Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a calcium saccharate composition that can be widely used in the fields of food and civil engineering and construction materials, and a method for producing the same.

[Problems to be solved by conventional techniques and inventions] Conventionally,
Kansui is a food additive that is added to flour.
is a mixture of potassium carbonate, soda carbonate, and phosphate, and has a high pH that makes it difficult to digest. Therefore, Chinese noodles that do not use ``kansui'' began to be manufactured. However, ``kansui'' also has the effect of improving the shelf life of the noodles, so ``kansui'' is used in most Chinese noodles.

In addition, Chinese noodles have the disadvantage that the noodles ``spread'' during the taste, and various additives are used to make noodles that do not have ``spreadiness''. The texture also greatly affects the taste.

However, since no single type of food additive has been found that satisfies the above objectives, the current situation is that several types of food additives are used to meet the objectives.

Therefore, it would be very convenient to have one type of food additive that has several purposes, and there is a desire for one that is safe and functional.

These problems are not limited to Chinese noodles, but are also the same in other @ types, and are a consensus demand in the industry for udon, soba, etc., as well as processed wheat products and processed rice flour products.

In other words, in today's food industry, more advanced products are required in order to improve product distribution and taste, so new products must be introduced into the market one after another.Therefore, new food additives are required. ing.

In addition, diatomaceous earth, white clay, and volcanic ash, which are conventional silicic acid-containing materials,
In the reaction with quicklime, it is known that the reaction activity of the silicic acid-containing substance and quicklime greatly affects productivity. Therefore, special quicklime with controlled hydration is manufactured. However, since the initial strength is greatly affected by the composition of the CaO-5iO□-based compound, productivity similar to that of cement products cannot be expected. This is because the conventional method only controls the hydration of quicklime, and efficient synthesis of CaO-5iO2 compounds is secondary. For this reason, a method of heat curing is used to generate demolding strength.

Therefore, in order to solve this problem, it is necessary not only to control the water compatibility of quicklime, but also to find conditions that increase the solubility of quicklime in water and achieve supersaturation.

Furthermore, calcium chloride can no longer be used due to the problem of corrosion of reinforcing steel, and there is a need for an alternative cement quick-setting agent. Calcium nitrate, calcium sulfite, calcium thiosulfate, formic acid, calcium acetate, etc. are known as substitutes for calcium chloride, but at present there is no cement l-2 or sticky agent that can replace calcium chloride. .

The problem with cement quick setting agents is to obtain a cured product with high rising strength after a certain period of time with a small amount.For this purpose, calcium aluminates such as Cl2A7 and C11A7CF2 are preferable, but they are expensive.

A liquid quick-setting agent different from the calcium aluminate powder described above is also required. Therefore, it is necessary to search for a new calcium salt that is not a known substance. It is known that when added to cement, sugar becomes calcium saccharate, which acts as a retardant in small amounts and causes rapid setting in large amounts.

Moreover, it has not been put into practical use because it causes a decrease in strength.

Calcium saccharate is only well known from sucrose, and other #I! Currently, very little is known about the species. Therefore, it has almost no physical properties or uses.

Therefore, various I! There is a need to synthesize calcium saccharates of the same type, find their uses and new manufacturing methods, and provide them to industry.

[Means to solve the problem]

The present inventors have completed the present invention as a result of intensive research to solve the above problems.

That is, the present invention provides a calcium saccharate composition obtained by reacting slaked lime or quicklime with sugars, a method for producing the same, a food additive and a cement admixture comprising this calcium saccharate composition, and furthermore, a calcium saccharate composition obtained by reacting slaked lime or quicklime with a sugar. The present invention provides a method for producing calcium silicate, which is characterized by reacting a silicate raw material with quicklime or lime in the presence of a composition.

First, the case where the calcium salt/hexalate composition of the present invention is used as a food additive will be described.

