Abstract:
... Extraction of essential oil from Cuminum cyminum seeds using a combination of organic solvent with low boiling point and steam distillation was explored. The effect of different parameters, such as particle size (40, 60, 80mesh), temperature (°C) 10, 15, 20 and extraction time (3, 5, 8h), on the extraction yield was investigated using three-level orthogonal array design. The experimental results s ...
