I-meso-Erythritol (i-CAS: i-149-32-6) iyinxalenye yendalo yokutya okuninzi kunye neziselo kumanqanaba ngamanye amaxesha angaphezu kwe-1 g / kg.Ngokuxhomekeke kugxininiso olusetyenzisiweyo, i-erythritol imalunga nama-60 % iswiti njengesucrose.Ayinancariogenic kwaye ayifakwanga kwi-metabolized emzimbeni womntu okuthetha ukuba ayinakhalori okanye ingaphantsi.Kwi-European Union, i-erythritol ivunyiwe njenge-E 968 kwinani elikhulu lezicelo zokutya.Yi-GRAS e-United States kwaye ivunyiwe nakwamanye amazwe amaninzi.
i-meso-Erythritol yi-alcohol yeswekile (i-polyol).Ubumnandi be-erythritol buphantsi, ubumnandi be-erythritol bungama-60% -70% kuphela ye-sucrose, umnyango unencasa epholileyo, i-taste is pure, kwaye akukho post-butterness.Ingasetyenziswa ngokudityaniswa ne-high-intensity sweeteners ukuthintela iincasa zayo ezingafunekiyo ze-high-intensity sweeteners.I-Erythritol inozinzo oluphezulu, izinzile kakhulu kwi-asidi kunye nobushushu, kwaye ine-asidi ephezulu kunye nokumelana ne-alkali.Ayizi kubola kwaye itshintshe kumaqondo obushushu angaphantsi kwe-200℃, kwaye ayisayi kusabela kwi-Maillard ukuze ibangele ukujika kombala.Ubushushu bokutshatyalaliswa kwe-erythritol buphezulu: i-erythritol inefuthe lokuphela kwe-endothermic xa inyibilika emanzini, kwaye ukushisa kokutshatyalaliswa kuphela kwe-97.4kJ / kg, ephezulu kune-degree endothermic ye-glucose kunye ne-sorbitol, kwaye inemvakalelo yokupholisa xa isitya. .I-solubility ye-erythritol kwi-25℃ yi-37% (W/W).Ngokunyuka kweqondo lokushisa, i-solubility ye-erythritol iyanda, kwaye kulula ukuyikhanda kunye nokwahlula iikristale.I-Erythritol ilula kakhulu ukuyiqaqambisa, kodwa ayizukufunxa ukufuma kwindawo yokufuma engama-90%.Kulula ukutyunyuzwa ukufumana imveliso ye powdery, engasetyenziselwa phezu kokutya ukukhusela ukutya ekufunxeni umswakama kunye nokuwohloka.
I-meso-Erythritol, yeklasi ye-alcohols yeswekile, ichongiwe kwiimveliso zokutya ezahlukeneyo, iziqhamo, imifuno, iziselo kunye nezongezo zokutya.Kwaziwa njengesongezo sokutya esisezantsi se-glycemic kwaye idlala indima ebalulekileyo njenge-sweetener kwizigulane ezineswekile, kuba ayinayo i-glycemic okanye i-insulinemic effect ngenxa yokukwazi kwayo ukufumana i-metabolized kodwa ifakwe emathunjini amancinci.Kukwaxelwa ukuba isetyenziselwa indawo yeswekile kwindawo yentlama yamazinyo, iintsini zokuhlafuna, iimveliso zokutya zeconfectionery, njl.
Indawo yosetyenziso
1. Iziselo Kwiminyaka yakutshanje, i-erythritol isetyenziswe ekuphuhliseni i-zero-calorie entsha kunye ne-low-calorie drinks.I-Erythritol inokonyusa ubumnandi, umzimba kunye nokutyibilika kweziselo, ngelixa inciphisa ubukrakra, kwaye inokufihla amanye amavumba kwaye yongeze incasa yesiselo.I-Erythritol isenokusetyenziswa kwiziselo eziqinileyo ezihlaziyayo, kuba i-erythritol ifunxa ubushushu obuninzi xa inyibilika.
2. Izinto ezibhakiweyo
I-Erythritol sisithako esiqinisekisiweyo somgangatho ophezulu wokusebenza okanye iimveliso zokubhaka eziphantsi kweekhalori.Ayinakuthatha indawo ye-sucrose kuphela ngokwasemzimbeni nangokwemichiza kodwa ikwazisa izibonelelo zempilo, kwaye iimveliso ezibhakiweyo zisebenzisa i-erythritol zinokubumbana okungcono kunye nokuthamba kuneemveliso ezikwasebenzisa i-sucrose njengemathiriyeli ekrwada, kwaye inyibilika ngokwahlukileyo emlonyeni kunye nombala ofihlakeleyo. iyantlukwano.I-erythritol esetyenziswe kwiimpahla ezibhakiweyo kufuneka ibe yimpuphu okanye i-crystallized kunye nobukhulu be-particle (<200μm), kunye neengqungquthela ezintle ziza kuzisa ukunambitheka okugudileyo kunye nokujikelezayo kwimveliso.