It has already been mentioned that "Kansui" is used for wheat flour, but when the calcium saccharate composition of the present invention is used instead of "Kansui", noodles having characteristics not found in the past can be obtained. The reason for this is that the calcium saccharate composition is alkaline, similar to Kansui, and it reacts with the pigment in the flour to turn it yellow, and the starch is pregelatinized, which improves its spreadability, elasticity, and stiffness. arise. Up to this point, it is the same as "Kansui", but if it is boiled noodles, "
There is a big difference between noodles made with "Kansui" and boiled noodles made with a calcium saccharate composition. Noodles using ``Kansui'' have a strong alkaline taste and swell quickly. In other words, it grows quickly. This rapid growth greatly affects the commercial value of boiled noodles, and is mostly the reason why the taste of ramen changes during eating. As a countermeasure, cornstarch, alcohol, gluten,
Egg white, agar, gelatin, etc. are added to prevent it from spreading.

Noodles using the calcium saccharate composition of the present invention have less elongation and are slower to swell in soup than noodles containing the above-mentioned additives. Also, the alkaline odor is weak,
You can get noodles with no taste. It has a long shelf life and can be stored in a household refrigerator for up to 7 days.

The calcium saccharate composition of the present invention is slaked lime or quicklime Uni-IJ! It is a product obtained by reacting one or a mixture of two or more of the following saccharose, lactose, maltose, raffinose, dextrin, glucoheptose, glucose, mannose, galactose, fructose, arabinose, erythrose, and glyceraldehyde, and has similar physical properties. polyhydric alcohols, healthitol, sorbitol, arabitol, erythritol, glycerol, ethylene glycol, propylene glycol or a mixture of two or more thereof, and use the mixture with one or a mixture of two or more of the above saccharides. Also good.

Although these can be synthesized by a wet method, it has been found that when pulverized and mixed with quicklime in the presence of a small amount of water, it is easy to react and synthesize calcium saccharate & [l parabolite.

This reaction can also be obtained by mixing fine powder or liquid of sugars or polyhydric alcohols with fine powder of quicklime. Moreover, the reaction equivalent of sugar or polyhydric alcohol to quicklime varies depending on the sugar or polyhydric alcohol, and the reaction itself is an addition reaction, so a perfect equivalence relationship cannot be established.

Therefore, it is necessary to have an excess of either sugars, polyhydric alcohols, or quicklime. In other words, this is the reason for the calcium saccharate composition.

For example, sucrose (sucrose, rock sugar, granulated sugar,
Even with white sugar, granulated sugar, and white sugar (F'), there is a slight difference in O in the reaction equivalent with quicklime depending on the manufacturing method and refining, but the amount is 80
Parts by weight: 20 parts by weight of quicklime.

For glucose, the ratio is 80 parts by weight of anhydrous crystals: 25 parts by weight of quicklime.

The ratio is 80 parts by weight for maltose and 20 parts by weight for quicklime.

In this way, regardless of monosaccharide or polysaccharide, the reaction ratio is approximately 4:
The reason why the weight ratio is 1 (weight ratio) is considered to be that Ca"" ions are crosslinked with active hydrogen of sugars.

To synthesize such a calcium saccharate composition, highly purified sugars such as granulated sugar, rock sugar, super/M sugar, and maltose are suitable.

In particular, for products other than ramen, such as radon and buckwheat, which do not like coloring, choose a color that does not discolor with alkali.

Since these saccharides need to be reacted with quicklime at low temperatures, the best manufacturing method is to pulverize both and mix and react.

The reaction ratio is preferably in the range of saccharides:quicklime -42 to 45:10 (weight ratio), and a composition with an excess of saccharides improves the solubility of quicklime in water. The signature of the reaction is 50g.
The reaction is terminated when the sugar is dissolved in 200 cc or more of water and the sweetness of the sugar disappears.

This composition dissolves well in water and can also be used as an aqueous solution. The basic recipe for ramen is as follows.

<Calcium saccharate formulation> Semi-strong flour 100 parts by weight water
45 Calcium Satsu Colored 1.25 Salt
6 parts by weight Kukansui formula> Semi-strong flour 100 parts by weight water
45 Kansui
1.0 salt
6. When used for udon and buckwheat, use calcium saccharate such as maltose and add it in an amount that avoids color development due to pigments of 0.1% by weight or less.

The amount of the calcium saccharate composition of the present invention added is 0.5 to 5 parts by weight per 100 parts by weight of wheat flour for ramen noodles;
Preferably it is 0.8 to 3 parts by weight, and for radon and buckwheat, it is 0.01 to 0.01 parts by weight per 100 parts by weight of wheat flour or buckwheat flour.
3 parts by weight, preferably 0.05 to 0.2 parts by weight.

