Description

  The present invention relates to a method in which a water-soluble polymer is easily dissolved in a solution without causing ramping, and a readily soluble granule composition prepared by using such a method.

  In order to add a water-soluble polymer such as xanthan gum, carrageenan, and guar gum to water or liquid food to gel or thicken the liquid, it is necessary to first completely hydrate the water-soluble polymer. However, it is known that when these water-soluble polymers are added in the form of powder to water or liquid food, so-called ramping occurs and the powder becomes very difficult to dissolve in the liquid. Lamping is formed when powder is added to a liquid and only the surface of the aggregate of the powder is hydrated and dissolved, and moisture does not migrate to the interior of the aggregate. , Is called dama etc. In particular, a water-soluble polymer tends to cause ramping because it has a property of holding water. Once such ramping occurs, it does not dissolve easily, and it is difficult to completely dissolve the generated lumps, and it is necessary to take a rigorous stirring process such as increasing the stirring strength or increasing the stirring time.

  As conventional techniques for preventing water-soluble polymer lumps, sodium bicarbonate and organic acids are used as anti-powder agents (Patent Document 1), and salts such as sodium chloride, potassium chloride, sodium lactate and potassium lactate are added. Improving dispersibility is disclosed (Patent Document 2). However, this method is not easy to use such as using a foaming action of foaming while generating carbon dioxide gas, and its anti-damaging effect is not sufficient. In particular, when preparing foods for people with difficulty in chewing / swallowing using water-soluble polymers such as xanthan gum and carrageenan, patients and their caregivers can use foods for those with difficulty in chewing / swallowing on the spot (spatels) Many scenes such as preparation by stirring are seen. Under such weak agitation conditions, water-soluble polymers are prone to ramping, and once it is difficult to remove lumps, they can cause aspiration if they remain, like hand agitation. It has been eagerly desired that the water-soluble polymer is well dispersed without causing ramping even under weak stirring conditions.

  On the other hand, Patent Documents 3 and 4 disclose that an organic acid can be added as a liquid component when granulating a glutamine soda crystal, and a sugar granule formed by binding a sour agent to saccharide particles. However, Patent Documents 3 and 4 are intended to prevent agglomerates of the granulated product itself and moisture absorption, and do not disclose any problems specific to the water-soluble polymer such as ramping of the water-soluble polymer. Similarly, Patent Documents 5 and 6 disclose powder mixes containing carrageenan, but only a description that an acidulant can be optionally added to an aqueous medium used when spray-drying carrageenan.

The method for preventing the ramping of the water-soluble polymer of the present invention includes thickening and / or gelation with an aqueous solution containing at least one of malic acid, tartaric acid, lactic acid, fumaric acid, succinic acid or acetic acid, or a salt thereof as a binder. It is characterized by granulating a water-soluble polymer having such properties.
By granulating a water-soluble polymer using such an aqueous solution as a binder, even a water-soluble polymer that is prone to ramping when added to a liquid can be easily dissolved without causing ramping. . The ramping phenomenon of the water-soluble polymer occurs even in unheated low to normal temperature water, but can also occur in heated water. In this regard, the present invention is a method that can remarkably prevent the conventional ramping of water-soluble polymers regardless of heated / unheated water at 0 to 100 ° C., and includes saccharides and other additives. Even when added to the liquid, the ramping of the water-soluble polymer can be prevented.

  Especially, it is preferable to use 1 type, or 2 or more types selected from galactomannans such as xanthan gum, carrageenan, guar gum, locust bean gum, tara gum and the like. Or it is preferable to use carrageenan.

  In the present invention, a specific amount of an aqueous solution containing one or more of malic acid, tartaric acid, lactic acid, fumaric acid, succinic acid or acetic acid, or a salt thereof is used as a binder for granulating the water-soluble polymer. In particular, the use of at least one of malic acid, tartaric acid or lactic acid, or a salt thereof can remarkably prevent the ramping of the water-soluble polymer. The type of salt is not particularly limited as malate, tartrate, lactate, fumarate, succinate or acetate, and various salts can be used. For example, alkali metal salts (for example, sodium salt, potassium salt) Etc.), alkaline earth metal salts (for example, calcium salts, magnesium salts, etc.), manganese, nickel, chromium, iron, copper, zinc and the like. Among them, sodium salt, potassium salt, or calcium salt, particularly sodium salt can be preferably used in the present invention.

