Abstract

PURPOSE:To obtain the title composition of good formability with both flavor and taste peculiar to albumen without the need for any additive by removing part or the whole of lysozyme from albumen to bring the pH value to that of raw albumen. CONSTITUTION:0.03-0.05vol.% of a cation exchange rein with alcoholic hydroxyl group localized is added to albumen pref. homogenized in advance, and the albumen is kept at 5-10 deg.C, being treated for 2-5hrs while stirring to effect adsorption of >=0.3wt.% of the lysozyme (ca. 0.5wt.% of lysozyme is contained in albumen) on the cation exchange resin. Thence, said cation exchange resin is separated from the above albumen, thus obtaining the objective albumen composition of good formability. This composition is 8.0-10.0 in pH, same as that for raw albumen, and the content of lysozyme in the composition will become 0-0.2wt.%. Said cation exchange resin is such one with, as intramolecular cation exchange group, alcoholic hydroxyl group such as sulfonic or carboxylic group localized.

However, although the above-mentioned conventional egg white compositions have improved foaming properties, they not only require the use of expensive additives, but also lose the original flavor and taste of egg whites due to the use of additives. It tends to be easy.

The object of the present invention is to provide an egg white composition with good foaming properties and a method for producing the same without using any additives.

The egg white composition with good foaming properties of the present invention has the same pH as egg white, and is characterized by having all or a portion of lysozyme D removed from the egg white. This method is characterized in that the S@ ion exchange resin in which the hydroxyl groups are localized is completely added, the lysozyme in the egg white is adsorbed to this resin, and then this resin is separated from the egg white.

In the present invention, the same pH as raw egg white means that the egg white composition is in the same alkaline range as normal egg white, and preferably, the pH is within the range of 8.0 to 10.0. .

In order to obtain the egg white composition with good foaming properties of the present invention, raw material egg white and a cation exchange resin are first prepared.

As the egg white, in addition to raw egg white obtained by cracking shelled eggs and separating the yolk, egg white obtained by thawing frozen egg white, etc. can be used. It should be noted that commercially available dried egg whites are undesirable because the pH of the egg whites is adjusted to an acidic range during pretreatment, and the proteins are denatured during the drying process, resulting in decreased foaming properties.

As a cation exchange resin, cation exchange groups in the molecule of the ion exchange resin include sulfone group, carboxyl group,
A resin in which alcoholic hydroxyl groups such as trimethoxy groups are localized is used.

Even if the cation exchange resin has an alcoholic hydroxyl group, resins with natural polysaccharide skeletons, such as ion exchange cellulose, ion exchange agarose, and ion exchange Sephadex, will not react well when the egg white is in the alkaline range. It is undesirable because it has a weak affinity with lysozyme and has a low adsorption power for lysozyme.

Next, a cation exchange resin is added to the egg white, and the lysozyme in the egg white is adsorbed to this resin.

In order to improve this adsorption efficiency, it is desirable to homogenize one raw material, egg white, in advance.

The amount of cation exchange resin added to egg white depends on the type of resin used, but it is 0.03 to 0.05 parts (
Capacity part) is good. Moreover, as conditions for adsorption, it is appropriate to maintain the temperature of the egg white at 5 to 10° C. and treat it for 2 to 5 hours while stirring.

In this adsorption process, 0.0% of lysozyme in egg white (egg white contains about 0.5% by weight of lysozyme).
It is desirable that at least 50% by weight of the cation exchange resin be adsorbed onto the cation exchange resin. If the removal rate of lysozyme in egg white is too low,
This is because the foaming properties of egg white tend to be difficult to improve.

Next, by separating the cation exchange resin from the egg white, the desired egg white composition with good foaming properties can be obtained. A filter or a centrifuge may be used to separate the cation exchange resin.

As will be shown in later test examples, this egg white composition has superior foaming properties to raw egg white, and its pH is slightly alkaline, so it has the advantage of being difficult for microorganisms to propagate.

As another method for removing lysozyme from egg white, for example, as proposed in Japanese Patent Publication No. 51-38791, raw egg white is treated with a weakly acidic ion exchange resin and lysozyme in the egg white is adsorbed by the resin. There is also a method of removing this resin from the egg whites after this process, but according to this method, the egg whites are treated with a weakly acidic ion exchange resin, so the P of the resulting egg whites is reduced.
H is in the acidic range 0 Therefore, in order to give this egg white composition foaming properties, an alkaline agent is added to the egg white to adjust the pH of the egg white to an alkaline range (PH8.0 to 10.0). do it. However, although the egg white composition obtained by this method has foaming properties, the taste is different from that of raw egg white, so it is preferable to manufacture the egg white composition of the present invention by a method that does not adjust the pH of the egg white. .

Another possible method is to add a large amount of neutral salt such as table salt to egg whites, crystallize and remove lysozyme, and then desalt the egg whites to obtain egg whites from which part or all of the lysozyme has been removed. According to this method, the egg white protein is denatured by the added neutral salt and the egg white protein loses its foaming properties, making it impossible to obtain the desired egg white composition.

Although we have not investigated in depth the principle by which the foaming properties of the egg white composition of the present invention are improved, we have determined that the pH of the egg white composition is the same as that of raw egg white, and that the lysozyme in the egg white is It is speculated that by removing all or part of the egg white protein, opomucin, which is the main protein component of egg white, is released from the restraints of lysozyme and becomes activated, and this ovomucin changes the egg white composition into a property that makes it easier to foam.
