    The process is of the type in which the skimmed milk is heat treated then thickened by standing after the addition of rennet and acid ferments and then centrifuged to separate off the whey. The heat treatment includes holding the treatment temp. of 90 to 95 degrees for an extended period, pref. 2-3 mins. The proportion of rennet to skimmed milk is raised substantially above the conventional level of 1 cc Rennet per 100 L of milk, pref. to about 3 cc per 100 1. The thickened prod. is given a second heat treatment, pref. at 55-60 degrees C. For a holding period of 1-2 mins., after which it is cooled and centrifuged. A pref. final stage comprises mixing into the prod. about 3% of acid ferments. The skimmed milk is supplied by a centrifugal cream separator. The prod. has a smooth, creamy consistency and keeps well. The sepd. whey contains only 5.8-5.85% dry matter compared with a conventional 6.1-5.2%. Higher protein retention produces a 10% increase in the yield of cream cheese.

    (54) METHOD OF GETTING THE CREATURE
    one
    The invention relates to dairy industry, namely to a method for producing cottage cheese from skimmed milk using a separator for separating whey from a milk-protein clot.
    A known method for producing cottage cheese, which involves pasteurizing skim milk, cooling it to the fermentation temperature, fermenting it with the addition of rennet and fermenting lactic acid cultures, heating the clot before cooling, separating, and then cooling the skim O-15
    When working by a known method, part of the whey proteins goes into syrup, which leads to a decrease in the yield of the curd or to the need for 20 subsequent processing of the whey in order to extract proteins from it and deposit them into the original skimmed milk for the subsequent production of curd. In addition, in this case 25
    the process becomes more complex and expensive.
    The purpose of the invention is to increase the yield of the product (without complicating the process).

    To achieve this goal, according to the proposed method for producing cottage cheese, which involves pasteurizing skim milk, cooling to the fermentation temperature, rennet-acid fermentation (with the addition of starter lactic acid cultures and rennet), heating the resulting milk-protein clot to 60 ° C, cooling it, separating and subsequent cooling of the fat-free cottage cheese, the process of pasteurization of milk is carried out by heating to 9095 C with an exposure of 2-3 minutes, the clot heated before separation is kept for 1-2 mi n, and the amount of consumable rennet is 3 cm ° per 100 liters of milk. It is advisable to add the lactic acid starter or fermented cream to the low-fat cottage cheese after cooling. Thus, the proposed method provides for the conditions under which the coagulation of whey proteins and their subsequent addition to casein occur, which improves the conditions for the separation of the milk-protein clot on the separator into whey and cottage cheese and contributes to an increase in the yield of the latter. The drawing shows schematically an installation for implementing the method. The installation includes a heat exchanger equipped with an inlet pipe 1, a pasteurizer 3 connected to it, a pipe 4, a connecting heat exchanger 2 with a container 5 for fermentation, a pump 7, a pipe S, a heater 9, a pasteurizer 10, a pipe 11, which binds the pasteurizer 10 to a centrifuge 12, in which the separation of the milk-protein clot into curd and whey, pipeline 13 for removal of whey, pipeline 14 for feeding curd to refrigerator I5, pipeline 16 for adding curd or fermented cream yeast, CME Sitel July 1 and a conduit for 1.8 4hodachi naupakovku product. The proposed method is carried out as follows. The skimmed milk in the heat exchanger 2 is heated to 9095 ° C and kept at this temperature for min. Then the milk is cooled to 28-30 ° C in the regeneration section of the apparatus 2 and through the pipeline 4 enters the fermentation tank 5. It is also served with lactic acid ferment and rennet. The amount of the starter is, for example, 0.5% by weight of the milk. The amount of rennet is determined at the rate of 3 cm per 100 liters of milk (enzyme concentration 1: 10,000). After 16 hours, a clot forms, its pH is 4.5. The clot is fed through conduit 8 by means of a pump 7 to the preheater 9, where it is heated up and held for 1-2 minutes. After heating, the clot cools before and through line I1 goes to centrifuge 12. The latter separates it into curd and whey, which is discharged through line 13 for subsequent 604 use. The curd is fed through line 14 into cooler 15, cooled to 6-8 seconds, after which 3.0% ferment or sour cream is supplied to it (through line 16), everything is mixed in mixer 17. The finished product is directed through line 18 to packaging. The resulting cheese has a creamy consistency. The whey formed during the production of curd contains 5.8-5.85% of dry substances (in the whey obtained during the production of curd according to a known method, the content of dry substances is 6.1-6.2%). The yield of curd is increased by about 10% or the consumption of skimmed milk is reduced by 0.5 liters per kilogram of curd. Example. Skimmed milk in the amount of 10,000 liters is heated to 92s and kept for 3 minutes at this temperature. The milk is then cooled to 27 ° C and 50 l (0.5%) of the lactic acid bacteria type M. S K / O ,, are introduced into it, representing a thermotrophic multi-strain culture consisting of 60% Lbm.acidophilum 74 and 40% bifidumbacterium 1, as well as 300 cm of a liquid syuzhny enzyme, with a concentration of 1: 10,000. After 17 hours, the pH is 4.5. The petty-protein clot formed is heated on a heat exchanger until and kept for 2 minutes. The clot is then cooled to 40 ° C and fed to a Westfali KD A 30 separator for separation into curd and whey. The resulting whey contains 5.75% solids. The content of solids in the curd is 17.5%. The amount of cottage cheese is 2515 kg. (In the implementation of this example by a known method, the amount of obtained cottage cheese is 2283 kg). Claim 1. Method for producing curd, which involves pasteurizing skimmed milk, cooling to fermentation temperature, fermentation with the addition of rennet and fermenting lactic acid cultures, heating the clot before cooling it, separating and then cooling the resulting fat-free 589096 curd, so that that, for the purpose of producing a product, pasteurization of skim milk is carried out at EO-EZ C with an exposure of 2-3 minutes, the heated clot is kept for 1-2 minutes, and the amount of consumable A rennet enzyme is 3 cm 100 ml of milk.
