ʻO nā huahana ʻiʻo kekahi o nā kumu nui o ka protein a mākou e ʻai ai. E like me ka ʻōlelo ʻana, puka mai nā maʻi mai ka waha, nui ka nui o nā mea kanu meaʻai meaʻai e nānā nui i ka hoʻomaʻemaʻe a me ka palekana. Eia nō naʻe, ʻoi aku ka nui o nā meaʻai i ka protein a ʻoi aku ka nui o ka loaʻa ʻana o nā maʻi maʻi. ʻO ka sterilization mahu, wehe a hoʻopau paha i nā microorganism pathogenic ma ke ala hoʻouna; ka kiʻekiʻe-mehana sterilization mokuahi mīkini hana hoʻokō i nā koi o ka pollution-noa, a me ka pono pale i ka laha o ka bacteria i loko o ka meaʻai huahana hale hana.
ʻO nā huahana ʻiʻo he waiwai nui i ka protein a me ka momona a he kumu maikaʻi ia o nā meaʻai no ka bacteria. ʻO ka maʻemaʻe i ka wā o ka hana ʻana i nā huahana ʻiʻo he mea pono ia no ka hōʻoia ʻana i ka maikaʻi a me ka palekana o nā huahana ʻiʻo. Nui nā kumu o ka maʻi bacteria i ka hana ʻiʻo. He paʻakikī nā kumu o ka haumia e like me ka wai, ka ea a me nā mea hana hana a pili i kēlā me kēia ʻano o ke kaʻina hana. No laila, ʻo ke koho ʻana i kahi ala disinfection maikaʻi i ka hana ʻana a me ka hana ʻana i nā huahana ʻiʻo he mea nui loa ia no ka poʻe a me ka meaʻai. He mea ko'iko'i ka ho'ohana 'ana i ka mahu mai ka mea hana mahu me ka poino li'ili'i no ka disinfection.
Hoʻohana nui ʻia ke ʻano o ka hoʻomaʻamaʻa ʻana i ka mahu, a hiki ke hoʻomaʻemaʻe ʻia nā mea ʻuʻuku a pau e nā mea hana mahu. Loaʻa i ka mahu kiʻekiʻe ke komo ikaika a me ka hopena sterilization ikaika. Hoʻokomo ka mahu wela wela i loko o ka mea, hoʻopaʻa koke a hoʻopaʻa i ka bacteria a hiki i ka make ʻana, he manawa pōkole. Hoʻololi pololei ka mea hana mahu i ka wai i ka mahu wela kiʻekiʻe, ʻaʻole i loko o nā mea haumia ʻē aʻe a i ʻole nā mea kemika, e hōʻoiaʻiʻo ana i ka palekana a me ka ʻai ʻana o nā huahana ʻiʻo sterilized.
Ua loea ʻo Nobeth i ka noiʻi hoʻoheheʻe mahu no 20 mau makahiki a nona kahi ʻoihana hana paila B Class B, kahi hōʻailona i ka ʻoihana mīkini hoʻokele mahu. He kiʻekiʻe ka pono a me ka liʻiliʻi liʻiliʻi, ʻaʻole pono ʻo Nobeth i kahi palapala boiler. He kūpono no 8 mau ʻoihana nui e like me ka hoʻoponopono ʻana i ka meaʻai, ka hao lole, nā lāʻau lapaʻau lapaʻau, ka ʻenekini biochemical, ka noiʻi hoʻokolohua, nā mīkini paʻi, ka mālama ʻana i ka lepo, a me ka hoʻomaʻemaʻe wela kiʻekiʻe. Ua lawelawe ʻo ia ma mua o 200,000 mau mea kūʻai aku i ka huina, a ua uhi kāna ʻoihana ma mua o 60 mau ʻāina a me nā wahi a puni ka honua.
