Abstract
The invention discloses inspection methods of wheat whiteness and wheat gluten. The inspection methods include an inspection method of the wheat whiteness and an inspection method of the wheat gluten. The inspection method of the wheat whiteness includes the steps of 1) powdering wheat and 2) inspecting the whiteness; the inspection method of the wheat gluten includes the steps of 1) powdering the wheat 2), washing by a machine, 3) washing by hands and 4) measuring the gluten index. The inspection methods of the wheat whiteness and the wheat gluten have simple processes, are easy to implement, can be used for guiding wheat distribution of the mass production of wheat flour and quality control of the mass production of the wheat flour, and simultaneously can also be used for guiding wheat procurement.
Description
Technical field
The invention belongs to the processing of farm products field, be specifically related to the method for inspection of a grow wheat, the method for inspection of especially a kind of wheat whiteness and gluten.
Background technology
The check of wheat generally includes the indexs such as moisture, color and luster, smell, color of the leather, hardness, impurity, unsound grain, unit weight.And for the flour processing industry, often need to determine and join Meccah work according to the whiteness of wheat and gluten quality, thereby guarantee the whiteness of flour and the quality of gluten, but also lack at present a kind of whiteness and gluten that effectively from the method for wheat Direct Test wheat whiteness and gluten, judges flour in industry, therefore need frequently to detect whiteness and the gluten quality of flour in production run, and joined wheat.
Summary of the invention
The object of the present invention is to provide the method for inspection of a kind of wheat whiteness and gluten, by the method, can instruct accurately workshop to be joined wheat and processing.
In order to realize the present invention, the method for inspection of a kind of wheat whiteness of the present invention and gluten, it comprises the method for inspection of wheat whiteness and the method for inspection of wheat gluten, the technical scheme that they are taked is as follows:
A kind of method of inspection of wheat whiteness, it comprises the following steps:
1) powder wheat: get 100 grams and put into the high-speed small-size comminutor of 25000 rev/mins through the wheat of cleaning, open comminutor 2 minutes, wheat flour is broken into to the powdery of particle diameter≤0.15mm, then granular material is all proceeded on the electronic screen cloth of testing dressing sieve CB30 and sieve continuously 10 minutes, the powder class part of material is separated fully with the wheat bran part, remove the wheat bran part.
2) check whiteness: by step 1), screen underflow flour is partly got the pressure surface box that about 15g puts into the whiteness instrument, with the pressure surface piece, flour is compressed and makes the face piece, and keep the surfacing of face piece smooth, then the face piece is put on the measuring seat of whiteness instrument, can measure the whiteness of this wheat.
A kind of method of inspection of wheat whiteness, according to the limited number of time evidence: the whiteness of wheat and this wheat processing go out between the whiteness of flour generally to differ 10 whiteness values, as: the whiteness of the wheat of measuring according to above method is 67.0, the whiteness of the flour gone out by this wheat processing so is exactly 77.0, we just can shift to an earlier date anticipation according to the whiteness of advancing factory's wheat and go out the whiteness that this wheat processing goes out flour like this, thereby instruct workshop accurately to join wheat.
A kind of method of inspection of wheat gluten, it comprises the following steps:
1) powder wheat: get 100 grams and put into the high-speed small-size comminutor of 25000 rev/mins through the wheat of cleaning, open comminutor 2 minutes, wheat flour is broken into to the powdery of particle diameter≤0.15mm, then granular material is proceeded on the electronic screen cloth of testing dressing sieve CB30 and sieve continuously 10 minutes, the powder class part of material is separated fully with the wheat bran part, remove the wheat bran part;
2) flour machine washing: by step 1) is respectively got 10g and is respectively charged in two 200 purpose glutens washing cups with gluten washing instrument washing 2 minutes, then is replaced with the washing 3 minutes on gluten washing instrument of 26 order glutens washing cups;
3) hand washing: will be through step 2) the final thing of secondary washing is that dough takes out, and then the artificial hand washing is 2 minutes, obtains gluten after washing away wheat bran;
4) gluten survey gluten index: by step 3) is inserted in the gluten index analyzer, set 3000 rev/mins of revolutions, 2 minutes time, open the gluten indexer gluten is dried, again gluten is put on balance to the content that weighs up wet gluten, be the gluten quantity of this wheat.
The method of inspection of above-mentioned a kind of wheat gluten, according to the limited number of time evidence: the gluten of wheat and this wheat processing go out between the gluten of flour generally to differ 2 gluten qualities, the gluten of measuring in order to upper method is 30%, the gluten of the flour gone out by this wheat processing so is exactly 32%, so just can judge the quality and quantity that this wheat processing goes out the flour gluten according to the gluten that advances factory's wheat, thereby instruct workshop accurately to join wheat.
Above-mentioned high-speed small-size comminutor, whiteness instrument gluten washing cup, gluten washing instrument, gluten index analyzer are common apparatus in industry, instrument.
The method of inspection of a kind of wheat whiteness of the present invention and gluten, the process of check wheat whiteness and gluten is simple, easily realization; Can be used to refer to the wheat of joining of guide face powder production in enormous quantities fully, and the quality control of flour production in enormous quantities; Also can be used for instructing the wheat buying simultaneously.
Embodiment
Below in conjunction with embodiment, the present invention is further elaborated respectively.
