The invention is applicable to the technical field of
collagen peptide production, and provides a technology for extracting
protein in a
collagen peptide production process. The technology comprises steps as follows: A, primary cooking is performed; B, primary
temperature and pressure maintenance is performed; C,
filtration for production of primary soup is performed; D, enzymolysis is performed;E, secondary cooking is performed; F, secondary
temperature and pressure maintenance is performed; G,
filtration for production of secondary soup is performed; H, a cooking pot is cleaned as follows:bones cooked in the cooking pot twice are cleaned, and then new bones are added; I,
tertiary cooking is performed as follows: the secondary soup in step G is delivered into the cooking pot in step H,the new bones is subjected to cooking,
temperature and pressure maintenance and
filtration by the aid of the secondary soup, the new bones are not submerged by the added secondary soup, clear water isrequired to be added and can submerge the new bones, and filtered soup is primary soup and then is delivered to the next procedure for enzymolysis; J, steps E-I are repeated, the bones are cooked effectively, and then the primary soup is subjected to enzymolysis for extraction of the
protein. Thereby, with the technology, the
protein can be extracted effectively, and the
processing quality of follow-up work can be guaranteed.
