meso-Erythritol (CAS: 149-32-6) inzvimbo yechisikigo yezvikafu zvakati wandei uye zvinwiwa mumazinga dzimwe nguva anopfuura 1 g/kg.Zvichienderana nehuwandu hunoshandiswa, erythritol inenge 60% inotapira se sucrose.Iyo isiri-cariogenic uye haina metabolized mumuviri wemunhu zvinoreva kuti yakanyanya kana kushoma calorie-isina.MuEuropean Union, erythritol inotenderwa seE 968 yehuwandu hukuru hwekushandisa chikafu.Iyo GRAS muUnited States uye zvakare yakatenderwa mune dzimwe nyika dzakawanda.
meso-Erythritol idoro reshuga (polyol).Iko kutapira kwe erythritol kwakaderera, kutapira kwe erythritol kunongova 60% -70% ye sucrose, musuo une kuravira kunotonhorera, kuravira kwakachena, uye hapana post-inovava.Inogona kushandiswa pamwe chete nepamusoro-kusimba zvinotapira kuti inhibits yayo Isingadiwi inonaka yepamusoro-kusimba zvinotapira.Erythritol ine kugadzikana kwepamusoro, yakagadzikana zvakanyanya kune asidhi nekupisa, uye ine yakakwira asidhi uye alkali kuramba.Iyo haizoora uye ichichinja pane tembiricha iri pasi pe200 ℃, uye haizoitirwe Maillard kuita kukonzeresa.Kupisa kwekuparara kwe erythritol kwakakwirira: erythritol ine endothermic effect kana yakanyungudutswa mumvura, uye kupisa kwekuparara kunongova 97.4kJ / kg, iyo yakakwirira kudarika endothermic degree yeglucose uye sorbitol, uye ine manzwiro ekutonhora paunenge uchidya. .Kunyungudika kwe erythritol pa25 ℃ i37% (W/W).Nekuwedzera kwekushisa, kunyungudika kwe erythritol kunowedzera, uye zviri nyore kupenya uye kuparadzanisa kunze makristasi.Erythritol iri nyore kupenya, asi haitore hunyoro munzvimbo ine hunyoro hwe90%.Zviri nyore kuputsika kuti uwane chigadzirwa chehupfu, chinogona kushandiswa pamusoro pezvokudya kudzivirira zvokudya kubva pakunwa unyoro uye kuora.
Meso-Erythritol, yekirasi yezvinwiwa zveshuga, inowanikwa mune zvakasiyana-siyana zvekudya, michero, miriwo, zvinwiwa uye zvekudya zvinowedzera.Iyo inozivikanwa seyakaderera glycemic chikafu chekuwedzera uye inoita basa rakakosha sekutapira kuvarwere vane chirwere cheshuga, sezvo isina glycemic kana insulinemic mhedzisiro nekuda kwekugona kwayo kusawana metabolized asi kunyura mudumbu diki.Inonzi zvakare inoshandiswa sechinotsiva shuga mune mushonga wemazino, chewing gums, confectionery chikafu zvigadzirwa, nezvimwe.
Nzvimbo yekushandisa
1. Zvinwiwa Mumakore achangopfuura, erythritol yakashandiswa mukugadzirwa kwezero-calori itsva uye zvinwiwa zvakaderera-calori.Erythritol inogona kuwedzera kutapira, muviri uye kutsetseka kwezvinwiwa, uku ichideredza kuvava, uye inogona zvakare kuvhara kumwe kunhuhwirira uye kuwedzera kunaka kwezvinwiwa.Erythritol inogona zvakare kushandiswa mukuzorodza zvinwiwa zvakasimba, nekuti erythritol inotora kupisa kwakawanda kana yanyungudika.
2. Zvinhu zvakabikwa
Erythritol chinhu chakasimbiswa chemhando yepamusoro inoshanda kana yakaderera-calori yekubheka zvigadzirwa.Haikwanise kungotsiva sucrose mumuviri uye mumakemikari asiwo inounza hutano hwakanaka, uye zvigadzirwa zvakabikwa zvinoshandisa erythritol zvine zvirinani zvimisikidzo uye kupfava pane zvigadzirwa zvinoshandisawo sucrose seyakagadzirwa zvinhu, Uye ine zvakasiyana kunyunguduka-mu-mumuromo uye neruvara rwakajeka. misiyano.Iyo erythritol inoshandiswa mumidziyo yakabikwa inofanirwa kuve yakapfava kana kuti crystallized neyakatsetseka particle size (<200μm), uye zvimedu zvakanaka zvinounza kutsetseka uye kutenderera kuravira kuchigadzirwa.
