One example is Fuji Oil Co., Ltd.'s low sugar vegetable protein trade name “New Fuji Pro-SH”, which is a defatted soybean extracted with water and separated into a water-insoluble fraction and a water-soluble fraction. The water-insoluble fraction and the water-soluble fraction are separated by isoelectric focusing, and the water-insoluble fraction is washed with warm water to 1 times.
It is obtained by a method of neutralizing by repeating once or twice or more.

That is, plant proteins such as soybean protein are effective for removing odors and soft texture. However, among the plant proteins, a high-sugar plant protein containing a large amount of saccharide component is exposed to high temperature in the extruder and a large amount of saccharide component is thermally decomposed and discolored. Therefore, even if the white seafood is beautiful, it is not possible to obtain excellent whiteness. Also,
If the added amount is less than 0.5%, sufficient effects cannot be obtained because the odor is removed and the texture is cured. If it exceeds 20%, even if the amount of saccharides is low, the amount of saccharides increases and the color changes during heating, which is not preferable.

As a result of the above comparison, in terms of texture, the one to which the plant protein was added had an extremely excellent texture compared to other starch and the one to which egg white was added, regardless of the content of sugars in the plant protein. I was able to hold it.

Next, looking at the odor, egg white has a bad odor due to thermal decomposition, and has a poor flavor even after it is made into a product. On the other hand, a starch or a protein with high sugar produced a bad odor due to thermal decomposition during the biaxial extruder treatment, but after the product was made, the bad odor did not remain and the flavor was tentatively good. On the other hand, in Example 1 in which the low sugar protein was added, there was no bad odor during the biaxial extruder treatment, and the flavor was good even when the product was obtained.

Next, each filament was taken out from each product and was pulled to determine the cutting strength. Of these, Comparative Example 2 had 620 kg / mm 2 because egg white was added.
The strength of the starch was 350 kg / mm 2 in the case of starch.
In Example 1 and Comparative Example 3 in which the plant protein was blended, the cutting strength was higher than that.

Further, comparing Comparative Example 3 with Example 1, the cutting strength is higher than that of Comparative Example 3 because the sugar content of Example 1 is low.

In addition, since the meat portion of seafood consists of whiteness, the color tone was determined as Hunter whiteness, and the degree of discoloration during the biaxial extruder treatment was determined. That is, the whiteness of Comparative Examples 1 and 2 in which starch and egg white are mixed is increased. But,
Despite being a plant protein that is blended in Example 1, the blended plant protein contains only 0.4 or less sugar. Therefore, the whiteness of Example 1 is 7
This value was 8.8, which was close to that of Comparative Example 2 containing egg white, and the whiteness was the highest.

Example 3. Exposing the edible portion of Itoyori to water as in Example 1 and dehydrating it.
To this, 5 parts by weight of sorbit (0.2 parts by weight of phosphate) was added, and the mixture was kneaded and crushed to prepare a ground meat and frozen. After thawing the frozen surimi, 0.5 parts by weight of salt, 1 part of starch and 3 parts of low sugar vegetable protein (the same as in Example 1) were added to the surimi and kneaded well with a silent cutter to prepare a sol.