The calcium saccharate composition of the present invention is also useful as a starch pregelatinizing agent and can also be used as a protein coagulant.

Next, the case where the calcium saccharate composition of the present invention is used for producing a calcium silicate compound will be described.

Calcium silicate compounds are produced by using clay minerals such as diatomaceous earth, clay, and bentonite as silicic acid raw materials, and natural silicate minerals such as silica powder and volcanic ash, or artificial silicate minerals such as incineration ash and blast furnace slag, and reacting them with quicklime or lime. It is a thing.

Conventionally, these calcium silicate compounds have been produced by kneading a mixture of a silicate raw material and quicklime or lime with water, and curing the mixture in an autoclave through a hydrothermal reaction. This is because in the conventional method, the reaction between silicic acid and lime is most favorable at around 150°C, and the reaction cannot be completed at temperatures below 100°C.

In the present invention, when quicklime or slaked lime reacts with sugars to produce calcium saccharate, its solubility in water becomes extremely high. Taking advantage of this fact, a calcium silicate compound can be easily obtained using a silicic acid raw material and a low temperature of 100°C or less. It was very successful.

In this reaction, sugars form quicklime or slaked lime and a supersaturated aqueous solution, a solid and liquid reaction of silicic acid and calcium saccharate occurs, and at the end of the reaction, sugars dissociate and react again to produce quicklime or lime and calcium saccharate. Sugars act as a kind of catalyst to produce calcium silicate (
It is based on principles.

Therefore, the amount of sugar added to this reaction has a large effect on the production of calcium silicate. That is, there is a difference in reactivity depending on the degree of lime supersaturation of the sugar, and this results in a quantitative difference that affects the reaction, so it is necessary to select a sugar with as high a degree of lime supersaturation as possible.

Sugars suitable for this purpose include glucose, caster sugar, and molasses, and highly refined sugars are not suitable.

In the present invention, the reaction equivalent of quicklime or slaked lime and various silicic acid raw materials depends on the purity of each, but is approximately ±100 parts by weight of diatoms for 65 parts by weight of quicklime for Bordeaux.

This reaction equivalent is approximately the theoretical amount, and even in the case of other raw materials, the objective can be achieved with the theoretical amount based on purity.

If necessary, quicklime may be partially replaced with slaked lime.

Furthermore, although quicklime is not particularly specified in the present invention, hard-burned quicklime is mainly used in the conventional method, whereas lightly-burned quicklime can be used in the present invention.

The method for synthesizing a calcium silicate compound using the calcium saccharate composition of the present invention includes a method in which saccharides are directly dissolved in kneading water, a method in which calcium saccharate is synthesized in advance and used as an aqueous solution, or a method in which calcium saccharate is synthesized in advance and used as an aqueous solution, or calcium saccharate in powder form is used. Any method is fine, such as using it as a.

Although these methods of adding calcium saccharate cause some differences in the initial reaction of calcium silicate, they do not affect the final product.

In the present invention, the amount of sugar or calcium saccharate added is 0.00 parts by weight per 100 parts by weight of lime in terms of sugar.
02 to 10 parts by weight, preferably 0.1 to 5 parts by weight.

In the present invention, cement, alumina, sodium silicate, slag, alkali metal salts, and chelating agents can be used as reaction aids.

The present invention does not negate the conventional method, but is a means for further rationalizing the production of calcium silicate by combining the present invention and the conventional method.

In the present invention, calcium saccharate is used as a reaction catalyst to promote the reaction in the synthesis of calcium silicate. Therefore, if the amount of sugar added is not within the above range, the cured product will have poor water resistance and will not have good physical properties. The nature of the hydration product of calcium silicate in the presence of sugars is that the initial hydrate is C
Due to the generation of a large amount of -5-H gel, C3H and tobermorite, which are not seen in conventional methods, were generated at room temperature.

Ca (OH) due to hydration of CaO with the addition of INs
The solubility of No. 2 in water increases and increases with the amount of sugar added, which is why the above reaction is promoted at room temperature.

