Abstract

The invention discloses a fish scale and fish skin collagen active peptide manufacturing technology and belongs to the field of biotechnology. The manufacturing technology comprises the following steps: (1), pre-processing fish scale and fish skin; (2), extracting collagen polypeptide through a method of combining acid extraction method and a heat extraction method, with the extraction yield over 95%; (3), purifying collagen polypeptide extract; (4), concentrating collagen polypeptide solution; (5), preparing collagen bioactive peptide solution through an enzymic method; (6), drying the solution to obtain a finished product of collagen bioactive peptide powder with the total nitrogen content higher than 14% and the relative molecular mass smaller than 10kD. In the technology, marine fish residual wastes are fully utilized, wastes are changed into valuable, and a new way of developing and utilizing sea residual wastes with high values is developed; a separation technology system integrating a centrifugal machine technology and an electrodialysis technology is established, and the purpose of separating excess acid and collagen bioactive peptide and recycling recovered acid is realized, so that the manufacturing cost and the cost of environmental protection are reduced remarkably; the produced collagen bioactive peptide is high in total nitrogen content, high in security, high in biological activity and low in average relative molecular mass.
