Application
Sucrose inoshandiswa zvakanyanya mukudya, zvizorwa uye mushonga, uye inoshandiswawo sechiyero chekuongorora nekuona.Inogona kushandiswa kugadzirira citric acid, caramel, invert shuga, sipo yakajeka, nezvimwewo. Inogona kutadzisa kukura kwebhakitiriya pahuwandu hwehuwandu, uye inogona kushandiswa sepiritsi excipient yepreservative uye antioxidant mumishonga.Iyo reagent sucrose inoshandiswa kugadzirisa 1-naphthol, kupatsanurwa kwecalcium uye magnesium uye kugadzirira biological tsika svikiro.
Sucrose, chikamu chikuru cheshuga yepatafura, imhando ye disaccharide, iyo inosanganisira molecule yehemiacetal hydroxyl boka reglucose uye molecule yehemiacetal hydroxyl boka refructose rakanyungudutswa pamwe chete uye rakapera mvura.Sucrose inotapira, isinganhuhwi, inonyungudika mumvura uye glycerol, uye inonyungudika zvishoma mudoro.Iyo inonzi spinogenic, asi haina photochromic effect.Sucrose inenge inowanikwa pasi rose mumashizha, maruva, madzinde, mhodzi uye michero yeumambo hwemiti.Iyo inonyanya kuwanda munzimbe, shuga beet uye maple sap.Sucrose ine kuravira kunotapira uye chikafu chakakosha uye kunhuhwirira kunotapira.Yakakamurwa kuita shuga chena, shuga yebrown, shuga yedombo, shuga yedombo, uye shuga yakakora (yellow sugar)
Zvinhu zvenyama
Sucrose inonyanya kunyungudika mumvura, uye kunyungudika kwayo kunowedzera nekuwedzera kwekushisa, uye haifambisi magetsi kana yakanyungudutswa mumvura.Sucrose zvakare inonyungudika mu aniline, azobenzene, ethyl acetate, amyl acetate, yakanyunguduka phenol, liquid ammonia, musanganiswa wedoro nemvura uye musanganiswa weacetone nemvura, asi haigadzirike mu organic solvents se peturu, petroleum, anhydrous alcohol, trichloromethane. , carbon tetrachloride, carbon disulfide uye turpentine.Sucrose chinhu chine crystalline.Iyo chaiyo giravhiti yeakachena sucrose makristasi ndeye 1.5879, uye iyo chaiyo giravhiti ye sucrose mhinduro inosiyana zvichienderana nekusangana uye tembiricha.Iyo chaiyo kutenderera kwe sucrose ndeye +66.3 ° kusvika +67.0 °.
Chemical properties
Sucrose uye sucrose mhinduro pasi pechiito chekupisa, asidhi, alkali, mbiriso, nezvimwewo, inoburitsa akasiyana akasiyana maitiro emakemikari.Kuita hakungogumiri mukurasikirwa kwakananga kwe sucrose, asiwo mukugadzirwa kwezvinhu zvinokuvadza kugadzirwa kweshuga.
Kana crystallized sucrose ichidziya kusvika 160°C, inonyungudika nekunyunguduka kuita mvura yakakora uye yakajeka, yobva yaita recrystalline kana yatonhodzwa.Nguva yekupisa inowedzerwa, sucrose yakasvibiswa kuva glucose uye defructose.Pakupisa kwepamusoro kwe190-220 ° C, sucrose ichasvibiswa uye yakanyungudutswa mu caramel.Kuwedzera kupisa kwe caramel kunogadzira kabhoni dhaikisaidhi, kabhoni monoxide, acetic acid uye acetone.Pasi pemamiriro emvura, sucrose inoora pa 100 ° C, ichibudisa mvura uye ichisvibisa ruvara.Kana sucrose solution ichipisa kusvika pakuvira pamhepo yemhepo kwenguva yakareba, sucrose yakanyungudutswa inoora zvishoma nezvishoma kuita zviyero zvakaenzana zveglucose uye fructose, kureva, kutendeuka kunoitika.Kana iyo sucrose solution ikapisa pamusoro pe108 ℃, inozoitwa hydrolyzed nekukurumidza, uye iyo yakanyanya kuwanda kweshuga mhinduro, iyo inonyanya kukosha iyo hydrolysis maitiro.Iyo simbi inoshandiswa mumudziyo wekubikira inewo mhedzisiro pachiyero chekushandura sucrose.Semuenzaniso, kutendeuka kwe sucrose solution mumidziyo yemhangura yakakura kudarika mumidziyo yesirivha, uye midziyo yegirazi ine zvishoma.
