Do different technologies affect the extraction yield of pumpkin seeds?
Firstly, the effect of the different technologies on the extraction yield from pumpkin seeds was evaluated and then compared with that of the conventional method, as can be seen in Fig. 1. The extraction yields ranged from 9.86 to 35.57?g/100?g of dry weight pumpkin seeds.
How are pumpkin seeds extracted?
Extraction procedure All of the extractions were performed using ground pumpkin seeds (0.8 ¨C 2.0?mm) that were suspended at a 1:15 solid/liquid ratio. The obtained extracts were filtered on a paper filter under vacuum and the solvent evaporated to determine the extraction yield (w/w). 2.2.1. Conventional extraction (CE)
How is PSO extracted from pumpkin seeds?
PSO is generally extracted by expelling the oil from the seeds mechanically. Both hulled and hull-less pumpkin seeds could be used for oil production. The oil from the hull-less seeds is much easier to extract and more commonly processed.
What is pumpkin seed oil?
It is dichromatic, viscous oil that has been documented for its strong antioxidant activity (Stevenson et al. 2007). Moreover, pumpkin seed oil (PSO) has the most remarkable health benefits (Nishimura et al. 2014), and thus it requires effective extraction techniques in order to guarantee a high-quality PSO.
