Description

{Manufacturing method of berry powder}

More particularly, the present invention relates to a method for producing a beryllium powder having a high concentration of a liquid material made of a beryllium having a high sugar content, in order to prevent a yield reduction problem and a caking problem To a method for producing a beryllium powder.

Berry contains a lot of antioxidants such as anthocyanin pigment, so it is a super food useful for beauty and immunity enhancement. Such berries include, for example, Aronia berry or Blackcurrant berry, Blueberry, Acai berry, Maqui berry and Strawberry (Fragaria ananassa Duch).

Berries can be eaten raw, raw or juiced or concentrated to make liquid and then taken. However, unprocessed berries are bulky, difficult to transport, store and transport, and even if the berries are made into liquid form, they are still bulky and hard to be solved. Accordingly, there has been disclosed a method of pulverizing berries, more preferably, powdering berries to a high concentration for convenient handling and ingestion as well as carrying, transportation and storage of berries.

The powders are classified according to their diameters. Powders having a diameter of about 10 占 퐉 or less are referred to as micron powers. Powders having a diameter of about 10 占 퐉 to 1 mm are referred to as powders or fine granules. do.

In general, berries have a high sugar content, so even if they are heated and concentrated, powdering is not easy. Particularly, it is more difficult to powder at high concentration. Furthermore, since berries are caking by absorbing moisture even if they are pulverized at a high concentration, there is a problem that the berries must be pulverized again.

There is a spray drying method in which a liquid material having a high sugar content is pulverized by a spray dryer in which a liquid sample is sprayed with a small droplet and then hot air is blown dry to obtain a powder. Further, in the conventional method of granulating a liquid material having a high sugar content, seed particles such as modified starch are flowed in a fluidized bed apparatus, and a liquid sample is sprayed in a small droplet state in this state, There is a fluidization method in which a droplet is repeatedly attached and coated to grow into a circular granule through grapevine-shaped particles.

Korean Patent Publication No. 10-1481772 discloses a method for producing a granule or a ring containing an extract at a high concentration. In the same manner as in the prior art, a liquid material to be highly concentrated is pulverized in a spray dryer , A fine granule is produced by spraying purified water or a liquid material in a top-spray manner in a state where a powder of a liquid material to be high-concentration is flowing, and a fine particle such as a seed particle such as a conventional modified starch Spraying the liquid material in a bottom-spray manner in a state in which the fine granules are flowed as seed particles, and allowing the liquid material to stay in a fluidized state for a predetermined time to produce high-concentration granules, A method of improving storage and distribution stability by coating with a material is disclosed.

However, according to the above-mentioned prior art, the powdery material is absorbed into the chamber of the spray dryer in the process of pulverizing the liquid material having a high sugar content in the spray dryer, thereby lowering the pulverization yield and caking the powder. Lt; / RTI > In addition, the above-mentioned prior art documents a problem that the fluidity is insufficient even in the process of granulating a liquid material having a high sugar content in a fluidized bed apparatus, the seed formation yield is decreased and the granules are adhered to the fluidized bed apparatus, resulting in lowering of the granulation yield, The problem of caching may still occur.

Hereinafter, preferred embodiments of the present invention will be described. However, the embodiments of the present invention can be modified into various other forms, and the scope of the present invention is not limited to the following embodiments. In addition, to include an element throughout the specification does not exclude other elements unless specifically stated otherwise, but may include other elements.

The beryllium powder produced by the production method of the present invention means any one of a powder having a diameter of 10 μm or less, a powder having a diameter of 10 μm to 1 mm or a fine granule, and a granule having a diameter of 1 mm or more will be.

In the present invention, berries are limited to liquid materials having a high sugar content. Thus, the liquid phase may be a juice of berries or a concentrate thereof, and the concentrate may be used in the same meaning as the juice solution.

Referring to FIG. 1, in a method for producing a beryllium powder according to an embodiment of the present invention, a concentrate containing berries is first prepared, and a mixed solution is prepared by mixing the concentrate with a powdered base as an excipient (S10). Preferably, the dextrin may include 50 to 70 parts by weight, and the porous dextrin may include 3 to 12 parts by weight, based on 100 parts by weight of the concentrated vermiculite.

The powdered base material includes porous dextrin having a specific cost of 5.4 ml / g and a specific surface area of 0.36 m2 / g as shown in Fig. 2, in addition to ordinary dextrin as an excipient. 2 is a microscope photograph of the porous dextrin used in the present invention. By reducing the specific gravity of the spray dried powder according to the present invention, the porous dextrin increases the fluidity as a seed of the spray dried powder in the fluidization step for granulation to be described later, prevents moisture absorption, improves dissolution and dispersibility, And the like.

At this time, the mixed solution may be prepared by further adding sodium octenyl succinate (S11). The octenyl group of sodium octenyl succinate is excellent in lipophilicity, cold water solubility and film forming property, and can improve the spraying and moisture-proofing effect. In this spraying process, the solubility of the beryllium concentrate is increased to help spraying, The dried powder can be prevented from reabsorbing moisture, thereby preventing loss of moisture absorption and caking phenomenon in the spray drying process and improving the powder yield. At this time, sodium octenyl succinate may preferably be added in an amount of 3 to 7 parts by weight based on 100 parts by weight of the beryllium concentrate.

