Cov piam thaj twg nyob hauv qab zib? Sucrose, Brix thiab Purity
Aug 05, 2019
Sucrose yog cov suab thaj tseem ceeb hauv cov kua qab zib maturethiab cov suab thaj zoo li crystalline cane qab zib. Cov kua txiv hmab txiv ntoo kuj tseem muaj cov piam thaj dawb thiab fructose, feem ntau ntawm qis dua. Ob qho monosaccharides no feem ntau yog pab pawg ua kom txo cov suab thaj hauv kev tsom xam cov pas nrig. Lawv txoj kev sib koom tsis yog ruaj khov: cultivar, maturity, teb tej yam kev mob, ncua sij hawm tom qab sau, microbial deterioration, kub, pH thiab kev ua keeb kwm tag nrho yuav hloov tau.
Cov lus teb ntawd xav tau ob yam tseem ceeb. Ua ntej, hais tias sucrose yog tsim los ntawm ib chav tsev piam thaj thiab ib chav fructose tsis tau txhais hais tias lub chaw soj nstuam yuav tsum tshaj tawm sucrose li cov piam thaj dawb ntxiv rau dawb fructose. Lawv yog cov analytes sib txawv. Qhov thib ob, kev nyeem ntawv refractometer xws li 18℃Bx tsis zoo ib yam li 18% sucrose. Brix kwv yees tag nrho cov soluble solids; cov khib nyiab no suav nrog cov suab thaj thiab yaj uas tsis yog - cov khoom qab zib.
Rau kev yuav, tsim lossis tshawb xyuas daim ntawv pov thawj ntawm kev txheeb xyuas, pib nrog cov khoom tsim thiab kev txiav txim siab. Cov kua txiv hmab txiv ntoo, cov kua txiv hmab txiv ntoo, cov qab zib nyoos thiab cov qab zib ua kom zoo nkauj tsis muaj cov ntsiab lus dej tib yam lossis muaj pes tsawg leeg. Nug rau Brix thaum soluble- cov khoom sib xyaw ua ke tseem ceeb, Pol thaum pom tseeb sucrose yog qhov tseem ceeb, thiab siv tau cov txheej txheem chromatographic thaum koj xav tau cov lej sucrose, qabzib thiab fructose.
Lus teb luv luv:Sugarcane muaj cov sucrose, nrog me me ntawm cov piam thaj dawb thiab fructose. Tsis muaj kev tiv thaiv universal hais tias txhua tus pas nrig lossis kua txiv yog "20% qab zib." Tus lej muaj txiaj ntsig yuav tsum txheeb xyuas tus qauv, daim ntawv tsim khoom, chav tsev, txoj kev tshuaj xyuas thiab hauv paus.
Sucrose yog Cov Qab Zib Tseem Ceeb, Tsis yog Qab Qab Zib nkaus xwb
Sucrose yog ib qho disaccharide: ib chav tsev piam thaj thiab ib chav fructose koom ua ke los ntawm kev sib cog lus tshuaj. Glucose thiab fructose yog monosaccharides. Hauv cov sucrose zoo lawm lawv tsis tuaj yeem yog ob lub suab thaj dawb, yog li cov khoom siv -qab zib yuav tsum sau sucrose cais los ntawm cov piam thaj dawb thiab dawb fructose. Qhov kev sib txawv no tseem ceeb thaum koj sib piv qhov qab zib, tus cwj pwm fermentation, inversion, crystallization kev ua tau zoo los yog cov khoom specification.
Hauv cov ntsiab lus cane, cov piam thaj thiab fructose feem ntau sib tham ua ke raws li kev txo cov suab thaj. Sucrose yog suav tias yog qhov tsis yog - txo cov suab thaj. Yog hais tias sucrose yog hydrolyzed, los yog inverted, nws daim ntawv cog lus yog phua thiab dawb qabzib thiab fructose yog tsim. USDA cov ntsiab lus qab zib yog li txhais cov piam thaj hloov pauv raws li kev sib xyaw ntawm cov piam thaj thiab fructose ua los ntawm hydrolysis ntawm sucrose. Kev txo qis nce ntxiv - qab zib tshwm sim tuaj yeem cuam tshuam rau qhov zoo, tab sis nws xav tau cov ntsiab lus; nws tsis tuaj yeem ua pov thawj ntawm ib qho laj thawj tshwj xeeb.
