Sucrose e sebelisoa haholo lijong, litlolong le meriana, hape e sebelisoa e le mokhoa oa ho hlahloba le ho lemoha.E ka sebelisoa ho lokisa citric acid, caramel, invert tsoekere, sesepa pepeneneng, joalo-joalo E ka thibela kholo ea libaktheria ka mahloriso a phahameng, 'me e ka sebelisoa e le letlapa excipient ea preservative le antioxidant meriana.Reagent sucrose e sebelisoa bakeng sa qeto ea 1-naphthol, karohano ea calcium le magnesium le ho lokisoa ha setso sa baeloji.
Sucrose, e leng karolo ea mantlha ea tsoekere ea tafoleng, ke mofuta oa disaccharide, e nang le molek'hule ea sehlopha sa hemiacetal hydroxyl ea tsoekere le molek'hule ea sehlopha sa hemiacetal hydroxyl ea fructose e kopantsoeng 'me e felloa ke metsi.Sucrose e monate, ha e na monko, e qhibiliha ka metsing le glycerol, 'me e qhibiliha hanyenyane ka joala.Ke spinogenic, empa ha e na phello ea photochromic.Sucrose e batla e fumaneha hohle makhasi, lipalesa, stems, peo le litholoana tsa 'muso oa semela.E fumaneha ka bongata 'moba, beet ea tsoekere le lero la maple.Sucrose e na le tatso e monate ebile ke lijo tsa bohlokoa le tatso e monate.E arotsoe ka tsoekere e tšoeu, tsoekere e sootho, tsoekere ea rock, tsoekere ea rock, le tsoekere e mahoashe (tsoekere e mosehla)
Lintho tsa 'mele
Sucrose e qhibiliha haholo ka metsing, 'me ho qhibiliha ha eona ho eketseha ka ho eketseha ha mocheso,' me ha e tsamaise motlakase ha e qhibiliha ka metsing.Sucrose e boetse e qhibiliha ho aniline, azobenzene, ethyl acetate, amyl acetate, phenol e qhibilihisitsoeng, ammonia ea metsi, motsoako oa joala le metsi le motsoako oa acetone le metsi, empa ha e qhibilihe ka har'a metsoako ea lintho tse phelang tse kang peterole, petroleum, joala bo anhydrous, trichloromethane. , carbon tetrachloride, carbon disulfide le turpentine.Sucrose ke ntho ea kristale.Matla a ikhethileng a likristale tse hloekileng tsa sucrose ke 1.5879, 'me matla a khoheli a tharollo ea sucrose a fapana ho latela mohopolo le mocheso.Potoloho e khethehileng ea sucrose ke +66.3 ° ho +67.0 °.
Lintho tsa lik'hemik'hale
Litharollo tsa sucrose le sucrose tlas'a ketso ea mocheso, asiti, alkali, tomoso, joalo-joalo, li hlahisa mefuta e fapaneng ea karabelo ea lik'hemik'hale.Karabelo ha e felle feela ka tahlehelo e tobileng ea sucrose, empa hape le tlhahiso ea lintho tse kotsi tlhahisong ea tsoekere.
Ha crystallized sucrose e futhumatsoa ho 160 ° C, e tla bola ka mocheso 'me e qhibilihe ho ba mokelikeli o motenya le o bonaletsang, ebe e bososela ha e pholisitsoe.Nako ea ho futhumatsa e a atolosoa, sucrose e qhibiliha ho ba tsoekere le defructose.Ka mocheso o phahameng oa 190-220 ° C, sucrose e tla felloa ke metsi 'me e kenngoe ka caramel.Ho futhumatsa ho eketsehileng ha caramel ho hlahisa carbon dioxide, carbon monoxide, acetic acid le acetone.Tlas'a maemo a mongobo, sucrose e bola ka 100 ° C, e lokolla metsi le ho fifatsa 'mala.Ha tharollo ea sucrose e futhumatsoa ho bela ka khatello ea sepakapaka nako e telele, sucrose e qhibilihisitsoeng e senyeha butle-butle ka tekanyo e lekanang ea tsoekere le fructose, ke hore, phetoho e etsahala.Haeba tharollo ea sucrose e futhumatsoa ka holimo ho 108 ℃, e tla kenngoa ka hydrolyzed ka potlako, 'me ha motsoako o moholo oa tharollo ea tsoekere, phello ea hydrolysis e le ea bohlokoa le ho feta.Lisebelisoa tsa tšepe tse sebelisoang ka sekepeng se belang le tsona li na le phello ho sekhahla sa phetoho ea sucrose.Mohlala, phetoho ea tharollo ea sucrose lijaneng tsa koporo e kholo haholo ho feta lijaneng tsa silevera, 'me lijana tsa khalase ha li na phello e nyane.
