ʻO D-Sorbitol (CAS: 50-70-4) kahi waiʻona polyhydric sugar non-volatile.He paʻa kemika a ʻaʻole maʻalahi ke hoʻoheheʻe ʻia e ka ea.He maʻalahi hiki ke hoʻoheheʻe ʻia i ka wai, ethanol wela, methanol, isopropanol, butanol alcohol, cyclohexanol, phenol, acetone, acetic acid a me dimethyl formamide.ʻAʻole maʻalahi ka fermented e nā ʻano microorganism like ʻole a loaʻa kahi pale wela maikaʻi loa.Ua hoʻokaʻawale mua ʻia mai ka mauna strawberry e ka Boussingault (French) et al.He 6 a hiki i ka 7 ka pH waiwai o ka wai hoʻonā wai. He isomer ia o ka mannitol, ka waiʻona Taylor, a me ka waiʻona galactose.Loaʻa iā ia kahi ʻono ʻono hōʻoluʻolu me ka ʻono he 65% o ka sucrose.Loaʻa iā ia ka hiki ke hoʻoheheʻe ʻia me ka haʻahaʻa haʻahaʻa haʻahaʻa a loaʻa i nā hopena ākea loa i ka meaʻai, cosmetic, pharmaceutical field.Ke hoʻohana ʻia i ka meaʻai, hiki iā ia ke pale i ka maloʻo ʻana o ka meaʻai, ʻelemakule, a hiki ke hoʻolōʻihi i ke ola o nā huahana a me ka pale pono ʻana i ka ua o nā kō a me nā paʻakai i loko o nā meaʻai a pēlā e mālama ai i ke koena ikaika o ka ʻono, ʻawaʻawa a me ka ʻawaʻawa. hoʻonui i ka ʻono meaʻai.Hiki ke synthesize mai ka hydrogenation o ka glucose ma lalo o ka hoʻomehana a me ke kaomi kiʻekiʻe me ka noho ʻana o ka nickel catalyst.
Nā hoʻohana nui o D-Sorbitol Powder
1. ʻOihana Kemika o kēlā me kēia lā
Hiki ke hoʻohana ʻia ʻo Sorbitol ma ke ʻano he excipient, moisturizing agents, a me nā antifreeze agents i ka toothpaste, me ka nui i hoʻohui ʻia a hiki i ka 25 a 30%.Hiki i kēia ke kōkua i ka mālama ʻana i ka lubrication, kala, a me ka ʻono maikaʻi no ka paʻi.I ka cosmetics kahua, ua hoʻohana 'ia ma ke ano he anti-drying agent (substitute glycerol) hiki ke hoʻonui i ka kikoo a me ka lubricity o ka emulsifier, a pela no ka mālama lōʻihi;Sorbitan esters a me sorbitan fatty acid ester a me kona ethylene oxide adducts i loaʻa ka pōmaikaʻi o ka ʻili liʻiliʻi i hoʻohana nui ʻia i ka ʻoihana hoʻonaninani.
2. Ka ʻOihana Meaʻai
ʻO ka Sorbitol kahi mea hygroscopic, mālama wai i hoʻohana ʻia i ka hana ʻana i ka nau a me nā mea ʻono e mālama i ka meaʻai palupalu, hoʻomaikaʻi i ka ʻiʻo a hōʻemi i ka paʻakikī o ke one.Hoʻohana nui ʻia i ka meaʻai, hoʻohana ʻia i loko o ka hana ʻana i ka candy nonsugar a me ka papa mālama ola kino (loaʻa kahi ʻāpana).ʻO ka hoʻohui ʻana i ka sorbitol i loko o nā meaʻai hiki ke pale i ka maloʻo ʻana o ka meaʻai a mālama i ka meaʻai i mea hou a palupalu.He hopena koʻikoʻi ka hoʻohana ʻana i ka keke palaoa.ʻO ka mea ʻono a i ʻole ka lāʻau kūʻokoʻa o ka nau ʻaʻa ʻole ke kō, ka hau kokoleka no ka hana ʻana i ka ice cream a me ka candy, i hoʻohana ʻia i nā mea inu, candy, baking a me nā meaʻai ʻē aʻe.