  In the ramping prevention method of the present invention, 1 to 20 parts by weight, preferably 1 to 20 parts by weight, based on 100 parts by weight of the water-soluble polymer, of one or more of the above-described malic acid, tartaric acid, lactic acid, fumaric acid, succinic acid or acetic acid, or a salt thereof. Is preferably granulated so as to contain 5 to 15 parts by weight. Here, when the addition amount of one or more of malic acid, tartaric acid, lactic acid, fumaric acid, succinic acid or acetic acid, or a salt thereof is less than 1 part by weight with respect to the water-soluble polymer, the effect cannot be sufficiently exhibited. There is.

  A water-soluble polymer having malic acid, tartaric acid, lactic acid, fumaric acid, succinic acid or acetic acid, or one or more additions thereof, and a thickening and / or gelling property in the binder in the granulation step The amount of the binder to be added is not particularly limited as long as the mixing ratio of one or more of malic acid, tartaric acid, lactic acid, fumaric acid, succinic acid or acetic acid, or a salt thereof and a water-soluble polymer is within the above range. It can be appropriately adjusted depending on the solubility of the salt, the conditions of granulation, and the like. Specific examples of one or more addition amounts consisting of malic acid, tartaric acid, lactic acid, fumaric acid, succinic acid or acetic acid, or salts thereof in the binder include malic acid, tartaric acid, lactic acid, fumaric acid, succinic acid in an aqueous solution. Or it is preferable to add so that the addition amount of 1 or more types which consists of acetic acid or these salts may be 1-20 weight%, Furthermore, 5-15 weight%.

  As an addition amount of a binder, 10 to 100 weight% with respect to the granulated powder, Furthermore, 20 to 60 weight% can be mentioned as a suitable example. The amount of the binder added can be arbitrarily changed according to the degree of granule growth during granulation.

  As a granulation method, it can carry out using methods, such as stirring granulation, extrusion granulation, rolling granulation, fluidized bed granulation, etc. which are generally performed in the field of food and medicine. Especially in this invention, the ramping of water-soluble polymer can be prevented notably by granulating by fluidized-bed granulation. The following method can be illustrated as a granulation method by fluidized bed granulation. For example, powder is put into a granulator and hot air is sent from below to make the powder flow. A method of producing granules by spraying a binder liquid onto the fluidized bed, allowing the binder liquid to uniformly adhere to the powder surface, forming aggregated particles, and drying the aggregated particles can be mentioned. In addition, it is preferable to granulate so that the particle diameter of a granule may be 75-1200 micrometers.

  In the binder used in the present invention, in addition to one or more of malic acid, tartaric acid, lactic acid, fumaric acid, succinic acid or acetic acid, or salts thereof, dextrin, xanthan gum, carrageenan, Optional components such as guar gum, pullulan, potassium chloride, citric acid or citrate can also be blended.

  Furthermore, the present invention relates to a readily soluble granule composition produced by the above-described method, in which the ramping of the water-soluble polymer powder is prevented.

  The readily soluble granule composition of the present invention is one or more of the aforementioned malic acid, tartaric acid, lactic acid, fumaric acid, succinic acid or acetic acid, or salts thereof, and water-soluble having a property of thickening and / or gelling. In addition to the polymer, the food raw material can of course be added with other food additives as long as the effects are not hindered. For example, amino acids such as sodium L-glutamate and sodium L-aspartate or salts thereof, nucleic acids such as disodium 5'-inosinate or salts thereof, organic acids such as monopotassium citrate or salts thereof, and potassium chloride Seasonings represented by inorganic salts; mustard extract, horseradish extract, and kojic acid, etc .; shelf life improvers; silicoprotein extract, polylysine, and preservatives such as sorbic acid, benzoic acid; α / β amylase Enzymes such as citric acid, fumaric acid, succinic acid, etc .; emulsifiers such as sucrose fatty acid ester, glycerin fatty acid ester, organic acid monoglyceride, lecithin; fragrance; β-carotene Colorants such as Anato pigments: swelling agents; proteins such as whey protein and soybean protein; sucrose, fructose, reduced starch saccharified, Suritoru, sugars xylitol; sucralose, thaumatin, acesulfame potassium, a sweetener such as aspartame; vitamin A, vitamin E, vitamins such as vitamin K; iron, minerals such as calcium and the like.

