tartaric acids yog cov tebchaw uas feem ntau pom hauv cov nroj tsuag ntiaj teb. Cov no tuaj yeem yog cov isomers dawb lossis acid ntsev. Lub hauv paus tseem ceeb ntawm cov khoom no yog txiv hmab txiv ntoo siav. Tartar pob zeb, nyob rau hauv lwm yam lus, poov tshuaj sparingly soluble ntsev, yog tsim thaum lub sij hawm fermentation ntawm ib tug haus dej los ntawm berries. Cov khoom noj khoom haus no muaj npe E334. Nws tau txais feem ntau los ntawm cov khoom lag luam theem nrab ntawm kev ua cawv.
Tartaric acid: mis thiab ntau yam
Tartaric acid yog hygroscopic crystal uas tsis muaj ntxhiab tsw lossis xim. Txawm li cas los, cov khoom muaj ib tug pronounced qaub saj. Txhua yam ntawm tartaric acid yog soluble hauv dej, nrog rau hauv ethyl cawv. Cov tshuaj tiv thaiv ntau dua rau aliphatic hydrocarbons, benzene thiab ether. Cov tshuaj formula ntawm no compound yog:
Tartaric acid tshwm sim li 4 isomers. Qhov no yog vim qhov sib luag thiab sib npaug ntawm cov kua qaub carboxyls, hydrogen ions thiab hydroxyl residues. Nov yog:
- D-tartaric, hauv lwm lo lus - tartaric acid.
- L- cawacid.
- Anti-wine, hauv lwm lo lus - mesotartaric acid.
- Tataric acid, uas yog sib xyaw ntawm tartaric acids L- thiab D-.
Lub cev muaj zog
Tartaric acids zoo ib yam hauv cov khoom siv tshuaj. Txawm li cas los xij, lawv txawv kiag li thiab muaj qhov sib txawv tseem ceeb hauv lub cev tsis muaj zog. Piv txwv li, tartaric acids D- thiab L- pib yaj ntawm qhov kub ntawm 140 ° C, txiv hmab txiv ntoo acid - los ntawm 240 txog 246 ° C, meso-tartaric acid - 140 ° C.
Raws li kev solubility, thawj ob lub tebchaw yog zoo heev soluble nyob rau hauv dej, hos lwm yam yog resistant rau ya raws.
Ntshav tartaric acid
Tartaric acid tuaj yeem tsim tsuas yog ob hom ntsev: acidic thiab nruab nrab. Cov tshuaj ntawm hom tom kawg tuaj yeem ua tiav hauv dej. Txawm li cas los xij, thaum immersed hauv caustic alkali, lawv tsim Rochelle crystals. Acid monosubstituted acids tsis zoo soluble hauv cov kua. Qhov no siv tsis tau tsuas yog rau cov dej, tab sis kuj rau cov ntsuj plig thiab cawv txiv hmab. Lawv maj mam nyob ntawm phab ntsa ntawm cov hlab ntsha. Cov ntsiab lus tau ua tib zoo tshem tawm thiab siv los tsim cov organic acid.
Raws li tartar, nws pom tsis tau tsuas yog nyob rau hauv cov kua txiv hmab txiv ntoo, tab sis kuj nyob rau hauv nectars nrog pulp, thiab nyob rau hauv pastes ua los ntawm txiv hmab txiv ntoo.
Tus nqi txhua hnub
Tartaric acids tsuas yog tsim nyog rau lub cev nrog cov kab mob keeb kwm yav dhau los, kev ua haujlwm ntawm lub plab zom mov, kev ntxhov siab tas li, nrog rau lub plab acidity tsawg.
Cov tshuaj no muaj nyob rau hauv acidictxiv hmab txiv ntoo. Qhov siab tshaj plaws ntawm tartaric acid yog concentrated nyob rau hauv rhubarb, papaya, lingonberries, quince, pomegranates, cherries, gooseberries, dub currants, txiv qaub, txiv kab ntxwv, avocados, tangerines, cherries, txiv apples thiab txiv hmab txiv ntoo.
Nrog rau kev noj zaub mov kom raug thiab sib npaug, qhov xav tau txhua hnub rau cov khoom sib xyaw no tau them tag nrho. Rau kev ua haujlwm ntawm lub cev, cov txiv neej xav tau los ntawm 15 mus rau 20 milligrams ntawm tartaric acid, cov poj niam - los ntawm 13 mus rau 15 milligrams, thiab cov me nyuam - los ntawm 5 mus rau 12 milligrams.
