2. Description of the Related Art Cheese contains various nutrients such as proteins, lipids, calcium, vitamins and minerals in a well-balanced manner, and is particularly noted as a high-quality calcium source, and its demand is increasing year by year. Among them, in particular, cheese that exhibits cooking characteristics by heating, for example, a process cheese of a type that exhibits stringiness by heating, and conversely, a type that maintains shape retention without melting even when heated. Many processed cheeses have been developed. In addition, fresh cheese and other cheeses that have no habit and are fresh are suitable for Japanese tastes, and the demand for such cheese is expected to increase in the future.

It is known that it is effective to use cheese with low maturity to impart cooking characteristics, especially heat-resistant shape retention to cheese. Attempts have also been made to prepare process cheese by increasing the amount of cheese blended. However, if the amount of low-ripeness cheese is large in the conventional method, the texture of the obtained processed cheese is often hard and brittle, which is not preferable. Therefore, in order to improve the texture in the processed cheese prepared using low ripeness cheese,
Stabilizers such as carbohydrates or polysaccharides have also been added, but this may lead to problems such as tissue embrittlement or flavor deterioration during storage.
In addition, water is added during emulsification to increase the water content of the processed cheese, but this has the problem that the flavor deteriorates during storage and water separation occurs.

On the other hand, when manufacturing process cheese,
When ripened cheese is used as a raw material cheese and heated and emulsified at a normal temperature (for example, 80 to 95 ° C.), the resulting cheese has a rich flavor, which is preferable for applications requiring rich flavor. However, it lacked flat flavor and freshness. Therefore, if low-ripening cheese is used as the raw material cheese in order to obtain a flat flavor and a fresh feeling, a flat flavor and a fresh feeling can be obtained, but it has a gum-like texture.

By making a low-ripe cheese of 5% or less a raw cheese, adding a molten salt to the raw cheese, and emulsifying by heating at a temperature of 110 ° C. or more, the processed cheese obtained has a smooth texture. This is presumably because the casein structure was changed to an unusual form by increasing the emulsification temperature, and a new casein soluble aggregate was formed. In addition, Japanese Patent Publication No. Sho 61-22932 discloses a method in which a molten salt is added to raw material cheese, sterilized by heating and melting at a temperature of 120 ° C. or higher,
A technique relating to a pasteurized process cheese obtained by cooling to ℃ 100 ° C. and adding a tissue forming agent is disclosed. This technique disperses a tissue improving agent made of casein to form a normal spread-like cheese. The purpose is to obtain a processed cheese having a texture, and the properties of the sterilized processed cheese disclosed in this publication are different from those of the processed cheese of the present invention.

[0017] STN /
The TN value will be described. The form of nitrogen in natural cheese varies according to the degree of ripening of the cheese, and in particular, the soluble nitrogen (STN) tends to increase as the ripening of the cheese progresses. The ripeness (%) = STN / TN value represented by the ratio of the soluble nitrogen to the total nitrogen (TN) is generally used as an index indicating the degree of ripening of the cheese. The larger this value is, the more mature the cheese is Indicates that In the present invention, the raw material cheese has a ripeness (STN / TN value) of 15%
By using the following cheese, a fresh flavor without habit and good heat resistance can be imparted to the obtained processed cheese.

Ripeness (STN / TN value) (%) = (soluble nitrogen / total nitrogen) × 100 The measurement of total nitrogen and soluble nitrogen is performed by the following method. First, 10 g of raw material cheese was collected, and 40 ml of 0.5N sodium citrate aqueous solution and 40 ml of distilled water were added thereto,
After grinding for 5 minutes with a homoblender, transfer to a volumetric flask, add distilled water to make the volume to 200 ml, and use it as a sample solution. Next, 10 ml of the sample solution is collected, and total nitrogen (TN) is measured by the Kjeldahl method. Furthermore, 1.4 ml was added to 10 ml of the sample solution.
After adding 10 ml of 1N hydrochloric acid, the volume was adjusted to 125 ml with distilled water, and the resulting protein precipitate was filtered.
1 is collected and soluble nitrogen (STN) is measured by the Kjeldahl method. Thus, the maturity of the raw material cheese used in the present invention can be measured.

In the present invention, as the molten salt added for the purpose of improving emulsification during heating, any molten salt may be used as long as it is a commonly used molten salt for producing processed cheese. Sodium acid, sodium monophosphate, sodium diphosphate, sodium polyphosphate and the like can be mentioned, and two or more of these can be used in combination. The addition rate of the molten salt is preferably 0.5 to 5% by weight based on the raw material cheese. If the addition ratio is less than 0.5% by weight, emulsification during emulsification becomes insufficient,
The texture of the obtained processed cheese may also be non-uniform, which is not preferable. If the addition ratio exceeds 5% by weight, casein agglomerates, and the texture of the obtained processed cheese may be rough and the flavor may be deteriorated. Absent.

In the heating emulsification, kneading is performed while heating at 110 ° C. or higher for about 1 minute using an emulsifier. Temperature during emulsification is 1
If the temperature is lower than 10 ° C., the texture of the obtained processed cheese is hard and brittle, which is not preferable. As the emulsifier that can be used at the time of emulsification, any emulsifier may be used as long as it is an emulsifier usually used for the production of process cheese, for example, performing both direct steam heating and indirect heating. Examples include scrapable heat exchangers, feeders, extruders, and combinators. The upper limit of the heating emulsification temperature is an upper limit within a range in which the characteristics of the processed cheese intended by the present invention can be obtained, and is, for example, about 150 ° C. If heat emulsification is carried out at a temperature exceeding 150 ° C., in some cases, casein will be excessively denatured and agglomerated or browning will occur. Therefore, heat emulsification at a temperature up to about 150 ° C. is preferable.

For 10 g of each processed cheese, 40 g of distilled water was added.
g, and the suspension was stirred at 10,000 rpm for 10 minutes using a homogenizer. This suspension was centrifuged at 10,000 rpm for 20 minutes at 4 ° C. using a Beckman high-speed centrifuge to separate fat, supernatant and sediment. this house,
The protein in the supernatant was quantified to determine the amount of soluble protein.

Further, a 4-fold amount of distilled water was added to the supernatant, and the mixture was filtered through a 0.45 μm filter, and the protein in the filtrate was subjected to molecular weight fractionation by gel chromatography. The gel chromatography conditions were as follows: two columns of SB806HQ and SB806MHQ (both manufactured by Showa Denko) were connected in series, and a buffer containing 70 mM potassium chloride and 10 mM imidazole hydrochloride (pH 7.0) was used.
Using 1), apply 50 μl of the filtrate at a flow rate of 0.5 ml / mi.
Flowed through the column at n. Then, the protein fractionated by the column was quantitatively determined by measuring the absorbance at a UV wavelength of 280 nm over time to calculate the molecular weight distribution of the soluble protein.

According to the present invention, it is possible to provide a processed cheese having a fresh flavor without habit, having good heat resistance, and having a smooth texture. Conventionally, when processing cheese is prepared using low-ripening cheese (ripening 15% or less) as a raw material cheese, the resulting processed cheese has a hard, brittle, gum-like texture and a favorable flavor. Although not produced, the processed cheese produced by the method of the present invention has a smooth texture, has a good melting property in the mouth, and has a fresh taste without habit, so it is preferable to eat it as it is, and it is also used for salads and the like. May be. further,
Since it has heat resistance, it can be used for topping of gratin and the like.
