Description

Detailed Description of the Invention

  The present invention relates to a method for producing a powder article by extracting an active ingredient from a biological material or a processed biological material with a liquid solvent, or mixing a liquid solvent with a biological material or a processed biological material and drying it. It relates to sterilization technology that does not degrade the quality.

  Although powdering of articles is a technique that has been performed for a long time, it is still widely practiced because it has advantages such as convenience in handling powder and good storage stability. In particular, recently, it has become popular to use powders of target components prepared in advance for the purpose of using difficult-to-use natural components such as natural flavors, natural seasonings or natural medicinal components. Thus, for example, the importance of powdered foods is increasing. Green tea beverages that are currently produced and consumed in large quantities are typical examples of their use.

  By the way, since such a powder sometimes uses a natural product as a raw material in a form close to a natural material, various difficulties have been associated with its sterilization. This may be due to poor sterilization efficiency due to complex properties, or alteration due to instability of components. For this purpose, various methods have been devised, proposed and implemented.

  As a sterilization method for powder articles, a heat sterilization method is generally performed. Patent Document 1 proposes a method for producing a powdered food as a method for improving the efficiency of heat sterilization and preventing quality deterioration. In the sterilization method using heated steam, a granular auxiliary agent having a larger diameter than the intended powder is added and mixed, and after the mixture is sterilized by heating while being suspended in a stream of heated steam, the granular auxiliary agent is removed, It is said that viable bacteria, spore bacteria, etc. can be easily sterilized without impairing the flavor, flavor, active ingredients, etc. of the powdered food.

  Further, as a method for sterilizing spices, a method is also proposed in which a sterilizing solution in which acetic acid and clove oil or cinnamon oil are dissolved or dispersed in ethanol or hydrous ethanol is sprayed on the spice or its crushed or pulverized product and heated with an extruder. (Patent Document 2).

On the other hand, as a method for sterilizing raw materials before pulverization, a method for producing radish powder has been proposed (Patent Document 3). By the manufacturing method including the step of sterilizing by immersing in an acidic solution and the step of freeze-drying and pulverizing it, contamination by bacteria during the manufacturing process is prevented.

  Hereinafter, the best mode for carrying out the present invention will be described. However, this description is based on the purpose of specifically explaining the present invention and contributing to an accurate understanding of the contents of the invention. These descriptions do not represent typical examples of the present invention, and are not intended to limit the scope of the present invention by this description.

  First, the biological material used in the present invention or a processed product of the biological material is the whole and a part of all the biological materials of the eubacteria kingdom, archaea kingdom, protist kingdom, fungus kingdom, plant kingdom, animal kingdom, Or it is at least 1 type chosen from the group which consists of those processed goods. Any material can be used as long as it can produce a powder article containing an active ingredient using these as raw materials. Therefore, the form is not particularly limited, such as an original shape, a cut product, a pulverized product, a paste product, and an extracted product, and may be any shape as long as it can be processed by currently known processing techniques. In addition, examples of specific powder articles produced by applying the present invention include seasonings, raw materials for taste beverages, fragrances, coloring agents, nutrients, quality improvers, medicines, natural preservatives, antibacterial agents Agents, insect repellents, repellents.

  In addition, the extraction, mixing, and concentration steps in the present invention need not be limited to specific methods, and any method may be used as long as ethanol, salt, acetic acid, or the like can be used or heat treatment is possible. From the known methods, it is possible to appropriately select a method optimal for the material and the properties of the article to be generated.

  In addition, the drying process in the present invention can be performed by any method, but in order to maximize the effects of the present invention, methods such as spray drying, drum drying, and hot air drying have little quality deterioration, and sufficiently exhibit the bactericidal effect. Suitable for Further, if necessary, ethanol or acetic acid may be volatilized during the drying step to adjust the ethanol or acetic acid concentration in the powder. Moreover, you may add well-known powdered base materials, such as dextrin and starch, in drying.

  In addition, the step of adding ethanol in the present invention may be at least one of the processing steps including extraction, mixing, concentration, and drying. For example, even if it is added in the extraction or mixing step and then ethanol is lost during concentration or drying, the bactericidal effect is exhibited.

  The amount of ethanol used in the present invention is not particularly limited, but is preferably 0.1% by weight or more and 90% by weight or less of the mixed weight of the biological material or biological material processed product and the liquid solvent, more preferably 1% by weight or more and 70% by weight or less. This is because if the addition rate is less than 0.1% by weight, the bactericidal effect may be weak, and if it exceeds 90% by weight, the quality may be impaired, and there may be a problem in economic efficiency. .

  The amount of sodium chloride used in the present invention is not particularly limited, but is preferably 1% by weight to 26% by weight, more preferably 5% by weight based on the total weight of the biological material or the processed biological material and the liquid solvent. % By weight or more and less than 26% by weight. If the amount is less than 1% by weight, the bactericidal effect may be weak. If the amount is 26% by weight or more, salt may be precipitated in the process or product. Even if sodium chloride is added to a liquid solvent or added to a biological material or a mixture of biological materials and a mixture of the liquid solvent, there is no difference in effect.

  The amount of acetic acid used in the present invention is not particularly limited, but is preferably 0.1% by weight to 95% by weight of the total weight of the biological material or the processed biological material and the liquid solvent, more preferably Is 1% by weight or more and less than 50% by weight. If it is less than 0.1% by weight, the bactericidal effect is weak, and if it is 95% by weight or more, the quality may be affected.

  In addition, the heating step in the present invention is not particularly limited, but it can be sterilized more efficiently by heating in at least one step of a group consisting of extraction, concentration, and drying. The heating temperature is not particularly limited, but the bactericidal effect becomes higher at 30 ° C. or higher and 120 ° C. or lower, and is more effective at 40 ° C. or higher and 100 ° C. or lower. This is because the sterilizing effect may be insufficient at 30 ° C. or lower depending on the type of the material, and the possibility that the quality deteriorates at 120 ° C. or higher becomes high. The total time of heating at these temperatures is desirably determined by the heating temperature, but under the above-mentioned temperature conditions, 0.5 minutes to 120 minutes, preferably 0.5 minutes to 60 minutes, and sufficient sterilizing effect. is there. If it is 0.5 minutes or less, the bactericidal effect may be weak, and if it is 120 minutes or more, the quality may deteriorate.

  Hereinafter, the present invention will be specifically described with reference to examples, but the present invention is not limited to these examples.
