用できる。
【００１５】
本発明に係る熱水易分散溶解性寒天は、例えば小さな袋などに包装された状態で提供される。

BACKGROUND OF THE INVENTION
The present invention relates to a hot water easily dispersible and soluble granular agar having excellent dispersibility and solubility in hot water.
[0002]
[Prior art]
Agar is a dry matter obtained by dehydrating a polysaccharide having gelling properties extracted from red algae such as the family Aegyptiaceae and the genus Pleuroceae with hot water. Agar is composed of agarose, which is a neutral polysaccharide, and agaropectin, which has other ionic components. Agar is different from carrageenan consisting of the same red algae, and it can be dissolved at a temperature that is not required until boiling, such as 80 ° C, because of low hydrophilic ions and the difference in molecular network structure. In such a state, that is, it does not dissolve unless it reaches 100 ° C.
[0003]
Agar is a dried product that was invented in Japan and has a history of more than 350 years. It is mainly used for desserts eaten in ordinary households, such as agar gathered in a jelly-like shape by adding peas and fruits. It's being used. In general households, when making such desserts, agar is put in a pan with water and used by melting it by heating and boiling. However, due to recent changes in eating habits, it has been demanded to dissolve in simpler ones such as hot water in pots, and the method of heating and boiling is being avoided.
[0004]
[Problems to be solved by the invention]
On the other hand, Japanese Patent No. 1520304, Japanese Patent No. 2504776 and Japanese Patent No. 2036090 describe that agar is amorphized, that is, amorphized to dissolve agar at a low temperature without boiling. And has found a possibility to simplify the dissolution of agar.
[0005]
However, even agar amorphized in this way, for example, when added to hot water such as a pot at one time, it may become lumped without being sufficiently dispersed. It is not appropriate as a product for consumers. In addition, when the wettability with respect to dissolution is poor, it takes time to dissolve, and the temperature of hot water decreases, so that there is also a problem that agar does not completely dissolve. As a result, an undesired phenomenon that an agar molecule aggregate like a cloud appears in the jelly may appear as a result. Furthermore, even with the amorphized agar described above, the agar solubility can be significantly affected by temperature variations. For example, between hot water at a temperature of 70 ° C. and hot water at 80 ° C., there is a clear difference in the coagulation power as agar jelly, and there is a case where it becomes a quality that cannot be used at any temperature. This is different from the fact that the aforementioned carrageenan has no problem in its solubility even in a considerably rough temperature range. Especially for consumer products, as a method of dissolving easily without boiling in a pan, it is often dissolved with hot water from a pot. In order to disperse in the water, it is desired that the material can be uniformly dispersed and is moistened in a short time without being lumped, that is, the wetting speed is high.
[0006]
[Means for Solving the Problems]
In order to solve the problems as described above, the present inventors have conducted extensive research, and as a result, are hot water easily dispersible and soluble granular agar in which amorphized agar is bonded with voids, It has been found that hot water easily dispersible and soluble granular agar having a porosity adjusted to 0.2 to 0.9 is excellent in dispersibility in hot water, wetting speed and solubility. .
[0007]
In the hot water easy-dispersible soluble granular agar according to the present invention, when the amorphized agar has a porosity of 0.2 or less, the rate of uniform dispersion in water is slow. As a result, the agar partially dissolves and tends to become lumps, and when the porosity of the agar is 0.9 or more, it floats in hot water and becomes lumps, and the hot water easily disperses and dissolves. There is a problem that the hardness cannot be maintained as granular agar and it collapses due to a slight vibration or impact.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, amorphized agar refers to powder that has been powdered in a random structure and has undergone a kind of amorphization. For example, the above-mentioned Patent No. 1520304, Patent No. 2504776 It can manufacture by the method described in the gazette and patent 2036090 gazette. In the hot water easily dispersible and soluble granular agar according to the present invention, the amorphous agar is prepared by dissolving an aqueous solution heated to 80 ° C. containing the agar at a dissolution rate of 80% or more at 80 ° C. It is preferable that
[0009]
In the hot water easily dispersible and soluble granular agar according to the present invention, the amorphous agar has a single particle size of 80% or more of 180 μm or less and 95% or more of 250 μm or less, preferably It is preferable that single agar particles having a particle diameter of 150 μm or less of 80% or more and 180 μm or less of 95% or more are bonded with voids.
[0010]
Examples of means for granulating amorphous agar in a granular form include fluidized bed granulation, spray drying granulation, stirring granulation, extrusion granulation, crushing granulation, and rolling granulation. When processing by fluidized bed granulation or stirring granulation, it is possible to process from agar once amorphized, so the particle diameter is 180% or less in advance of 80% or more and 250μm or less to 95% or more. It can be adjusted so that In the case of processing by spray drying granulation, the porosity is adjusted to 0.2 to 0.9 while being amorphized during dry granulation. The porosity can be derived by measuring the apparent volume and the volume of the powder, and applying these values to Equation 1.
