Description
Technical field
The invention belongs to corn processing technology field, a kind of method for preparing cornstarch.
Background technology
Corn originates from South America, and then by Europe, incoming Asia, Africa, corn is in more than the 470 years cultivation history in China.
Corn is also known as chinese sorghum, and it is one of world's Three major grain crops, is important feedstuff again, single because it is dry ground crop
Production is high, yield potential is big, therefore consequence is accounted in agricultural production.Corn wet milling processing is the method using physics by jade
Each main component of rice seed separates the process for obtaining corresponding product.By this process can obtain five kinds mainly into
Point：Starch, plumule, soluble protein, skin slag (fiber), seitan (protein).Because the ratio of starch contained therein in corn is maximum, one
As contents on dry basis 70% or so, so traditionally starch is referred to as major product, and remaining product is byproduct.
Cornstarch (cornstarch) is also known as corn starch.Popular name maize powder.The white flaxen powder of micro-strip.Make
It is that raw material of industry use is the main channel that corn is consumed, corn is not only the king of feed, or purposes is most wide in cereal crops,
Can development is most, dosage the is maximum raw material of industry.Starch is produced by raw material of corn, it is optimal to can obtain chemical analysis, into
This minimum product, added value exceed tens times of corn initial value, are widely used in the industries such as papermaking, food, weaving, medicine.
It is existing make cornstarch immersion processing technology it is unreasonable, the cornstarch produced it is not fine enough, cause
The starch quality of plant is poor, and speed is slow, and efficiency is low.
The information for being disclosed in the background section is merely intended to understanding of the increase to the general background of the present invention, without answering
It has been the prior art well known to persons skilled in the art when being considered as recognizing or implying the information structure in any form.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of speed fast, efficiency high, and the starch produced is fine, quality
The preparation method of good cornstarch.
Technical scheme is as follows：
A kind of method for preparing cornstarch, comprises the following steps：
(1) soak：Corn is put into water and adds lactic acid and sulfurous acid solution, is soaked in water bath with thermostatic control, is soaked
It is dried after end；
(2) preliminary grinding：Corn is put into the mixer with blunt blade, appropriate water is added and is ground；
(3) recovery of embryo and skin；
(4) refine：Slurries are ground again；
(5) separation and cleaning of fiber；
(6) separation of starch and seitan；
(7) starch dehydrating.
Preferably, soak time is 45-55 hours in preparation method of the present invention, water bath with thermostatic control temperature is 48-
54℃；Drying temperature is 45-55 DEG C.
Preferably, in preparation method of the present invention lactic acid concn be 0.3-0.8%, sulfurous acid concentration 0.1-
0.5%.
Compared with prior art, the present invention has the advantages that：
The procedure of the present invention is reasonable, and speed is fast, efficiency high, and the starch produced is fine, quality is good.
