Ascidian bioresources: common and variant chemical compositions and exploitation strategy- Examples of Halocynthia roretzi, Styela plicata, Ascidia sp. and Ciona intestinalis
(English)Manuscript (preprint) (Other academic)
Four ascidian species have been compared on chemical compositions. All animal tunics have rich carbohydrate contents, while all inner body tissues are richer in proteins. Cellulose is present almost exclusively in the tunics and more in the order Stolidobranchia, while more sulfated polysaccharides are present in Phlebobranchia species. Almost all proteins are collagens with a high essential amino acid index and high delicious amino acid content. All fractions also have high contents of good-quality fatty acids and trace minerals but low toxic element contents, with different sterols and glycosaminoglycans. Therefore, in addition to the present utilizations of tunics for cellulose production and of some species’ inner body tissues as human food, one should explore all species’ inner body tissues as human foods and all tunics as food or animal feed with the contained cellulose as dietary fiber. Collagens, sulfated polysaccharides, glycosaminoglycans, sterols and trace elements could be explored as byproducts.