3. Izongezo
I-Erythritol ingasetyenziselwa ukuvelisa ezongezo zemveliso yokubhaka esemgangathweni efana nejam, ikhrimu, i-icing yebhotolo kunye nokuhonjiswa komphezulu.
A. Ukongeza i-erythritol kwijam kunokwandisa isalathisi seziqhamo.
B. Ukongeza i-erythritol kwi-cream icing (i-fat fat) ayiyi kunciphisa kuphela iikhalori kodwa iphinde izise incasa ehlaziyayo;xa imveliso isebenzisa i-erythritol, i-maltitol liquid kunye ne-aspartame ngexesha elifanayo, ixabiso lamandla lingancitshiswa phantse ngama-50%.
4. Iilekese
Imakethi yangoku yeelekese kunye netshokholethi iye yanda ukusuka ekusetyenzisweni kwangoko kwe-sucrose njengesiseko semathiriyeli ekrwada ukuya kwimveliso entsha eneswekile ephantsi kunye neekhalori ezisezantsi.Kwiminyaka yakutshanje, iimveliso zeswekile ezisebenzayo ziye zaxutywa ngokupheleleyo kwiimarike kwaye ziye zangoku ngamazwe ngamazwe I-hotspot yokusetyenziswa kunye nokugxilwa kophuhliso lweemarike ze-candy, amandla emarike makhulu.Emva kophando olusebenzayo lwexesha elide, kuye kwangqinwa ukuba i-erythritol entsha esebenzayo ihlangabezana ngokupheleleyo neemfuno.Ukunambitheka kwe-erythritol kufana ne-sucrose, kwaye akukho mfuneko yokongeza i-sweeteners enamandla njenge-aspartame okanye i-saccharin.Iilekese ezineziphumo zipholile kwaye zipholile kunezinye iilekese "ezingeyo-sucrose", ezinobumnandi obumsulwa kwaye azinancasa engathandekiyo.
5. Itshokholethi
I-Erythritol inokuthatha indawo ye-sucrose ngokulula kwimveliso kwaye inciphise amandla etshokolethi ngama-34%.Ayikho enye i-alcohol yeswekile enokubonelela ngokunciphisa amandla anjalo, kwaye inike imveliso ngencasa epholileyo kunye neempawu ezingenayo i-cariogenic.Ngenxa ye-hygroscopicity ephantsi, i-erythritol inceda ukoyisa isenzeko esidubulayo sezinye iswekile xa sisenza itshokolethi.
6. Ishishini lamachiza
Iimpawu ze-erythritol, ezifana ne-anti-caries, i-anti-oxidation, ukugcinwa komswakama kunye nokungatsha, yenza ukusetyenziswa kwayo kwiinkalo zonyango kunye neekhemikhali zemihla ngemihla ziqhubeka zanda.
I-meso-Erythritol sisincedisi esingenancariogenic esenzeka ngokwendalo esisetyenziswa kumalungiselelo ahlukeneyo oxubo mayeza, kubandakanywa neefomu zedosi eqinileyo njengesizaliso sethebhulethi, kunye nakwiingubo zokwaleka.Ikwaphandiwe ukuba isetyenziswe kwizifunxa ezomileyo zomgubo. Ikwasetyenziswa kwiilozenji ezingenaswekile, kunye netshungama eneyeza.I-meso-Erythritol isenokusetyenziswa njenge-diluent kwigranulation emanzi idityaniswe namachiza angevani nokufuma.Kwizicelo ze-buccal, ezifana neentsini ezixutywe ngamayeza, isetyenziswa ngenxa yobushushu bayo obuphezulu besisombululo esibonelela ngesiphumo esinamandla sokupholisa.i-meso-Erythritol ikwasetyenziswa njenge-sweetener engekho-caloric kwiisyrups;isetyenziselwa ukubonelela ngeempawu zokuguqula iprofayili kunye ne-sweeteners enzulu;kwaye ikwasetyenziselwa ukugquma iincasa ezingafunwayo.I-meso-Erythritol ikwasetyenziswa njenge-noncariogenic sweetener kwintlama yamazinyo kunye nezisombululo zokuhlamba umlomo.
INGCACISO
I-Erythritol ifumaneka ngokubiliswa kwe-starch enzyme hydrolyzate (ukusuka kwistatshi esifana nengqolowa kunye nombona).Ifunyenwe kumhluzi wokubilisa we-osmophilic yeasts efanelekileyo njenge-Moniliella pollinis okanye i-Trichosporonoides megachiliensis.Iqulethe i-NLT 96.0% kunye ne-NMT 102.0% ye-Erythritol (C4H10O4), ibalwe ngokwesiseko se-anhydrous.
