Effect of ultrasound-assisted cold plasma pretreatment to obtain sea asparagus extract and its application in Italian salami

The effect of the glow discharge cold plasma pretreatment (CPT) was investigated on the ultrasound-assisted extraction (UAE) of phenolic compounds from sea asparagus Salicornia neei. The extract was applied in dry fermented sausage (Italian salami). Thermal extraction methods demand a long processing time, are highly energy-consuming and cause irreversible nutrient losses. It was found that CPT (discharge power of 14 W for 5 min) prior to UAE...
