ʻO ka gum Xanthan, i ʻike ʻia hoʻi ʻo Hanseum gum, he ʻano microbial exopolysaccharide i hana ʻia e Xanthomnas campestris ma o ka ʻenekinia fermentation e hoʻohana ana i nā kalapona ma ke ʻano he mea maka nui (e like me ka palaoa kulina). Loaʻa iā ia ka rheology kū hoʻokahi, ka solubility wai maikaʻi, ka wela a me ke kūpaʻa acid-base, a he kūpono maikaʻi me nā ʻano paʻakai like ʻole, ma ke ʻano he mea hoʻomānoanoa, mea hoʻomaha, emulsifier, stabilizer, hiki ke hoʻohana nui ʻia i ka meaʻai, ka petroleum, ka lāʻau lapaʻau a me nā ʻoihana ʻē aʻe ma mua o 20, ʻo ia ka pae hana nui loa o ka honua a me ka polysaccharide microbial i hoʻohana nui ʻia.
Nā Waiwai:He pauka melemele māmā a keʻokeʻo paha ka Xanthan gum, he pilau iki. Hoʻoheheʻe ʻia i ka wai anuanu a me ka wai wela, he hopena kūlike ʻole, kū i ka hau a me ka heheʻe ʻana, ʻaʻole hoʻoheheʻe ʻia i ka ethanol. Hoʻopuehu ʻia me ka wai a hoʻoheheʻe ʻia i loko o kahi colloid viscous hydrophilic paʻa.
Noi：Me kona rheology kūikawā, ka solubility maikaʻi i ka wai, a me ke kūpaʻa kūikawā ma lalo o nā kūlana wela a me nā kūlana acid-base, ua lilo ka xanthan gum i mea pono ʻole i nā ʻano hana like ʻole. Ma ke ʻano he mea hoʻomānoanoa, mea hoʻomaha, emulsifier, a me ka stabilizer, ua loaʻa iā ia kona ala i loko o nā ʻoihana he 20 a ʻoi, me ka meaʻai, ka petroleum, ka lāʻau lapaʻau, a me nā mea ʻē aʻe he nui.
ʻO ka ʻoihana meaʻai kekahi o nā mea nui i loaʻa i nā pono kupaianaha o ka xanthan gum. ʻO kona hiki ke hoʻonui i ke ʻano a me ke kūlike o nā huahana meaʻai ua lilo ia i mea koho kaulana i waena o nā mea hana. Inā paha i loko o nā mea ʻala, nā mea ʻono, a i ʻole nā mea hana bakena, hōʻoia ka xanthan gum i kahi ʻano waha palupalu a hoihoi. ʻO kona kūlike me nā paʻakai like ʻole e hāʻawi hou aku i kona versatility i ka hoʻomākaukau ʻana i ka meaʻai.
I loko o ka ʻoihana ʻaila, he kuleana koʻikoʻi ko ka xanthan gum i ka ʻeli ʻana a me ka haki ʻana i nā wai. ʻO kona mau waiwai rheological kū hoʻokahi e lilo ia i mea hoʻohui kūpono, e hoʻomaikaʻi ana i ka viscosity wai a me ke kūpaʻa. Eia kekahi, hana ia ma ke ʻano he mea hoʻomalu kānana, e hōʻemi ana i ka hoʻokumu ʻia ʻana o nā keke kānana i ka wā o ke kaʻina hana ʻeli. ʻO kona hiki ke hana ma lalo o nā kūlana mahana a me ke kaomi koʻikoʻi ua lilo ia i koho punahele i waena o nā poʻe loea o ka ʻaila.
Loaʻa i ke kahua lapaʻau ka pōmaikaʻi nui mai nā waiwai kūikawā o ka xanthan gum. ʻO kāna ʻano rheological e ʻae ai i ka hoʻokuʻu ʻana i nā lāʻau lapaʻau i kāohi ʻia, e lilo ia i mea hoʻohui kūpono i nā ʻano lāʻau lapaʻau. Eia kekahi, ʻo kona biocompatibility a me ka biodegradability e kūpono ia no nā noi lapaʻau like ʻole e like me nā ʻaʻahu ʻeha a me nā ʻōnaehana lawe lāʻau lapaʻau i kāohi ʻia.
Ma waho aʻe o nā ʻoihana i ʻōlelo ʻia ma luna, loaʻa ke ala o ka xanthan gum i nā ʻoihana ʻē aʻe he nui, me ka ʻoihana kemika o kēlā me kēia lā. Mai ka toothpaste a hiki i nā shampoos, hāʻawi ka xanthan gum i ke ʻano i makemake ʻia a me ke kūpaʻa o kēia mau huahana.
ʻAʻohe mea like ʻole o ke ola kalepa o ka xanthan gum i ka hoʻohālikelike ʻia me nā polysaccharides microbial ʻē aʻe. ʻO kona laulā o nā noi a me nā waiwai kūikawā i hoʻolilo iā ia i mea hoʻohui no nā mea hana he nui ʻole. ʻAʻohe polysaccharide microbial ʻē aʻe e hiki ke hoʻokūkū i kona versatility a me ka pono.

