Description

  The present invention relates to a method for producing high-concentration sucrose liquid sugar in which precipitation of sucrose crystals is suppressed, a high-concentration sucrose liquid sugar produced by the production method, and a method for inhibiting crystal precipitation of high-concentration sucrose liquid sugar.

  Saccharides such as sucrose and glucose are indispensable ingredients for the production of a wide variety of foods, and there are a wide variety of sugars used in various forms such as crystalline, liquid, and powder. . Particularly in recent years, saccharides prepared in a liquid state, so-called liquid sugars, have been used because of their excellent convenience in use.

  This liquid sugar is excellent in fluidity, and is used as a food such as syrup itself, or widely used for the purpose of imparting sweetness to various foods. Because of this high convenience of liquid sugar, various liquid sugar purification methods have been proposed (see Patent Documents 1 and 2).

  However, liquid sugars containing sucrose and the like have a problem that crystals of sucrose precipitate when stored for a long period of time or at room temperature. And the crystal precipitation becomes so remarkable that the concentration of sucrose contained in liquid sugar becomes large, and it is known that a crystal | crystallization precipitates notably more specifically in Bx67 or more.

  As a high-concentration liquid sugar currently manufactured and sold, there is maltose syrup (contains 75% by weight of maltose) of about Bx70 containing maltose at a high concentration, but maltose contained in this is produced using starch as a raw material. It is inferior in terms of sweetness and flavor as compared with liquid sugar made of sucrose.

  Therefore, a high-concentration sucrose liquid sugar containing sucrose at a high concentration is desired rather than containing sugar produced from starch or the like, but it is currently used for commercial use because of the above-mentioned problem of crystal precipitation. The sucrose liquid sugar currently used is Bx67-68, and a higher concentration sucrose liquid sugar has not been used.

  On the other hand, in the case of sucrose liquid sugar having a concentration of Bx67 to 68 or lower, since the ratio of the contained water becomes large, microorganisms and the like are likely to propagate and the quality may be deteriorated. It is not commercialized for consumer use.

  The disadvantages of these liquid sugars are that, as described above, liquid sugars with high convenience have been used in a wide variety of foods. It has become a big problem in using it.

Japanese Patent Laying-Open No. 2005-087141 JP 2005-295916 A

  Therefore, the present invention has been proposed in view of such circumstances, and a method for producing a high-concentration sucrose liquid sugar that suppresses sucrose crystal precipitation in high-concentration sucrose liquid sugar and prevents the growth of microorganisms and the like, and It is an object of the present invention to provide a high concentration sucrose liquid sugar and a method for suppressing crystal precipitation of the high concentration sucrose liquid sugar.

  According to the present invention, it is possible to produce a high-concentration sucrose liquid sugar that can suppress the precipitation of sucrose crystals and can inhibit the growth of microorganisms.

It is a figure explaining the water activity (Aw) which shows the amount of water required for the propagation of microorganisms and enzyme activity. It is process drawing which shows the 1st example of a manufacturing process regarding the manufacturing method of high concentration sucrose liquid sugar. It is process drawing which shows the 2nd example of a manufacturing process regarding the manufacturing method of high concentration sucrose liquid sugar.

  Hereinafter, specific embodiments of the method for producing high-concentration sucrose according to the present invention will be described in detail with reference to the drawings.

  The method for producing a high-concentration sucrose according to the present embodiment is a method for producing a sucrose liquid sugar comprising 20 to 27% by weight of water and a solid content containing sucrose, and is contained in the sucrose-containing solution in the solid content. The fructooligosaccharide is contained so that the amount becomes a predetermined amount.

  The sucrose liquid sugar produced in this production method contains water in a proportion of 20 to 27% by weight of the total sucrose liquid sugar, and therefore contains a high concentration of sucrose containing a solid content of 73% by weight or more in the liquid sugar. Liquid sugar.

  More preferably, water is contained in an amount of 25 to 27% by weight, and fructooligosaccharide is contained so that the content in the solid content is 13 to 20% by weight. The solid content used herein means a high-concentration sucrose liquid sugar composition other than water, and means the weight of the high-concentration sucrose liquid sugar composition obtained when the high-concentration sucrose liquid sugar is dried and solidified.

