Encapsulation to produce a fine particulate powder.

Prior art related to the present invention is U.S. Patent No. 3,041,180, which uses glycerol and corn syrup as carrier materials to inject 2 to 15% of essential oil components into a cold organic solvent (refrigerant) and finely pulverizes the surface. A series of methods of separating and then separating and drying the solvent has become a technique widely used in the extrusion method. U.S. Patent No. 3,704,137 uses sugar and dextrins of DE 10-15 as coating material and adds antioxidants to essential oils to provide an antioxidant effect and to separate the solvent by centrifugation. U.S. Patent No. 5,009,900 discloses a twin extruder by mixing a nuclear material to be encapsulated in a raw material (e.g., Succinyl modified starch and dextrins) that becomes a vitreous matrix (Glassy matrices) to encapsulate volatiles using conventional extrusion techniques. According to the Republic of Korea Patent Publication No. 10-0539427, using sesame oil instead of essential oil (essential oil), Dex 200 powder and hymaltose as a coating material, isopropanol and nucleic acid as a refrigerant And the use of a hydraulic extruder as the extruder is different from the conventional patent.

The present invention melts the coating carrier material at a high temperature to form a transparent glassy (Molten mass) carrier in a molten state, mixes and emulsifies with the nuclear material, extrudes into a cold refrigerant, and rapidly cools and crystallizes. Sesame oil is encapsulated in fine particles to make powder. Therefore, the appropriate amount of water acts as a plasticizer of the carrier material to stabilize the crystal when crystallized in a cold organic solvent after extrusion serves to protect the fragrance components. In addition, there is a technical goal to improve the manufacturing method, such as the type and amount of the emulsifier used, the degree of emulsification of the nuclear material and the carrier material, the problem of the conventional hydraulic vertical injection molding machine used during extrusion. In addition, since the conventional patents all use solvents that are not allowed to be used in the food hygiene law, it is impossible to put them to practical use, and the technical problems include applying them to the food additives.

In the manufacturing method of the sesame oil fine encapsulated powder product of the present invention, the mixed saccharide as a coating material is added to the reactor and heated and vitrified and melted, and then mixed with the vitrified concentrate by adding an emulsifier, and gradually adding sesame oil to homogeneously emulsify it. The emulsification stage,

An extrusion step in which the emulsion is put into an extrusion tube having an extruder plate of an extruder and extruded in a cold refrigerant with a compressed gas,

The solidified extrudate is pulverized, molded and dried to remove the refrigerant.

The emulsifying step may emulsify 30 to 45% polysaccharide, 20 to 30% disaccharide, 10 to 25% water, 7 to 20% sesame oil, and 2 to 5% emulsifier.

The polysaccharide used in the emulsifying step may be any one or more selected from maltodextrin, syrup, maltose syrup.

In the emulsifying step, the disaccharide may use any one or more selected from sugar, maltose, lactose, invert sugar and the like.

The emulsifier in the emulsifying step may be any one or more selected from lecithin, glycerin fatty acid ester, sucrose fatty acid ester.

In the extrusion step, the sesame oil emulsion may be extruded in a refrigerant or cold air.

In the extrusion step, the refrigerant may be extruded by maintaining the temperature of the alcohol at -18 ° C to 0 ° C.

In the extrusion step, the cold air may be extruded by maintaining the temperature at -18 ° C to 0 ° C.

Compression gas during extrusion of the emulsion in the extrusion step may use any one or more selected from nitrogen, carbon dioxide gas, compressed air.

In the extrusion step, the temperature of the reactor, the extrusion plate, the extrusion port, and the pipe during extrusion may be maintained at about 110 to 130 ° C.

The extruder in the extrusion step may use a diameter of the extrusion port of 0.1 ~ 2.0mm.

The present invention includes sesame oil microencapsulated products prepared by the above-mentioned method.

The present invention consists of a nuclear material (seed oil emulsion) and an outer coating material (vitrified carrier), an injection apparatus, and a rapid cooling method for collecting sesame oil inside.

