wehewehe pōkole:

Ferrous Sulphate Hephydrate: Green vitriol, FeSO4.7H20, ua ʻike ʻia mai ka makahiki ʻumikumamākolu;he crystallize mai nā haʻina o ka hao a i ʻole ke kumu hao i loko o ka waikawa sulfuric dilute.Hoʻokumu ka heptahydrate i nā kristal monoclinic ʻōmaʻomaʻo o ka density 1·88, hiki ke hoʻoheheʻe ʻia i ka wai (296 g lita-1 FeS04 ma 25°C).Ma ka hoʻokahe ʻana i ka wai wai me ka ethanol, e hoʻomehana ana i ka heptahydrate i 140° i loko o ka vacuo a i ʻole ma ka crystallizing mai ka 50% sulfuric acid, loaʻa ka monohydrate keʻokeʻo.Hiki ke hoʻomaʻemaʻe hou ʻia kēia i ka FeSO4 amorphous keʻokeʻo ma o ka hoʻomehana ʻana i 300° i loko o ka wai hydrogen.Ma ka wela wela e hoʻoheheʻe ʻia ka sulphate: 2FeS04 -> Fe203+S02+S03 A tetrahydrate, FeS04.4H20, crystallizes mai nā haʻina wai ma luna o 56°.

1. ʻO nā meaʻai meaʻai (iron enhancer);kala mua o ka hua a me ka mea kanu;no ka laʻana, hiki i ka huahana paʻakai i hoʻohana pū ʻia me ka alum maloʻo i loko o ka eggplant hiki ke hana i ka paʻakai paʻa paʻa me kona puaʻa e pale ai i ka discoloration ma muli o nā waikawa organik.Eia naʻe, pono e hoʻomaopopo ʻia, no ka laʻana, e lilo ia i ʻīnika ʻeleʻele ma luna o ka nui o ka hao.Ke kiʻekiʻe ka nui o ka alum, e paʻa loa ka ʻiʻo o ka ʻiʻo eggplant pickled.ʻO ka laʻana hoʻohālikelike: ʻo ka eggplant lōʻihi 300 kg;paʻakai ʻai 40kg;ferrous sulfate 100g;alum maloʻo 500g.Hiki ke ho'ohana 'ia ma ke 'ano he mea hana kala o ka pi'i 'ele'ele, ka pī i ho'olapalapa 'ia a me ke kelp.ʻAʻole pono e hoʻohana ʻia nā meaʻai i loaʻa nā tannins, i mea e pale aku ai i ka ʻeleʻele.Hiki ke hoʻohana ʻia no ka sterilization, deodorization a me ka bactericidal nāwaliwali loa.
2. Loaʻa i nā legumes ka pigment cryptochromic ʻaʻole waihoʻoluʻu ma ke ʻano hoʻohaʻahaʻa ʻoiai e hoʻoneʻe ʻia ana i ʻeleʻele ma luna o ka oxidation ma ke kūlana alkaline.ʻO ka hoʻohana ʻana i ka waiwai hōʻemi o ka ferrous sulfate hiki ke hoʻokō i ke kumu o ka pale kala me ka nui o ka hoʻohana ʻana o 0.02% a 0.03%.
3. Inā hoʻohanaʻia no ka hanaʻana i ka paʻakai hao, ka hao oxide pigments, mordant, purifying agent, preservatives, disinfectants a me ka lāʻau no nā lāʻau anti-anemia.
ʻO 4.Ferrous sulfate (FeSO4) ka mea i ʻike ʻia he hao sulfate a i ʻole iron vitriol.Hoʻohana ʻia ia i ka hana ʻana i nā kinikona like ʻole, e like me ka sulfur dioxide a me ka sulfuric acid.
5. ʻO Ferrous Sulfate kahi meaʻai a me nā meaʻai meaʻai he kumu hao.he pauda keokeo a hina hina.ʻO ka ferrous sulfate heptahydrate he 20% ka hao, aʻo ka ferrous sulfate maloʻo he 32% ka hao.hoʻoheheʻe mālie ia i ka wai a loaʻa ka bioavailability kiʻekiʻe.hiki iā ia ke hoʻoneʻe a me ka rancidity.hoʻohana ʻia ia no ka hoʻopaʻa ʻana i nā hui bakena.i loko o ke ʻano encapsulated ʻaʻole ia e pane me nā lipids i ka palaoa cereal.hoʻohana ʻia i nā meaʻai pēpē, cereals, a me nā huahana pasta.
