Feem ntau siv preservatives muaj xws li:

 

Calcium Propionate - dav siv nyob rau hauv qhob cij thiab buns los inhibit pwm

Sodium Propionate hmoov- muaj txiaj ntsig zoo hauv cov poov xab -cov khoom noj khoom haus uas muaj roj

Potassium Sorbate - haum rau ncuav mog qab zib, txhaws, thiab siab -cov khoom qab zib

Sorbic acid- zoo tiv thaiv pwm thiab cov poov xab hauv cov kua qaub

 

Piv txwv:Lub khob cij ua cov ncuav ci ntxiv 0.3% calcium propionate rau lub khob noom cookie. Txee lub neej tau nce los ntawm 5 mus rau 14 hnub ntawm chav tsev kub yam tsis muaj pwm loj hlob.

 

 

3. Ua kom zoo pH qib

 

Tsawg pH ib puag ncig ua rau nws nyuaj rau pwm kom loj hlob.

 

·Kho cov qauv siv cov zaub mov- qib acids thaum tsim nyog

·Ua ke pH tswj nrog cov tshuaj tua kab mob kom muaj zog tiv thaiv kab mob

 

Ntau cov tshuaj tiv thaiv, xws li sorbates, ua tau zoo dua hauv cov kua qaub me ntsis.

 

4. Ua kom nruj nruj thaum ua haujlwm

 

Tom qab-kev kis kab mob yog qhov loj ntawm pwm.

 

Cov ntsiab lus tseem ceeb ntawm kev tswj hwm muaj xws li:

 

·Cua txias tunnels thiab conveyors

·Slicing thiab ntim khoom

·Cua zoo nyob rau hauv cov chaw tsim khoom

 

Kev tu tsis tu ncua, kev huv huv, thiab kev pom huab cua pab txo cov pwm kis kab mob.

 

5. Txhim kho qhov ntim thiab khaws cia

 

Ntim plays lub luag haujlwm tseem ceeb hauv kev tiv thaiv pwm.

 

·Siv cov khoom ntim nrog cov dej noo zoo

· Xav txog kev hloov pauv huab cua ntim (MAP) qhov twg siv tau

· Khaws cov khoom tiav hauv qhov chaw huv, qhuav

 

Txo cov pa oxygen tuaj yeem ua rau cov pwm tuaj yeem qeeb.

 

6. Xav txog daim ntawv huv huv thiab lwm yam khoom siv ntuj tsim