3. Zvinowedzera
Erythritol inogona zvakare kushandiswa kugadzira yakanaka mhando yechigadzirwa chekuwedzera senge jamu, kirimu, butter icing uye kumwe kushongedza kwepamusoro.
A. Kuwedzera erythritol kune jamu kunogona kuwedzera chibereko chemuchero.
B. Kuwedzera erythritol kukrimu icing (mafuta akazara) haazongoderedzi makoriyori asiwo kuunza kuravira kunozorodza;apo chigadzirwa chinoshandisa erythritol, maltitol liquid uye aspartame panguva imwe chete, kukosha kwesimba kunogona kuderedzwa neanenge 50%.
4. Zvihwitsi
Ikozvino musika wemaswiti uye chokoreti wakawedzerawo kubva pakushandiswa kwekutanga kwe sucrose sechinhu chakakosha chekushandisa kusvika kune nyowani-yakaderera-shuga uye yakaderera-calorie-yakavakirwa zvigadzirwa.Mumakore achangopfuura, zvigadzirwa zvehuga zvekushanda zvakave zvakanyanyisa kuzara mumusika uye zvave zvemazuva ano epasi rose Inoshandiswa hotspot uye kutarisa kwekusimudzira kwemusika wemaswiti, mukana wemusika wakakura.Mushure mekutsvagisa kwenguva refu inoshanda, zvakaratidzwa kuti itsva inoshanda raw material erythritol inonyatsozadzisa zvinodiwa.Kuravira kwe erythritol kwakafanana neye sucrose, uye hapana chikonzero chekuwedzera zvinotapira zvakasimba zvakadai seaspartame kana saccharin.Maswiti anozobuda anotonhorera uye anotonhorera kupfuura mamwe "asiri-sucrose" candies, ane kutapira kwakachena uye hakuna kunakidza kunotevera.
5. Chokoti
Erythritol inogona nyore kutsiva sucrose muchigadzirwa uye kuderedza simba rechokoreti ne34%.Hapana imwe shuga doro inogona kupa simba rakadaro kuderedza, uye kupa chigadzirwa nekunaka kunotonhorera uye kwete-cariogenic properties.Nekuda kweiyo yakaderera hygroscopicity, erythritol inobatsira kukurira kutumbuka kweimwe shuga kana uchigadzira chokoreti.
6. Indasitiri yemishonga
Zvinhu zve erythritol, zvakadai se-anti-caries, anti-oxidation, kuchengetedza unyoro uye kusapisa, inoita kuti kushandiswa kwayo muminda yemishonga uye makemikari ezuva nezuva arambe achiwedzera.
meso-Erythritol chinhu chinongoitika chisiri checariogenic excipient chinoshandiswa mumhando dzakasiyana dzemishonga yekugadzirira, kusanganisira mune yakasimba dosage mafomu senge piritsi rekuzadza, uye mumabhandi.Yakaongororwa zvakare kuti ishandiswe muhupfu hwakaoma inhalers.Iyo zvakare inoshandiswa mune isina shuga lozenges, uye ine medicated chewing gum.meso-Erythritol inogona zvakare kushandiswa seyakanyorovesa mukunyorova granulation yakasanganiswa nemishonga inonzwa nekunyorova.Mune buccal applications, senge medicated chewing gums, inoshandiswa nekuda kwekupisa kwayo kwakashata kwemhinduro iyo inopa kutonhora kwakasimba.meso-Erythritol inoshandiswawo sechinhu chisina kuchena chinotapira mumasyrups;inoshandiswa kupa sensorial profile-modifying properties ine intense sweeteners;uye inoshandiswawo kuvhara zvisingadiwe zvinonaka.meso-Erythritol inoshandiswawo sechinhu chinotapira chisina kuchena mumishonga yemazino uye mishonga yekugezesa muromo.
