I-meso-Erythritol (CAS: 149-32-6) iyingxenye yemvelo yokudla okuningana neziphuzo emazingeni ngezinye izikhathi angaphezu kwe-1 g/kg.Ngokuya ngokugxila okusetshenzisiwe, i-erythritol icishe ibe ngu-60% imnandi njenge-sucrose.Ayinancariogenic futhi ayigayelwanga emzimbeni womuntu okusho ukuthi ayinawo amakhalori.E-European Union, i-erythritol ivunyelwe njenge-E 968 ngenani elikhulu lezicelo zokudla.Kuyi-GRAS e-United States futhi kuvunywe nakwamanye amazwe amaningi.
I-meso-Erythritol iwutshwala obushukela (i-polyol).Ubumnandi be-erythritol buphansi, ubumnandi be-erythritol bungama-60% -70% kuphela we-sucrose, umnyango unokunambitheka okupholile, ukunambitheka kuhlanzekile, futhi akukho post-okumunyu.Ingasetshenziswa ngokuhambisana nezinambitheka ezinomfutho ophezulu ukuvimbela ukunambitheka kwayo okungafuneki kwama-sweetener aphezulu.I-Erythritol inokusimama okuphezulu, izinzile kakhulu ku-asidi nasekushiseni, futhi inokumelana ne-asidi ephezulu kanye ne-alkali.Ngeke ibole futhi ishintshe emazingeni okushisa angaphansi kuka-200℃, futhi ngeke ibhekane nokusabela kwe-Maillard ukuze ibangele ukushintsha kombala.Ukushisa kokuncibilika kwe-erythritol kuphezulu: i-erythritol inomphumela we-endothermic lapho incibilika emanzini, futhi ukushisa kokuncibilika kungu-97.4kJ/kg kuphela, okuphakeme kune-endothermic degree of glucose ne-sorbitol, futhi inomuzwa wokupholisa lapho udla. .I-solubility ye-erythritol ku-25℃ ingu-37% (W/W).Ngokukhuphuka kwezinga lokushisa, ukunyibilika kwe-erythritol kuyanda, futhi kulula ukucwebezela nokuhlukanisa amakristalu.I-Erythritol kulula kakhulu ukuyicwebezela, kodwa ngeke imunce umswakama endaweni enomswakama ongu-90%.Kulula ukuchotshozwa ukuze uthole umkhiqizo oyimpuphu, ongasetshenziswa ebusweni bokudla ukuvimbela ukudla ekubambeni umswakama kanye nokuwohloka.
I-meso-Erythritol, eyingxenye yekilasi likashukela, ikhonjwa emikhiqizweni ehlukahlukene yokudla, izithelo, imifino, iziphuzo kanye nezithako zokudla.Kuyaziwa njengesengezo sokudla esinenkomba ephansi ye-glycemic futhi idlala indima ebalulekile njengesishukela ezigulini ezinesifo sikashukela, ngoba ayinawo umphumela we-glycemic noma we-insulinemic ngenxa yekhono layo lokungatholi i-metabolized kodwa ingene emathunjini amancane.Kubikwa futhi ukuthi isetshenziswa esikhundleni sikashukela endaweni yokuxubha amazinyo, izinsini, imikhiqizo yokudla ye-confectionery, njll.
Inkambu yohlelo lokusebenza
1. Iziphuzo Eminyakeni yamuva nje, i-erythritol isetshenziswe ekuthuthukisweni kwe-zero-calorie entsha neziphuzo ezinekhalori ephansi.I-Erythritol ingakhuphula ubumnandi, umzimba kanye nokushelela kweziphuzo, kuyilapho inciphisa ukubaba, futhi ingavala nezinye iphunga futhi ithuthukise ukunambitheka kweziphuzo.I-Erythritol ingasetshenziswa futhi eziphuzweni eziqinile eziqabulayo, ngoba i-erythritol idonsa ukushisa okuningi lapho incibilika.
2. Izimpahla ezibhakiwe
I-Erythritol iyisithako esifakazelwe sekhwalithi ephezulu yokusebenza noma imikhiqizo yokubhaka enekhalori ephansi.Ayikwazi ukufaka esikhundleni se-sucrose kuphela ngokomzimba nangamakhemikhali kodwa futhi ilethe izinzuzo zezempilo, futhi imikhiqizo ebhakiwe esebenzisa i-erythritol inokubumbana okungcono kwesakhiwo nokuthambile kunemikhiqizo esebenzisa i-sucrose njengezinto zokusetshenziswa, Futhi inombala oncibilikayo emlonyeni nocashile. umehluko.I-erythritol esetshenziswa ezimpahleni ezibhakiwe kufanele kube yimpuphu noma icwebezeliswe ngosayizi wezinhlayiyana ezincane (<200μm), futhi izinhlayiya ezinhle zizoletha ukunambitheka okubushelelezi nokuyindilinga emkhiqizweni.
