  • Cleveland research team’s squid-like material could lead to better prosthetics and implants

    A Cleveland research team including Paul Marasco, director of amputee research at the Louis Stokes Cleveland VA Medical Center, and led by Case Western Reserve University macromolecular science and engineering professor Stuart Rowan, part of a team pursuing improved prosthetic limbs. has produced a material that mimics the squid beak’s soft-to-hard transition. The scientists created the so-far nameless squid stuff using a scaffold of tiny […]

  • Science devises ways to recycle crustacean shells

    It was only a matter of time before scientists found a way to recycle the 750 000 tonnes of crustacean shells which are disposed of in the EU every year. Asia has successfully managed to extract polymer chitosan (used to make filters, foils and wound dressings) produced from shrimp shells. But in Europe crustaceans contain more lime, so processing is […]

  • Primex Launches Microencapsulated LipoSan Ultra

    Primex has introducted a microencapsulated version of its LipoSan Ultra that is designed for weight loss beverages. The new and unique weight loss ingredient is an innovative development and line extension of Primex’s ordinary weight loss ingredient LipoSan Ultra, a patented product based on ChitoClear chitosan and succinic acid, which has an extraordinary ability to bind to dietary fat so […]

  • ChiBio project looks to develop biorefinery to turn chitin biowaste into monomers

    In many Asian countries, shrimp waste is converted to chitosan, a commercially valuable compound with a myriad of applications ranging from use as a biopesticide to biomedical solutions in tissue engineering, non-viral gene delivery and enzyme immobilisation. The problem is that European crustacean shells harbour higher levels of calcium carbonate, thus making the Asian approach unviable. Now, an EU funded […]

  • Shrimp waste in Venezuela useful to produce artificial skin

    A plant that will process shrimp waste to obtain chitosan has been opened recently in Zulia state. This polymer may be used to make artificial skin to treat patients having burns and diabetes, among many other medical, agricultural and environmental applications. The Ministry of Planning and Finance invested VEB 6,000 million (USD 1.4 million) for opening the plant Innovaquita Environmental […]

  • Company to convert seafood waste into products

    A company that plans to convert seafood waste into a range of commercial products will move into an empty bottling plant in Opelousas, creating 50 new jobs over five years. AgraTech International said Wednesday it will spend $10 million to renovate the old Yoo-Hoo plant. The company will process shrimp, crawfish and crab shells to get chitosan, which is used […]

  • Characterization of allergenic and antimicrobial properties of Chitin and Chitosan and formulation of Chitosan-based edible film for instant food casing

    Derived from shrimp shells, chitin and chitosan are non-toxic, biodegradable and biocompatible. However, some residual proteins from shrimp shells such as tropomyosin and arginine kinase could remain in these products and cause allergic reactions among consumers. Therefore, this study was aimed at investigation of their antimicrobial activity and allergenicity before applying to edible packaging for instant noodles. Two antibodies were […]

  • Beating shoe smells with crab shells

    Portuguese researchers are working to make anti-microbial shoes by treating leather with a modified chemical from crab shells. Chitosan is a linear polysaccharide made from the deacylation of chitin, the structural component that makes up the shells of various crustaceans. In fact, chitin is the second most common dietary fibre after cellulose; however, it’s chitosan’s anti-microbial properties that are being exploited […]

  • Uranium from seawater idea boosted with shrimp shells

    Oceans hold billions of tonnes of uranium at tiny concentrations, but extracting it remains uneconomical. A report at the 244th meeting of the American Chemical Society described a new technique using uranium-absorbing mats made from discarded shrimp shells. Uranium is currently mined from ore deposits around the world, but there are fears that demand may outstrip the supply of ore as […]

  • Chitosan used to lengthen shelf life of bananas in China

    Scientists have figured out how to use chitosan — a substance derived from shrimp and crab shells — to delay the ripening of bananas for up to two weeks. Scientists speaking in Philadelphia at the 244th National Meeting & Exposition of the American Chemical Society described experiments designed to develop a spray-on coating that consumers could use themselves. The coating, […]
