Abstract

The invention discloses an animal bone calcium extraction method and bone gla protein made thereby. The animal bone calcium extraction method includes the steps of triple defatting, double centrifuging, fermenting, and compound protease hydrolysis. Fat in the bone powder made by the defatting process is substantially removed, so that fat content of calcium agent obtained by enzymolysis is smaller than 0.1%. The bone gla protein is safer and healthier for consumers with cardiovascular diseases but causes no increase in financial burden.

Description

technical field [0001] The invention relates to a bone calcium extraction process and belongs to the field of food processing. Background technique [0002] With the aging of society, the prevalence of osteoporosis ranks first among metabolic bone diseases in western countries. The pain that osteoporosis brings to patients and families is self-evident. According to statistics, there are currently more than 100 million osteoporosis patients in China, and it is estimated that the number will increase to 210 million by 2050. Factors causing calcium deficiency in more and more people: Accelerated pace of life and work, high work pressure and irregular life, not paying attention to the reasonable collocation of dietary structure, those with a daily calcium intake of less than 600 mg can be considered as calcium intake Insufficient calcium in the body can easily lead to lack of calcium in the body; some middle-aged people are stressed at work, lack self-care awareness, and do no...
