The present invention relates to a method for producing a liquid seasoning, and more particularly, to a method for producing a liquid seasoning, and more specifically, the present invention relates to a method for producing a liquid seasoning.
The present invention relates to a method for producing a homogeneous and stable liquid seasoning by delaying or preventing crystal precipitation of sodium inosinate. Seasonings come in various forms such as powders, granules, cubes, pastes, and liquids, but for example, in the case of those containing animal and plant extracts, the taste due to drying,
Liquid seasonings are popular because they cause less deterioration in flavor, do not require consideration of changes in physical properties due to moisture absorption, etc., are easy to dissolve seasonings, and do not contaminate the working environment. Liquid seasonings contain animal and plant extracts, various amino acids, their salts, various organic acids, their salts, and various other tastes, flavor components, fragrances, and spices. In order to improve the storage stability, which is particularly problematic due to the liquid state, without using synthetic preservatives, it is effective to incorporate common salt at a relatively high concentration. When 5'-inosinic acid and its salts are added to such a liquid seasoning with a high salt concentration, the solubility of sodium 5'-inosinate decreases, which impairs the quality stability and homogeneity of the product. cause problems. Figure 1 shows the solubility of common salt and sodium 5'-inosinate; as the salt concentration increases, the 5'-
The solubility of sodium inosinate decreases; at room temperature, for example, when the salt concentration is 5 to 10%, the solubility of sodium 5'-inosinate decreases to 1 to 5%. The solubility of sodium 5'-inosinate tends to be the same even in liquid seasonings prepared with a combination of multiple ingredients. Therefore, if a liquid seasoning in which sodium 5'-inosinate is completely dissolved at room temperature is stored at a low temperature or left at a low temperature in winter,
The solubility of sodium 5'-inosinate decreases and crystal precipitation occurs. Alternatively, if sodium 5'-inosinate is contained in a high concentration, the addition of common salt may be restricted, or crystals of sodium 5'-inosinate may precipitate even at room temperature. The growth of crystals changes depending on temperature conditions and storage time, but the crystals grow large enough to be observed with the naked eye.
Depending on the conditions, the crystals may form long needle-like crystals, which may become the subject of claims as foreign substances. Furthermore,
Crystals vary in size, making uniform mixing, dispersion, and floating difficult. Particularly when using small quantities from large-capacity containers, variations in taste etc. become a problem. Generally, in such cases, there are methods such as increasing the temperature to redissolve the 5'-sodium inosinate before use, or lowering the salt concentration in the seasoning solution to increase the solubility of the 5'-sodium inosinate. However, none of these methods is necessarily satisfactory in terms of storage stability, ease of use, etc. The present inventors discovered that 5'-
In liquid seasonings containing sodium inosinate
As a result of intensive studies aimed at eliminating the precipitation of sodium 5'-inosinate crystals, we found that 5'-inosinic acid containing amino acids and their salts (excluding Na salts), and/or inorganic salts (excluding Na salts) The present invention was completed based on the finding that by adding sodium at a molar concentration or higher, crystal precipitation of nucleic acids can be prevented and a liquid seasoning with excellent storage stability and homogeneity can be obtained. The liquid seasonings targeted by the present invention include common salt and
All liquids or pastes containing sodium 5'-inosinate are included, and the types and numbers of other ingredients are not limited. Namely, seafood extract, animal extract, yeast extract, bone extract, hydrolyzed animal protein (HAP), hydrolyzed vegetable protein (HVP), various other extracts, monosodium glutamate and other amino acids and their salts,
It may be composed of any component selected from among organic acids and their salts, natural or artificial sweeteners, fats and oils, etc. as required. Salt, as table salt or as salt contained in soy sauce, miso, and other salt-containing seasonings, has a concentration of 5% to 25% in the final product, but at this concentration, it is in a microbially stable liquid or can be provided as a pasty seasoning. The concentration of sodium 5'-inosinate is less than 5% and greater than its solubility. Amino acids added to the liquid seasoning include glycine, aspartic acid, etc., and calcium salts, potassium salts, magnesium salts, hydrochlorides, etc. of these amino acids can also be used. Further, as inorganic salts, magnesium chloride, potassium chloride, etc. can be added. 1 selected from the above amino acids and their salts (excluding Na salts) and inorganic salts (excluding Na salts)
5'- Containing seeds or two or more seeds in liquid seasonings
It is added at a molar concentration equal to or higher than that of sodium inosinate. If the added concentration is less than the molar concentration of sodium 5'-inosinate, the crystal precipitation delaying or preventing effect of sodium 5'-inosinate will not be sufficient, but if the concentration is too high, the solubility of other components will be reduced. The optimum concentration is 20 times the molar concentration of sodium 5'-inosinate contained therein, since this may cause the taste to become unbalanced. There are no particular limitations on the order of addition of salt, nucleic acids, amino acids, inorganic salts, and other components added as necessary, sterilization method, etc. The liquid seasoning obtained by the method of the present invention is in the form of liquid, slurry, paste, etc., and can be used as it is or by diluting with water, hot water, etc. to prevent scattering or
Seasonings and seasoned foods with excellent flavor are obtained without the formation of lumps, and there is no precipitation of nucleic acid crystals during the distribution and storage stages, and they are microbially stable, so they are widely used as liquid seasonings. We can expect it to have many uses. The present invention will be further explained below with reference to Examples. Example 1 Formula of liquid seasoning (A) Glycine 10 parts Salt 10 Water 80 IMP・2Na・7.5H 2 O 3 Control formulation Salt 10 parts Water 90 IMP・2Na・7.5H 2 O 3 According to the above formulation , the temperature at which nucleic acid crystals can be sufficiently dissolved in the salt-water (-evaluation substance) system (80°C)
After dissolving the nucleic acid crystals, they were kept at a constant temperature (20°C) for a certain period of time. Next, it was cooled to a temperature lower than the saturation temperature, and the time from the start of cooling until the end of precipitation of crystals was measured. The results are shown in Table 1.
