Three, summary of the invention
The object of this invention is to provide a kind of processing method of pizza cheese, the processing method of this pizza cheese is for solving the problem that the processing cycle is long, production cost is high of current pizza cheese.
The technical solution used in the present invention is: the processing method of this pizza cheese is as follows:
One, preparation curdled milk,
Raw material fresh cow milk is obtained to curdled milk through pretreatment;
Two, curd cutting:
By the curdled milk in step 1, use special cutter cuts into the little cubic block of the 1cm length of side, then static 5min;
Three, intensification blanching:
Curdled milk in step 2, in cheese vat, is used intermediate water in 30min, to be slowly heated to 40-43 DEG C, and constantly stirred;
Four, discharging whey:
Ziega after treatment step 3 and whey mixture are stirred to 40-80min 40-43 DEG C time, when the titratable acidity of whey is 16-20
owhole wheys of draining when T, and collect ziega;
Five, heap is made matter structure:
The grumeleuse that step 4 is collected is incubated 40-42 DEG C in curd vat, and every 10min overturn once, and the titratable acidity of mensuration whey is 45-55
owhen T, finish this step;
Six, pulverize and mix dry salt:
Grumeleuse after treatment step 5 is pulverized, and temperature drops to 20-25 DEG C, admixes the salt of the 2-3% of grumeleuse weight, static 10-15min;
Seven, heat is boiled stretching:
By grumeleuse after treatment step 6, boiling 10-20min in the saliferous hot water that is 3-4% at percentage by weight, then the taking-up of grumeleuse draining being positioned over to heat boils in stretching-machine, add the salt of grumeleuse weight 0.2-0.8%, add the SPE of grumeleuse weight 0.2-1.2%, the green starch of grumeleuse weight 0.2-1.0%, the aluminum phosphate sodium of grumeleuse weight 1.5-3.0% simultaneously, and to keep temperature be at 70-80 DEG C, rub up stretching 20-50min;
Eight, cooling forming, obtains pizza cheese:
Pizza cheese after treatment step 7 is taken out while hot and is positioned in cheese mould, and precompressed 2-10min moulding on cheese squeezer, is then cooled to rapidly 4-10 DEG C, obtain stay in grade without the maturity period, without soaking the pizza cheese of salt solution.
Pizza cheese vacuum packaging refrigeration in such scheme is commercially available product.
The process of preparing curdled milk in such scheme is as follows:
(1) raw milk is filtered:
Raw material fresh cow milk, through 200 order filter-cloth filtering 1 time, is placed in process of cheese making groove;
(2) standardization:
Adopt and add low form skimmed milk powder mode and carry out standardization, step (1) Raw is heated to 40-50 DEG C, add appropriate low form skimmed milk powder, adjusting protein in raw milk is 1.42:1 with fatty ratio, and then temperature keeps stirring 5-10 minute;
(3) pasteurize:
Raw milk in step (2) is heated to 63.5 DEG C in water-bath cheese vat, between the period of heating, constantly stirs then static insulation 30min;
(4) cooling:
By the raw milk after step (3) sterilization processing, be cooled to rapidly 15-20 DEG C;
(5) pre-acidifying:
In raw milk after step (4) cooling processing, add the lactic acid solution of percentage by weight 20%, and constantly stir, the titratable acidity of adjusting raw milk is 21-24
ot, then continues to stir 10min;
(6) add leavening, static fermentation:
In raw milk after the pre-acidification of step (5), add leavening TCC-3 type 5-10U/100L cow's milk, stir 3min, be heated to 30-34 DEG C, and be incubated static fermentation 30-40min;
(7) add renin:
In raw milk after step (6) fermentation, add renin 2-4g/100L cow's milk, stir 3-5min, keep temperature 30-34 DEG C, static 45-60min, obtains curdled milk.
Beneficial effect:
1, the present invention adopts pre-acid adjustment, dry salt method, is incubated dry pulling method processing pizza cheese.Salt adding technique does not adopt traditional salt adding process of soaking salt solution salt adding after moulding, adopt stretch before dry mixing salt, saliferous hydro-thermal is boiled, in drawing process, add a small amount of salt, this method technique facilitates easy to operate, there is no a large amount of immersion salt solution, energy-efficient, reduce processing cost.
2, drawing process is after heat is boiled, to shift cheese to rub up stretching to being incubated the long period in stretching-machine, add a certain proportion of SPE simultaneously, green starch, aluminum phosphate sodium, heat is boiled while stretching, SPE under the ratio condition providing in the present invention, green starch, aluminum phosphate sodium has changed the inside matter structure of pizza cheese, their threes combine, the inside texture change of the pizza cheese bringing is far longer than the variation that independent use aluminum phosphate sodium brings, guarantee that the product forming does not need through post-mature 21-30 days, after production, can use, shorten the production cycle, reduce significantly production cost.
