Embodiment 1

[0042]A method for comprehensively utilizing oily soybean meal, the steps are:

[0043] (1) Crushing and sifting: extract the oily soybean meal, pulverize it with a stainless steel pulverizer and pass through a 20-mesh standard sieve to obtain the oily soybean meal powder for later use.

[0044] (2) Soaking in water and protein extraction: Take 20kg of oily soybean meal powder, add water 5 times its mass, adjust the temperature of the mixture to 25°C, and stir for 1 hour to make the oily soybean meal powder fully absorb water and expand; under stirring, The pH of the mixed material is adjusted to 8.4, 8.5 or 8.6 with a 5% sodium hydroxide solution by mass percentage, and the stirring is continued for 1.5 hours to dissolve the protein of the oily soybean meal, and the water-extracted mixed material of the oily soybean meal after the protein is dissolved is obtained. The stirring speed of this step is controlled to be 115 rpm.

[0045] (3) Separation of pulp and residue: under ...

Embodiment 2

[0052] A method for comprehensively utilizing oily soybean meal, the steps are:

[0053] (1) Crushing and sifting: extract the oily soybean meal, pulverize it with a stainless steel pulverizer and pass through a 40-mesh standard sieve to obtain the oily soybean meal powder for later use.

[0054] (2) Soaking in water and protein extraction: take 523 kg of oily soybean meal powder, add water 6 times its mass, and stir at room temperature for 1 hour to fully absorb water and swell the oily soybean meal powder; 5% potassium hydroxide solution is used to adjust the pH of the mixed material to 8.9 or 9.0 or 9.1, and the stirring is continued for 1 hour to dissolve the oily bean protein to obtain the water-extracted mixed material of oily soybean meal after the protein is dissolved. The stirring speed of this step is controlled to be 125 rpm.

[0055] (3) Separation of pulp and residue: under the condition of continuous stirring, the oily soybean meal water extraction mixture obtai...

Embodiment 3

[0062] A method for comprehensively utilizing oily soybean meal, the steps are:

[0063] (1) Grinding and sieving: take oily bean leaching meal, pulverize it with a stainless steel pulverizer and sieve through a 20-mesh standard sieve to obtain oily bean meal powder for later use.

[0064](2) Soaking in water and protein extraction: Take 912 kg of oily soybean meal powder, add water 8 times its mass, and stir for 2 hours to make the oily soybean meal powder fully absorb water and swell; The sodium solution adjusts the pH of the mixed material to 7.9 or 8.0 or 8.1, and continues to stir for 2.5 hours to dissolve the protein of the oily soybean, and obtain the mixed material of the water-extracted oily soybean meal after the protein is dissolved. The stirring speed of this step is controlled to be 135 rpm.

[0065] (3) Separation of pulp and residue: under the condition of constant stirring, add the oily soybean meal water extraction mixture obtained in step (2) into the starch...

Abstract

The invention discloses a method for comprehensive utilization of cyperus esculentus meal. The method comprises the following steps of (1) performing crushing and screening: taking cyperus esculentus meal, and performing crushing with a stainless crushing machine to obtain cyperus esculentus meal powder; (2) adding water, performing soaking, enabling protein to dissolve, and obtaining a cyperus esculentus meal aqueous extract mixed material: adding water to the cyperus esculentus meal; (3) performing slurry and residue separation: under the condition of continuous stirring, adding the cyperus esculentus meal aqueous extract mixed material of which the protein is dissolved to a starch pulping machine, and performing slurry and residue separation so as to obtain cyperus esculentus slurry and cyperus esculentus residues; (4) performing separation and refining on the cyperus esculentus starch: enabling the cyperus esculentus slurry obtained by a centrifugal separation method to be separated; (5) preparing cyperus esculentus isolated protein: taking a cyperus esculentus solution in which starch is removed; (6) preparing a cyperus esculentus aqueous solubility component extract: concentrating the cyperus esculentus aqueous extract in which the starch and the protein are removed by a concentration method so as to obtain a cyperus esculentus meal concentrated solution; and (7) preparing cyperus esculentus dietary fibers. The method is easy to implement and simple and convenient to operate, raw materials are completely and comprehensively used, and main products are developed according to main components, and the cost is low, and the method can realize mechanized production.

Description

technical field [0001] The invention relates to the technical field of oily bean processing, and more specifically relates to a method for comprehensive utilization and deep processing of oily soybean meal. Background technique [0002] Sativus Baeck (Cyperus esculentus L.Var. Sativus Baeck), also known as tiger nuts, ginseng beans, tiger beans, iron water chestnuts, underground chestnuts and underground walnuts, belongs to Cyperaceae (Cyperaceae). The herb is one of the most nutritious nuts in tropical to temperate regions. Its origin is Africa and countries along the Mediterranean Sea, and it has a long history of planting. The oily bean is very adaptable. Our country introduced the cultivation of the oily bean from Bulgaria in 1960, and it was successfully introduced and cultivated in Xinjiang in 1964. At present, it is cultivated in Heilongjiang, Beijing, Hebei, Henan, Hubei, Hunan, Shaanxi, Shanxi and Shandong. , Sichuan and other provinces and cities have oily bean pl...
