The present disclosure relates, according to some embodiments, to methods and systems for processing a high-concentration protein product from a microcrop (e.g., aquatic species, Lemna) and compositions thereof. According to some embodiments, the present disclosure relates to a method of processing a biomass comprising a microcrop (e.g., Lemna), where the method may include: blanching a first portion of the biomass in a blanching solution to form a wet protein concentrate； separating the first wet protein concentrate from a separated solution (e.g., using a screw press, using a vibratory screen)； and drying the first wet protein concentrate to form at least one of a first protein concentrate flake and a first protein concentrate granule. In some embodiments at least one of the first protein concentrate flake and the first protein concentrate granule may comprise at least 45% protein and a Protein Digestibility Corrected Amino Acid Score (PDCASS) value of at least 0.88. In some embodiments, the present disclosure relates to protein products and compositions derived from a microcrop (e.g., derived from Lemna).