  Here, fructooligosaccharides are oligosaccharides in which one or more fructose molecules are bonded to sucrose (sucrose), and 3-5 saccharides are the main components. Specifically, for example, trisaccharide in fructooligosaccharide is Glu-Fru-Fru (1-kestose), tetrasaccharide is Glu-Fru-Fru-Fru (nystose), and pentasaccharide is Glu-Fru. -Fru-Fru-Fru (1-fructosyl nystose). Glu represents glucose and Fru represents fructose.

  This fructooligosaccharide is contained in a large number of plants such as honey, asparagus, onion, potato, etc., and together with the oligosaccharide, it is a low-calorie carbohydrate, for example, to promote the growth of lactic acid bacteria and bifidobacteria, It is known to have excellent functions such as a promoting action of a microbial group, a suppressive action of pathogenic bacteria, and enhancement of immunity. In addition, fructooligosaccharide is an indigestible sugar that is difficult to carve and is not digested by in vivo digestive enzymes. Because it does not affect the value, it is used as a therapeutic diet for diabetics. These properties are not found in monosaccharides and sucrose.

  In addition, fructooligosaccharides act on sucrose (sucrose) in an aqueous solution by, for example, existing fructosyltransferases produced from cells of the genus Aureobacidium (sp) and Aspergillus (sp). Manufactured. Alternatively, it is produced by reacting fructosyltransferase with sucrose as a substrate by mixing these microorganisms with sucrose in an aqueous solution. In this way, fructosyltransferase is allowed to act on a sucrose solution, thereby generating inulin-type fructooligosaccharides in which fructose is β-1,2 linked to fructose constituting sucrose as a substrate.

  In the manufacturing method of the high concentration sucrose liquid sugar according to the present embodiment, the content in the solid content of the high concentration sucrose liquid sugar containing 20 to 27% by mass of water is 10 to 20% by weight, The fructooligosaccharide is contained in the sucrose-containing solution. More preferably, in the production of a high-concentration sucrose liquid sugar containing 25 to 27% by weight of water, the fructooligosaccharide is contained so as to be 13 to 20% by weight as the solid content.

  Thus, producing a high-concentration sucrose liquid sugar that effectively suppresses the precipitation of sucrose crystals contained at a high concentration by setting the content of fructooligosaccharide in the solid content to 10% by weight or more. By making the content 20% by weight or less, a high-concentration sucrose liquid sugar that does not impair the original sweetness and flavor of sucrose can be produced.

  In addition, since a high-concentration sucrose liquid sugar in which sucrose crystal precipitation is suppressed can be produced, it can be used for various purposes such as foods and medical use. Moreover, since the water | moisture content contained in the said sucrose liquid sugar is 27 weight% or less, propagation of microorganisms can be inhibited significantly and it can preserve | save in a good-quality state under normal temperature.

  Furthermore, since the fructooligosaccharides to be contained are oligosaccharides produced by the action of enzymes using sucrose as a substrate as described above, the original flavor and sweetness of sucrose liquid sugar are not impaired. High-quality high-concentration sucrose can be produced. In addition, as described above, fructooligosaccharides have a wide variety of properties that sucrose does not have. Therefore, sucrose liquid sugar produced by the method for producing high-concentration sucrose liquid sugar according to this embodiment is used. By using it, it is possible to enjoy properties not found in sucrose, such as an intestinal activity promoting effect and an immune enhancing effect.

  In the method for producing high-concentration sucrose liquid sugar according to the present embodiment, the content of fructooligosaccharide in the solid content is 10 to 20 wt.% In brown liquor purified through the carbonation saturation step in the production process of sucrose liquid sugar. % Fructooligosaccharide is added and contained. As described above, fructooligosaccharides may be generated and contained by acting an enzyme agent containing fructosyltransferase. That is, in the manufacturing process of sucrose liquid sugar, after raw sugar is washed and dissolved, brown liquor purified by carbonation saturation is used as a raw material, and an enzyme agent containing fructosyl transferase is allowed to act to contain it in brown liquor. By making a part of the sucrose to be fructooligosaccharide, the content of fructooligosaccharide in the solid content may be 10 to 20% by weight.

