Assessment of Quality and Efficiency of Cold-Pressed Oil from Selected Oilseeds

Popis výsledku v původním jazyce

In this present study, an oil press was used to process 200 g each of sesame, pumpkin, flax, milk thistle, hemp and cumin oilseeds in order to evaluate the amount of oil yield, seedcake, sediments and material losses (oil and sediments). Sesame produced the highest oil yield at 30.60 +/- 1.69%, followed by flax (27.73 +/- 0.52%), hemp (20.31 +/- 0.11%), milk thistle (14.46 +/- 0.51%) and pumpkin (13.37 +/- 0.35%). Cumin seeds produced the lowest oil yield at 3.46 +/- 0.15%. The percentage of sediments in the oil, seedcake and material losses for sesame were 5.15 +/- 0.09%, 60.99 +/- 0.04% and 3.27 +/- 1.56%. Sediments in the oil decreased over longer storage periods, thereby increasing the percentage oil yield. Pumpkin oil had the highest peroxide value at 18.45 +/- 0.53 meq O-2/kg oil, an acid value of 11.21 +/- 0.24 mg KOH/g oil, free fatty acid content of 5.60 +/- 0.12 mg KOH/g oil and iodine value of 14.49 +/- 0.16 g l/100 g. The univariate ANOVA of the quality parameters against the oilseed type was statistically significant (p-value < 0.05), except for the iodine value, which was not statistically significant (p-value > 0.05). Future studies should analyze the temperature generation, oil recovery efficiency, percentage of residual oil in the seedcake and specific energy consumption of different oilseeds processed using small-large scale presses.
