Abstract

Plant nutrients extracted from sustainable sources, namely Alaria esculenta and Lemna minor , have been evaluated for their nutritional value in an attempt to identify their potential as protein-rich sources. The implementation of green technologies such as high-power ultrasound to extract nutrients from these alternative biomasses was studied and compared to more traditional techniques. Probe sonicators fared better than bath sonicators in extracting bioactive compounds while ultrasound assisted with enzymes was more efficient than conventional or alkali extraction methods. Lemna minor was found to have the greatest extraction yield of nutrients.