  The fructooligosaccharide to be added is not particularly limited, and commercially available fructooligosaccharides that are generally available can be used. For example, Nippon Oligo Fructo-oligosaccharide manufactured by Nihon Oligo Co., Ltd., MS Mayoligo manufactured by Meiji Seika Co., Ltd.

  In addition, the fructooligosaccharide to be added may be separately produced by reacting fructosyltransferase with a sucrose solution. As a production method, it can be produced by, for example, a batch method or a fixed continuous method. Specifically, in the batch method, a fructo-oligosaccharide can be obtained by mixing a microorganism producing fratosyl transferase with a sucrose solution and reacting the fraucosyl transferase with a sucrose solution as a substrate. . On the other hand, in the fixed continuous method, microorganisms or enzymes are immobilized on a carrier (base material), and sucrose as a substrate is brought into contact with the base material to react with the microorganisms or enzymes to obtain fructooligosaccharides. it can. Although it does not specifically limit as reaction conditions in the production | generation method using these systems, For example, it hydrolyzes on 150-250 degreeC temperature conditions.

  As described above, in the method for producing high-concentration sucrose liquid sugar, in one step of the method for producing sucrose liquid sugar, fructooligosaccharide is generated and contained by adding fructo-oligosaccharide or acting fructosyltransferase. Yes. As a result, it is possible to suppress the precipitation of sucrose crystals as described above and prevent the growth of microorganisms by an easy process without preparing a special manufacturing apparatus or the like, and can be stably stored at room temperature. Concentrated sucrose sugar solution can be produced.

  Hereinafter, the method for producing sucrose liquid sugar according to the present embodiment will be described in more detail.

<Water content of high-concentrated sucrose liquid sugar and water activity of microbial propagation>
Prior to detailed description, the relationship between the amount of water in sucrose liquid sugar and microbial growth will be described first. In the method for producing sucrose liquid sugar according to the present embodiment, the amount of water contained in the sucrose liquid sugar is set to 20 to 27% by weight. If the water content is less than 20% by weight, it is difficult to produce the sucrose liquid sugar. Therefore, the sucrose liquid sugar can be easily produced by setting the water content to 20% by weight or more. On the other hand, by setting the water content to 27% by weight or less, the propagation of microorganisms is effectively prevented as described below.

  FIG. 1 below shows the water activity (Aw) indicating the amount of water necessary for microbial growth and enzyme activity.

  As shown in FIG. 1, it can be seen that general bacteria can reproduce in a water environment having an Aw value of about 0.91 or more, and general yeasts have a water activity of about 0.88 or more, and also exhibit enzyme activity. On the other hand, in the case of general mold, it can be propagated in a water environment having an Aw value of 0.80 or more, which is lower in water activity than general bacteria and general yeast, and shows an enzyme activity (corporation corporation) Confectionery Technical Center, New Material for Confectionery No7; 19 (1987)).

  In the case of a saturated solution of 67.4% by weight of sucrose (containing about 25% by weight of water), the Aw value is about 0.85. With this sucrose liquid sugar, breeding of general bacteria and general yeasts Although it is possible to prevent, general mold may breed.

  Until now, in the production process of sucrose liquid sugar, in order to prevent the growth of these microorganisms and the decay of liquid sugar, always clean the inside of the storage tank and purify the air flowing in during storage. At the same time, a method is employed in which sucrose liquid sugar is irradiated with ultraviolet rays with an ultraviolet germicidal lamp to prevent the growth of microorganisms while constantly circulating the liquid sugar inside the storage tank or between the storage tank and the external circulation pipe. However, this treatment alone cannot sufficiently prevent the growth of microorganisms due to the relationship of ultraviolet transmittance and the like.