[0011]
[Expression 1]
When the hot water easily dispersible soluble granular agar according to the present invention is dispersed in water at 20 ° C., the water absorption after 1 minute is preferably 4 g or more per gram of agar. In the hot water easy-dispersible soluble granular agar according to the present invention, the wetting rate can be determined by dispersing in 20 ° C. water and measuring the water absorption after a certain time. At this time, the dispersed state is also an important factor giving the wetting rate. That is, when adding hot water easy-dispersible soluble granular agar to water, in general, agar is not added to water little by little. It will melt | dissolve in particular, and it will become easy to become lumps, and will reduce the wetting speed. For example, when hot water easily dispersible and soluble granular agar is added to hot water at once, a type that floats in water and then sinks and melts little by little by stirring with a spoon is preferable. If it is such a type, the state in which water | moisture content gets wet over the uniform of a hot water easily dispersible dispersible granular agar will be obtained, and a thing with a favorable wetting speed will be obtained as a result.
[0013]
According to the hot water easily dispersible soluble granular agar according to the present invention, for example, it can be easily dispersed by stirring for about 10 seconds to 1 minute in addition to hot water at 80 ° C., and dissolved at 80% or more in the dissolution rate. After that, the jelly can be easily made by cooling it. Therefore, the easily dispersed hot water granular agar of the present invention can make a jelly as a simple method even in consumer home cooking. In the present invention, the dissolution rate is an intensity ratio table for jelly produced by boiling and completely dissolving in the same conditions of agar concentrations that differ only in the melting temperature.
[0014]
In addition, the hot water easily dispersible and soluble granular agar according to the present invention may contain a dispersing agent, in which case the content ratio of the amorphized agar to the dispersing agent is 1: 0.01-5. It is preferable that In the present invention, the dispersant promotes dispersibility of the granulated granular agar in hot water, and examples thereof include dextrin, sugar, and lactose. Since the hot water easily dispersible and soluble granular agar according to the present invention is excellent in dispersibility as described above, it is possible to reduce the content of the dispersant and it can be applied to various foods.
[0015]
The hot water easy dispersion soluble agar according to the present invention is provided in a state of being packaged in a small bag, for example.
[0016]
【Example】
Next, examples of the hot water easy dispersion soluble granular agar according to the present invention will be described.
[0017]
Example 1
First, 10 parts by weight of refined agar (Ina Food Industry, trade name “Ina Agar”) which contains almost no agaropectin and has a melting point of 85 ° C. or higher by a melting point measurement method by 1.5% concentration inversion method. After being dispersed in 100 parts by weight of cold water, a heated solution is produced by boiling and heating, and this is performed with a drum dryer (drum diameter 50 cm, manufactured by Hachiko Koki Co., Ltd.) at a drum surface temperature of 120 to 140 ° C. and a peripheral speed of 3.2 m / min. Amorphized agar was obtained by drum drying with a film thickness of 0.2 mm. The amorphous agar was pulverized and the solubility at 80 ° C. was measured. As a result, it was 95%, and the single particle diameter was 95% when 180 μm or less and 100% when 250 μm or less. This amorphized agar 5 kg is granulated using a 1% agar solution in a fluidized bed granulator (Okawara Seisakusho Co., Ltd.), thereby easily dispersing and dispersing hot water according to Example 1. Granular agar was obtained. When the physical properties of the easily dispersed hot water granular agar according to Example 1 were measured, the porosity was 0.40, and the amount of water absorbed after 1 minute when dispersed in 20 ° C. water was 1 g of agar. It was 9.0g per unit. 4 g of this hot water easily dispersible soluble granular agar was added to 500 ml of 80 ° C. hot water at a time to confirm the solubility. As Comparative Example 1, ordinary agar (Ina Food Industry Co., Ltd. S-7) was prepared, and as Comparative Example 2, the amorphized agar before granulation was similarly confirmed for solubility. Furthermore, the gel strength of the hot water easily dispersible and soluble granular agar according to Example 1 and the agar according to Comparative Examples 1 and 2 were confirmed by a rheometer (Sun Science Co., Ltd.) and texture. These results are shown in Table 1.
[0018]
[Table 1]
As described above, it can be seen that the hot water easily dispersible dispersible granular agar according to Example 1 exhibits good solubility even in hot water at 80 ° C., and exhibits excellent dispersibility without forming lumps.
