Description

A kind of preparation method of natto
Technical field
The invention belongs to fermented food technical field, more particularly to a kind of preparation method of natto.
Background technology
Guizhou Province's Homemade bacteria type natto is with a long history, and not only there is natto the pungent fragrant delicious, degree of saltiness to fit Preferably, sticky appropriate the characteristics of.The healthcare function such as also there is warming middle-JIAO and strengthening the spleen, invigorating Qi and tonifying kidney, nourishing to moisturize, stimulate the circulation of the blood and cause the muscles and joints to relax, therefore be The local special flavouring of name among the people.
The manufacture craft of Guizhou bacteria type natto among the people is that in the winter time before the beginning of spring, the black soya bean being cooked or soya bean cover Straw or cushaw leaf heat insulating culture.There is slime in beans surface colonization in bacterium after 2d, when can be pulled into silk and have peat-reek Salt, white wine and other auxiliary materials are added, fermentation 5-7d is ripe.Participating in the strain of bacterial fermented douchi fermentation has bacillus, microballoon Not only quantity is protruded in fermented soya bean for bacterium and lactic acid bacteria etc., wherein bacillus, and contains a large amount of enzymes for forming fermented soya bean local flavor Material, therefore bacillus plays very important effect in the fermentation process of fermented soya bean.
Bacterial fermented douchi is, using microorganisms such as bacillus subtilis, lactic acid bacteria and the saccharomycete in nature, to fall into ripe In soya broth, satiny mucus is coated with by controlling its suitable temperature, humidity to be trained beans, is glued when turning The fermented soya bean of liquid into wire drawing shape are bent, then through mixing salt, adding water and spice progress after fermentation, are finally made with the pungent fragrant delicious, degree of saltiness Suitably, the natto of sticky appropriate characteristic.In whole manufacturing process, the synergy of multiple-microorganism together form water beans The flavor substance of fermented soya beans, salted or other wise.
The bent suitable cultivation temperature of bacterial fermented douchi is at 45-50 DEG C, and reflect can't be by must make before the beginning of spring in the winter time Seasonal limitation.But after the beginning of spring, fermented soya bean song enters the 3rd day of after fermentation, the breathing produced due to microbial fermentation Heat can produce a large amount of gases with decomposition heat, and beans color and luster shoals, and pH value declines, and bubble occurs in liquid level, and such as processing will not in time Cause natto to become sour, stench.
The natto produced now typically all can be by high-temperature sterilization processing, but during keeping, acid also still occurs Lose, the phenomenon of dished cover, the factor for causing natto putrid and deteriorated is more, mainly there is the factors such as chemistry, biochemical and microorganism, wherein Microorganism accounts for leading role.Microorganism will be killed or suppress its growth and breeding by extending the shelf-life of food.Although high temperature can With a certain degree of killing bacterium, but all bacterial micro-organisms can not be worked, putrid and deteriorated after being leaves hidden danger.
The content of the invention
The invention is intended to provide a kind of preparation method of natto, become sour with easy produce of natto for solving to make at present Phenomenon.
The preparation method of a kind of natto in this programme, it is characterised in that comprise the following steps:
Step 1: Feedstock treating:Soybean 1500g is taken, 3 ~ 5h is soaked with 20 ~ 30 DEG C of warm water, then takes out soybean, 9 ~ 15min is steamed under 0.15Mpa pressurization, the soybean cooked;
Step 2: fermented soya bean song culture:When ripe beans naturally cool to 45 ~ 50 DEG C, soybean is wrapped with cloth, surrounding is put into and fills up too In the carton of empty cotton, and pillow insulation is up covered, 23 ~ 26h is placed at 24 ~ 26 DEG C of room temperature, removes pillow, continues to place 35 ~ 37h, is made fermented soya bean bent;
Step 3: fermentation:Salt 400g, ginger rice 350g and Chinese prickly ash 10g are added in fermented soya bean are bent, is put into has cleaned and steam together In the fermentation tank sterilized, add cold boiling water 3700ml, the rear seal-cover that stirs fermentation, room temperature control during fermentation 23 ~ 25℃;, during fermentation, every 12h gentle agitations once, 88 ~ 92h of fermentation is treated, obtains the natto of maturation;
Step 4: regulation pH:8 ~ 10 lemon tablets are placed on the surface of natto, then with watering pot by 30 ~ 35 DEG C of warm water Slow uniformly pour is sprinkled upon on lemon tablet, and warm water pours the amount of spilling for 0.5kg, is poured to spill and is finished rear seal-cover and place 1h, takes out lemon tablet;
Step 5: seasoning:Capsicum 40g is put into, is stirred;
Step 6: sterilization filling;90 ~ 93 DEG C are heated to, 20min is maintained, while hot filling bottle.
