Problems solved by technology

However, because cottonseed meal contains toxic component gossypol, it will have adverse effects on the growth, development and reproduction of the organism, limiting its consumption as a protein source, thus making this precious resource unable to be fully utilized. Most cottonseed meal is only used as fertilizer
At present, the utilization rate of cottonseed meal in my country is less than 15%, and at the same time, the protein source in my country is seriously insufficient. Therefore, effective detoxification of cottonseed meal is required to make full use of cottonseed meal protein.

Embodiment 1

[0066] Embodiment 1: (without adding distiller's grains)

[0067] A soluble protein powder of distiller's grain cottonseed meal, which is made of the following raw materials in parts by weight (optimal value):

[0068] Raw material parts by weight

[0069] Cottonseed Meal 100

[0070] water 250

[0071] Ferrous sulfate (food grade) 1

[0072] Calcium hydroxide (food grade) 1.5

[0073] Alkaline protease 3

[0074] Compound Flavor Protease 2.9. (alkaline endoprotease 200,000 u / g, flavor protease 200,000 u / g)

[0075] A method for preparing distiller's grains cottonseed meal soluble protein powder, the preparation steps are:

[0076] (1) Mix cottonseed meal, ferrous sulfate and calcium hydroxide evenly, add water at a mass ratio of 0.8-1:1, soak for 28 or 29 or 30 or 31 or 32 minutes, and fumigate at 121°C and 0.14-0.18Mpa for 1.0 Or 2.0h, so that the cottonseed meal can be well detoxified.

[0077] (2) The fumigated cottonseed meal is refined with water at a mass ratio ...

Embodiment 2

[0081] Stir and mix 100g cottonseed meal, 60g distiller's grains, 1.0g ferrous sulfate, and 1.5g calcium hydroxide, add 240g water for refining, adjust the pH value of the mixed slurry to 8.0, 3.0g alkaline protease, and enzymatically hydrolyze 5.0 at 60°C h; then adjust the temperature of the slurry to 55°C, adjust the pH value to 7.0, add 2.0g of compound flavor protease, enzymatically hydrolyze at 55°C for 3.0h, and inactivate the enzyme at 85°C to obtain the enzymatic hydrolyzate, which is then spray-dried to obtain distiller's grains cottonseed Meal soluble protein powder.

[0082] Other implementation steps are the same as in Example 1.

Embodiment

[0084] Stir and mix 100g cottonseed meal, 60g distiller's grains, 1.0g ferrous sulfate, and 1.5g calcium hydroxide, add 150g water, soak for 30min, fumigate at 121°C and 0.15Mpa for 1.0h, add 160g water for refining, and adjust the mixing The pH value of the slurry is 8.0, 3.0g alkaline protease, 60°C enzymolysis for 5.0h; then adjust the temperature of the slurry to 55°C, adjust the pH value to 7.0, add 2.0g compound flavor protease, 55°C enzymolysis for 3.0h, After the enzyme is extinguished at 85°C, the enzymatic solution is obtained, which is spray-dried to obtain the soluble protein powder of distiller's grain cottonseed meal.

[0085] Other implementation steps are the same as in Example 1.

Abstract

The invention discloses a distiller's grain cottonseed meal soluble protein powder and a preparation method thereof, which is composed of a certain proportion of cottonseed meal, distiller's grains, water, ferrous sulfate, calcium hydroxide, alkaline protease and compound flavor protease, and the steps are: ( 1) Mix cottonseed meal, distiller's grains, ferrous sulfate and calcium hydroxide evenly, impregnate, fumigate at 121°C, 0.14-0.18Mpa, and detoxify cottonseed meal; (2) Add water to the fumigated cottonseed meal and distiller's grains for refining , have mixed slurry. (3) Adjust the pH value of the mixed slurry, add alkaline protease, and enzymatically hydrolyze; adjust the pH value of the slurry again, add compound flavor protease, enzymolyze, and inactivate the enzyme to obtain the enzymatic hydrolyzate; (4) Spray dry the enzymatically hydrolyzate : The spray flow rate is 20-30mL / min, the feed temperature is 36-41°C, and the air inlet temperature is 160-190°C. The distiller's grain cottonseed meal soluble protein powder prepared by this method is easy to digest, has good flavor and high solubility index.

Description

technical field [0001] The invention belongs to the technical field of food, and more specifically relates to a soluble protein powder of distiller's grains and cottonseed meal, and also relates to a preparation method of the soluble protein powder of distiller's grains and cottonseed meal. Background technique [0002] Distiller's grains, also known as red grains, distiller's grains, dregs, etc., are the residues left after brewing rice, wheat, sorghum, etc. Distiller's grains are rich in crude protein, crude fat, minerals and cellulose, which have high development value. Starch is mainly consumed in the process of grain wine making, and most of the protein remains in the distiller's grains; a certain amount of ethanol still remains in the distiller's grains after distillation. [0003] Cottonseed meal is a by-product of cottonseed oil extraction. The cake obtained from cottonseed oil extraction contains about 40% protein, and the amino acid types of protein are relatively...
