Abstract

The invention relates to the technical field of fish processing, in particular to a fishbone nanomaterial and its preparation and application. The fishbone nanomaterial according to the invention has a particle size of 300-600nm, has a pore size inside, and has a porosity of 25%-50%. , the average pore size is >6.5nm, the shape is smooth and complete, the particle size is uniform, and the pore size is uniform. It is obtained from bulk freshwater fish bones through degreasing, two-step crushing and mild enzymatic hydrolysis with hydrophobic protease. The conditions of enzymatic hydrolysis are controlled during the preparation process. , the fishbone nanomaterial with good practicability can be obtained with the above structure, which can be used as a slow-release drug carrier and applied to medicine, food or cosmetics.

Description

technical field [0001] The invention relates to the technical field of fish processing, in particular to a fishbone nanomaterial and its preparation and application. Background technique [0002] Fish bone is formed by dense arrangement of collagen and hydroxyapatite, and is often used as food or feed. In recent years, with the development of nanotechnology, fish bones can also be made into nanoparticles or nano-microspheres with micropores, which can be used as slow-release carriers for active substances and expand the application range of fish bones. [0003] In the existing technology of using fish bones, fish bones are often prepared into fish bone powder and used as food additives. If it is necessary to prepare functional fish bone materials, the usual preparation method is a combination of physical and chemical methods. The use of physical pulverization often leads to the loss of fish bones. The particle size of the nanoparticles is not uniform, and the chemical metho...
