Abstract

The invention discloses a method for preparing crude fish oil, collagen peptide and hydroxyapatite by using scaled fish skin. The method comprises the following steps: firstly, carrying out low-temperature oil extraction and once glue extraction on the scaled fish skin, obtaining an oil phase 1, a glue solution 1 and solid residue 1 after carrying out three-phase separation; carrying out secondary high-temperature glue extraction on the solid residue 1, obtaining an oil phase 2, a glue solution 2 and solid residue 2 after carrying out three-phase separation; mixing the oil phases 1 and 2 and then carrying out secondary three-phase centrifugal separation to obtain the crude fish oil; carrying out high-temperature calcining on the solid residue 2 to obtain the hydroxyapatite; merging the glue solutions 1 and 2 and then carrying out enzymolysis, decoloring, membrane filtration concentration, freezing and drying through alkaline protease to obtain the collagen peptide. The hydroxyapatite is high in biological utilization rate, and can be used in high-calcium biological products; the collagen peptide is good in sensory index and high in biological activity; and the crude fish oil accords with the standard of SC-T3502-2000 first-level crude fish oil. The method is different from the traditional method of separately treating scales and fish skin, and has the advantages of comprehensive utilization of raw materials, low processing cost and strong process applicability.

Description

technical field [0001] The invention relates to the technical field of a method for simultaneously extracting multiple effective substances from biological raw materials, in particular to a method for preparing crude fish oil, collagen peptide and calcium hydroxyphosphate from scaled fish skin. Background technique [0002] my country has vast waters and abundant fish resources, and the number of freshwater fish breeding ranks first in the world, providing good, cheap and continuous raw materials for the comprehensive utilization of freshwater fish in my country. The modern fish processing industry mainly revolves around the production of skinless fish fillets and surimi, and the waste generated, such as skin, scales, bones, fins, etc., despite their high nutritional value, only a small amount is used to produce feed. Some are discarded, causing environmental pollution. [0003] Fish oil is a natural functional health food. The phospholipids contained in fish oil are an ind...
