Embodiment Construction

[0014] Concentration by weight is 100 grams of drinking water chlorine dioxide agent, add 1000 milliliters of water to dissolve and activate, after the mixed solution turns yellow-green, replenish water to 100000 milliliters (content 0.01%), add fish bones and degreasing scales of 3 mm in size 10 kg, continuously stir and soak at room temperature for 2 hours, repeat 1-2 times, wash with water 0-1 times, take the degree of odorless, and complete disinfection and decolorization. Sterilized decolorized fish scale bone solid, according to the solid-liquid ratio of 1:8, add the sterilized decolorized fish scale bone to the organic acid solution (such as lactic acid, citric acid, etc.) with a concentration of 15% by weight, and use focused ultrasonic waves to interrupt (or circulate) Treat for 10 to 15 hours, filter, separate solid and liquid to obtain crude collagen fish scale bone, and place the filtrate at 10°C for 6 to 12 hours to obtain organic acid calcium precipitate, filter, ...

Abstract

The invention provides a method for preparing disinfected-decolorized fish-squamosum organic acid calcium and non-denatured collagen. The method comprises the following steps: adding disinfected decolorized fish squamosum solids to 10 to 20 percent organic acid in a solid-liquid ratio of 1:5-10; using energy-gathering ultrasonic wave to treat the obtained product for 4 to 24 hours; performing filtration and solid-liquid separation to obtain a crude product of collagen fish squamosum; standing filtrate at 10 DEG C for 4 to 15 hours to obtain organic acid calcium precipitate; filtering and drying the obtained product to obtain a finished product of disinfected-decolorized fish-squamosum organic acid calcium; adding 0.5 to 1 percent organic acid and/or 0.1 to 1 percent acidproof protease solution to the crude product of fish squamosum collagen in a solid-liquid ratio of 1:5-10; using energy-gathering ultrasonic wave to treat the obtained product at 10 to 35 DEG C for 2 to 4 hours until the crude product of fish squamosum collagen dissolves in the solution; removing impurities; and drying filtrate to obtain non-denatured collagen. The method has the advantages of low production cost and capability of obtaining disinfected-decolorized fish-squamosum organic acid calcium and non-denatured collagen at a time.

Description

Technical field: [0001] The invention is related to the preparation method of calcium organic acid and non-denatured collagen protein of sterilized decolorized fish scale bone. Background technique: [0002] The bone calcium composition of fish scales is about 58%-62%, and the protein accounts for about 26%-55%. The bone calcium composition is closest to human bones. Its annual consumption reaches hundreds of thousands of tons. At present, the supply is in short supply. The protein components in fish scale bones are similar in structure to human collagen (the main components of skin, cartilage, etc.), and have weak antigenicity. They have excellent affinity with human skin and good biocompatibility. , immunity, joint lubrication, wound healing, etc. are closely related, and can be used as a tissue support, and have a major impact on cell and tissue repair. Moreover, it can induce platelet attachment, activate blood coagulation factors, stop bleeding, and participate in cel...