3. Izithasiselo
I-Erythritol ingase isetshenziselwe ukukhiqiza izithasiselo ezinhle zomkhiqizo webhikawozi ezifana nojamu, ukhilimu, uqweqwe lwebhotela kanye neminye imihlobiso engaphezulu.
A. Ukwengeza i-erythritol kujamu kungathuthukisa inkomba yezithelo zemvelo.
B. Ukwengeza i-erythritol ku-cream icing (amafutha agcwele) ngeke nje kunciphise amakholori kodwa futhi kuletha ukunambitheka okuqabulayo;lapho umkhiqizo usebenzisa i-erythritol, i-maltitol liquid ne-aspartame ngesikhathi esifanayo, inani lamandla lingancishiswa cishe ngama-50%.
4. Amaswidi
Imakethe yamanje yamaswidi kanye nekashokoledi iye yanda kusukela ekusetshenzisweni kokuqala kwe-sucrose njengesisekelo sempahla eluhlaza kuya emikhiqizweni esekelwe kushukela ephansi enekhalori ephansi.Eminyakeni yamuva, imikhiqizo kashukela esebenzayo iye yaphakanyiswa ngokugcwele emakethe futhi isiphenduke indawo yamanje yamazwe ngamazwe I-hotspot yokusetshenziswa nokugxila ekuthuthukisweni kwemakethe yamaswidi, amandla emakethe makhulu.Ngemuva kocwaningo olusebenzayo lwesikhathi eside, kufakazelwe ukuthi i-erythritol entsha esebenzayo ihlangabezana ngokugcwele nezidingo.Ukunambitheka kwe-erythritol kuyafana nokwe-sucrose, futhi asikho isidingo sokwengeza ama-sweeteners aqinile njenge-aspartame noma i-saccharin.Amaswidi avelayo ayabanda futhi ayabanda kunamanye amaswidi "angewona ama-sucrose", anobumnandi obumsulwa futhi abukho ubumnandi obungemuva.
5. Ushokoledi
I-Erythritol ingangena kalula esikhundleni se-sucrose emkhiqizweni futhi inciphise amandla kashokoledi ngama-34%.Ayikho enye utshwala obushukela obungahlinzeka ngokunciphisa amandla anjalo, futhi inikeze umkhiqizo ukunambitheka okupholile kanye nezakhiwo ezingezona ze-cariogenic.Ngenxa ye-hygroscopicity yayo ephansi, i-erythritol isiza ukunqoba isenzakalo sokuqhakaza kwabanye ushukela lapho wenza ushokoledi.
6. Imboni yezemithi
Izakhiwo ze-erythritol, ezifana ne-anti-caries, i-anti-oxidation, ukugcinwa komswakama kanye nokungashisi, zenza ukusetshenziswa kwayo emikhakheni yezokwelapha kanye namakhemikhali nsuku zonke kuqhubeke kwanda.
I-meso-Erythritol iyisakhi esivele ngokwemvelo esingezona i-cariogenic esisetshenziswa ezinhlobonhlobo zamalungiselelo emithi, okuhlanganisa kumafomu omthamo oqinile njengesigcwalisi sethebhulethi, kanye nasezimbotsheni.Iphinde yaphenywa ukuze isetshenziswe kuma-inhalers empushana eyomile.Ibuye isetshenziswe kuma-lozenji angenashukela, kanye neshungamu enemithi.I-meso-Erythritol ingasetshenziswa futhi njengento ehlanjululwe ku-granulation emanzi ihlanganiswe nezidakamizwa ezizwela umswakama.Ezitshalweni ze-buccal, ezifana nezinsini zokuhlafuna ezinemithi, isetshenziswa ngenxa yokushisa kwayo okuphezulu okungalungile kwesisombululo esihlinzeka ngomphumela onamandla wokupholisa.I-meso-Erythritol nayo isetshenziswa njengesiphuzo esingenalokali kumasiraphu;isetshenziselwa ukuhlinzeka ngezakhiwo zokuguqula iphrofayili ngezinzwa ezinamandla;futhi isetshenziselwa ukufihla izinambitheka ezingafunwa.I-meso-Erythritol iphinde isetshenziswe njengesithako esingenashukela esikhumbeni sokuxubha amazinyo nasezixazululweni zokugeza umlomo.
INCAZELO
I-Erythritol itholakala ngokuvutshelwa kwe-enzyme yesitashi i-hydrolyzate (kusuka kusitashi esinjengokolweni nommbila).Itholakala kumhluzi wokuvubela weyeast efanelekile ye-osmophilic efana ne-Moniliella pollinis noma i-Trichosporonoides megachiliensis.Iqukethe i-NLT 96.0% kanye ne-NMT 102.0% ye-Erythritol (C4H10O4), abalwe ngesisekelo se-anhydrous.
