Abstract:
The aim of this article was to study degreasing of raw materials raw fish bone waste and animal waste.
A new method was developed, aimed at intensive extraction of fat with an additional absorber- delimonene, placed in water during high-temperature cooking of raw materials of animal origin. Delimonene is a widespread terpene hydrocarbon, and a primary component of orange peel oil (constitutes
up to 80–90%). Degreasing with the inclusion of de-limonene increases the degree of hydrolysis of
collagen from animal raw materials, which intensifies the extraction of fat from the processed raw
materials. High-temperature cooking promotes the breakdown of triglycerides into free fatty acids,
which further break down into low molecular weight products. At the end of the heat the temperature
of the heating plates is 70-90°C, the pressure inside the boiler is 1.6,-2.4 kPa, the duration is 60-100
minutes treatment of the raw material, a two-phase system was obtained: dry fat greaves and fat.
Fat was sucked off by pumps connected to digesters, and greasy greaves were sent for degreasing by
pressing. The method produced broth, fat, and feed.
