  • Chitin-derived microneedle patch could replace standard tuberculosis skin test

    Each year, millions of people in the United States get a tuberculosis skin test to see if they have the infection that still affects one third of the world’s population. But the standard diagnostic test is difficult to give, because a hypodermic needle must be inserted at a precise angle and depth in the arm to successfully check for tuberculosis. […]

  • Shrimp shells offer jumbo benefits

    Norwegian food research institute Nofima is participating in a major EU-financed project in which ‘active’ packaging based on raw materials from shrimp shell improves and conserves food products and after use the packaging biodegrades. In the n-CHITOPACK project researchers are looking at biodegradable packaging made of chitin and chitosan from shrimp shells that will improve and conserve food products. Products […]

  • 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 […]

  • Nofima Scientists Develop Biodegradable Food Packaging Made of Chitin & Chitosan from Shrimp Shell

    Scientists at Nofima are participating in a major EU-financed project in which “active” packaging based on raw materials from shrimp shell improves and conserves food products – and after use the packaging biodegrades. Environmentally stubborn plastic is getting competition from biodegradable packaging made of chitin and chitosan from shrimp shell. Nofima’s part of the project equates to around NOK 1 […]

  • 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 […]