Lub cev muaj pes tsawg leeg ntawm stalk yog sib txawv. USDA Kev Tshawb Fawb Kev Tshawb Fawb Ua Haujlwm ua haujlwm ntawm yim lub suab thaj cultivars pom tias Brix thiab sucrose tau nce sai heev thaum lub sijhawm ripening thaum qabzib thiab fructose poob qis. Txoj kev tshawb no kuj pom qhov sib txawv ntawm cov cultivars thiab nruab nrab ntawm cov nroj tsuag -cane thiab ratoon qoob loo. Tias yog vim li cas cov qoob loo- dav feem pua coj los ntawm ib lub vev xaib dav dav yog qhov tsis zoo rau cov ntaub ntawv sawv cev ntau.
| Lub sij hawm | Nws txhais li cas ntawm no | Kev ceev faj txog kev yuav khoom |
|---|---|---|
| Sucrose | Cov qab zib tshaj plaws hauv cov kua txiv hmab txiv ntoo loj; ib qho tsis- txo cov disaccharide | Tsis txhob sib npaug nws cov piam thaj thiab fructose units nrog cov piam thaj dawb thiab fructose |
| Glucose | Ib qho dawb txo monosaccharide tam sim no hauv cov kua txiv hmab txiv ntoo | Concentration hloov nrog qoob loo thiab keeb kwm ntawm cov khoom; xav tau ib txoj hauv kev thiab hauv paus |

| Txo cov suab thaj | Ib pab pawg ua haujlwm uas feem ntau ntes cov piam thaj dawb thiab fructose hauv kev txheeb xyuas cane | Txheeb xyuas cov txheej txheem hais, kev qhia thiab seb qhov tshwm sim puas tau tshaj tawm raws li cov piam thaj hloov pauv |
Rau cov neeg yuav khoom, "muaj sucrose, qabzib thiab fructose" yog cov lus teb muaj pes tsawg leeg, tsis yog cov lus qhia tiav. Koj daim ntawv tseem xav tau qhov tseem ceeb, kam rau ua, txoj kev, qauv hauv paus thiab ntau lub ntsiab lus. Yog hais tias cov khoom npaj yog ntim cane es tsis yog cov kua txiv hmab txiv ntoo, covXMSD tev nplooj nplooj qab zib tshiabpab txhais lub cev daim ntawv; nws tsis hloov analytical qab zib cov ntaub ntawv rau ib tug ntau yam.
Yog vim li cas qab zib tau hloov nrog lub Cane thiab cov qauv
Cov txiaj ntsig cane belongs rau ib qho piv txwv. Ntau yam thiab maturity cuam tshuam rau sucrose tsub zuj zuj. Huab cua, dej, av thiab qoob loo tej yam kev mob tuaj yeem cuam tshuam kev loj hlob thiab kua txiv hmab txiv ntoo. Ib feem ntawm cov stalk sampled thiab txoj kev stalks tau ua ke tuaj yeem hloov qhov chaw kuaj. Ib qho piv txwv saum toj kawg nkaus -section grab tsis sib npaug rau cov neeg sawv cev sib xyaw los ntawm kev lag luam ntau.
Lub sijhawm tom qab sau qoob loo tseem ceeb thiab. Txiav cane tseem yog cov khoom siv roj ntsha, thiab sov, puas los yog ua haujlwm tsis zoo stalks tuaj yeem deteriorate. Cov kab mob thiab cov tshuaj endogenous tuaj yeem haus lossis hloov cov suab thaj. Sucrose inversion tuaj yeem ua rau cov piam thaj dawb thiab fructose, thaum lwm yam kev hloov pauv tuaj yeem txo qis tag nrho cov txiaj ntsig qab zib. Qhov tshwm sim los ntawm lub suab cane kuaj tam sim ntawd yuav tsum tsis txhob xav tias sawv cev rau lub pas dej nyob hauv lub sijhawm sib txawv-kub keeb kwm.
