Embodiment 1

[0024] A kind of deep sea fish bone collagen protein powder, preparation method is as follows:

[0025] 1) Remove impurities and clean the deep-sea fish skin, add 4-6 times the amount of hydrochloric acid solution, heat to 35-45°C, stir for 2 hours, wash with water until neutral; add 10-12 times the amount of sodium hydroxide solution, heat Stir for 2 hours at 35-45°C, wash with water until neutral; the volume concentration of the hydrochloric acid solution is 0.5-2%. The concentration of sodium hydroxide solution is 1-50g / L.

[0026] 2) Add 2-10% fish skin protease to the protein extract obtained in step 2), keep the temperature at 45-55° C. for 5 hours, and pH 6.5-7.5; then keep the temperature at 90° C. for 10 minutes; the protease It is prepared by mixing flavor protease and bromelain in a mass ratio of 1:2.

[0027] 3) Use a centrifuge to remove solid residues from the enzymatic hydrolyzed slurry; use an ultrafiltration membrane with a molecular weight of 1000Da to 8000...

Embodiment 2

[0030] A deep-sea protein powder prepared according to the following components:

[0031] 20 parts of deep-sea fish skin collagen powder, 20 parts of chicken ball bone collagen powder, 40 parts of water-soluble dietary fiber, 6 parts of chondroitin sulfate, 6 parts of calcium gluconate, 15 parts of calcium hydroxyphosphate, 40 parts of pea protein powder.

[0032] The specific steps of the preparation method are as follows:

[0033] (1) After weighing each component according to the amount, add it to warm water for soaking;

[0034] (2) Grinding the soaked mixture into a slurry;

[0035] (3) The slurry mixture is homogenized, the homogenization pressure is 20-23MPa, and the homogenization temperature is between 55-65°C;

[0036] (4) The air inlet temperature is controlled at 130-140°C, the outlet air temperature is 85-90°C, and the atomization degree is 70-80%.

Embodiment 3

Abstract

The present invention relates to deep sea protein powder. The deep sea protein powder is prepared from the following components: 10-20 parts of deep sea fish skin collagen powder, 10-20 parts of chicken ball bone collagen powder, 20-40 parts of water soluble dietary fibers, 4-6 parts of chondroitin sulfate, 4-6 parts of calcium gluconate, 10-15 parts of calcium hydroxyphosphate, and 30-40 parts ofpea protein powder. The protein powder is free of any additives, balanced in nutrients, good in solubility, easy for digestion and absorption and high in protein content, and supplements collagen lacking in the elderly. A method for preparing collagen peptide can effectively utilize a fish processing by-product of fish bones to prepare the collagen, and is low in costs, good in impurity removal and concentration effects, and suitable for large-scale industrial production. The prepared collagen is free of odor.

Description

technical field [0001] The invention relates to the technical field of nutritious food and its preparation, in particular to a deep-sea protein powder and a preparation method thereof. Background technique [0002] Protein is the main substance that constitutes the tissues and organs of the human body, and plays a very important role in the life activities of the human body. It is necessary to maintain and repair the body and cell growth. It not only affects the growth of body tissues, but also participates in the production of hormones, the maintenance of immune function, the transport of other nutrients and oxygen, and the production of hemoglobin. In short, protein is one of the most important nutrients for good health. [0003] Collagen, also known as collagen, is a fibrous protein formed by intertwining three peptide chains. It is a glycoprotein that contains a large amount of glycine, proline, hydroxyproline and sugar. It is widely found in animal skin, bones, In tis...
