<Industrial Application Field> The present invention relates to a method for producing an egg white decomposition product that can efficiently produce an egg white decomposition product that can be used in various foods, medicines, cosmetics, and the like. <Prior Art> Attempts have been made to use egg white decomposition products in various foods, cosmetics, etc., and various methods for obtaining this type of egg white decomposition products have been studied. For example, in Japanese Patent Application Laid-Open No. 58-155048, about 1 to 6%
After applying acidic proteolytic enzyme produced by Aspergis to raw egg white liquid with a protein concentration of approximately 80%
A method for producing an egg white hydrolyzate by heating the egg white to ~100°C and removing the coagulum is disclosed. In addition, JP-A-61-149071 discloses that a non-coagulable egg white solution with a protein concentration of 2 to 6% by weight is denatured by heating, then enzymatically treated with endopeptidase, and then reheated to produce processed egg whites. A manufacturing method is disclosed. <Problems to be Solved by the Invention> However, in the above-mentioned conventional method, aggregates are generated when adjusting the protein concentration to a predetermined level, and thermal decomposition products with low sedimentation properties generated during heat treatment after enzyme treatment are removed. The yield is low because it is difficult to
There was a problem that it was not practical for large-scale processing. In addition, egg white decomposition products produced by various conventional methods have a bitter taste or a strong umami taste, and therefore have the disadvantage that their range of use is limited. In view of these circumstances, an object of the present invention is to provide a method for producing an egg white decomposition product that can efficiently produce an egg white decomposition product that can be used in a wide range of applications. <Means for Solving the Problems> The structure of the present invention that achieves the above object is to dilute egg white with a lysozyme content of 2% or less per egg white protein with water so that the protein concentration is 3% or less, This diluted egg white is characterized by being treated with protease in an alkaline region. In the present invention, the lysozyme content per egg white protein is reduced to 2
% or less refers to a liquid whose lysozyme content is reduced to 2% or less per egg white protein by reducing the lysozyme content from egg white liquid by ion exchange method or the like, and its dried product. In other words, lysozyme is reduced from 5 to 6% of egg white protein, which is normally contained in egg white liquid, to 2% or less. Although various methods can be considered to reduce the lysozyme content to 2% or less, it is preferable to employ, for example, an ion exchange method or a salting method. Here, the ion exchange method is a method in which lysozyme is removed by adsorption to the ion exchange resin by bringing the egg white liquid into contact with an ion exchange resin such as a weakly acidic cation exchange resin, cation exchange gel, or cation exchange cellulose. It's a method. Furthermore, the salting method is a method in which salt is added to the egg white liquid to precipitate and remove lysozyme. Note that since the egg white liquid from which lysozyme has been removed by the salting method contains a large amount of salt, when using this egg white liquid, it is desirable to desalt it by passing it through a osmotic membrane filtration device or the like. Egg white liquid, which is the raw material for egg white with a lysozyme content of 2% or less per egg white protein, can be obtained in raw form by breaking chicken eggs and separating the egg yolk.
It may be thawed frozen egg white, dried egg white dissolved in water, or egg white liquid from which lysozyme has been removed. Note that if there is a large amount of egg yolk mixed into the egg white liquid, it will be difficult to obtain the desired egg white decomposition product, so it is desirable to use an egg white liquid with a small amount of egg yolk mixed in. In the present invention, egg white (hereinafter referred to as
(referred to as treated egg white) is added with water to obtain diluted egg white with a protein concentration of 3% or less. When diluting egg white with water in this way, if untreated egg white liquid was used as in the conventional method, agglomerates would occur, which was a problem, but the treated egg white used in the present invention does not cause any agglomerates and can be easily uniform. diluted egg whites. The reason for this is not clear, but it is expected that when normal egg white liquid is diluted with water to a protein concentration of 6% or less, lysozyme and other egg whites will form a complex.The present invention aims to prevent the formation of this complex. seems to be preventing it. Next, an alkaline agent such as caustic soda or caustic potash is added to the diluted egg white to adjust the diluted egg white to an alkaline range. The pH of diluted egg white is 7.5~10, preferably 8.0~
When adjusted within the range of 9.0, an egg white decomposition product containing a large amount of peptides with a molecular weight of 200 to 400 can be obtained. It should be noted that if the egg white solution used is already in the predetermined alkaline range, there is no need to adjust the pH. Furthermore, since diluted egg white contains sugar, if it is desired to produce an egg white decomposition product that does not contain sugar, it is advisable to desugarize the diluted egg white before the alkali adjustment step. Next, a proteolytic enzyme (protease) is added to the diluted egg white adjusted to an alkaline range, and the diluted egg white is treated with protease by maintaining the diluted egg white under a constant temperature condition for a certain period of time to obtain an egg white decomposition product. Proteolytic enzymes used in this treatment include papain, fuicin, promelain, pepsin, etc.
