He aha ka β-cyclodextrin?
ʻO ka β-cyclodextrin, ka mea i ʻike ʻia he cyclomalt heptose, cyclic heptadextrin, a i ʻole β-CD no ka pōkole, he apo ia i hana ʻia mai ka starch i unuhi ʻia e nā enzyme microbial a i haku ʻia me nā koena glucose ʻehiku i hoʻopaʻa ʻia e nā paʻa β-1,4-glycosidic, me kahi pili. 1135 ka nui molekiko.
Hiki iā ia ke hana i nā encapsulation complexes me nā ʻano mea like ʻole, e hoʻokūpaʻa, hoʻoheheʻe, hoʻokuʻu lohi, emulsifying, antioxidant, anti-decomposition, mālama wela, moisture-proof, a loaʻa iā ia ka ʻala Masking a me nā hana ʻē aʻe, ma ke ʻano he ʻano molekala hou. mea ʻōwili.
ʻO ka wehewehe ʻana o nā huahana o Beta-cyclodextrin:
- Inoa Huahana:β-Cyclodextrin
- Nā inoa ʻē aʻe: Cycloheptaamylose; Cyclomaltoheptaose; Betadex
- Noi: He mea pono ka β-Cyclodextrin no ka hana ʻana i nā paʻakikī hiki ke hoʻoheheʻe ʻia i ka wai no ka hōʻailona fluorescent o nā protein.
- Helu CAS:7585-39-9
- Maʻemaʻe: ≥98%
- Kaumaha Molekala:1134.98
- Hui Molekala:C42H70O35
He aha nā kumu o ka beta cyclodextrin?
Ua ʻike ʻia ka mākiko ʻuala maka a me ka mākiko sago ʻo ia nā mākoki maka kūpono loa no kēia enzyme. No laila, hiki i ka CGTase hoʻomaʻemaʻe ke hoʻohana i ka hana enzymatic o β-cyclodextrins.
No ka hoʻohana ʻana i ka beta cyclodextrin:
ʻO ka β-cyclodextrin kahi mea hoʻohui maikaʻi, mea ʻono, stabilizer, emulsifier, preservative a me ka hoʻomaikaʻi maikaʻi i ka hana ʻoihana. Hoʻohana nui ʻia ia i ka ʻoihana lāʻau lapaʻau, ʻoihana meaʻai a me ka ʻoihana kemika i kēlā me kēia lā e hoʻomaikaʻi i ka paʻa a me ka maikaʻi o nā huahana.
- Hoʻohana i ka ʻoihana lāʻau lapaʻau
* Hoʻonui i ka paʻa o nā lāʻau lapaʻau
* Hoʻemi i ka huhū, ka ʻawaʻawa, nā hopena ʻaoʻao o ka lāʻau lapaʻau a me ka uhi ʻana i ke ʻala makemake ʻole
* Hoʻonui i ka solubility o nā lāʻau lapaʻau
- Hoʻohana i ka ʻoihana kemika i kēlā me kēia lā
* Hoʻemi i nā hopena ʻaoʻao, hoʻomaikaʻi i ke kūpaʻa, a hoʻonui i ka ʻala
- Hoʻohana i ka ʻoihana meaʻai
* Nā mea hoʻopaʻa, nā mea hoʻokuʻu lohi no nā mea ʻala, nā ʻono, nā ʻono, a me nā puaʻa
* Hōʻoiaʻiʻo i ka wai, hoʻomaʻemaʻe, anti-corrosion, deodorization, emulsification, hoʻonui i ke ola papa
Nā hiʻohiʻona o ka β-Cyclodextrin:
ʻO ka β-Cyclodextrin he heptamer cyclic i haku ʻia me ʻehiku ʻāpana glucose i hui pū ʻia me "head-to-tail" e nā loulou alpha-1.4. Hana ʻia ia e ka hana o ka enzyme, cyclodextrin glycosyl transferase (CGT), ma ka hydrolyzed starch syrups. A he pauda keʻokeʻo a aia kahi lua i loko o kāna mole e hiki ke hana i nā pūhui hoʻohui me nā ʻano mole. ʻO ka degere solubility o Beta-cyclodextrin i loko o ka wai he 1.85 g / 100ml @ 25 ° C, kahi heheʻe ma kahi o 260 ℃, ʻo ke anawaena o loko he 0.7-0.8nm.
No nā huahana hou aku, E ʻoluʻolu e kelepona iā Summer---WhatsApp: +86 13892905035/ Email:sales05@imaherb.com
Puke a me ka waiho ʻana:
E hoʻokomo i loko o nā pahu pepa a me ʻelua ʻeke plastik i loko.
Kaumaha Net: 25kgs/pepa-pahu.
1kg-5kgs ʻeke plastik i loko me ka ʻeke alumini alumini ma waho.
Kaumaha Net: 20kgs-25kgs/pepa-pahu
E kūʻai i loko o kahi pahu i paʻa maikaʻi ʻia mai ke kukui a me ka mālamalama.
