protein, lipid, ash content in studied species of Lemna were analyzed. It’s flavor profile is neutral and fresh or dried duckweed blends well with other food ingredients. The trace metal content in water and aquatic plants was determined on an atomic absorption spectrometer (AAS) "A Analyst 800" - Perkin Elmer. Protein content spanned from 20% to 35%, fat from 4% to 7%, and starch from 4% to 10% per dry weight. Introducing Lemna Could a small, unremarkable-looking water plant be the answer? Protein content spanned from 20% to 35%, fat from 4% to 7%, and starch from 4% to 10% per dry weight. Also known as ‘water lentil’, Lemna has a protein content remarkably similar to soybean. The total protein content varied between 20 and 30% of the freeze-dry weight, the starch content between 10 and 20%, the fat content between 1 and 5%, and the fiber content was ~25%. For hundreds of years, Lemna has been used as a feed crop for small-scale farming operations in Asia and Africa . With a protein content of over 50% and a similar amino acid profile to that of soy, duckweed can produce eight to ten times more protein per acre than soy. The concentrations of metals in both L. minor and L. gibba and for all sites showed a downward trend: Mn>Fe> Zn>Cu>Ni>Cr>Pb>Cd. Due to high protein content, the harvested duckweed is a potential food source for human and animal feeds . Duckweeds have been consumed as human food since long. Lemna is a genus of free-floating aquatic plants referred to by the common name "duckweed." Since the 1970s, there have been dozens of university trials exploring the potential of Lemna as a feed ingredient for chickens, aquaculture, pigs, and cattle. Lemna minor: Basal diets of differing protein content (18-22%) with or without fresh duckweed ad libitum: Access to fresh duckweed increased feed intake and growth rate. Duckweed has a number of advantages as a protein source. Its protein content and amino acid profile are similar to soybean meal. They are morphologically divergent members of the arum family. Sharma et al. Based on its wastewater treatment potential, it is hypothesized that Lemna minor can also be used as a cost effective and technically feasible option for leachate treatment. It is relatively inexpensive to produce and requires less growing area and fewer inputs than other plant protein sources such as soybean products. These rapidly growing plants have found uses as a model system for studies in community ecology, basic plant biology, ecotoxicology, and production of biopharmaceuticals, and as a source of animal feeds for agriculture and aquaculture. (2016) reported that the protein content of Lemna minor was 39.75 ± 0.47% and that digestibility of this plant protein for rohu Labeo rohita and common carp Cyprinus carpio was high as determined by an in vitro digestibility study. Species of the duckweed genera, Spirodela, Landoltia, Lemna, Wolffiella and Wolffia were analysed for protein, fat, and starch contents as well as their amino acid and fatty acid distribution. Duckweed contains all nine of the essential amino acids giving it a protein profile similar to eggs. Lemna Protein Concentrate is derived from the leaves of duckweed, one of several rapidly-growing aquatic plants of the genus Lemna. Protein makes up over 45% of the pant’s dry weight and Its incredibly high protein content gave rise to another common name – ‘vegetable meatball’. It also grows astonishingly fast, forming thick, green blankets on the surface of water. The essential amino acid content was higher or close to the requirements of preschool-aged children according to standards of the World Health Organization.