Next, the mixed solution is sprayed at a spraying rate of 500 to 1,000 ml / hour by a spray dryer having an inlet temperature of 180 to 200 ° C and an outlet temperature of 95 to 105 ° C to produce spray dried powder (S20).

On the other hand, such spray dried powder can be made into powder of granules, if necessary.

For this purpose, the spray dried powder is introduced into the fluidized bed apparatus through a seed to proceed with the first fluidization. At this time, the spray dried powder is sprayed with purified water or a concentrate of the same kind as the spray dried powder by a top-spray method at 70 ° C, and the spray dried powder is coated and dried to have a diameter of 50 to 500 μm Lt; RTI ID = 0.0 > (S30). ≪ / RTI >

When the spray dried powder is sprayed with the purified water or the concentrated liquid during the fluidization, liquid phase crosslinking is formed between the powder particles, and then, when water is evaporated, agglomerates of 3 to 4 powder particles are formed by solid crosslinking. Then, when the fine powder particles are continuously bonded, a ruby granule is formed. In the top-spray method, while the powder is moving from bottom to top, the purified water or concentrate sprayed in the upper part of the direction of movement of the powder is sprayed downward from the top, and the force And the chance of forming a liquid cross-linking between fine particles is further increased due to an increase in the friction force or the frequency of contact between particles.

On the other hand, in the conventional powder production method, the surface of the granules is coated with a moisture-proof coating material, but in this embodiment, ascorbyl palmitate may be further contained in the concentrate of the same kind as the purified water or the spray-dried powder (S31) . The ascorbyl palmitate is preferably added in an amount of at least 3.8% by weight based on 100 parts by weight of the total.

Next, the microgranules are fed into the fluidized bed apparatus as a seed to proceed the secondary fluidization. At this time, a concentrate of the same kind as that of the spray dried powder may be sprayed on the fine granules by a bottom-spray method to grow granules having a diameter of 1 mm or more (S40).

At this time, ascorbic palmitate may be further contained in the concentrate as in the first fluidization process (S41). The ascorbyl palmitate is preferably added in an amount of at least 3.8% by weight based on 100 parts by weight of the total.

Thereafter, the granules may be further pulverized. The ascorbyl palmitate prevents caking of the granules to improve storage and distribution stability, and prevents lipids such as anthocyanin, which is an antioxidant of berries, from being oxidized and oxidized during the fluidization process. Therefore, as in the present embodiment, when ascorbyl palmitate is used in the production of fine granules and granules, the phenomenon of caking, in which the pulverized powder is united again, does not occur even if dry grinding is performed.

Generally, when a spray drying operation is performed, a concentrate is used. The solid content of the concentrate is important for spray drying. If the content of saccharides in the concentrate of the concentrated liquid is high, spray drying may not be performed well, or the dried product may not be flowable in the chamber of the spray dryer, and a large amount of dried components may adhere to the product. That is, even when the spray drying condition is constant, the critical point of the obtained yield varies depending on the kind of the concentrated liquid and the sugar content. Therefore, when the concentration of the concentrated liquid is increased to a high concentration, the spray drying operation becomes difficult or impossible.

It is difficult to dry a concentrate of a fruit ingredient which is a high-content food material, and even if it is dried by a spray drying method in which a concentrate is mixed with dextrin or the like and dried, it is difficult to contain a certain amount, that is, a solid content of a concentrate in general, by 30% or more. Significantly lower. Generally, 30% of the solid content of the berry concentrate acts as a critical point, depending on the composition and physical properties of the concentrate. Therefore, if it contains 30% or more based on the solid content, it can be said as a high-concentrated fruit juice powder.

Also important for the fruit concentrate is the concentration of the concentrate itself, i.e., the solid content contained in the concentrate. That is, when juice is extracted from fruit, the solid content is generally 4 to 12%, and it is manufactured and distributed at a concentration of 55% (55 brix) or more, generally 65 brix or more for enhancing storage stability and for convenience of nutrients.

According to the present embodiment, first, a part of the concentrated liquid at a high concentration is spray-dried and pulverized, and then the remaining concentrate is sprayed using a fluidized bed granulator to prepare granules. The concentration is maximized to 70% A beryllium powder having a high concentration of juice or concentrate content can be obtained.

Table 1 below shows a powdery base material added to a beryllium concentrate and sprayed with a spray dryer to produce spray dried powder, and the yield of the powder was checked. 30 g of the beryllium concentrate is used in an amount of 300 g, the total content of the powdered base material is 210 g, and the yield of the produced powder is 300 g, the yield is 100%. In Comparative Example 1, dextrin was used as a powdered base material. In Comparative Example 2, dextrin and sodium octenyl succinate were used as powdered base materials.
