  • How to extract black cumin seed oil?
  • Black cumin seed oil can be extracted by press (hot or cold press-ing methods) or solvent. Solvent extraction and hot press give higher oil extraction yield, but the obtained oil has to be refined due to higher impurities (Kiralan et al., 2014). Oil extracted by cold press
  • What is black cumin (Nigella sativa) seed oil?
  • Black cumin (Nigella sativa) seed (BS) oil has received much interest in the food and pharmaceutical industries due to its valuable nutritional properties, but this oil has low oxidative stability.
  • Does cold press & supercritical fluid extraction affect black cumin seed oil quality?
  • To date, comparative studies on the effect of solvent, cold press, and supercritical fluid extraction (SEF) on the quality attributes of black cumin seed oil are scarce. In addition, little information is available in the literature about black cumin seed oils extracted with SFE.
  • How many phenolic compounds are present in black cumin seed oil?
  • The total phenolics for the black cumin seed oils obtained via cold press, solvent, and SEF were 48.90, 6.37, and 53.61 µg/g, respectively. Observed that the amount of total phenolic compounds was higher in oil extracted by SFE and cold press. Based on these results, several characteristic phenolic compounds may be formed during SFE and cold press.
  • Do black cumin seeds melt?
  • Oils extracted with cold press, solvent, and SFE all had melting peaks within the low-melting region. Extraction methods affected black cumin seed oils melting behavior. An oil with a large low-temperature peak indicates relatively unsaturated conditions.
  • Why is cold pressed black cumin oil so popular?
  • Among these techniques, the cold pressing method is popular due to consumers’ desire for natural and healthy foods. Cold pressed black cumin oils (CPBCO) contain high levels of polyunsaturated fatty acids (~ 60% of total fatty acids), followed by monounsaturated fatty acids (~ 24% of total fatty acids).
