Nisin CAS 1414-45-5
Nisin ndi mankhwala ophera mabakiteriya a polypeptide opangidwa ndi Streptococcus lactis, omwe ali ndi ma amino acid 34. Akalowa m'thupi la munthu, amawola ndi ma enzyme kukhala ma amino acid osiyanasiyana, osasiya zotsalira, osayambitsa kukana mankhwala, komanso osakhudza ma probiotics m'thupi la munthu. Nisin imatha kuletsa bwino kukula ndi kuberekana kwa mabakiteriya ambiri a Gram-positive omwe amachititsa kuti chakudya chiwonongeke, makamaka kukhala ndi mphamvu yoletsa kutentha kwa Bacillus, Clostridium botulinum ndi Listeria. Nisin ndi mankhwala oteteza chakudya achilengedwe ogwira ntchito bwino kwambiri, osapha poizoni, otetezeka komanso opha zotsatira zoyipa, ndipo ali ndi kusungunuka bwino komanso kukhazikika bwino.

Nisin (Innis), yomwe imadziwikanso kuti lactobacillus peptide, ndi chinthu cha polypeptide chomwe chimapangidwa ndi Streptococcus lactis. Pambuyo poidya, imasungunuka mwachangu kukhala ma amino acid pansi pa pH ya thupi la munthu komanso momwe α -chymotrypsin imagwirira ntchito. Sisintha zomera zomwe zili m'matumbo a munthu kapena kuyambitsa mavuto okhudzana ndi kukana monga maantibayotiki ena. Nisin sidzakhala ndi kukana kosiyanasiyana ndi maantibayotiki ena ndipo ndi mankhwala oteteza chakudya achilengedwe ogwira ntchito bwino kwambiri, osapha poizoni, otetezeka komanso abwino kwambiri. Imatha kuletsa ndi kupha maselo omera ndi ma spores a mabakiteriya osiyanasiyana a Gram-positive monga Bacillus stearophilus, Bacillus cereus, Staphylococcus aureus, Listeria ndi Clostridium botulinum. Ikawonjezeredwa ku chakudya, imatha kuchepetsa kutentha kwa chakudya, kufupikitsa nthawi yoyeretsa, ndikuthandiza chakudya kusunga michere yake yoyambirira, kukoma ndi mtundu.
Nisin ndi mankhwala ophera mabakiteriya ochepa omwe amangopha ndikuletsa mabakiteriya a Gram-positive ndipo sagwira ntchito motsutsana ndi yisiti, mabakiteriya a Gram-negative ndi nkhungu. Ku China, zanenedwa kuti zitha kugwiritsidwa ntchito mu nyama ndi mkaka, ndikugwiritsa ntchito kwambiri 0.5g/kg. Kugwiritsa ntchito kwambiri mu zakumwa ndi zitini zamapuloteni a zomera ndi 0.2g/kg.