<Composition ratio>

Nuclear material is composed of sesame oil and emulsifier. In general, lecithin is widely used as an emulsifier to collect sesame oil in a carrier material, the outside of which is liberated with amorphous crystals such as candy. The sugar concentrate, which is basically a coating material, is widely used in the confectionery industry but is a technology that requires a high level of know-how. Improperly prepared sugar concentrates are solidified and, as time passes, the water content is increased with the original moisture and the moisture absorbed in the air, and the crystallization progresses from the outside to the outside. Therefore, the cracks on the coating material (feeling cracks), it feels gritty on the tongue, the inner nuclear material is exposed to the outside, the loss of the fragrance components or oxidation proceeds to deteriorate the quality. Factors that greatly influence the progress of crystallization of sugar concentrates are the type of sugar and the water content of the finished product. Sugars here are mainly sugar, syrup (Glucose Syrup), invert sugar and maltose syrup. Maltodextrin is further used as the raw material used in the present invention. In addition, various raw materials such as modified starch, gum, and protein may be used. Maltodextrin has a high DE (Dextrose Equivelent) value, that is, a high glucose equivalent value, which inhibits the formation of crystals in the sugar concentrate and has a high air barrier property when solidified. Hygroscopicity at the time of contact, there is a limit to use. On the contrary, maltodextrin having a low DE value lowers crystallization inhibitory function and has low air barrier property, but is relatively effective for hygroscopicity. Therefore, the use of sugars in which polysaccharides (maltodextrin, starch syrup, maltose syrup, etc.) and disaccharides (sugar, maltose, lactose, invert sugar, etc.) are properly mixed, the functions of each raw material are complemented to obtain a good effect. Therefore, the present invention has studied the mixing ratio of the saccharides commonly used in the food industry to maximize the function as a coating material, the polysaccharides such as maltodextrin (DE 10-25) or starch syrup as polysaccharides 30 ~ 30 45%, disaccharides such as sugar, maltose, lactose, or invert sugar are 20 to 30%, water is 10 to 25%, sesame oil is 7 to 20%, and emulsifier is lecithin, glycerin fatty acid ester, sucrose fatty acid ester, etc. The compounding ratio which consists of 5% was obtained.

<Refrigerant>

Basically, rapid cooling of the molten mass turns into amorphous and glassy like solids, which provides the ability to tightly block internal nuclear material. At this time, the requirement for the provision of the refrigerant should not dissolve the coating material, have good thermal conductivity, be easily removed in the drying process, be easy to work with, safe to use, and be usable under the Food Sanitation Law. In the prior art, Korean Patent No. 10-0539427 uses hexane or isopropyl alcohol as the refrigerant, but the refrigerant function is excellent, but the hexane or isopropyl alcohol is not allowed for the purpose of extracting the surface oil component under the current food hygiene law. There is no. For the practical use of the rapid cooling method, it is necessary to use a suitable refrigerant or cooling technology. In the present invention, a method of using a refrigerant uses alcohol (fermentation) permitted as a food additive, and a method of not using a refrigerant uses dehumidification, deoiling, and filtered cold air.

<Extrusion method>

In the extrusion method of pushing the emulsion to the injection plate, Korean Patent No. 10-0539427, which is a prior art, uses a hydraulic extruder and is preheated before use. In the end, this is not possible in a continuous manner and can be operated only in batch type, and once a problem arises in operation, the contents are hardened to operate because the contents are hard to operate. It is an extrusion method having a defect that must be made. The extruder of the present invention is equipped with an extruder tube and an extruder plate at the bottom of the reactor, and uses a compressed gas (nitrogen, carbon dioxide, air) as the power of the extrusion to extrude the refrigerant at the top of the emulsion in the closed reactor, so the method of use is very simple. It is easy to manufacture. In addition, even if batch production, one batch can be injected in one extrusion plate installation operation. Even in the case of the pump type, in order to maintain the temperature of 110-130 ° C, all lines are insulated with high-pressure hot water (120 ° C) and pressurized by the power of a sanitary metering pump equipped with an inverter. Work is possible.

The present invention is slowly heating and concentrating the saccharide mixture of the above mixing ratio in a stainless steel reactor to which a high pressure steam jacket is attached to form a vitrified matrix having a certain water content, and then adding lecithin and sesame oil. After high speed stirring and emulsification, the emulsion is transferred by pump or pressurization, and the emulsion is solidified by extruding the emulsion at a constant speed maintained at -18 ° C to 0 ° C or by using a cold air of -18 ° C to 0 ° C. . As described below, the surface oil is removed by pulverizing and immersion stirring in a refrigerant, an organic solvent is separated, dried under reduced pressure, a particle size sorting operation and an anti-solidification agent are added, followed by packaging to prepare a sesame oil fine encapsulated powder product.

Hereinafter, the content of the present invention will be described in detail through examples. However, these are intended to explain the present invention in more detail, and the scope of the present invention is not limited thereto.

