FISH GELATINE THERMAL TREATMENT METHOD Russian patent published in 2019 - IPC C09H1/00 C09H5/00 

FIELD: technological processes.

SUBSTANCE: invention relates to food and medical industries and can be used in fish gelatine thermal treatment for improvement of its quality and safety. Method involves thermal treatment of fish gelatine by using sheet or powdered fish gelatine, which is in a dry aggregate state with residual moisture content of not more than 16 %, at temperature of 120–130 °C for 20–30 minutes with intensive air circulation with subsequent cooling of fish gelatine to ambient temperature.

EFFECT: enabling increase in the fish gelatine solution dynamic viscosity index, increase in the fish gelatine microbiological safety level.
