Abstract

A method is provided for producing intensified whole-cereal flour by means of pulsed electric fields in collaboration with ultrafine pulverization, which includes: (1) preparing bran, middling and flour by cleaning, modulating and milling cereal grains; (2) performing superfine pulverization on the bran and the middling and performing sieving; (3) preparing a suspension by using water and the sieved bran and middling, and stirring constantly; (4) adding polysaccharide colloids into the suspension, and adjusting the pH to 4.0; (5) performing high-voltage pulse treatment on the suspension to ensure stable flow of the suspension; (6) centrifuging the suspension to separate the supernatant, and drying the obtained precipitate and performing sieving to obtain the treated bran and middling; and (7) mixing the treated bran and middling with flour uniformly to obtain whole-cereal flour.

Dependent claims

A method for producing intensified whole-cereal flour by means of pulsed electric fields in collaboration with ultrafine pulverization, the method comprising:

(1) preparing bran, middling and flour by cleaning, modulating and milling cereal grains;
(2) performing superfine pulverization on the bran and the middling and performing sieving for standby use;
(3) preparing a 20-30% suspension by using water and the sieved bran and middling, and stirring constantly to keep the suspension uniform;
(4) adding polysaccharide colloids into the suspension, and adjusting the pH to 4.0-5.5, with the polysaccharide colloids added in an amount of 0.2-0.5‰ of the mass of the suspension;
(5) placing the suspension obtained in step (4) into a processing chamber of a washed high-voltage pulse processing device for high-voltage pulse treatment to ensure stable flow of the suspension;
(6) centrifuging the suspension after step (5) to separate a supernatant, and drying the resulting precipitates at 30-37° C. to a moisture content below 14% and performing sieving to obtain treated bran and middling;
and
(7) mixing the treated bran and middling obtained in step (6) with the flour obtained in step (1) to obtain the whole-cereal flour.
