To reduce the use of imported raw materials in the manufacture of greases, this paper proposes introducing poultry fat, which is a by-product of poultry farms.
Poultry fat is obtained by heating the internal and intestinal fat accumulated during the processing of poultry carcasses, i.e., waste that, for sanitary reasons, is not suitable for human consumption. In its composition, poultry fat contains the following fatty acids: oleic – 40.8 %, palmitic – 24.1 %, linoleic – 19.7 %, stearic – 7.5 %, palmitoleic-nova – 5.0 %, myristic – 1.0 %, etc. The acid number of poultry fat is 2.6 mg KOH/g; the saponification number is 194.2 mg KOH/g, iodine number, g I2/100 g, is 89.30.