  Therefore, in the present embodiment, the sucrose liquid sugar is produced so that the water content is 27% by weight or less. In general, when the water content in the high-concentration sucrose liquid sugar is 27% by weight or less, the water activity value is lower than Aw0.80 and is about Aw0.79 or less. Microbial growth is suppressed and enzyme activity is lost. Further, by further reducing the water content, for example, by setting the water content to 25% by weight, the water activity value is further reduced, and the propagation of microorganisms can be more effectively suppressed. In the method for producing a high-concentration sucrose liquid sugar according to the present embodiment, the amount of water in the sucrose liquid sugar is 27% by weight or less, thereby effectively preventing the growth of microorganisms and rot of the sucrose liquid sugar. A high concentration of sucrose liquid sugar that is prevented is produced.

  From the viewpoint of preventing the growth of microorganisms and producing a high-concentrated sucrose liquid sugar, the water content is set to 27% by weight or less, and the solid content concentration containing sucrose contained in the sucrose liquid sugar is set to 73% by weight or more. In this case, there is a problem that crystals of contained sucrose precipitate. However, in the method for producing a high-concentration sucrose liquid sugar according to the present embodiment, fructooligosaccharide is contained so as to be 10 to 20% by weight in the solid content. Thereby, while suppressing the water activity of sucrose liquid sugar and preventing the proliferation of microorganisms, precipitation of sucrose crystals can be suppressed and a high concentration sucrose liquid sugar can be produced.

<Manufacture of high-concentration sucrose liquid sugar>
The method for producing a high-concentration sucrose according to the present embodiment is a method for producing a sucrose liquid sugar comprising 20 to 27% by weight of water and a solid content containing sucrose, and is contained in the sucrose-containing solution in the solid content. The fructooligosaccharide is contained so that the amount is 10 to 20% by weight.

  The solvent of the solution containing a high concentration of sucrose is preferably water, but ethyl alcohol, glycerin, propylene glycol and the like can also be used. Moreover, you may add another food additive in the range which does not prevent the effect in this Embodiment. Specifically, flavorings, coloring agents such as β-carotene, anato pigment, purple corn pigment, mustard extract, wasabi extract, kojic acid and other food preservatives, protein extract, polylysine, sorbic acid, etc. Preservatives, quercetin, enzyme-treated isoquercitrin, antioxidants such as enzyme-treated rutin, carrageenan, xanthan gum, tragacanth gum, pectin, glucomannan, raw starch, modified starch, hemicellulose, water-soluble soybean polysaccharide, microcrystalline cellulose, Thickeners and gelling agents such as fermented cellulose, microfibrous cellulose, methylcellulose, ethylmethylcellulose, gum arabic, aspartame, sucralose, licorice extract (glycyrrhizin), acesulfame potassium, aritem, neotame, thaumatin, saccharin, saccharin sodium, saccharin Phosphorus Calcium, stevia extract, high intensity sweetener Stevia powder such as citric acid, fumaric acid, pH adjusting agents such as succinic acid, other extracts can be exemplified vitamins, minerals and the like.

  This high-concentration sucrose liquid sugar can be produced by adding fructooligosaccharide to a sucrose-containing solution in a production process using a general raw material sugar. More specifically, the fructooligosaccharide is added to the brown liquor purified through the carbonic acid saturation step in the sucrose liquid sugar production step so that the content in the solid content is 10 to 20% by weight.

  In addition, you may make it produce fructooligosaccharide by making the enzyme agent containing fructosyltransferase act. In other words, in the manufacturing process of sucrose liquid sugar, after raw sugar is washed and dissolved, brown liquor purified by carbonation saturation is used as a raw material, and an enzyme agent containing fructosyltransferase is allowed to act on the brown liquor. A part of the sucrose contained may be fructooligosaccharide. Also in this case, an enzyme agent produced from the microbial cells producing fructooligosaccharides can be used.

  In this way, fructooligosaccharides are produced by adding a predetermined amount of fructooligosaccharides to brown liquor purified through the carbonation saturation step in the sucrose liquid sugar production process or by allowing an enzyme agent containing fructosyltransferase to act. The high-concentration sucrose liquid sugar that can effectively suppress the precipitation of sucrose crystals contained at a high concentration and does not change the flavor, sweetness, etc. can do.

