PROCESS FOR PRODUCING GELATIN WITH BIOACTIVE PROPERTIES FROM MARINE GASTROPODS

摘要

The invention relates to a process for preparing gelatin, with bioactive properties, to be used in the pharmaceutical industry, from marine gastropods. According to the invention, the process consists of the following steps: pre-treating the soft tissue of rapanas for the removal of adherent materials and non-collagenous contaminants, extracting gelatin by chemical treatment with 1 ... 5% organic acid, at solution pH of 3...4, extraction time of 24 ... 48 h, while stirring, and by enzymatic treatment, respectively, with 1 ...3% solution of acetic or citric acid, in which pepsin was dissolved, in a mass ratio pepsin : dry tissue of 1: 10 ... 1 :30, while stirring for 24 ... 72h, at a temperature of 20 ... 25°C , after which the gelatin solutions are subjected to purification, resulting in conditioned gelatin, either in the form of powder or spongy foil, soluble in water, having a high protein content of over 80% and a low carbohydrate content of less than 8% and lipid content of less than 2%, respectively.