<Example 1>

Sesame oil fine encapsulated powder product was prepared using the manufacturing process diagram of FIG. 1.

Add 1,000 g of purified water to the reactor (10 liters) according to the mixing ratio of Table 1, and slowly inject 1,150 g of hymalto syrup (more than 82 brix, maltose content: 70% or more, Sindongbang CP products) while stirring at 150 rpm. Allow the syrup to dissolve completely in water. And 1900 g of powdered syrup (DE about 23, the target product) is added to the previously dissolved syrup aqueous solution little by little while continuously stirring to ensure that the contents do not clump well. After confirming that the powdered syrup, hymaltos syrup and water were sufficiently mixed, 3 kg / cm 2 of steam was added to the reactor, and heating and heating were started at normal pressure while stirring. Viscosity begins to drop considerably from about 40 ° C. and rapidly drops as the temperature rises. Boiling starts around 100 ° C, the water inside the mixture evaporates in earnest (near 101-103 ° C), and the color of the mixture turns to dense white, and the temperature of the contents reaches around 116-126 ° C. When finished, it is very light brown and the vitrification concentration process is complete. Upon completion of the vitrification concentration process of the carrier material, 50-80 g / min, preferably 65 g / min, of lecithin (Solec 2F-UB, manufactured by Solae Company, USA) previously heated to about 60-70 ° C., preferably 65 ° C. Stir emulsification at 250 ~ 300rpm, preferably 275rpm so that the whole is well mixed while the input at a rate of. About 50-80 g / min of sesame oil (18 liters of old sesame oil products) heated beforehand to about 90-100 degreeC, preferably 95 degreeC, maintaining the temperature of melt at 110-125 degreeC, preferably 118 degreeC, Preferably it is emulsified at a rate of 65 g / min. The stirring speed for emulsification is 400 to 500 rpm, preferably 450 rpm, to homogeneously emulsify sesame oil, and then the stirring is stopped. All lines to the outside of the reactor after fastening the injection die (hole diameter: 0.4 to 2.0 mm, number of holes: 200 to 600) preheated to 120 to 130 ° C, preferably 125 ° C, to the bottom of the valve at the bottom of the reactor. To close it. The nitrogen gas is adjusted to a pressure of 3 to 4 kg / cm 2, preferably 3.5 kg / cm 2, and connected to the reactor. Instead of nitrogen gas, carbon dioxide or deoiled / dehumidified treatment can be used to filter compressed air with a microfilter. Nitrogen gas is added to the reactor and adjusted to 3 to 4 kg / cm 2, preferably 3.5 kg / cm 2, and the lower valve is opened. The emulsion is extruded into a cooling immersion tank containing refrigerant. The distance between the extrusion die and the surface of the refrigerant is maintained between 100 and 200 mm, preferably 150 mm, to maintain a constant size of filament. Factors that determine the diameter of the strand may be adjusted to the temperature of the emulsion, the extrusion pressure, the die hole diameter, the distance between the injection plate and the coolant, and the like to obtain a strand having a desired thickness. As the cooling method, alcohol was used as the organic solvent method, and cold air was used as the method that did not use the organic solvent.

-In the case of alcohol, it is used after cooling to -18 ℃ ~ 0 ℃, and the ejected emulsion pulled out into strands hardens rapidly in the refrigerant and solidifies. Impeller agitation (400-600 rpm) was immediately carried out in a cooling immersion tank containing the solidified injection strand (400-600 rpm), and the solidified strand (seed oil microcapsules) was cut to an appropriate size, followed by centrifugation to remove the refrigerant and then about 30-60 ° C., Vacuum drying at 400-720 mm Hg, preferably 45 ° C., 510 mm Hg until no residual solvent remained in the capsule preparation (see FIG. 2).

-In the case of cold air, extruded emulsion extracted with dehumidified / deoiled compressed air into a closed dry ice box and cooled by cold air at -15 ℃ ~ -5 ℃ by strands from about 100 ~ 200mm below the injection port. When fired, the emulsion hardens immediately and solidifies. This was pulverized to a certain size in an oscillator and sieved to a required particle size (5 to 40 mesh: 0.1 mm to 2.0 mm in pore size of the sieve) (see FIG. 3).

-The microcapsules prepared by the above two methods are then mixed by adding tricalcium phosphate (Tricalcium phosphate) to prevent solidification. Tricalcium phosphate prevents solidification, which is a phenomenon of sticking between particles due to hygroscopicity of the prototype as an anti-solidifying agent.
