Foodservice case labels thiab industrial specifications yuav tsum sib npaug.

Thawing kuj tsis tiav cov kauj ruam ua noj. Hauv ntau daim ntawv thov, zaub qhwv tuaj yeem ncaj qha los ntawm khov rau hauv cov txheej txheem kub, uas txwv kev tuav thiab tuaj yeem pab tiv thaiv kev ntxhib los mos. Yog hais tias ib tug formulation yuav tsum tau thawing, tswj lub sij hawm thiab kub thiab siv cov khoom thawed tam sim ntawd nyob rau hauv lub site cov zaub mov- phiaj xwm kev nyab xeeb. Tus neeg yuav khoom yuav tsum tsis txhob tig tus kws ua zaub mov noj - ua ntej - noj cov khoom xyaw rau hauv qhov txias npaj - rau - noj cov khoom xyaw vim nws tau blanched ua ntej khov.

Yuav Ua Li Cas Ua Frozen Cauliflower Tsis Ua Nws Mushy

Vim tias blanching thiab khov tau softened qee cov qauv ntawm tes, khov cauliflower feem ntau xav tau kev ua noj tsawg dua li ib qho tshiab. Txoj kev yog nyob ntawm lub tais kawg.

Cov dej khov saum npoo av thiab cov dej tso tawm kuj cuam tshuam rau kev ua haujlwm. Cais cov IQF xoob xoob ua ntej ua noj, zam kom tsis txhob muaj lub tais ci, thiab tsis txhob ntxiv dej ntau tshaj li qhov xav tau. Cov dej khov loj tuaj yeem qhia tau tias cov khoom tau thawed thiab refrozen ua ke los yog cov dej noo nkag mus rau hauv pob, txawm tias clumping los ntawm nws tus kheej tsis ua pov thawj tias cov zaub mov tsis zoo. Thaum qhov kub thiab txias keeb kwm tsis paub meej lossis pob khoom puas lawm, tus neeg yuav khoom lossis chav ua noj yuav tsum ua raws li nws qhov kev tsis lees paub thiab zaub mov- cov txheej txheem kev nyab xeeb es tsis yog sim txiav txim siab txog kev nyab xeeb ntawm qhov pom ib leeg.

Dab tsi B2B Cov neeg yuav khoom yuav tsum lees paub ua ntej pom zoo ib yam khoom

Rau B2B kev yuav khoom, "blanched" tsuas yog qhov pib ntawm qhov tshwj xeeb. Tus neeg yuav khoom yuav tsum txuas cov txheej txheem txheej txheem rau daim ntawv thov npaj. Lub khw muag khoom noj khoom haus-hauv- hnab zaub, khoom noj khoom haus sab zaub mov, cov khoom noj muaj kua zaub, thiab cov zaub xam lav npaj txias tsis muaj kev tswj hwm kev nyab xeeb zoo ib yam lossis lub hom phiaj kev ntxhib los mos.
