Embodiment 1
[0049] A kind of preparation method that can reduce traditional kimchi biogenic amine, its steps are as follows:
[0050] (1) Activate and enrich the obtained Lactococcus lactis and Lactobacillus pentosus, which have a strong ability to degrade biogenic amines and have a good flavor, and centrifuge at 8000r / min for 10 minutes at low temperature to take the sludge for use;
[0051] (2) Pretreatment of kimchi raw material and kimchi mother water: the kimchi is cleaned, drowned, then sealed and packaged, and irradiated together with auxiliary materials, and the irradiation dose is 2kGy. Take the mature kimchi mother water and filter it under 100 mesh nylon cloth, then centrifuge at 10000r / min for 10 minutes, take the supernatant and filter it with a 0.22um membrane to obtain the kimchi water filtrate;
[0052] (3) Preparation of pickles: add irradiated vegetables and auxiliary materials in proportion to the sterilized pickle jar, then add sterile saline to it, and stir and mix; t...
Embodiment 2
[0056] (1) Activate and enrich the obtained Lactococcus lactis and Lactobacillus pentosus, which have a strong ability to degrade biogenic amines and have a good flavor, and centrifuge at 8000r / min for 10 minutes at low temperature to take the sludge for use;
[0057] (2) Pretreatment of kimchi raw material and kimchi mother water: the kimchi is cleaned, drowned, then sealed and packaged, and then irradiated. The irradiation dose is 5kGy. Take the mature kimchi mother water and filter it under 100 mesh nylon cloth, then centrifuge at 8000r / min for 10 minutes, take the supernatant and filter it with a 0.22um membrane to obtain the kimchi water filtrate;
[0058] (3) Preparation of pickles: add irradiated vegetables and auxiliary materials in proportion to the sterilized pickle jar, then add sterile saline to it, and stir and mix; the auxiliary materials can be ginger, garlic, red Capsicum, Chinese prickly ash and glucose etc. The addition of ginger is 1%, the addition of garli...

Abstract
The invention relates to the technical field of processing of pickled vegetables, in particular to a preparation method capable of reducing biogenic amine of conventional pickled vegetables. The method comprises the following steps of (1) screening bacterial strains capable of degrading biogenic amine; (2) re-screening bacterial strains good in flavor; (3) preparing obtained lactobacillus pentosusand obtained lactococcus lactis which are high in capacity of degrading the biogenic amine and good in flavor into bacterium paste; (4) performing radiation treatment on raw materials of the pickledvegetables; (5) preparing the pickled vegetables; and (7) adding glucose, aged water for making pickled vegetables, glycine, gluconolactone and the like. The conventional Sichuan pickled vegetables obtained by the method disclosed by the invention are low in the content of the biogenic amine, appropriate in acidity and good in flavor.
Description
technical field [0001] The invention belongs to the technical field of pickle processing, in particular to a preparation method capable of reducing traditional pickle biogenic amines. Background technique [0002] Biogenic amines are a general term for a class of biologically active small-molecular-weight nitrogen-containing compounds mainly formed through the decarboxylation of amino acids or the amination of aldehydes and ketones. Biogenic amines are normal active ingredients in living organisms, which have significant antioxidant effects, regulate blood pressure, regulate norepinephrine levels, increase heart rate, blood pressure and blood sugar concentration, etc. An appropriate amount of biogenic amines is beneficial to the health of the human body, but excessive biogenic amines can poison the human body and cause serious consequences, such as headaches, blood pressure changes, respiratory disorders, heart palpitations, vomiting and other serious reactions. Fruits, veg...
