I-Hielscher Ultrasound Technology

I-Solvent-Free Free Extraction nge-Ultrasound

  • Ukukhipha okuvamile kwamatshana amnandi njengama-stevioglycosides avela ku-Stevia rebaudiana usebenzisa ama-solvents anobuthi.
  • Ukuze uthole umkhiqizo wokudla onempilo, onenzuzo, indlela yokukhipha ingenalutho iyadingeka.
  • I-ultrasonic extraction mbambiso igwema ukusetshenziswa kwe-solvents ekufezeni izivuno eziphakeme kakhulu.

Ama-extracts ephilile nge-Ultrasonic Extraction

Ama-sweetener Stevia kufanele abe umkhiqizo ozuzisa impilo owenziwa ngamaqabunga omuthi we-Stevia rebaudiana Bertoni futhi asetshenziswa njenge-sweetener ye-khalori. Ubumnandi bubangelwa yi-diterpenic glycosides ese-approx. Izikhathi ezingu-300 ezimnandi kune-sucrose.
Umthamo we-glycoside we-stevia rebaudiana Bertoni ubhalwe kusuka ku-stevioside (ama-5-10%), i-rebaudioside A (2-4%), i-rebaudioside C (1-2%), i-dulcoside A (0.5-1%), i-rebaudioside B, i-rebadiodiodia D , kanye ne-rebadiodioside E. Ngokungafani namanye ama-glycosides, i-rebaudiana A ibonakala ngokungahambisani nolaka. Ngakho-ke, i-rebaudiana A iyinhlanganisela ehloswe kakhulu kusuka emaqabunga e-stevia. Isizinda se-ultrasonic sisiza ukukhishwa kwe-steviosides kanye nokubuyiselwa kabusha kwe-high-purity. Isizinda se-Ultrasonic I-steviol glycosides ingenziwa kalula emanzini futhi inikeze isivuno esiphezulu izinga lokukhuphula kakhulu. Okulinganayo izinga lokushisa elincane ephakathi kuka-60 ° C no-80 ° C iyamnene ukuze kukhishwe ukuchithwa kwezingqikithi.

Ukukhishwa kwe-Ultrasonic kwe-stevioglycosides kusuka kumaqabunga e-stevia kwenziwa ngokusebenzisa i-Hielscher UP100H. I-Sonication iphazamisa amaseli futhi ikhiphe izinto ezi-bioactive.

Isizinda se-Ultrasonic seStevia sisebenzisa i-UP100H

Kusukela ngaleso sikhathi i-stevia ivunyiwe njenge-sweetener, isidingo soshukela wemvelo, indawo engena esikhundleni se-calorie-free yanda kakhulu. Ukuze unikeze imikhiqizo ye-stevia edingekayo, amandla okukhiqiza kwezohwebo kufanele athulwe. I-Ultrasound iyindlela efakazelwe ukukhuliswa kwesisindo.

Izinzuzo ze-Ultrasonic Extraction:

  • i-solvent-free, isib. emanzini
  • Izithelo Eziphakeme
  • izinga eliphezulu lokukhishwa
  • ukugcina isikhathi
  • izindleko zokulondoloza
  • ephephile
  • ukuphathwa kwemvelo
  • inkinobho noma ukucubungula kwe-inline

Ultrasonic Stevia Extraction: Imiphumela Yokucwaninga

Liu et al. (2010) uphenye isizinda se-ultrasonic se-carbohydrate esiphelele esivela ku-Stevia rebaudiana Bertoni esebenzisa idivayisi yama-ultrasonic kaHielscher UP400S. Ukuze ukwandise isivuno sama-carbohydrate esiphelele kusuka ku-Stevia rebaudiana Bertoni, i-stevia kusuka kohlobo LUYU-131 isetshenziswe njengamasampuli. Indlela yokuphendula impendulo (RSM) yayisetshenziselwa ukwandisa isimo se-ultrasound esisusiwe. Imiphumela yabonisa ukuthi izimo zokukhipha kahle kwakuyizinga lokushisa lokushisa lika-68 ° C, amandla angama-60 W kanye nesikhathi sokukhipha ngamaminithi angu-32. Ukusebenzisa isizinda esisizwa nge-ultrasound, i ukukhiqizwa kokukhipha kwanda nge-factor of 1.5 at izinga lokushisa eliphansi (68 ° C) kanye nesikhathi sokukhipha (amaminithi angu-32) kufushane kufushane uma kuqhathaniswa neyesizinda sangasese. Ukuhlaziywa kwezingxenye zezingqikithi ezingcolile kubonisa ukuthi inani elilinganiselwe le-rebaudioside A lenyuke emaceleni asetshenziselwa i-ultrasound uma kuqhathaniswa nezingqikithi ezitholakale ngenqubo yeklasi, kanti izinhlamvu ezisizwa nge-ultrasound ikhwalithi engcono.

