Abstract
The aim of the study is to increase the yield of oil from black cumin seeds. The results of studies of the influence of technological parameters - temperature and duration of drying of black cumin seeds on indicators of the yield of oil, cake and moisture removal from seeds are presented. The optimal technological parameters of the influence of the preliminary heat treatment process on the indicators of the maximum oil yield, acid number, color, and oil moisture have been established. The variable parameters were the temperature from 80 to 130 °C and the duration of the heat treatment process from 5 to 60 minutes. The possibility of increasing the oil yield by 6,11% has been shown. For this, the drying process must be carried out at a temperature of 100 °C and a process duration of 15 minutes. At the same time, the degree of oil extraction increases from 59,13% to 75,24%, the acid number decreases to 2,98, humidity to 0,12%, and color to 40.