Kev npaj hauv chav kuaj yog lwm qhov kev hloov pauv. Tag nrho - feem pua stalk, qhia cov kua txiv hmab txiv ntoo thiab lim - cov kua txiv hmab txiv ntoo siv cov lej sib txawv. Wet-paj g/100 g, qhuav-pab g/100 g thiab g/L tsis tuaj yeem muab piv nrog yam tsis muaj cov ntaub ntawv ceev thiab noo noo. Txawm hais tias cov lus "kua txiv qab zib" tsis tiav tshwj tsis yog txoj kev hais tias nws ntsuas ib qho molecule, tag nrho cov suab thaj uas txheeb xyuas, txo cov suab thaj lossis cov khoom sib tov.
Piv txwv li: tib lub npe qoob loo, sib txawv kom loj hlob.Ob qhov ntau tuaj yeem raug muag raws li cov suab thaj thaum ib tus muaj sucrose siab dua thiab qis dua hexoses dawb dua li lwm qhov. Kev tshaj tawm dav dav xws li "20% qab zib" yuav zais qhov txawv. Rau kev yuav cov kua txiv hmab txiv ntoo, peb yuav thov tus neeg sawv cev Brix thiab Pol cov txiaj ntsig ntawm qhov tau txais thiab cov khoom siv -qab zib chromatography thaum pub dawb-qab zib cais cuam tshuam rau daim ntawv thov.
Khaws qhov muag pom kev zoo thiab tshuaj zoo sib cais. Ncaj stalks, huv si txiav xaus, nqaij daj ntseg thiab cov khoom nqus tsev tsis zoo pab ntsuam xyuas cov pob - ntau ntau, tab sis lawv tsis tuaj yeem suav cov sucrose. Qab zib saj kuj yog ib qho kev ntsuam xyuas tsis txaus ntseeg vim tias qhov kub thiab txias, acids, aroma, kev nkag siab ntawm tus kheej thiab kev sib xyaw ntawm cov suab thaj cuam tshuam rau kev hnov qab qab zib. Lub vaj huam sib luag tasting tuaj yeem pom zoo tsw; tsuas yog ib qho kev ntsuam xyuas tsim nyog tuaj yeem pom zoo muaj pes tsawg leeg.
Cane Juice, Cane Syrup, Raw Qab Zib thiab Dawb Qab Zib yog cov ntawv sib txawv
Ib tug stalk, qhia cov kua txiv hmab txiv ntoo, concentrated syrup thiab siv lead ua yog cov ntaub ntawv muaj feem xyuam, tab sis lawv cov compositions tsis hloov pauv. Kev tshem tawm dej concentrates soluble solids. Kev qhia meej hloov cov khoom raug tshem tawm thiab yaj. Inversion tuaj yeem hloov qhov sib npaug ntawm sucrose thiab dawb qabzib ntxiv rau fructose. Crystallization cais cov sucrose- cov khoom nplua nuj los ntawm niam cawv. Cov kev sib txawv ntawm daim ntawv no txaus los txhais cov lus qhia; qhov ua tiav extraction sequence belongs rau hauv ib tug tshwj xeeb kev pab cuam.
