The same method, preceded by soaking in hot water to make
the matrix swell, was also applied in exhaustive extraction of mineral
oil from dry pasta samples. As an alternative, pressurised liquid
extraction (PLE) has been recently proposed for complete
extraction of mineral oil from dry pasta and grain cereals (Moret
et al., 2014), and later applied for mineral oil hydrocarbon (MOH)
determination in dry pasta stored in different packaging materials
over its shelf life