Ka mālama ʻana:Hiki ke hoʻohana nui ʻia ka gum Xanthan i ka unuhi ʻaila, kemika, ka meaʻai, ka lāʻau lapaʻau, ka mahiʻai, nā kala, nā keramika, ka pepa, ka lole, nā mea hoʻonani, ke kūkulu ʻana a me ka hana pahū a me nā ʻoihana ʻē aʻe he 20 a ʻoi aku ma kahi o 100 mau ʻano huahana. I mea e maʻalahi ai ka mālama ʻana a me ka halihali ʻana, hana pinepine ʻia ia i mau huahana maloʻo. Loaʻa i kona hoʻomaloʻo ʻana nā ʻano lapaʻau like ʻole: ka hoʻomaloʻo vacuum, ka hoʻomaloʻo pahu, ka hoʻomaloʻo pīpī, ka hoʻomaloʻo moena wai a me ka hoʻomaloʻo ea. No ka mea he mea wela ia, ʻaʻole hiki iā ia ke kū i ka mālama wela kiʻekiʻe no ka manawa lōʻihi, no laila ʻo ka hoʻohana ʻana i ka hoʻomaloʻo pīpī e hoʻolilo iā ia i mea hoʻoheheʻe ʻole. ʻOiai he kiʻekiʻe ka pono wela o ka hoʻomaloʻo pahu, ʻoi aku ka paʻakikī o ke ʻano mechanical, a he paʻakikī ke hoʻokō no ka hana ʻoihana nui. ʻO ka hoʻomaloʻo moena wai me nā spheres inert, ma muli o ka hoʻonui ʻia o ka hoʻoili wela a me ka nui a me nā hana wili a me ka wāwahi ʻana, he pōkole hoʻi ka manawa paʻa o nā mea, no laila kūpono ia no ka hoʻomaloʻo ʻana i nā mea viscous wela e like me ka gum xanthan.
Nā akahele no ka hoʻohana ʻana:
1. I ka hoʻomākaukau ʻana i ka hopena xanthan gum, inā ʻaʻole lawa ka hoʻopuehu ʻana, e ʻike ʻia nā ʻōpū. Ma waho aʻe o ka hoʻoulu piha ʻana, hiki ke hoʻohui mua ʻia me nā mea maka ʻē aʻe, a laila hoʻohui ʻia i ka wai me ka hoʻoulu ʻana. Inā paʻakikī mau ka hoʻopuehu ʻana, hiki ke hoʻohui ʻia kahi mea hoʻoheheʻe huikau me ka wai, e like me kahi liʻiliʻi o ka ethanol.
2. He polysaccharide anionic ka Xanthan gum, hiki ke hoʻohana pū ʻia me nā mea anionic a i ʻole non-ionic ʻē aʻe, akā ʻaʻole hiki ke kūlike me nā mea cationic. Loaʻa i kāna hopena ka hoʻohālikelike maikaʻi loa a me ke kūpaʻa i ka hapa nui o nā paʻakai. ʻO ka hoʻohui ʻana i nā electrolytes e like me ka sodium chloride a me ka potassium chloride hiki ke hoʻomaikaʻi i kona viscosity a me ke kūpaʻa. Ua hōʻike like ka calcium, magnesium a me nā paʻakai bivalent ʻē aʻe i ko lākou viscosity. Ke kiʻekiʻe ka nui o ka paʻakai ma mua o 0.1%, hiki i ka viscosity kūpono. ʻAʻole hoʻomaikaʻi ka nui o ka paʻakai kiʻekiʻe i ke kūpaʻa o ka hopena xanthan gum, ʻaʻole hoʻi e pili i kona rheology, pH> I ka hola 10 (ʻike pinepine ʻia nā huahana meaʻai), hōʻike nā paʻakai metala bivalent i kahi ʻano e hana i nā gels. Ma lalo o nā kūlana acidic a neutral paha, ʻo kona mau paʻakai metala trivalent e like me ka alumini a i ʻole ka hao e hana i nā gels. ʻO ka nui o ka nui o nā paʻakai metala monovalent e pale aku i ka gelation.
3. Hiki ke hoʻohui ʻia ka gum Xanthan me ka hapa nui o nā mea hoʻomānoanoa kalepa, e like me nā derivatives cellulose, starch, pectin, dextrin, alginate, carrageenan, a pēlā aku. Ke hui pū ʻia me ka galactomannan, loaʻa iā ia kahi hopena synergistic i ka hoʻonui ʻana i ka viscosity.
I ka hopena, he mea kupanaha maoli ka xanthan gum o ka ʻepekema hou. ʻO kona mau hiki kūikawā ma ke ʻano he mea hoʻomānoanoa, mea hoʻomaha, emulsifier, a me ka mea hoʻopaʻa i hoʻololi i ke ʻano o ka hana ʻana o nā ʻoihana like ʻole. Mai ka meaʻai a mākou e ʻai ai a hiki i nā lāʻau lapaʻau a mākou e hilinaʻi nei, ʻaʻole hiki ke hōʻole ʻia ka hopena o ka xanthan gum. ʻO kona kaulana kalepa a me ka hoʻohana ākea e lilo ia i hale mana maoli i ka honua o nā mea hoʻohui. E apo i ka mana kilokilo o ka xanthan gum a wehe i kona hiki i kāu huahana i kēia lā.
