I'm Jacky los ntawm GreenLand- zaub mov. Thaum cov neeg yuav khoom qhia rau kuv tias "cov khoom lag luam tsis zoo," feem ntau kuv nres -vim "mushy" tsis yog ib qho teeb meem. Nws yog qhov kawg cov tsos mob ntawm ib tug saw:

1. freezing ceev (ice crystal loj)

2. cov ntaub so ntswg puas (cell phab ntsa tawg)

3. poob dej tom qab thawing (dej tso tawm)

4. ua noj ua haus (mos, dej tom)

Thiab qhov phem tshaj plaws? Ib qho qauv tuaj yeem saib zoo hauv lub hnab tab sis ua tsis tiav hauv lub lauj kaub. Tias yog vim li cas koj thiaj li tsim nyog tau txais cov lus piav qhia meej uas koj tuaj yeem siv hauv kev yuav khoom thiab QC.

Hauv tsab xov xwm no, kuv yuav qhia koj -ib kauj ruam ntawm kauj ruam -yuav ua li cas khov ceev hloov zaub zoo nkauj, qhov no txhais li cas hauv IQF ntau lawm, thiab dab tsi cov neeg yuav khoom yuav tsum tau hais kom tiv thaiv kev sib xws.

 

 

 

 

Txoj cai yooj yim: khov ceev tswj cov dej khov siv lead ua loj

Cov zaub feem ntau yog dej tuav hauv ib qho kev cog qoob loo. Thaum peb khov lawv, cov dej ntawd hloov mus ua cov dej khov nab kuab. Covceev ntawm khov txiav txim qhov loj thiab qhov chaw ntawm cov muaju, thiab qhov ntawd, nyob rau hauv lem, txiav txim qhov kev ntxhib los mos.

Kev tshuaj xyuas kev tshawb fawb tsis ntev los no ntawm cov dej khov morphology hauv cov khoom noj qhia txog qhov tseem ceeb ntawm kev sib raug zoo:

Txias qeeb → cov dej khov loj loj(feem ntau ua rau puas tsuaj)

Kev khov sai sai → siv lead ua me me(feem ntau zoo dua)

Lwm qhov kev tshuaj xyuas qhia txog qhov ntawdcov dej khov uas tsis xav tautuaj yeem hloov cov khoom noj cov qauv, ua rau kev ntxhib los mos thiab lwm yam tsis zoo.

Tus neeg yuav khoom txhais lus:
Yog tias cov txheej txheem khov qeeb, koj yuav tsum tau yuav "ice crystal puas tsuaj" ntim li zaub.

 

 

 

Yuav ua li cas nyob rau hauv cov zaub (vim li cas qeeb freezing ua tej yam mushy)

 

1) Kev qeeb qeeb ua rau muaj cov muaju loj thiab cov ntaub so ntswg ntau dua

Thaum khov qeeb, dej muaj sij hawm tsiv mus nyob, cia cov dej khov ua kom loj tuaj. Cov crystals loj no tuaj yeem cuam tshuam cov phab ntsa ntawm tes thiab daim nyias nyias -tshwj xeeb tshaj yog nyob rau hauv cov ntaub so ntswg - ua rau cov txheej txheem tawg.

Kev tshuaj xyuas ntawm cov dej khov morphology piav qhia tias kev khov qeeb qeeb yog txuas nrog cov pob zeb loj dua thiab qhov ua tau zoo tsis zoo, thaum lub sijhawm khov sai ua rau cov pob zeb me me thiab txhim kho cov txiaj ntsig zoo.

 

2) Cov hlwb puas txhais tau tias poob poob tom qab thawing

Thaum cov cell membranes rupture, cov dej tsis nyob rau hauv cov qauv. Tom qab thawing (lossis txawm tias thaum ua noj), cov dej ntawd khiav tawmpoob, thiab qhov seem yog softer, tsawg elastic ntaub so ntswg.

Ib qho kev txheeb xyuas cais ntawm kev tswj cov dej khov hauv cov khoom noj khov sau tseg tias cov dej khov nab kuab tuaj yeem ua rau muaj kev hloov pauv tsis tau hauv cov qauv zaub mov thiab ua rau muaj kev puas tsuaj.

 

3) Tom qab ntawd kev ua noj ua kom pom qhov tsis xws luag

Thaum tshav kub kub ntxiv cov ntaub so ntswg uas twb puas lawm. Qhov no yog vim li cas cov zaub yuav zoo li siv tau thaum khov tab sis ua dej thiab muag thaum nws siav.

 

Jacky's Experience:
Cov neeg yuav khoom feem ntau liam "blanching" ua ntej. Txawm li cas los xij, thaum cov txheej txheem blanching ruaj khov,freezing ceev thiab txias - chain stabilityfeem ntau yog cov hloov pauv zais tom qab qhov tsis sib haum xeeb tom qab.

 

 

 

 

Cov "zoo killer" feem ntau buyers tsis nco qab: Recrystallization

Txawm hais tias cov txheej txheem khov yog nrawm thiab zoo meej rau Hnub 1, kev ntxhib los mos tseem tuaj yeem degrade tom qab vimrecrystallization-txoj kev uas cov dej khov ua kom rov ua dua thiab loj dua thaum lub sijhawm kub hloov pauv.

Kev tshuaj xyuas ntawm cov dej khov morphology qhia txog qhov ntawdkub hloov pauv thaum khaws ciatxhawb recrystallization, uas yog ncaj qha mus rau qhov zoo deterioration.

