Both quark and cottage cheese have good texture and flavor, but cannot be stored for a long time while maintaining their quality. This is because water is released during storage and rot is caused by microbial contamination. Therefore, even if it is refrigerated, it is said that the maximum storage is 2-3 weeks. In order to improve the shelf life of these fresh cheeses, at present, a method of suppressing the growth of microorganisms by using a preservative and a method of freezing are performed. However, even with these methods, it is difficult to completely prevent spoilage and tissue deterioration, and operability is poor, so that the range of use has been narrowed. In addition, when heat sterilization treatment generally used in foods is performed to try to prevent spoilage during storage, the curd particles of fresh cheese agglomerate, so that an edible structure cannot be maintained.

In order to solve such a problem, high methoxyl pectin having an esterification degree of 74 or more is used, as in Japanese Patent Publication No. 1-42656 "Production Method of Raw Cheese-like Food with Good Preservation".
A method is disclosed in which 0.02 to 2.0% is added, the mixture is sterilized by heating at 70 ° C. or higher with stirring, and further acid-treated gelatin or lecithin is added if necessary. In this method, high methoxyl pectin having a degree of esterification above a certain level is added and sterilized while stirring without any treatment, and a special device called a scraping heat exchanger such as an onrator is used. ..

In this method, since the raw cheese is used as it is, the viscosity of the raw cheese is so high that it cannot be processed by a general apparatus. Therefore, a special device called a scraping heat exchanger is required. Further, when using such an apparatus, it is possible to simply stir and mix, and improve the heat transfer property for heat sterilization, but high methoxyl pectin cannot sufficiently act on curd particles of raw cheese. .. Therefore, the curd particles of raw cheese cannot be sufficiently protected against heat sterilization, which leads to deterioration of the tissue, so that heating for a long time cannot be performed. In addition, the obtained product has a paste-like structure, and is different in flavor from the original structure and flavor of fresh cheese such as quark or cottage cheese.

Since fresh cheese has a higher solid content than fermented milk, it has a viscosity of 100 poise or more at a low temperature of 10 ° C., a high viscosity and no fluidity. Therefore, in order to process fresh cheese as a raw material, it is necessary to use a special device capable of processing a highly viscous material. In the present invention, first, fresh cheese is liquefied. To liquefy, the temperature immediately after the curd production, that is, the fresh cheese production, is 40 ℃.
When the curd is in front of or behind, the curd is stirred as it is, or when the curd is cooled, the curd is heated to a range that does not cause heat denaturation, and the fresh cheese is stirred. As a result, a low-viscosity liquid having fluidity is obtained. The low-viscosity liquefied fresh cheese can be processed by a normal device without using a special device for high-viscosity substances.

What is important in this treatment step is that the curd is treated while being heated to a temperature at which it does not undergo heat denaturation, and sufficient fluidity cannot be obtained without heating. Furthermore, fresh cheese curd particles, when using high methoxyl pectin at a pH within a certain range,
Aggregation due to heating is unlikely to occur, and therefore tissue deterioration is unlikely to occur. Furthermore, when the mixture is homogenized with a homogenizer before heat sterilization, a fresh cheese extremely stable against heat sterilization can be obtained.

Specifically, fresh cheese such as quark and cottage cheese is heated up to just before the curd undergoes heat denaturation. The temperature is limited to 60 ° C, preferably 30 to 50 ° C. Stirring while performing this treatment, a liquefied fresh cheese having a viscosity of 50 poise or less at 40 ° C. is obtained. This is to improve the workability and operability to be performed thereafter and to improve the heating stability, and cannot be excluded from these series of operations. If liquefaction is attempted at low temperature without heating, it cannot be processed because of its high viscosity and lack of fluidity. Further, when the viscosity exceeds 50 poise when heated to 40 ° C., it cannot be processed by an ordinary apparatus. Further, if heating at more than 60 ° C. is attempted to liquefy, curd particles are aggregated, which is not preferable.

Next, high methoxyl pectin as a stabilizer is added to the liquefied fresh cheese and mixed.
The mixture is adjusted to pH 3.5-4.6 with acid. More preferably, high methoxyl pectin is dispersed and dissolved in water and added to fresh cheese to form a mixture, pH 4.0 to pH.
Adjust within the range of 4.4. Below this range, the sourness is strong and the flavor is bad, and above this range, precipitation and separation occur, which is not preferable as a product. The operation of heating and liquefying may be performed after adding a stabilizer. The pH-adjusted mixture is then homogenized. The homogeneous condition is, for example, 50 to 150 kg / cm 2 , but the pressure does not matter. Moreover, a normal homogenizer is used. This is because the high methoxyl pectin sufficiently acts on and stabilizes the curd particles of fresh cheese in this mixture. Therefore, a high-pressure homogenizer consisting of a high-pressure pump equipped with a homogenizing valve, that is, a so-called homogenizer is suitable for the apparatus used for the homogenizing treatment.

When a device such as a simple stirrer or a scraping heat exchanger is used, the high methoxyl pectin cannot sufficiently act on the curd particles of fresh cheese. Therefore, stabilization against heat sterilization cannot be imparted, and finally a good product cannot be obtained. In addition, heating for a long time is not desirable because it causes deterioration of the tissue. The product obtained by such an apparatus has a paste-like structure, and also has a flavor different from the original structure and flavor of fresh cheese such as quark or cottage cheese.

In this way, the homogenizing treatment is carried out, and then the sterilization treatment is carried out. It is easier to use a sterilizer in which a homogenizer and a sterilizer are linked. If necessary, milk components, sugars, stabilizers, water, acidulants, flavors and the like may be added to and mixed with the fresh cheese before homogenization / sterilization or after sterilization. When preparing desserts and beverages using sterilized fresh cheese as a raw material, stabilizers such as gelatin, agar, starch, guar gum, locust bean gum, and low methoxyl pectin can be added if necessary. Finally, when heat sterilization is performed, the pH may change due to the influence of the raw materials other than the sterilized fresh cheese used, but the pH should be adjusted again within the range of 3.5 to 4.6 and homogenized. And then heat sterilization. The heat sterilization is not particularly limited as long as it is a method that can eliminate the influence of microorganisms and enzymes that deteriorate the preservability.
