He aha ka ʻokoʻa ma waena o Guar lāua ʻo Xanthan Gum

ʻO ka gum Guar a me ka gum xanthan he mau ʻano hydrocolloids i hoʻohana pinepine ʻia e like me nā mea hoʻohui meaʻai a me nā mea hoʻomānoanoa. ʻOiai ke kaʻana like nei lākou i kekahi mau ʻano like i kā lākou mau hana, aia kekahi mau ʻokoʻa koʻikoʻi ma waena o nā mea ʻelua:

1. Puna:

• ʻO Guar Gum: Loaʻa ka Guar gum mai nā hua o ka mea kanu guar (Cyamopsis tetragonoloba), he ʻōiwi ia no India a me Pakistan. Hana ʻia nā hua e unuhi i ka gum, a laila hoʻomaʻemaʻe ʻia a hoʻohana ʻia i nā hana like ʻole.
• Xanthan Gum: Hana ʻia ka Xanthan gum ma o ka fermentation e ka bacteria Xanthomonas campestris. Hoʻoulu ka bacteria i nā kalapona, e like me ka glucose a i ʻole sucrose, e hana i ka xanthan gum. Ma hope o ka fermentation, hoʻoheheʻe ʻia ka gum, hoʻomaloʻo ʻia, a wili ʻia i loko o ka pauka maikaʻi.

2. ʻAno Kemika:

• ʻO Guar Gum: ʻO ka Guar gum kahi galactomannan, he polysaccharide i haku ʻia me kahi kaulahao linear o nā ʻāpana mannose me nā lālā galactose i kekahi manawa.
• ʻO Xanthan Gum: ʻO ka Xanthan gum kahi hetero-polysaccharide i haku ʻia me nā ʻāpana hana hou o ka glucose, mannose, a me ka waikawa glucuronic, me nā kaulahao ʻaoʻao o ka acetate a me ka pyruvate.

3. Ka hoʻoheheʻe ʻia:

• ʻO Guar Gum: Hiki ke hoʻoheheʻe ʻia ka Guar gum i ka wai anuanu akā hana i nā hopena viscous loa, ʻoi aku hoʻi i nā ʻano kiʻekiʻe. Hoʻohana pinepine ʻia ia ma ke ʻano he mea hoʻomānoanoa i nā ʻano meaʻai like ʻole a me nā ʻoihana.
• Xanthan Gum: Hiki ke hoʻoheheʻe ʻia ka Xanthan gum i ka wai anuanu a me ka wai wela a hōʻike i ke ʻano pseudoplastic, ʻo ia hoʻi ke emi nei kona viscosity me ke koʻikoʻi shear. Hoʻokumu ia i nā gels paʻa i ke alo o kekahi mau ions, e kūpono ai no nā ʻano hana like ʻole.

4. Ka mānoanoa a me ke ʻano:

• ʻO Guar Gum: Hāʻawi pinepine ka Guar gum i kahi mānoanoa kiʻekiʻe i nā hopena i hoʻohālikelike ʻia me ka xanthan gum. Hoʻohana pinepine ʻia ia e hāʻawi i kahi ʻano palupalu a momona i nā huahana meaʻai e like me nā mea ʻono, nā ʻaʻahu, a me nā mea ʻē aʻe o ka waiū.
• Xanthan Gum: Hāʻawi ʻo Xanthan gum i nā waiwai hoʻokuʻu a me ka hoʻopaʻa ʻana maikaʻi loa, e hana ana i kahi hopena viscous me kahi ʻano elastic. Hoʻohana pinepine ʻia ia i ka hoʻomoʻa ʻana me ka gluten-free, nā ʻaʻahu salakeke, a me nā huahana waiū e hoʻomaikaʻi i ke ʻano a me ka ʻono o ka waha.

5. Paʻa:

• ʻO Guar Gum: He pilikino ka Gum Guar i ka pH a me nā loli o ka mahana, a e emi iho kona mānoanoa ma lalo o nā kūlana acidic a i nā mahana kiʻekiʻe paha.
• Xanthan Gum: Hōʻike ka Xanthan gum i ke kūpaʻa maikaʻi ma luna o nā ʻano waiwai pH a me nā mahana, e kūpono ana no nā noi e koi ana i ke ola papa lōʻihi a me nā kūlana hana.

6. Nā hopena Synergistic:

• ʻO Guar Gum: Hiki i ka Guar gum ke hōʻike i nā hopena synergistic i ka wā e hui pū ʻia me nā hydrocolloids ʻē aʻe e like me ka locust bean gum a i ʻole xanthan gum. Hoʻonui kēia hui ʻana i ka viscosity a me ke kūpaʻa, e ʻae ana i ka kaohi nui ʻana ma luna o ke ʻano a me ka mouthfeel i nā ʻano meaʻai.
• Xanthan Gum: Hoʻohana pinepine ʻia ka Xanthan gum i ka hui pū ʻana me nā hydrocolloids a i ʻole nā ​​​​thickeners e hoʻokō ai i ke ʻano kikoʻī a me nā waiwai rheological i nā huahana meaʻai.

I ka hōʻuluʻulu manaʻo, ʻoiai ʻo ka guar gum a me ka xanthan gum e lawelawe nei ma ke ʻano he mau mea hoʻomānoanoa a me nā mea hoʻopaʻa i nā noi meaʻai a me nā ʻoihana, ʻokoʻa lākou i ko lākou kumu, ke ʻano kemika, ka solubility, ka viscosity, ke kūpaʻa, a me nā waiwai hoʻololi ʻano. He mea nui ka hoʻomaopopo ʻana i kēia mau ʻokoʻa no ke koho ʻana i ka gum kūpono no nā ʻano kikoʻī a me ka hoʻokō ʻana i nā ʻano huahana i makemake ʻia.