Utilizing this reaction, it can be used in place of conventionally manufactured calcium silicate products as well as Portland cement, and can be installed on-site.

Moreover, Portland cement can be used to harden clays that are difficult to harden. It also has a wide range of uses due to its low cost.

For example, not only can we supply ALC and silica plates at low cost,
We can manufacture most of the concrete products for civil engineering and construction materials. In-situ decommissioning can also be used as a soil stabilizer.

For example, when a mixture of quicklime and slaked lime containing the calcium saccharate composition of the present invention is consolidated using the Kanto Rogo five construction site, a hardened product with early strength can be obtained.

This composition consists of a mixture of 70 parts by weight of quicklime and 30 parts by weight of slaked lime and Grape I! 120 parts by weight of 3% aqueous solution and 200 parts by weight of waste soil
Parts by weight were mixed and solidified. The setting time is 23 minutes,
The sample temporarily increases its strength at room temperature and reaches a compressive strength of 18 kg in one week.
/cm2. After 4 weeks, the compressive strength was 64 kg/cm2.

When the present invention is used as a grouting agent, the particle size of the raw material used,
It must satisfy conditions such as viscosity, thixotropy, permeability, gel time, gel strength, water resistance, and safety.

Grouting agents are used for a variety of purposes and require different performance, such as water-stop grout, backfill grout, and soil stability grout. Therefore, since the grouting agent of the present invention has a particle size of 5 microns or more, the scope of use is naturally restricted, but it is suitable for backfill grout and soil stabilizing grout that require a gel time of about 10 minutes.

For example, in a formulation of 100 parts by weight of bentonite, 60 parts by weight of quicklime, slaked lime mixture (including 20 parts by weight of calcium saccharate), and 200 parts by weight of water, the LW method uses 100 parts by weight of No. 3 sodium silicate, 100 parts by weight of water, and 100 parts by weight of Portland cement. The liquid properties are similar to those of 100 parts by weight of soil and water. However, the grouting agent of the present invention has superior permeability to standard sand. In order to accelerate the gel time, it is effective to add caustic soda, sodium silicate, etc. to the formulation of the grouting agent of the present invention to increase the reaction activity.

The calcium silicate compound obtained by the present invention is used in almost the same way as Portland cement, and the difference is that it generates heat during mixing. can be manufactured.

Next, the case where the calcium saccharate composition of the present invention is used as a cement admixture will be described.

When the calcium saccharate composition of the present invention is added in an amount of 2 to 10% by weight to Portland cement (hereinafter referred to as cement), the viscosity of the cement slurry increases and at the same time, the cement becomes rapidly set.

Sugars are known to retard the setting and reduce the strength of cement and corrode concrete. However, this is for use as dirt, and the calcium saccharate composition of the present invention, which is completely crushed by reacting sugar with calcium, is completely harmless to concrete. That is, even if a concrete specimen is immersed in a 20% by weight calcium saccharate aqueous solution for one month, the strength of the concrete specimen does not decrease at all.

Furthermore, by applying a 20% by weight calcium saccharate aqueous solution to a neutralized concrete specimen, it is effective in re-alkalizing it and increasing its strength.

Sugars used in cement admixtures include polysaccharides in addition to sucrose and starch sugar.

Preferably, a saccharide with high calcium solubility, which is inexpensive and does not affect cement strength, is required. 1 like this
1! Examples include glucose, sucrose, fructose, maltose, xylose, lactose, sorbose, true alcohol and invert sugars or sugar derivatives thereof.

To produce the cement admixtures of the invention, the OH groups of the sugars must be reacted with calcium until they are completely saturated. Therefore, it is necessary to use a slight excess of quicklime or add slaked lime to create a state where no unreacted substances occur. However, there must be no unreacted quicklime.

The reaction ratio of the sugars and quicklime or slaked lime is 20 to 40 parts by weight of lime per 100 parts by weight of sugars.

However, this varies depending on the type of sugar, and for sucrose it is 100
The amount of lime is 20 to 30 parts by weight.

Depending on the application, this cement admixture is provided as a powder or an aqueous solution. Other cement admixtures may also be used.

This cement admixture is almost the same as calcium chloride.
It exhibits viscosity and has higher strength than calcium nitrate, calcium formate, calcium thiosulfite, etc.

