Hoʻohana nui ʻia ʻo Sucrose i ka meaʻai, nā mea hoʻonaninani a me nā lāʻau lapaʻau, a hoʻohana ʻia hoʻi ma ke ʻano he maʻamau no ka nānā ʻana a me ka ʻike.Hiki ke hoʻohana ʻia e hoʻomākaukau i ka waikawa citric, caramel, invert sugar, transparent soap, etc. Hiki ke kāohi i ka ulu ʻana o ka bacteria ma ke kiʻekiʻe kiʻekiʻe, a hiki ke hoʻohana ʻia e like me ka papa excipient o ka preservative a me ka antioxidant i ka lāʻau lapaʻau.Hoʻohana ʻia ka reagent sucrose no ka hoʻoholo ʻana i ka 1-naphthol, ka hoʻokaʻawale ʻana o ka calcium a me ka magnesium a me ka hoʻomākaukau ʻana i ke ʻano moʻomeheu biological.
ʻO Sucrose, ka mea nui o ka papa kōpaʻa, he ʻano disaccharide, aia i loko o kahi mole o ka hui hemiacetal hydroxyl o ka glucose a me kahi mole o ka hui hemiacetal hydroxyl o ka fructose i hoʻopaʻa ʻia me kekahi a me ka dehydrated.He ʻono ka Sucrose, ʻaʻala ʻole, hiki ke hoʻoheheʻe ʻia i ka wai a me ka glycerol, a hiki ke hoʻoheheʻe iki ʻia i ka waiʻona.He spinogenic, akā ʻaʻohe hopena photochromic.ʻIke ʻia ʻo Sucrose ma nā lau, nā pua, nā ʻōpala, nā ʻanoʻano a me nā hua o ke aupuni mea kanu.Nui loa ia i ke kō, ke kō a me ke kohu maple.He ʻono ʻono ka Sucrose a he meaʻai koʻikoʻi a me ka mea ʻono.Ua māhele ʻia ʻo ia i ke kō keʻokeʻo, ke kō ʻeleʻele, ke kō pōhaku, ke kō pōhaku, a me ke kō koʻa (ke kō melemele)

Hiki ke hoʻoheheʻe ʻia ʻo Sucrose i ka wai, a piʻi aʻe kona solubility me ka piʻi ʻana o ka mahana, ʻaʻole ia e lawe i ka uila ke hoʻoheheʻe ʻia i ka wai.Hiki ke hoʻoheheʻe ʻia ʻo Sucrose i ka aniline, azobenzene, ethyl acetate, amyl acetate, melted phenol, ammonia wai, ka hui ʻana o ka waiʻona a me ka wai a me ka hui ʻana o ka acetone a me ka wai, akā ʻaʻole hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe e like me ka ʻaila, ka ʻaila, anhydrous alcohol, trichloromethane , kalapona tetrachloride, kalapona disulfide a me ka turpentine.ʻO ka sucrose kahi mea crystalline.ʻO 1.5879 ka umekaumaha kikoʻī o nā kristal sucrose maʻemaʻe, a ʻokoʻa ka gravity o ka solution sucrose ma muli o ka ʻike a me ka mahana.ʻO ka hoʻololi kikoʻī o ka sucrose he +66.3° a i +67.0°.

ʻO Sucrose a me ka sucrose solution ma lalo o ka hana o ka wela, ka waikawa, ka alkali, ka hū, a me nā mea ʻē aʻe, e hoʻopuka i nā ʻano like ʻole.ʻAʻole ka hopena o ka hopena i ka nalowale pololei ʻana o ka sucrose, akā i ka hana ʻana i nā mea ʻino i ka hana kō.
Ke hoʻomehana ʻia ka sucrose crystallized i 160°C, e hoʻoheheʻe ʻia a hoʻoheheʻe ʻia i loko o kahi wai mānoanoa a ʻalohilohi, a laila recrystallize i ka wā i maʻalili.Hoʻonui ʻia ka manawa hoʻomehana, hoʻoheheʻe ʻia ka sucrose i ka glucose a me ka defructose.Ma kahi kiʻekiʻe o ka mahana o 190-220 ° C, e hoʻoheheʻe ʻia ka sucrose a hoʻopaʻa ʻia i ka caramel.ʻO ka hoʻomehana hou ʻana o ka caramel e hoʻopuka i ka carbon dioxide, carbon monoxide, acetic acid a me ka acetone.Ma lalo o nā kūlana haʻahaʻa, hoʻoheheʻe ʻia ka sucrose ma 100 ° C, hoʻokuʻu i ka wai a pōʻeleʻele ke kala.Ke hoʻomoʻa ʻia ka hopena sucrose a hiki i ka paila ʻana ma ke kaomi o ka lewa no ka manawa lōʻihi, hoʻoheheʻe lohi ka sucrose i hoʻoheheʻe ʻia i ka nui like o ka glucose a me ka fructose, ʻo ia hoʻi, hoʻololi ʻia.Inā wela ka hopena sucrose ma luna o 108 ℃, e hydrolyzed wikiwiki ia, a ʻoi aku ka nui o ka hopena o ke kō, ʻoi aku ka nui o ka hopena hydrolysis.ʻO ka mea metala i hoʻohana ʻia i loko o ka ipu e hoʻolapalapa ai kekahi hopena i ka wikiwiki o ka hoʻololi ʻana i ka sucrose.ʻO kahi laʻana, ʻoi aku ka nui o ka hoʻololi ʻana o ka sucrose solution i loko o nā ipu keleawe ma mua o nā kīʻaha kālā, a he liʻiliʻi ka hopena o nā kīʻaha aniani.
