[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, the "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0028] The embodiments of the present application provide a method for preparing a tableted food, such as Figure 1 As shown, the method includes:

[0029] Step 101, preparing a raw material mixture, wherein the raw material mixture has a plurality of particle size ranges; by preparing the raw material mixture into different particle size ranges, the produced compressed food has a richer chewing level;

[0030] Step 102, mixing a raw material mixture having a plurality of particle size ranges according to a first weight ratio; by mixing the raw material mixture having different particle size ranges according to the first weight ratio, it can be ensured that the produced compressed food is neither too hard nor quickly disintegrated in the mouth, and can maintain a moderate hardness and crispness when chewing;

[0031] Step 103, tabletting the mixed raw material mixture of various particle size ranges using a tablet press to obtain the tablet food. Here, the tablet food is, for example, milk tablets, nutritional tablets or health products, etc., which have high requirements on taste.

[0032] In the above step 103, during tableting, the tableting pressure of the tablet press is selected to be a medium pressure, such as 5-15 MPa, so that the tablet (tablet food) can have both appropriate hardness and good disintegration during chewing.

[0033] In the preparation method of the tablet food of the embodiment of the present application, first, a raw material mixture is prepared, wherein the raw material mixture has a plurality of particle size ranges; second, the raw material mixture with a plurality of particle size ranges is mixed according to a first weight ratio; finally, the mixed raw material mixture with a plurality of particle size ranges is tableted by a tablet press to obtain the tablet food. In this way, by mixing and pressing the tablet food from the raw material mixture with different particle size ranges according to the first weight ratio, the texture and taste of the tablet food can be improved, and the chewing experience of the tablet food can be enhanced, so that the tablet food has a perfect combination of softness, brittleness and layering when chewing, which solves the problem of poor taste existing in the prior art.

[0034] As a specific implementation, the raw material mixture with multiple particle size ranges includes a raw material mixture of a first particle size range and a raw material mixture of a second particle size range, wherein the first particle size range is 10 to 50 microns, the second particle size range is 100 to 200 microns, and the first weight ratio between the raw material mixture of the first particle size range and the raw material mixture of the second particle size range is: 70% to 80%: 20% to 30%. That is, the weight of the raw material mixture of 10 to 50 microns accounts for 70% to 80% of the total weight of the tablet food, and the weight of the raw material mixture of 100 to 200 microns accounts for 20% to 30% of the total weight of the tablet food.

[0035] In the above specific implementation, the raw material mixture (fine particles) in the first particle size range is mainly used to fill the overall structure of the tablet food to improve the tablet density and taste uniformity, and the raw material mixture (medium particles) in the second particle size range is mainly used to increase the layered texture and crispness of the taste, so that the tablet food has a richer bite experience when chewing. By setting the first weight ratio between the raw material mixture in the first particle size range and the raw material mixture in the second particle size range to: 70% to 80%: 20% to 30%, the prepared tablet food can have the best chewing feeling.

[0036] As an optional implementation, step 101, preparing a raw material mixture, includes:

[0037] (1) Obtaining a plurality of raw materials for the tableted food, wherein a ratio between the various raw materials is a second weight ratio.

[0038] As a specific implementation method, the multiple raw materials in the above steps may include milk powder, sugars and fibers; wherein the second weight ratio between the milk powder, the sugars and the fibers is: 45% to 60%: 10% to 25%: 5% to 25%. That is, the milk powder accounts for 45% to 60% of the total weight of the compressed food, so that the milk powder can provide milk flavor and basic taste; the sugars account for 10% to 25% of the total weight of the compressed food, so that the sweetness and crispness of the compressed food can be enhanced and the crispness in the taste can be optimized; the fibers account for 5% to 25% of the total weight of the compressed food, so that the chewing level of the compressed food can be improved, and additional health benefits can be provided, and the elasticity and toughness of the texture can be increased.

[0039] As a more specific implementation, the sugar includes at least one of lactose, sugar alcohol, glucose, solid corn syrup, maltodextrin, maltose and fructose, wherein the sugar alcohol includes, for example, at least one of erythritol, maltitol, sorbitol, xylitol and isomalt. In this way, the adaptability of the tableted food to different market demands can be improved.

[0040] As another more specific implementation, the fiber includes at least one of dietary fiber, oligofructose, oligogalactose, inulin, resistant dextrin, oligomaltosaccharide, soluble fiber and microcrystalline cellulose. In this way, the health function of the tablet food can be further enhanced to meet different market demands.

