ʻO 1. Xanthan gum kahi mea polysaccharide kaumaha nui i polymerized mai ka hui like me 5 Molecular sugars ma ke ʻano he ʻāpana.Hoʻokumu ʻia kēlā me kēia ʻāpana me 2 mau mole o ka glucose, 2 mau mole o ka mannose a me 1 mole o ka glucuronic acid.ʻO kāna kaulahao nui i haku ʻia me ka β- Ua hoʻopili ʻia ʻo Glucose e ka pilina 1,4-glycosidic.ʻO ke ʻano o 2 mau mole o ka glucose ka like me ka cellulose.Aia 2 mole o ka mannose a me 1 mole o ka glucuronic acid ma ka C3 o ka glucose e hana ai i kaulahao aoao.Aia nā hui ʻaoʻao pyruvic acid a me carboxylic acid ma ke kaulahao ʻaoʻao.Ma muli o ka loaʻa ʻana o nā pūʻulu ʻakika i kāna kaulahao ʻaoʻao, hōʻike ia i nā polyanions i loko o ka wai wai, e hana ana i ʻekolu pae ʻekolu-dimensional ʻano o ka xanthan gum. helix e nā paʻa hydrogen, ʻoiai ua mālama ʻia ke ʻano helical pae ʻelua e nā paʻa nāwaliwali ʻole covalent, e hana ana i ka "super bonded ribbon helical polymer".ʻO kāna hana kūikawā e pili ana i ka pyruvic acid i loko.ʻO ka maʻamau, hiki ke hoʻohana ʻia ka ʻona pyruvic acid i ka xanthan gum e ana i kāna hana.

2.Typical rheological waiwai, kiʻekiʻe viscosity i ka haʻahaʻa hoʻopaʻa haʻahaʻa, wela ke kū'ē, acid resistance, alkali resistance, enzymatic hydrolysis resistance, compatibility, solubility, dispersion, paʻa wai.

3.Solubility hiki ke hoʻoheheʻe i ka wai, hikiʻole ke hoʻoheheʻe i ka ethanol (ot-42).E lawe i 300ml wai no ka ho'āʻo ʻana i ka gel, e hoʻokomo i loko o ka beaker 400ml, e hoʻomaʻamaʻa mua i ka 80 ℃, a hoʻohui i 1.5g o ka laʻana a me 1.5g o ka pauka carrageenan ma lalo o ka hoʻoulu ʻana i ka mīkini ikaika.E hoʻoulu a hiki i ka hoʻokumu ʻana o ka hopena, a laila hoʻomau i ka hoʻoulu ʻana no 3chemicalbook0min.I ka wā o ka hui ʻana, ʻaʻole e emi ka mahana o ka wai ma mua o 60 ℃, e hoʻōki i ka hui ʻana, a hoʻomaha i ka lumi lumi no ka ʻoi aku ma mua o 2H.Ke emi iho ka mahana ma mua o 40 ℃, pono e hana ʻia kahi ʻōpala paʻa e like me ka gel, akā ʻaʻole e hana ʻia kēlā gel inā hoʻohana wale ʻia ka hāpana ma kahi o ka hoʻonā mana 1% i hoʻomākaukau ʻia e ke ʻano like me ka carrageenan.

1. I ka wili ʻana o ka ʻoihana ʻaila, hiki i ka 0.5% xanthan glue solution ke mālama i ka viscosity o ka wai hoʻoheheʻe wai a hoʻomalu i kona mau waiwai rheological, i mea liʻiliʻi loa ka viscosity o ka bit rotating kiʻekiʻe. .Eia nō naʻe, mālama ʻo ia i ka viscosity kiʻekiʻe i ka ʻāpana wili static, kahi mea e hana ai i ka pale ʻana i ka hiolo ʻana o ka pā luawai a hoʻomaʻamaʻa i ka ʻoki ʻana i ka ʻiliʻili mai loko mai o ka pūnāwai.

2. I ka ʻoihana meaʻai, ʻoi aku ka maikaʻi ma mua o nā mea hoʻohui meaʻai e like me ka gelatin, CMC, ka limu a me ka pectin.ʻO ka hoʻohuiʻana i ka 0.2% - 1% i ka wai hua e loaʻa i ka wai hua ka hoʻopili maikaʻi, kaʻono maikaʻi, a me ka mālamaʻana i ke komoʻana a me ke kahe;Ma ke ʻano he mea hoʻohui i ka berena, hiki i ka puke kemika ke hana i ka palaoa paʻa, paʻa, mālama i ka manawa a hoʻemi i ke kumukūʻai;ʻO ka hoʻohana ʻana i ka 0.25% i ka hoʻopiha ʻana i ka berena, ka hoʻopiha ʻana i ka meaʻai a me ka icing hiki ke hoʻonui i ka ʻono a me ka ʻono, hoʻomaʻamaʻa i ka hoʻonohonoho ʻana o nā huahana, hoʻonui i ke ola o ka papa, a hoʻomaikaʻi i ke kūpaʻa o nā huahana i ka wela a me ka hau;I nā huahana waiu, hiki ke hoʻohui i ka 0.1% - 0.25% i ka ice cream i kahi hana stabilizing maikaʻi loa;Hiki iā ia ke hāʻawi i ka mana viscosity maikaʻi i ka meaʻai canned, a hiki ke pani i kahi ʻāpana o ka starch.Hiki i kekahi ʻāpana o ka xanthan gum ke hoʻololi i 3 ~ 5 mau ʻāpana o ka starch.I ka manawa like, ua hoʻohana nui ʻia ka xanthan gum i ka candy, condiments, meaʻai hau a me ka meaʻai wai.