  The content of the water-soluble polymer having the property of thickening and / or gelling in the readily soluble granule composition of the present invention can be appropriately adjusted depending on the viscosity and gel strength required for the final composition. In the easily soluble granule composition, 1 to 80% by weight, preferably 10 to 60% by weight, more preferably 20 to 50% by weight can be contained.

  Conventionally, in order to increase the dispersibility of water-soluble polymers having the property of thickening and / or gelling in easily soluble granule compositions, a device such as increasing the proportion of dextrin, saccharide, etc. to be blended as a dispersant. Has been made. However, if the content of the water-soluble polymer in the easily soluble granule composition is small, it is necessary to add a large amount of the composition in order to exert the original effects of the water-soluble polymer such as thickening and / or gelation. Therefore, improvement was sought. When the method according to the present invention is adopted, the content of the water-soluble polymer can be appropriately adjusted according to the purpose as compared with the conventional granule composition, and thus the function of exhibiting properties such as thickening and / or gelation can be achieved. Can provide a high granular composition.

  The prepared easily soluble granule composition has a thickening and gelling effect because it prevents water-soluble polymer ramping even when dissolved in a liquid such as water or liquid food under weak stirring conditions such as manual stirring. A composition or gelled product which is applied to a wide range of required compositions and is easily thickened can be prepared. For example, an easily soluble granule composition granulated by using a water-soluble polymer powder having a thickening property such as xanthan gum or carrageenan is easily dissolved even at room temperature when added to a liquid such as water or liquid food. It exhibits a high viscosity, or exhibits its original gel strength when cooled. Moreover, it is excellent in water retention, has a good bolus forming ability (easy to collect foods in the mouth), and can be made into a food having physical properties with little adhesion. That is, these properties sufficiently satisfy the texture and functional properties required for foods for persons with difficulty in chewing / swallowing, and the easily soluble granule composition of the present invention is an aid for those having difficulty in chewing / swallowing. It becomes an easily soluble granule composition suitable as a composition. Furthermore, since the easily soluble granule composition of the present invention can prevent the ramping of the water-soluble polymer even under weak stirring conditions such as hand (spatel) stirring, the patient and its caregiver can easily chew and It has the great advantage of being able to prepare a food for persons with difficulty in swallowing, and is also suitable as an auxiliary composition for persons with difficulty in mastication and swallowing in this respect.

Examples of foods to which the easily soluble granule composition of the present invention is added include, for example, water, milk, milk drinks, lactic acid bacteria drinks, soft drinks with fruit juice, carbonated drinks, fruit drinks, vegetable drinks, tea drinks, sports drinks,
Functional beverages, vitamin supplemented beverages, nutritional balanced beverages, powdered beverages, fruit wines such as red wine, consommé soups, potage soups, cream soups, Chinese soups and other soups, miso soup, fresh soup, stew, curry and gratin soup Liquid final foods such as sucrose can be mentioned, and these can be added directly to increase the viscosity.

Furthermore, the easily soluble granule composition of this invention can also be added at the time of manufacture of various processed foods.
For example, ice cream, ice milk, lacto ice, sorbet, frozen desserts such as ice confectionery; custard pudding, puddings such as milk pudding and pudding with fruit juice, desserts such as jelly, bavaroa and yogurt; gums such as chewing gum and bubble gum (Plate gum, sugar-coated grain gum); chocolates such as chocolate with flavors such as strawberry chocolate, blueberry chocolate and melon chocolate in addition to coated chocolate such as marble chocolate; soft candy (caramel, nougat, gummy candy, marshmallow Etc.), caramels such as toffee; sweets such as soft biscuits and soft cookies; dressings such as separate dressing and non-oil dressing, ketchup, sauce and sauce Jams such as strawberry jam, blueberry jam, marmalade, apple jam, apricot jam and prazabe; processed fruits such as syrup pickled cherries, apricots, apples and strawberries; processed meat products such as ham, sausage and grilled pork; Fish ham, fish sausage, fish meat surimi, salmon, bamboo rings, hampen, fried satsuma, date rolls, whale bacon, and other marine products Noodles; and other various vegetables.

In addition to these general foods, protein / phosphorus / potassium-adjusted foods, salt-adjusted foods, oil-and-fat-adjusted foods, intestinal foods, calcium / iron / vitamin-enriched foods, hypoallergenic foods, concentrated liquid foods, and mixer food , And special foods such as kizami foods and therapeutic foods.

  The easily soluble granule composition of the present invention can be suitably used for liquid foods that are said to have relatively slow viscosity development due to the addition of a thickener, and at least of the following (1) to (3): Even when it is used in a liquid composition that satisfies one or more conditions, it is excellent in that the viscosity of the water-soluble polymer is rapidly expressed.

