Description

Sweet composition containing dietary fiber and method of preparing the same {Sugar composition including dietary fiber and method of preparing for the same}

The present invention relates to a method for producing a sweet composition containing dietary fiber, and to a method and composition for producing sugar containing an excessive amount of dietary fiber by binding together crystalline sweet particles with a high dietary fiber content. At this time, crystalline sugar powder and amorphous dietary fiber powder can be uniformly mixed by coating and vacuum drying using alcohol, and at the same time, fine powder can be reduced and product yield can be improved.

Since sugar is easily digested and absorbed in the body and rapidly increases blood sugar levels, there is a perception that foods containing excessive sugar are harmful to health by causing diabetes and obesity.

In order to reduce sugar intake, the development of alternative sweeteners has been underway to reduce sugar intake and achieve health functional effects at the same time by replacing some of the sugar with dietary fiber.

Dietary fiber, for example, indigestible maltodextrin, has functional effects such as facilitating bowel movement, suppressing the rise in blood sugar after a meal, and improving neutral lipids in the blood, so it is registered as a health functional food ingredient and is highly utilized in products with a health-oriented concept. However, indigestible maltodextrin has the disadvantage of poor fluidity, causing fine particles to fly out when consumed alone, and is not easy to handle.

Accordingly, there is a need to provide a sweet composition that mixes sweeteners such as sugar with dietary fiber to have uniform mixing and sweetness, prevents re-separation, and has a high dietary fiber content. Accordingly, in order to increase the mixing uniformity of sweeteners, such as sugar, and dietary fiber, such as indigestible maltodextrin, a binder or binder solution capable of binding the two components is required, but some of the mixed raw material components are sprayed into a spray solution. The conventional technology used has the disadvantage of making it difficult to increase the dietary fiber content in the sweet composition by more than a certain amount because it fails to evenly disperse dietary fiber and increases agglomeration of dietary fiber powder, thereby reducing production yield.

Therefore, the present invention uses alcohol, which is a substance other than the mixed raw material component, as a coating liquid and applies a reduced-pressure drying method to reduce the agglomeration phenomenon of dietary fiber and sufficiently bind crystalline sugar and amorphous dietary fiber to increase the dietary fiber content to a certain amount. The goal is to obtain a sugar composition high in dietary fiber that can increase the sugar content.

In addition, the present invention seeks to provide a dietary fiber-containing sugar composition containing a high content of dietary fiber and a method for producing the same.

In addition, since it is difficult to bind a large amount of dietary fiber with a crystalline sweetener, a method for producing a sweet composition high in dietary fiber using alcohol coating and reduced pressure drying is provided to solve this problem.

The present invention is based on the distribution of sugar and functional powder materials in a uniform composition ratio and varies the coating and drying method, thereby reducing the fine powder, uniform distribution, and reducing the amount of dietary fiber loss due to agglomeration during the manufacturing process, thereby improving industrial production efficiency. Provides a method to increase . At the same time, it is possible to provide a sweet composition containing a high content of dietary fiber.

An example of the present invention is that it is not easy to create a uniform powder form such as binding, coating, or granulation because the particle shapes of the crystalline sweetener and the amorphous powdered sweetener or functional material are different. Therefore, a method for manufacturing a saccharide composition containing a high content of dietary fiber and sugar is provided by increasing the mixing ratio of sweetener and dietary fiber. The sweet composition is prepared by spraying an aqueous ethanol solution onto a mixture of crystalline sweetener and amorphous dietary fiber powder while stirring in a reaction tank, and applying a vacuum pressure of 15,000 to 150,000 Pa in the vacuum device, preferably 50,000 to 100,000 Pa, more preferably 60,000 Pa. It is ~96,000 Pa, and the temperature in the vacuum device is 30 to 90°C, preferably 50 to 70°C. It can be manufactured by drying under reduced pressure. By the above manufacturing method, sugar and sweetener material or dietary fiber are distributed in a uniform composition, and a reduced pressure drying method is adopted to reduce fine powder loss and increase industrial production efficiency.