  In addition, by adding fructooligosaccharide or acting an enzyme agent containing fructosyltransferase to brown liquor purified through the carbonation saturation step in the sucrose liquid sugar production process, It is possible to produce high-quality sucrose liquid sugar that retains the richness and flavor of a certain sugarcane. Further, since brown liquor is a sugar solution before complete purification, it contains more mineral components and the like than fine liquor, which is the final refined sugar solution of crystalline sucrose or liquid sugar. For this reason, for example, fructooligosaccharides containing a large amount of mineral components are produced by allowing an enzyme agent containing fructosyltransferase to act on brown liquor to produce high-concentration sucrose liquid sugar rich in mineral components. Can do. Furthermore, since brown liquor has a small amount of energy used in the production process, by performing the above-described treatment on the brown liquor, it is possible to reduce production energy and carbon dioxide gas.

  FIG. 2 is a process diagram showing a first production process example relating to the production of the high-concentration sucrose liquid sugar according to the present embodiment. In addition, in this manufacturing process, the flow which manufactures the high concentration sucrose liquid sugar of Bx75 is shown. Here, Bx is Brix% measured using a refractometer and serves as an index indicating the percentage of solid content in the sucrose liquid sugar.

  First, the raw sugar transported from the raw sugar warehouse is washed (1-1). As raw materials of the sucrose liquid sugar to be produced, 63% by weight of sucrose as a raw sugar and 37% by weight of water as a solvent are mainly used. In this sugar-washing step, a fixed ratio of molasses is added to the raw sugar, and the raw sugar is mixed into a semi-fluid mixture by kneading while heating. Sugar) and nectar. By this sugar washing step, impurities (pigment substances, inorganic salts, etc.) adhering to the surface of the raw sugar crystals are removed. Then, the lorica is purified by adding warm water or sweet water to the sugar-washing and completely dissolving it.

  Once the raw liquor is refined, next, a certain ratio of lime milk is continuously added and fed into the carbonated saturated layer, and carbon dioxide is blown to produce calcium carbonate (1-2). In this carbonic acid saturation step, it is included in calcium carbonate in order to easily remove the pigment substances and inorganic salts contained in the low liquor. Then, impurities are removed by this carbonation saturation step and filtered to purify the brown liquor of Bx63.

  When brown liquor is purified in this way, the brown liquor purified using an evaporator is concentrated (1-3). In this concentration step, the content ratio of sucrose is increased to obtain Bx75 brown liquor. That is, the brown liquor contains 75% by weight of sucrose and 25% by weight of water.

  In the method for producing high-concentration sucrose according to the present embodiment, fructooligosaccharides are added to the Bx75 brown liquor thus purified. This fructooligosaccharide is Bx75, and it is added to a Bx75 brown liquor containing 25% by weight of water and 75% by weight of solids so that the content in the solids is 10 to 20% by weight. The fructooligosaccharide to be added is not particularly limited, and generally available fructooligosaccharides can be used.

  In the method for producing a high concentration sucrose liquid sugar according to the present embodiment, fructooligosaccharide is added to brown liquor as described above to purify the high concentration sucrose liquid sugar. Although not shown, the purified high-concentration sucrose liquid sugar is subjected to a heat sterilization treatment, for example, under a temperature condition of 98 ° C. for 5 minutes, filtered and then cooled to about 60 ° C. and filled.

  Also in this manufacturing process, the inside of the storage tank is always washed cleanly in accordance with a regular method to purify the air flowing in during storage, and the liquid sugar is contained inside the storage tank or between the storage tank and the external circulation pipe. The liquid sugar is irradiated with ultraviolet rays with an ultraviolet germicidal lamp, and the microorganisms are prevented from growing.

