2. Description of the Related Art Fresh cheeses such as quark and cottage cheese sterilize raw milk, add a lactic acid bacterium starter, and coagulate casein with lactic acid produced by the action of the added lactic acid bacteria to form curds and eliminate whey. It is prepared by adding acid directly to milk and curdling. These quark and cottage cheeses differ in the method of whey elimination in the manufacturing process, but the final products differ only slightly in terms of texture and flavor. These quark and cottage cheeses are generally referred to as fresh cheeses, including unripened cheeses, which obtain curd by an acid coagulation method. In the present invention, fresh cheeses including unripened cheeses produced by a lactic acid fermentation method such as quark and cottage cheese are also referred to. Fresh cheese has a structure and flavor that are favored by many people, but cannot be stored for a long time while maintaining its quality. Because fresh cheese has a relatively high water content and causes water separation during storage, it rots due to microbial contamination,
Lactic acid can be used to produce lactic acid from lactose,
It is said that acidity and off-flavor are generated, and storage for 2-3 weeks is limited even if refrigerated. Therefore,
At present, preservatives are used to suppress the growth of microorganisms in order to enhance the preservability of fresh cheese, but it is difficult to completely prevent spoilage and tissue deterioration. In addition, in order to prevent spoilage during storage, attempts have been made to heat sterilize, but the heating causes aggregation of the card particles, deteriorating the structure of the card, and cannot maintain an edible tissue. is the current situation.

[0003] Fresh cheese contains calcium,
Domestic consumption of high-protein, low-fat food is growing steadily. However, it is said that the production of milk materials such as raw milk, skim milk, skim milk powder, and whole milk powder, which are the main raw materials of fresh cheese, cannot keep up with the increase in consumption and is in an urgent situation at present. Therefore, acid casein, rennet casein, whey protein (whey protein concentrate, whey protein isolate) are used as substitutes for these milk ingredients.
Attempts have been made to produce fresh cheese using the same method, but acid casein and rennet casein have poor solubility, and whey protein has difficulty in forming curd. Therefore, these dairy ingredients were sometimes added as a part of the raw material milk as a solid content extender, but it was difficult to use them as a main raw material instead of the raw material milk.

Under such circumstances, in the production of fresh cheese, it is first required to obtain a fresh cheese having a good texture and flavor, in which a decrease in pH and water separation during storage are suppressed. Second, it is required to produce fresh cheese by using a substitute for milk materials such as raw milk, skim milk, skim milk powder, and whole milk powder. Accordingly, an object of the present invention is to provide a fresh cheese having good preservability, texture and flavor using a milk material other than the above-mentioned milk material, and a method for producing the same.

[0007] MPC prepared as described above contains a high concentration of protein and has very low lactose and mineral contents. Therefore, when MPC is used as raw milk for producing fresh cheese, the protein content of non-fat milk solids (milk-derived proteins, lactose, and minerals) in cheese can be increased. On the other hand, since the lactose and mineral contents are low, these lactose and minerals are appropriately added according to the target product. The lactose content in the raw milk is a factor that affects the time required for curd formation and the amount of whey discharged from the curd, as well as the shelf life of the obtained fresh cheese. Since the amount can be appropriately adjusted, the conventional problems in the production of fresh cheese, such as improvement in the preservability of fresh cheese, can be solved. As noted earlier, MPC
It usually contains about 80% protein, about 5% lactose and about 7.5% minerals. Therefore, when the raw milk is prepared using MPC as a main raw material, the content of minerals and lactose is lower than that of the raw milk usually used when preparing fresh cheese. In particular, when the lactose content is low, it takes a long time to form the curd or the curd may not be formed. Therefore, lactose is appropriately added as needed. In order to obtain fresh cheese having good shelf life without affecting curd formation or whey exclusion, raw milk prepared using MPC as a main raw material may contain lactose in an amount of 2.4 to 4.5% by weight. .

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, as fresh cheese,
The present invention will be described by exemplifying quark and cottage cheese. According to the present invention, lactose is added to milk prepared using MPC as a raw material milk, and quark and cottage cheese can be produced according to a conventional method. Both quark and cottage cheese have the same method of preparing raw milk. When the MPC is a powder, 3.8 to 20% by weight of the powder
(3-20% of protein, 0.15-1.0% of lactose) is dispersed and dissolved in water and homogenized to prepare a raw milk. Next, lactose is added to the MPC solution. As described above, lactose is preferably added in an amount of 2.4 to 4.5% by weight in the raw material milk. In addition, this value is a value of 50-95% with respect to the lactose content (4.7%) of skim milk normally used for manufacture of fresh cheese.
In particular, lactose may be contained at 50-70% in consideration of curd formation, whey elimination, storage stability and the like. In the present invention, in addition to the MPC powder, a solution of MPC, that is, a retentate or a concentrated solution can also be used. When these are used, it is also preferable that lactose be contained in the above-mentioned range.

Test Example 1 The quark and cottage cheese obtained in Examples 1 and 2 were measured for pH and water separation immediately after production and after storage for 4 weeks, and subjected to sensory evaluation. The pH was measured by adding 40 g of water to 12 g of each cheese and using a homogenizer (AM-11, AM-11).
(Nippon Seiki Seisakusho Co., Ltd.), pulverized at 10,000 rpm, and then filtered. The pH of the filtrate was measured with a pH meter (F16,
(Manufactured by Horiba, Ltd.). The water separation rate was measured by opening the lid of a container containing 90 g of cottage cheese, tilting it at 90 degrees for 30 seconds, measuring the amount of water discharged, and showing the amount as a percentage of the weight of the original cottage cheese. Table 3 shows the above results.
