Description

A kind of pickle production method of adding clitocybe maxima

Technical field:

The present invention utilizes clitocybe maxima fructification to reduce Nitrite in Pickles content and improves the method for pickle flavor, belongs to field of food.

Technical background:

Pickles are a kind of traditional foods of China, have the long history of more than 2000 year.It is mixed fermentation vegetables based on lactic acid bacteria in natural environment and flavoring, because local flavor is good to eat, be easy to store, nutrient health, therefore become a kind of popular food that Chinese generally like.

But the nitrite problem in pickles always is and receives much concern.Nitrite in pickles due in pickled and sweat nitrate reductase be that nitrite causes by the nitrate reduction in vegetables.After human body takes in nitrite, nitrogen-containing compound (secondary amine, tertiary amine, acid amides and amino acid) in nitrous acid and stomach is combined into the health of the direct harmful to human of the nitrosamine with carcinogenicity, people are quite scrupled for the consumption of pickles, and this becomes one of key factor of restriction pickles development.

Clear stipulaties in national standard (GB2762 ?2005), the content of catsup and pickled vegetables nitrite should more than 20mg/kg sample.In order to reduce the content of nitrite in catsup and pickled vegetables, Chinese scholars has carried out in many ways making great efforts.

At present, the method reducing Nitrite in Pickles mainly contains two classes: a class is by biodegradable method, namely the fermentation strain of the artificial method seed selection high degradability be separated is adopted, carry out method that is purebred or fermented by mixed bacterium, get rid of reproducibility as far as possible and to mix the increase of microbial content of nitrite.Another kind of is adopt the method for physics and chemistry, by the negative effect regulating the osmotic pressure of zymotic fluid or regulate the one-tenth of zymotic fluid to assign to suppress reproducibility microorganism to cause, as added material containing sulfydryl, hydroxyl to reduce the content of nitrite.

And under study for action, the discovery of our novelty adds clitocybe maxima fructification can reduce content of nitrite in pickles, and successful.The present invention, by adding clitocybe maxima fructification in the curing process of pickles, provides a kind of new technology and thinking for reducing Nitrite in Pickles content.

Summary of the invention