Dab tsi yog qhov tseem ceeb tartaric acid
Cov khoom ntawm tartaric acid yog qhov nyuaj rau overestimate. Cov compound no muaj qhov tseem ceeb ntawm kev lom neeg. Tartaric acid:
- Tons the heart muscle.
- Zoo cov hlab ntsha.
- Txhawb nqa collagen synthesis.
- nce ruaj khov thiab elasticity ntawm daim tawv nqaij.
- Tiv thaiv lub cev hlwb los ntawm oxidation.
- Nyob rau qhov ceev ntawm tag nrho cov txheej txheem metabolic.
- Reacts nrog radionuclides thiab ceev lawv tshem tawm ntawm lub cev.
Thaum siv cov tshuaj ntxiv no, nws tsim nyog xav tias tshaj qhov nyiaj pub dawb txhua hnub yog qhov ua rau muaj qhov tshwm sim. Cov tsos mob ntawm kev noj tshuaj ntau dhau tuaj yeem tshwm sim, uas suav nrog tuag tes tuag taw, kiv taub hau, raws plab thiab ntuav. Qee zaum, kev siv cov reagent ntau dhau tuaj yeem ua rau tuag taus. Kev tuag tshwm sim nyob rau hauv cov xwm txheej uas koob tshuaj tartaric acid tshaj 7.5 grams ib 1 kilogram ntawm qhov hnyav.
Yuav kom tsis txhob ua mob rau koj lub cev, tsis txhob nce cov khoom noj txhua hnub ntawm koj tus kheejpom zoo. Qhov no tsuas yog ua tau los ntawm tus kws kho mob uas tuaj koom. Tshwj xeeb tshaj yog yog hais tias tus neeg mob yog predisposed rau herpes, muaj rhiab heev ntawm daim tawv nqaij, los yog impaired absorption ntawm tej acids.
Daim Ntawv Thov Khoom Noj
Tartaric acid, cov mis uas tau qhia saum toj no, tso cai rau koj ua kom cov txheej txheem lwj thiab lwj ntawm cov khoom. Vim cov cuab yeej no, lub compound tau dav siv hauv kev lag luam khoom noj. Tartaric acid tiv thaiv kev lwj ua ntej ntawm cov hmoov nplej thiab cov kaus poom. Feem ntau, cov compound yog siv los ua antioxidant reagent lossis acidity regulator.
Nyob rau hauv cov dej cawv, cov dej hauv lub rooj, cov khoom qab zib thiab khoom qab zib, nrog rau cov khoom noj kaus poom, muaj tartaric acid. Tau txais cov khoom xyaw no yog ib txoj kev yooj yim. Ua li no, siv cov khoom pov tseg uas tau tsim los ntawm kev tau txais cawv txiv hmab.
Nws yog ib qho tsim nyog sau cia tias lub substrate yog siv los khaws cov xim dawb thiab plasticity ntawm chocolate icing, txhim kho whipped proteins, thiab kuj kom loosen lub khob noom cookie. Tsis tas li ntawd, E334 additive ua rau nws ua tau kom soften lub saj ntawm cawv cawv, ua rau lawv ntau tart thiab qab ntxiag.
Kev siv tartaric acid hauv lwm qhov chaw
Tartaric acid tau dav siv tsis yog hauv kev lag luam khoom noj xwb, tab sis kuj tseem siv tshuaj. Rau kev kho mob lub hom phiaj, lub compound yog siv raws li ib tug pab tivthaiv. Nws yog siv nyob rau hauv kev tsim cov solubletshuaj, ib co laxatives, thiab effervescent ntsiav tshuaj.
Tartaric acid kuj tseem siv hauv cosmetology. Cov tshuaj no muaj nyob rau hauv ntau cov tshuaj zawv plaub hau, tshuaj pleev ib ce, cream thiab peels tsim rau cov plaub hau thiab kev tu tawv nqaij.
Qhov tseeb, tartaric acid yog siv rau ntau qhov chaw. Piv txwv li, lub compound yog siv nyob rau hauv lub textile kev lag luam los kho cov xim raws li ib tug tshwm sim ntawm dyeing fabrics. Hauv kev tsim kho, cov tshuaj ntxiv yog siv los ua ib qho reagent. Nws yog ntxiv rau gypsum thiab cement sib tov. Vim li no, cov huab hwm coj solidifies qeeb dua.
Rochelle ntsev yog siv rau hauv cov txheej txheem tsim cov khoos phis tawj, lub suab nrov thiab microphones vim nws cov khoom piezoelectric.
