ʻO ka sodium metabisulphite: he mea nui i ka ʻoihana meaʻai

ʻO ka sodium metabisulphite (Na2S2O5) he pauka crystalline kala ʻole i hoʻohana nui ʻia i ka meaʻai, nā mea hoʻonaninani, nā lāʻau lapaʻau a me nā mea textiles, a he mea koʻikoʻi sulphite pūhui.Aia i loko o ʻelua mau ion sulfinyl a me ʻelua ion sodium.Ma lalo o nā kūlana acidic, e hoʻoheheʻe ʻia ka sodium metabisulphite i ka sulfur dioxide, ka wai a me ka sulphite, no laila ua hoʻohana nui ʻia i ka ʻoihana meaʻai a me ka ʻoihana inu, e pāʻani ana i kahi disinfection, sterilization a me ka hana antioxidant.

1. ʻO ke kinona a me nā waiwai o ka sodium metabisulphite

ʻO ka sodium metabisulphite ka waiwai kino a me ke kemika, ʻo kona molecular formula ʻo Na2S2O5, ʻo ka molecular mass he 190.09 g / mol, ʻo ka density he 2.63 g / cm³, ʻo ka helu hoʻoheheʻe he 150 ℃, ʻo ka paila e pili ana i 333 ℃.ʻO ka sodium metabisulphite kahi aniani kala ʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai a me ka glycerol, paʻa i nā hopena alkaline, a hiki ke hoʻoheheʻe ʻia i loko o ka sulfur dioxide a me nā ion sulphite ma lalo o nā kūlana acidic.Paʻa ka sodium metabisulphite i ka ea maloʻo, akā e wāwahi ʻia i ka ea haʻahaʻa a i ʻole i nā wela kiʻekiʻe.

2. Ke kahua noi o ka sodium metabisulphite

ʻO ka sodium metabisulphite kahi mea hoʻohui meaʻai i hoʻohana nui ʻia, hoʻohana ʻia i nā huahana ʻiʻo, nā huahana wai, nā mea inu, nā mea inu malt, soy sauce a me nā meaʻai ʻē aʻe e like me ka antioxidant, preservative a me ka bleach.Hiki ke hoʻohana ʻia no ka hana ʻana i nā meaʻai ʻono e like me nā mea ʻono, nā kini, nā jams a me nā mea mālama e hoʻonui ai i ko lākou ola a me ka ʻono.Hiki ke hoʻohana ʻia ʻo Sodium metabisulphite ma ke ʻano he catalyst i ka ʻoihana wahie, bleaching agent i ka ʻoihana pepa, pharmaceutical additives, a me nā mea hoʻohui kemika i nā kala a me nā kaʻina textile.

3. Mechanism o ka hana o ka sodium metabisulphite

ʻO ka hana nui o ka sodium metabisulphite ma ke ʻano he meaʻai meaʻai he antioxidant a me ka preservative.Hiki iā ia ke pale pono i ka momona o ka momona i ka meaʻai, e hoʻolohi i ka hōʻino ʻana o ka meaʻai, a no laila e hoʻolōʻihi i ke ola o ka meaʻai.I ka manawa like, hiki i ka sodium metabisulphite ke pale aku i ka ulu ʻana o ka bacteria a me ka polū i ka meaʻai a pale aku i ka hoʻohaumia ʻana i ka meaʻai e nā microorganisms.Loaʻa kēia hopena antioxidant a me antibacterial e ka sulfur dioxide a me nā ion sulphite i hana ʻia e ka decomposition o ka sodium metabisulphite.

Ma waho aʻe o kāna noi ʻana i ka ʻoihana hana meaʻai, hiki ke hoʻohana ʻia ka sodium metabisulphite ma ke ʻano he kemika ma nā ʻano ʻē aʻe, e like me nā catalysts wahie, bleach agents, pharmaceutical additives, etc. ʻokoʻa nō hoʻi, akā pili lākou a pau i kā lākou antioxidant, antiseptic, bactericidal and bleaching properties.

4.Safety a me ka hopena o ke kaiapuni o ka sodium metabisulphite

ʻO ka sodium metabisulphite kahi mea hoʻohana nui ʻia, a ʻo kona hopena i ke olakino kanaka a me ka palekana o ke kaiapuni ua huki nui ʻia.Ma keʻano laulā, palekana ka sodium metabisulphite i ka hoʻohana ʻana i loko o ka pae hoʻohālikelike i kuhikuhi ʻia.Eia nō naʻe, inā e hoʻohana nui ʻia a lōʻihi ka hoʻohana ʻana i nā kiʻekiʻe o ka sodium metabisulphite hiki ke loaʻa i kekahi mau hopena i ke olakino kanaka, e like me ka ʻili o ka ʻili, ka pilikia o ka hanu, nā allergies, a me nā mea ʻē aʻe. hiki ke hana i ka SOx (sulfur oxides) a me nā mea haumia ʻē aʻe, e hana ana i kekahi hopena maikaʻi ʻole i ke kaiapuni.No laila, i ka wā e hoʻohana ai i ka sodium metabisulphite, pono e noʻonoʻo ʻia ka mana a me ka palekana e pale aku i nā pōʻino a me nā hopena kūlohelohe.

I ka pōkole, ʻo ka sodium metabisulphite he mea hoʻohana nui ʻia, he mea koʻikoʻi kemika i ka hoʻoili ʻana i ka meaʻai, nā mea hoʻonaninani, nā lāʻau lapaʻau a me nā textiles.He nui nā waiwai hana e like me ka anti-oxidation, anti-corrosion, sterilization, bleaching a pēlā aku, a he mea koʻikoʻi koʻikoʻi i nā kula he nui.Eia nō naʻe, i ke kaʻina o ka hoʻohana ʻana, pono nō e hoʻolohe i nā pilikia o ka palekana a me ka palekana o ke kaiapuni i mea e hāʻawi ai i ka pāʻani piha i kāna mau hopena maikaʻi a pale aku i nā hopena maikaʻi ʻole i ke olakino kanaka a me ke kaiapuni.