ʻOi aku ka ʻono o ka sorbitol ma mua o ka sucrose, a ʻaʻole hiki ke hoʻohana ʻia e kekahi bacteria.He mea koʻikoʻi ia no ka hana ʻana i ka candy me ke kō ʻole a me nā ʻano meaʻai anti-caries.No ka mea ʻaʻole i hoʻonui ka metabolism o ka huahana i ka hoʻonui ʻana i ke kō koko, hiki ke hoʻohana ʻia ma ke ʻano he mea ʻono a me ka meaʻai meaʻai no ka meaʻai o nā maʻi me ka maʻi diabetes.
ʻAʻole i loaʻa i ka Sorbitol kahi pūʻulu aldehyde a ʻaʻole maʻalahi i ka oxidized.ʻAʻole e loaʻa ka hopena Maillard me nā ʻakika amino ma ka hoʻomehana ʻana.Loaʻa iā ia kekahi hana physiological.Hiki iā ia ke pale i ka denaturation o nā carotenoids a me nā momona momona a me ka protein;ʻO ka hoʻohui ʻana i kēia huahana i ka waiū paʻa hiki ke hoʻolōʻihi i ke ola o ka papa;hiki ke hoʻohana ʻia no ka hoʻomaikaʻi ʻana i ka waihoʻoluʻu, ka ʻono a me ka ʻono o ka ʻōpū liʻiliʻi a he hopena stabilizing koʻikoʻi a me ka hopena mālama lōʻihi i ka pate iʻa.Hiki ke ʻike ʻia ka hopena like i ka jam.
3. ʻO ka ʻoihana lāʻau lapaʻau
Hiki ke hoʻohana ʻia ʻo Sorbitol ma ke ʻano he mea maka i ka huaora C;hiki ke hoʻohana ʻia e like me ka syrup hānai, nā wai injection, a me nā mea maka o ka papa lāʻau lapaʻau;ma ke ʻano he mea hoʻopuehu lāʻau a me nā mea hoʻopihapiha, cryoprotectants, anti-crystallizing agent, lāʻau stabilizers, wetting agents, capsules plasticized agents, sweetening agents, and ointment matrix.
Hoʻohana pū ʻia ʻo Sorbitol i ka hana ʻana i nā capsules softgel no ka mālama ʻana i ka nui o nā lāʻau lapaʻau wai.
4. Ka 'Oihana Kimia
Hoʻohana pinepine ʻia ʻo Sorbitol abietin ma ke ʻano he mea maka no ka uhi ʻana o ka hale hana maʻamau, hoʻohana ʻia e like me nā plasticizers a me nā lubricants no ka noi ʻana i ka resin polyvinyl chloride a me nā polymers ʻē aʻe.
Hiki iā ia mai ka paʻakikī me ka hao, ke keleawe, a me ka alumini ion i loko o ka hopena alkaline e hoʻopili ʻia i ka holoi a me ka bleaching i ka ʻoihana textile.
ʻO ka hoʻohana ʻana i ka sorbitol a me ka propylene oxide ma ke ʻano he mea hoʻomaka hiki ke hana i ka huʻa polyurethane paʻa a loaʻa kekahi mau mea pale ahi.
5. ʻO ka ʻoihana hoʻonaninani:
I loko o ka cosmetics oihana laha loa noi.
ʻO ka sorbitol kekahi ʻano o nā kemika ʻoihana versatility, loaʻa iā ia ka hana ākea loa i ka meaʻai, kemika i kēlā me kēia lā, lāʻau lapaʻau a me nā mea ʻē aʻe, a hiki ke hoʻohana ʻia e like me ka ʻono ʻono, excipient, antiseptic etc. haʻahaʻa wela wela, haʻahaʻa kō, kiaʻi mai ka hopena a pēlā aku.
6. Hiki ke hoʻohana ʻia ka D-Sorbitol i mea ʻono no nā maʻi maʻi diabetes.Loaʻa iā ia ka mālama wela maikaʻi, ka pale ʻana i ka waikawa a me ka non-fermentability.
7. Nā mea ʻē aʻe:
No ka hoʻololi ʻana i ka glycerin e hana i ka toothpaste, mannitol polyurethane, mannitol anhydride oleate, electrolytic solution of electrolytic capacitors, a me kahi moʻomeheu maikaʻi no kekahi mau microorganisms.