[0041] As another specific implementation, on the basis that the raw materials include milk powder, sugars and fibers, the raw materials may further include at least one of minerals, vitamins and probiotics to enhance the nutritional value of the tableted food.

[0042] (2) The plurality of raw materials are mixed and granulated to obtain a raw material mixture having a plurality of particle size ranges.

[0043] As a specific implementation method, the above step (2), mixing and granulating the multiple raw materials to obtain a raw material mixture with multiple particle size ranges, includes:

[0044] The raw materials in the second weight proportion are uniformly mixed.

[0045] The spray drying process is used to refine the raw materials after uniform mixing; wherein, the moisture content (weight content) of the raw materials after refinement is between 3% and 5%; in this step, during the process of refinement of the raw materials after uniform mixing by the spray drying process, the working parameters of the spray drying tower are adjusted to ensure that the moisture content of the raw materials after refinement is between 3% and 5%, so that the subsequently prepared compressed food can maintain a good taste and structural stability, and prevent the compressed food from being too dry or too soft.

[0046] The refined raw materials are granulated by agglomeration process to obtain a raw material mixture with different particle size ranges. Specifically, this step is to separate the refined raw material mixture into two particle sizes (fine particle size and medium particle size) by agglomeration process.

[0047] As an optional implementation, before the plurality of raw materials are mixed and granulated to obtain the raw material mixture with the plurality of particle size ranges, the method further comprises:

[0048] The various raw materials are crushed and sieved respectively to obtain raw materials with uniform particle size. In this step, a crusher is used to crush various raw materials (for example, crushed into fine powder of 60-80 mesh), and the crushed raw materials are sieved so that the particle sizes of various raw materials after processing are close, that is, the particles are uniform, thereby improving the uniformity of raw material mixing. The problem of rough texture and inconsistent taste of existing tablet foods is solved.

[0049] In the above implementation, various raw materials are crushed and screened separately, and the mixed raw materials are refined and granulated, so that the particles of the raw materials are homogenized to ensure the consistency of texture and the layered taste of the prepared compressed food.

[0050] Below, taking the compressed food as milk tablets, the raw materials of which are milk powder, sugars and dietary fiber as an example, the implementation process of the method for preparing the compressed food of the embodiment of the present application is explained.

[0051] (1) Weigh the raw materials: milk powder: 45%-60%, sugar: 10%-25%, dietary fiber: 5%-25%;

[0052] (2) Crushing and sieving raw materials: All powdered raw materials are processed by a crusher to make the particles uniform, ensuring that the particle sizes of milk powder and sugar particles are close and improving mixing uniformity;

[0053] (3) Spray drying: the crushed raw materials are uniformly mixed, and the mixed raw material particles are finely processed using a spray drying tower with set working parameters to ensure that the moisture content is between 3% and 5%, so that the prepared milk tablets maintain a good taste and structural stability, and are not too dry or too hard; then, through the agglomeration process, the particle size of the raw material mixture is divided into two particle sizes (fine particle size and medium particle size), among which the particle size range of the fine particle size is 10 to 50 microns, accounting for 70% to 80%, and the particle size range of the medium particle size is 100 to 200 microns, accounting for 20% to 30%;

[0054] (4) Tabletting: The uniformly mixed raw material mixture of fine particles and medium particles is fed into a tablet press for tabletting to prepare milk tablets. The tablet press uses a medium pressure (5-15 MPa) so that the milk tablets have both appropriate hardness and good disintegration during chewing.

[0055] The present application is further described below through some specific embodiments.

[0056] Example 1: Design of composite powder particles of milk powder and sugar

[0057] Material composition:

[0058] Milk powder (55%): provides milk flavor and basic taste.

[0059] Lactose (32%): acts as a sweetener to enhance the sweetness and crunchiness of the tablets.

[0060] Soluble dietary fiber (8%): ​​used to enhance the tablet's structural strength and chewing texture.

[0061] Microcrystalline cellulose (5%): Improves tablet compression and disintegration properties.

[0062] Process steps:

[0063] Crushing and sieving: All raw materials are crushed to ensure uniform particle size.

[0064] Spray drying: The crushed materials are mixed, homogenized, concentrated and spray-dried, and through the agglomeration process, the medium-sized particles account for 20-30% and the fine particles account for 70-80%.

