摘要:
The invention is related to production of high-bloom grade gelatin from the poultry tissues (chicken, turkey, duck, goose). The goal of the invention is to develop an environment friendly process ensuring low operating cost to manufacture colorless, odourless, high grade gelatin (over 100 bloom) in line with islamic requirements from the poultry tissues.
摘要:
A method for the denaturation of proteins and/or DNA present in products derived from animals or on the surface of an article, comprising treating the animal derived product or the surface of the article with a denaturing agent in an amount effective to denature the protein and/or DNA.
摘要:
The invention relates to a process for the preparation of a gelatine composition with increased gelling and solubility capacities, and to the composition obtained by such process. The process comprises an acid and/or alcaline treatment of pigskin, cattle skin or bones, the aqueous extraction of collagen followed by subsequent steps of filtration, purification, evaporation, cooling, drying and milling. The process includes the incorporation of organic acids and pH regulating salts and preferably neutral salts directly into the resulting gelatine solution before cooling, drying and milling steps.
摘要:
Described is a method for the preparation of a gelatin hydrolysate having a decreased endotoxin content, comprising the steps of incubating a solution of gelatin of gelatin hydrolysate at a temperature of 70 -125°C at a pH of 3.5or less for a time period of at least 15 minutes, and recovering the gelatin hydrolysate. Further a gelatin hydrolysate thus obtained is described.

摘要:
The process of the invention for the preparation of the gelatine consists in that the crumbled animal bones are subjected to the maceration process with the acid of the concentration of not higher than 34% at the time from 1 to 14 days, during the maceration or after its termination from the post-maceration lyes the calcium salts are sepatated, and the ossein produced in this way, after the remainder of the acid is removed, possibly with the addition of the alkaline substance, is subjected to at least once extraction with water of the temperature from 40 to 1200°C, possibly in the case of the production of the gelatine hydrolyzate, to the water extract of the gelatine the proteolytic enzym is added and next it is inactivated, then the water extract of the gelatine or the gelatine hydrolyzate is cleaned using the known methods, the extract is concentrated, possibly dried and milled. The process of the invention is characterized in that the fat is removed from the reaction environment at the time of the maceration process and/or the extraction and/or after the termination of the maceration process and/or the extraction by the separation of the water phase containing the gelatine and the fatty phase and possibly the solid phase.
摘要:
This invention relates to a method for purifying a gelatin solution obtained in a continuous process from raw material consisting of fresh defatted bone material from pig, cattle, sheep or chicken, which method comprises the steps of grinding the raw material, optionally with addition of water, mixing the ground raw material with more water to form a slurry, subjecting the slurry, in optional order, to an adjustment of the pH to 2.4-3.9 and to an adjustment of the temperature to 90-125°C and maintaining these conditions for a time of 90 s to 1020 s. The slurry is then separated into a liquid phase and a solid phase, the pH is adjusted to 6.0-7.0, floccules formed are separated and the solution is clarified by filtration. This invention further relates to a gelatin obtained according to this method.
