Abstract: 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 ?m, preferably less than 500 ?m, more preferably less than 300 ?m; 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.

Abstract: The present invention relates to a method for producing collagen peptides from bones, comprising the following steps: a) providing bones of vertebrates; b) mechanically crushing the bones to a particle size of less than 1 000 ?m, preferably less than 500 pm, more preferably less than 300 ?m, at a temperature of less than 70° C. during the crushing; c) heating the crushed bones in an aqueous suspension to a temperature of above 100° C., preferably above 120° C., more preferably above 130° C., for a period of from 1 to 30 min, preferably 2 to 10 min, more preferably 4 to 8 min; d) adding one or more proteases to the suspension in order to obtain an aqueous solution of collagen peptides; and e) separating off the aqueous solution of collagen peptides from the crushed bones, wherein the method does not comprise maceration of the bones with an acid or liming of the bones with a base, and wherein the bones provided in step a) have not undergone maceration or liming.

Abstract: In order to provide an improved powder coating process using gelatin particles for the production of coatings or shaped bodies based on gelatin, it is proposed that the gelatin particles are produced by drying an aqueous gelatin solution, wherein the gelatin does not pass through a gel state before or during the drying.

Abstract: The present invention relates to a coated detergent composition and a process of manufacturing thereof. More in detail the present invention refers to a coated detergent tablet wherein the coating is applied to the tablet by bringing a powder coating material in direct contact with the tablet and thereafter equalizing the powder particles in a way that a homogenous “fused” coating (film) layer is obtained.