  In the first example of the manufacturing process, granulated sugar or the like is mixed and dissolved in the brown liquor concentrated in the concentration process (1-3), and the mixed dissolution process of adjusting the concentration is performed. Good. Specifically, in the above production process, brown liquor purified in the carbonation saturation process (1-2) is used, for example, Bx70 (70% by weight of sucrose, water, using an evaporator in the concentration process (1-3)). Concentrate to 30% by weight). Then, granulated sugar is added to the concentrated brown liquor (Bx70), mixed and completely dissolved to purify Bx75 brown liquor (mixing and dissolving step). In this mixing and dissolving step, the amount of granulated sugar added is 83% by weight of brown liquor and 17% by weight of granulated sugar. Thus, in the mixing and dissolving step, for example, granulated sugar may be added to Bx70 brown liquor to adjust the concentration, and fructooligosaccharide (Bx75) may be added to Bx75 brown liquor.

  As described above, in the method for producing high-concentration sucrose according to the present embodiment, the brown liquor purified through the carbonation saturation step in the sucrose liquid sugar production step has a solid content of 10 to 20% by weight. The fructooligosaccharide is contained so that Thereby, precipitation of a sucrose crystal can be suppressed even if it is a liquid sugar containing a high concentration of sucrose of Bx70 or higher. Moreover, by setting the water content to 27% by weight or less, it is possible to effectively prevent the growth of microorganisms.

  In the manufacturing process of the above high-concentration sucrose, fructooligosaccharide was added to brown liquor concentrated to Bx75, but an enzyme agent containing fructosyltransferase was allowed to act on purified brown liquor to produce fructooligosaccharide. The fructooligosaccharide may be contained in the high-concentration sucrose liquid sugar by the generation. Specifically, a process for producing a high-concentration sucrose liquid sugar in which an enzyme agent containing fructosyltransferase is allowed to act on brown liquor will be described with reference to FIG.

  FIG. 3 is a process diagram showing a second production process example regarding the production method of the high-concentration sucrose liquid sugar according to the present embodiment. In addition, this 2nd example of a manufacturing process manufactures high concentration sucrose liquid sugar of Bx75.

  As shown in FIG. 3, the sugar washing step (2-1), the carbonic acid saturation step (2-2), and the concentration step (2-3) are performed in the same manner as the manufacturing step shown in FIG. 2 described above. Bx75 brown liquor is purified.

  Next, the mixed and dissolved brown liquor is transferred to an oligosaccharification reaction tank, and a part of the sucrose contained in the brown liquor is converted into fructo-oligosaccharide (2-4). Specifically, in this oligosaccharification step, 2 ml of 1N hydrochloric acid (HCl) is added to 1 kg of sucrose, and 2 KU of fructosyltransferase is added to 1 kg of sucrose, in the brown liquor transferred to the oligosaccharification reaction tank. . In this manner, fructosyl saccharides composed mainly of 1-kestose and nystose with 1 to 3 fructose bound thereto are produced by allowing fructosyltransferase to act on sucrose. As reaction conditions at this time, it is made to act on temperature conditions of pH 5-7, 55-60 degreeC for 4 hours, for example.

  As the enzyme agent containing fructosyltransferase, for example, an enzyme produced from cultured cells obtained by liquid culture of Aureobacidium sp. Can be used. In addition, regarding a method for producing fructooligosaccharides using cultured cells obtained by liquid culture of the genus Aureobasidium, JP-A-60-27395 (Japanese Patent Application No. 58-134661), JP-A No. JP-A-61-146192 (Japanese Patent Application No. 59-266963) and JP-A-60-41497 (Japanese Patent Application No. 58-148583).

  In this way, by causing an enzyme agent containing fructosyltransferase to act on Bx75 brown liquor, part of the sucrose becomes fructooligosaccharide, and high-concentration sucrose liquid sugar containing fructo-oligosaccharide is purified. In addition, as a component composition in solid content when the enzyme agent containing fructosyltransferase is made to act on the said reaction conditions and manufacturing high concentration sucrose liquid sugar (Bx75), oligosaccharides 11.8 weight%, kestose 10 0.7% by weight, 1.1% by weight of nystose, 83.5% by weight of sucrose, and 4.7% by weight of glucose.

  In the second manufacturing process example, as in the first manufacturing process example, brown liquor is concentrated to, for example, Bx70 in the concentration process (2-3), and granulated sugar or the like is added to the brown liquor. You may make it pass through the mixing melt | dissolution process which adjusts a density | concentration so that it may become Bx75 by mixing and dissolving.