Calcium chloride is 1.0 to 100 parts by weight of cement.
It was used in an amount of 3.0 parts by weight, but because of its freezing point lowering effect, it was used in combination with bicondensation to prevent concrete from freezing in field work and to prevent curing and short circuits in secondary concrete product factories. However, its use was discontinued due to corrosion of reinforcing steel, and a new quick-setting agent was required to replace it. The calcium saccharate composition of the present invention has the same viscosity and freezing point depressing effect as calcium chloride. Conventionally, when calcium chloride is added to cement, it generates a slight amount of heat, but this heat generation greatly affects the setting of cement. It is effective for The calcium saccharate composition of the present invention also exhibits heat generation similar to or higher than that of calcium chloride. Cement) When the water ratio was 0.5 on a 200g scale, a temperature increase of 5.3°C was observed.

Also, when synthesizing Cl2A7 and C1l87CF2,
Conventionally, the main raw materials were alumina and calcium carbonate, which were melted in an electric furnace, crushed, hydrated, remelted, and repulverized. The reason for this is that the reactivity during melting is low. Therefore, in the present invention, aluminum dross, aluminum hydroxide, and alumina are used as alumina sources, and slaked lime or quicklime is used as a calcium source to reduce sugars to 1.
When kneaded and melted with ~50% by weight aqueous solution, Cl
2A7 and C11A7CF2 were successfully synthesized.

This is because when the powder used as an alumina source and the powder used as a calcium source are simply used with water, they tend to react on the surface of these particles and form an unreacted calcium source, whereas when sugars are present, they are in a solution state. This is because it is difficult to react and form lumps. Therefore, the reaction efficiency increased, and the free lime amount was 0.7% at -degree melting.

Furthermore, even when calcined at 800°C without the melting method, 0.9% of free lime remained.

Calcium aluminate synthesized in this way is mixed with a trace amount of hydroxocarboxylic acid salt to form a compound with a weight of 5 to 1% of the cement weight.
When added at 0% by weight, it becomes a high-performance cement quick-setting agent.

The calcium saccharate composition of the present invention as described above is
It is obtained by using quicklime, slaked lime, or dolomite plaster as lime and reacting it with various sugars.

Calcium source 7/colored composition of the present invention can be produced by varying the type of saccharide and the amount of calcium saccharate in quicklime and slaked lime depending on the purpose. The method for producing pure calcium saccharate is to react sugars with lime such as quicklime, slaked lime, or dolomite plaster as an aqueous solution, and recrystallize from this reaction solution to obtain a pure product. In this method, the reaction solution is generally treated, and the filtrate is concentrated and cooled to precipitate calcium sanocalate crystals. However, in the case of highly deliquescent calcium saccharate, the water in the concentrate is replaced with a water-soluble solvent to precipitate calcium saccharate crystals. The crystals are filtered, vacuum dried, and packaged to prevent exposure to air. The calcium saccharate crystals obtained in this way are white, plate-like or needle-like, and depending on the type of sugar, some calcium saccharates have a low melting point, and some are easy to liquefy at room temperature and exist as crystals only in concentrated liquids. .

Furthermore, the higher the purity of the sugar, the easier it is to obtain calcium saccharate crystals, and the lower the purity, the worse the crystallinity.

The production reaction of calcium saccharate has been known for some time, but in most cases it is handled as a solution rather than taken out as a single product, and its physical properties are not clear. Therefore, it is believed that calcium saccharates of various saccharides can be produced by the above-mentioned production method, and that new uses for calcium saccharates will be found.

In the method for producing calcium saccharate of the present invention, the reaction equivalent of uCaO or Ca2 to sugars is proportional to the monosaccharide molecule that is the composition of sugars, regardless of the type of sugars.
It is the weight ratio of monosaccharide 4 to al.

Therefore, if the composition amount does not correspond to this weight ratio, it must be treated as a composition.

Furthermore, not only calcium sasocalate but also double salt sasoxalate compounds such as magnesium and barium oxides and hydroxides or dolomite can be produced by the above method.

[Examples] Hereinafter, the present invention will be explained in more detail with reference to Examples.
The present invention is not limited to these examples.
