Food Salvage Flashcards
first form of salvage
damaged food containers
seal that will exclude air and will be leak proof at normal temperatures and atmospheric pressure
used to prevent microorganisms
hermetic seal
items not to be sold, distributed, nor consumed
critical
items are safe to be sold
marked as “damage or salvaged”
major
items have no restrictions on being sold
minor
surround the can, make it stronger, and give it more surface metal for better/easier processing
beads
expand during heating to prevent the can from exploding
expansion rings
enlarge or bevel of the rim distorted or uneven depth due ti pressure during the seaming process of can
countersink
principal part of a metal can
body
a hermetic seal
side/end seam
pressure inside of the can is too strong; occurs on the body only, top and bottom of the can are flat
paneling
same as paneling; includes the ends of the cans
buckles
the can literally “swells” at one or both ends - critical bc microbial growth is unknown
swellers
strike on the table and the end pops
springers
push on one end and the other extends
flippers
hole in the can - critical
pinholes
if unable to wipe off, then classify as major; if there is a loss of seal then classify as critical
rust
spangling (internal defects)
usually occurs during processing; heat turns the metal colors
detinning (internal defects)
reaction with contents; metal has changed colors
etching (internal defects)
parts of metal fall into the food
created to replace the “when in doubt, throw it out” practice
Salvage of Chilled/Frozen Food Exposed to Refrigeration Failure
estimate the time of exposure food has been stressed at a temperature of 42 degrees F or greater
Step 1
classify stressed food temperature to determine if the items fall in the “safe” food category
Step 2
foods in which refrigeration is used to maintain quality, not control pathogen growth
safe