| Yam khoom | Lo lus qhia rau koj | Dab tsi tseem xav tau kev lees paub |
|---|---|---|
| Cane kua txiv | Ib qho dej sib tov qhia los ntawm cane, nrog sucrose tseem ceeb ntawm nws cov suab thaj | Brix, cov khoom qab zib, lub sij hawm-kub keeb kwm, dilution, huv si thiab analytical hauv paus |
| Cane syrup | Concentrated cane kua txiv nyob rau hauv cov khoom txhais lus | Cov khoom, sucrose, txo cov suab thaj, inversion, cov khoom xyaw, ceev thiab kev ua lag luam- tus kheej tshwj xeeb |
| Raw cane qab zib | Nyob rau hauv Codex, ib nrab purified sucrose crystals los ntawm ib nrab purified cane kua txiv, them nrog ib zaj duab xis ntawm cane molasses | Polarization, noo noo, xim, tshauv, qib thiab lo lus uas peb xav tau |
| Dawb qab zib | Codex txhais nws li purified crystallized sucrose nrog polarization ntawm tsawg kawg yog 99.7℃Z | Daim ntawv cog lus qib, xim, noo noo, granulation, kab mob, ntim thiab siv tus qauv |
Xim tsis yog ib qho kev sim molecular. Cov khoom xim av tuaj yeem khaws cia lossis suav nrog ib feem ntawm molasses, tab sis qhov ntxoov ntxoo ib leeg tsis tuaj yeem qhia koj txog nws cov sucrose, qabzib lossis fructose concentration. Codex distinguishes dawb, cog los yog zeb dawb, mos dawb, mos xim av thiab nyoos cane qab zib los ntawm kev txhais thiab muaj pes tsawg leeg los yog polarization cov txheej txheem. "Natural," "raws", "xim av" thiab "unrefined" yuav tsum tsis txhob siv raws li lawv yog ib qib analytical.
Syrup kuj xav tau ib tus neeg paub meej. USDA tus qauv US qib rau refiners 'sirup hais tias cov khoom yuav yog ib feem los yog tag nrho inverted thiab ntsuam xyuas Brix ntxiv rau ib feem ntawm tag nrho cov suab thaj -sucrose ntxiv rau txo cov suab thaj- rau Brix solids. Qhov piv txwv ntawd qhia tau tias yog vim li cas lub syrup tsis tuaj yeem ua tus cwj pwm los ntawm Brix ib leeg. Nws tsis tsim ib tug universal specification rau txhua cane syrup los yog txhua qhov chaw ua lag luam.
Yog tias koj qhov kev txiav txim siab cuam tshuam txog kev haus dej haus, kev noj qab haus huv los yog ua tiav - haus dej haus tsis yog cov piam thaj, siv qhov sib caisqab zib kua txiv kab mob kev noj qab haus huv thiab B2B siv cov peev txheej. Txoj haujlwm tsom xam ntawm no yog nqaim dua: npe cov suab thaj kom raug, siv qhov kev ntsuas kom raug thiab khaws tus nqi txuas nrog rau daim ntawv khoom.
Brix Measures Soluble Solids, Tsis yog Sucrose Ib leeg
Degrees Brix yog raws li qhov loj ntawm sucrose nyob rau hauv ib tug ntshiab sucrose -dej siv tshuaj. Hauv cov kua txiv hmab txiv ntoo tiag, lub refractometer teb rau tag nrho cov khoom yaj. Sucrose tuaj yeem ua tus tswj hwm, tab sis cov piam thaj, fructose, organic acids, minerals thiab lwm cov khoom siv soluble kuj pab. Cov kev nyeem tau siv tau yog li cov khoom sib tov uas tau hais tawm ntawm sucrose- qhov sib npaug, tsis yog kev xaiv sucrose.
Qhov no yog vim li cas 18℃Bx kua txiv tsis tau txais 18 g sucrose ib 100 g. Kev nyeem ntawv tseem tuaj yeem pab tau zoo heev rau kev txais kev tswj hwm, kev xav, kev txheeb xyuas kev sib tw thiab kev sib piv ntau thaum ntsuas ntsuas ntsuas, ntsuas qhov ntsuas kub, ntsuas ntsuas thiab ntsuas ntsuas. Nws tsuas teb ib lo lus nug txawv ntawm chromatography.
