Problems solved by technology

[0002] Vegetable pickling processing has a long history in our country, but the traditional vegetable pickling process uses high salt, the amount of salt is between 150-250g/kg for pickling, with the help of beneficial microorganisms naturally attached to the surface of vegetables, For example, lactic acid bacteria, carry out slow fermentation to produce acid, reduce the pH value of pickled products, and use the high osmotic pressure of salt to jointly inhibit the growth of harmful microorganisms. Generally, it takes 15-30 days of fermentation
[0003] Because of its good local flavor, pickled vegetables are easy to eat, and have been a favorite dish of people for a long time, but with the continuous improvement of people's living standards, there are the following problems in the pickled vegetables prepared by traditional crafts: (1) Vitamin C deficiency, vitamin C is destroyed in a large amount during the traditional pickling process, resulting in the lack of vitamin C in traditional pickled products; (2) High salt, in order to ensure that the edible pickles have the required taste, and to inhibit The role of harmful microorganisms, the salt content of pickled vegetables pickled by traditional pickling process is high, but high salt intake will cause permanent damage to some organs of the human body, such as the kidneys, cardiovascular system, and increased risk of high blood pressure

Embodiment 1

[0023] A method for pickling low-salt healthy-flavored pickled vegetables using ultra-high pressure technology, comprising the following steps:

[0024] (1) After cleaning the fresh white radish, cut it into pieces;

[0025] (2) Add 5% white vinegar water, the amount of white vinegar water is subject to the fact that the vegetables are submerged, soak for 60 minutes and remove;

[0026] (3) Put the vegetables into the high-pressure pickling tank, add 5% salt water, the weight ratio of the salt water to the vegetables is 0.8:1, seal it, and carry out ultra-high pressure treatment. The conditions are: temperature room temperature, pressure 400MPa, pressure holding time 10 minute;

[0027] (4) After the pressure is released, add 4 mL of 100 cfu / mL lactic acid bacteria strains to the high-pressure curing tank, seal the curing tank and ferment at 30 °C for 24 hours;

[0028] (5) Release the pressure in the pickling tank after fermentation, take out the pickled vegetables and add ...

Embodiment 2

[0030] A method for pickling low-salt healthy-flavored pickled vegetables using ultra-high pressure technology, comprising the following steps:

[0031] (1) After cleaning the fresh carrots, cut them into pieces;

[0032] (2) Add 7% white vinegar water, the amount of white vinegar water is subject to the fact that the vegetables are submerged, soak for 60 minutes and remove;

[0033] (3) Put the vegetables into the high-pressure pickling tank, add 7% salt water, the weight ratio of the amount of salt water to the vegetables is 1:1, seal it, and perform ultra-high pressure treatment, the conditions are: temperature room temperature, pressure 500MPa, holding time 8 minute;

[0034] (4) After the pressure is released, add 5 mL of 120 cfu / mL lactic acid bacteria strains to the high-pressure curing tank, seal the curing tank and ferment at 30 ° C for 24 hours;

[0035] (5) Release the pressure in the pickling tank after fermentation, take out the pickled vegetables and add cloves...

Abstract

The invention relates to a method for pickling low-salt healthy flavor pickled vegetables with an ultra-high pressure technology; through two times of ultra-high pressure treatment before and after pickling, the usage amount of table salt is reduced, the low-salt healthy pickled vegetables are prepared, the content of nitrite in the pickled vegetables is also reduced, colors of vegetables are preserved, the destruction of vitamin C in the vegetables is reduced, and the content of vitamin C in the pickled vegetables are increased; long-time preservation is achieved under a condition without addition of any preservative; the pickled vegetables not only having fragrant and sweet flavor but also having effects of clearing heat and detoxifying are provided by adding clove and liquorice.