Specifically, the method for producing the dietary fiber-containing sweet composition is

(1) Solid phase mixing of crystalline sweetener and dietary fiber

(2) a liquid coating step of spraying a coating solution of alcohol or an aqueous solution thereof, which is a third substance other than the raw material, onto the mixture;

(3) Applying a vacuum to the mixer containing the liquid coated mixture to evaporate moisture at low pressure and drying it.

Hereinafter, the present invention will be described in more detail.

The powdery sweet composition according to the present invention includes a crystalline sweetener and amorphous dietary fiber powder, and the dietary fiber powder is included in the sweet composition in a form coated or bound to the surface of the crystalline sweetener powder.

The sweet composition according to the present invention may have a moisture content of 0.5% by weight or less, a recovery rate of the prepared sweet composition, that is, mixed sugar, of 90% or more, and a fine powder amount of 10% or less. The uniformity of the granular sweet composition may be such that the deviation of the average weight% of the content of crystalline sweet particles and amorphous dietary fiber is ±1.5% by weight or less, preferably ±1.0% by weight or less.

The powdered sweet composition contains, for example, 1% by weight or more of dietary fiber based on 100% by weight of the sweet composition containing crystalline sweetener powder and amorphous dietary fiber, for example, the crystalline sweetener is 40 to 99% by weight. Weight percent, the dietary fiber material may be 1 to 60 weight%, preferably the crystalline sweetener may be 40 to 98 weight%, and the dietary fiber material may be 2 to 60 weight%. If the mixing ratio of dietary fiber material is high, it causes fine powder and an increase in weight distance, and has the disadvantage of making it difficult to achieve sweetness similar to crystalline sweeteners. If the mixing ratio is low, it has the disadvantage of reducing calories and reducing functional effects.

Based on 100% by weight of the sweet composition according to the present invention, the dietary fiber content included is 1-60% by weight, preferably 2-60% by weight, 2-50% by weight, 2-40% by weight, 2-30% by weight. , 4 to 60% by weight, 4 to 50% by weight, 4 to 40% by weight, 4-30% by weight, 5 to 60% by weight, 5 to 50% by weight, 5 to 40% by weight, 5-30% by weight, 6 to 60% by weight, 6 to 50% by weight, 6 to 40% by weight, or 6-30% by weight.

The powdery sweet composition according to the present invention preferably has a sugar composition deviation of ±1.5% or less between components, for example, ±1.0% or less. In addition, the sweet composition has a content of particles that did not pass through the 16-mesh vibrating screen (distance-free content) of 10% by weight or less, based on 100% by weight of the total sweet composition, and a content of particles that passed through the 80-mesh vibrating screen (fine content). It may be 10.0% by weight or less, and preferably, the powder content may be 6% by weight or less, and the fine powder content may be 8.0% by weight or less.

The crystalline sweetener powder included in the powdery sweet composition according to the present invention may be one or more types selected from the group consisting of sugar, fructose, and allulose. The sugar may be white sugar, brown sugar, etc. depending on the degree of purification, and may be refined sugar, fine-grained sugar, fine-grained sugar, or powdered sugar depending on the average particle size.

The particle size of the crystalline sweetener powder is 50 to 98% by weight, and particles having a particle size of 20mesh or less and 80mesh or more (a size that passes through a 20mesh vibrating screen but cannot pass through an 80mesh vibrating screen) are 50 to 98% by weight based on 100% by weight of the sweetener powder. Particles with a size (size that passes through 80mesh) are 2 to 2. It may be 50% by weight. Preferably, sugar, allulose, and crystalline fructose can be manufactured by selecting an appropriate particle size for each sample in consideration of the range set above.

For example, in the sugar particle size distribution, based on 100% by weight of the sugar composition, 50 to 98% by weight of particles have a particle size of 20mesh or more and 80mesh or more (a size that passes through a 20mesh vibrating sieve but does not pass through an 80mesh vibrating sieve) and 80mesh. 2 to 50% by weight of particles having the following size (size that passes through 80mesh), preferably 80 to 95% by weight of particles having a size of 20mesh or less and 80mesh or more, and 5% of particles having a size of 80mesh or less. It may be from 20% by weight.

The amorphous dietary fiber contained in the powdery sweet composition according to the present invention may be one or more selected from the group consisting of indigestible maltodextrin, inulin, and polydextrose. The amorphous or non-crystalline state is intended to include powders, granules, etc. in the form of an amorphous solid that has not formed crystals.