(1) The fat content is 0.01 to 15% by weight, particularly 0.1 to 10% by weight, based on the total amount of the liquid composition.
Examples of these liquid foods include milk beverages such as milk, lactic acid bacteria beverages, coffee with milk, teas with milk, milk cocoa, milk shakes, beverages with sour milk, fruit milk, concentrated liquid foods, and the like.

(2) The pH is in the range of 2-9, especially 3-8.
Examples of these liquid foods include fruit juice drinks such as orange juice, soft drinks, acidic milk drinks, and drink yogurt.

(3) The mineral content is 0.01 to 3% by weight, particularly 0.05 to 2% by weight, based on the total amount of the liquid composition.
The mineral content includes sodium, calcium, potassium, magnesium, iron, copper, chromium, molybdenum, manganese, zinc, phosphorus, selenium, lithium, vanadium, cobalt, nickel, boron, germanium, bromine, iodine and the like. Examples of liquid foods containing these fixed amounts of minerals include saline, ionic beverages, vitamin supplemented beverages, nutritionally balanced beverages, soy sauce, sauces, dressings and the like.

Furthermore, it can be suitably used for liquid foods that satisfy the above conditions (1) to (3) in a composite manner. As an example of such liquid food, soup, drink yogurt, concentrated liquid food (1 kcal
/ Nutrient foods in which the qualitative composition of each nutrient is sufficiently taken into consideration so that no significant excess or deficiency of nutrients is caused even by long-term single intake. Specific examples of the concentrated liquid food include a fat content of 2 to 6% by weight, a mineral content of 0.1 to 2% by weight, and a pH of 6 to 7.

  Conventionally, water-soluble polymers such as xanthan gum and carrageenan change the ultimate viscosity and solubility depending on the fat content, mineral content, and pH of the dissolved liquid, resulting in concentrated liquid foods, milk, orange juice, miso soup, and mineral balance beverages. When added to liquid foods such as the above, there are problems such as slow onset of viscosity. If the viscosity is slow, the agitation and dissolution time will increase in preparation of food for patients with difficulty in mastication and swallowing, which is actually intended for patients and caregivers. Because it is slow, it becomes difficult to adjust the viscosity of the target food, and even if it is stirred, the viscosity is not enough. The problem was that the viscosity became too high. However, the present invention can also solve this point.

Hereinafter, the content of the present invention will be specifically described with reference to the following examples and comparative examples, but the present invention is not limited to these. Unless otherwise specified, “parts” means “parts by weight”. Items marked with an asterisk (*) are manufactured by San-Ei Gen FFI Co., Ltd.

Preparation Example 1 Preparation of readily soluble granule composition (1)
In accordance with the formulations shown in Tables 1 and 2, 500 g of a water-soluble polymer preparation (Bistop * D-3000-DF-C *, xanthan gum) and dextrin powder mixture were charged into a fluidized bed granulator. Fluidized bed granulation was performed using the described binder to obtain an easily soluble granule composition (Examples 1 to 6). On the other hand, fluidized bed granulation was performed using a solution containing water or dextrin as a binder as a comparative example, and the easily soluble granule compositions of comparative examples 1 and 2 were obtained. In Comparative Examples 3 to 7, a water-soluble polymer formulation and dextrin were mixed with a powder mixture prepared by appropriately adding sodium malate, sodium tartrate, sodium fumarate, sodium succinate, or sodium acetate, using water as a binder. Prepared by fluidized bed granulation. Specifically, the powder was put into a granulator, hot air was sent from below to cause the powder to flow. In this fluidized bed, the binder liquids listed in Tables 1 and 2 are nozzle-jetted, and the binder liquid is uniformly attached to the powder surface to form agglomerated particles, which are dried. Examples 1 to 6 and Comparative Examples 1-7 granules were prepared. 150 g of the binder liquid was sprayed on 500 g of the powder mixture.

Experimental Example 1 Water Solubility Test 100 ml of ion-exchanged water at 20 ° C. was prepared in a 200 ml beaker. To each beaker, 2 g of the easily soluble granule composition prepared in Preparation Example 1 (Examples 1 to 6 and Comparative Examples 1 to 7) was added, allowed to stand for 10 seconds, and then stirred for 30 seconds with a spatula. The condition was observed. Tables 1 and 2 show the state of ramping after stirring. The evaluation was performed according to the criteria in Table 3.

