preparation example Construction

[0032] Such as Figure 1 to Figure 5 Shown, the preparation method of a kind of collagen peptide of the present invention comprises the following steps:

[0033] S1: Preliminary cleaning of fish skin, donkey skin and chicken feet, wherein the mass ratio of fish skin, donkey skin and chicken feet is 2:1.5:3, and then put fish skin, donkey skin and chicken feet into sodium carbonate solution Carry out degreasing treatment, wherein the concentration of sodium carbonate solution is 0.35g / L, and the temperature of sodium carbonate solution is maintained at 35-55°C;

[0034] S2: Put the degreased fish skin, donkey skin and chicken feet into the rinsing barrel 8 in the rinsing device, then fill the water tank 5 with 0.9g / L NaCl aqueous solution and distilled water successively, and the temperature inside the water tank 5 Keep it at 32-45°C, start the driving motor fixedly connected to the threaded rod 18, and the fish skin, donkey skin and chicken feet after rinsing will be discharg...

Embodiment approach

[0041] As an embodiment of the present invention, the movable sealing mechanism includes a movable pressing rod 9, a bobbin 26 and a driven circular gear 27; the movable pressing rod 9 is a V-shaped structure; The fold is hinged at one end of the mounting plate 30 through a torsion spring, and the other end of the mounting plate 30 is fixedly installed on the outer wall of the rinse barrel 8; when the torsion spring is in a natural state, the movable pressure rod 9 will press the sealing plate 28 on the rinse plate. The bottom of the barrel 8; the movable pressure rod 9 is fixedly connected to one end of the stay cord away from the end of the rinse barrel 8, and the other end of the stay cord passes through the side wall of the rinse barrel 8 and is fixedly connected to the edge of the bobbin 26; The center position of the bobbin 26 is fixedly connected with one rotating shaft of the driven circular gear 27, and the other rotating shaft of the driven circular gear 27 is fixedly...

Abstract

The invention belongs to the technical field of collagen peptide production, and particularly relates to a preparation method of collagen peptide. The preparation method comprises the following steps:S1: preliminarily cleaning fish skin, donkey skin and chicken feet in a mass ratio of 2: 1.5: 3, and degreasing the fish skin, donkey skin and chicken feet in a sodium carbonate solution; by arranging the rotating stirring rod in the rinsing barrel, the stirring effect can be achieved, the rinsing effect is improved, the amount of water added into the rinsing barrel is increased from small to large, then raw materials such as fish skin can be scrubbed in the rinsing barrel when the water amount is small, then large-range dispersion is conducted when the water amount is increased, impurities and a sodium carbonate solution on the surface of the raw material are rinsed away, the cleaning and rinsing effects are improved, the rinsed raw material can be dewatered in the metal net cylinder, redundant moisture on the surface of the raw material is removed, and subsequent operation is facilitated.

Description

technical field [0001] The invention belongs to the technical field of collagen peptide production, in particular to a preparation method of collagen peptide. Background technique [0002] Collagen is an important functional polysaccharide protein, which is closely related to cell regeneration, differentiation, exercise, immunity, joint lubrication, blood pressure suppression, wound healing, aging and disease. Collagen peptide, the enzymatic hydrolysis product of collagen, is a natural biological product, which has many physiological activities of collagen and characteristics that collagen does not have. As a new functional protein ingredient, it has developed at home and abroad in recent years. Rapidly, it is widely used in functional food, health food, cosmetics and pharmaceuticals because of its remarkable physiological activity. [0003] In the prior art, when preparing collagen peptides, most of the protein-rich parts such as animal skins or bones are hydrolyzed and en...
