Sequential Extraction of Valuable Bio-Products from Snow Crab () Processing Discards Using Eco-Friendly Methods.

Green extraction methods using a combination of mechanical, enzymatic, and green chemical treatments were evaluated for the sequential extraction of carotenoid pigments, protein, and chitin from crab processing discards. Key objectives included avoiding the use of hazardous chemical solvents, conducting as close to a 100% green extraction as possible, and developing simple processes to facilitate implementation into processing plants without the need for complicated and expensive equipment. Three crab bio-products were obtained: pigmented vegetable oil, pigmented protein powder, and chitin.

Enhancing the care navigation model: potential roles for health sciences librarians.

This study analyzed the overlap between roles and activities that health care navigators perform and competencies identified by the Medical Library Association’s (MLA’s) educational policy statement.Roles and activities that health care navigators perform were gleaned from published literature. Once common roles and activities that health care navigators perform were identified, MLA competencies were mapped against those roles and activities to identify areas of overlap.
