        "summary": "Students at Gorontalo State University have developed a spray hand sanitiser using chitosan extracted from cuttlefish bones, an underused fisheries by-product. Laboratory tests found that antibacterial activity against E. coli increased with higher chitosan concentrations, although further research and safety testing are needed before wider use.",
        "content": "<p>Gorontalo (ANTARA) \u2013 Students at Gorontalo State University (UNG)\nhave innovated by using cuttlefish bones (Sepia sp.) as a raw material\nfor hand hygiene products.<\/p>\n<p>\u201cWe use cuttlefish bones, which are processed into chitosan, a\ncompound attracting interest in the development of various products,\nincluding hygiene products,\u201d said Febriyanti Rasyid, a student at UNG\u2019s\nFaculty of Maritime Affairs and Fisheries Technology, in Gorontalo on\nTuesday.<\/p>\n<p>Febriyanti, Asri Silvana Naiu and Lukman Mile have turned this\nfisheries by-product, which has not been optimally used, into a\nvalue-added raw material.<\/p>\n<p>Chitosan from cuttlefish bones is used as an active ingredient in a\nhand sanitiser spray, and its ability to inhibit Escherichia coli (E.\ncoli) bacteria was tested.<\/p>\n<p>The bacteria are among the microorganisms that can cause health\nproblems if pathogenic strains enter the body through an appropriate\nroute.<\/p>\n<p>The chitosan was formulated at three concentrations: 5 per cent (P1),\n10 per cent (P2) and 15 per cent (P3). The three formulas were tested\nfor pH, viscosity and antibacterial activity against E. coli. The\nresults showed that antibacterial activity increased as the chitosan\nconcentration rose.<\/p>\n<p>The team hopes the research will inspire broader ideas about making\nuse of fisheries resources.<\/p>\n<p>According to Febriyanti, using chitosan from non-crustacean sources\nsuch as cuttlefish also expands the range of natural materials that can\nbe studied for different applications.<\/p>\n<p>She said the research indicates that cuttlefish bones could be a\nsource of chitosan for hand sanitiser spray formulations with\nantibacterial activity against E. coli in laboratory testing.<\/p>\n<p>\u201cBeyond developing a hygiene product formulation, this research shows\nhow fisheries by-products can provide a starting point for scientific\ninnovation,\u201d she said.<\/p>\n<p>\u201cWith further research and adequate safety testing, chitosan from\ncuttlefish bones could be developed further as a value-added ingredient\nin industries based on fisheries resources,\u201d Febriyanti said.<\/p>",
