Sucroseis a disaccharide, inosanganisira imwe molekuru yeglucose uye imwe molekuru yefructose yakabatana nealpha-1, 2-glucoside bond. Chimiro chayo chemorekuru chakakura uye chakaoma kunzwisisa, uye chimiro ichi chinotarisa zvimwe zvezvimiro zvayo, sekutapira nekunyungudika.

Sucrose inouya zvakanyanya kubva mumiti, iyo inowanzova nzimbe uye shuga beet. Vanhu nekutsikirira dzinde renzimbe, vanobvisa muto, kuburikidza nekutevedzana kwekusefa, kusungirira, crystallization uye mamwe maitiro ekuwana sucrose makristasi.

Seimwe yeanonyanya kutapira, sucrose inogona kupa kutapira kune zvekudya uye zvinwiwa, senge yedu yakajairika candy, chokoreti, makuki, makeke uye zvichingodaro.

Sucralose, inowanzozivikanwa se sucralose, imhando yekutapira yekugadzira isina macalorie uye simba rakawanda. Muna 1976, rudzi rutsva rwekutapira rwakagadzirwa pamwe chete uye rwakapihwa patent nekambani yeBritish Telly neYunivhesiti yeLondon, uye yakaiswa mumusika muna 1988, inova ndiyo yega yekutapira inoshanda ine sucrose seyakabikwa.

Sucralose inonzi white crystalline powder inonyanya kunyunguduka mumvura, ine solubility ye 28.2g / 100ml mumvura pa 20 ° C. Iine maitiro ekushaya simba, kutapira kwakanyanya uye kuchengetedzwa kwepamusoro. Sucralose yakakamurwa kuva nzira dzakasiyana-siyana dzekubatanidza, dzakadai senzira yekudzivirira boka rose, nzira yekudzivirira yeboka rimwe chete (single ester method), biocatalysis nzira (enzyme chemical method), raffinose nzira, tetrachlorose nzira. Muhupenyu hwezuva nezuva, sucralose inoshandiswa muzvinwiwa, zvigadzirwa zvemukaka, zvakabikwa uye confectionery.

Distinction

(1) Kutapira
Sucrose inowanzo shandiswa zvinotapira, uye kutapira kwayo chiyero chehukama, chinowanzotsanangurwa se 1.0 (zvichienderana nekutapira kwayo). Kutapira kwayo kunenge kwakadzikira, izvo zvinogona kupa kutapira kwechisikigo kwechikafu, uye inzvimbo yakajairika yekutapira muChikafu chePeople's Daily, senge zvihwitsi nemakeke.
Sucralose inotapira kwazvo, 400-800 nguva inotapira se sucrose. Izvi zvinoreva kuti ishoma chete huwandu hwe sucralose hunogona kushandiswa kuwana kutapira kwakafanana nehuwandu hwesucrose. Semuenzaniso, mukugadzirwa kwechinwiwa, huwandu hushoma hwe sucralose hunogona kushandiswa kuita chinwiwa chinotapira zvakakwana.

(2) Kupisa
Sucrose inogona kupa simba kumuviri wemunhu, uye giremu yega yega ye sucrose mumuviri wemunhu inogona kuve yakanyatso oxidized uye yakaora kuti ibudise zviuru zvina zvemacalorie. Kana muviri uchinge wadya sucrose, inoiswa hydrolyzed mudumbu rekudya kuita glucose uye fructose, iyo inobva yanyudzwa muropa, inoshandiswa nemasero sechitubu chesimba, kana kushandurwa kuita glycogen yekuchengetedza.
Sucralose inopa anenge asina macalorie. Nekuda kwekuti hainyanyi kunyura muhurongwa hwekugaya kwemuviri uye kazhinji inoburitswa muweti, sucralose inotapira inotsiva vanhu vanofanirwa kudzora macalorie avo ekudya, sevanorwara neshuga uye vakafutisa.

(3) Chengetedzo
Sucrose ishuga inongoitika yakachengeteka kuti ishandiswe nevanhu muhuwandu hwakajairika. Nekudaro, kunyanyisa kunwa sucrose kunogona kutungamira kune akati wandei matambudziko ehutano, akadai semazino caries, yakakwira shuga yeropa, kufutisa, nezvimwe. Kudya kwehuga kwenguva refu kunogonawo kuwedzera njodzi yezvirwere zvisingaperi seshuga uye chirwere chemoyo.
Sucralose yakaitwa ongororo yakasimba yekuchengetedza uye inoonekwa seyakachengeteka kushandiswa kwakajairwa. Semuenzaniso, China yakabvumidza zviri pamutemo kushandiswa kwe sucralose muna 1997, United States Food and Drug Administration (FDA), European Food Safety Authority (EFSA) nedzimwe nyika dzakawanda nemasangano akabvumidza sucralose sekuwedzera kwechikafu.
