Description

Technical Field

[0001] The invention belongs to the technical field of sugar alcohol preparation, and particularly relates to a method for improving the agglomeration of powdered maltitol. Background Art

[0002] The preparation method of powdered maltitol is to directly prepare it from crystalline maltitol through a powder breaking process and powder breaking equipment. Powdered maltitol has the following characteristics: large contact area, porous structure and strong hygroscopicity, while crystalline maltitol has the characteristics of large particles, compact structure and uniform particle size. Therefore, powdered maltitol is easier to agglomerate than crystalline maltitol.

[0003] In order to prevent powdered maltitol from agglomerating, the following methods are usually adopted: 1. Adding anti-caking agents. Although the anti-caking effect is significant, it increases production costs and may also affect the taste or flavor of the product, and some customers may not even accept it; 2. Controlling the temperature and humidity of the environment. The cost is low and will not change the properties of the product itself, but it has high requirements for the environment and requires special equipment to control the humidity, and the effect is unstable; 3. The product is vacuum packaged. Although it can effectively isolate moisture in the air and prevent agglomeration, the packaging cost is high and the operation is complicated, which is not suitable for large-scale production. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a method for improving the agglomeration of powdered maltitol. The crystalline maltose used for preparing the powdered maltitol is first subjected to aging and drying treatments before being subjected to a powder breaking treatment, thereby improving the agglomeration phenomenon of the powdered maltitol from the source of raw materials, reducing the agglomeration phenomenon of the powdered maltitol, and extending the shelf life.

[0005] The present invention is implemented in this way, providing a method for improving the agglomeration of powdered maltitol, comprising the following steps: directly transferring the prepared crystalline maltitol into an aging bin for 24 hours of aging treatment, packaging the aged crystalline maltitol into ton bags and transferring it into a normal temperature warehouse for storage for 4 days, then unpacking the crystalline maltitol, using a drying tank for drying treatment, and finally breaking the dried crystalline maltitol into powder to obtain powdered maltitol, and storing the powdered maltitol in separate packages.

[0006] The present invention performs a drying treatment on the crystal maltitol after the first aging treatment and transfer storage, thereby interrupting the water migration and absorption and dissipation inside the crystal maltitol, that is, destroying the agglomeration process inside the crystal maltitol, thereby improving the agglomeration phenomenon of the powdered maltitol obtained after the powder breaking treatment. The present invention improves the easy agglomeration phenomenon of the powdered maltitol from the source of raw materials, reduces the agglomeration phenomenon of the powdered maltitol, and prolongs the shelf life of the powdered maltitol.

[0007] Furthermore, the temperature of the aging bin is 23-28°C, the humidity is below 25%, and the air volume is 1000-3000N / m 3 .

[0008] Furthermore, the temperature of the normal temperature warehouse is 25-28°C and the humidity is below 50%.

[0009] Furthermore, the conditions for the drying treatment are: the temperature of the drying tank is 20-30° C., and the humidity is below 50%.

[0010] Furthermore, the powder breaking treatment refers to grinding the dried crystalline maltitol by an airflow vortex mill, and the particle size of the powdered maltitol after grinding is less than 60 meshes.

[0011] Furthermore, the sub-packaging and storage of the powdered maltitol refers to sub-packaging the powdered maltitol in two-layer PE bags, and placing a desiccant bag in the inner PE bag containing the powdered maltitol; and then packing and storing in a normal temperature warehouse.

[0012] Compared with the prior art, the method for improving the agglomeration of powdered maltitol of the present invention uses crystalline maltitol to break powder to obtain powdered maltitol, and before the crystalline maltose is broken powdered, it is first aged, transferred and stored and dried, and the powdered maltitol obtained by the powdering process is packaged and stored. The present invention improves the easy agglomeration phenomenon of powdered maltitol from the source of raw materials, reduces the agglomeration phenomenon of powdered maltitol, and prolongs the shelf life of powdered maltitol. In addition, since it is not necessary to add an anti-caking agent to the powdered maltitol, the mouthfeel of the powdered maltitol product will not be changed. Moreover, the method of the present invention is suitable for large-scale production, and further realizes the reduction of production costs. DETAILED DESCRIPTION

[0013] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Example 1

[0015] Specifically, the temperature of the aging bin is 23-28°C, the humidity is below 25%, and the air volume is 1000-3000N / m 3 .

[0016] Specifically, the temperature of the normal temperature warehouse is 25-28°C, and the humidity is below 50%.

[0017] Specifically, the drying process is carried out under the following conditions: the temperature of the drying tank is 20-30° C., and the humidity is below 50%.

[0018] Specifically, the powder breaking treatment refers to grinding the dried crystalline maltitol by an airflow vortex mill, and the particle size of the powdered maltitol after grinding is less than 60 meshes.

[0019] Specifically, the sub-packaging and storage of the powdered maltitol refers to sub-packaging the powdered maltitol in a two-layer PE bag, and placing a desiccant bag in the inner PE bag containing the powdered maltitol; then packing and storing in a normal temperature warehouse. The thickness of the PE bag is 0.10 mm. Each box contains 25 kg of powdered maltitol product.

[0020] The effect of the method for improving the agglomeration of powdered maltitol according to the present invention is further illustrated by comparative examples below.

[0021] Comparative Example 1 The difference between this comparative example and Example 1 is that the aged crystalline maltitol is not packaged in ton bags and transferred to a normal temperature warehouse for storage for 4 days, but is directly dried after aging for 24 hours. The other steps and conditions are the same as those of Example 1.

[0022] Comparative Example 2 The difference between this comparative example and Example 1 is that the prepared crystalline maltitol is not subjected to 24-hour aging treatment and 4-day transfer storage treatment, but is directly subjected to drying treatment. The other steps and conditions are the same as those of Example 1.

[0023] The powdered maltitol prepared in Example 1 and Comparative Examples 1-2 were subjected to storage aging experiments.

[0024] The method of the storage aging experiment is: store the test samples under the same environmental conditions, observe the properties of the test samples at 7 days, 20 days, and 33 days of storage, and visually confirm the degree of agglomeration of the test samples.

[0025] The same quantity and same packaging of powdered maltitol prepared in Example 1 and Comparative Examples 1-2 were selected for storage aging test to obtain the results shown in Table 1.
