METHOD FOR PRODUCING COLLAGEN FROM THE SCALES OF THE CARASSIUS CARASSIUS JACUTICUS CARP Russian patent published in 2023 - IPC A23L29/281 

FIELD: pisciculture.

SUBSTANCE: invention can be used for recycling collagen-containing waste scales of the Carassius carassius jacuticus carp. Method for producing collagen from the scales of the Carassius carassius jacuticus carp involves the stages of receiving the scales of the Carassius carassius jacuticus carp, washing under running water at a temperature of 10 °C for 5 to 10 minutes, drying for 1 hour to 55 °C to a residual moisture content of 5 to 7% in an infrared drier, and crushing the dried scales of the Carassius carassius jacuticus carp in a mixer to a particle size of the scales of 0.3 mm. The crushed mass of the scales of the Carassius carassius jacuticus carp is then hydrolysed with trisodium citrate at a pH of 7 to 7.5 and a temperature of 37 °C. The resulting mass of collagen made of the scales of the Carassius carassius jacuticus carp is homogenised and packed in a polyethylene container, then stored for up to 6 months at a temperature from 0 to +5 °C.

EFFECT: production of native collagen.