  From Tables 1 and 2, the use of aqueous solution containing sodium malate, sodium tartrate, sodium lactate, sodium fumarate, sodium succinate, or sodium acetate as a binder makes the water-soluble polymer granulated, thereby remarkably reducing lumps. Even when xanthan gum, which is easy to occur, was used, there was no lumps when dissolved in water, and it became an easily soluble granule composition showing very good dispersibility (Examples 1 to 6). On the other hand, when ion-exchanged water or a 10% dextrin solution is used as the binder (Comparative Examples 1 and 2), the ramping of the water-soluble polymer cannot be prevented, and the readily soluble granule composition is dissolved in water. In this case, a large amount of lumps were formed, and the lumps once formed did not readily dissolve even with strong stirring. Moreover, even when the same (A) sodium malate, sodium tartrate, sodium fumarate, sodium succinate, or sodium acetate is used, it is simply mixed with a water-soluble polymer and ion-exchanged water is used as a binder. When an easily soluble granule composition is prepared by granulation (Comparative Examples 3 to 7), the ramping of the water-soluble polymer in water cannot be prevented, and a large amount of lumps are generated and easily in water. It was not possible to prepare a readily soluble granule composition that dissolves. From the above results, malic acid, tartaric acid, lactic acid, fumaric acid, succinic acid or acetic acid, or salts thereof are effective in preventing the ramping of the water-soluble polymer, and the effect is significant only when added to the binder liquid. I found out.

Preparation Example 2 Preparation of readily soluble granule composition (2)
According to the formulation shown in Table 4, an easily soluble granule composition was prepared. Specifically, 500 g of a powder mixture of carrageenan and dextrin is put into a fluidized bed granulator, fluidized bed granulation is performed in the same manner as in Preparation Example 1 using a 10% sodium malate solution as a binder, and easily soluble granules A composition was obtained (Example 7). 150 g of binder liquid was sprayed on 500 g of the powder mixture.

Experimental Example 2 Solubility test in concentrated liquid food 100 ml of concentrated liquid food (pH 7, fat content 5.6%, mineral content 0.6%) at 20 ° C. was prepared in a 200 ml beaker. After adding 1 g of the easily soluble granule composition of Example 7 prepared in Preparation Example 2 to the concentrated liquid food, the mixture was stirred with a spatula for 1 minute, and the state of the stirred solution was observed. On the other hand, fluidized bed granulation was performed using a solution containing ion-exchanged water or dextrin as a binder as a comparative example, and the readily soluble granule compositions of Comparative Examples 8 and 9 were obtained. The evaluation was performed by measuring the viscosity of the ramping after stirring and the viscosity developing property every 5 minutes in the same manner as in Experimental Example 1, and the results are shown in Table 4 and FIG. The viscosity was measured under the condition of a B-type rotational viscometer and 12 rpm.

  From Table 4, by preparing and granulating carrageenan using a solution containing sodium malate as a binder so that the amount of sodium malate added is 10 parts by weight per 100 parts by weight of carrageenan (easily soluble granules Even when added to the composition, Example 7), a concentrated liquid food having a high fat content and ionic concentration, the water-soluble polymer showed very good dispersibility without causing ramping. Furthermore, the easily soluble granule composition of Example 7 had the advantage that when it was added to a concentrated liquid food, it reached a certain viscosity and the time required for the viscosity to stabilize was short. On the other hand, in Comparative Examples 8 and 9, in which carrageenan was granulated using ion-exchanged water or dextrin solution as a binder solution, a ramping frequently occurs when added to a concentrated liquid food, and an easily soluble granule composition that dissolves easily in the concentrated liquid food The product could not be prepared.

  The present invention prevents ramping when a water-soluble polymer having the property of thickening and / or gelling is added to a liquid, easily dissolves the water-soluble polymer in the solution, and thickens or gels the liquid. Can be made. In particular, because it can prevent the ramping of water-soluble polymers even under weak stirring conditions such as hand stirring, it can be easily prepared for patients and caregivers who are difficult to chew and swallow. Supplementary compositions can be provided.

When adding granules (Example 7, Comparative Example 8 and Comparative Example 9) of granulated carrageenan using 10% sodium malate solution, ion-exchanged water, and 10% dextrin solution as binder liquids, respectively, It is a graph which shows a time-dependent change of the viscosity of a thick liquid food.