Qhia meej seb Brix yuav ntsuas li cas. Cov ntaub ntawv ntsuas hom, calibration standard, kho qhov kub thiab txias los yog siv qhov ntsuas kub, cov qauv pom los yog kev qhia meej, tus naj npawb ntawm kev nyeem ntawv, kev lees paub kam rau ua thiab qauv qauv. Yog tias tus neeg muag khoom thiab tus neeg yuav khoom siv cov kev npaj sib txawv lossis cov rooj sib tham kub, ob lub chaw soj nstuam muaj peev xwm tsim tau cov lej uas nyuaj rau kev sib piv.
Piv txwv li: sib npaug Brix, tsis sib xws.Juice A thiab Juice B ob leeg nyeem 18.0℃Bx. Yog tias Juice A muaj 16.2 Pol thiab Juice B muaj 14.4 Pol, lawv pom meej purities yog 90.0% thiab 80.0% raws li. Sib npaug soluble solids tsis txhais hais tias sib npaug pom meej sucrose. Tus neeg yuav khoom uas tau pom zoo ob qho tib si nkaus xwb vim "Brix yog 18" yuav plam qhov sib txawv ntawm kev lag luam.
Tsis txhob rho Pol los ntawm Brix thiab hu cov qabzib ntxiv rau fructose. Brix suav nrog soluble non- qab zib, thaum Pol yog qhov kev kwv yees kho qhov muag cuam tshuam los ntawm cov qauv matrix. Qhov sib txawv no muaj cov teebmeem tshuaj ntsuam xyuas thiab yaj uas tsis yog- cov khoom qab zib thiab txo cov suab thaj. Kev ntsuam xyuas cov khoom sib cais yog xav tau thaum qhov sib cais tseem ceeb.
Pol thiab pom meej Purity teb cov lus nug sib txawv
Pol yog pom meej sucrose ntsuas los ntawm optical rotation nyob rau hauv ib tug txhais txoj kev. Sucrose tig lub teeb polarized, yog li polarization yog qhov tseem ceeb hauv kev lag luam qab zib thiab tswj cov txheej txheem. Lo luspom meejQhov teeb meem vim tias qabzib, fructose thiab lwm yam khoom siv kho qhov muag tuaj yeem cuam tshuam rau kev nyeem ntawv. Pol tsis zoo ib yam rau ib qho kev xaiv chromatographic sucrose tus nqi.
Pom meej purity yog feem ntau xam raws li Pol faib los ntawm Brix, muab faib los ntawm 100. Nws kwv yees qhov feem ntawm cov ntsuas soluble solids sawv cev los ntawm pom meej sucrose. LSU AgCenter txheeb xyuas Brix, Pol thiab purity raws li cov txheej txheem tswj kev sib txawv hauv kev ua haujlwm qab zib: cov khib nyiab, pom tseeb sucrose thiab qhov piv ntawm sucrose rau cov khib nyiab. Kev ceeb toom tag nrho peb txwv tsis pub ua yuam kev ntawm kev nthuav qhia ib tus lej hauv peb lub npe.
Ua piv txwv ua haujlwm: los ntawm Brix thiab pom meej purity rau kwv yees Pol.
Ib tug hypothetical 1,000 kg kua txiv ntau ntsuas 18.0℃Bx thiab muaj 85.0% pom meej purity.
Soluble solids=1,000 kg × 18.0% =180 kg.
Kwv yees Pol hauv kua txiv=18.0 × 0.850 =15.3.
Pom meej sucrose sib npaug hauv qhov ntau=1,000 kg × 15.3% =153kg ua.
Qhov seem 27 kg ntawm soluble solids yogtsis cia li txo qab zib. Nws tuaj yeem suav nrog piam thaj, fructose, acids, minerals thiab lwm yam khoom siv soluble, ntxiv rau cov kev txwv ntawm kev ntsuas pom tseeb. Siv cov khoom xyaw tsim nyog- qab zib txoj kev ua ntej muab qhov loj ntawd.
