Description
Technical field
The invention belongs to grain processing fields, are related to a kind of corn powder producing method, and in particular to one kind is original with corn
Material, ferments to the corn after immersion using lactic acid bacteria, the method that wet grinding produces corn powder.
Background technique
Corn is a kind of crops planted extensively, and not only yield is high, but also full of nutrition.Utilize different processing methods
Multiple product can be prepared, the fields such as food, feed, brewing are applied to.Traditional corn processing is at the method for corn flour will be beautiful
The grain of rice is directly milled, or is milled after corn is removed the peel de- embryo.Since protein content is lower in corn, corn flour is not easy forming face
Group, therefore, all there is the problems such as bad mouthfeel, poor processability in the corn flour that both techniques produce.
In view of the above-mentioned problems, expanding the edible consumption amount of corn, domestic and international scientific research to improve the processing performance of corn flour
Personnel conduct extensive research corn processing technology, seek production technology appropriate and change to the processing performance of corn flour
It is good.
Summary of the invention
The object of the present invention is to provide a kind of wet process corn powder production method, this method can by corn all at
Divide and all enter in flour, does not generate any by-product, obtained corn powder remains whole nutrition in corn, processability
Can be excellent, it is in good taste with the food of this flour processing, it is full of nutrition, and simple production process, it is suitble to industrialized production.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of wet process corn powder production method, includes the following steps:
Step 1: carrying out extruding, control dilation (small product size and extruding after extruding using airflow puffing technology after corn removal of impurities
The ratio between preceding raw material volume) be 1.05 ~ 1.1,110 ~ 120 DEG C of airflow puffing cavity temperature, 0.1 ~ 0.2MPa of pressure；
Step 2: by 20 ~ 40%(mass percent) corn after extruding is broken into corn quarrel, with the whole grain after remaining extruding
Corn mixing, with 95 ~ 100 DEG C of 3 ~ 5min of hot water blanching；
Step 3: being cooled to 40 ~ 50 DEG C, the SODIUM PERCARBONATE for accounting for corn total weight 0. 1 ~ 0.5% is added, impregnates 60 ~ 100min；
Step 4: being washed till neutrality with water purification, it is placed in fermentor and is fermented with lactobacillus inoculation (lactobacillus plantarum), control inoculum concentration is
0.01 ~ 1%, 20 ~ 40 DEG C of fermentation temperature, 40 ~ 60h of fermentation time；
Step 5: being separated by solid-liquid separation after fermentation, it is milled after corn is washed with water using wet process, obtains full corn after dewatering slurries are dry
Powder.
Compared with the prior art, the present invention has the advantage that
The present invention improves the processing performance of corn flour using the technique that puffing technique is combined with lactobacillus-fermented, passes through
Extruding and lactobacillus-fermented change the molecular structure of corn internal component so that the hardness of manufactured corn flour, brittleness, viscosity,
The texture properties such as the apparent properties such as elasticity and its ductility, extensibility are improved.Improve the matter of corn flour by this technology
Structure performance obtains the better corn flour of processing performance, easy to process at a variety of wheaten foods, can not only enrich the meal of people
Table is conducive to national health, moreover it is possible to improve the productive value of corn and the plantation enthusiasm of vast farmers, be the development and utilization of corn
More new and innovative ways are provided.
Detailed description of the invention
Fig. 1 is wet process corn powder production technological process of the present invention.
Specific embodiment
Further description of the technical solution of the present invention with reference to the accompanying drawing, and however, it is not limited to this, all to this
Inventive technique scheme is modified or replaced equivalently, and without departing from the spirit and scope of the technical solution of the present invention, should all be covered
Within the protection scope of the present invention.
The present invention provides a kind of wet process corn powder production methods, as shown in Figure 1, described method includes following steps:
(1) corn pre-processes
The niblet of moisture content≤14% of no mildew is sent into magnetic separator and stoner by bucket elevator, except de-iron, stone etc.
Sundries screens out the sandy soil smaller than niblet and the jade bigger than niblet using the scalping of 6 ~ 8 purposes thin vibrating screen and 4 mesh
The skins such as meter slug particle are miscellaneous, and garbled niblet is sent into subsequent workshop section by auger conveyor.
(2) airflow puffing
Corn when raw material is in the state of high temperature and pressure, is discharged under normal temperature and pressure, internal is huge suddenly after extruding
Momentum is released, the liquid water vaporization diffusion under high temperature, so that raw material forms explosive state, the interior tissue of raw material
The blast action that rises is stretched, to become countless fine porous cavernous bodies, the lactobacillus-fermented for being very beneficial for raw material is modified.
The bulking process of corn need to control corn dilation (after extruding before small product size and extruding raw material volume it
Than), the degrees of expansion of control corn is reached by controlling airflow puffing parameter.The corn that dilation produces when being 1.05 ~ 1.1 is complete
Mealiness can be best.Airflow puffing technological parameter: 110 ~ 120 DEG C of cavity temperature, 0.1 ~ 0.2MPa of pressure.
(3) corn is broken
The corn after extruding is crushed with hominy mill, it is whole kernel corn is broken, it is therefore an objective in later stage fermentation mistake
Cheng Zhongneng quickly supplies nutrients for lactic acid bacteria.Broken corn accounts for the 30% of total amount.
(4) it impregnates
30% corn is cut and is mixed with 70% niblet, with 95 DEG C of hot water blanching 4min, 45 DEG C is cooled to, it is total that 0.1%(is added
SODIUM PERCARBONATE again) continues to impregnate 80min.
(5) it ferments
Corn after immersion is washed till neutrality with water purification, is placed in fermentor and is fermented with lactobacillus inoculation, and control inoculum concentration is 0.01%,
30 DEG C of fermentation temperature, fermentation time 48h.
Fermenting microbe is lactobacillus plantarum, the lactobacillus plantarum saved is accessed in MRS liquid culture medium, 32
DEG C, cultivate 24 h in 120 r/min shaking tables, fermentation seed liquid is made.Seed liquor bacterium number is 1 ~ 3 × 107cfu/ml。
(6) tunning separates
It will be separated by solid-liquid separation after fermentation, liquid returns to fermentor as fermentation mother liquor.After lactic acid bacteria is washed with water in corn after fermentation
Milling.
(7) defibrination
It is milled using wet process.By after fermentation corn and water in the ratio (mass ratio) of 1:4, ground with fiberizer, fine powder passes through
The sieve of 100 mesh of fiberizer, coarse granule is ground repeatedly makes its whole pass through 100 mesh sieve, and corn whole component all enters
In starch adhesive.
(8) it dehydrates
Wet face block is obtained after starch adhesive dehydration, heated-air drying is then used, obtains aqueous 5% corn powder after broken.It is packed after cooling
Storage.
