Taupānga
Ka whakamahia nuitia te Sucrose i roto i te kai, te whakapaipai me te rongoa, ka whakamahia ano hei paerewa mo te tātari me te rapu.Ka taea te whakamahi ki te whakarite i te waikawa citric, caramel, te huka hurihuri, te hopi maramara, me etahi atu. Ka taea te aukati i te tipu o te huakita i te kukū teitei, ka taea te whakamahi hei papa taapiri mo te rongoa me te antioxidant i roto i te rongoa.Ka whakamahia te reagent sucrose mo te whakatau i te 1-naphthol, te wehenga o te konupūmā me te konupora me te whakarite i te reo ahurea koiora.
Ko Sucrose, te waahanga matua o te huka tepu, he momo disaccharide, kei roto he ngota ngota o te roopu hydroxyl hemiacetal o te glucose me tetahi ngota ngota o te roopu hydroxyl hemiacetal o te fructose kua whakapoapoa tetahi ki tetahi ka maroke.He reka te Sucrose, he hongi, he wairewa ki te wai me te glycerol, me te rewa paku ki te waipiro.He spinogenic, engari kaore he paanga photochromic.Ko te Sucrose ka kitea i roto i nga rau, nga puawai, nga kakau, nga kakano me nga hua o te tipu tipu.He nui rawa i roto i te huka, te huka pīti me te wai maple.He reka te reka o te Sucrose, he kai nui me te kakara reka.Ka wehewehea ki te huka ma, te huka parauri, te huka toka, te huka toka, me te huka para (te huka kowhai)
Ngā āhuatanga ā-tinana
He tino wairewa te Sucrose ki te wai, ka piki ake te whakamaaramatanga i te pikinga o te pāmahana, karekau hoki e kawe hiko ina rewa ki te wai.Ko te Sucrose ano ka whakarewahia i roto i te aniline, azobenzene, ethyl acetate, amyl acetate, phenol rewa, haukini wai, ranunga o te waipiro me te wai me te ranunga o te acetone me te wai, engari he kore e rewa i roto i nga whakarewa pararopi penei i te penehīni, te hinu, te waipiro anhydrous, trichloromethane , waro tetrachloride, waro disulfide me te turpentine.Ko te Sucrose he matū tioata.Ko te taumahatanga motuhake o nga tioata sucrose parakore he 1.5879, he rereke te taumahatanga o te otinga sucrose i runga i te kukū me te pāmahana.Ko te hurihanga motuhake o te sucrose he +66.3° ki te +67.0°.
Ngā āhuatanga matū
Ko nga wairewa Sucrose me te sucrose i raro i te mahi o te wera, te waikawa, te kawakore, te rewena, me etahi atu, ka whakaputa i nga momo tauhohenga matū rereke.Ko te tauhohenga ko te kore noa o te ngaronga o te sucrose, engari ko te hanga o nga matū e kino ana ki te hanga huka.
Ina whakamahanahia te sucrose ki te 160°C, ka waiariki ka pirau, ka rewa ki roto i te wai matotoru me te maramara, katahi ka whakamatao ina whakamatao.Ka roa te wa whakamahana, ka pirau te sucrose ki te hukahuka me te deructose.I te teitei ake o te mahana o te 190-220°C, ka whakamakukuhia te sucrose ka whakamatao ki te karamere.Ko te whakamahana ake o te karamere ka puta te waro, te waro monoxide, te waikawa acetic me te acetone.I raro i te makuku, ka pirau te sucrose i te 100°C, ka tuku te wai me te whakapouri i te tae.Ina whakamahanahia te wairewa sucrose ki te koropuputanga i te pehanga hau mo te wa roa, ka pohehe te sucrose rewa ki roto i te rite o te huka me te fructose, ara, ka puta te huringa.Mena ka werahia te wairewa sucrose ki runga ake i te 108 ℃, ka tere te hauwai, ka nui ake te kukū o te wairewa huka, ka nui ake te hua o te hauwai.Ko nga mea whakarewa e whakamahia ana i roto i te ipu kohua ka whai paanga ano ki te tere o te hurihanga sucrose.Hei tauira, ko te hurihanga o te wairewa sucrose i roto i nga ipu parahi he nui ake i nga oko hiriwa, a he iti te painga o nga oko karaihe.