As used herein, the term dietary fiber refers to a component known as fiber or cellulose, which is abundant in vegetables, fruits, and seaweed among foods, and refers to high molecular weight carbohydrates that are not digested by human digestive enzymes and are excreted out of the body. It may contain cellulose, hemicellulose, or lignin, or soluble dietary fiber, such as pectin from fruits, vegetable gums, or polysaccharides from seaweed, and polydextrose and low molecular weight alginic acid produced by biotechnological methods. , or indigestible maltodextrin. Accordingly, the dietary fiber according to the present invention may be one or more selected from the group consisting of cellulose, hemicellulose, lignin, pectin, vegetable gums, polysaccharides of seaweed, inulin, polydextrose, alginic acid, and indigestible maltodextrin.

The indigestible maltodextrin is rich in dietary fiber and has effects such as smoothing bowel movements, suppressing the rise in blood sugar after a meal, and improving neutral fat content in the blood. It is very useful as a health functional food ingredient in health-oriented concept products. However, due to the nature of the product in a light powder form, it has the disadvantage of not being easy to handle due to severe dust scattering when consumed or used alone.

The particle size distribution of the dietary fiber material applicable to the present invention is 3 to 40% by weight of particles having a size of 20mesh or less and 80mesh or more, and 60 to 97% by weight of particles having a size of 80mesh or less, preferably 20mesh or less and 80mesh or more. Particles with a size of 80 to 97% by weight may be 3 to 20% by weight, and particles with a size of 80mesh or less may be 80 to 97% by weight. If the particle sizes of the two components being mixed are similar, uniformity can be increased after mixing, but if the particle size difference is large, there is a problem of poor uniformity after mixing.

In order for two components of different particle shapes to be uniformly mixed and maintain uniformity without separation, binding using a coating liquid that can bind the two components is necessary rather than a simple mixing method. It is more appropriate to use alcohol as a coating solution than to use sugar, which is part of the mixed raw material component, as it reduces the loss of amorphous dietary fiber powder material. The water component of the coating liquid plays a role in binding the mixed composition, and the alcohol has the effect of preventing the agglomeration of the powdered dietary fiber material and dispersing it evenly, making it more uniform than sugar coating.

Accordingly, the coating solution applied in the present invention may be an ethanol aqueous solution containing 30 to 90 wt/wt% of ethanol. The coating liquid is 0.1 to 20 parts by weight, 0.5 to 20 parts by weight, 1 to 20 parts by weight, 0.1 to 15 parts by weight, and 0.5 to 15 parts by weight, based on 100 parts by weight of the total weight of the crystalline sweetener and amorphous dietary fiber powder. , 1 to 15 parts by weight, 0.1 to 10 parts by weight, 0.5 to 10 parts by weight, 1 to 10 parts by weight, 0.1 to 8 parts by weight, 0.5 to 8 parts by weight, 1 to 8 parts by weight, 0.1 to 6 parts by weight, 0.5 It may be treated at 1 to 6 parts by weight, or 1 to 6 parts by weight.

Therefore, if the content of fermented alcohol in the coating liquid is high, the binding force decreases and uniformity is low. Conversely, if the content of fermented alcohol is low, the binding force becomes stronger and the mixing uniformity improves, but it can increase the agglomeration phenomenon of the dietary fiber powder material, so the appropriate fermented alcohol mixing ratio is not required. need. In addition, a similar effect was confirmed in the mixture of fructose or allulose crystals and polydextrose or inulin, with a composition deviation of less than 1% as in the case of sugar and indigestible maltodextrin dry powder.

The coating liquid may be 0.5 to 20 parts by weight, more preferably 1 to 6 parts by weight, based on 100 parts by weight of the total content of crystalline sweetener and amorphous dietary fiber used in mixing. The coating liquid can be used by spraying on crystalline sweetener and amorphous dietary fiber or a solid mixture thereof. If the spray amount of the coating liquid is large, the drying time may be prolonged, and if the spray amount is too small, the uniformity of the product may decrease.

