Abstract
The inventiion relates to a production method of corn flour. The production method comprises the steps of soaking corn grains in 90-95 DEG C water with pH 5.6-5.9 until water content of the corn grains reaches 35-45%; cooling the temperature of soaking water to 30-40 DEG C, adding lactic acid bacteria or yeast; adding saccharifying enzyme and xylanase when the soaking water pH lowers to 5; when the soaking water pH lowers to 4.5, washing corn grains with clear water or soaking corn grains with weak alkaline water until corn grains pH reaches 6.5-7.5; collecting corn grains; and preparing into whole corn flour with water content of 2-5%. The corn flour has the advantages of good mouth feeling and simple production process.
Description
Technical field
The present invention relates to the grain processing field, especially relate to a kind of production method of corn flour.
Background technology
Existing technology of producing corn flour all is with the direct abrasive dust of iblet, or abrasive dust behind the embryo is taken off in the corn peeling.The smell bad of the corn flour that these two kinds of methods are produced, sometimes even be difficult to swallow.Someone uses the ripe product of expanded mechanism in corn flour is made after, pulverize and process corn flour, this practice operation is loaded down with trivial details, and power consumption is high, is difficult for applying.
Summary of the invention
The objective of the invention is provides the production method of good, the easy and simple to handle corn flour of a kind of product mouthfeel to the problems referred to above.
For achieving the above object, the present invention has adopted following technical proposal: a kind of production method of corn flour, it comprises the steps:
Step 1: iblet is immersed in 90 ℃-95 ℃ of water temperatures, in the water of pH value 5.6-5.9, reaches 35%-45% until water content;
Step 2: the water temperature of soaked in water is reduced to 30 ℃-40 ℃, add lactic acid bacteria or saccharomycete;
Step 3: when the pH value of soaked in water drops to 5.0, add carbohydrase and zytase;
Step 4: when the pH value of soaked in water drops to 4.5, wash iblet, reach the 6.5-7.5 scope until the pH value of iblet with clear water washing or with little alkaline soak;
Step 5: pull iblet out, process the corn powder of water content at 2%-5%.
In the production method of above-mentioned corn flour, in step 1,, make the pH value of soaked in water reach 5.6-5.9 through adding in lactic acid, adipic acid, potassium citrate, sodium dihydrogen phosphate, the citric acid one or more.
In the production method of above-mentioned corn flour; In step 4, the used alkali preparation of little buck of adding is one or more in NaOH, potash, sodium carbonate, SODIUM PERCARBONATE, tertiary sodium phosphate, sodium pyrophosphate, sodium phosphate trimer, the sodium hydrogen phosphate.
In the production method of above-mentioned corn flour, in step 2, further add a amylase.
In the production method of above-mentioned corn flour, in step 5, pull iblet and defibrination out, the starch adhesive of getting 80 mesh sieves dehydrates, and processes the corn powder of water content at 2%-5%.
In the production method of above-mentioned corn flour, in step 5, pull iblet out after, iblet dried or dry to water content be lower than 18%, then with the iblet peeling, take off embryo, again iblet is dried to water content 2%-5%, at last with the iblet abrasive dust.
In the production method of above-mentioned corn flour, in step 5, pull iblet out after, iblet dried or dry to water content be lower than 18%, then with the iblet peeling, take off embryo, again with the iblet abrasive dust, then corn flour is dried to water content 2%-5%.
The present invention adds lactic acid bacteria or saccharomycete when soaked in water temperature drop to 30 ℃-40 ℃, through lactic acid bacteria or saccharomycete acidogenic fermentation, thereby make pH value quickly fall to 5.0.And drop at 4.5 o'clock at pH value, and adding carbohydrase and zytase, thereby make the endoplasm structure of corn flour that variation take place, the product mouthfeel is good, and corn is fragrant outstanding, and gluten and elasticity have obtained reinforcement.And the production method of corn flour of the present invention is easy and simple to handle, and compliance is strong, and it is low to consume energy, and is convenient to mechanization and uses.
The specific embodiment
The production method of the corn flour that first embodiment of the invention provides comprises the steps:
Step 1: iblet is immersed in 90 ℃-95 ℃ of water temperatures, in the water of pH value 5.6-5.9, reaches 35%-45% until water content.Particularly, in soaking container, add a certain amount of 90 ℃-95 ℃ hot water, and add food acids and its esters, make the pH value of water arrive the 5.6-5.9 scope.Used corn is one or more in solids type, horse flute profile, half horse flute profile, the opaque type.Food acids that adds and its esters are one or more in lactic acid, adipic acid, potassium citrate, sodium dihydrogen phosphate, the citric acid.
Step 2: the water temperature of soaked in water is reduced to 30 ℃-40 ℃, add lactic acid bacteria or saccharomycete.Because lactic acid bacteria or saccharomycete can acidogenic fermentations, so the pH value of soaked in water can continue to descend.Preferably, in this step, can also add a amylase of suitable middle temperature.
Step 3: when the pH value of soaked in water drops to 5.0, add carbohydrase and zytase.
Step 4: when the pH value of soaked in water drops to 4.5, wash iblet, reach the 6.5-7.5 scope until the pH value of iblet with clear water washing or with little alkaline soak.Preferably, the used alkali preparation of little buck of adding is one or more in NaOH, potash, sodium carbonate, SODIUM PERCARBONATE, tertiary sodium phosphate, sodium pyrophosphate, sodium phosphate trimer, the sodium hydrogen phosphate.
Step 5: pull iblet and defibrination out, the starch adhesive of getting 80 mesh sieves dehydrates, and processes the corn powder of water content at 2%-5%.
The production method of the corn flour that second embodiment of the invention provides and first embodiment are basic identical; The difference part be, in step 5, pull iblet out after; Iblet dried or dry to water content be lower than 18%; Then iblet is removed the peel, taken off embryo, again iblet is dried to water content 2%-5%, at last with the iblet abrasive dust.
The production method of the corn flour that third embodiment of the invention provides and first embodiment are basic identical; The difference part be, in step 5, pull iblet out after; Iblet dried or dry to water content be lower than 18%; Then iblet is removed the peel, taken off embryo,, then corn flour is dried to water content 2%-5% again with the iblet abrasive dust.
The present invention adds lactic acid bacteria or saccharomycete when soaked in water temperature drop to 30 ℃-40 ℃, through lactic acid bacteria or saccharomycete acidogenic fermentation, thereby make pH value quickly fall to 5.0.And drop at 4.5 o'clock at pH value, and adding carbohydrase and zytase, thereby make the endoplasm structure of corn flour that variation take place, the product mouthfeel is good, and corn is fragrant outstanding, and gluten and elasticity have obtained reinforcement.And the production method of corn flour of the present invention is easy and simple to handle, and compliance is strong, and it is low to consume energy, and is convenient to mechanization and uses.
Specific embodiment described herein only is that the present invention's spirit is illustrated.Person of ordinary skill in the field of the present invention can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
Although this paper has used terms such as lactic acid bacteria, saccharomycete, carbohydrase, zytase, food acids morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present invention more easily; It all is contrary with spirit of the present invention being construed to any additional restriction to them.