  In addition, the first and second manufacturing process examples described above are specific examples, and are manufacturing process examples for manufacturing a high-concentration sucrose liquid sugar of Bx75, and are not limited thereto. Absent. For example, moderate heating and stirring may be optionally performed when adding fructooligosaccharides. In addition, it goes without saying that other reaction conditions and the like may be appropriately changed according to the amount of additive added.

  As described above in detail, in the method for producing sucrose liquid sugar according to the present embodiment, in the production process of sucrose liquid sugar comprising 20 to 27% by weight of water and solids containing sucrose, The fructooligosaccharide is contained so that the content in the solid content is 10 to 20% by weight. More preferably, water is contained in an amount of 25 to 27% by weight, and fructooligosaccharide is contained so that the content in the solid content is 13 to 20% by weight.

  According to the method for producing sucrose liquid sugar according to the present embodiment, the water activity of the water contained in the sucrose is reduced, so that it is possible to effectively prevent the growth of microorganisms and to reduce the water content to a high concentration. The sucrose liquid sugar can be produced. In addition, in the production process of this high-concentration sucrose liquid sugar, by containing a predetermined amount of fructooligosaccharide, sucrose crystal precipitation can be effectively suppressed, and the high-concentration sucrose liquid sugar is stored in a stable state at room temperature. It becomes possible to keep.

  Moreover, by using the high-concentration sucrose produced by the method for producing a high-concentration sucrose according to the present embodiment, which does not precipitate sucrose crystals and can be stored for a long period of time, various foods, pharmaceuticals, and quasi drugs are used. Etc. can be prepared.

  For example, vitamin / mineral drinks, milk drinks, lactic acid bacteria drinks, dairy products, fermented milk, acidic drinks, neutral drinks, coffee, tea, green tea, whey drinks, carbonated drinks, fruit drinks, fruit juice drinks, beer, cocktails and Chuhai Examples include alcoholic beverages such as health drinks, health drinks such as nutrition drinks, sports drinks, and yogurt drinks. In addition, foods manufactured from water-soluble raw materials, such as bread and confectionery such as bread, biscuits, strawberries, jelly, pudding, yogurt, sauces, dressings, liquid sweetener preparations, processed foods such as syrup, liqueur base, and ham Foods such as curry, stew and soup are also included. Furthermore, pharmaceutical compositions such as solutions, injections, drops, syrups, creams, ointments, lotions and the like can also be produced.

  Furthermore, as described above, in the method for producing high-concentration sucrose liquid sugar according to the present embodiment, by using a general raw material sugar, fructooligosaccharide is added to brown liquor purified through a carbonation saturation step. To manufacture. Alternatively, it is produced by producing and containing fructooligosaccharides by allowing an enzyme agent containing fructosyltransferase to act on sucrose. In this way, a high-concentration sucrose that can be stored for a long period of time without producing sucrose crystals can be produced simply by including a predetermined amount of fructooligosaccharide in one step of the method for producing sucrose liquid sugar. It can be manufactured by simple processing without preparing special equipment and manufacturing conditions.

  Furthermore, since the added fructooligosaccharide is a oligosaccharide produced by allowing fructosyltransferase to act on sucrose, it produces high-quality sucrose liquid sugar without compromising the original flavor and sweetness of sucrose liquid sugar. can do. This high-concentration sucrose liquid sugar can also enjoy various properties of fructooligosaccharides.

  It should be noted that the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.

  Hereinafter, specific examples of the present invention will be described. Note that the scope of the present invention is not limited to any of the following examples.

  In this example, in the production process of sucrose liquid sugar containing sucrose having concentrations of 73% by weight (Table 1), 75% by weight (Table 2), and 80% by weight (Table 3), The indicated amount of fructooligosaccharide was added, and the number of days until sucrose crystals were precipitated in the high-concentration sucrose liquid sugar produced was examined. The fructooligosaccharide content (% by weight) in the table means the content of the high-concentration sucrose liquid sugar in the solid content.