The coating solution may be an ethanol aqueous solution, for example, an ethanol aqueous solution containing 30 to 90 w/w%, 40 to 90 w/w%, preferably 55 to 75 w/w%.

Compared to the conventional coating technology with a sugar solution, which is one of the raw material ingredients, it was confirmed that the fine powder content in the product was further reduced in the alcohol coating method as in the present invention. If the fermentation alcohol content of the coating liquid is low, the reduction in fines is large, but if it is too high, the content of fines in the product increases, affecting the process yield. Therefore, it is advisable to set the fermented alcohol content of the coating liquid considering the fine powder and coarse content in the produced product.

Vacuum drying of the sweet composition according to the present invention is performed at a vacuum pressure of 15,000 to 150,000 Pa, preferably 50,000 to 100,000 Pa, more preferably 60,000 to 96,000 Pa, and a temperature in the vacuum device of 30 to 90°C. Typically, it may be in the range of 50 to 70 degrees Celsius. If the vacuum pressure is too low, moisture evaporation does not occur smoothly due to the vacuum, and if it is too high, work efficiency may decrease and utility costs may increase inefficiently. In addition, if the temperature is too low, even if the vacuum pressure is appropriate, the drying time may become longer and the friction between particles may intensify, which may further increase the amount of fine powder produced. If the temperature is too high, drying will occur quickly and the temperature suitable for discharge ( Since it takes a long time to cool down to 40℃, this also reduces work efficiency. If the mixture is discharged when the internal temperature is too high, condensation may occur due to the difference with the external temperature, which may cause solidification problems.

According to the present invention, when manufactured by vacuum drying in the process of mixing crystalline sweet particles and amorphous dietary fiber particles in solid phase and mixing ethanol aqueous solution by spraying as a coating solution or spray solution, each component constituting the composition is uniform. Not only is it distributed in one composition, but compared to drying methods such as hot air drying and fluidized bed drying, the amount of fine powder produced is reduced and the amount of product loss can be reduced, thereby improving productivity and increasing work efficiency. In addition, by manufacturing using an ethanol aqueous solution coating solution, there is an advantage of increasing the dietary fiber content in the powdered sweet composition.

Below, the method for producing the granular sweet composition according to the present invention will be described in detail step by step.

The mixing, coating and drying processes for preparing the sweet composition can be performed while stirring in a reaction tank. The reaction tank may rotate at a linear speed of 1 to 15 m/s. The stirring may be performed by the movement of the reaction tank itself, the movement of the stirring blade, or the temperature of the stirring tank and the stirring blade, and the movement may be performed in various ways including rotation, up and down movement, and vibration.

mixing step

This is a step of uniformly mixing dietary fiber particles and crystalline sweet particles, and is a step of mixing crystalline sweet particles and dietary fiber particles in a solid phase.

The crystalline sweet particles used in the present invention have a particle size of 20 mesh or less (-) to 80 mesh or more (+) based on 100% by weight of the crystalline sweet particles (a size that passes through a 20 mesh vibrating screen but does not pass through an 80 mesh vibrating screen). 50 to 98% by weight of particles and 2 to 50% by weight of particles having a size of 80mesh or less (+) (size that passes 80mesh), preferably 20mesh or less (-) to 80mesh or more (+). The particles having a size of 80 to 95% by weight may be 80 to 95% by weight, and the particles having a size of 80 mesh or less may be 5 to 20% by weight. If the particle size of the mixed sweetener increases, uniformity decreases after mixing, and if the particle size decreases, agglomeration occurs due to fine powder and uniformity decreases. For reference, a (+) sign indicates that it did not pass through a sieve with the corresponding mesh, and a (-) sign indicates that it passed through a sieve with the corresponding mesh.

Additionally, the step of preparing the mixture may be performed while stirring, and the reaction tank may rotate at a linear speed of 1 to 15 m/s. The stirring may be performed by the movement of the reaction tank itself, the movement of the stirring blade, or the movement of the stirring tank and the stirring blade, and the movement may be performed in various ways including rotation, up and down movement, and vibration.

The step of preparing the mixture does not require a specific temperature, pressure or time range, but only needs to satisfy the conditions that allow different types of powders to be mixed homogeneously. Crystalline sweet particles or amorphous dietary fiber particles can be mixed at preferably 35 to 80°C, preferably 45 to 70°C for 0.1 to 60 minutes.