The principle and beneficial effect of the present invention:Compared with existing natto manufacture craft, the application has advantages below:
1st, during the processing of traditional natto, all it is soybean meeting roll-over crash in boiling water by the way of boiling water cooked beans, works as soybean When being cooked, it is easily caused soybean and ruptures, it is difficult to ensure that soybean has more intact profile, is unfavorable for follow-up processing.And The application steams 9 ~ 15min of beans using 0.15Mpa pressurization, will not roll-over crash between soybean, it is ensured that the intact profile of soybean, soft Hard degree is also just adapted to the processing of fermented soya bean.And the time of cooked beans comes in 1 ~ 1.5h, 9 ~ 15min of steaming beans compared to the application Say, it is clear that it is very long a lot, for the industrial production of modernization, shorten production time of 1 hour, enterprise can be significantly increased Production efficiency.
2nd, when carrying out fermentation step, the respiration heat and decomposition heat produced due to microbial fermentation can produce a large amount of gases, Beans color and luster shoals, and pH values decline, and bubble occurs in liquid level, such as not in time processing natto will be caused to become sour, stench, this Shen Please in fermentation step, every 12h gentle agitation once, carbon dioxide therein is discharged, allows pH value to return to normal value, Also so that the fermentation of microorganism is normally carried out, it is to avoid natto becomes sour, the generation of stench phenomenon.
3rd, vital movement influence of the pH value of regulation natto on microorganism is very big, and every kind of microorganism has its certain life Long pH scopes and most suitable pH value.The optimal pH of most of bacteriums is 6.5-7.5, and actinomyces optimal pH is 7.5-8.0, yeast Then it is suitable to pH5.0-6.0 sour environment with mould.Below pH4.3, in addition to yeast, mould still have propagation, bacterium is substantially without numerous Grow ability.Natto is during preserving, and recurrent " dished cover " phenomenon is due to that the bacterial micro-organism in natto is not complete Kill, cause when stored, microorganism in natto, which continues to ferment, produces gas, so that lid is raised, when more crucial, The continuation fermentation of these bacterial micro-organisms, can cause becoming sour for natto, have a strong impact on the preservation of natto.The application is from pure Natural lemon tablet, the natural lemon acid that is carried using it adjusts the pH value in natto, and lemon tablet is laid in into natto Surface, then slowly poured and be sprinkled upon on lemon tablet with 30 ~ 35 DEG C of warm water, in this stage, warm water can be with the lemon in lemon tablet Acid is penetrated into natto, reduces the pH value of natto, after 1h to be placed, the pH value in natto can be maintained at 4.2 ~ 4.3 it Between, 90 ~ 93 DEG C are then heated to, 20min is maintained, can effectively kill the bacterial micro-organism in natto, prevents from continuing production of fermenting Angry body, extends the shelf-life of natto.
Further, in the step one, the time with warm water soaking soybean is 3.5h, when this is optimum immersion Between, it can allow the abundant foaming of soybean, allow follow-up steaming beans to operate more smooth.
Further, in the step 3, during fermentation every 12h stirrings once, the time stirred every time is no more than 2min, it is to avoid oxygen-abundant to enter for a long time in the air of exposure, can allow fermentation to produce uneven, influence the progress of fermentation.
Further, in the step 4,5 ~ 7g sodium benzoates are added, anti-corrosive properties when natto is preserved can be increased, And this addition is safe scope, will not produce harmful influence.
