Description

A kind of brine of pickled mustard tuber technology

Technical field

The invention belongs to the salted vegetable production technical field, be specifically related to a kind of brine of pickled mustard tuber technology.

Technical background

There is the long history of Pickle in China, and especially the hot pickled mustard tube manufacturing technology world is famous.Hot pickled mustard tube is to do raw material with the green vegetables head, because green vegetables head water content height, the band bitter taste needs in the manufacturing process through squeezing to get rid of moisture and bitter taste.The traditional manufacturing technique of hot pickled mustard tube comprises: classification is drawn the piece-string dish airing-undercarriage peeling-head pond-two that salts down-turn over and is salted down-prune and see muscle-shaping classification-elutriation-squeezing-spice-dress altar-tying-after-ripening-finished product, head salted down 4 days, two salted down 8 days, after-ripening was opened the altar inspection and once (is seen calendar year 2001 China Light Industry Press's publication " salted vegetable production practical technique ") more than 3 months in 30-40 days.This process procedure is many, and is long in time limit, and most operations are open type operations, easily pollution, difficult monitoring.Dehalogenation, flushing several times both made the salt content height in the dish, discharges and contaminated environment, but also nutrition is seriously run off, and the hot pickled mustard tube ubiquity that traditional handicraft is produced is of low nutritive value, and the shortcoming that yield rate is low is effectively solved always.

Summary of the invention

The present invention is directed to the prior art above shortcomings, purpose is to provide a kind of technology of making hot pickled mustard tube, by fermentation tank with the dish piece flood the after-ripening that salts down, ferments be integrated into one the step finish, both greatly reduced required salinity, guaranteed that again nutrition do not run off, the bright delicious and crisp of taste is tender, has also simplified technological process, avoids contaminated environment.

Technical solution of the present invention is as follows:

Brine of pickled mustard tuber adopts following processing step:

(1) cleaning, air-dry dehydration

(2) with sealing in the rolling fermentation tank of packing into behind the salt 3-5% mixing;

(3) roll/shake fermentation tank or jar in stir, the dish piece is rolled in jar, flood and salt and the after-ripening of fermenting time 5-8 week down.

(4) take out the dish piece, chopping, perfuming, sterilization, packing get finished product.

The rolling of the fermentation tank that adopts in this technology/shake or stirring movement speed 20-30cm/ second; The period of motion is: first week was decremented to 3-5 minute from 10-15 minute from per hour being decremented to for 1 time 8-12 hour 1 time at every turn, remaining several weeks, 12 hours every days 1 time, each 3-5 minute; Temperature is controlled in the 15-25 ℃ of scope.

In flooding the sweat that salts down, carry out pH value, temperature, sugared salinity, gas pressure, microorganism etc. to salted vegetables in the jar and monitor and regulate and control.

Key of the present invention is that the seal-moving that adopts fermentation tank to carry out floods the sweat that salts down, this process makes the dish piece that following variation take place in jar: beginning is because bittern is oozed out in the union dyeing of salt grain, just begin to be participated in by microorganisms such as various lactic acid bacterias natural fermented, the gas of its generation has suppressed the breeding of spoilage organisms again.Biochemical reactions through a series of microorganism makes the slaking day by day of dish piece.After fermentation was finished, gas reduced day by day, until stopping; Bittern all returns again at last and oozes back in the dish piece from less to more simultaneously.This technical process is brought the advantage of following several respects: the head that 1, has changed traditional manufacturing technique salts down, two salts, presses various operations such as water, after-ripening down, and length consuming time by the seal-moving fermentation tank, concentrates on one and goes on foot and finish, and has obviously simplified technology, has saved the time.2, the salt amount that drops into of traditional manufacturing technique is very high, the waste resource, and the row's of pickling halogen has been taken away a large amount of nutrition again several times, being of low nutritive value of finished product, mouthfeel is undesirable.And the present invention by sealed rolling flood salt down the fermentation one the step finish, biochemical reaction by nature makes the thick gravy generation return the variation of oozing back by being exuded to, the salt amount that adds is few, need not press water, both guaranteed that nutritional labeling do not lose, can also react the microorganism, the beneficial bacterium that obtain multiple beneficial, have higher nutritive value and the tender mouthfeel of bright delicious and crisp.3, main to flood the fermentation after-ripening process that salts down all be to finish in confined conditions, prevented pollution, edible safer.

This shows that brine of pickled mustard tuber technology of the present invention had both improved the nutritive value of hot pickled mustard tube, simplified technology again, shortened the production cycle, sanitation and hygiene, more meet the consumption demand of current people's pursuing high quality, high nutrition.
