Technical field
The invention belongs to kimchi foodstuffs processing technique field, more particularly to a kind of many wheel salting zymolysis technology processing pickles
Method.
Background technology
Pickles are the Typical Representatives of China's traditional characteristicses fermented food, and with a long history, cultural deposits are deep.In the market
The kimchi products sold are with the vegetable of salting as primary raw material mostly, through over cleaning, desalination, dehydration, seasoning, packaging and sterilization
The seasoning kimchi products producing etc. operation.One of necessary operation as modern production Pickles vegetable salting, it determines
The final quality of kimchi products.
The salting of existing vegetable raw-material typically adopts a salting method, after that is, fresh vegetabless are received during salting, disposably will
Required total salt dosage fills up, and no longer adds later.There is following technical problem during this:
First, salt consumption is big, and high concentration Sal causes the violent osmosiss of vegetable plant cells to make vegetable tissue suddenly
Dehydration, leads to vegetable that elephant skin and deflation occur, outward appearance is not full.
2nd, the concentration of salting solution is big, and the moisture in vegetable tissue and solable matter are by cell membrane extravasation and high
The time that concentration salt solution reaches balance is just grown so that the salting zymolysis time is that the production cycle is longer, and because high salinity
Salting solution can produce more nitrite under long duration of action, affects health of people.
3rd, the concentration of salting solution is big, and the lactobacilluss in Pickles are difficult to growth and breeding, and content of lactic acid bacteria is low, and lactic acid is sent out
Ferment is slow, and product special flavour is single, and nutritive value is relatively low.
4th, because of once input and sweat is slow for salting solution, is also easy to produce miscellaneous bacteria, the quality of impact product.
In addition, carried out brewed in conventional Kimchi with single water or saline, local flavor is not enough.
Content of the invention
In order to solve above technical problem, the present invention provides a kind of method taking turns salting zymolysis Pickles more, solves existing skill
Art medium salting fermentation period is longer, and content of nitrite is higher, the low problem of content of lactic acid bacteria, improve kimchi products local flavor and
Mouthfeel, makes that Pickles are healthy, being rich in nutrition value.
Solve a kind of methods of many wheel salting zymolysis Pickles in the present invention of above technical problem it is characterised in that:In vegetable
During dish salting zymolysis, after reaching certain acidity, carry out sediment upturning, make the vegetable fermented be located at lower section, fresh vegetable is added in top

It is essentially identical from the experimental result fermentation liquid stain dish of Fig. 1,2,3 and table 7 and the salinity altercation trend of the water stain dish of Sal,
In salting 120d, salinity is all down to 6.3% about from 15%;Total acid variation tendency slightly difference, reclaims the initial total acid of salt accumulated water
For 0.6%, therefore it is more easy to start lactate fermentation, in subsequent fermentations, shows slightly advantage;Nitrite aspect, reclaims salt accumulated water
With the obvious advantage, show that nitrous peak occurs slightly early(During fermentation 40d), nitrous peak value relatively low(63mg/kg), and the water stain dish of Sal is sub-
Slightly evening in nitre peak(During fermentation 50d), nitrous peak value higher(98mg/kg);Sensory evaluation aspect, reclaims the water stain famished look of salting
, closer to ripe pickled tuber mustard, ferment local-flavor is dense for pool, flavour, brittleness, and the water stain dish of Sal is more aobvious jerky, with ripe pickled tuber mustard gap
Larger.
Comprehensive above experimental result determines, fermentation liquid stain dish relatively eat salted, salting zymolysis startup faster, more active,
While ensureing salted quality, production efficiency is improved.
The analysis of the main influence factor of fermentation liquid adsorption treatment:
The main influence factor of fermentation liquid adsorption treatment is activated carbon and diatomaceous addition, and concrete analysis is as follows.
1st, the impact to fermentation liquor treatment effect for the activated carbon addition
Other contents such as embodiment 1, kieselguhr addition is fixed on 0.2%, changes activated carbon addition(0.1%、
0.2%、0.3%、0.4%、0.5%), with salt accumulated water light transmittance and salinity as evaluation index, determine suitable activated carbon addition.Real
Test result as shown in Figure 4,5.
Knowable to Fig. 4,5 result, when kieselguhr addition is fixing, the addition of activated carbon is larger to Effects of Salinity, just
Beginning salinity is 15% fermentation liquid, and when activated carbon addition is incremented to 0.5% for 0, when 15% is down to 9.5%, loss is relatively for its salinity
Many, but when addition is 0~0.2%, salinity loss is more slow;The addition of activated carbon when 0 is incremented to 0.1%, fermentation liquid printing opacity
Rate increases to 51% from 21%, and increasing degree is very big, and when 0.1%~0.2, light transmittance increases to 65% from 51% to addition, increasing option,
When being added to 0.2%~0.5%, light transmittance change is less.Therefore, activated carbon has considerable influence to fermentation liquid salinity, for ensureing
Less Sal loss and preferable impurity-eliminating effect, and become the consideration of present aspect, 0.2% activated carbon addition is more suitable.
2nd, the impact to fermentation liquor treatment effect for the kieselguhr addition
Activated carbon addition is fixed on 0.2% by this experiment, changes kieselguhr addition(0.1%、0.2%、0.3%、0.4%、
0.5%), with fermentation liquid light transmittance and salinity as evaluation index, determine suitable kieselguhr addition.Experimental result such as Fig. 6,7 institutes
Show.
Knowable to Fig. 6,7 result, when activated carbon addition is fixing, diatomaceous addition is little to Effects of Salinity, just
Beginning salinity is 15% fermentation liquid, and after the adsorption filtration of activated carbon, salinity is 13.84%, when kieselguhr addition is from 0.1%
When being incremented to 0.5%, fermentation liquid salinity is down to 13.45% from 13.84 only %;And diatomaceous addition has to fermentation liquid light transmittance
Considerable influence, initial light transmission is 21.17% salt accumulated water, and after the adsorption filtration of activated carbon, light transmittance is 65.12%, when
When 0 is incremented to 0.1%, fermentation liquid light transmittance increases to 75.54% from 65.12% to kieselguhr addition, and addition is 0.1%~0.5%
When, light transmittance change is less.Therefore, diatomaceous addition 0.1% is advisable.
