Fermented sauced bone meal and preparation method thereof

The invention discloses fermented sauced bone meal and a preparation method thereof. The fermented sauced bone meal is prepared by adopting a way of fermenting after enzymolysis. Livestock and poultry bone protein and polysaccharide are degraded by adopting mixed bacteria and composite enzyme, so that bone calcium can be adequately separated, the bone calcium is interacted with amino acid to generate soluble calcium ammonium, the absorption and the utilization on the calcium can be promoted, and the content of soluble protein is increased. The developed fermented sauced bone meal is not only rich in nutrients, proteins, collagen polypeptide, amino acid, nucleotide, polysaccharide substances and minerals, but also full and strong in taste, thick in sauce fragrance, durable in fragrance, natural in flavor and easy to carry and store.
