Test your knowledge with these top questions!
Rapid freezing protects food texture mainly by limiting the size of what?
Large ice crystals can rupture cells, so smaller crystals help food keep its texture after thawing.
Why do cold-chain shipping boxes often have foam walls?
Foam traps gas in tiny cells, slowing the flow of heat through the box walls.
In cold-chain stock rotation, what does FEFO stand for?
A shipment received today may leave before older stock if its expiry date comes sooner.
Which change helps a frozen ice pack absorb heat inside a cold-chain shipping box?
Ice takes in heat as it melts while staying near 0°C, helping a package remain cold after the pack starts to thaw.
In the bullwhip effect, what does a small rise in store sales often cause?
Retailers over-order to play safe, wholesalers add more, so the factory sees a demand surge.
Which approach reduces the bullwhip effect in supply chains?
When suppliers see real checkout sales, they plan production instead of reacting to padded orders.
In package delivery, what does the term last mile describe?
This short leg uses many stops over small areas, so it often costs over half of total shipping.
Why do delivery couriers photograph packages at the door?
Photos plus GPS stamps settle disputes when customers report missing parcels or theft.
What device tracks temperature inside cold-chain shipments?
Loggers record readings every few minutes, so receivers can spot a warming spike from mid-journey.
Why do factories use just-in-time inventory for supplies?
Holding less stock frees warehouse space and cash that would sit idle in stored goods.
