Nisin CAS 1414-45-5
He mea antibacterial polypeptide ʻo Nisin i hana ʻia e Streptococcus lactis, nona nā waikawa amino 34. Ke komo i loko o ke kino o ke kanaka, hoʻoheheʻe ʻia e nā enzymes i loko o nā waikawa amino like ʻole, ʻaʻohe koena e waiho ana, ʻaʻole e hoʻoulu i ke kūʻē ʻana i ka lāʻau, a ʻaʻole hoʻi e hoʻopilikia i nā probiotics i loko o ke kino o ke kanaka. Hiki iā Nisin ke kāohi pono i ka ulu ʻana a me ka hana hou ʻana o nā bacteria Gram-positive he nui e hoʻoulu ai i ka palaho ʻana i ka meaʻai, ʻoiai he hopena pale ikaika i ka Bacillus, Clostridium botulinum a me Listeria kūpaʻa wela. He mea mālama meaʻai kūlohelohe maikaʻi loa ʻo Nisin, ʻaʻohe mea ʻawaʻawa, palekana a me ka hopena ʻaoʻao, a he solubility maikaʻi a kūpaʻa hoʻi.

ʻO Nisin (Innis), i ʻike ʻia hoʻi ʻo lactobacillus peptide, he mea polypeptide i hana ʻia e Streptococcus lactis. Ma hope o ka ʻai ʻana, ua hydrolyzed koke ʻia i loko o nā waikawa amino ma lalo o nā kūlana pH physiological o ke kino kanaka a me ka hana a α-chymotrypsin. ʻAʻole ia e hoʻololi i ka flora maʻamau i loko o ke ala ʻōpū o ke kanaka a i ʻole e hoʻoulu i nā pilikia kū'ē e like me nā antibiotics ʻē aʻe. ʻAʻole e kū'ē ʻo Nisin me nā antibiotics ʻē aʻe a he mea mālama meaʻai kūlohelohe maikaʻi loa, ʻaʻohe ʻawaʻawa, palekana a maikaʻi loa. Hiki iā ia ke kāohi a pepehi i nā cell vegetative a me nā spores o nā bacteria Gram-positive like ʻole e like me Bacillus stearophilus, Bacillus cereus, Staphylococcus aureus, Listeria a me Clostridium botulinum. Ke hoʻohui ʻia i ka meaʻai, hiki iā ia ke hoʻohaʻahaʻa nui i ka mahana sterilization o ka meaʻai, hoʻopōkole i ka manawa sterilization, a kōkua i ka meaʻai e mālama i kāna mau meaʻai mua, ʻono a me ke kala.
He mea antibacterial ʻano haiki ʻo Nisin hiki ke pepehi wale a kāohi i ka bacteria Gram-positive a ʻaʻole pono e kūʻē i nā hū, nā bacteria Gram-negative a me nā ʻōpala. Ma Kina, ua ʻōlelo ʻia hiki ke hoʻohana ʻia i nā huahana ʻiʻo a me nā huahana waiū, me ka hoʻohana nui ʻana he 0.5g/kg. ʻO ka hoʻohana nui ʻana i nā mea inu protein mea kanu a me nā kini he 0.2g/kg.
