PROCESS FOR PRODUCING COMPOUNDS OF INTEREST FROM AT LEAST ONE MINERALIZED CONNECTIVE TISSUE, AND COMPOUNDS OF INTEREST DERIVED FROM THIS PRODUCTION PROCESS

摘要

The present invention relates to a process for producing compounds of interest from at least one mineralized connective tissue, and to said compounds of interest comprising at least collagen. The production process comprises a step of solid/liquid extraction in which said at least one mineralized connective tissue is mixed with an eluent suitable for extracting said compounds of interest from said at least one mineralized connective tissue to said eluent. This extraction step comprises successive operations of adjusting the pH of said eluent, separated by a time interval; which operations of adjusting the pH each comprise an addition of an acid to the mineralized connective tissue/eluent mixture in order to reduce the pH of said eluent to achieve a pH value of less than or equal to 5.5, preferably less than or equal to 4, preferably ranging from 2 to 4.
