2. Description of the Related Art Soybean protein has been widely used for livestock products such as ham and sausage, fish paste products such as kamaboko, and other prepared foods in order to reduce functional costs such as binding property and water retention and reduction of manufacturing cost. Has been done. Among these, the properties required for soybean protein in the production of meat products, particularly ham, are not only the physical properties such as binding property in the final product, water retention property, but also high salt solubility and solution state. It has low viscosity. This is because the ham is generally produced by adding soybean protein to a seasoning liquid (pickle liquid) and injecting the pickle liquid into raw meat. In this case, the viscosity of the pickle solution becomes extremely high with ordinary soybean protein.
Therefore, there is a problem in operability such as a burden on the injector and bubbles in the pickled liquid caused by the high viscosity remaining in the meat, resulting in voids in the final product.

Therefore, a proteolytic product of soybean protein has been recently developed which has been treated with a protease in order to improve the operability to reduce the solution viscosity. However, the enzyme-treated soybean protein has the merit of improving workability due to the decrease in viscosity, but the gel characteristic peculiar to soybean protein is deteriorated,
In particular, in the complex system with a heterologous protein, there are disadvantages that the physical properties and water retention are lowered and the yield of the final product is reduced accordingly.

[0004] In the past, much research has been done on the enzymatic degradation of soybean proteins. For example, in JP-A-51-51552, soy milk obtained from low-denaturation defatted soybean is heat-treated at 90 to 150 ° C. for 10 minutes to 1 second, and microorganisms or enzymes are allowed to act on the soy milk again at 90 to 150 ° C.

After heat treatment of a soybean protein solution, bromelain or papain is allowed to act to form a coagulated state, followed by drying and pulverization. JP-A-62-14796 discloses a vegetable protein derived from Penicillium genus neutral and / or alkaline. Each method of enzymatically degrading with a protease is described. However, the purpose of these is to reduce soybean odor and bitterness due to enzyme treatment, has low viscosity in a solution state, and further has excellent physical properties in a complex system with a heterologous protein such as livestock meat. It is not intended to provide decomposed products.

[Problems to be Solved by the Invention] Generally, the proteolytic product of soybean protein treated with an enzyme has a reduced viscosity in a solution state. Further, the physical properties of these gels are also deteriorated, and along with that, the physical properties of livestock products and the like using soybean protein are deteriorated and water separation is increased. Therefore, the present inventors have an object to provide a soybean protein hydrolyzate which is excellent in salt solubility, has a low viscosity in a solution state, and does not impair the physical properties even when mixed in a meat product or the like.

[Means for Solving the Problems] The inventors of the present invention have made various studies on selection of enzymes to be used and reaction conditions in order to solve the above problems. However, in these studies, treatment with a commercially available protease such as papain as the enzyme to be used did not solve the above-mentioned problems. Therefore, by further selecting and examining the enzyme to be used, if the soybean protein is treated with a certain enzyme, the viscosity in a solution state will be low,
The soybean protein hydrolyzate alone has low gel properties, but the soybean protein hydrolyzate having high gel property in a mixed state with meat and good water retention has been completed, thus completing the present invention. That is, the present invention is a pickle solution having a protein hydrolyzate for a pickle solution obtained by decomposing a soybean protein-containing solution with elastase and a degradable product obtained by decomposing a soybean protein-containing solution with elastase.

In the present invention, the conditions for enzymatically decomposing the soybean protein-containing material with elastase are not particularly limited, but usually the protein concentration is about 5 to 20% by weight, and the enzyme amount is 50 to 1000 as the elastase activity per 1 g of protein.
U and pH are near neutral to alkaline range (about pH 5 to 11), temperature is about 20 to 55 ° C, and reaction time is determined by decomposition rate as described later. In the present invention, it is important that the protein is not completely decomposed into amino acids but is decomposed so that the decomposition rate is 5 to 20%, preferably about 7 to 15%. The degradation rate described here is used as a measure of the degree of protein degradation by proteases, and is the ratio (percentage) of the final concentration of 0.2 M TCA (trichloroacetic acid) soluble nitrogen to the total nitrogen in the protein solution. Say. Next, after the decomposition with elastase, the decomposition liquid may be powdered and dried.

When the protein is decomposed to a level of the above-mentioned decomposition rate using an ordinary protease, the viscosity of the protein solution is reduced, but the gel properties and water retention in the complex system with the heterologous protein are also reduced accordingly. However, by enzymatically decomposing proteins such as soybean protein using elastase as in the present invention, not only can the deterioration of gel properties and water retention in the complex system be prevented, but soybean protein that has not been enzymatically degraded, etc. It is possible to prepare a composite gel superior to that using
Further, since the viscosity in the solution state is reduced, the foam powder stability peculiar to the soybean protein solution is suppressed, and the foam breakage of the protein solution is also improved.

A model ham was prepared using this pickle solution. Model ham is pickled in 10 parts by weight of red pork leg meat
After mixing 7 parts by weight, the mixture was cut and heated at 70 ° C. for 50 minutes to prepare. The gel strength of model ham was measured by the same method as in Example 1. The water retention was expressed as a water separation rate, which is the ratio (percentage) of the amount of water released when a cylindrical sample having a diameter of 30 mm and a height of 5 mm was loaded with 7 kg for 4 minutes to the sample weight. The results are shown in Table 4.

The model ham was also subjected to sensory evaluation. The sensory evaluation was performed by 10 skilled panelists.
The enzyme-untreated product (Sample A) was set to 3 points, and evaluation was performed on a scale of 5 points, and the average thereof was shown. The results are shown in Table 5.

As shown in Table 4, in Samples B, C and D, the pickle solution viscosity was significantly improved, and the defoaming property was also improved. Further, it was shown that the model hams prepared in B and C had higher breaking strength, lower squeezing water separation rate and higher water retention than those in A. Further, as shown in Table 5, the sensory evaluation also showed an excellent value as compared with A. On the other hand, the model ham prepared in D had a lower breaking strength than that in A and was also inferior in sensory evaluation.

Example 3 1 part by weight of the pickle solution prepared in the same manner as in Example 2 was injected into 1 part by weight of the pork arm block with an injector,
Hams were prepared by tumbling overnight at low temperature and then heating with smoke. The sensory evaluation was performed by setting A to 3 as in Example 2,
Evaluation was made on a scale of 5 points and expressed as an average point. The results are shown in Table 6.
