A cell hydrolysate composition, the composition comprising substantially all protein polypeptides and/or polypeptide fragments derived substantially from all the proteins in a cell from an in vitro cell culture.

The invention relates to a composition of peptides having an aminogram in which: glycine, hydroxyproline and proline are in molar quantities such that the ratio of each quantity to the sum of the molar quantities of the amino acids in the composition is comprised between 20.0% and 24.5%, between 6.0% and 12.0% and between 10.6% and 14.6%, respectively; the peptide composition comprising a quantity of peptides with a molecular weight lower than 1400 Da such that the ratio of said quantity to the quantity of peptides in the composition is less than 40%; the molecular weight and the quantity of peptides in the composition being determined by exclusion chromatography. The invention likewise relates to such a composition to be used as a drug. The invention further relates to such a composition to be used as a food supplement.

A food product ingredient formed from a keratinous protein-containing material, e.g, feathers, and methods of making the same. The methods include cleaning the keratinous protein-containing material, combining the keratinous protein-containing material with a cereal bran to form a mixture, and hydrolyzing the mixture to form the food product ingredient. Optionally, of the keratinous protein-containing material is cleaned and/or frozen within 5 hours of collection. The methods generate fewer unpleasant odors, and food product ingredients produced by the method can similarly benefit. The food product ingredient may be incorporated into a food product, such as a pet food product.

A compound composition for improving bone health and preparation and application thereof are provided. The compound composition is prepared by combining a traditional Chinese medicine extract with chicken cartilage collagen, magnesium, vitamin K2 and vitamin D3. The compound composition overcomes the food safety risk of the existing osteoporosis preventive drugs by adding the traditional Chinese medicine extract for improving osteoporosis and promoting bone health. And the compound composition disclosed can be used as a dietary supplement or health food raw material for preventing or treating osteoporosis. Therefore, the compound composition disclosed is suitable for promotion and application.

A method for drying moist jellyfish matter is provided. Jellyfish matter undergoes a controlled drying process until the jellyfish matter comprises a dried flake or mass.

The invention relates to a composition of peptides having an aminogram in which: glycine, hydroxyproline and proline are in molar quantities such that the ratio of each quantity to the sum of the molar quantities of the amino acids in the composition is comprised between 20.0% and 24.5%, between 6.0% and 12.0% and between 10.6% and 14.6%, respectively; the peptide composition comprising a quantity of peptides with a molecular weight lower than 1400 Da such that the ratio of said quantity to the quantity of peptides in the composition is less than 40%; the molecular weight and the quantity of peptides in the composition being determined by exclusion chromatography. The invention likewise relates to such a composition to be used as a drug. The invention further relates to such a composition to be used as a food supplement.

The present invention relates to a method for producing bone gelatine having an isoelectric point of less than 6, comprising the following steps: a) providing bones of vertebrates; b) mechanically crushing the bones to a particle size of less than 1 500 μm, preferably less than 500 μm, more preferably less than 300 μm; c) extracting the crushed bones using an aqueous medium at a temperature of from 100 to 140° C., preferably from 120 to 130° C., for a period of from 0.5 to 10 min, preferably 1 to 5 min, more preferably 1 to 3 min; d) separating off the aqueous gelatine solution from the crushed bones; and e) drying the aqueous gelatine solution in order to obtain the bone gelatine having an isoelectric point of less than 6, wherein the method does not comprise liming of the bones with a base, and wherein the bones provided in step a) have not undergone liming. The invention further relates to bone gelatine having an isoelectric point of less than 6, produced by this method.
