Waa maxay β-cyclodextrin?
β-cyclodextrin, oo sidoo kale loo yaqaan cyclomalt heptose, heptadextrin cyclic, ama β-CD oo gaaban, waa giraan laga sameeyay istaarij ay soo saareen enzymes microbial oo ka kooban todobo gulukoos oo ku xiran β-1,4-glycosidic bonds, oo leh qaraabo miisaanka molecular ee 1135.
Waxay samayn kartaa dhismooyin isku dhafan oo leh noocyo kala duwan oo xeryahooda ah, taas oo ka dhigaysa mid xasilloon, milmaynaysa, si tartiib tartiib ah u sii deynaysa, emulsifying, antioxidant, anti-decomposition, ilaalinta kulaylka, qoyaan-caddaynta, waxayna leedahay ur maaskaro iyo hawlo kale, sida nooc cusub oo molecular ah. alaabta duubista.

Waa maxay ilaha beta cyclodextrin?
Istaarijka baradhada ceeriin iyo istaarijka sago ayaa la helay inay yihiin istaarjka ceeriin ee ugu habboon ensaymeskan. Sidaa darteed, CGTase la nadiifiyey ayaa awood u leh in loo isticmaalo soosaarka enzymatic ee β-cyclodextrins.
Isticmaalka beta cyclodextrin:
β-cyclodextrin waa wax-soo-saar wanaagsan, wakiilka dhadhanka, xasiliyaha, emulsifier, ilaalinta iyo hagaajinta tayada wax soo saarka warshadaha. Waxaa si weyn loo isticmaalaa in beeraha warshadaha dawooyinka, warshadaha cuntada iyo warshadaha kiimikada maalin kasta si loo hagaajiyo xasilloonida iyo tayada alaabta.

Tilmaamaha β-Cyclodextrin:
β-Cyclodextrin waa heptamer wareeg ah oo ka kooban todoba unug gulukoos oo ay ku biireen "madaxa-ilaa-dabada" ee alfa-1.4. Waxaa soo saaray ficilka enzyme, cyclodextrin glycosyl transferase (CGT), oo ku saabsan sharoobada istaarijka ee hydrolyzed. Oo waa budo cad oo waxaa jira dalool unuggiisa kaas oo samayn kara xeryahooda ka mid noqoshada oo leh noocyo kala duwan oo unugyo ah. Darajada milanka ee Beta-cyclodextrin ee biyaha waa 1.85 g/100ml @ 25°C, barta dhalaalku waa qiyaastii 260℃, dhexroorka guduhu waa 0.7-0.8nm.