[0020]
Example 2
Next, agar algae such as Amakusa are washed with water and subjected to hot water extraction at a temperature of 70 to 120 ° C. for 1 to 2 hours in the presence of an acid such as acetic acid, sulfuric acid, hydrochloric acid, etc. The solidifying sol component is extracted. Thereafter, pressure filtration is performed with a filter press in order to separate the extracted components and impurities in a high temperature state. Next, the filtrate as the extraction component is concentrated to 4.0% by weight with a concentrator while maintaining the temperature at about 60 ° C. To the agar extract concentrated to 4.0% by weight, 85% by weight of isopropanol is added to the sum of the agar extract and the insoluble solvent to cause precipitation. The precipitate is press dehydrated to remove isopropanol. Thereafter, it was dried by heat and powdered to obtain amorphized agar. When the solubility of this amorphized agar at 80 ° C. was measured, it was 97%, and the single particle size was 96% for 180 μm or less and 100% for 250 μm or less. 100 kg of this amorphized agar is suspended in 500 g of 60% ethanol, spray-dried and granulated with a spray dryer (Okawara Chemical Co., Ltd.), and hot water easily dispersible soluble granules according to Example 2 I got agar. When the physical properties of the easily dispersed hot water granular agar according to Example 2 were measured, the porosity was 0.43, and the amount of water absorbed after 1 minute when dispersed in 20 ° C. water was 1 g of agar. It was 9.5 g. 4 g of this hot water easily dispersible soluble granular agar was added to 500 ml of 80 ° C. hot water at a time to confirm the solubility. The solubility of the agar according to Comparative Example 1 and the agar amorphized before spray drying granulation as Comparative Example 3 were confirmed in the same manner. Further, the gel strength of the hot water easily dispersible and soluble granular agar according to Example 2 and the agar according to Comparative Examples 1 and 3 were confirmed by a rheometer (Sun Science Co., Ltd.) and texture. These results are shown in Table 2.

As described above, it can be seen that the agar according to Example 2 exhibits good solubility even in hot water at 80 ° C., and exhibits excellent dispersibility without forming lumps.
[0022]
Example 3
Next, when the amorphized agar obtained by the same production method as in Example 1 was measured for solubility at 80 ° C., it was 98%, and the single particle diameter was 93% with 150 μm or less. And it was 98% of 180 micrometers or less. 100 kg of this amorphized agar was added to and mixed with 50 g of 85% ethanol, kneaded, and granulated with an extrusion granulator (die diameter 0.5 mm, manufactured by Fuji Powder Co., Ltd.). Dispersed and soluble granular agar was obtained. When the physical properties of the easily dispersed hot water soluble granular agar according to Example 3 were measured, the porosity was 0.40, and the amount of water absorbed after 1 minute when dispersed in water at 20 ° C. was 1 g of agar. 9.2g per unit. 4 g of this hot water easy-dispersible soluble granular agar was added to 500 ml of hot water at 80 ° C. at a time to confirm the solubility. As Comparative Example 4, ordinary agar (S-8 manufactured by Ina Food Industry Co., Ltd.) and as Comparative Example 5 amorphized agar before granulation were similarly confirmed for solubility. Furthermore, the gel strength of the hot water easily dispersible and soluble granular agar according to Example 3 and the agar according to Comparative Examples 4 and 5 were confirmed by a rheometer (Sun Science Co., Ltd.) and texture. These results are shown in Table 3.

Example 4
Next, 100 g of agar (S-7, manufactured by Ina Food Industry Co., Ltd.), which is a dried product, is added to 9 L of water together with 450 g of dextrin (paindex # 4, manufactured by Matsutani Chemical Industry), heated and dissolved, and then spray-dried (Okawara) Spray granulation was carried out by using Kako Koki Co., Ltd., and easily dispersed hot water granular agar according to Example 4 was obtained. The particle diameter of the dry particles of the easily dispersed hot water dispersion granular agar according to Example 4 is 83 μm or less and 83% and 250 μm or less is 96%, and the single particles are adhered during spray drying. Since it was granulated, the porosity was 0.55. Further, the amount of water absorption after 1 minute when dispersed in 20 ° C. water was 10.0 g per 1 g of agar. The hot water easily dispersible and soluble granular agar (22 g) was added to 80 ml of hot water at 80 ° C. at a time to confirm the solubility. The solubility of 4 g of agar according to Comparative Example 1 was confirmed in the same manner. Furthermore, the gel strength was confirmed with a rheometer (Sun Kagaku Co., Ltd.) and texture for the hot water easily dispersed soluble granular agar according to Example 4 and the agar according to Comparative Example 1. These results are shown in Table 4.

[0028]
Example 5
Next, 4 g of easy-to-disperse hot water dispersible agar according to Example 1 was added to 500 ml of hot water at 70 ° C., 80 ° C., 90 ° C. and 97 ° C. (boiling) at a time to confirm solubility. As a comparative example, the solubility of the agar amorphized before granulation according to Comparative Example 2 was also confirmed. The solubility was confirmed by measuring the gel strength with a rheometer (Sun Science Co., Ltd.). The results are shown in Table 5.
[0029]
[Table 5]
As described above, the hot water easy dispersion dispersible agar according to Example 1 was free from lumps at any temperature, and there was little difference in solubility depending on the dissolution temperature, but before granulation according to Comparative Example 2 The agar amorphized had a large difference in solubility due to the occurrence of lumps at any temperature.
[0031]
【The invention's effect】
As described above, according to the present invention, amorphized agar is granulated by adjusting with a porosity of 0.2 to 0.9, thereby being excellent in dispersibility, wetting speed and solubility. A hot water easily dispersible soluble granular agar can be provided.