Tus neeg txhais lus:
Kev khov ceev ceev tsis tuaj yeem cawm koj yog tias koj cov saw hlau txias tsis ruaj khov. IQF zoo yog tiv thaiv los ntawm kev sib xyaw ua ke ntawmfreezing ceev + ruaj khov cia kub.

 

 

 

 

Vim li cas qee cov zaub "cia li khov" zoo dua li lwm tus

 

1) Cov ntaub so ntswg sib txawv

Cov nplooj ntsuab muaj cov ntaub nyias nyias thiab thaj chaw loj, ua rau lawv yooj yim rau kev puas tsuaj thiab feem ntau yuav plam kev ntxhib los mos. Hauv paus zaub feem ntau muaj cov qauv denser thiab tuaj yeem zam ntau dua hauv qee qhov kev siv.

 

2) Txiav me me hloov khov ceev

Cov me me khov sai dua (tag nrho lwm yam sib npaug). Ib tug diced carrot freezes ntau uniformly tshaj ib tug tuab chunk. Tias yog vim li cas txiav- tswj qhov loj me tsis yog hais txog qhov tsos- nws yog hais txogkhov physics.

 

3) Cov ntsiab lus dej thiab cov phab ntsa ntawm tes muaj teeb meem

Cov zaub uas muaj cov dej siab ntau dua rau kev puas tsuaj los ntawm kev tsim dej khov. Qhov no yog ib qho laj thawj vim li cas qee cov khoom lag luam xav tau kev tswj xyuas nruj dua.

Kev tshuaj xyuas ntawm cov txiv hmab txiv ntoo khov thiab zaub zoo qhia tau hais tias ntau yam kev ua haujlwm thoob plaws hauv cov saw hlau cuam tshuam rau qhov zoo kawg nkaus; thaum khov yog qhov nruab nrab, nws tsis yog qhov tseem ceeb xwb.

 

 

 

 

 

Dab tsi "ceev khov" zoo li hauv cov chaw tsim khoom tiag tiag (thiab vim li cas IQF feem ntau yeej)

 

IQF systems (fluidized txaj, siv, kauv) yog tsim tshwj xeeb los tsav cov cua kub hloov ceev.

FAO phau ntawv qhia khov kho piav qhiafluidized txaj khov: Cov cua txias ntws los ntawm lub txaj perforated kom cov khoom raug tshem tawm hauv huab cua thiab khov ib leeg. Qhov no txhawb cov txheej txheem IQF thiab pab tiv thaiv lumping.

 

Tus neeg yuav khoom:
Thaum tus neeg muag khoom hais tias "IQF," koj yuav tsum nug dab tsihom lub freezerlawv siv thiab tswj lawv li castso zis tej yam kev mob. Cov qauv sib txawv ua rau sib txawv khov kinetics thiab uniformity.

 

 

 

 

 

Tus neeg yuav khoom daim ntawv txheeb xyuas: Yuav ua li cas qhia kom meej qhov kev ntxhib los mos

Koj tsis tas yuav sau ib daim ntawv pov thawj hauv koj Daim Ntawv Txiav Txim Siab (PO). Koj tsuas yog xav tau ob peb yam khoom muaj zog, siv tau.

 

1) Nug kom khov cov pov thawj tswj, tsis yog "IQF" xwb

Lub Freezer hom (Fluidized txaj / Belt / Kauv).

Core kub lub hom phiaj ntawm kev tso tawm.

Kev ntsuas coj los txo cov clumping thiab tsis sib xws.

 

2) Xauv hauv kev txiav me me kam rau ua

Txiav me me cuam tshuam rau kev khov nrawm thiab sib xws. Yog hais tias txiav loj drifts, qhov kev ntxhib los mos yuav drift.

 

3) Yuav tsum muaj kev qhuab qhia txias txias

Qhov no yog qhov tseem ceeb vim tias recrystallization yog tsav los ntawm qhov kub thiab txias.

 

 

4) Txhais qhov kev xeem ua noj ua haus (cov lus yuav khoom, tsis yog lus lab)

Piv txwv:

●"Tom qab steaming rau X feeb, tej daim yuav tsum nyob twj ywm thiab tsis mushy."

● "Drip poob tom qab thaw / ua noj yuav tsum nyob rau hauv kev pom zoo txwv."

Qhov no yog li cas cov neeg yuav khoom txhais cov physics khov rau hauv kev lees txais kev lag luam.

 

 

 

Feem ntau buyer misconceptions (uas ua rau kev txiav txim tsis zoo)

 

Misconception 1 - "Yog tias nws khov, kev ntxhib los mos raug kaw mus ib txhis"

Kev muaj tiag:Freezing slows cov tshuaj tiv thaiv, tab siskub hloov pauvtseem tuaj yeem ua rau kev ntxhib los mos los ntawm recrystallization.

 

Misconception 2 - "IQF cia li txhais tau tias zoo"

Kev muaj tiag:IQF yog lub hom phiaj tsim. Kev ua tiav tiag tiag yog nyob ntawm qhov sib npaug ntawm qhov sib npaug, kev tswj cov dej noo ntawm qhov chaw, thiab cov saw hlau txias ruaj khov.

 

Misconception 3 - "Soft texture txhais tau tias tus neeg muag khoom siv cov khoom qub"

Kev muaj tiag:Qee zaum yog, tab sis ntau zaus lub hauv paus yogkhov ceevlos yogkub ua phemtom qab khov.
