Major Seafood Processing Code Course 2015 - 2019 Technology. 9540105 Student Pham Viet Nam Supervisors 1. Assoc. Dr. Trang Si Trung 2. Assoc. Dr. Nguyen Van Hoa Institution Nha Trang University The novelties of the thesis 1. The data on the chemical composition of catfish by-products Pangasius hypophthalmus collected at Nam Viet Seafood Processing Company An Giang province was reported which can be used in further studies. 2. A process was presented to recover three value-added products including fish protein hydrolysate FPH hydroxyapatite HA and crude lipid from catfish by-products. Using alcalase the FPH had a DH of 35 with gt 70 MW of lt 1000 Da a nitrogen total of a lipid total of . Using both alcalase and lipase the FPH had a nitrogen total of a lipid total of and an acid amine total of mg g protein. The best conditions for the preparation of HA from the fishbone were reported. The prepared HA had a size of 50 70 nm a Ca P ratio of a surface area of m2 g a pore volume of m3 g a pore size of nm and an absence of heavy metals. This is a novel approach to obtain maximum components from .
