Kev Siv Ntshav Noj hauv Tsiaj Pub

Kev siv cov ntshav pluas noj hauv tsiaj pub
Ib qho kev sim tau ua los ntawm cov nyhuv puffed ntshav noj rau cov dev loj hlob. Nws tau pom tias ntxiv 5% mus rau 10% ntawm puffed ntshav pluas noj rau pub tuaj yeem hloov qee feem ntawm cov ntses pluas noj kom ua tiav cov txiaj ntsig zoo noj. Cov dev kuaj tau loj hlob zoo thiab txhua pab pawg tau nce qhov hnyav. Kev noj zaub mov noj thiab lwm yam zoo dua li cov pab pawg tswj hwm, thiab pub nws tus kheej muaj qhov zoo ntawm kev ua haujlwm yooj yim, kev tu cev, kev pub mis yooj yim, thiab txuag kev ua haujlwm. Tshwj xeeb tshaj yog thaum ntxiv cov ntshav ntxiv yog 5%, qhov zoo tshaj plaws pub noj tuaj yeem ua tiav, uas tuaj yeem txhawb kev loj hlob ntawm cov tsiaj, txhim kho cov khoom noj rov qab, thiab muaj txiaj ntsig kev lag luam.

Ib txoj kev tshawb fawb tau ua los ntawm cov nyhuv ntawm hemoglobin hmoov npaj los ntawm cov tshuaj tsuag kom qhuav ntawm cov khoom noj dev thiab miv. Cov txiaj ntsig tau pom tias ntxiv 6% hemoglobulin hmoov rau cov khoom noj muaj txiaj ntsig zoo rau kev nce qhov hnyav ntawm cov dev thiab miv, thiab txhim kho cov khoom noj dev thiab miv. pom meej digestibility ntawm crude protein. Txawm li cas los xij, nws cov palatability tau qis dua li ntawm pawg tswj hwm. Qhov laj thawj tseem ceeb yog tias cov ntshav pluas noj muaj cov ntxhiab tsw ntawm cov ntshav thiab tsis muaj palatability.
Tej yam uas yuav tsum tau nco ntsoov thaum ntxiv ntshav mov rau tsiaj pub
Cov ntsiab lus ntawm cov amino acid tsis sib npaug

Txawm hais tias cov protein cov ntsiab lus ntawm cov ntshav noj yog siab, cov amino acid muaj pes tsawg leeg yog unbalanced. Thawj qhov txwv amino acid ntawm cov ntshav pluas noj yog isoleucine, thiab qhov thib ob txwv amino acid yog methionine. Yog li ntawd, nyob rau hauv cov tsiaj noj zaub mov uas muaj ntshav mov, cov ntsiab lus amino acid yuav tsum tau hloov kho kom nce Protein siv thiab pub mis.

Palatability tsis zoo

Palatability yog qhov kev xav ntawm qhov tsw, qhov tsos, kev ntxhib los mos thiab hardness ntawm pub, thiab yog cov lus teb ntawm tus tsiaj lub zeem muag, tsis hnov ​​tsw, saj thiab kov. Thaum lub sij hawm ua cov zaub mov qhuav qhuav, cov ntshav tau yooj yim deteriorated los yog kab mob, thiab cov qe ntshav poob dej thiab tawv thaum lub sij hawm ua. Cov ntshav tau noj mov feem ntau hnov ​​​​cov ntshav thiab muaj palatability tsis zoo. Kev txhim kho lub palatability ntawm cov ntshav pluas noj yog tsuas yog los ntawm kev txhim kho cov ntshav pluas noj technology. Cov txheej txheem sib txawv muaj qhov sib txawv hauv nws cov khoom noj khoom haus, palatability thiab digestibility. Yog li ntawd, thaum khaws cov as-ham ntawm cov ntshav pluas noj, tshem tawm nws cov ntshav tsis hnov ​​​​tsw los txhim kho nws cov palatability yog qhov tseem ceeb ntawm seb cov ntshav pluas tuaj yeem dhau los ua cov khoom noj muaj txiaj ntsig zoo rau tsiaj cov khoom noj rau dev thiab miv.

Ntshav zaub mov cia

Ntshav pluas mov yog yooj yim kis los ntawm cov kab mob thiab tsis yooj yim khaws cia rau lub sijhawm ntev. Nws yooj yim rau ya raws, clumping, pwm, thiab kev noj nyiaj txiag. Yog tias cov kua qaub uas tsim nyog (0.5% mus rau 1.5%) ntxiv thaum lub sij hawm tsim cov ntshav noj, nws tuaj yeem khaws cia rau ntau tshaj ib xyoos. Ntshav pluas noj yam tsis tau ntxiv txiv qaub tsuas yog khaws cia rau 4 lub lis piam. Yog tias cov ntshav qab zib yuav tsum tau khaws cia rau lub sijhawm ntev, cov kev ntsuas hauv qab no yuav tsum tau ua: ua kom sov cov ntshav pluas noj rau 100 degree, khaws cia rau 30 feeb, txias, thiab muab tso rau hauv lub thawv kaw lossis kaw rau hauv hnab yas. hnab rau khaws cia. Cov ntshav qhuav tuaj yeem ua kom tsis muaj menyuam nrog methyl bromide lossis lwm yam fumigants, lossis fumigated nrog vinyl chloride. Cov zaub mov fumigated ntshav tuaj yeem khaws cia rau hauv lub thawv kaw.
