<Industrial Application Field> The present invention relates to foods, and relates to the production of industrially advantageous yogurt products. In this case, yogurt refers to soft type, hard type, plain type, drink type, pulp/juice mixed type, and frozen type. <Prior art> Taking hard type yogurt as an example, the general manufacturing process is as follows. The raw materials include at least 8% skim milk powder, sugar, and other stabilizers such as agar, gelatin, and carrageenan. First, these materials are mixed into warm water. Then, during a series of operations of homogenization (150 to 200 Kg/cm 2 ), sterilization (90 to 95°C, 10 minutes), and cooling (42 to 45°C), lactic acid bacteria and the like are added as a starter and fermentation is carried out. Fill containers when the starter is added, stop fermentation at pH 3.8, and refrigerate.
The purpose of adding stabilizers in the formulation is to reduce syneresis of yogurt and give it appropriate elasticity, hardness, and texture. However, conventional stabilizers such as agar, gelatin, and carrageenan have the following drawbacks. These stabilizers have a high gelation initiation temperature, and depending on the amount added, it is necessary to take measures to prevent gelation, such as constant stirring during the cooling process. These stabilizers combine with yogurt to inhibit the release of yogurt's unique and desirable flavors. The texture of yogurt made with these stabilizers has the following drawbacks: Gelatin has wet viscoelasticity, but softens at room temperature and has a rough texture. Although agar has hardness, it is a fragile tissue. It has a strong reactivity with carrageenan protein, and it separates under low pH conditions, causing tissue roughness. The above-mentioned stabilizers have been used singly or in combination, but they are by no means satisfactory. <Problems to be Solved by the Invention> Here, a whey protein concentrate (hereinafter referred to as WPC) that does not have thermocoagulability is employed. WPC is a byproduct of producing cheese and casein. There is an industrially established method in which whey is pulverized through the steps of ultrafiltration, concentration, and drying. It is used as a substitute for egg white because it is soluble in water and exhibits properties similar to egg white, such as thermal coagulation when heated. One possible way to eliminate the thermal coagulability of WPC is to denature the protein in the WPC component with temperature, pH, etc., but in most cases, this will result in a decrease in solubility in water, an increase in viscosity, and a decrease in milk viscosity. It causes off-taste and off-odor other than sweet flavor and cannot be used in practice. <Means to solve the problem> Here, by adjusting the ultrafiltration membrane, the conventional
Similar to WPC, it is possible to obtain WPC that is protein-undenatured but not thermocoagulable. The ultrafiltration membrane used here has a molecular weight cut-off of 20,000~
It refers to 100,000 semi-permeable membranes. The WPC obtained in this way differs from conventional WPC only in the presence or absence of thermal coagulation, and is soluble in water,
There is no difference in flavor, total protein content, etc. The amount used is 15% of the total amount of yogurt.
% or less (weight %), preferably 1 to 8%.
It has the following effects and advantages: It gives yogurt an appropriate hardness, and the hardness can be freely adjusted by changing the amount added. Yogurt texture is extremely smooth. It is preferable because it exhibits a characteristic texture that is clearly different from other stabilizers. The amount of water separation decreases. Workability is good because no gelation occurs due to cooling or thermal coagulation occurs even when heated at high temperatures such as plate sterilization. The effects of this invention will be explained below. Experimental example 1 ◎ Syneresis test (plain type yogurt) Add each sample while heating city milk.
(Samples and amounts added are described separately) Milk temperature is 80℃
Homogenized (150Kg/cm 2 ), then sterilized (90-95℃,
10 minutes) and cooled (40℃). Lactic acid bacteria yogurt (containing at least 10 7 lactic acid bacteria/g) is added as a starter at 3% (wt%) of the total amount and fermented at 40°C. Stop fermentation at pH 3.8 and refrigerate the yogurt. The syneresis rate of this finished yogurt was examined. (Judgment method) Pour a certain amount of yogurt from each sample into a fine-mesh strainer. Cut each sample in the same way with a knife (about 1 cm square). At this time, the amount of water flowing out for 5 minutes was measured to determine the water separation rate. Water separation rate (%) = Amount of water separation from yogurt in 5 minutes (g) / Total weight of initial yogurt (
g)×100

This is made from yogurt as a base, and 65% yogurt base is mixed with 35% fruit syrup, and 0.5% WPC, which does not coagulate under heat, is added. This was frozen in an ice cream freezer, with an overrun of 70%, and cured at -25°C. The frozen yogurt thus produced had a very smooth texture and a good flavor.