Qhov kev suav no yog qhov loj - qhov kwv yees qhov sib npaug rau ntau qhov kev xav, tsis yog kev cog lus rov qab los. Nws tsis kwv yees ntau npaum li cas crystalline qab zib ib lub chaw yuav rho tawm, vim hais tias extraction efficiency, clarification, inversion, cov txheej txheem poob thiab cov khoom yuav tsum tau zaum kawg yog cais cov teeb meem. Ua kom qhov kev suav bounded tiv thaiv kev yuav khoom kwv yees los ntawm kev xa mus rau qhov tsis muaj kev txhawb nqa ntau lawm.
Rau qhov kev pab cuam tau txais, txiav txim siab seb Pol thiab pom meej purity puas txaus rau kev tswj niaj hnub. Tej zaum lawv yuav yog cov cuab yeej tshuaj ntsuam xyuas zoo thaum tus neeg muag khoom keeb kwm thiab daim ntawv thov ruaj khov. Yog tias formulation, fermentation, crystallization tus cwj pwm, qhov tseeb los yog txee ruaj khov nyob ntawm tus kheej molecules, ntxiv sucrose ncaj qha, qabzib thiab fructose tshwm sim es tsis txhob nug Pol los teb cov lus nug nws tsis yog tsim los teb.

Txheeb xyuas tus tuav, qhov chaw, thaj tsam, tus qauv, tshaj tawm lub cev thiab hnub siv tau siv cov ntawv luam. XMSDdaim ntawv pov thawj saib xyuasyog lub ntsiab lus pib rau kev sib tham txog cov ntaub ntawv, tsis yog hloov pauv rau kev txiav txim - kev pom zoo tshwj xeeb.
Ntawm qhov kev tshuaj xyuas zaum kawg, nug ib lo lus nug yooj yim: lwm tus neeg tsim nyog tuaj yeem rov ua dua qhov kev txiav txim siab los ntawm kev yuav khoom, cov ntaub ntawv ntau, qauv thiab daim ntawv pov thawj? Yog tias cov lus teb nyob ntawm "cov ntsiab lus qab zib," "siab sucrose" lossis "18 Brix" yam tsis muaj qauv thiab hauv paus, cov ntaub ntawv tsis tiav. Cov ntsiab lus meej tiv thaiv kev sib cav tom qab pib tsim khoom.
Xa daim foos ua ntej tus lej.Qhia koj cov khoom lag luam qab zib uas xav tau, hom phiaj, daim ntawv thov, ntau qhov loj, Brix lossis cov khoom siv -cov piam thaj txwv, txoj hauv kev thiab ntim khoom xav tau los ntawmXMSD contact page. Peb tuaj yeem tshuaj xyuas seb qhov kev thov tshwj xeeb thiab cov ntaub ntawv txhawb nqa puas meej txaus rau kev lees paub tus neeg muag khoom.
Teb kawg
Cov piam thaj tseem ceeb hauv qab zib yog sucrose. Cov piam thaj dawb thiab fructose kuj tseem muaj thiab feem ntau tham txog kev txo cov suab thaj. Lawv cov concentration sib txawv nrog tus pas nrig thiab nws cov keeb kwm, yog li tsis muaj ib qho tag nrho - feem pua ntawm cov qoob loo yuav tsum raug kho raws li universal.
Rau kev txiav txim siab ua lag luam, khaws plaub lub tswv yim sib cais: Brix kwv yees cov khoom tawg yooj yim; Pol kwv yees pom meej sucrose; pom meej purity yog Pol faib los ntawm Brix; Direct chromatography tuaj yeem suav cov sucrose, qabzib thiab fructose tus kheej. Txuas txhua tus nqi rau ib daim ntawv teev khoom, qauv, qauv, chav tsev thiab hauv paus. Qhov ntawd muab cov lus teb rau koj uas tuaj yeem muaj sia nyob ntawm kev tsim, tau txais kev tshuaj xyuas thiab kev tshuaj xyuas tus neeg muag khoom.