  In this experiment, fructooligosaccharides were purified from brown liquor purified through a carbonation saturation step for sucrose liquid sugars that were purified without adding fructooligosaccharides in the normal sucrose liquid sugar production process. Each high-concentration sucrose (sample) that was blended and purified at each blending amount shown in FIG. The purified high-concentration sucrose liquid sugar was sealed in a 500 ml test bottle and allowed to stand at room temperature, and the test bottle was turned upside down once a day, and then the lid was opened for 2 minutes for examination. Presence / absence of crystal precipitation was determined by naked eye judgment. In Tables 1 to 3 below, “−” indicates that no crystal precipitation was observed, and “×” indicates that crystal precipitation was observed. The Bx value of sucrose liquid sugar was measured with a hand-held refractory saccharide meter (N3, manufactured by Atago Co., Ltd.).

  As can be seen from the results shown in Table 1, in the high-concentration sucrose liquid sugar (samples 1 to 6) having a sucrose concentration of 73 wt% (Bx73, water concentration 27 wt%), in sample 1 to which fructooligosaccharide was not added, On the second day, sucrose crystals had already precipitated. On the other hand, in sample 2 in which fructooligosaccharide was added so that the content in the solid content was 10% by weight, sucrose crystals were slightly precipitated on the 20th day, but no fructooligosaccharide was added. It was found that it can be stored stably for a long period of time compared to Sample 1.

  In addition, in the samples 3 to 6 in which fructooligosaccharides were contained at 13% by weight, 15% by weight, 17% by weight, and 20% by weight, respectively, as the solid content, 73% by weight even on the 90th day No crystallization of sucrose contained at a concentration as high as% was confirmed, and it was found that it can be stably stored for a long time.

  Further, as can be seen from the results shown in Table 2, in the high-concentration sucrose liquid sugar (samples 7 to 12) having a sucrose concentration of 75% by weight (Bx75, water concentration 25% by weight), the sample 7 to which fructooligosaccharide was not added Then, on the second day, sucrose crystals had already precipitated. On the other hand, in sample 8 in which fructooligosaccharide was added so that the content in the solid content was 10% by weight, sucrose crystals were slightly precipitated on the 17th day, but no fructooligosaccharide was added. It was found that it can be stored stably for a long period of time as compared with Sample 7. In addition, in sample 9 in which fructooligosaccharide was added so that the content in the solid content was 13% by weight, sucrose crystals were slightly precipitated on the 27th day. It was found that crystals can be stored for a longer period of time while suppressing the precipitation of crystals.

  Further, in the samples 10 to 12 containing 15% by weight, 17% by weight, and 20% by weight of the fructooligosaccharide as a solid content, the concentration as high as 75% by weight was obtained even on the 90th day. No crystallization of sucrose contained in was confirmed, and it was found that it can be stored stably for a long time.

  Further, as can be seen from the results shown in Table 3, in the high-concentration sucrose liquid sugar (samples 13 to 18) having a sucrose concentration of 80% by weight (Bx80, water concentration 20% by weight), the sample 13 to which fructooligosaccharide was not added Then, on the second day, sucrose crystals had already precipitated.

  On the other hand, in sample 14 to which fructooligosaccharide was added to a solid content of 10% by weight and sample 15 to be added to 13% by weight, sucrose was slightly increased on the fourth day. However, it was found that the sucrose crystals precipitated at a high concentration can be suppressed as compared with the sample 13 to which no fructooligosaccharide was added.

  Further, in the sample 16 in which fructooligosaccharide was added so that the content in the solid content was 15% by weight, the precipitation of sucrose crystals was confirmed slightly on the fifth day, and the sample was added so as to be 17% by weight. In No. 17, sucrose crystals were slightly precipitated on the 7th day, and in Sample 18 added so as to be 20% by weight, the sucrose crystals were slightly precipitated on the 21st day. In this way, in the high concentration sucrose having a sucrose concentration of 80% by weight, by increasing the content of the fructooligosaccharide in the solid content, a high concentration that can be stored in a good quality state for a long time without precipitating sucrose crystals. It has been found that sucrose liquid sugar can be produced.
