Sesame oil is usually extracted by means of mechanical screw-pressing. The conventional screw-pressing processes used for SO extraction generally include a previous seed roasting step. Although seed roasting can increase oil recovery, it may have deleterious effects on oil quality.
How to optimize a process for sesame oil extraction by screw-pressing?
Ma. Gabriela Bordón, Box-Behnken designs were used to optimize a process for sesame oil extraction by screw-pressing at low temperature (50 °C). Experimental designs included seed moisture content (SMC), pressing speed (PS), and restriction die (RD) as the main processing parameters.
What is a sesame seed?
Sesame ( Sesamum indicum L., Pedaliaceae) is a common oilseed crop cultivated in tropical and sub-tropical regions of the world. Sesame seeds have high economical and nutritional value mainly due to their high oil content (45–60%). The world’s sesame oil production was about 4,756,000 tons in 2013 (FAOSTAT 2015.
How many tons of sesame oil are there in the world?
The world’s sesame oil production was about 4,756,000 tons in 2013 (FAOSTAT 2015. FAO Statistics Division); India, Sudan, and China were the major producers. The oil is used mainly for edible purposes, as a salad dressing and to produce shortenings and margarine (Kochhar 2002; Rostami et al. 2014 ).