Spray mixing of coating liquid

After the solid phase mixing step, there is a coating or binding step in which an aqueous ethanol solution is sprayed onto the mixture of the solid phase mixing step.

The ethanol aqueous solution for spraying is 0.1 to 20 parts by weight, 0.5 to 20 parts by weight, 1 to 20 parts by weight, and 0.1 to 15 parts by weight, based on a total of 100 parts by weight of crystalline sweet particles and amorphous dietary fiber powder used in preparing the mixture. Parts by weight, 0.5 to 15 parts by weight, 1 to 15 parts by weight, 0.1 to 10 parts by weight, 0.5 to 10 parts by weight, 1 to 10 parts by weight, 0.1 to 8 parts by weight, 0.5 to 8 parts by weight, 1 to 8 parts by weight , it may contain 0.1 to 6 parts by weight, 0.5 to 6 parts by weight, or 1 to 6 parts by weight.

If the amount of the spray liquid is excessive, the yield decreases, and if the amount of the spray liquid is too small, the degree of mixing decreases, so it can be used within the above range. The ethanol aqueous solution may be, for example, an ethanol aqueous solution containing 30 to 90 w/w%, 40 to 90 w/w%, and preferably 55 to 75 w/w%. In the step of forming the coating layer, the temperature inside the reaction tank can be set to be the same or similar to the temperature in the reduced pressure drying step. Specifically, the internal temperature of the process may be in the range of 30 to 90°C, preferably 50 to 70°C.

Reduced pressure drying step

It includes drying the sweet material powder on which the coating layer is formed. This may be a step of drying the mixture by applying a vacuum to evaporate moisture at a low external temperature.

This is a step of drying by applying a vacuum to the reaction tank containing the mixture from the liquid coating mixing step to evaporate moisture at a low external temperature. Specifically, it may be a step of drying under reduced pressure under conditions of 15,000 to 150,000 Pa, preferably 50,000 to 100,000 Pa, more preferably 60,000 to 96,000 Pa, and a temperature of 30 to 90°C, preferably 50 to 70°C.

The vacuum drying can be done with stirring until the moisture content is 0.5% or less. Compared to the conventional fluid bed drying method or hot air drying method, the amount of fine powder loss is significantly reduced, the yield of mixed sugar is increased, process efficiency is increased, and process energy is reduced. In addition, the fluidized bed drying or hot air drying method is sensitive to the homogeneity and efficiency of mixed sugar production due to differences in particle size of the heterogeneous sweet materials being relatively mixed, but the present invention provides granular sweet composition or It has the advantage of being able to produce mixed sugars uniformly and with high yield.

The vacuum pressure applied to the reaction tank is 15,000 to 150,000 Pa, preferably 50,000 to 100,000 Pa, more preferably 60,000 to 96,000 Pa, and the temperature in the vacuum device is 30 to 90°C, preferably 50 to 70°C. It may be a range. If the vacuum pressure is too low, moisture evaporation does not occur smoothly due to the vacuum, and if it is too high, work efficiency may decrease and utility costs may increase inefficiently. In addition, if the temperature is too low, even if the vacuum pressure is appropriate, the drying time may become longer and friction between particles may intensify, which may further increase the amount of fine powder produced. If the temperature is too high, drying will occur quickly and the temperature suitable for discharge ( Since it takes a long time to cool down to 40℃, this also reduces work efficiency. If the mixture is discharged when the internal temperature is too high, condensation may occur due to the difference with the external temperature, which may cause solidification problems.

In one example of the present invention, food compositions and beverage compositions using the sweetening composition can be manufactured, and preferably, it can be added to powdered food and beverage products and compositions for manufacturing these products. The food and beverage products and the beverage composition may be applied to powdered tea products or coffee products.

The present invention relates to a method for producing a sweet composition containing dietary fiber, and to a method and composition for producing sugar containing an excessive amount of dietary fiber by binding together crystalline sweet particles with a high dietary fiber content. At this time, crystalline sugar powder and amorphous dietary fiber powder can be uniformly mixed by coating and vacuum drying using alcohol, and at the same time, fine powder can be reduced and product yield can be improved.

