Kugwiritsa ntchito
Sucrose imagwiritsidwa ntchito kwambiri muzakudya, zodzoladzola ndi zamankhwala, ndipo imagwiritsidwanso ntchito ngati mulingo wowunikira komanso kuzindikira.Angagwiritsidwe ntchito pokonzekera citric acid, caramel, invert shuga, mandala sopo, etc. Iwo akhoza ziletsa kukula kwa mabakiteriya pa mkulu ndende, ndipo angagwiritsidwe ntchito ngati piritsi excipient wa preservative ndi antioxidant mankhwala.The reagent sucrose ntchito kutsimikiza 1-naphthol, kulekana kwa calcium ndi magnesium ndi kukonzekera kwachilengedwenso sing'anga chikhalidwe.
Sucrose, chigawo chachikulu cha shuga patebulo, ndi mtundu wa disaccharide, womwe umakhala ndi molekyulu ya hemiacetal hydroxyl gulu la shuga ndi molekyulu ya hemiacetal hydroxyl gulu la fructose lopindika wina ndi mnzake ndikutaya madzi.Sucrose ndi wotsekemera, wopanda fungo, wosungunuka m'madzi ndi glycerol, ndipo amasungunuka pang'ono mu mowa.Ndi spinogenic, koma alibe photochromic effect.Sucrose imapezeka pafupifupi padziko lonse lapansi m'masamba, maluwa, zimayambira, mbewu ndi zipatso za mbewu.Ndiwochuluka kwambiri mu nzimbe, shuga beet ndi mapulo sap.Sucrose ili ndi kukoma kokoma ndipo ndi chakudya chofunikira komanso kukoma kokoma.Amagawidwa kukhala shuga woyera, shuga wofiirira, shuga wa rock, shuga wa rock, ndi shuga wambiri (shuga wachikasu)
Thupi katundu
Sucrose imasungunuka kwambiri m'madzi, ndipo kusungunuka kwake kumawonjezeka ndi kuwonjezeka kwa kutentha, ndipo sikuyendetsa magetsi ikasungunuka m'madzi.Sucrose imasungunukanso mu aniline, azobenzene, ethyl acetate, amyl acetate, phenol yosungunuka, ammonia yamadzimadzi, osakaniza mowa ndi madzi ndi osakaniza acetone ndi madzi, koma insoluble mu zosungunulira organic monga mafuta, petroleum, anhydrous mowa, trichloromethane. , carbon tetrachloride, carbon disulfide ndi turpentine.Sucrose ndi chinthu cha crystalline.Mphamvu yokoka ya makhiristo oyera a sucrose ndi 1.5879, ndipo mphamvu yokoka ya yankho la sucrose imasiyanasiyana kutengera ndende ndi kutentha.Kusinthasintha kwapadera kwa sucrose ndi +66.3 ° mpaka +67.0 °.
Mankhwala katundu
Mayankho a sucrose ndi sucrose pansi pa kutentha, asidi, alkali, yisiti, ndi zina zambiri, amatulutsa mitundu yosiyanasiyana yamankhwala.Zomwe zimachitika sizimangowonongeka mwachindunji ndi sucrose, komanso kupanga zinthu zomwe zimawononga kupanga shuga.
Sucrose yonyezimira ikatenthedwa kufika 160 ° C, imawola ndikusungunuka kukhala madzi okhuthala komanso owoneka bwino, kenako imatsitsimutsanso ikakhazikika.Kutentha kwanthawi yayitali, sucrose imawonongeka kukhala glucose ndi defructose.Pa kutentha kwakukulu kwa 190-220 ° C, sucrose imachotsedwa madzi ndi kusinthidwa kukhala caramel.Kutentha kwina kwa caramel kumapanga carbon dioxide, carbon monoxide, acetic acid ndi acetone.Pansi pa chinyezi, sucrose imawola pa 100 ° C, kutulutsa madzi ndikupangitsa mdima.Sucrose solution ikatenthedwa mpaka kuwira kwanthawi yayitali, sucrose yosungunuka imawola pang'onopang'ono kukhala glucose ndi fructose, mwachitsanzo, kutembenuka kumachitika.Ngati yankho la sucrose litatenthedwa pamwamba pa 108 ℃, limapangidwa ndi hydrolyzed mwachangu, ndipo kuchuluka kwa shuga kumakhala kofunikira kwambiri.Chitsulo chomwe chimagwiritsidwa ntchito mu chotengera chowira chimakhudzanso kuchuluka kwa kutembenuka kwa sucrose.Mwachitsanzo, kutembenuka kwa sucrose solution muzotengera zamkuwa ndikokulirapo kuposa zotengera zasiliva, ndipo zotengera zamagalasi sizigwira ntchito.
