Method for preparing disinfected-decolorized fish-squamosum organic acid calcium and non-denatured collagen

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...

On the other hand, my country is the largest aquaculture country in the world. There are currently 8,287 aquatic product processing enterprises, with an annual processing capacity of 13.06 million tons and a total annual fish waste of more than 2 million tons, especially freshwater fish processing. Fish scales and bones account for 50-70%, causing great environmental pressure
