Cold chain & FAQ:What is the “Cold Chain”?

What is Frozen Food?A Food -hich has #een su#ected to a reezing "rocess

What is Quick Frozen Food?Food selected in "ea/ condition and reshness then

-here "roducts are transerred rom one cold area toanother

– *=am"les on the transer "oints– Blast reezer to Factor) cold store.– Factor) cold store to truc/.– !ruc/ to 'istri#utor cold store (e.g.: incoming receiving at Al-

– 'istri#utor cold store to >utlets ( e.g.: Products loading from

Al- Yasra to POS)



– Freuent or #rolonged door o#ening in 1ehicles during distri#ution and deli%er) is a maor cause otem"erature a#use.

– Freuent or "rolonged recei1ing or #re#aring o the"roducts in the W.H "re"aring area 3marshalling area4 isalso a cause o tem". a#use.





• 0re1entati1e Actions:– Food com"anies must realize that

trans!er #oints are "otentialtem"erature a#use areas or their"roducts.

– !he num#er o transer "oints or a gi%en"roduct should #e identifed and current"ractices e%aluated.
