Abstract

The invention belongs to the field of food processing, and particularly relates to a method for making bacteriostatic-agent dry powder with pickle brine. The method includes the following steps that 1, green vegetables are cut, washed and drained; 2, the green vegetables and salt brine are mixed and put into an incubator to be cultivated for 7-12 days, and the pickle brine is taken; 3, the pickle brine is subjected to water-bath heating for 10 min and naturally cooled, centrifugation is carried out for 5 min through a centrifugal machine, and supernatant liquid is taken; 4, the supernatant liquid is filtered through a filtering film, the pH of filtered liquid is adjusted, then the filtered liquid is subjected to a bacteriostatic test, and supernatant liquid, containing obvious bacteriostatic rings, in the filtered liquid subjected to the bacteriostatic test is subjected to concentration and spray drying to obtain the bacteriostatic-agent dry powder. As the bacteriostatic-agent dry powder is added in the preliminary stage of pickle fermentation, growth of common pickle pathogenic bacteria such as Escherichia coli, staphylococcus aureus and Listeriosis can be inhibited, the number of active lactic acid bacteria in pickles can be increased, and the quality and the safety of the pickles are improved.

Description

A kind of method utilizing pickles bittern to make bacteriostatic agent dry powder
Technical field
The invention belongs to food processing field, be specially a kind of method utilizing pickles bittern to make bacteriostatic agent dry powder.
Background technology
Pickles i.e. " brine cure dish " is immersed in the salt solution of low concentration by fresh vegetables, and forming through the fermentation of lactic acid bacteria is brewed, is spontaneous fermentation food often edible in people's daily life.Pickle fermentation is a kind of zymotechnique of lactic acid with more than 2000 year history.Pickle fermentation is lactic fermentation mainly, a large amount of organic acid can be produced in sweat, bacteriocin, probios etc., can regulate animal and human's body intestinal microecology to balance, very useful to the health of body, and helpful digestion, prevent constipation, prevent cell senescence, reduce cholesterol, antitumor and regulate the health keeping and medical function such as human physiological functions.But at the pickle fermentation initial stage, because in yeasting, lactic acid bacteria not yet becomes dominant bacteria, the harmful microorganism such as enterobacteriaceae lactobacteriaceae, fungi will amount reproduction, affect product special flavour, accumulation nitroso compound and generation toxin (as enterotoxin, mycotoxin etc.), have a strong impact on the security of product.Therefore, make pickles at the dominant growth of fermentation initial stage lactic acid bacteria and effectively suppress harmful microorganism to become a great problem in pickled vegetable making process.
For improving quality and the security of China's pickles, by a series of experimental study, invent a kind of method utilizing pickles bittern to make bacteriostatic agent dry powder.By adding the growth that bacteriostatic agent suppresses miscellaneous bacteria at the fermentation initial stage, lactic acid bacteria is bred faster, impart the local flavor of pickles uniqueness and abundant nutritive value.
This patent introduces a kind of method utilizing pickles bittern to make bacteriostatic agent dry powder, bacteriostatic agent is added at the pickle fermentation initial stage, the growth of the common pathogens such as ETEC in pickles, staphylococcus aureus, listeria spp can be suppressed, shorten the time of pickle fermentation simultaneously, add biodiasmin quantity in pickles.Improve quality and the security of pickles.
Summary of the invention
The object of the invention is for above technical problem, there is provided a kind of and pickles making from brine is made bacteriostatic agent powder, can add at the fermentation initial stage of pickles the growth that bacteriostatic agent can suppress miscellaneous bacteria, increase the quantity of biodiasmin in pickles, improve quality and the security of pickles.To use simple, convenient simultaneously, is convenient to store and transport.
To achieve these goals, concrete technical scheme of the present invention is:
Utilize pickles bittern to make a method for bacteriostatic agent dry powder, comprise the following steps:
(1) fresh green vegetables carried out cutting, clean, drain stand-by; Described cutting refers to and green vegetables is cut into bar shaped or bulk, length × wide=2 × 2-4 × 4cm, and described draining refers to and drain to green vegetables surface green vegetables without the obvious globule.
(2) ratio being 1:1 in mass ratio by green vegetables and salt solution mixes, and the salinity of salt solution is 1%-5%, then puts into after 20-35 DEG C of incubator cultivates 7-12 days and gets pickles water;
(3) pickles water is put into 80-90 DEG C of water heating water bath 10min, naturally cool to 10-30 DEG C, with 10000r/min centrifuge 5min, get supernatant;
(4) supernatant is carried out filtration treatment by the filter membrane that aperture is 0.2-0.5 μm, with NaOH and HCl, the pH value of filtrate is adjusted to 6-7, then filtrate is carried out bacteriostatic test;
(5) have the supernatant of obvious inhibition zone to concentrate by the filtrate of carrying out bacteriostatic test, and Direct spraying drying is made into bacteriostatic agent.Described concentrates supernatant, and its mass percentage being concentrated into solid content in solution is 50-80%.Spraying dry, the inlet temperature of its drier is 120-150 DEG C; Outlet temperature is 98-110 DEG C.
Described green vegetables are Chinese cabbage.Described bacteriostatic test refers to the growth of the pathogenic bacteria suppressing common in the pickles such as ETEC, staphylococcus aureus, listeria spp with filtered fluid.The size of inhibition zone is observed by Odontothrips loti.Occur that obvious inhibition zone illustrates in pickles water and contain antibacterial substance, occur that the filtrate of obvious inhibition zone is used for making bacteriostatic agent.
Good effect of the present invention is:
(1), pickles making from brine is made bacteriostatic agent powder, the growth of pathogenic bacteria common in pickles such as can suppressing ETEC, staphylococcus aureus, listeria spp is added at the fermentation initial stage of pickles, increase the quantity of biodiasmin in pickles, improve quality and the security of pickles.
(2), use simply, conveniently, be convenient to store and transport.
