Description
Technical field
The present invention relates to microbe application in food processing technology field, particularly relate to the inferior Dbaly yeast bacterium of a kind of Chinese and zymotic fluid thereof, also relate to the mixed culture fermentation liquid containing the inferior Dbaly yeast bacterium of this Chinese and this application of mixed culture fermentation liquid in vegetables secondary fermentation.
Background technology
Fermented vegetable is an important kind in people's conventional food, and the vegetable variety related to is a lot.Fermentation process in its process is fermentation method and secondary fermentation once, vegetables after one time fermentation are generally semi-finished product, need eat after secondary operations, secondary operations can, by bakery and confectionery batch machining, also can be that the semi-finished product after people buy one time fermentation carry out directly eating after seasoning is cooked according to personal like.Usually unstable by the quality of vegetable after first time fermentation, the fermented vegetable that each Batch fermentation is produced is at matter structure, color, the aspects such as local flavor are usually inconsistent, pass through secondary fermentation, the quality of fermented vegetable can be made to reach more homogeneous, simultaneously, pass through secondary fermentation, the edible safety of fermented vegetable can be made to be improved, abatement harmful microorganism, the injurious factors such as nitrite, reduce the salt content of fermented vegetable, the distinctive excellent flavor material of more fermented vegetables is generated can be increased the nutritive value of fermented vegetable by artificial infection beneficial microbe in secondary fermentation process while, improve the bad flavor formed in first time sweat.Secondary fermentation has become the important trend of current fermented vegetable making food.
Saccharomycete is to the storage important after the local flavor of fermented vegetable and quality and fermentation.During fermented vegetable, the microbial fermentation of yeast generates ethanol, and to the curing food after-ripening stage, esterification occurs and generate aromatic substance very important, the generation of other alcohols also has certain influence to local flavor.Saccharomycete plays beneficial effect utilizing in fermentable sugars.To the active lactic acid bacteria of fermented vegetable once complete the suppression that fermentation can be subject to low ph value, sugar fermentation can not be recycled, at this moment saccharomycete still can growth and breeding well, until residual sugar is run out, this point is especially true to fermented vegetables such as the carrots containing a large amount of sugar, because harmful bacteria such as spoilage organisms utilizes fermentable sugars that curing food can be caused corrupt.But if do not controlled saccharomycetic alcoholic fermentation for a long time, curing food alcoholic strength is too high, can damage normal flavor.In addition, the amount reproduction of some saccharomycete as produced uncut jade yeast can make the raw flower in the surface of curing food, and long tunica albuginea, produces offending acid smell, finally causes curing food to go bad, therefore, often saccharomycete is regarded as the spoilage organisms of fermented vegetable.Yeast can also produce CO
2, cause pickled cucumber gaseous spoilage.If pickle the salinity of wild cabbage higher than 3%, Rhodotorula bacterium may grow causes punctation on pickles.Oxidation yeast can utilize lactic acid and lower salt solution, and cause other spoilage organisms to grow, but this only just can occur under aerobic conditions, because under anaerobic, these saccharomycete can not utilize organic acid.
Pickles are traditional zymotic vegetables of China, have delicious, that clearly good to eat, the short digestion of appetizing etc. the is many advantage of fresh acid, dark liking by our people.Pickles form primarily of lactobacillus-fermented, lactobacillus-fermented produces a large amount of organic acids, saccharomycetes to make fermentation produces a large amount of alcohols flavor components, and pickle fermentation maturation takes pasteurize afterwards usually, but through thermally-sterilized pickles brittleness reduction, colour-darkening, flavor loss.The common problem that fermented vegetable industry exists is during shelf life, occur producing Inflatable bag, rotten, normally because saccharomycete causes.
Current vegetables secondary fermentation does not manually add yeast, if but wild yeasts wherein for a long time its alcoholic fermentation is not controlled, curing food alcoholic strength is too high, can damage normal flavor.In addition, the amount reproduction of some saccharomycete as produced uncut jade yeast can make the raw flower in the surface of curing food, and long tunica albuginea, produces offending acid smell, finally causes curing food to go bad.Yeast can also produce CO
2, cause aerogenesis, easily occur producing Inflatable bag, going bad during shelf life.Under aerobic conditions, be oxidized yeast can utilize lactic acid and lower salt solution, cause other spoilage organisms to grow.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art, a kind of inferior Dbaly yeast bacterium of the Chinese that can be applicable to vegetables secondary fermentation is provided, additionally provide a kind of zymotic fluid by obtaining after the inferior Dbaly yeast bacterium fermentation of the Chinese, this zymotic fluid can ferment with Lactobacillus plantarum zymotic fluid, Leuconostoc mesenteroides and be prepared into mixed culture fermentation liquid, is applied to the secondary fermentation of vegetables.
For solving the problems of the technologies described above, provide the inferior Dbaly yeast bacterium of a kind of Chinese, the aforementioned Chinese inferior Dbaly yeast bacterium is the inferior Dbaly yeast of the Chinese (Debaryomyces hansenii) W08, be preserved in China Committee for Culture Collection of Microorganisms's common micro-organisms center on February 17th, 2012, deposit number is: CGMCC No.5770, preservation address: No. 3, Yard 1, BeiChen xi Road, Chaoyang District, Beijing City Institute of Microorganism, Academia Sinica.