[0065] Evenly mix: Mix the above ingredients according to the proportions to ensure that the ingredients are evenly distributed.

[0066] Tableting process: Tableting was performed at a pressure of 8 MPa and the tableting temperature was controlled at 35°C.

[0067] Effect evaluation: The milk tablets after tableting have good crispness and softness, uniform taste, and no granular feeling when chewing. The moisture content after tableting is 4%, and the milk tablets do not clump during storage.

[0068] Example 2: Effect of increasing dietary fiber content in composite powder

[0069] Material composition:

[0070] Milk powder (60%);

[0071] Erythritol (20%);

[0072] Soluble dietary fiber (15%): Increase the proportion of dietary fiber to improve the health function of milk tablets;

[0073] Microcrystalline cellulose (5%).

[0074] Process steps:

[0075] The same process flow as Example 1.

[0076] Effect evaluation: The increase of dietary fiber makes the chewing feeling of milk tablets richer, and the tablets have a stronger sense of structure, but the taste is slightly harder, which is suitable for consumers who pursue a stronger chewing experience. The moisture content of the tablets is 4.2%, maintaining good storage stability.

[0077] Example 3: Effects of different sugar combinations on the taste of milk tablets

[0078] Material composition:

[0079] Milk powder (50%).

[0080] Corn syrup solids (10%).

[0081] Edible glucose (35%): Glucose is used to replace part of lactose to enhance sweetness and chewiness.

[0082] Soluble dietary fiber (5%).

[0083] Process steps:

[0084] The same process flow as Example 1.

[0085] Effect evaluation: The glucose in this formula makes the sweetness of the milk tablets more intense, and the tablets have a softer taste when chewed, and melt in the mouth. The moisture content is 3.8%, which is well maintained during storage.

[0086] Comparative Example 1: Milk flakes without particle homogenization

[0087] Material composition:

[0088] Milk powder (50%).

[0089] Lactose (30%).

[0090] Soluble dietary fiber (15%).

[0091] Microcrystalline cellulose (5%).

[0092] Process steps:

[0093] All materials are directly mixed without being crushed or homogenized and are directly tableted.

[0094] The tableting pressure was 8 MPa and the temperature was 35°C.

[0095] Effect evaluation: Due to the lack of particle homogenization, the texture of the milk tablets is relatively rough, the granular feeling is obvious when chewing, the tablet surface is uneven and prone to cracks, affecting the appearance and taste. The moisture content is 4.5%, and the tablets are prone to agglomeration during storage.

[0096] Comparative Example 2: Milk tablets with reduced milk powder ratio

[0097] Material composition:

[0098] Milk powder (30%).

[0099] Lactose (30%).

[0100] Corn syrup solids (30%)

[0101] Soluble dietary fiber (10%).

[0102] Process steps:

[0103] The same process flow as Example 1.

[0104] Effect evaluation: The reduction in the proportion of milk powder makes the milk tablets less milky, and the taste is relatively simple and not smooth enough, which affects the overall experience of consumers. The tablets are hard and have a poor chewing feel.

[0105] Based on the comparison between the above-mentioned Examples 1 to 3 and Comparative Examples 1 and 2, it is clearly demonstrated that the composite powder particle design of the present application example plays a key role in improving the taste and chewing experience of the tablet food. The homogenization of the particles, the reasonable combination of milk powder and sugars, and the appropriate addition of fiber can significantly improve the texture and taste of the tablet food. However, if the particles are not homogenized or the proportion of the ingredients is unreasonable, the tablet food will have a rough texture and a poor taste.

[0106] The embodiment of the present application also provides a tablet food, which is prepared by the preparation method of the tablet food of the above embodiment. The above preparation method optimizes the formula design, so that the taste level of the tablet food is richer, and the consumer experience is significantly improved; the above preparation method also optimizes the raw material processing process of the tablet food. Specifically, by homogenizing the particles of the raw materials, the texture of the tablet food is more uniform, and the granularity and agglomeration phenomenon are reduced; in addition, the weight proportion of medium-sized particles in the tablet food prepared by the above method is 20% to 30%, the weight proportion of fine particles is 70% to 80%, and the moisture content is maintained at 3% to 5%, so that the tablet food can achieve the best chewing feeling (neither too hard nor quickly disintegrated in the mouth, and can maintain moderate hardness and crispness when chewing), that is: it has good brittleness, and maintains moderate softness and taste level, solving the taste problem existing in the prior art.

[0107] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