I-Ultrasonic Post-Processing of Steviosides

I-Ultrasound iyindlela enokwethenjelwa yokuxuba, ukuxuba futhi I-homogenizing, ngakho-ke i-ultrasonic ivame ukusetshenziselwa ngesikhathi yokwenza nokuhlanganiswa komkhiqizo wokugcina. Lapho ukukhishwa kwe-stevia kudingeke kuchitheke ku-liquid, i-ultrasound yindlela yokushesha nokuphumelelayo yokulungiselela ukuxuba okuhambisanayo – kungakhathaliseki ukuthi i-viscosity. I-Ultrasonic ukuqedwa ivumela ukulungiselela izixazululo ezigcwele kakhulu nezigcwele ngokweqile.

Ultrasonic Obumba Systems

Uhlobo lomkhiqizo we-Hielscher luyakuthola – kungakhathaliseki ukuthi ufuna ukususa amanani amancane naphakathi kwamasayizi ukuhlaziywa nocwaningo noma ukukhishwa esikalini esikhulu sokukhiqiza kwezohwebo. Ibanga lethu lomkhiqizo we-ultrasonicators lihlanganisa Ultrasonic Lab Amadivayisi, izinhlelo zebhentshi R&D nezitshalo zomshayeli kanye ezimbonini high-power ultrasonic izinhlelo zokusebenza kuze kube Ama-watts angu-16,000 iyunithi ngayinye, engasetshenziswa kalula futhi iqukethe. Ukukhetha kwethu okubanzi kwe-ultrasonic Izesekeli ezifana ne-sonotrode, amaseli okugeleza, ama-reactors kanye nezivikeli ezivumela ukulungiswa okuhle kwesistimu ehambelana nezidingo zamakhasimende ethu.

Investment

Wonke amadivaysi e-ultrasonic ase-Hielscher akhiwe 24/7 ukusebenza kusho ukuthi imishini yethu ivumela ukubuyela ngokushesha kwi-Investment (I-RoI). Alupului et al. (2009) atholakala ngesikhathi sokucwaninga ukuthi iqiniso lokulungiswa kwezomnotho kwesicelo se-high intensity ultrasound njengenhlawulo izindleko eziphansi indlela engayinakwa. Ngaphezu kwalokho, Isizinda se-Ultrasonic iyindlela ekholisayo ngenxa yalo ukusetshenziswa okulula futhi kubalulekile ukusebenza kahle.

I-Hielscher Ultrasonics 'SonoStation iyisethi elula yokusebenzisa i-ultrasonic yezinga lokukhiqiza. (Chofoza ukuze wandise!)

SonoStation – uhlelo lwe-ultrasonic olunama-2x 2kW ultrasonicators, i-tank eshukumisayo kanye nepompo – iyisistimu enomsebenzisi-friendly for isizinda.

Amaqiniso Okufanele Ukwazi

I-Steviol Glycosides

I-Steviol glycosides yizinto, eziphethwe ukunambitheka okumnandi kwamaqabunga e-stevia. Lezi glycosides ze-steviol ziyinkimbinkimbi ye-diterpene. Zinezimo zamakhemikhali ze-molecule ye-steviol lapho i-carboxyl-hydrogen athomu yayo ithathelwa khona yi-molecule ye-glucose ukuze i-ester, ne-hydroxyl hydrogen enehlanganisela ye-glucose ne-rhamnose yokwakha i-acetal.
Ama-steviol glycosides atholakala e-S. rebaudiana amaqabunga afaka (ngamaphesenti angaphezu kwesisindo):

  • I-Stevioside (5-10%)
  • I-Rebaudioside A (2-4%)
  • I-Rebaudioside C (1-2%)
  • I-Dulcoside A (0.5-1%)
  • I-Rebaudioside B
  • I-Rebaudioside D
  • I-Rebaudioside E

I-Rebaudioside B, i-rebaudioside D, i-rebaudioside E itholakala kuphela ngamaminithi amancane. Inhlanganisela ye-steviol glycoside etholakalayo kwezohwebo esetshenzisiwe njenge-sweetener engekho caloric ekhishwe esitshalweni ikakhulukazi yenziwa kusukela ku-approx. I-80% ye-stevioside, i-8% ye-rebaudioside A, ne-0.6% yokubukwa kabusha kwe-C.

Izinsiza ze-Ultrasonic

Ultrasonic izicubu homogenizers kuvame ukubizwa ngokuthi probe sonicator / sonificator, lyser sonic, ultrasound disruptor, grinder ultrasonic, Sono-ruptor, sonifier, dismembrator sonic, iseli disrupter, disperser ultrasonic, emulsifier noma dissolver. Amagama ezahlukene umphumela izicelo ahlukahlukene elingase zigcwaliseke sonication.

Le vidiyo ikhombisa i-Hielscher UP200St ultrasonicator ngesikhathi sokukhishwa kwamakhompiyutha we-bioactive ezintweni zezitshalo.
