Embodiment 1

[0032] (1) Extraction process of fresh sea sweet potato collagen

[0033] (1) Mechanical dermabrasion: Weigh 500g of fresh Haitian melon and put it into the dermabrasion machine on the frosting turntable, and dermabrasion for 10 minutes;

[0034] (2) Enzymatic peeling: Haitian melons after mechanical peeling are washed and placed in 0.017Kat / g food-grade papain with a concentration of 1.3%, the ratio of solid to liquid (g / mL) is 1:1.5, and the temperature is 45 ℃, enzymatic hydrolysis for 0.6h, and the enzymatically hydrolyzed Haitian melons were cleaned with a soft brush;

[0035] (3) Enzyme-killing cleaning: enzymatically hydrolyze and peel the Haitian melon in 90°C hot water for 5 minutes to kill the enzyme, and after cooling to room temperature, remove the sediment, viscera, spouts and teeth, and clean it with tap water;

[0036] (4) Soak with 0.15% food-grade chlorine dioxide for 4 hours for decolorization;

[0037] (5) Beating: After the washed decolorized Haitian melo...

Embodiment 2

[0063] (1) Extraction process of frozen Haitian melon collagen

[0064] (1) Mechanical dermabrasion: Weigh 50kg of frozen Haitian melon, after natural thawing, put it into the dermabrasion machine with a frosted turntable, dermabrasion for 20 minutes, and remove 70-80% of the skin of Haitian melon;

[0065] (2) Enzymatic peeling: Haitian melon after mechanical peeling, washed, placed in 50L of 0.017Kat / g food-grade papain with a concentration of 1.3%, and kept at a temperature of 45°C, enzymatically hydrolyzed for 1 hour, and the Haitian melon after enzymolysis Clean with a brush cleaning machine;

[0066] (3) Enzyme-killing cleaning: enzymatically hydrolyze and peel the Haitian melon in hot water at 90°C for 10 minutes to kill the enzyme. After cooling to room temperature, remove the sediment, viscera, spouts and teeth, and clean it with tap water;

[0067] (4) Soak peeled Haitian melon with 50L of 0.20% food-grade chlorine dioxide for 4 hours for decolorization;

Abstract

The invention discloses an extraction method of acaudina molpadioidea collagen. The extraction method comprises the following steps: adopting fresh and frozen acaudina molpadioidea or dry acaudina molpadioidea as raw material; cleaning the raw material, decontaminating, combining, peeling, destaining, slicing, pulping, adjusting the liquid-solid ratio, adjusting pH, heating, hydrolyzing, crudely extracting, purifying, drying and the like; and extracting the acaudina molpadioidea collagen. By adopting the method, heavy metal pollution is removed before hydrolyzing; no strong acid or alkali is used in the hydrolyzing process; the operation is simple and convenient; the prepared collagen is high in purity and good in safety; the obtained collagen not only can be applied to food, cosmetics and the like, but also has wide application on the aspect of pharmacological action.

Description

technical field [0001] The invention relates to a method for extracting Haitian melon collagen, which belongs to the technical field of bioengineering. Background technique [0002] Haitian melon (Acaudina molpadioides Semper), commonly known as Haitian melon, sea eggplant, fragrant ginseng, etc., is an animal of the order Molpadida, the family Caudinidae, and the genus Acaudina, with a maximum body length of 400mm. It is 100-200mm, and it is mainly distributed in the seabed ooze from the tidal zone to the depth of 80 meters in the East China Sea. [0003] Studies have shown that Haitian melon is very rich in nutrients, rich in protein, polysaccharides, low in fat and amino acids, extremely high in calcium, zinc and iron, and also contains selenium, vitamin A, vitamin B6, vitamin E, etc. The crude protein content of sweet potato body wall accounts for 89.16% of the dry weight of Haitian melon, which is higher than the crude protein content of sea cucumber. The main componen...