In addition to enzymes extracted from animal and plant tissues, enzymes derived from microorganisms, such as Amano A and Amano P (product name; manufactured by Amano Pharmaceutical Co., Ltd.), Denazym AP (product name; manufactured by Nagase Sangyo Co., Ltd.) ), Neovitalase NP (trade name; manufactured by Towa Koso Co., Ltd.), or Prolysin 5 (trade name; manufactured by Ueda Chemical Industry Co., Ltd.), etc., can be used regardless of the type. The amount of protease added depends on the type of enzyme used, but it is also 0.1 to the treated egg white before dilution.
~1.0% is appropriate. Further, the temperature and time of the protease treatment are suitably in the range of 45 to 55°C for 20 to 50 hours. And finally, add protease treatment solution to 90-100%
The enzyme is inactivated by heat treatment at ℃ for about 5 to 20 minutes, and the egg white decomposition product is obtained. If solid matter is generated by this heat treatment, it may be removed by a decanter method or a centrifugal separation method. In the present invention, as described above, the egg white is diluted to a protein concentration of 3% or less, and the protease treatment is performed in an alkaline range, so there is no need to perform heat denaturation or other treatment before the protease treatment. Hydrolysis progresses well. Therefore, during heat treatment after protease treatment, for example, during heat treatment at 98°C for 10 minutes, almost no heat coagulum is produced, so there is no need to take time to remove heat coagulates as in conventional methods. This step can be omitted. The reason why heated coagulation is difficult to form in this way is that
This is presumed to be because the egg white protein is decomposed uniformly, resulting in less generation of large molecular weight peptites. Furthermore, in the present invention, after the above-mentioned protease treatment, a second protease treatment may be performed to obtain an egg white decomposition product having an even smaller molecular weight. The thus obtained egg white decomposition product is a transparent, tasteless and odorless liquid, but it is easily putrefied when stored at room temperature, so it is preferable to freeze it at -15°C or lower for storage. Note that this egg white decomposition product can be dried into a powder form by spray drying or the like, and in this way, there is no risk of spoilage and it is convenient to handle. Further, the egg white decomposition product obtained by the method of the present invention does not lose its transparency even when heated to 95°C, and is therefore suitable as a raw material for foods, cosmetics, and the like. Furthermore, unlike conventional products, this egg white decomposition product does not have a bitter taste and is tasteless, so it is expected that its range of use will be expanded. The reason why the egg white decomposition product obtained by the method of the present invention does not have a bitter taste is presumed to be because the diluted egg white is treated with protease in an alkaline range, so that it is not evenly hydrolyzed to produce extremely low-molecular-weight peptites. EXAMPLES Hereinafter, the present invention will be specifically explained by showing Test Examples and Examples. <Test Example> Test Example 1 Egg white liquid was treated by an ion exchange method so that the lysozyme content per egg white protein was 1, 2, 3, 4, and 5.
Prepare egg white liquid adjusted to %. After adjusting these egg white solutions to PH7.0 and PH9.0, respectively, they were diluted with distilled water to a protein concentration of 2.4%, and the presence or absence of aggregate formation was observed. The results are shown in Table 1. The temperature of the distilled water used was 25℃.