The present invention will be explained in more detail with reference to the following examples, but it is not intended that the scope of protection of the present invention be limited to the scope of the following exemplary examples.

It was determined that the composition was uniformly mixed so that the deviation in sugar composition between components was 1.0% or less. According to the results of the sugar composition deviation, it was confirmed that the uniformity of the sugar coating and the fermented alcohol coating were superior to those of simple mixing.

In order for two components of different particle shapes to be uniformly mixed and maintain uniformity without separation, a coating step that can bind the two components is required rather than a simple mixing method. It is more suitable to use fermented alcohol as a coating solution than to use sugar, which is part of the mixing component, as it reduces the loss of amorphous dietary fiber powder material. The water component of the coating liquid plays a role in binding the mixed composition, and at this time, the alcohol has the effect of preventing the agglomeration of the powdered dietary fiber material and dispersing it evenly, making it more uniform than sugar coating. Therefore, if the content of fermented alcohol in the coating liquid is high, the binding force decreases and uniformity is low. Conversely, if the content of fermented alcohol is low, the binding force becomes stronger and the mixing uniformity improves, but it can increase the agglomeration phenomenon of the dietary fiber powder material, so the appropriate fermented alcohol mixing ratio is not required. need. In addition, a similar effect was confirmed in the mixture of fructose, allulose crystals, polydextrose, and inulin, with a composition deviation of less than 1%, as with sugar and indigestible maltodextrin dry powder.

Test Example 2. Comparison of particle size distribution of sugar mixture compositions containing dietary fiber

In order to confirm the particle size distribution of the mixed composition prepared according to Comparative Examples 1 and 2 and Examples 1 to 9, 100 g of each sample was collected by preparing vibrating mesh sizes (20, 40, 60, 80, 100 mesh). After applying vibration to the vibrating body for 5 minutes, the amount of sample (sample that did not pass) remaining in the vibrating body was expressed as weight percent based on 100% by weight of the total product. At this time, the amount of the sample (passed sample) that passed through the 80-mesh vibrating screen defines the fines content. Accordingly, in Table 2 below, the fines content is the same as the fines content of the sample whose total content of 100 and PAN passed the 80 mesh. If the fine powder content in the product was 10% or less, it was judged to be at an appropriate level as a product. The higher the fine powder content of the product, the more dust is generated during packaging work, which can cause sealing problems. Therefore, the smaller the fine powder is, the easier it is to work. In addition, the entire manufactured dry powder was passed through a 16mesh vibrating screen, and the amount of sample (sample that did not pass) remaining in the 16mesh vibrating screen was divided by the total weight of the manufactured dry powder, and the content was expressed as weight%, which was expressed as the zero-distance content. If the amount of undistance is large, the amount of work loss increases, so minimizing it will help improve yield. In Table 4 below, the mark "20 up" indicates the weight percent of the sample that did not pass the 20 mesh vibrating screen.

As shown in Table 4, Comparative Example 1 had a high fine powder content in the product, and it was confirmed that the fine powder content was reduced in Comparative Example 2 and Examples 1 to 3 where the coating step and reduced pressure drying were performed. In addition, it was confirmed that the fine powder content was reduced more with the fermented alcohol coating method than with the sugar coating method. If the fermentation alcohol content of the coating liquid is low, the reduction in fines is large, but if it is too high, the content of fines in the product increases, affecting the process yield. Therefore, it is necessary to set the alcohol content of the coating liquid taking into account the fine and coarse content. Since the dietary fiber material is a powder in the form of fine powder, the higher the content, the higher the fine powder content may be. Crystalline fructose and allulose crystals have smaller particles than sugar, which may be a factor in slightly increasing the fine content of the final product.

In the mixture of fructose, allulose crystals, polydextrose, and inulin, it was confirmed that the fine powder content was less than 10% and the degree of no distance generation was similar to that of sugar and indigestible maltodextrin dry powder. Accordingly, the sweet composition according to the present invention is preferably a powder composition in which the residual sample (sample that did not pass, 16 above) is 10% by weight or less when treated with a 16 mesh vibrating screen, and the fine powder content that passed through the 80 mesh vibrating screen is 8.0 weight% or less. .
