浸提、微波和超声法的海芦笋植物盐提取效果差异研究OA

High salt content in lignified Salicornia europaea prevents its direct recycling or composting on land.The extraction efficiency of plant salt from Salicornia europaea using maceration,microwave-assisted,and ultrasonic-assisted methods were compared to determine the optimal extraction process.The results showed that,during maceration,extraction temperature,solid-to-liquid ratio,and extraction time all had significant effects on the extraction of plant salt,with the optimal conditions being an extraction temperature of 60℃,a solid-to-liquid ratio of 1∶24(g/mL),and an extraction time of 0.5 h.For microwave-assisted extraction,the solid-to-liquid ratio had the greatest effect,while power and time exhibited interactions;the optimal conditions were a solid-to-liquid ratio of 1∶32(g/mL),640 W,and 10 min.For ultrasonic-assisted extraction,the optimal conditions were a solid-to-liquid ratio of 1∶24(g/mL),an extraction time of 5 min,and an extraction temperature of 40℃,under which none of the three factors showed a significant effect on the extraction yield.Refined salt yields were similar across all three methods;crude salt yields varied significantly due to the presence of organic matter.Considering operational convenience,time efficiency,and crude salt yield,ultrasonic-assisted extraction was identified as the optimal method.
