Sucrosendi disaccharide, yopangidwa ndi molekyulu imodzi ya shuga ndi molekyulu imodzi ya fructose yolumikizidwa ndi chomangira cha alpha-1, 2-glucoside. Kapangidwe kake ka mamolekyu ndi kakukulu komanso kocholowana, ndipo kamangidwe kameneka kamatsimikizira zina mwa zinthu zake, monga kutsekemera ndi kusungunuka kwake.

Sucrose imachokera makamaka ku zomera, zofala kwambiri kukhala nzimbe ndi shuga beet. Anthu mwa kukanikiza nzimbe tsinde, kuchotsa madzi, kudzera mndandanda wa kusefera, ndende, crystallization ndi njira zina kupeza sucrose makhiristo.

Monga chimodzi mwazotsekemera zodziwika bwino, sucrose imatha kupereka kukoma kwa zakudya ndi zakumwa, monga maswiti athu wamba, chokoleti, makeke, makeke ndi zina zotero.

Sucralose, yomwe imadziwika kuti sucralose, ndi mtundu wa zotsekemera zopanga zopanda ma calories komanso mphamvu zambiri. Mu 1976, mtundu watsopano wa zotsekemera unapangidwa pamodzi ndikupatsidwa chilolezo ndi kampani ya British Telly ndi yunivesite ya London, ndipo idagulitsidwa mu 1988, yomwe ndi njira yokhayo yotsekemera yomwe imakhala ndi sucrose ngati zopangira.

Sucralose ndi ufa wa crystalline woyera womwe umasungunuka kwambiri m'madzi, ndi kusungunuka kwa 28.2g / 100ml m'madzi pa 20 ° C. Ali ndi makhalidwe opanda mphamvu, kutsekemera kwakukulu ndi chitetezo chapamwamba. Sucralose imagawidwa m'njira zosiyanasiyana zophatikizira, monga njira yotetezera gulu lonse, njira yoteteza gulu limodzi (njira imodzi ya ester), njira ya biocatalysis (njira yamankhwala a enzyme), njira ya raffinose, njira ya tetrachlorose. M'moyo watsiku ndi tsiku, sucralose imagwiritsidwa ntchito muzakumwa, mkaka, zinthu zophika ndi confectionery.

Kusiyana

(1) Kukoma
Sucrose ndi chotsekemera chomwe chimagwiritsidwa ntchito kwambiri, ndipo kutsekemera kwake ndi kofanana, komwe nthawi zambiri kumatanthauzidwa kuti 1.0 (kutengera kutsekemera kwake). Kutsekemera kwake kumakhala kochepa, komwe kungapereke kutsekemera kwachilengedwe kwa chakudya, ndipo ndikodziwika bwino kwa zakudya za People's Daily, monga maswiti ndi makeke.
Sucralose ndiwotsekemera kwambiri, wotsekemera nthawi 400-800 kuposa sucrose. Izi zikutanthauza kuti sucralose yochepa kwambiri ingagwiritsidwe ntchito kukwaniritsa kutsekemera kofanana ndi kuchuluka kwa sucrose. Mwachitsanzo, pakupanga chakumwa, kachulukidwe kakang'ono ka sucralose chitha kugwiritsidwa ntchito kuti chakumwacho chikhale chokoma mokwanira.

(2) Kutentha
Sucrose imatha kupereka mphamvu mthupi la munthu, ndipo gramu iliyonse ya sucrose m'thupi la munthu imatha kukhala oxidized ndikuwola kuti ipange zopatsa mphamvu pafupifupi 4. Thupi likameza sucrose, imapangidwa ndi hydrolyzed m'matumbo kukhala shuga ndi fructose, yomwe imalowetsedwa m'magazi, omwe amagwiritsidwa ntchito ndi maselo ngati gwero lamphamvu, kapena amasinthidwa kukhala glycogen kuti asungidwe.
Sucralose imapereka pafupifupi ma calories. Chifukwa chakuti sucralose samalowa m'thupi m'chigayo cham'mimba ndipo nthawi zambiri amatuluka m'mkodzo, m'malo motsekemera anthu omwe amafunikira kuchepetsa kudya kwawo, monga odwala matenda ashuga komanso onenepa kwambiri.

(3) Chitetezo
Sucrose ndi shuga wopezeka mwachilengedwe yemwe ndi wotetezeka kuti anthu azigwiritsa ntchito moyenera. Komabe, kumwa kwambiri sucrose kungayambitse mavuto ambiri azaumoyo, monga caries mano, kuchuluka kwa shuga m'magazi, kunenepa kwambiri, ndi zina zambiri. Kudya zakudya zokhala ndi shuga wambiri kwa nthawi yayitali kungapangitsenso chiopsezo cha matenda osatha monga shuga ndi matenda amtima.
Sucralose idawunikiridwa mwamphamvu zachitetezo ndipo imawonedwa ngati yotetezeka kuti igwiritsidwe ntchito bwino. Mwachitsanzo, China idavomereza mwalamulo kugwiritsa ntchito sucralose mu 1997, United States Food and Drug Administration (FDA), European Food Safety Authority (EFSA) ndi mayiko ena ambiri ndi mabungwe avomereza sucralose ngati chowonjezera cha chakudya.
